Title: Hydrogen absorbing type refrigerator
Inventor: MARUHASHI TSUTOMU
IPC: F25B17/12
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a switching valve or an opening and closing valve by shifting the starting time of contacting hydrogen to a thermal medium in the repeated transfer of cells being provided with chambers filled with hydrogen absorbing alloys and connected to others between a hydrogen driving part and a cold heat outputting part. SOLUTION: Cells S that are provided with upper row chambers S1, middle row chambers S2 and lower row chambers S3 each of which is connected to others through a hydrogen path S4 and filled with the hydrogen absorbing alloys are used. The system is provided with a hydrogen driving part α transferring the hydrogen inside the upper row chambers S1 to the lower row chambers S3, a first cold heat output part β transferring the transferred hydrogen to the middle row chambers S2 and a second cold heat outputting part γtransferring the transferred hydrogen to the upper row chambers S1. In contacting each of the chambers S1, S2 and S3 to the thermal medium, the starting timing of the one chamber contacting to the thermal medium is shifted from the starting timing of other chambers contacting to the thermal medium.  Therefore, the malfunction of the delay of transferring the hydrogen by pressure loss during the transfer of the hydrogen and the deterioration of cooling efficiency are prevented.

Title: Video signal transmitting equipment
Inventor: SHIMOKOORIYAMA MAKOTO
IPC: H04N19/85
Filed: 1988-02-08
Abstract: PURPOSE:To obtain a video signal with high resolution in any case using a static image and a movable image by executing the field offset sampling of a video signal inputted through a space filter whose pass band is controlled based on the moving distance of an input video signal. CONSTITUTION:A coefficient unit 305 outputs a value obtained by multiplying a movement factor K outputted from a movement detector 304 by an output of a space filter 302 and a factor unit 306 outputs a value obtained by multiplying a movement factor 1-K by an output of a space filter 303. Namely, the output of the space filter 302 with a narrow band is increased in case of large movement or the output of the space filter 303 with a wide band is increased in case of small movement as an output of an adder 307. Thereby, the pass band of the space filter 302 is narrowed in case of a large moving distance to prevent the generation of return interference, and in case of a small moving distance, the pass band of the space filter 302 is expanded to transmit an image with high resolution.

Title: Device and method for trimming electronic parts
Inventor: MURATA SEISHI
IPC: H01G4/255
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To shorten the trimming time of electronic parts and reduce the occurrence of the cracking and chipping of the parts by providing a diamond tool carrying a single pyramid grain of diamond attached to one end and a rotating shaft having a front end to which the diamond tool is fixed. SOLUTION: After the continuous measurement of the electrical characteristic of electronic parts 50 is started, a diamond tool 30 is gradually advanced toward the parts 50 by slowly rotating a cam 25 from a state where the tool 30 is rotated at a high speed together with a rotating shaft 15 by means of a motor 10. Then an electrode 52 is cut little by little with the single point diamond 35 of the tool 30 while the variation of the characteristic of the parts 50 is monitored with an electric measuring instrument. When the diamond 35 cuts the electrode 52, the recessing and projecting sections 25a of the cam 25 automatically remove the cut dusts by finely vibrating the tool 30 in the axial direction. When the characteristic of the parts 50 reaches a target value, a driving section 41 terminates the cutting operation by raising the tool 30 through an arm 40 and the shaft 15.

Title: Resistance control element
Inventor: HIKITA MAKOTO
IPC: H01L49/00
Filed: 1987-02-06
Abstract: PURPOSE:To control the resistance value of metal or semiconductor, by controlling the effective mass or the scattering time of electrons in a solid body. CONSTITUTION:A control electrode 13 (e.g., Pt with a thickness of 0.1mu m) and a dielectric thin film 10 (e.g., PbTiO3 with a thickness of 1mu m) are formed on an SrTiO3 single crystal substrate (not shown). Many pieces of thin wire conductors 11 with a width of 1 mum or less are connected between electrodes to be controlled 12a and 12b on the dielectric thin film 10. Thus a conductor layer is formed (e.g., a Pt layer with a thickness of 0.1 mum is etched at a width of 30 nm and at a pitch of 70 nm). A voltage is applied across the control electrode 13 and the electrode to be controlled 12a from a power source 14. Then, the dielectric layer 10 is polarized. Then, a mutual reaction with electrons in the thin wire conductors 11 is generated, and the effective mass or the scattering time of the electrons in the conductors 11 is changed, thereby the conductivity between the electrodes to be controlled 12a and 12b is changed. Thus an element, whose resistance can be controlled at a cryogenic temperature is obtained.

Abstract: PURPOSE: To enable the visible images of high gradation characteristic free from ground fogs to be obtained by applying such alternating biases as the ones which are developed sufficiently at image end portions to a toner support in the first developing part and applying such alternating biases by which image density is obtained in the second developing part.  
     CONSTITUTION: A photoreceptor 11 has a back electrode and moves in the arrow A direction. A permanent magnet 14 is fixed in a non-magnetic sleeve 13 and the sleeve 13 turns in the arrow B direction. The magnetic toner 15 of insulation characteristic is conveyed by the revolution of the sleeve 13 and its thickness is controlled by a magnetic blade 16. The toner is imparted with charge by the friction charging of the sleeve. The blade 16 and sleeve 13 are kept in a conductive state and are applied with the first alternating voltages by a power source 18. The second developing part is also similar, and they are applied with the second alternating voltages by a power source 19. This enables the distinct images of good fine line images and of high gradation characteristic to be obtained.
