IPC: B62D7/14
Filed: 1988-05-26
Abstract: PURPOSE:To improve the precision in the steering of rear wheels by installing a piping for introducing the pressurized fluid to a rear wheel input member side between a pump and a check valve set midway in a piping for introducing the fluid discharged from the pump to a front wheel servovalve side and installing a flow rate control valve for keeping constant the flow rate of the pressurized fluid into the piping. CONSTITUTION:In a four-wheel steering device, front and rear wheels are power-steered by the supply of the working fluid discharged from a tandem type feeding pump 37 which is driven by an engine into the power cylinders 15 and 26 through the servovalves 12 and 23 of the respective front and rear steering devices 10 and 20. In the rear wheel side servovalve 23, an input member 21 is turned by a rack-pinion mechanism 22 which is driven by the pressurized fluid passing through a four-port three-position selector valve 33. In this case, the flow rate control valves 43a and 43b equipped with each pressure compensation mechanism are interposed midway in a piping which is branched from the upstream side of a check valve 42 in a piping leading to a front wheel side servovalve 12 and leads to the selector valve 33, and the flow rate of the pressurized fluid for moving the input member 21 in reciprocation can be kept constant.

Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a cylindrical capacitor device having improved heat resistant property, while the increase of physical constitution is being suppressed, and to provide a manufacturing method of the capacitor device. SOLUTION: After housing an electrode assembly (also referred to as a capacitor element) in an almost cylinder-shaped case 1, the side face of the cylinder-shaped case 1 is caulked to the direction to the small diameter of the case. As a result, the close contacting property between the outer circumferential surface of the capacitor element and the inner circumferential surface of the cylindrical case can be markedly improved. Accordingly, the temperature of the capacitor element is dropped and the life the of the capacitor device can be prolonged, without increasing the physical constitution per capacitance due to the increase in heat radiating area and the lowering of power density.

Title: Gas sensor and gas detection method
Inventor: MACHIDA HIRONORI
IPC: G01N27/12
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To bring the resistance of a metal oxide semiconductor closer when CO and an inflammable gas are detected and to reduce temperature dependency when the CO is detected by composing an inner layer where Sb is added to SnO2 with the metal oxide semiconductor that is covered with an outer layer where no Sb is added to SnO2. SOLUTION: In a gas sensor 2, an inner layer 6 where Sb is added to SnO2 is provided on an insulation substrate 4 such as alumina, covering is made by an outer layer 8 using SnO2 where Sb is not added, thus composing a metal oxide semiconductor. By adding Sb to the inner layer 6, temperature dependency when detecting CO can be reduced. Also, by adding Sb only to the inner layer 6, sensitivity to an in-flammable gas (methane) cannot be reduced.  More specifically, a pair of electrodes 10 and 12 is connected to the inner layer 6, the temperature of the metal oxide semiconductor is periodically changed between high- temperature and low-temperature regions by a heater 14 that is provided on the reverse side of the insulation substrate 4, thus detecting methane and CO from resistance values at the high-temperature and low-temperature regions, respectively, and hence bringing the resistance values in both the detection closer.

Inventor: TAKAHASHI MINORU
IPC: H05B3/00
Filed: 1993-05-31
Abstract: PURPOSE:To provide an electrical heating apparatus capable of preventing temperature of a heater from being raised even when control means has any trouble. CONSTITUTION:When a relay output is erroneously operated upon a trouble of a sensor temperature input port of a microcomputer 5, and when temperatures of heaters H1, H2 detected by a sensor 9 are high, an L level signal is outputted from first and second relay output ports. Since the microcomputer 5 is not under overrunning in itself, H and L level pulses are outputted from an overrunning detection output ports so that a capacitor C3 is charged with electricity. Once the heaters H1 and H2 are raised to 60 deg.C, an operational amplifier OP2 is inverted to output an L level whereby a transistor Q3 is switched on. Once the transistor Q3 is switched on to permit electric charges on the capacitor C3 to be discharged. As the capacitor 3 is discharged, no current is supplied from a relay power supply circuit 2 to relay coils Ry1L, Ry2L. Hereby, the relay contacts Ry1S, Ry2S are opened with the heaters H1, H2 being off to prevent the temperature from being excessively raised.

Abstract: PURPOSE:To prevent malfunction when a pulse leading timing of a set input signal and of a control output signal are coincident by giving a reset release pulse signal to a control circuit and a 3-input NAND gate. CONSTITUTION:An output pulse of a 3-input NAND 3 rises at the pulse leading of a reset input signal to reset a control circuit 4 and the output pulse of the control circuit 4 is arisen.
