  • Publication number: 20120121496
    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: 8094290
    Abstract: An illumination optical system with a simple structure reduces the effects of illumination variations caused by a spatial coherency of illumination light, while maintaining a high usage efficiency of illumination light that is emitted in pulses. The illumination optical system illuminates an irradiated plane with pulse-emitted illumination light and includes a spatial light modulator including a plurality of mirror elements each of which spatially modulates the illumination light in accordance with an incident position of the illumination light. A modulation control unit controls the mirror elements, whenever at least one pulse of illumination light is emitted, in a manner such that the optical elements spatially modulate the pulses of illumination light differently from one another and form substantially the same intensity distribution for the pulses of illumination light on a predetermined plane.

  • Patent number: 7871135
    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”.
