Title: Constant-current supplying device
Inventor: OHARA MICHIMASA
IPC: H02M3/28
Filed: 1983-09-30
Abstract: PURPOSE:To improve the efficiency as the entire constant-current supplying device by providing the output current of resonance type converters on the basis of the common output current of the converters connected in series. CONSTITUTION:When the common output currents of the resonance converters 2 connected in series increase, detected currents from current detectors S1-S3 increase, and the collector currents of transistors Q1-Q3 decrease by the operations of error amplifiers 31-33 in a current controller 3. As the collector currents of the transistors Q1-Q3 decrease, the supplied currents to light emitting elements of photocouplers PH in the converters 2 decrease, the converting frequency in a VIF converter 25a decreases, and the output currents of the converters 2 decrease. When the common output currents of the converters 2 decrease, the output currents of the converter 2 increases in the contrary operation.

Title: Fail-safe mechanical oil interrupter for screw compressor
Inventor: JIEROOMU SHII ROOCHI
IPC: F25B1/047
Filed: 1993-06-29
Abstract: PURPOSE: To ensure lubrication to a bearing portion and a working portion without employing expensive devices by preventing oil from leaking to a bearing and a working chamber during compressor shutoff and allowing oil to flow at the start of the compressor. CONSTITUTION: When a motor 36 is not in operation, a compressor is shutoff. The exhaust gas compressed prior thereto returns to a working chamber directly. At that time, an exhaust check valve 41 is seated to prevent reverse flow. However, the initial reverse flow before the valve is seated excites the reverse rotation of a rotor 22. The reverse rotation decreases the pressure in an exhaust region 62, and the pressure on an end face 66 of a valve member 56 drops rapidly to a pressure below the pressure in an intake region 60. The pressure difference in front of and in rear of the spool valve 56 acts as a valve to shutoff a common oil supply passage 52. When the compressor is started, gas is compressed and an exhaust pressure is generated in the exhaust region 62. The valve member 56 forces the common oil supply passage 52 to an open position.  Pressure is simultaneously generated in an oil separator 42. Oil flows from an oil tank 44 through the passage 52 to bearings 30, 32 and an oil injection port 50.

Title: Video camera
Inventor: KITANO MASUO
IPC: H04N9/73
Filed: 1983-09-30
Abstract: PURPOSE:To attain reproduction for a reproduction picture in an optimum white balance state by using plural signals obtained by sampling the electric signals outputted from an image pickup device at plural points having time intervals respectively to decide the white balance. CONSTITUTION:When an image pickup button is pushed, a control circuit 27 samples and quantizes color difference signals S4 and S5 by A/D converters 21 and 22 at specific time intervals to store them to a memory circuit 30. When the circuit 30 is overflowed, the oldest signal is erased to memorize a new signal. The circuit 27 calculates the mean value of each digitized color different signal stored in the circuit 30 every time a new signal is stored to the circuit 30. The mean value is defined as S23 and S24 respectively to undergo D/A conversions 26 and 28 and the result is compared with the outputs of reference voltage generating circuits 25 and 29. Then comparison signals S33 and S34 are outputted. Then the circuit 27 sends outputs S18 and S19 of A/D converters 15 and 19 to gain control circuits 6 and 7 while monitoring signals S33 and S34 to control the gains of color difference signals S1 and S3.

Title: Process synchronizing method
Inventor: HASEGAWA SATOSHI
IPC: G06F9/46
Filed: 1986-08-01
Abstract: PURPOSE:To decrease the past state value to be stored in a process by circulating the token ownership among plural processes that proceed their processings with mutual exchange of message and rolling back the ownership to a stage preceding by a single token cycle by detecting a fault in a single token cycle. CONSTITUTION:Each process receives a token T via a control block 100 and decides via a control block 101 whether its own process is equal or not to a process having the next token ownership. If so (YES), it is decided that the abnormality exists. In such a case, a token owner process turns the value of a time stamp into the value older by a single token cycle via a control block 107. Simultaneously, a system state variable is also set its past state to set a roll-back processing request for the request of a retrial.

Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To control an optimum operation state even at transitive time by holding learning data even after the learning of a neuro part ends, correcting a set of the held data, and performing the relearning of the neuro part. SOLUTION: Even after the learning of the neuro part 4 ends, operation state data and learning data on a target manipulated variable are held in a learning data set memory 7 and when learning data is obtained in an operation state, the held learning data set is corrected to perform the relearning of the neuro part 4. The learning data in this case is a pair of a neuro entrance and a neuro exit. Further, the learning data set memory 7 is stored with throttle opening extent data and engine rotating speed data constituting the neuro input and also stored with a manipulated variable as the neuro exit. Then this manipulated variable is obtained by adding a feedback value to the neuro output.

Abstract: PROBLEM TO BE SOLVED: To accurately adjust the optical axes of two optical systems to constitute three-dimensionally measuring parallel type stereo cameras so as to become parallel to each other by a simple method. SOLUTION: A plane chart 202 having two parallel straight lines L1 and L2 separate by the same distance B as a center distance B of two optical systems of stereo cameras 201 and two parallel lines L3 and L4 orthogonal to these two parallel straight lines, is placed in a prescribed position to the stereo cameras 201.

Title: Optical information recording and reproducing device
Inventor: KUROKI YUZURU
IPC: G11B20/22
Filed: 1983-09-30
Abstract: PURPOSE:To prevent a reproduction signal from having a DC component before it is binary-coded in a reproduction mode with an optical recording disk having a sector structure, by modulating and recording a signal obtained after an exclu- sive OR is secured between the data given from a sector buffer memory and a code string of an artificial random series. CONSTITUTION:The parallel data of four bits is delivered from a sector buffer memory 18 in the timing of a CLK1. Then an exclusive OR is obtained forever bit between said parallel data and the output of a scramble ROM34 which uses the output of a counter 33 using the CLK1 as a clock input as an address input. Then the parallel data is turned into an address input of an ROM35 for modulation and then converted into the modulation data. This modulation data is loaded to a shift register 36 in the timing of the CLK1 and then turned into the serial data by a CLK2 to be supplied to a semiconductor laser driving circuit. An exclusive OR is secured between the modulation data and a random code series by the scramble ROM. Thus it is possible to convert a fixed repetition data into a random form and to modulate it. Then the input data is converted into a random form before modulation, and the ratio between ''1'' and ''0'' of the modulation data is bronght close to 1:1.

Filed: 1983-09-30
Abstract: PURPOSE:To absorb waveform distortion, phase jitter, phase jump and offset phase difference by allowing a PLL circuit to generate the 1st output and an intermediate output and generating the 2nd output with the intermediate output and the 2nd input clock. CONSTITUTION:The 1st input clock PC is frequency-divided by a P-notation counter 11 operated by the 2nd input clock FC to obtain an intermediate clock IC.

The outputs PO and FO are waveform-shaped by a waveform shaping circuit and become respective output clocks. Thus, the waveform distortion, phase jitter, and phase jump are absorbed by the PLL circuit 12 and also the frequency of the clock IC is increased to decrease the offset phase difference.
