Abstract: In a refrigeration unit 4 disposed in a machine room 3 of a refrigerator or the like, an expansion valve cover 11 and a pressure switch mounting plate 12 are disposed in the side of a refrigerant compressor 8 placed behind a fan motor 6, and at positions which are in a lateral side of the refrigerant compressor 8 and separated therefrom by a gap, and which are deviated from the direction along which cooling air from the fan motor 6 is ejected. The cover and the plate are disposed so as to elongate in substantially parallel with a side face of the refrigerant compressor 8. A cooling air passage 20 is formed in each of both the sides of the refrigerant compressor 8.

Abstract: Disclosed is a piston-stroke adjusting mechanism of a hydraulic tool comprising an oil tank, a ram for causing the forced feed of an oil, and a piston permitted to slide by the pressure of a working fluid. The piston is formed with a through bore into which an adjust pin is slidably inserted in a manner that an end thereof is directed toward the bottom of a cylinder. The piston is rotatably mounted with an adapter at its head section. The adapter has a small-diameter portion at one side thereof which is located in the through bore to be connected to the adjust pin.

Abstract: A picture of a person is photographed by an electronic camera such as TV camera, and output image data signal thereof is differential-operated, so that a line pattern picture signal is produced; then by making a light image of the line pattern picture on a TV set, a photosensitive resin layer is exposed, and by developing it a stamp of the line pattern picture is produced.

Abstract: A laminated core product producing apparatus wherein a projection is formed on part of a strip of core sheet material and core sheets are punched out of the strip and assembled in a linearly moving stack into the laminated core product by making use of the mutual fitting and crimping of the projections on the core sheets. The dimension of the laminated core product in the direction of the thickness of the core sheets is determined by controlling the intermittent punching out of the projections. A marking mechanism selectively marks a portion of the lateral side edge of a core sheet to be punched out, and at least one proximity sensor provided adjacent the stacked core sheets being assembled into the core product produces a signal corresponding to the distance of a marked core sheet from the head of the stack during movement of the marked core sheet along the stack.

Abstract: A component mounting apparatus includes a pushing member for inserting a pair of terminal wires of an electric component into a circuit board and a clinching mechanism operatively provided below the circuit board for bending the terminal wires, extending outwardly from the circuit board, sideways in a direction towards each other for fixedly mounting the electric component on the circuit board. The clinching mechanism includes a pair of arms which come into contact with the terminal wires for bending the same. Each of the arms is provided with a pair of stress detecting elements which detects the stress set up in the arm upon contact between the arm and the terminal wire for detecting whether or not the electric component is properly mounted on the circuit board.
