Title: Hot water feeder
Inventor: OKADA SADAO
IPC: F24H1/00
Filed: 1990-04-05
Abstract: PURPOSE:To enable a positive recovery of water accumulated in a back-flow preventing device to be attained by a method wherein an opening or closing valve is disposed between a pump and a bath tub, a discharging port is disposed at a bottom part of a hopper and the discharging port is connected to an absorbing device of the pump together with the downstream side of the second check valve through a solenoid valve. CONSTITUTION:A surrounding air discharging port of a valve chamber between the first check valve 10 and the second check valve 30 is closed by an opening or closing valve as a pressure in the valve chamber is increased, the second check valve 20 is opened by a pressure of the hot water, so that the hot water is supplied to the bath tub B. In turn, water discharged from the surrounding air releasing port is stored in a hopper 20. As the hot water supply is stopped, the water is also accumulated in the valve chamber. A discharging port is disposed at the bottom part of the hopper 20 and the discharging port is connected to a suction side of the pump 104 together with the downstream side of the second check valve 30 through a solenoid valve 23. An opening or closing valve 108 is disposed between the suction side of the pump and the bath tub B. Accordingly, if the opening or closing valve 108 and the solenoid valve 23 are closed and the pump 104 is operated, the second check valve 30 is opened and the water accumulated in the valve chamber is sucked out into the bath tub B and if the solenoid valve 23 is opened, the water in the hopper 20 is sucked out into the bath tub B.

Title: Air-fuel ratio controller
Inventor: WATAYA SEISHI
IPC: F02D41/00
Filed: 1986-04-18
Abstract: PURPOSE:To prevent the fluctuation in torque, by suspending the feedback control of the air-fuel ratio and performing the open-loop control thereof when the width of fluctuation in a corrected value in the feedback control has been larger than a prescribed magnitude for over a prescribed time. CONSTITUTION:Detection signals from a pressure sensor 6, a rotation sensor 7, a water temperature sensor 8 and so forth, which correspond to the operating parameters of an engine 1, are read in the microprocessor 113 of a controller 11 so that a basic fuel injection quantity is calculated. The result of the calculation is corrected on the basis of the output from an O2 sensor 9 serving as an air-fuel ratio sensor. An injector 4 is driven depending on the result of the correction to feed a prescribed quantity of fuel to the engine 1. When the width of fluctuation in the corrected value has been larger than a prescribed magnitude for over a prescribed time, the O2 sensor 9 is judged to be abnormal. After that, the corrected value is fixed, and open-loop control is performed.

Title: Amplifier circuit
Inventor: DOUSEKI TAKAKUNI
IPC: H03K19/0175
Filed: 1990-04-06
Abstract: PURPOSE:To decrease a DC current and the delay time of an amplifier circuit by adding a feedback circuit to a 1st inverter and an emitter follower circuit to a 2nd inverter in a cascade connection inverter circuit. CONSTITUTION:When an input signal VIN changes from a low level to a high level, for example, an output V2 rises by a bipolar transistor(TR) Q1 in a 2nd inverter 4. When the V2 rises, a MOS TR M2 accelerates extraction of charge and the output V1 of a 1st inverter 3 is decreased. When the level V1 reaches a logic threshold level or below, the output V2 is inverted and the output level of each inverter is confirmed. Since the input signal goes to a high level after the output level is confirmed, a pMOS TR M1 is not energized and no DC current flows. Thus, low power consumption is attained and the delay time is reduced by an emitter follower circuit and a feedback circuit.

Title: Light amplifying parts
Inventor: MIKAWA IZUMI
IPC: H01S5/00
Filed: 1990-04-09
Abstract: PURPOSE:To use pump light having an arbitrary wavelength to perform light amplification by narrowing a part of an optical fiber and arranging a refractive index matching material including one or more kinds of light amplifying element around this part. CONSTITUTION:A refractive index matching material 3 to which light amplifying elements are added is arranged around an area where the optical fiber is narrowed. Propagated light is leaked from a core 1 to a clad 2 according as approaching the area L and is propagated in all of the clad and the matching material 3 in the area L. At this time, the wave is guided by the refractive index difference between the clad 2 and the matching material 3 surrounding this clad, and it is coupled to the core 1 again after passing the area L. Consequently, light is amplified by the action of the pump light upon light amplifying elements added to the matching material 3 when the propagated light consists of the pump light and signal light, and therefore, the matching material 3 is selected to amplify the light with arbitrary pump light.

Accordingly, the first joint 8 of each leg is corresponded with the walking direction of a moving body before moving is started, and walking can be performed at the time of moving only by controlling the second and third joints 9 and 10 of each standing leg 17. Owing to this constitution, walking can be performed without the computation for a control of the first joint and for corrections required by the control of relative actions among respective joints in the direction normal to the walking direction, and furthermore in the horizontal direction and the like for reducing the loading of a computer used for the control of systems. Furthermore, squeaking of legs and a body, stress concentration, strain, and twist which are resulted from errors in control for each leg can be reduced thereby eliminating the dragging phenomenon of standing legs caused by said factors.
