  • Patent number: 7210950
    Abstract: In a connector for memory card, it is objected to stabilize contact of detection switch for detecting insertion of a memory card, and to prevent breakage of the memory card due to bounce-out when it is taken out. The detection switch is held on a contact block with contacts which are to be contacted with terminals of the memory card, and comprised of a fixed contact plate and a movable spring piece. A groove having substantially V-shape is formed on a contacting portion of the movable spring piece so as to contact with the fixed contact plate at two points. Furthermore, elastic protrusions that can fit to recessed portions for locking formed on the memory card just before the slider holding the memory card reaches to an initial position is formed on a top plate of the housing, so that the bounce-out of the memory card is prevented.

  • Publication number: 20070050107
    Abstract: A wheel-speed-sensor-anomaly detection apparatus detects anomaly of wheel speed sensors of a vehicle. When a difference between the minimum wheel speed among detected wheel speeds and the smallest value among the remaining wheel speeds is greater than a predetermined threshold value, in principle, a wheel speed sensor of the wheel corresponding to the minimum wheel speed is determined to be anomalous. Meanwhile, when a wheel having a lowered tire air pressure (air-pressure-lowered wheel) is present and a road surface on which the vehicle is currently traveling is a low-? road surface, the operation of detecting anomaly of the wheel speed sensors is prohibited. This operation reliably prevents erroneous detection of anomaly of the wheel speed sensor of the air-pressure-lowered wheel, which erroneous detection would otherwise occur due to the locking tendency of the air-pressure-lowered wheel occurring because of decreased tire air pressure, in particular, on a low-? road surface.

  • Publication number: 20060267401
    Abstract: This apparatus is applied to a vehicle brake apparatus provided with a hydraulic booster operated by utilizing an accumulator hydraulic pressure that is adjusted to a predetermined high pressure (not less than a lower limit value) by a drive control of a hydraulic pump. This apparatus executes an automatic pressurization control by controlling plural solenoid valves with the use of the accumulator hydraulic pressure. The increasing slope of the brake hydraulic pressure during the automatic pressurization control is determined on the basis of the vehicle motion state. The increasing slope is restricted to be not more than a predetermined restriction value, in case where the accumulator hydraulic pressure at the time of starting the automatic pressurization control is less than “a reference hydraulic pressure that is greater than a minimum value of the accumulator hydraulic pressure necessary for assisting the brake operation by the hydraulic booster and smaller than the lower limit value”.
