Filed: 1991-02-08
Abstract: PURPOSE:To produce a sintered body containing a shaped part having been hitherto impossible to form except by means of machining by molding a powdery material of metal, ceramics, etc., by an injection molding method. CONSTITUTION:A powdery material, to which flowability is provided by a binder, is injected into a metal mold cavity where a previously formed core 4 is inserted and installed in the prescribed part, by which a molded body 5 where a main body 3 of molded part and the core 4 are integrated is prepared. Subsequently, the above core 4 is removed by means of melting by heating or elution with a solvent, by which the molded body of the desired shape is prepared. This molded body is passed through degreasing and sintering stages, by which a sintered body is obtained. Further, as a material for the core, a substance whose softening temp. is not lower by >=50 deg.C than the injection temp. of the powdery material is used. By using the core which can be easily removed after molding, even a molded body having a shape difficult of mold removal can be produced.

Abstract: PURPOSE:To ensure the protection for dv/dt by using one light emitting element so as to apply electrooptic signal conversion to a voltage proportional to a forward voltage of each optical thyrister for each thyristor and sending the result through one optical fiber in case of the transmission of an optical signal through the detection of the said voltage and the event of the dv/dt exceeding the specified value. CONSTITUTION:A series circuit comprising of a capacitor C, connected in parallel across an optical thyristor element Th a Zener diode ZD and a resistor R2 connected in parallel with a series circuit of a LED is a circuit to detect dv/dt across the optical thyristor element Th. Then a voltage proportional to the dv/dt appears across the resistor R2, and if the voltage exceeds a voltage depending on the constant voltage characteristic of the ZD, a current flows to the LED, from which an optical signal is generated. Both optical signals are sent to a control circuit CON placed on ground through one fiber and the signal is divided into a forward voltage detection signal or a dv/dt detection on the difference of the di/dt of the optoelectric conversion element placed on ground. Thus, the signal is distinguished by one fiber and proper protection is applied.

IPC: C22C9/00
Filed: 1983-03-10
Abstract: PURPOSE:To provide the titled copper alloy excellent in heat conductivity and heat resistance, obtained by adding Te and Sn or In to pure copper in a specific composition amount. CONSTITUTION:A Cu-alloy contains, on a wt. basis, 20-150ppm of Te and 20- 250ppm of Sn or In and comprises the remainder of Cu and inevitable impurities and is suitably used in the radiator fin of an automobile. In addition, the heat tranfer property and heat resistance thereof become excellent by the synergistic action of a proper amount of Te and Sn or In. The amounts to be added of the above mentioned componential elements are limited from such a reason that the enhancement of heat resistance is insufficient when Te is 20ppm or less while said heat resistance is enhanced when Te exceeds 150ppm but heat conductivity and processebility is lowered and Sn or In acts synergistically along with Te but the effect thereof becomes low when out of the above mentioned composition range. In addition, in the above mentioned copper alloy, O-content is desirably suppressed to about 100ppm or less.

Abstract: PURPOSE:To execute precharge operation only with a selected column line and to reduce energy consumption by executing the precharge operation to the column line through a column selecting circuit. CONSTITUTION:A memory is composed of a memory cell array, for which plural memory cells are arranged in a matrix shape, a column selecting circuit to selectively connect the column line to a common data line in correspondence to the outputs of the column line, in which data are read, and a column decoder and a precharge circuit to precharge the column line through this column selecting circuit.
