Title: High speed processing system for image processor
Inventor: SOGA KOJI
IPC: G06T7/00
Filed: 1990-02-28
Abstract: PURPOSE:To perform the comparison arithmetic processing of the image information at a high speed by providing a comparison arithmetic part between a control part and an image memory part, comparing immediately an address designated by the control part in an image memory part with the color information read out of the image memory part, and outputting the result of the comparison to the control part. CONSTITUTION:A control part 2 designates an address of an image memory part 1 storing the desired image information to be compared and then reads out the color information. This color information is fetched to a comparison arithmetic part 4 for immediate comparison arithmetic. At the same time, the color information to be compared and set to a comparison register part 3 is fetched by the part 4. Thus the part 4 performs immediately the comparison between both color information. The result of the comparison is outputted to the part 2 as it is. Therefore the result of comparison is read out of the part 4 at the same time point when the part 2 usually designates and reads out the address of the part 1. Thus the comparison arithmetic processing of the image information is carried out at a high speed.

Title: Annealing method for single crystal wafer
Inventor: SAKURAI JIYUNJI
IPC: H01L21/265
Filed: 1981-03-31
Abstract: PURPOSE:To prevent a wafer from cracks by a method wherein energy beam scans for annealing are conducted in directions different from the direction of cleavage in a single crystal wafer. CONSTITUTION:A single crystal wafer 1 of a face direction (100) is fixed upon an X-Y platform and an angle theta is formed by an axis F-F at a right angle to a facet 3 and an axis X or Y. The axes X and Y are in the direction of <100>, a direction of difficult cleavage, when theta=45 deg.. Under such circumstances, the energy beam focus 7 scanning in the direction X or Y does not render the wafer easy to break during handling after treatment. The possibility of breakage is far less than after a beam application along the direction of <110>, a direction of easy cleavage, even when theta is chosen anywhere between 22.5 deg. and 67.5 deg.. By following this method, thermal distortion remaining in the wafer 2 does not lead to breakage, and therefore annealing and single crystallization can be effected can be effected at a fast pace. Accomplishing a same result is a scan conducted in a direction <100> intercepting at an angle theta the axis X or Y at a right angle to or in parallel with the facet 3.

Title: Driver of ferrite phase shifter whose flux is controlled
Inventor: DEIBITSUDO DABURIYU UORISU
IPC: H01P1/19
Filed: 1990-02-28
Abstract: PURPOSE: To make a whole driving circuit small and low-cost by saturating a core with magnetism or 'resetting' it by using active feedback control of a monostable circuit by an external timing control terminal. CONSTITUTION: The voltage developed by a converter 16 added in series with a wire 12 is applied to the external timing terminal of the monostable circuit M1 to perform closed loop control. Consequently, the monostable circuit M1 is saturated and left in the semistable state long enough to 'reset' the magnetic flux in the core 14. Once the saturation is attained, a sharp current spike is encountered, and consequently a sharp increase in the voltage output of the converter 16 further increases to put the monostable circuit M1 speedily back to a stationary stable state by its external timing terminal. Thus, the monostable circuit M1 having active feedback resets the magnetism of the ferrite core 14 in the ferrite phase shifter, so the electronic driving device can be constituted to small size at a low price.

Filed: 1988-03-02
Abstract: PURPOSE:To facilitate the build-up of the ordering communication with the digital communication system by sending continuously an optical pulse subject to phase modulation by a voice signal to an optical submarine cable and allowing the reception side to apply phase demodulation to the pulse and to reproduce it into a voice signal. CONSTITUTION:Since the period of an output pulse of a sender side pulse oscillator 6a is synchronized with the clock signal period, when the output signal of a modulator 5a is used for the clock signal, the period of the output pulse is fluctuated proportional to the amplitude of the voice signal. The output pulse of the pulse oscillator 6a is converted into an optical pulse by an electrooptic converter 8a at the sender side and sent to a submarine cable 2 and propagated through an optical fiber in the cable 2. The optical pulse is subjected to waveform distortion in the optical fiber an recovered by an optical submarine repeater 1, reaches an phtoelectric converter 9b at the receiver side and is converted into an electric signal by a converter 9b. Then only timewise jitter component of the pulse is extracted by a demodulator 7b as a voltage. Thus, the output of the demodulator 7b is connected to the receiver side telephone set 3b to reproduce the input voice of the sender side telephone set 3b.

Abstract: PURPOSE:To permit a lot of recording members to be gathered without making a sorter size larger, by providing a control means for actuating a distribution unit in accordance with an accommodation capacity of an accommodation unit of a sorter device. CONSTITUTION:When copy papers pass through a paper discharge roller 19 and reaches a detection switch 21, a sorter device S detects them so that a transportation roller 22 rotates to transport the copy papers to a bin 23. The transportation roller stops its rotation in a prescribed period of time after the rear edge of the copy papers have passed the switch 21. When the sorter device S is in a sorting condition at the time, a bin shift cam 24 is rotated in the direction shown by the arrow when the copy papers have been accommodated in a bin 23 and a cam position switch turns on and off once to detect that the bin 23 has been shifted by one pitch. When the sorter device S is not in a sorting condition, all of the copy papers are accommodated in the bin 23 located at the uppermost position and when a prescribed number of the papers have been accommodated, the bin is shifted by one pitch for further accommodation. When a prescribed number of the papers has been reached, the accommodation of them are effected by shifting the bin by one pitch and then a lot of recording members can be gathered stably.
