Title: Constant current control circuit of resistance welding machine
Inventor: MAKINO MAKOTO
IPC: H02M7/48
Filed: 1983-12-24
Abstract: PURPOSE:To control to accuratly, speedily set effective value even when power source and load fluctuate by calculating effective value of current that flows in a circuit which connects a power source circuit to a welding gun through an inverter, comparing it with set value and controlling the inverter. CONSTITUTION:When the inverter 5 operates and welding current is supplied from the power source circuit 1 to the welding gun 8, the current is detected by a detector 9, and made to voltage of waveform corresponding to effective value of the current by an arithmetic circuit 10. The voltage is compared with voltage corresponding to effective value of current value set by a current setting device 14 by a comparator 17, and when the two coincide, a signal of low level is outputted from the comparator 17. The signal controls a pulse width control circuit 21, rises up synchronously with output pulse of an oscillator 22. Pulse current that was flowing in transistors 51, 52 or 53, 54 is cut off by lowering of output of the circuit 21. Thus, the purpose can be achieved.

Title: Acceleration/deceleration control method of motor
Inventor: MURAKAWA TOSHIHIRO
IPC: H02P29/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To suppress vibration without changing control rules with a conventional controller, by performing control by an acceleration time that is equal to or more than the shortest time being derived from the response time of a machine mechanism that is interlocked to the rotary shaft of a motor, and a deceleration time that is determined with reference to the natural frequency of the machine mechanism. SOLUTION: When a vibration amplitude stops in a process where it gradually increases in negative direction within a period Tβ of 2/4-3/4 of a period T that is determined by the natural frequency of a robot, the polarity of vibration (b) when deflection on deceleration returns differs from that of natural vibration (a). The amplitude of actual measurement synthetic vibration (C) after the stop becomes the difference between the vibration amplitude where the deflection returns and the natural vibration in the attenuation process, thus reducing the vibration on stop. An acceleration time Ta is set to the shortest response time or more of a robot, and the robot can be subjected to trapezoid or S-control and can be accelerated to a specific speed during the acceleration time Ta. Vibration being generated due to the inertia of a drive force transfer system when the robot stops is determined due to the control at a deceleration stage.

Title: Method for driving simple matrix type lcd
Inventor: YAMAZAKI TSUNEO
IPC: G02F1/133
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To keep reliability of a liquid crystal cell and to suppress the occurrence of a flicker by adjusting a phase of a modulation signal for a frame signal for reducing the intensity of the caused flicker. SOLUTION: The intensity of the caused flicker IF is reduced by adjusting the phase of the modulation signal M SIG for the frame signal FRM and driving an LED. On the other hand, when a phase value N expressed by the number of latch clock signal LATCH CK is an odd number, the probability that a voltage of the same polarity, that is, a DC voltage is applied continuously to one cell becomes high. Thus, by setting the phase value N as an even number, the reliability of the liquid crystal cell is kept. Further, by setting the condition that when the number L/F of the latch clock signal LATCH CK per one frame is divided by the ratio (fL/fM) /2 of a frequency, the quotient becomes an even number, the probability that the voltage of the same polarity is applied to one cell is reduced.

Filed: 1986-10-14
Abstract: PURPOSE:To perform the inspection of a code error without using a memory, by estimating an even-th symbol and an odd-th symbol in each block being inputted in order, separately, and performing the arithmetic calculation of a syndrome corresponding to each row of an inspection matrix. CONSTITUTION:Since a clock signal phi 1 corresponds to the even-th symbol in an even-th block, or the odd-th symbol in an odd-th block, a first register 55 generates the syndrome So-o when the symbol is supplied in the odd-th block out of a code word. A register 56 generates the syndrome So-e when the symbol is supplied in the even-th block out of the code word. A data selector 61 takes out the syndrome So-o after the arrival of a clear signal CL1 by a switching signal SLCT in which a clear signal CL3 supplied from a terminal 72 is frequency-divided by 1/2, and outputs a taken out syndrome from a terminal 73 as the syndrome So. In such way, it is possible to perform the arithmetic calculation of the syndrome.

CONSTITUTION: A reflecting member 4 and an eccentric pin 8 are attached to a holding console 7, and light receiving elements 3 (3a to 3d) are positioned to assembled a light receiving part. Then a projected light spot image of a light projecting element integral with a lens holder 6 is formed at a predetermined distance, and the light receiving part is moved while observed received 3 and reflected light output to fix it to the holder at a position with the highest output.
