| PURPOSE: To realize the titled displacement generator, which generates a constant quantity of displacement without depending on temperature, at a low cost and high reliably by a method wherein a capacitor, whose code of the temperature coefficient of electrostatic capacity is different from that of the temperature coefficient of electrostatic capacity of a bimorph piezoeletric-element, is connected to the bimorph piezoelectric-element in series. CONSTITUTION: A bimorph piezoelectric-element 3 and a capacitor 2, whose code of the temperature coefficient of electrostatic capacity is different from that of the temperature coefficient of electrostatic capacity of the bimorph piezoelectric-element 3, have been mutually connected in series in such a condition as to be impressed an AC driving voltage. The driving voltage is impressed on the bimorph piezoelectric-element 3 through the intermediary of a capacitor 2 for compensation connected to the bimorph piezoelectric-element 3 in series by an AC electric power source 1 whose internal impedance is sufficiently smaller than the impedance of the bimorph piezoelectric-element 3. The bimorph piezoelectric-element 3 shall be the one laminatedly made of two sheets of plate material 3a and 3b, which are a parallel connection type and consisted of piezoelectric- material, for example. The polarizing direction thereof is the thickness direction of the plate material and the polarizing direction shall be the same direction as that of the material.

| PURPOSE:To obtain a blower adapted for local cooling of a narrow part having small current consumption with a simple structure by partly bonding a piezoelectric plate, supporting a thin elastic plate as a vibrator through a damper to a stationary base in a cantilever structure, and applying AC drive voltage to the vibrator, thereby rocking the end of the plate. CONSTITUTION:Part of the base end of a thin metal elastic plate 1 is pressed to form a wavy damper 3, the end is supported to a stationary base 4 in a cantilever structure, and piezoelectric plates 3 are bonded to between the free end of the plate 1 and both front and back surfaces of the damper 3. Or, the damper 3 is not formed in a wavy shape with the plate 1, but two silicone rubber plates can be laminated. With this structure, AC voltage is applied between the plates 2 and 1 to rock the free end of the plate 1, thereby producing an air stream. In this manner, the structure is formed in an extremely thin shape, and can be readily associated in a complicated narrow housing. | ||||||
| 85 | Thermo sensitive valve | JP15572681 | 1981-09-30 | JPS5857573A | 1983-04-05 | ABE KOUHEI; ASHIKAWA MASATAKA |
| PURPOSE:To enable to sense to the temperature of water and to automatically open and close the flow of water by a method wherein the martensite transformation point of a spring, which is one of two springs installed within the valve and acts for parting a valve from a valve seat, and the Curie point of a thermosensitive magnetic material are rendered to be nearly equal to each other. CONSTITUTION:A thermo sensitive device consisting of the tension spring 5, which is made by forming a memory alloy in corrugated shape, and a compression spring 6 made of ordinal spring material is provided within a casing 1. When water with elevated temperature comes in the casing 1 from an intake 12 and the temperature of the valve 4 made of thermo sensitive magnetic material exceeds its Curie point, the valve 4, which is firmly attracted by a permanent magnet 2, is shifted by being pushed by the pressure of the water, because of the disappearance of the attractive force of the valve 4. Consequently, the water flows into the valve and causes to heat the spring 5 of the thermo sensitive device, resulting in transforming the memory alloy from its martensite state to its mother phase and abruptly contracting the device and consequently abruptly discharging the water through the valve from efflux holes 11. | ||||||

| PURPOSE:To obtain a small-sized electricity-displacement transducer free of mechanical loss due to friction, etc., by outputting the quantity of electricity applied to an electronic heat exchanger as variations of nozzle back pressure with the displacement of a bimetal. CONSTITUTION:An electricity-displacement transducer 10 which utilizes Peltier effect generates variations in heat between metallic plates 16 and 17 by a difference between potaintials applied to the electrodes 23 and 24 of a thermoelectric element 11, and a bimetal 19 flexes according to the variations in heat to control opening of a nozzle 20 for jetting air. Then, variations in air pressure at this time are amplfied by a pilot valve 25 to be led out as an output signal POUT, which is supplied to a pressure-electricity transducer 26. Its output IFB is supplied as a feedback signal to a preamplifier 12 through an adder 27. | ||||||

Mit der Erfindung wird ein Aktuator in Form einer Schraubenfeder (S) vorgestellt. Die Bewegung des Aktuators in verschiedenen Richtungen wird dadurch erzeugt, daß an einem Ende der Spiralfeder Zugstränge (Z1,Z2,Z3) angebracht sind, welche zum Zusammenziehen der Feder entlang der Feder durch Führungsösen (OE) geführt sind und am anderen Ende frei austreten. Zum Strecken der Feder gegen eine von außen einwirkende Kraft sind Zugstränge (D1,D2,D3) vorgesehen, welche den jeweils oberen und unteren überlappenden Rand (R1,R2) von zwei benachbarten Schraubenfederwindungen (W1,W2) in Form von Schlaufen umfassen. Diese Zugstränge verlaufen in Führungsschlitzen (SL), die dafür entlang des Aktuators vorgesehen sind. Übt man nun Zug auf die frei austretenden Zugstränge aus so läßt sich durch eine gezielte Streckung oder Zusammenquetschung des Aktuators eine Bewegung in verschiedenste Richtungen erzielen. |

A movement actuator includes an elongate filament made of a flexible material, and a strip of shape memory alloy disposed on the surface of one side of the filament. The shape memory alloy is responsive to actuation signals, heat or electrical signals, for changing its shape and when its shape changes, it causes the filament to move, i.e., bend, to accommodate the change in shape of the alloy. Also included is a signal supply device for selectively applying heat signals or electrical current to the strip of shape memory alloy to cause the alloy to change its shape and cause the filament to bend. Other patterns for the shape memory alloy could be disposed on the filament to cause other kinds of movements. For example, a helical pattern of the shape memory alloy about the filament would cause the filament to twist when the helical pattern were caused to shorten or lengthen. |

Apparatus for non-planar treatment of a workpiece utilizing exposure beam lithography includes a vacuum chamber (4), an exposure beam generator such as an electron beam generator (8) disposed in the chamber for directing a beam (12) towards a work location (16), a chuck (44) disposed in the chamber for holding and positioning the workpiece (40) at the work location, a rotary motorized stage (48) disposed in the chamber and responsive to first control signals for selectively rotating the chuck, and thus the workpiece, to thereby expose different areas of the workpiece to the beam, and a linear motorized stage (56) disposed in the chamber on which the rotary stage is mounted, said linear motor being responsive to second control signals for selectively moving the rotary stage and thus the chuck and workpiece in a linear direction which is generally parallel with the axis of rotation of the rotary stage. The workpiece is thus exposed over additional areas by operation of the linear stage. A controller supplies first and second control signals to the rotary stage and linear stage respectively to selectively effect the operation thereof. |

| 97 | Displacement generation device | EP84302051.2 | 1984-03-27 | EP0124250B1 | 1987-08-26 | Tanuma, Chiaki |
| A displacement generation device includes: a bimorph piezoelectric vibrator for receiving an externally applied drive voltage and for generating a displacement in response to the drive voltage; and a temperature-compensation capacitor element electrically connected in series with the piezoelectric vibrator. The capacitor element has a capacitance with a temperature coefficient with the same absolute value but opposite sign to that of the capacitance of the piezoelectric vibrator. When the capacitance of the piezoelectric vibrator changes in accordance with a change in the ambient temperature, the capacitor element properly changes the drive voltage supplied to the piezoelectric vibrator, thereby compensating for the displacement of the piezoelectric vibrator caused by the change in ambient temperature. | ||||||

The invention consists of acompact substantially frictions positioning device for guiding motion of an object accu- ely along one or two axes. The object is supported on a )ck (13), which is attached to the inner ends of two pairs of Kible arms (14) connected to bars (15). Arms (14) form a uble support assembly which constrains block (13) to otion along a single axis, providing bars (15) are allowed to ove inwards slightly as the block (13) is displaced. This is nieved by supporting bars (15) on four springs (16) from ed blocks (17). Springs (16) exert a restoring force on bars i) as block (13) is displaced, resulting in block (13) returning its rest position when the displacing force is removed. ocks (17) may be mounted on a connecting plate which is pported on a second double hinge assembly comprising ns (19) and restoring springs (18), permitting a similar otion of block (13) along an axis at right angles to the first is. Motion is imparted to block (13) by means of elec- magnetic drive motors. The device is especially suited for e as an x-y scanner in scanned image microscopy and can used to scan the position of an acoustic lens in a combined inning acoustic and imaging optical microscope. |
