Abstract: PROBLEM TO BE SOLVED: To detect a correct position and a correct speed of a motor by counting pulse signals output from pulse clocks which generate the pulse signals wish a smaller cycle than that of pulse signals output from an encoder. SOLUTION: An error operation part 4 compares a target value stored in a memory 3 with position or speed information of a motor M operated at a position or speed operation part 11, and calculates a difference. A compensation operation part 5 operates an adjustment amount based on the difference, and a pulse width modulation(PWM) generator 6 controls the motor M via an amplifier A on the basis of the adjustment amount. A pulse clock 81 from a pulse generation circuit 8 generates a pulse signal with a smaller cycle than that of an output pulse from an encoder E. Output pulses from the pulse clock 81 are counted by a counter circuit 82 after the pulse signal output from the encoder E first rises before a sampling period terminates. A position or speed of the motor M is calculated at the operation part 11.

Title: Diode driver
Inventor: HISHINUMA SUSUMU
IPC: H03K17/795
Filed: 1981-12-28
Abstract: PURPOSE:To detect a fault easily with a simple circuit constitution, by providing a light emitting element and a photodetecting element at a current path and monitoring the output level of the photodetecting element. CONSTITUTION:When a signal of an L level is supplied to a terminal 3, a transistor TR4 is turned on to flow a forward bias current to a PIN diode 5. As a result, a high frequency is phase-shifted by a prescribed extent. In this case, a TR8 is turned off and no current flows to a light emitting element 14. Therefore the output of a photodetecting element 15 is set at an H level. When a signal of an H level is fed to the terminal 3, the TR4 is turned off with the TR8 turned on respectively. Then the adverse bias voltage is applied to the diode 5. In case the diode 5 is short-circuited, the current flows toward the TR8 from the earth side of the diode 5. Thus the element 14 glows. The output of a photocoupler is set at an L level to inform the generation of a fault.

Abstract: PURPOSE:To eliminate an omission displayed on the screen by sampling rectangular pulse-shaped chrominance components outputted from a computer, etc., after shaping a pulse signal to the waveform whose rise and fall parts are monotonously increased and decreased gradually.
