PURPOSE:To generate efficiently a delay series having an optional delay characteristic with good operability, by setting a prescribed delay time by a microprocessor of a circuit to generate a delay series. CONSTITUTION:The titled generator consists mainly of a reference series generating circuit U1 generating a reference series m(k), an arithmetic circuit U2 performing a set operation such as a re...

PURPOSE:To recover automatically the stop of output for an electronic device, by detecting a hit of the output due to the break of a power supply of the electronic device having a microcomputer and then controlling the microcomputer which controls said electronic device. CONSTITUTION:A synthesizer 8' consists of a synthesizer circuit 5 containing a microcomputer 4, and the output of the synthesize...

A self-supporting composite comprised of a mass of diamond and/or cubic boron nitride crystals coated with elemental non-diamond carbon in contact with a substrate is infiltrated by fluid silicon producing a like-shaped composite of a polycrystalline body phase integrally bonded to a substrate supporting phase. The composite is useful as an abrasive, cutting tool, nozzle or other wear-resistant pa...

PURPOSE:To rapidly continue a motor in operation by disconnecting a defective bank from the circuit when the defect occurs in one bank of multiplexing configuration, decreasing the speed reference signal, and setting the motor current value to the remaining power converter capacity or lower. CONSTITUTION:AC commercial power is supplied from an input switch 1 through an input transformer 2, rectifi...

The invention relates to a device including a container charged with a water treatment material and a perfume material, intended to be partially immersed in the water in a flushing tank of a toilet fitting whereupon to deliver water treatment material in solution to the water in the tank and perfume to the surrounding atmosphere. The device is essentially different from prior art devices in that w...

PURPOSE:To match the size of pellet supporting metal plate to a larger pellet among at least two pellets and realize reduction in size of package by assembling pellets of different elements on both sides of pellet supporting metal plate. CONSTITUTION:A pellet 1 forming a GaAs FET is connected, at the bottom surface formed as an electrode, to the surface of pellet supporting metal plate 2a on which...

An exhaust pressure responsive flow control valve is disposed in a secondary air supply passageway leading from the atmosphere to engine exhaust system. The valve has a valve member of a material which is movable by influence of magnetic fields and an electromagnet means for urging the valve member toward a valve closed position upon passing of electric current therethrough. First circuit means is...
