Patent JP-S59183529-A (JP)
Title: Signal gate circuit
Inventor: KANO MITSUYOSHI
IPC: H03K17/74
Filed: 1983-04-04
Abstract: PURPOSE:To prevent the loss at signal passing and also the generation of abnormal resonance by providing a circuit feeding back a signal through an auxiliary diode opposite to a signal path via a capacitor and a resistor from a connecting point of two diodes in the same polarity inserted into the signal passing circuit. CONSTITUTION:A signal is fed back from a connecting point of the two diodes D1, D2 inserted into the signal passing line through the auxiliary diode D3 via the capacitor C2 and the resistor R2. The emitter of a transistor (TR) Q is connected to a negative power supply. When no control signal is applied to the TRQ, the collector and emitter are turned off and the diodes D1, D2 are made conductive. When the control signal is inputted to the TRQ, the diode D3 is conducted and the diodes D1, D2 are cut off. In selecting the resistor R2 to a value equivalent to nearly 100 times the forward resistance of the diode, the capacitance of the capacitor C2 is made independent of the loss and resonance. Thus, the loss and abnormal oscillation at the signal passing are prevented.

Inventor: KASAI SHIYOUTAROU
IPC: F04D7/04
Filed: 1978-05-19
Abstract: PURPOSE: To easily obtain dust collecting effect as well as to reduce price by integrally forming a dust collecting equipment and a blower, and utilizing the  centrifugal effect of an air flow coming out from a vane wheel, at the periphery of which a dust collecting casing is installed.  
     CONSTITUTION: A section of a main casing 13 at the periphery of a vane wheel 12 is expanded to form a dust collecting casing 17 in a shape of a spiral that complies with a rotational direction of the vane wheel 12. Dust contained in a coming- out fow from the vane wheel 12 enters in the dust collecting casing 17 and is collected due to the centrifugal force. While clean air is exhausted from a ring- shaped passage between the main casing 13 and an inner casing 14. With this integrally formed simple dust collecting casing 17 and a blower, dust collecting effect is easily obtained as well as the cost for the equipment is reduced because less installation area is required.
