  • Publication number: 20030218098
    Abstract: An airplane fuel supply system includes a wing fuel tank that is formed from a wing tip fuel tank having a wing tip fuel pump; a central fuel tank having a central fuel pump; and a wing root fuel tank having a wing root fuel pump. Fuel movement from the wing tip fuel tank to the central fuel tank is allowed by a flapper valve, and fuel movement from the central fuel tank to the wing root fuel tank is allowed by another flapper valve. When the fuel delivery volume of the wing tip fuel pump is represented by Vt, the fuel delivery volume of the central fuel pump is represented by Vc, the fuel delivery volume of the wing root fuel pump is represented by Vr, and the fuel delivery volume from a collector tank to the engine is represented by Ve, the fuel delivery volumes Vt, Vc, Vr, and Ve are set so as to satisfy the relationships Vr>Ve, Vt+Vc>Ve, and Vc<Ve. This can minimize the size of the fuel pumps for supplying fuel from the airplane wing fuel tank to the engine.

  • Patent number: 6599819
    Abstract: A gate electrode is formed in a partial area of the surface of a semiconductor substrate. Impurities of a first conductive type are implanted into the semiconductor substrate in areas on both sides of the gate electrode, by using the gate electrode as a mask. The implanted impurities are activated by applying a laser beam to the surface of the semiconductor substrate. Impurities to be used for threshold voltage control are implanted into the surface layer of the semiconductor substrate under the gate electrode, after the laser beam is applied. The impurities for threshold voltage control are activated by heating the semiconductor substrate. A semiconductor device is provided having a low parasitic resistance of source/drain regions and a desired threshold voltage hard to be lowered.

  • Patent number: 6490697
    Abstract: The present invention enables reliable shift to a fail-safe processing upon detection of failure by RAM diagnosis. To this end, the diagnosis result of the RAM diagnosis is doubly stored, as flags, into mutually different two addresses of the RAM; and a fail-safe processing is conducted based on the doubly stored diagnosis result flags when at least one of the flags indicates existence of failure. Otherwise, the diagnosis result of the RAM diagnosis is stored, as a flag, into a predetermined register; and a fail-safe processing is conduced based on the diagnosis result flag stored in the register such that the fail-safe processing is conducted when the flag indicates existence of failure.

  • Publication number: 20020157882
    Abstract: A hybrid vehicle is provided with an internal combustion engine as a power source and an electric motor. The electric motor is used to charge the high-voltage battery. Charge/discharge control of the high-voltage battery and an idle-stop control can be performed, taking into account battery deterioration. For this purpose, the internal resistance R is detected as a degree of deterioration in the high-voltage battery. When the internal resistance R is less than a predetermined resistance R1, a threshold value of a state of charge (SOC) of the high-voltage battery, SOCa above which the idle stop operation permitted is set, fitted to an initial condition wherein the high-voltage battery has not undergone deterioration. On the other hand, when the internal resistance R is greater than or equal to the predetermined value R1, the threshold value tSOCa is varied to higher value. Further, a target SOC of the high-voltage battery is varied in response to the degree of deterioration of the battery.

  • Patent number: 6452286
    Abstract: When a vehicle is decelerating a controller of a motor-generator (2) computes a target charging current according to a charge state of a high voltage battery by a target charging current computing unit (23), and limits this current by a first limiter (24) having a limiter value. An electrical load current supplied to vehicle-mounted electrical loads is computed by an electrical load current detecting unit (27). A target generation current produced by the motor-generator (2) is computed by adding the target charging current and electrical load current, by a target generation current detecting unit (28, 30). This computed value is limited by a second limiter (31) having a limiter value which varies according to an engine rotation speed, ON/OFF state of an air-conditioner and speed ratio.

  • Patent number: 6406191
    Abstract: The closed end 11b of the Sleeve 11 and the shaft end 12b are made to be point-contacted through the ball 14. By this point contact, while allowing the sleeve 11 and the shaft 12 to rotate, the pressurization in the axial direction between the sleeve and the shaft can be received. Further, by giving this pressurization, the inner ring 13a of the bearing 13 is displaced toward the axial direction (downward in FIG. 1) interposing the ball 13b to absorb the play of the bearing 13. Accordingly, even though merely one bearing 13 is used, the sleeve 11 and the shaft 12 are prevented from being deflected, to obtain the pivot assembly 10 having a necessary rotation precision.

  • Patent number: 6340617
    Abstract: A method of manufacturing a semiconductor device having shallow p-n junctions and silicide regions, capable of meeting both requirements of a high annealing temperature and a low annealing temperature. A lamination of two films made of materials having different etching characteristics is formed on the surface of a silicon substrate, covering an insulated gate electrode structure. The upper film is anisotropically etched to form side wall spacers. Impurity ions are implanted into a surface layer of the silicon substrate and sufficiently activated to a first level. The lower film is removed by using as a mask the side wall spacers, and a metal film capable of being silicided is deposited to perform a first silicidation reaction. The insulated gate electrode is exposed and impurity ions are implanted shallowly in the surface layer of the silicon substrate.

  • Patent number: 6032639
    Abstract: A diagnostic system for a fuel system of an internal combustion engine such as direct-injection gasoline engine monitors a pressure deviation of a actual fuel pressure sensed by a fuel pressure sensor from a desired fuel pressure in a feedback fuel pressure control, and thereby detects abnormality in the fuel system. When the pressure deviation continues to be outside a normal range, a diagnostic controller commands engine operation in a homogeneous stoichiometric combustion mode, and monitors a feedback correction quantity in a feedback stoichiometric air fuel control during the engine operation in the homogeneous stoichiometric combustion mode. The controller attributes the abnormality to the fuel pressure sensor if the feedback correction quantity of the air fuel ratio is fixed to an upper limit or a lower limit.
