21	Scroll part manufacturing and its device for scroll fluid suction and drain equipment	JP2831281	1981-03-02	JPS57143101A	1982-09-04	FUKUHARA MASAICHI
PURPOSE: To reduce shaping in such a way that a wadding is embedded into one of two molds equipped with scroll grooves, and after a material is filled into the other, and hardened, the wadding is extruded, and then reducing the number of releasing tapers at the scroll portion when forming. CONSTITUTION: A second mold 7 is provided which is situated at is inside with a first scroll groove 1 having a wedge-shape in its section, owns a second scroll groove 2 having a rectangular shape in its section on one side, and owns a first mold 3 having a plurality of openings 4, a ring-shaped concave part 13 and a sprue 14 on the other side. Then, a wadding 5 in scroll shape equipped with a plurality of pins 6 is inserted into the first groove 1, and the first and second molds 3, 7 are linked together. When molten metal material is infused through the sprue 14, the material is filled into the second groove 2, a space 9 and the concave part 13, and hardened. After hardening, linkage of the first and second molds 3, 7 is released, and when the wadding 5 is extruded, the hardened material is readily removed from the first mold 3. Thus, the number of releasing tapers when forming can be reduced. COPYRIGHT: (C)1982,JPO&Japio

An engine driven with the air pressure is provided to perform the power generation and a shift function with the rotation by the high air pressure. An engine driven with the air pressure comprises: a turbine(110~160) of a cylindrical shape, having a plurality of grooves(111,121,131,141,151 and 161) along a side part in regular; a shaft(170) located in a central part of the turbine in order to deliver the torque of the turbine; and nozzles(210,220) for supplying the air of the high pressure to the side part of the turbine. The nozzle sprays the air of the high pressure with transport units(310,320) while moving a plurality of the turbine side parts.

PURPOSE: A regular speed driving device of a pneumatic power generator is provided to guarantee the high electric power production efficiency with normal pressure of compressed air by supplying a fixed quantity of compressed air to an air cylinder for driving a gear box through a double-action solenoid valve. CONSTITUTION: A regular speed driving device of a pneumatic power generator comprises a timer(3) for controlling a double-acting solenoid valve(1), a double-acting solenoid valve, an air cylinder(4), a fly wheel-mounted gear box(20) and a cylinder. The timer for controlling the double-acting solenoid valve is connected with an air duct of a pneumatic tank. The double-action solenoid valve is controlled by the timer. The air cylinder is driven by the air supplied sequentially by the double-action solenoid valve. The flywheel-mounted gear box is connected to the end of the piston of the air cylinder eccentrically. The cylinder transfers the power of the generator.
25	SURGICAL PNEUMATIC MOTOR	PCT/US2005008829	2005-03-16	WO2005110252A2	2005-11-24	DEL RIO EDDY H; DOUGLAS A PERRY
A surgical motor designed to for power, noise and heat reduction for powering surgical tools where the surgical motor is modular constructed to house the vane motor for generating power in one module and the chuck and output shaft in the other module. A coupling mechanism for transmitting rotary motion from the vane motor to the output shaft includes balls made from elastomeric material to reduce vibrations and noise. The vane motor includes vanes that are contoured on the bottom edge, the spindle is undercut adjacent the vanes and peripheral edge of the spindle is grooved to enhance power, the inlet opening to the vanes are repositioned to increase the volume of inlet air, the inner surface is contoured to define a crescent seal adjacent to the spindle outer surface, the inlet and outlet to the spindle are repositioned to increase the power stroke of the vane, the discharge holes are oriented so that the vane edge sees a uniform contact surface during each revolution, the cylinder includes flow passages for cooling the cylinder and for flowing a portion of the air over the support bearings mounted downstream of the cylinder and including a return passageway to feed the inlet holes so that all pressurized inlet air are directed to impinge on the vanes and seal means, one made operable in situ and the other operating adjacent the inner race of the bearing prevents leakage of oil into ambient and into path of the surgical tool and the surgical motor includes an insert housing radially spaced from the main housing defining an air gap for reducing heat and the in the handle and resilient mounting means to isolate the vibrations to reduce noise and a thrust path bypassing the vane motor.
