    摘要: In a semiconductor device such as a thin film transistor a semiconductor region is formed and an insulating film is formed on the semiconductor region to have a contact hole extending to the semiconductor region. An electrically conductive metal layer is formed of aluminum to fill the contact hole. An electrically conductive protection layer is formed on the metal layer to prevent oxidation of the metal layer during manufacturing of the semiconductor device. Material of the protection layer is more difficult to be oxidized than aluminum. A transparent electrode is formed on the protection layer such that the electrode is electrically connected to the semiconductor region. The protection layer may be formed of titanium or a laminate layer of a titanium layer and a titanium nitride layer.

    摘要: A semiconductor device which achieves high-speed access and prevents the latch-up for any power inputting sequence by a plurality of power sources is disclosed. Where the chip voltage VDD is earlier inputted, an N well bias circuit 9 and a P well bias circuit 10 are activated, and an N-type well 12 and a P-type well 13 are biased respectively. After that, although the interface voltage VDDQ is inputted, the latch-up is not generated. On the other hand, where the interface voltage VDDQ is earlier inputted to a terminal 8, the N well bias circuit 9 and the P well bias circuit 10 are activated through a bypass circuit 15, and the N-type well 12 and the P-type well 13 are biased. Accordingly, although the chip voltage VDD is inputted after that, the latch-up is not generated.

    摘要: A suspension system for a vehicle which has a hydraulic cylinder that extends and retracts in accordance with a change in the distance between a vehicle body and an axle to vary the volumetric capacity of a working chamber defined therein, an accumulator connected to the working chamber in the hydraulic cylinder, a control valve controlling the flow rate of oil charged into and discharged from the accumulator and the hydraulic cylinder, and a vehicle level sensor detecting a change in the above-described distance. The suspension system further has a control unit that controls the control valve, on the basis of a flow control signal obtained by multiplying the detected signal from the vehicle level sensor by an amplification factor, so as to restore the vehicle to a neutral state. The control unit is arranged to increase the amplification factor when the amount of the extension or retraction of the hydraulic cylinder is close to the extent of the full stroke thereof. When the vehicle is running on a normal road surface, the suspension system absorbs any changes in the road surface, thereby stably maintaining the attitude of the vehicle body, and in the case of large irregularities, it is possible to prevent full rebound or full bump which would otherwise occur when the hydraulic cylinder performs a full-stroke operation.

    摘要: In a closed type thermal power generation plant, the fuel is supplied in the combustor and burnt therein in the presence of oxygen, instead of air. The combustion gas mainly including water and carbon dioxide is delivered from the combustor into the turbine. A turbine exhaust gas is fed into the waste heat boiler to carry out heat exchanging operation therein and an exhaust gas mainly including water component and carbon dioxide from the waste heat boiler is fed into the condenser. The gas component mainly including the carbon dioxide is separated from the condensate in the water-gas separator and may be fed into the combustor in a compressed state, or the separated gas component may be recovered externally to the plant without emitting the same into the atmosphere. The separated condensate is fed into the waste heat boiler to be subjected to heat exchanging operation therein to generate superheated steam which is to be fed into the combustor, or may be recovered externally.Further, a steam turbine may be connected to the waste heat boiler and generator. A condensor may then be connected to the steam turbine and waste heat boiler so that the steam turbine, condenser and waste heat boiler constitute a closed cycle.
