  • Patent number: 7311637
    Abstract: In an automatic transmission control system, an operating amount of a throttle due to a driver's depression of an accelerator pedal is detected, and the rotating number of an engine suitable for the detected throttle operating amount is detected. The automatic transmission control system includes a shift map defined by the throttle operating amount and the engine rotating number. The actuation of upshift or downshift of a transmission is automatically controlled based on the shift map. The driver can be informed of a point where a shift map is switched by a depression operation of the accelerator pedal so that generation of unnecessary downshift and delay of upshift are prevented to allow a vehicle to be efficiently driven.

  • Patent number: 7261673
    Abstract: In an automatic transmission having a clutch and a gear type transmission, a control unit for inputting detected signals from the operating condition detecting device, and outputting control signals to the gear changing device and the clutch drive device based on the detected signals. The control unit determines whether a stop intention condition of a driver is satisfied or not, and performs first gear change control for, if the stop intention condition is determined to be satisfied, disengaging the friction clutch and changing the gear type transmission to a neutral position, and second gear change control for, when an accelerator opening becomes greater than or equal to a predetermined value, after the friction clutch is disengaged and the gear type transmission is changed to the neutral position by the first gear change by the first gear change control, changing the gear type transmission to a gear according to a vehicle speed, and engaging the friction clutch.

  • Patent number: 6623296
    Abstract: A plug socket includes an intermediate plug having an intermediate slit into which a terminal blade of an insertion plug is inserted and an intermediate terminal blade, a case part containing a main terminal blade-receiving element into which the intermediate terminal blade is inserted, and a mounting element for securing the case part onto a wall surface. The mounting element includes a recessed portion as a housing space for the intermediate plug, and a main slit is provided at the bottom face of the recessed portion for inserting the intermediate terminal blade. Accordingly, the intermediate plug arranged within the recessed portion is interposed to connect the insertion plug with the main terminal blade-receiving element. Therefore, such a socket can be provided that prevents breakage of the terminal blade-receiving element of the socket due to frequent insertion/removal of the insertion plug and allows for easy repair even if broken.

  • Patent number: 5960698
    Abstract: A small diameter cylinder 1a and a large diameter cylinder 1b connected to it are formed in a housing, and a stepped piston 8 comprising a large diameter part 8b and small diameter part 8a is inserted in these cylinders. A first pressure chamber 14a is formed on the small diameter cylinder side and a third pressure chamber 14c is formed on the large diameter cylinder side by the stepped piston 8, and an annular second pressure chamber 14b is formed on the outer circumference of the small diameter part of the stepped piston 8. An intermediate cylinder 10 is formed inside the stepped piston 8, and houses a piston 5 free to slide inside it which forms a fourth pressure chamber 14d. The fourth pressure chamber 14d is permanently connected to the third pressure chamber 14c. A rod 4 connected to the piston 5 passes through the stepped piston 8 in an axial direction. An end stopper 11 limiting the magnum stroke L1 of the piston 5 is provided, and sets the maximum stroke L2 of the stepped piston 8.

  • Patent number: 5852952
    Abstract: A transmission operating apparatus includes a booster for increasing the transmission operating force, and a buffer device for suppressing rapid shift-changes caused by a change in the load due to the damper action of a hydraulic damper mechanism. A by-pass is incorporated into the buffer to permit working fluid to flow into damper chamber by-passing an orifice when necessary. A sealing member having a sealing portion is interposed in the by-pass to seal the by-pass under normal conditions but is resiliently deformed releasing the seal when the working fluid flows into the damper chamber.
