Title: Pressure balance valve for piston vacuum pump
Inventor: YOKOI KOUMEI
IPC: F04B37/14
Filed: 1983-07-22
Abstract: PURPOSE:To simplify the structure considerably by opening/closing a pressure balance valve for feeding pressure into a cylinder by means of piston itself. CONSTITUTION:Only the foot rod 18 of a pressure balance valve 16 for closing the valve port 15 through resilience is projected to a cylinder 2 without projecting a pressure balance sleeve 10 fixed to the delivery chamber 9 side. A press chip 20 for pushing the foot rod 18 to open said valve 15 near the final stage of compression stroke is provided on the piston head. Consequently, only the pressure balance valve 16 is provided movably to function it directly by means of the press chip 20 of piston 3. Since a mechanism for driving said valve 16 is not required independently, the structure can be simplified considerably. Also since the sleeve 10 is not movable, occurrence of faults can be reduced.

Title: Subscriber's line testing system for telephone exchange system
Inventor: KIKUKAWA TAKAHIKO
IPC: H04M3/30
Filed: 1993-06-04
Abstract: PURPOSE:To provide a subscriber's line testing system for easily recognizing error at an operating terminal when the setting of an attenuator level is wrong. CONSTITUTION:A test is instructed from an operating terminal 9 through an exchange 4 to a subscriber's line testing device 5. The subscriber's line testing device 5, which receives the instruction, receives an attenuator level set value 11 of a subscriber circuit from the exchange, transmits the received attenuator level set value to the operating terminal by driving a set value transmitting means and displays it. In this case, the set value transmitting means transmits an attenuator level set value 12 through a path set for the exchange to transmit the test instruction from the operating terminal to the subscriber's line testing device. Therefore, the operating terminal can immediately recognize the attenuator level set value set by the exchange.

Title: Ring follower gate
Inventor: MATSUMURA HIROSHI
IPC: E02B7/54
Filed: 1994-06-17
Abstract: PURPOSE:To close an opening section positively when a gate is closed completely by mounting door-body wedges with downward inclined planes on both side sections in the cross direction of a door body and installing door-frame wedges with upward inclined planes onto the inner circumferential surface of a door frame. CONSTITUTION:When a ring follower gate is closed, the downward inclined planes 16a of door-body wedges 16 are abutted against the upward inclined planes 17a of door-frame wedges 17 when a door body 15 is slid in the downward direction and the opening of a door frame 12 is closed completely by the closing section 13 of the door body 15. Since the door body 15 is pushed in the direction of the sheet ring of the door frame 12 by reaction at that time, the sheet surface of the door body 15 is brought into press-contact with the sheet ring of the door frame 12, thus positively closing an opening section.

Title: Signal receiver, its method and served medium
Inventor: TAJIMA YOICHI
IPC: H04B10/112
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To allow a signal receiver to eliminate a noise component superimposed on a received signal. SOLUTION: An LPF 27 demodulates a PWM signal received via an RS FF circuit 26. An LPF 29 demodulates a synchronizing signal outputted from a monostable multivibrator 25. A noise reduction circuit 28 subtracts an output of the LPF 29 from an output of the LPF 27 to eliminate the noise component included in the output of the LPF 27. Thus, the noise component in the signal can surely be eliminated with a simple configuration.

Abstract: PURPOSE:To improve engine performance by increasing a pressure, by a method wherein, during high speed high load running, a check valve is opened to control a fuel pressure, safety operation is performed at a pressure lower than the allowable maximum value of a pump, and meanwhile during middle speed middle load running, an injection pressure is increased. CONSTITUTION:Since, while, during low speed low load running, a main port 8 is closed by an outer peripheral surface 3c of a plunger 3, a subport 9 is also closed by the outer peripheral surface 3c of the subport 9, a maximum injection pressure is increased with the increase in the number of revolutions. Meanwhile, during middle speed middle load running, at the final stage of injection where the main port 8 is closed by the outer peripheral surface 3c of the plunger, the subport 9 is positioned facing a subreed 17, and a fuel pressure flows to the subport 9 through a notch 18. When, during high speed high load running, the number of revolutions is further increased, a check valve is opened, high pressure fuel from a pressurizing chamber flows through the subport 9 from the notch 18, and is discharged in a state to hold an allowable maximum pressure.

Abstract: PURPOSE:To reduce number of circuit components, to decrease the limit of an input dynamic range due to a power supply voltage and to attain the gain control of an output signal by applying coring operation with a limiter and a differential amplifier. CONSTITUTION:A level of an input signal VIN is shifted by a level VBE and the resulting signal is a signal (g).

The signal (g) is limited at a voltage width of VC1+VBE above the center level and a voltage width of VC2-VBE below the center level by the limiter 2 to be a signal (h). The differential amplifier 1 receives the signal (g), (h) at their inputs and the difference is outputted as a signal (i) via resistor RL. As a result, the signal (i) results from coring the signal (g) above the center level with a voltage width VC1+VBE and a voltage width of VC2-VBE below the center level.
