    摘要: A medium area (S) filled with liquid xenon (2) is formed between an external cylindrical body (1a) and internal cylindrical body (1b), and a pair of anode pads (11, 12) are disposed in two-dimensional form in opposite end portions of the medium area (S) in the intersection direction with respect to the gamma-ray incident direction. An intermediate electrode (10) is disposed between a pair of anode pads (11, 12), and a plurality of photomultiplier tubes (5) is installed in two-dimensional form in the external cylindrical body (1a). Then, the gamma-ray reaction point within the liquid area (S) is identified from signals output from the anode pads (11, 12) and photomultiplier tubes (5).

    摘要: Disclosed is a centrifugal spark-advance control device for an ignition system of an internal combustion engine, comprising: a base plate which rotates at a speed corresponding to the rotational speed of the engine; a timing plate which is rotatably supported on the base plate; a spring for biasing the timing plate in a certain direction; a centrifugal weight which is pivoted to the base plate at a point spaced from the center of gravity of the centrifugal weight and which is provided with a cam surface for rotatably driving the timing plate in an opposite direction against the biasing force of the spring by cooperating with a corresponding cam follower surface provided in the timing plate; a spark generating device coupled to the timing plate for generating ignition sparks in synchronism with the rotational angle of the timing plate; a mass member attached to the timing plate by way of an elastic member. Since the mass member is elastically supported by the timing plate, undesirable vibration of the timing plate is minimized by the action of a dynamic damper provided by the mass member and the accuracy in ignition timing is assured.

    摘要: A cooling control apparatus for an automobile engine having a radiator and two or more electrically operated fans for circulating air through the radiator. Each fan is operated in response to a different predetermined temperature of the cooling water in the radiator so that first one fan is activated under normal operation and the second fan is operated only under heavier loads or high ambient conditions requiring additional cooling. In one embodiment a fan is operated upon activation of the air-conditioning system to cool its condenser regardless of the cooling water temperature.

    摘要: A system for reducing the temperature of exhaust gas in an incinerator or boiler equipment having an exceedingly small size and avoiding any difficulties caused by damage to the wall surface of a gas cooling chamber due to adherence of sprayed water droplets and deposition of dust. More specifically, pressurized thermal water with a temperature higher than a boiling point of water under atmospheric pressure is sprayed as temperature reduction water into high temperature exhaust gas Gh in a gas cooling chamber or an exhaust gas duct. The temperature reduction of exhaust gas and the removal of acidic gas in the exhaust gas are simultaneously achieved by spraying pressurized thermal water Wt containing an alkaline solution as temperature reduction water into high temperature exhaust gas Gh in the gas cooling chamber or the exhaust gas duct.
