Title: Drive circuit for brushless motor
Inventor: NAKASE HIROMI
IPC: H02P6/20
Filed: 1986-06-19
Abstract: PURPOSE:To improve the starting operation of a motor by starting the motor from its stopping state by means of a motor drive circuit, and switching to a motor drive by a phase detection energizing circuit when the rotating speed of the motor exceeds a set speed. CONSTITUTION:Data for setting the starting speed variation of a motor 5 is stored in a memory circuit 9, and is set in a counter 8. A logic processor 7 inputs the output of the counter 8 at the time of starting and starts the motor 5 from its stopping state. When the rotating speed of the motor 5 exceeds a set speed, the processor 7 inputs the output of a comparator 6 and drives the motor by means of phase detection energization. When the stop of the motor 5 is detected by an output signal from a rotation detector 14 from the starting time, the processor 7 again starts the motor.

Title: Voltage control oscillating circuit
Inventor: IZAWA KAORU
IPC: H03K3/0231
Filed: 1982-08-20
Abstract: PURPOSE:To set easily both the lock range and the center frequency, by synthesizing the input voltage with a reference current after converting it into a current and using this current to charge and discharge a capacitor. CONSTITUTION:When a working current is applied from an input terminal 48, a constant current IO flows to a transistor TR58. At the same time, a current IO/n flows to a TR56. Then the voltage which is the same type as VCC/2 set by a voltage setting circuit 94 is applied to an input terminal 2. Thus the output current of a voltage/current converting circuit 27 is set at 0, and only the reference current IO flows to a TR68 of a constant current circuit 66 from the TR58. Then a capacitor 84 is charged by a current mirror effect. Then the terminal voltage of the capacitor 48 exceeds a certain level, an FF100 is set. Then a TR80 conducts to perform discharging. In such a way, the capacitor 84 is charged and discharged. As a result, the lock range can be easily set by changing the resistance ratio between resistances 62 and 64. At the same time, the center frequency is easily set by controlling the input current 48.
