A clothes drying apparatus includes a heat pump mechanism (25), an air path (13) for guiding drying air into a drying drum (11) accommodating therein clothes (27), a blower (15) for supplying drying air to the air path (13), and a controller for controlling a driving of a compressor (22), wherein the controller operates the blower (15) and the compressor (22) during a drying operation; stops the compressor (22) in case the drying operation is suspended; and operates, in case the drying operation is resumed, the compressor (22) after a certain time period has elapsed since the compressor (22) had stopped. In case employing the heat pump mechanism (25) having the compressor (22) as a heat source, it is possible to reduce a load on the compressor (22) and allow temperature of warm air to rapidly return by using the heat pump mechanism (25). <IMAGE>

An industrial robot 10 comprises an arm 2 which includes a proximal portion rotatably supported on a horizontal rotation shaft of a frame 1 in a cantilever state, a cylindrical case portion formed from the proximal portion side to a distal end of the arm to have an opening portion on the proximal portion side, and an arm distal end portion. The industrial robot also comprises a balancer device which includes a rod 3b , and a cylinder 3a in which the rod 3b is reciprocated. An engagement portion at a distal end of the rod, and a rear end 5 of the cylinder are rotatably supported between a pair of first support portions c of the frame, and between a pair of second support portions b inside the cylindrical case portion, respectively, so that the cylindrical case portion and the balancer device do not interfere with each other in an extent of rotation of the arm.

A thermal fuse includes an insulating case having a bottom and having an opening provided therein, a fusible alloy provided in the insulating case, a lead conductor having one end connected to the fusible alloy and other end led out from the insulating case through the opening of the insulating case, a flux provided on the fusible alloy, and a sealer for sealing the opening of the insulating case. The volume of a space between the fusible alloy in the insulating case and the sealer is larger than the volume of the flux. Sealing of the fuse is prevented from deteriorating, and the insulating film is prevented from damage even when the thermal fuse is used for breaking a large current at a high voltage.

To discharge high pressure liquid compressed when liquid refrigerant is sucked into a compression chamber to an outside without making the same enter into a back pressure area of a turning scroll or the like. A communication flow path 21 establishing communication between the compression chamber and the back pressure area of the turning scroll 20 is provided in a base plate and a lap of the turning scroll, and a relief mechanism 1 releasing predetermined pressure fluid in the compression chamber connecting to the communication flow path provided in the lap of the turning scroll 20 is provided in a fixed scroll 10. Consequently, entrance of liquid refrigerant into the back pressure area 31 is reduced while easily discharging liquid refrigerant at a time of pressure rise due to suction of liquid refrigerant to the compression chamber.; Also, if oil containing much refrigerant foams in the back pressure area 31 or the like, oil is discharged to the compression camber through the communication flow path 21 of the turning scroll 20 and is discharged from the relief mechanism 11 of the fixed scroll 10. Consequently, unexpected pressure rise in the back pressure area and the compression camber is reduced.

A shoe midsole is configured from a bottom plate (1), a cover (2), a plurality of blades (3), and a liquid (4). The blades (3) are formed so as to rise on a first region (11) provided in the bottom plate (1). The blades (3) are made from a plurality of flat blade elements (32, 33) mutually separated by slits (31) and tilt toward either the toe side or the heel side. The flat blade elements (32, 33) are disposed so as to spread open toward the toe side or the heel side. A sealed space (5) is formed by mutually joining the bottom plate (1) and the cover (2), and the liquid (4) is sealed in the sealed space.
