Title: Water supply pipe
Inventor: FUKUZAWA SOICHI
IPC: F16K31/40
Filed: 1988-07-22
Abstract: PURPOSE:To suppress the water hammer action by gently closing a diaphragm valve by opening and closing a pilot valve plural times in a short period by the processes from the perfect opening to the perfect closure when the diaphragm valve is to be closed. CONSTITUTION:A diaphragm valve 1 having an extraction hole 13 and an orifice 10 is arranged oppositely to a valve seat 28 formed between an upstream side flow passage 27 and downstream side flow passage 29. A pilot valve 14 installed at the top edge of a plunger 15 is arranged oppositely to the orifice 10. When a solenoid 18 is put into electric conduction, the plunger 15 rises, and the pilot valve 14 opens the orifice 10, and the pressure of a back pressure chamber 25 lowers, and the diaphragm valve 1 is opened. When the electric conduction of the solenoid valve 18 is suspended, the pilot valve 14 closes the orifice 10, and the pressure of the back pressure chamber 25 is increased to close the diaphragm valve 1. When the valve is closed, the pilot valve is opened and closed plural times in a short period, and the diaphragm valve is closed gently.

Title: Variable resistance circuit
Inventor: KIKUCHI HIDEO
IPC: H03H7/24
Filed: 1983-09-30
Abstract: PURPOSE:To attain the variation of resistance value over a wide range by switching plural MOS transistors with a switching means according to the resistance value to be obtained. CONSTITUTION:The MOS transistors (TR) 1 and 2 which are used in accordance with the desired time when the charging voltage Vp of a capacitor 4 is discharged are switched by means of a switch 3. When the discharging is desired for the electric charge of the capacitor 4 in an extremely short time, the switch 3 is connected to the source side of the TR1 for use of this TR1 having large (gm). Then the TR1 is selected by the switch 3 when the discharging of the capacitor 4 is desired in a little longer time. Thus the gate voltage of the TR1 is reduced. In this case, the resistance value is reduced less than the preceding time. When the long-time discharging is desired and at the same time a curve approximate to a discharge curve obtained with use of a linear resistance is desired, the switch 3 selects the TR2 of smaller (gm). Furthermore the ideal discharge characteristics can be obtained with use of many MOSTRs.

Title: Semiconductor circuit device
Inventor: KUNITOKI TADAYOSHI
IPC: H03F3/34
Filed: 1983-09-30
Abstract: PURPOSE:To obtain a high resistance with a small area by using a circuit which keeps an ON state of a transistor with high resistance. CONSTITUTION:The drain and the gate of a transistor (TR) 7 are short-circuited and connected to the gate of a TR6 via a resistance element 5. Both TR6 and TR7 which are produced in the same process use a back gate in common with each other. The TR7 is kept on as long as a current flows to both the element 5 and the TR7. This ON state of the TR7 is always obtained by supplying the voltage higher than that obtained between the gate and the source of the TR7 between the gate and the source of the TR6. The level of a connection node 63 is higher than that of a connection node 72 when the consideration is given to the voltage drop owing to a current flow. In other words, the gate-source voltage of the TR7 is higher than that of the TR6. Thus the TR6 is kept on. In this way, the production of a high resistance is attained with a small area.
