Title: Moving and positioning device
Inventor: HIRAHARA TAKAO
IPC: G05B19/18
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To move a body while avoiding a movement error due to hysteresis by judging that there is the hysteresis when a detected error is larger than a reference value, and moving the body from an actual movement position corresponding to an initial movement command value to a specific position. SOLUTION: A mode judgement is made (step 52). For the mode judgement, a position detecting means detects the error of the detected actual movement position and judges whether or not the absolute value of the error is larger than a small reference value. When the absolute value of the error is larger than the reference value, it is judged that there is hysteresis and a hysteresis removal movement mode is entered (step 54). The body is moved from the actual movement position corresponding to the initial movement command value by a movement distance corresponding to a specific movement command value in the same direction as the initial movement direction and then moved in the opposite direction by the movement distance corresponding to a specific movement command value, so that the body can be moved without being affected by the part where the hysteresis is present.

Title: Vibration detector and vacuum cleaner
Inventor: SENDA NORIAKI
IPC: H01H35/14
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum cleaner with a vibration detector short-circuiting between electrodes even when insulating layers are generated on the pair of electrodes or a moving member. SOLUTION: A vacuum cleaner body is connected a hose provided with a rolling detecting sensor 18, and is supplied with commercial alternating current source to make the cleaner ready for cleaning. A cleaning action rolls a conductive ball 25 in the rolling detecting sensor 18 to short-circuit a pair of electrodes 24a, 24b. Electric current flows between the electrodes 24a and 25b through a resistor from a reference electric source. The electric current flows through a capacitor that is connected serially with the sensor 18 and is not charged, thus the amount of the current flowing between the electrodes 24a and 25b increases. An opening/closing detecting mean detects the ON state. Large current flow exfoliates oxide films generated on the surface to expose conductive part constantly. A travel of the ball 25 across the electrodes 24a and 25b infallibly presents a short-circuit.

Title: Variable displacement compressor
Inventor: TABUCHI YASUO
IPC: F04B27/14
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To prevent an engine load from increasing excessively even when the engine load of a vehicle increases in acceleration. SOLUTION: A pressure Pc in a swash plate chamber 126 is controlled based on a difference pressure ΔP between a suction pressure of an engine and a pressure of a compression mechanism Cp to reduce discharge capacity when an engine load increases. Consequently, since compression work (discharge pressure X discharge capacity) of the compression mechanism Cp is reduced when the engine load increases, it is possible to prevent the engine load from increasing excessively even when the engine load of a vehicle increases in acceleration.

Filed: 1987-12-07
Abstract: PURPOSE: To provide a highly reliable inexpensive cryogenic refrigerant supplying device which does not cause any failure by providing a control means which switches a flow passage switching means to the atmosphere side when a cryogenic refrigerant flows without being heated to a prescribed temperature after the temperature in a transfer pipe is detected and an object to be cooled is cooled or a power failure occurs. CONSTITUTION: Usually, a cryogenic refrigerant flows to a heater 7 through a three-way valve 10 after cooling an object 3 to be cooled. When the heat load to the object 3 becomes abnormal and such abnormality as the disconnection of the heater 7, etc., occurs, the temperature drop at a normal-temperature pipeline 8 is detected by means of a temperature switch 12 and the cryogenic refrigerant flowing out from the object 3 is made to flow to a cryogenic refrigerant discharge pipe 11 so as to prevent the refrigerant from flowing in the transfer pipeline 8. When a power failure occurs, the temperature switch 12 becomes inoperable, but the three-way valve 10 is always maintained in such a normal state that the valve 10 can be connected to the discharge pipe 11.

Title: Stereoscopic image pickup device and stereoscopic display device
Inventor: OKANO FUMIO
IPC: H04N13/02
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a stereoscopic image pickup device simple in constitution by turning plural lenses into the optical fibers of equal length whose refractive index is enlarged from a peripheral part to a center part. SOLUTION: Instead of a lens group comprising the plural lenses in this stereoscopic image pickup device, the lens group is constituted by using the plural optical fibers 21. That is, the optical fibers 21 provided with refractive index distribution (graded index distribution) for which the refractive index is enlarged from the peripheral part to the center part are used as the optical fibers 21. Thus, light made incident on the respective optical fibers 21 is not leaked to the outside of the fibers and interference mutually between the optical fibers is eliminated. Further, the light inside the fibers meanders by the refractive index distribution of the optical fibers 21 and is image-formed at a certain specified point PT1 and the light emitted from the end face 21a of the optical fiber advances straight in an emitting direction and is image- formed at a point PT2 .  At this point, the length of the respective optical fibers 21 is turned to the length for forming the erect image of an object on an emission end face and arraying is performed so as to two-dimensionally arrange respective light incidence/emission end faces on the same plane.
