  • Patent number: 7734388
    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: 20100076659
    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 the 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”.

  • Patent number: 7674114
    Abstract: A thin board-to-board connector with high density in which there is no connection between three-dimensional complex metal springs. The board-to-board connector includes a connector having a bump for electrical connection having an umbrella shape on a board and connected to a circuit board and a connector having an elastic electrically conductive section having a through hole made in a conductive pattern on an elastic insulating board and connected to a circuit board electrically connected to the elastic conductive section. When a bump is inserted into the through hole, the elastic conductive section is electrically connected to the bump, and the side surface of the through hole is pressed against to the bump and elastically deformed and dented. Consequently, the bump is press-fit into the through hole.

  • Publication number: 20090318662
    Abstract: A hydrazine-fixing group such as a ketone group, a formyl group, a chlormethyl group or an amide group, which is capable of releasably fixing hydrazine, is introduced into a side chain of a synthetic resin, and hydrazine is fixed to the hydrazine-fixing group. Since a hydrazine storage resin of the present invention has a hydrazine-releasable group capable of releasing hydrazine, it is able to store hydrazine stably. In addition, hydrazine can be supplied by releasing hydrazine from the hydrazine-releasable group. Consequently, the hydrazine storage resin can be widely used in various industrial fields requiring supply of hydrazine.

  • Patent number: 7622418
    Abstract: To provide a method for industrially efficiently producing an exhaust gas purifying catalyst containing a perovskite-type composite oxide which is stable and has a less reduced specific surface area and is also effectively prevented from decreasing in its catalytic performance even in endurance in high temperature oxidative reducing atmospheres, a pre-crystallization composition containing elementary components constituting a perovskite-type composite oxide containing a noble metal is prepared, is mixed with a powder of theta-alumina and/or alpha-alumina to prepare a mixture, and the mixture is heat treated. Thus, the resulting perovskite-type composite oxide supported by the powder of theta-alumina and/or alpha-alumina can keep its thermostability at a sufficient level thereby to effectively prevent the catalytic performance from decreasing. This method can industrially efficiently produce the exhaust gas purifying catalyst.
