Title: Control signal generating circuit
Inventor: ITO KUNIHARU
IPC: H03K5/153
Filed: 1986-09-12
Abstract: PURPOSE:To eliminate the need for an external switching signal by detecting an output potential level of the circuit charging/discharging by an input clock and switching the control signal by a signal from the circuit discriminating the input clock frequency. CONSTITUTION:With a clock level of an input terminal 1 is at L, a transistor (TR) 4 is turned on, a connecting point 6 reaches an H level to charge a capacitor 7. With the clock reaching H, a TR 3 is turned on to discharge the capacitor 7 through a resistor 5. When the period of the clock is short, the level of the clock goes to L before the discharge of the capacitor 7 is finished, an inverter 8 keeps outputting at the L level and the output of a FF 9 remains at the L level. When the period of clock is long, the connecting point 6 goes to L by discharge and the output of the inverter 8 and the FF 9 output an H. A control signal switching circuit 11 switches the control signal when the clock frequency is high and low automatically depending on the L or H level of the output of the FF 9 to give an output 12. Thus, no external switching signal is required.

Title: Motor driven valve
Inventor: YAMAGUCHI MASAKI
IPC: F16K31/04
Filed: 1986-09-12
Abstract: PURPOSE:To enable keeping a sealed condition easily between a valve chamber system and an atmospheric pressure system by providing a valve rubber seat having a capped internal thread for gearing with the external thread of a valve spindle, and an O-ring seal between a fixed foundation and the valve spindle. CONSTITUTION:A valve spindle 1 turns and a valve rubber seat 3 tends to turn concurrently when a motor 2 has been electrically energized. The valve rubber seat 3, however, is prevented from turning by a guide (e) and the rotary motion thereof is converted into linear motion via a screw part (a). In an open valve condition, an O-ring seal 9 is fitted between the valve spindle 1 and a fixed foundation 5, thereby sealing a valve chamber. In a close valve condition, the screw part (a) is open only for the system of the valve chamber and it is unnecessary to close a gap between internal and external threads. Consequently, a thread of fluid can be separated with a valve rubber 4 and a valve seat (b).
