Patent JP-H0411109-A (JP)
Title: Liquid pressure water-regulator
Inventor: ARAGATA KUNIKAZU
IPC: E03B3/32
Filed: 1990-04-27
Abstract: PURPOSE:To minimize the difference in water level between the upper limit and the lower limit by communicating the upper and lower parts in a cylinder to a liquid pressure source or to outside air through a change-over valve, and by interlocking a float with the change-over valve through a rotating cross arm. CONSTITUTION:The water level of a pond is detected by upper and lower floats 46, 47, while a change-over valve 31 connected with a float piston 28 is operated through a rotating cross arm 41 by mean of the elevation of the upper and lower floats 46, 47. A liquid is flown into one side of the inside of a cylinder 19, and a moving valve 18 is moved by applying pressure to the float piston 28, and an opening is thus adjusted. When the elevation of the floats 46, 47 once starts, the increasing or decreasing value of buoyancy following this is offset by the eccentric power of an unbalance weight 51, and the elevating movement of the floats 46, 47 is promptly finished. The moving valve 18 is operated by water pressure without being affected by water level, and a water- regulator can thus be operated accurately.

Title: Fuel injection unit
Inventor: ISHIKAWA HIDEAKI
IPC: F02D41/36
Filed: 1985-05-29
Abstract: PURPOSE:To feed fuel under stable and precision control with minimal power consumption by setting a current control circuit for injectors which controls current to each injector through changing the reference voltage for current control in accordance with injection patterns. CONSTITUTION:When the reference signal B for crank angle sensor is input into I/O interface 2, a fuel injection signal is input from CPU1 into the clear end of the D type flip-flop 4 and into a fuel injection current control circuit 6. The AND product of the output Q from D-FF4 and the signal I from the control circuit 6 is transmitted to the base of transistors 7 to actuate each injector. The Q from D-FF4 is input into a reference voltage conversion circuit 10, of which output signal is input into the fuel injection current control circuit 6 to vary the reference voltage in accordance with every possible injection pattern. In this way, fuel is fed under stable and precision control with minimal power consumption for injectors.

Title: Semiconductor-implanted integrated logic circuit
Inventor: TABATA TERUO
IPC: H01L27/082
Filed: 1986-05-19
Abstract: PURPOSE:To improve the integration of a semiconductorimplanted integrated logic circuit by so forming a separating regin as to reach to the surface of an epitaxial layer upward from the surface of a substrate. CONSTITUTION:A P<+> type separating region 24 formed to reach to the surface of an epitaxial layer 22 upward from the surface of a substrate 21 and a P-type active base regin 26 simultaneously formed driven-in the region 24 are provided. Since the region 24 is so formed as to reach to the layer 22 upward from the substrate 21, the lateral diffusion of the region 24 on the layer 22 is extremely small, and the surface occupying area of the region 24 is accordingly slightly larger than the area of a diffusion window. Thus, the integration can be largely improved.

Since the vibrating unit 3 is supported at a position spaced from the wall of the liquid chamber 4, the unit can be displaced by large amount even when the chamber 4 is reduced in size. In addition, at least a part of the chamber 4 is constituted of a curved surface form (e.g., tubular form) flexible member, the change in volume is large even when the chamber 4 is small in size. Accordingly, a reduction in size and integration can be easily accomplished.

Filed: 1994-05-27
Abstract: PURPOSE:To uniformly supply water and uniformly exhaust reaction water by forming a gas separator having small diameter pores and large diameter pores with a hydrophilic porous body. CONSTITUTION:When hydrogen serving as fuel and water (gaseous or liquid state) for humidification are supplied from the upper part of a gas separator 1B, since the separator 1B made of a hydrophilic porous body has an average pore diameter of about 10-100mum but actually has smaller diameter pores and larger diameter pores than the average pore diameter as pore diameter distribution, the supplied water is filled in the small diameter pores as liquid water by capillary condensation, and distributed all over the surface of a hydrogen electrode side electrode diffusion layer 3A of a cell 7 to humidify a hydrogen electrode. Since the larger diameter pores in the separator 1B have no condensed water and are left as continuous pores, hydrogen-containing wet gases freely move and diffuse inside the pores, and hydrogen serving as fuel is distributed all over the surface of the hydrogen electrode side electrode diffusion layer.

Filed: 1984-06-05
Abstract: PURPOSE:To turn a propeller safely and certainly by installing a means for transmitting a proper instruction to a propeller turning hydraulic mechanism when an advance/retreat switching level is sharply switched. CONSTITUTION:One among the normally opened switches 28-1 and 28-2 driven by the output corresponding to the rightward and leftward turnings is closed, and one-side output between amplifiers 27-1 and 27-2 is transmitted to a hydraulic mechanism. For instance, in case of leftward turn, the switch 28-1 is closed, and the positive potential of the output of the calculation amplifier 27-2 is applied into a power amplifier 25-3, and in case of rightward turn, the switch 28-2 is closed and the negative potential of the calculation amplifier 27-1 is applied. Since the positive or the negative potential has a prescribed magnitude and acts in the direction corresponding to a prescribed movement of an advance/retreat switching lever, the direction of turn by the hydraulic mechanism can be determined correctly. Since the normally closed switch 24 and the normally opened switch 28 return to the ordinary state after the lapse of a prescribed time, the normal shift-angle of 180 deg. can be obtained by the amplifiers 25-1 and 25-2, and the turn is brought into stop at that position.
