Title: Semiconductor integrated circuit device
Inventor: MATSUURA NOBUMI
IPC: G11C11/34
Filed: 1985-11-22
Abstract: PURPOSE:To improve the trackability of a power source voltage and to reduce power consumption by supplying a negative voltage formed by a capacitor through an FET controlled by a negative voltage generated complementary to the former voltage. CONSTITUTION:An inverter formed with P-type complementary FETs Q1 and Q2 and that formed with N-type complementary FETs Q3 and Q4 operate complementarily. When one electrode of the capacitor C1 connected to the FETs Q3 and Q4 with their outputs at L comes to L, a diode connection FET Q5 is turned off, and the other electrode C comes to a negative potential. An FET Q7 is turned on by the inverters Q1 and Q2 operating complementary to the inverter, the capacitor C2 connected to the inverter and the level L of a diode connection FET Q6, and the low potential of the electrode C is outputted as the back bias voltage of a substrate. With this constitution using the capacitor, the trackability of the power source voltage is improved, and the FET for controlling a negative voltage can transmit a negative potential back bias without loss. And power consumption can be reduced by making an oscillation frequency and capacitor capacity smaller.

Title: Flow passage valve
Inventor: SHIYOUJI MASANAO
IPC: G01F1/38
Filed: 1990-09-29
Abstract: PURPOSE:To prevent to transmit a sudden high pressure to the downstream side by dividing a valve chest into the upstream side and the downstream side by a diaphragm, and displacing the diaphragm to shut the tip of the main passage at the downstream side when a high pressure is applied suddenly to the main passage at the upstream side of both valve chests. CONSTITUTION:A valve chest 4 is divided into the upstream side chest 4a and the downstream side chest 4b by a diaphragm 6 provided crossing the valve chest 4. And the tip of the main flow passage 2a at the upstream side is led to the valve chest 4a at the upstream side, while the tip of the main flow passage 2b at the downstream side is led to the valve chest 4b at the downstream side. The tips of both main flow passages 2a and 2b are close to the diaphragm 6, and opposed each other at both sides of the diaphragm 6. The diaphragm 6 furnishes apertures 10 to pass the gas with no resistance opened at the area other than the area where the tips of both passages 2a and 2b are opposed. When a high pressure is applied from the upstream side suddenly, the diaphragm 6 is displaced by receiving the force of the gas, a rubber sheet 8 is attached closely to the tip of the downstream side main passage 2b, and the tip of the main flow passage 2b at the downstream side is closed.

Filed: 1987-10-19
Abstract: PURPOSE:To prevent the overrun fault of a data chain by comparing the data field length with the segment length of the data chain and inhibiting the execution of the final phase of the data transfer performed to an I/O processor until a count state is set for the next segment of the data chain in case the coincidence is obtained between said data field length and segment length. CONSTITUTION:The first data field length is set at a data counter 600. While the first segment length of a data chain is set at an I/O bus transfer counter 300. A data count comparing part 700 compares the count values of both counters 600 and 300 with each other and checks whether or not the coincidence is obtained between the segment length of the data chain and the data field length to be processed hereafter. If the coincidence is obtained between both lengths, the part 700 starts its action to always monitor the state of the counter 300 and waits until the final phase of the data transfer performed to an I/O processor via a signal line 1 is started.
