Abstract: A liquid receiver of a condenser has a liquid receiver main body and a plug removably fitted thereinto. The liquid receiver main body has a refrigerant inflow hole into which refrigerant flows from a condensation section and a refrigerant outflow hole from which refrigerant flows into a supercooling section. The liquid receiver has a first space formed above the upper end of the plug and communicating with the refrigerant inflow hole and a second space formed below the upper end of the plug and communicating with the refrigerant outflow hole. The plug has a flow passage which is open to the first space and the second space at opposite ends. The first-space-side opening of the flow passage is located below the refrigerant inflow hole. The flow passage has a throttle portion whose cross-sectional area is smaller than a hole area of the refrigerant inflow hole.

Abstract: In manufacture of a heat exchanger, heat exchange tubes, fins, and header section bodies are arrange in an assembled condition. Projection pieces provided on caps of header sections are fitted into corresponding slits formed in side plates, thereby engaging end portions of the side plates with the caps. In this condition, the caps are arranged in such a manner as to bridge end portions of the header section bodies, and the side plates are arranged on the outer sides of the leftmost and rightmost fins. The heat exchange tubes and the fins, the heat exchange tubes and the header section bodies, the header section bodies and the caps, the side plates and the caps, and the side plates and the fins are respectively brazed together simultaneously. This method enables the side plates to be accurately arranged at respectively predetermined positions.

Abstract: A second fin 27 is disposed outside a refrigerant passing body 2 positioned at one side end of a heat exchange core 4 where a refrigerant inlet 14 and a refrigerant outlet 15 are provided. A side plate 26 is disposed externally of the second fin 27. The second fin 27 and the side plate 26 have respective upper ends so positioned as to permit an upper portion outer surface of the refrigerant passing body 2 to be exposed. A refrigerant inflow member 16 and a refrigerant outflow member 17 are arranged on the refrigerant passing body 2 at an external portion thereof above the second fin 27 and the side plate 26, and the inflow member 16 is connected to the inlet 14, and the outflow member 17 is connected to the outlet 15. The inflow member 16 and the outflow member 17 have respective outer side faces positioned within an upward extension of the plane of outer side face of the side plate 26 or inwardly of the extension.

Abstract: A heat exchanger used as an evaporator includes a refrigerant inlet header section and a refrigerant outlet header section. The refrigerant inlet and outlet header sections each include a header section body having opened opposite ends and two caps closing opposite end openings of the header section body. The header section body of the refrigerant inlet header section and the header section body of the refrigerant outlet header section are integral with each other. The caps are fitted into the corresponding opposite end openings of the header section bodies. Projections formed at peripheral portions of the caps are fitted into corresponding mating holes formed in tubular walls of the header section bodies. In this condition, the caps are joined to the header section bodies. This heat exchanger allows relatively easy practice of the work of preventing detachment of caps in manufacture thereof.

Abstract: In the present invention, a header tank 10 includes a header tank main body 11 and a cover plate 20. The header tank main body 11 is provided with a refrigerant inlet passage 12a and a refrigerant outlet passage 12b arranged in parallel, connecting apertures 14a and 14b formed on a tube connecting side 13 and communicating with the passages 12a and 12b, and a communicating aperture communicating with the passages 12a and 12b. The cover plate 20 has insertion apertures 24a and 24b corresponding to the connecting apertures 14a and 14b. The tubes 1a and 1b, the cover plate 20 and the header tank main body 11 are integrally joined in a state in which each end of the tube 1a and 1b is inserted into the insertion aperture 24a and 24b of the cover plate 20 disposed on the tube connecting side 13a of the header tank main body 11 and connected to the connecting apertures 14a and 14b of the header tank main body 11.

Abstract: The present invention provides an apparatus for holding a compact disk, composed of a cylindrical body around which the central hole of the compact disk is fit and disk-receiving member, forming a plurality of tongue-shaped members extending between cut openings from the cylindrical body to the disk-receiving member, each with a nail-shaped member at the front end, wherein the nail-shaped members at the end of the tongue-shaped members rise to lift the compact disk when the cylindrical body is pushed downward.

Abstract: An interactive plant monitoring system in which a plurality of interactive functions for monitoring a plant are displayed on a CRT display in a predetermined order, and an input to the plurality of interactive functions is discriminated on the basis of an input signal from an interactive input device realizing an interactive function operation together with the CRT display. The interactive plant monitoring system includes a plant condition discriminating unit for discriminating the plant condition on the basis of the process data output from the plant; a memory for storing the information regarding an interactive function display order which is previously determined for each plant condition; and an interactive function order controller for picking up the interactive function display order information from the memory in accordance with the discrimination result by the plant condition discriminating unit and displaying the information on a monitoring screen.
