Inventor: RIZAWA HIRONORI
IPC: F15B11/02
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To simplify constitution of a hydraulic power unit. SOLUTION: When one oil feed discharge port 3a of a reversible type variable capacity type hydraulic pump 3 forms the discharge side, hydraulic oil discharged through an oil feed discharge port 3a drives an external actuator 1 to one side by releasing a pilot check valve 10A through hydraulic operation. Further, when the actuator is brought into a neutral position, the pilot check valve 10A is closed to reliably hold hydraulic oil in an external actuator 1. Further, when the other oil feed discharge port 3b forms the discharge side, hydraulic oil discharged from the oil feed discharge port 3b mechanically releases the pilot check valve 10A, and hydraulic oil in an external actuator 1 is sucked in the hydraulic pump 3 through one oil feed discharge port 3a and the external actuator 1 is driven to the other side.

IPC: H05K3/06
Filed: 1991-05-07
Abstract: PURPOSE:To obtain a uniform film in electrodeposition of resist on a printed wiring board by a constant current method by changing the current density when the impressed voltage is raised. CONSTITUTION:In electrodeposition of resist on a printed wiring board by a constant current method, the current density is changed when the impressed voltage is raised. The printed wiring board may used such resins as epoxy, phenol, unsaturated polyester, and silicone. For example, the surface of a glass cloth based epoxy resin laminate of a thickness of 1mm, is subjected to a resist electrodeposition on a current of 60mA/dm<2> for 40sec for the first and second stages and for 120 sec for the third.

Abstract: PURPOSE:To accurately detect a liquid level without generating an error, by a method wherein the lower part of a liquid level meter is supported by the support member extending from a vent tube and the lower end thereof is supported on the bottom surface of a container. CONSTITUTION:The lower part of a liquid level meter 10 is supported by the support member 8 extending from the vent tube 5 mounted on a fuel tank 1 and the lower end thereof is supported on the bottom surface 11 of the fuel tank 1. If the fuel tank 1 contracts or expands by the change in temp., the lower member 3 forming the bottom surface 11 rises or falls and a liquid level rises or falls and, in matching relation to this, the liquid level meter 10 also moves upward or downward. At this time, because the lower part of the liquid level meter 10 is supported by the support member 8 so as not to generate deflection to a horizontal direction, the liquid level meter 10 smoothly moves up and down. Therefore, even if the fuel tank contracts or expands, the liquid level can be accurately detected without generating an error.

Title: Facsimile communication system
Inventor: SUGIE MASATOSHI
IPC: H04N1/32
Filed: 1981-06-29
Abstract: PURPOSE:To completely prevent malfunction due to an echo, by controlling a frame length through the addition of a flag when a transmitting frame length is shorter than a preset value. CONSTITUTION:The maximum delay time of an echo is 2.4sec and it is a preamble time length. Thus, at the transmission of a frame, a preamble PRA, a frame FRM, and a flag FLG are transmitted and control is made so that the total transmission time length is 3.4sec or more. If the length of the FRM is 2.4sec or more, the addition of the FLG is unnecessary. Thus, the reception of the FRM is not posible before the time J being the end of transmission of the FLG, but since 3.4sec or more are already elapsed, the PRA passes through. At the time J, the succeeding FRM is fetched, but since the reception of the FRM is not made without the reception of the PRA, no echo signal is received. Thus, malfunction due to the echo can completely be prevented.

Title: Inverter
Inventor: MORI HARUYOSHI
IPC: H02J7/34
Filed: 1988-04-27
Abstract: PURPOSE:To reduce the size and the cost of an inverter, by connecting a reactor for suppressing ripple component in recharge current when a battery is recharged and being saturated with discharge current higher than a predetermined level when the battery is discharged in series with the battery. CONSTITUTION:A saturable reactor 11 is connected in series between a battery 10 and DC circuit in an inverter. When the battery 10 is subjected to floating recharge, the reactor 11 exhibits a predetermined inductance and the ripple component in recharge current is suppressed below an allowable level. Since DC circuit voltage drops upon power interruption, recharge current for the battery 10 decreases to invert the polarity of current flowing through the battery 10 so as to bring the battery 10 into discharging state. When the discharge current exceeds over the saturation level of the reactor 11, the reactor 11 is saturated thus bringing the inductance thereof to substantially zero. Consequently, the discharge current increases abruptly to the level of DC current flowing through the inverter 5 thus equalizing the DC circuit voltage to the battery voltage.
