Title: Motor driven vehicle with battery as power source
Inventor: YOKOI SATORU
IPC: B60L11/18
Filed: 1985-09-12
Abstract: PURPOSE:To reduce the steps of maintenance of a battery by regeneratively braking a driving motor at a stopping time to charge the battery. CONSTITUTION:A speed controller 11 calculates a speed signal (e) and a speed command signal (v), and a digital controller/phase controller 13 further converts it into a signal for deciding the output waveform of an inverter 6. After the current signal (i) of a motor 1 is applied as a negative feedback signal, a PWM power amplifier 15 applies a conduction signal to the base of a transistor 16 in the inverter 6 to control the speed of the motor 1. When an unmanned transport vehicle is stopped, the speed command signal (v) for applying a speed smaller than the speed at that time is applied. Thus, the motor 1 becomes a generator to convert the kinetic energy of the entire vehicle to electric power to charge a battery 4.

Title: Amplifier circuit for radiation detection
Inventor: FUJIMOTO HIDETOSHI
IPC: H03K5/02
Filed: 1986-08-27
Abstract: PURPOSE:To reduce a power consumption without reducing a detecting sensitivity by operating a current source circuit in response to the detection signal of a radiation detector and adding a current source starting and stopping circuit for generating a constant current to the current source circuit only while the detection signal pulses are present. CONSTITUTION:In an amplifier circuit for amplifying a pulse-like detection signal from a radiation detector 1, a current source circuit 10 generates a constant current with a prescribed value. Receiving the detection signal from the detector 1, a current switch circuit 20 outputs the current from the current source circuit 10 while the detection signal pulses are present. Receiving the output current from the circuit 20, an output circuit 30 integrates the value o the output current and outputs it as amplified output signals. A current source starting and stopping circuit 40 actuates the current source circuit 10 in response to the detection signal from the detector 1 and generates a low current in the current source circuit 10 only while the detection signal pulses are present. Thus, by stopping the generation of a useless constant electric power in the current source circuit 10 when no detection signal from the detector 1 reaches, the power consumption of the amplifier circuit can be sharply reduced.
