Abstract: Mobile power generator apparatus includes: upper and lower pivoting links vertically pivotably connected at their one end portions to a frame; and a handle mounted to the frame for pulling the generator apparatus and connected at its proximal end portion to other end portions of the links. The handle is expandable, in a direction where a grip moves away from the links, in interlocked relation to upward pivotal movement of the links responsive to a pulling force, and is collapsable, in a direction where the grip moves toward the links, in interlocked relation to downward pivotal movement of the links responsive to a pushing force.

Abstract: Mobile power generator apparatus includes: left and right wheels attached to a frame having a power generator mounted therein; three guide rollers provided for each of the wheels for rotatably supporting the rim of the wheel at three positions of the rim; and mounting sections for respectively mounting the three guide rollers on a side wall of the frame, so that each of the wheels is rotatably supported by the three guide rollers on one of the side walls of the frame.

Abstract: An engine operated generator is provided with an engine, a generator driven by the engine, and a power control unit for controlling the power generated by the generator. A fuel gas stored in fuel bottles set in a case for the engine operated generator, is supplied to the engine though a fuel pressure regulator. The fuel bottles and the fuel pressure regulator are disposed adjacent to the power control unit to enable heat exchange with the power control unit provided with an inverter. Thus, heat is mutually utilized between the power control unit and at least one of the fuel bottles as fuel receptacles and the fuel pressure regulator.

Abstract: A portable engine generator has a box-shaped case defining an internal space for holding an engine and an electric generator to be driven by the engine. The case is provided with carrying handles. The portable engine generator is provided with a cooling air passage through which fresh air as cooling air flows into the internal space while the engine is in operation. An inward depressed part is formed in a front cover of the case on the side of the internal space with respect to the carrying handles. The carrying handles and the inward depressed part define the cooling air passage. The cooling air passage serves as a hand space into which human hand is inserted to grip the carrying handles.

Abstract: A circulating path 12 is provided for circulating a heat transfer medium across the cooling section 6A and an exhaust heat exchanger 9. The circulating path 12 is communicated to an output heat exchanger which is mounted on a hot water storage. The heat transfer medium is circulated by a pump 10 from the exhaust heat exchanger 9 to the oil heat exchanger 5 and the cooling section 6A. The heat transfer medium to be introduced into the exhaust heat exchanger 9 is so controlled in the flow rate that a temperature of the water vapor in the exhaust gas is declined to a temperature lower than the dew point. The heat transfer medium when having received heat directly from the exhaust gas and heat generated by condensation of the exhaust heat is conveyed to the cooling section 6A where its temperature soars up further.

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.
