Abstract: An autonomous flying device achieving a large payload and a long continuous flight time and also accurately adjust position and orientation while flying. The device includes: a main rotor and the like that provide main thrust; a sub rotor and the like that controls the orientation; an engine that generates energy for rotating the main rotor and the like and the sub rotor and the like; and an arithmetic control device that controls rotation of the sub rotor and the like. Also, the main rotor and the like are rotated by being drivingly connected to the engine, whereas the sub rotor and the like are rotated by motors driven by electric power generated from generator and the like operated by the engine. Further, when orientation control to tilt the fuselage is performed, the arithmetic control device increases the output distribution ratio of the sub rotor to above the output distribution ratio of the sub rotor when hovering is performed.

Abstract: A boiler-equipped absorption heat pump unit in which a regenerator, a boiler, and other high-temperature devices are separated from an evaporator, an absorber, and other low-temperature devices are separated by an insulated dividing wall. The dividing wall reduces heat loss by impeding the transfer of heat from the high-temperature devices to the low-temperature devices.

Abstract: A coupling structure for an absorption refrigeration circuit includes a gasket held between two coupling members. The gasket has a protruding part that elastically deforms when clamped between adjoining faces of the two coupling members.

Abstract: A boiler-equipped absorption heat pump unit (10) having reduced heat loss is disclosed. A regenerator (23), a boiler (14), and other high-temperature devices, as well as an evaporator (11), an absorber (12), and other low-temperature devices are separated from each other by a dividing wall (62). The dividing wall impedes the transfer of heat from the high-temperature devices to the low-temperature devices, and heat loss is reduced.

Abstract: An inexpensively manufactured coupling structure (21) for an absorption refrigeration circuit includes a gasket (27) held between two coupling members (23, 26). The gasket has a protruding part (32) that elastically de-forms when clamped between adjoining faces (22, 25) of the two coupling members.

Abstract: A solar generator system includes a solar cell for photo-electrically converting sunlight, a multi-focus lens for condensing and converging the sunlight to the solar cell, and a secondary light-condenser which is formed into an inversed truncated conical shape with a portion adjacent to the lens being of a larger diameter, and which is disposed on the solar cell with a light-receiving face being opposed to the lens so as to introduce converged rays from the lens to the solar cell. The secondary light-condenser has a light-receiving surface which is formed into a cornet shape and includes a circular planar portion, and a slant portion which is formed into a tapered shape with the diameter thereof being larger as it goes away from the lens and which has a smaller-diameter end connected to an outer periphery of the planar portion.

Abstract: An absorption type refrigerating apparatus is provided which is capable of not discharging to the outside but, instead, oxidizes hydrogen gas generated therein to water through reaction with metal oxide to inhibit a reduction of the operational efficiency. The hydrogen gas saved in the condenser 9 is brought in direct contact with a metal oxide of the hydrogen gas removing module 93 provided in the condenser 9. This causes the reducing reaction of the metal oxide to transform the hydrogen gas to water. The module 93 of a reduction unit is accommodated in the condenser 9 thus eliminating the need of a conventional sealing structure where the reduction unit is provided outside and connected by a conduit to the condenser 9. The reducing reaction can favorably be promoted by the heat of a refrigerant vapor introduced into the condenser 9 through its inlet 94.

Abstract: An absorption type refrigerating apparatus is provided capable of not discharging to the outside but oxidizing hydrogen gas generated therein to water through reaction with metal oxide to inhibit declination of the operational efficiency. The hydrogen gas saved in the condenser 9 is brought in direct contact with a metal oxide of the hydrogen gas removing module 93 provided in the condenser 9. This causes the reducing reaction of the metal oxide to turn the hydrogen gas to water. The module 93 or a reduction unit is accommodated in the condenser 9 thus eliminating the need of a conventional sealing structure where the reduction unit is provided outside and connected by a conduit to the condenser 9. The reducing reaction can favorably be promoted by the heat of a refrigerant vapor introduced into the condenser 9 through its inlet 94.

Abstract: For minimizing declination of the operational efficiency, hydrogen gas generated in an absorption type refrigerator is eliminated by reduction without exhausting to the outside. The hydrogen gas H2 remains close to the level surface 93 of a refrigerant in a condenser 9 is transferred together with a refrigerant vapor via an extraction pipe 92 to a condenser tank 91. The condenser tank 91 is equipped with a heated metal oxide which is allowed to come into direct contact with the hydrogen gas for carrying out its reduction. Accordingly, the hydrogen gas is eliminated and a trace of water is generated. The water is then returned back via the extraction pipe 92 to the condenser 9. As a result, the elimination of the hydrogen gas is successfully carried out while the water generated stays in the system, whereby the content of water in the refrigerant can be maintained to a desired level.

Abstract: The purity of a refrigerant liquid can be maintained to an appropriate level without being varied corresponding to a change in the atmospheric condition and the loading state. A portion of the refrigerant liquid in an evaporator is conveyed from the evaporator to the upper end of a rectifier where it is used as a vapor/liquid contact fluid. A temperature sensor T6 is provided at the upper end of the rectifier for detecting the temperature at the top of the rectifier or the temperature of the refrigerant vapor. The temperature and the purity of the refrigerant vapor are closely related to each other. The higher the temperature, the lower the purity is deteriorated. When the temperature T detected by the temperature sensor T6 is higher than a reference temperature level Tref, a flow control valve V5 is actuated to increase the flow of the refrigerant liquid to the rectifier. This recovers the purity of the refrigerant vapor, thus preventing declination of the purity of the refrigerant vapor in the evaporator.

Abstract: An absorption refrigerating/heating apparatus which performs in any of three modes; refrigerating, thermodynamic heating, and direct flame heating and improves the thermal efficiency during the operation of a direct flame heating mode to decrease the running cost. In the direct flame heating mode, the refrigerant and/or the absorbent is passed to the regenerator to decrease the concentration of the absorbent in the solution in the regenerator. Consequently, the temperature of the solution required for maintaining the vapor pressure in the regenerator at a desired rate can be lowered thus saving the heat needed for heating the solution.
