Filed: 1983-02-17
Abstract: PURPOSE:To obtain a composite switching circuit which has no drop in output signal power even when there is no instantaneous wave stop and one input signal system is disconnected at the same time, by using two equal power distributor, two output switches, and one equal power mixer in combination. CONSTITUTION:The input electric power of the 1st system impressed to an input terminal 1 is distributed equally by an equal power distributor 6; one distribution output is connected to a switch 8 and the other is connected to a switch 9. Similarly, the input electric power of the 2nd system impressed to an input signal terminal 2 is distributed equally by an equal power distributor 7; one distribution output is connected to the switch 8 and the other is connected to the switch 9. The outputs of the switches 8 and 9 are connected to the equal power composer 10. Consequently, the composite switching circuit has no drop in output signal power even when there is no instantaneous wave stop and one input signal is ceased at the same time.

Abstract: PURPOSE:To remove the influence of the direction incidence of radiation on a photodiode even in such a case and to take a measurement with high accuracy by selecting only the output waveform of the photodiode by a waveform discriminating circuit and measuring a dose. CONSTITUTION:The photodiode 21 of this device converts light pulses outputted by a scintillator 22 photoelectrically and also senses the X ray and gamma ray which are incident directly on the photodiode 21.

Title: Centrifuge
Inventor: SEKIZAWA KAZUYOSHI
IPC: F04D15/00
Filed: 1979-03-02
Abstract: PURPOSE: To facilitate change in rotational speed of centrifuge motor to a specified value by use of a motor speed detector circuit and a circuit generating a signal corresponding to the speed.  
     CONSTITUTION: A speed detector circuit 8 emits a square wave whose frequency is proportional to the rotational speed of motor 3. The square wave passes through a Schmitt circuit 9 and enters F-V converter 10, where it is converted to a voltage signal (j) proportional to the rotational speed, and the (j) is added to the reference voltage V 1  as minus value. This reduces input signal K for a differential amplifier 16 to cause the output to be converted from negative to positive. At this time, a gate circuit 6 is controlled so that a control current (minus) passes through the gate circuit 6 via a fixed resistor 7 to cause the motor 3 to be rotated at a rotational speed corresponding to the reference voltage. This eliminates the conventional inconvenience to change motor winding, and provides a means to allow a switching method to rotate the motor at specified multiple rotational speeds.
