  • Patent number: 11828334
    Abstract: A power transmission shaft has a shaft member having, on an outer peripheral surface thereof, a male spline; a cylindrical member having, on an inner peripheral surface thereof, a female spline; and a seal member provided in a pressed state between an outer peripheral seal surface formed on the outer peripheral surface of the shaft member and an inner peripheral seal surface formed on the inner peripheral surface of the cylindrical member. The cylindrical member is spline-engaged with the shaft member by one end side of the shaft member being inserted into the cylindrical member from an other end side of the cylindrical member. Axial direction shock is absorbed by sliding of the splines. The outer peripheral seal surface is positioned at the other end side with respect to the male spline, and the inner peripheral seal surface is positioned at the other side with respect to the female spline.

  • Patent number: 9903012
    Abstract: A film formation method is one for forming an organic layer comprising a fluorine-containing resin on an inorganic layer (3) formed on a substrate and comprising an inorganic substance. In the method, for the formation of the inorganic layer, a reactive sputtering procedure using water vapor as a reactive gas is carried out to form the inorganic layer on the substrate. Subsequently, the organic layer is formed on the inorganic layer. A film formation device enables the implementation of the film formation method.

  • Publication number: 20140216332
    Abstract: Provided is a vacuum treatment device, when a lifting pin inserted to a through hole is moved up, a substrate on a placement table is placed on a lid member which is connected to an upper end of a lifting pin and is separated from a placement surface of the placement table. Additionally, when the lifting pin is moved down, the substrate comes into contact with the placement surface so as to be placed thereon. An annular seal member surrounding a periphery of an opening of the through hole is provided in a portion which faces the lid member in a bottom surface of a depression provided in the placement surface of the placement table. The lid member annularly comes into contact with the seal member when the lifting pin is moved down, and a space inside the through hole and a space outside the through hole are separate by the seal member, thereby preventing gas from flowing into the through hole.

    Abstract: The challenge for the present invention is to provide a film-forming method and for forming a passivation film which can sufficiently inhibit the loss of carriers due to their recombination; and a method for manufacturing a solar cell element with the use of the method or the device. The film-forming device comprises a mounting portion 22 for mounting a film-forming object, a high frequency power source 25, and a shower plate 23 which is provided to face the film-forming object S mounted on the mounting portion 22, which introduces a film-forming gas, and to which the high frequency power source is connected and a high frequency voltage is applied. A low frequency power source 26 for applying a low frequency voltage is connected to the shower plate or the mounting portion mounting a substrate. The film-forming method is performed using the film-forming device, and the film-forming method is carried out in forming a passivation film.
