Abstract: Solar heat collecting apparatus, wherein plural reflecting mirrors are disposed in north-south direction; the plural reflecting mirrors are provided with heliostat mechanism; the heliostat mechanism includes an east-west angle adjustment unit, having a rotating ring, to adjust the angle of reflecting surface of the plural reflecting mirrors in the east-west direction, and a north-south angle adjustment unit, having actuators, to adjust angle of reflecting surface of the plural reflecting mirrors in the north-south direction; the angle of reflecting surface of the plural reflecting mirrors on each reflection line is simultaneously adjusted via the frame by rotation of the rotating ring; the angle of reflecting surface of each reflecting mirror is individually adjusted by a back-and-forth motion of an arm of the corresponding actuator; and, each reception line is provided with a receiver, and the receiver collects heat from the reflected light of the sunlight reflected by the plural reflecting mirrors.

Abstract: A heliostat apparatus includes one mirror frame supporting a reflecting mirror; a pair of north-south rotational shafts to rotate the mirror frame in the north-south direction; an east-west rotational shaft to rotate the mirror frame in the east-west direction with the north-south direction as the rotational axis direction; a pair of arms projecting from the east-west rotational shaft to the east and west; an east-west rotational shaft support allowing east-west rotational shaft axial rotation; and the north-south rotational shafts positioned to face each other on the ends of the arms. The mirror frame rotation, etc. as an integrated unit in the east-west direction with the east-west rotational shaft as the rotational axis adjusts a reflecting mirror reflecting surface east-west angle. With the north-south rotational shaft as the rotational axis, the mirror frame rotation in the north-south direction adjusts the north-south angle of at least one reflecting mirror reflecting surface.

Abstract: An automobile temperature control system has a motor chamber on which a secondary cell or a fuel cell is mounted for driving wheels by a motor and a cabin and controlling a temperature of portions of the automobile. The temperature control system includes at least one catalytic heater and a fuel tank. The catalyst heater generates heat when an oxidizing gas and fuel from the fuel tank are supplied to the catalyst. At least part of the gas supplied to the catalyst and heated by the generated heat is subjected to circulative supply to the catalyst. The temperature of the portion of the automobile is controlled by using heat generated by the catalytic heater. As a result, a system is provided that efficiently controls the temperature of a portion of the automobile so that performance deterioration is prevented and comfortable running is realized even in a cold region.

Abstract: An air conditioning system for conditioning air in a passenger compartment of a motor vehicle includes a secondary cell or a fuel cell for driving wheels with a motor. The air conditioning system further includes a catalyst heater, an air conditioning duct, and an air conditioning fan. The catalyst heater generates heat by supplying a fuel and an oxidizing gas to the catalyst. The air conditioning duct is connected with an intake port and a blowing port. The air conditioning fan is provided in the air conditioning duct so that the air in the passenger compartment can circulate. The air in the air conditioning duct is conditioned by utilization of the heat generated with the catalyst heater so that the air in the passenger compartment is conditioned.
