摘要： It is an object of the invention to provide an inexpensive double-pipe heat exchanger having high performance and comprising an inner pipe and an outer pipe which constitute a double pipe without adding a heat-transfer facilitating material such as an inner fin. In the double-pipe heat exchanger having the inner pipe and the outer pipe, the outer pipe is dented from its outside toward its inside, thereby forming a plurality of projections which are dented toward the inner pipe. Examples of shapes of the projection are substantially conical shape, substantially truncated shape, substantially spherical surface shape, substantially cylindrical shape, substantially elliptic cylindrical shape and the like. The projections are disposed helically or in a staggered configuration such as to surround the inner pipe. With this structure, only by subjecting the outer pipe to simple working such as press working, it is possible to increase the turbulent flow of fluid flowing between the inner pipe and the outer pipe, and to facilitate heat transfer from fluid flowing in the inner pipe to fluid flowing between the inner pipe and the outer pipe.

摘要： An air conditioner includes a refrigerant charge port provided in an outdoor liquid-side connection valve or an outdoor gas-side connection valve, a liquid-side valve provided between the outdoor liquid-side connection valve and an expansion valve, and a gas-side valve between the indoor gas-side connection valve and a compressor. When an outdoor unit and indoor unit are separated, the liquid-side and gas-side valves are closed, and a refrigerant is charged into an outdoor connection pipe that is closed by the liquid-side valve and the gas-side valve. A control unit is adapted to close the refrigerant charge port, and then open the liquid-side valve and the gas-side valve when a pressure detector detects a predetermined degree of vacuum.

摘要： Qualitative relations between changes in a charge voltage, a developer bias voltage and an exposure light intensity control voltage and change in an image density are investigated in advance, and a density error is derived by a difference between the density of the image of a reference mark and a target density. Respective variations of the charge voltage, developer bias voltage and exposure light intensity control voltage are derived on the basis of the qualitative relations and the density error, and thereby the charge voltage, developer bias voltage and exposure light intensity voltage are changed so as to decrease the density error.
