Abstract: Provided are a three-way valve for flow rate control and a temperature control device, which have improved sealing performance against a fluid having a low temperature of about ?85° C. as compared to a case in which a pressure applying portion does not include a communication member having a cylindrical shape with both end portions in a longitudinal direction sealed by sealing means including a coating member, which has a substantially U-shaped cross section and is made of a synthetic resin, and is urged in an opening direction by a spring member made of a metal.

Abstract: Provided is a flow rate control valve capable of suppressing leakage of a fluid when the flow rate control valve completely closes a valve port as compared to a flow rate control valve that does not include a gap reducing portion being provided so as to partially reduce a gap between a valve body and a member opposed to the valve body, and a temperature control device using the flow rate control valve.

Abstract: A valve unit includes a first solenoid valve for a first fluid in a first channel; a first branch channel branched from the first channel on the upstream side of the first supply-side solenoid valve; a first branch-side switching valve for the first fluid in the first branch channel; a second solenoid valve for a second fluid in a second channel; a second branch channel branched from the second channel on the upstream side of the second solenoid valve; a solenoid switching valve for the second fluid in the second branch channel; a reception channel to receive a fluid from a first outlet opening or a second outlet opening to flow through a predetermined area and returns; first and second circulation channels bifurcated from the reception channel; a first circulation-side solenoid valve for the first circulation channel; and a second circulation-side solenoid valve for the second circulation channel.

Abstract: A temperature control system includes: first and second refrigerator units; a first fluid flow apparatus that allows a first fluid to flow therethrough and that is cooled by the first refrigerator unit; a second fluid flow apparatus that allows a second fluid to flow therethrough and that is cooled by the second refrigerator unit; and a valve unit that is configured to allow the first fluid or the second fluid to selectively flow out therefrom. The first refrigerator unit has, in a medium-temperature-side refrigerator, a medium-temperature-side first expansion valve and a medium-temperature-side second expansion valve. A medium-temperature-side second evaporator corresponding to the medium-temperature-side second expansion valve and a low-temperature-side condenser of a low-temperature-side refrigerator constitute a cascade condenser.

Abstract: A heat exchanger provided with: a plate member having a flat bottom part and a refrigerant flow path formed therein; and a plate cover for covering the plate member. The plate cover has a refrigerant inlet communicating with an area on one side of the refrigerant flow path, and a refrigerant outlet communicating with an area on the other side of the refrigerant flow path. The refrigerant flow path is more densely arranged in an area far from a straight line connecting the area that is on the one side and communicates with the refrigerant inlet to the area that is on the other side and communicates with the refrigerant outlet, than in an area close to the straight line connecting the area that is on the one side and communicates with the refrigerant inlet to the area that is on the other side and communicates with the refrigerant outlet.

Abstract: A temperature control apparatus is provided, which is capable of, even when it is necessary to perform control by means of valves in a plurality of channels, promptly controlling a temperature of an area to be temperature-controlled promptly to a desired temperature. Passage and blockage of a heating medium passing through a first supply channel to a mixing channel, a temperature of the heating medium being controlled by a first temperature regulating unit at a predetermined temperature, and passage and blockage of a heating medium passing through a second supply channel to the mixing channel, a temperature of the heating medium being controlled by a second temperature regulating unit, are controlled by a valve unit. The valve unit includes a first spool valve and a second spool valve, which are coupled through a heat insulating layer.

Abstract: A temperature control apparatus is provided, which is capable of, even when it is necessary to perform control by means of valves in a plurality of channels, promptly controlling a temperature of an area to be temperature-controlled promptly to a desired temperature, while avoiding complication and enlargement of the apparatus as a whole. Passage and blockage of a heating medium passing through a first supply channel to a mixing channel, a temperature of the heating medium being controlled by a first temperature regulating unit at a predetermined temperature, and passage and blockage of a heating medium passing through a second supply channel to the mixing channel, a temperature of the heating medium being controlled by a second temperature regulating unit, are controlled by a valve unit.

Abstract: A fishing reel includes a pair of side frames, a spool shaft, which is rotatably supported to the side frames, one end of the spool shaft protrudes sidewards from the adjacent side frame, and a spool carried on the spool shaft between the side frames. A handle shaft extends from the same side frame from which the spool shaft protrudes sidewards so that the lengthwise axis of the handle shaft is in parallel relationship to that of the spool shaft. A handle is operatively connected to the handle shaft for applying rotational force to the spool. A direction maintaining mechanism is provided between the handle shaft and the spool shaft such that the rotational force effected by the handle is transmitted to the spool so as to always rotate the spool in a predetermined direction thereof regardless of rotational direction of the handle. A speed adjusting mechanism is provided between the handle shaft and the spool shaft to adjust a rotational speed of the spool by changing a rotational direction of the handle.
