| An apparatus for selectively controlling a flow of fluid includes a valve body, preferable comprised of a flexible tube having an inlet and an outlet. An actuable element, such as a shape memory alloy, is associated with the valve body. The shape memory alloy is responsive to actuation signals, heat or electrical signals, for changing its shape. When its shape changes, it causes a corresponding change in shape of the valve body thereby change a flow of fluid through the valve body. | ||||||

| In a photostrictive device whose light-irradiated surface is irradiated with a beam of light with a specified wavelength to produce a photostrictive effect, the light-irradiated surface is formed with a surface roughness Ra related to the wavelength of light. This increases the light absorption of the photostrictive device, thereby improving the responsiveness. | ||||||
| 8 | High density, three-dimensional, intercoupled optical sensor circuit | US257650 | 1994-06-09 | US5451774A | 1995-09-19 | Stephen C. Jacobsen |
| A three-dimensional circuit structure includes a plurality of elongate cylindrical substrates positioned in parallel and in contact with one another. Electrical components are formed on the surfaces of the substrates, along with electrical conductors coupled to those components. The conductors are selectively positioned on each substrate so as to contact conductors on adjacent substrates to allow for the transfer of electrical signals between substrates. The conductor patterns on the substrates may be helical, circumferential, or longitudinal, in such a fashion that substrates may be added to or removed from the bundle so that the bundle will continue to operate as needed. The cylindrical nature of the substrates leaves gaps or channels between the substrates to which cooling fluid may be supplied for cooling the circuitry. | ||||||
| 9 | Device and method for micro displacement | US951114 | 1992-09-25 | US5287761A | 1994-02-22 | Hiroyuki Fujii; Mamoru Abe |
| A fine displacement device for establishing a measured micro displacement includes first and second plate members disposed in spaced relation to each other to define a gap therebetween with the plate members being secured to each other at opposed portions thereof. An internally threaded hole is formed through one plate member perpendicular thereto and an externally threaded screw is fastened in the hole with an end of the screw abutting against the other plate member. Upon turning the screw in one direction, the plate members will be deformed elastically in a direction perpendicular to the plate members and a distance between a plane of the first plate member and a deformed portion of the first plate member is used as a measure for establishing the micro displacement. | ||||||
| 10 | Heat responsive memory metal actuator | US533453 | 1990-06-05 | US5107916A | 1992-04-28 | Ton van Roermund; Ir P. Besselink |
| An actuator which includes a memory metal element, a substantially constant force counteracting spring, and an actuated element. The memory metal transforms from a martensite structure to an austenite structure at a known temperature. The martensite structure is more easily deformed than the austenite structure. The force applied by the counteracting spring is sufficient to deform the martensite structure throughout the transformation temperature range but insufficient to deform the austenite structure such that at least a portion of the memory metal element undergoes a predetermined stroke in response to the transformation of the memory metal element between the martensite and austenite states. The actuated element is connected to the memory metal element to move therewith. | ||||||

| A thermally respective, monometallic article is isclosed which obviates the need for bonding of dissimilar metals as in a bimetal. The thermally responsive article is formed of an alloy or a metal and has at least two portions. The two portions are characterized by different coefficients of thermal expansion over a given temperature range, the difference being sufficiently large to result in deflection of the article when heated or cooled. In the preferred form of the article, the alloy or metal is present in a first phase in one portion of the article and in a second phase in the other portion. The process for obtaining the dual phase arrangement includes subjecting one portion of an intermediate form to cold treatment, cold reduction, decarburization, or a combination thereof, depending on the material used. A cathode ray tube employing the thermally responsive article as a temperature compensating device is also disclosed. | ||||||

| The invention comprises a compact substantially frictionless positioning device for guiding the motion of an object accurately along one or two axes. The object is supported on a pair of parallel motion solid hinges disposed either side of the axis of motion, each hinge comprising two flexible arms disposed in one plane. Springs are provided at one end of each hinge arm to permit the movement of the object along the axis and to restore it to its rest position when the displacing force is removed. Preferably the hinge arms and the springs are of rectangular cross-section to confine the motion of the object to one plane without the need for additional guides. The displacing force may conveniently be provided by an electromagnetic drive motor, the stator of which may be mounted on a further double parallel motion solid hinge assembly to minimize the change in the center of gravity which would otherwise occur when the object is displaced. A two axis device can be made by mounting a second positioner on the movable part of the first. A variety of forms of the device are possible, facilitating this combination. The positioning device is especially suitable for use as an x-y scanner in scanning microscopy, and may be used for mounting the acoustic lens on the turret of a combined imaging optical and scanning acoustic microscope. | ||||||

| The positioner comprises a fixed frame (1) from which extends a first pair of parallel piezoelectric benders ("bimorphs") (2, 3) which carry an intermediate frame (4). Actuation of the bimorphs (2, 3) causes lateral translation of the intermediate frame (4) with respect to the fixed frame with the bimorphs (2, 3) forming the flexible sides of a parallelogram.Attached to the intermediate frame (4) is a second pair of bimorphs (12, 13) which extend in a direction orthogonal to the direction of the first pair of bimorphs (2, 3) thus permitting a support frame (14) to exercise a deflection in a direction orthogonal with respect to the movement of the intermediate frame (4).The bimorphs used consist of one or two piezoelectric elements carrying two or more electrodes on either side the proper actuation of which causes the benders to bend with parallel end surfaces at all times. | ||||||

| A spindle scans a scanner unit comprising a slender tube portion, a thick tube portion and the like in x and y directions by receiving power from a movable member of a voice coil motor. A mechanical zoom switch is provided with a metal having a low melting point at inside thereof and connects a spring for zoom to the spindle when the metal is solidified. Therefore, the spring constant of the spring for zoom is added to the spring constant of the slender tube portion whereby zoom operation is caused. Meanwhile, when heat is applied from a heating coil to the switch, the metal having a low melting point is softened and the spring for zoom is separated from the spindle. Since the metal having a low melting point is used for the switch, the switch can be switched swiftly and the operational performance of the zoom mechanism is improved. | ||||||
