  • Patent number: 10352384
    Abstract: A disc brake device for a vehicle, the disc brake device is equipped with: a piston slidably fitted into a cylinder hole provided in one arm section of a brake caliper, and capable of pressing against one friction pad; a shim plate mounted on a back plate of the one friction pad and interposed between the back plate and the piston; and a pressing device that applies pressing force to the piston while causing rotational force to act on the piston. Multiple protrusions protruding toward the piston are provided, with intervals between the protrusions, on the back plate of the friction pad facing the piston with the shim plate therebetween, and multiple engaging holes, into which the multiple protrusions are fitted, are provided on the shim plate so as to prevent the shim plate from rotating together with the piston due to the rotational force.

  • Publication number: 20160348272
    Abstract: In a method for manufacturing a group 13 nitride crystal, a seed crystal made of a group 13 nitride crystal is arranged in a mixed melt containing an alkali metal and a group 13 element, and nitrogen is supplied to the mixed melt to grow the group 13 nitride crystal on a principal plane of the seed crystal. The seed crystal is manufactured by vapor phase epitaxy. At least a part of contact members coming into contact with the mixed melt in a reaction vessel accommodating the mixed melt is made of Al2O3. An interface layer having a photoluminescence emission peak whose wavelength is longer than the wavelength of a photoluminescence emission peak of the grown group 13 nitride crystal is formed between the seed crystal and the grown group nitride crystal.

  • Patent number: 9505398
    Abstract: A vehicle control apparatus computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes. The vehicle control apparatus includes a control section that calculates an engine efficiency of an engine and an MG-INV efficiency which is a combined efficiency of a motor generator and an inverter. The engine efficiency is calculated based on an engine power and an ideal fuel consumption line. The MG-INV efficiency is calculated based on an MG power. As such, based on the engine efficiency and the MG-INV efficiency, the control section computes the per-unit-electric-power fuel consumption decrease or the per-unit-electric-power fuel consumption increase.

  • Patent number: 9499159
    Abstract: A vehicle control apparatus uses a travel mode selection unit to select between an EV travel mode, an engine travel mode, and an engine generation mode depending on comparisons between an engine generated power cost, an EV effect, and a surplus electric energy. In such manner, according to a travel condition of a vehicle, an appropriate travel mode is selected for an improvement of fuel consumption efficiency. The vehicle control apparatus also computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes based on an engine efficiency and an MG-INV efficiency. In such manner, fuel consumption increase/decrease for every travel mode may be computed.
