Abstract: <P>PROBLEM TO BE SOLVED: To provide an inexpensive and strong heat exchanger by forming a constant falling liquid film, and also to provide a compact and high performance absorption refrigerating machine using it.  <P>SOLUTION: In this heat exchanger, heats are exchanged between in-pipe fluid flowing inside a heat exchanger pipe 3 and out-pipe fluid flowing outside the pipe. A plurality of the heat exchanger pipes 3 are arranged in a horizontal direction, and stacked in an upward and downward direction in a manner that they are almost brought into close contact with outer faces of the pipes 3, so as to form a heat exchanger pipe unit 4. A plurality of the units 4 are arranged in a horizontal direction at predetermined intervals, and both ends of the pipe 3 are jointed with a pipe plate 2 or a header for in-pipe fluid. The pipe 3 is shaped into a circle at both ends, and into an ellipse or a general rectangle longer in an upward and downward direction at the middle. Height dimension of the pipe in the upward and downward direction at the middle is larger than outside diameter of both ends. The outer surface of the pipe 3 had better to be applied with a hydrophilic treatment for improving wettability. In this absorption refrigerating machine, the heat exchanger is used for at least one facility of an evaporator, an absorber, a regenerator and condenser constituting the absorption refrigerating machine.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a viscous coupling, in which fuel consumption and emitted exhaust gas are suppressed to protect the environment, by reducing torque transmission according to differential rotation at the time of normal running or high-speed running.  <P>SOLUTION: Since a centrifugal governor 67 is moved to a center side by an urging means 65 at the time of low-speed running small in number of revolution of a housing 31, a float 71 is moved to the outside in an operating chamber 35. Therefore, viscous fluid 41 in a positions of an outer plate 45 and an inner plate 47 is deep and a contact area is enlarged, so that the transmission torque is increased. On the other hand, since the centrifugal governor 67 is moved to the outside against the urging means 65 by the centrifugal force when the housing 31 rotates at high speed, the float 71 is moved to the center side in the operating chamber 35. The viscous fluid 41 is shallow and the contact face gets small, so that the transmission torque is decreased.  <P>COPYRIGHT: (C)2003,JPO
