Title: Logical simulation method
Inventor: URANO YOSHINORI
IPC: G06F19/00
Filed: 1988-02-02
Abstract: PURPOSE:To execute a logical simulation of high efficiency which does not execute an unnecessary processing by propagating a signal to an input side from an output side of a circuit which becomes an object of the logical simulation, checking from the input side whether this signal is being propagated or not and re-forming a component for exerting no influence on an external output of the circuit. CONSTITUTION:An arbitrary signal is propagated to an input side from an output side of a circuit which has been stored on a memory of a computer as an object of a logical simulation. Subsequently, whether this signal is being propagated to a component or not to the output side from the input side is checked, and by removing the component to which the signal is not propagated, a circuit which does not contain the component having no output is re-formed. In such a way, a logical simulation of high efficiency in which an unnecessary processing is not executed can be executed.

Title: Dc stabilized power unit
Inventor: YASHIRO YUJI
IPC: G05F1/56
Filed: 1991-02-18
Abstract: PURPOSE:To reduce the fluctuation of a DC stabilized power unit by superposing the ripples on each other and at the same time eliminating the output halt section of the output voltage at start up to the DC input voltage having a slow rise. CONSTITUTION:An error amplifier performs the control in order to set the error at zero between the reference voltage of a reference voltage circuit and the detection voltage of the output voltage and to fix the output voltage at an output set voltage corresponding to the reference voltage. A constant current source circuit which supplies the driving power to the reference voltage circuit and the error amplifier is started by a start-up circuit when the input voltage reaches a start voltage lower than the output set voltage. A stop voltage lower than the start voltage is set to the start-up circuit so as to secure the hysteresis characteristic. Therefore the start-up circuit never stops the drive of the constant current circuit as long as the input voltage including the ripples and also rising and falling drops less than the stop voltage level at start up. Thus, the output halt section of the output voltage is never produced.

Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To enable inhibition of heat build-up of resin by making front shape of a orthogonal section of a transmission part screw flight into a right angle and rear shape into a curved surface. SOLUTION: A screw flight 2B of a screw 2A in a transmission part has front shape of a right-angled face L on the orthogonal section with respect to the screw flight 2B direction, and rear shape of curved face. Each of the screw flights 2B is separated axially for increasing a gap of an intermeshed part 2C between each screw 2A. As a result, resin is extruded through a front face of the screw flight 2B and moved toward downstream side. Since a large gap is formed between the front face L of one screw flight 2B and a rear face R, of the other screw flight 2B, heat build-up of resin in a transmission area is inhibited.
