Abstract: PROBLEM TO BE SOLVED: To suppress increase in an installation area for a manufacturing device due to larger diameter of a wafer and to allow transportation of a wafer in vertical attitude, by using a wafer carrier hand comprising a plurality of V-like grooves which support the edge part on the down side of circumference of a wafer in vertical attitude. SOLUTION: A transfer handle 20 comprises one fixing claw 24 which is fixed to a plate-like frame 22 directly below a wafer 10 and comprises a V-like groove of almost the same radius as the wafer 10. Two movable claws 26 are provided which comprises a V-like groove of almost the same radius as the wafer 10 and provided to the frame 22 through a gripping actuator 28 at upper two points of the wafer 10. The three claws of the carrier handle 20 grip the wafer 10 and move horizontally in vertical attitude. Since the wafer 10 is held from above and below using movable claws 26, the wafer 10 is surely gripped. Thus, the transportation of a wafer in vertical attitude, including transfer between robots, is allowed even in vacuum.

Abstract: PURPOSE:To reduce size and weight, to simplify operation, and to increase a response speed by a method wherein a variable pitch propeller device for an outboard motor for a small high speed ship comprises a rack engaged with a pinion and a rack operating means to reciprocate the rack, and through operation of the rack operating means, the pitch angle of a propeller is varied. CONSTITUTION:When a rack 46 is operated by means of a rack operating means and an adjust screw 37 is rotated by means of a pinion 45 engaged with the rack 46, a screw part 37A is joined in a screwed-in state with a fixed nut 42, whereby the adjust screw 37 is reciprocated through rotation. Thereby, a control rod 35 coupled to an adjust screw 37 through a bearing 36 is reciprocated. A link 39 coupled through a pin 38 is pulled and closed and a propeller 40 is rotated around a rotary shaft 41 through an eccentric pin 43 coupled to the link 39. This constitution changes the pitch angle of the propeller 40.

Abstract: PROBLEM TO BE SOLVED: To clean not only the surface of a wafer but also the rear surface thereof simultaneously in same degree without prolonging the cleaning time by arranging tubes each arranged with nozzles for cleaning the rear surface around the wafer including the lower symmetrical position and spraying cleaning fluid slightly upward in the horizontal direction. SOLUTION: Tubes 2 each arranged with nozzles 3 for cleaning the rear surface are arranged around a wafer 10 including the lower symmetrical position and cleaning fluid 4 is sprayed slightly upward in the horizontal direction thus cleaning the surface 10F and the rear surface 10R of the wafer simultaneously. A process hand disposed in a cleaning chamber enables to spray the cleaning fluid over the entire surface and rear surface of the wafer when both sides of the wafer are cleaned. In the cleaning chamber, two tubes 2 are arranged with nozzles 3 at a substantially constant interval allowing passage of the wafer and the process hand in order to spray the cleaning fluid toward the lower part of the wafer passing between the tubes.

Abstract: PURPOSE: To provide a robot having high rigidity and accuracy and capable of having a wide operating range by providing a pair of arms that can be raised and lowered and be rotated around bases as a fulcrum, while providing flexible knuckles in the middles of the arms, and enabling a holding device to move in a straight line by the bending motion of the pair of arms. CONSTITUTION: Upper and lower end plates 2 are rotatably journalled to the upper and lower parts of a C-shaped frame 1 and are connected together by two rotatable front spline shafts 8, 9 and a fixed ball spring shaft. When one spline shaft 8 is rotated by the drive of an arm-turning motor, the other spline shaft 9 is rotated in the direction opposite to the rotation of the spline shaft 8 via an interlocking gear 22, a pair of intermediate interlocking gears 24, 25, and an interlocking gear 23. A pair of arms 14, 15 splined to the spline shafts 8, 9 are therefore rotated in opposite directions and, as the arms 14, 15 are bent at knuckles 45 in their middles, they cause mounting flanges 41 at the arm ends to move back and forth in a straight line.
