Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent the warpage of a substrate in supporting a board, by equipping the board processor with a substrate support arm which has a sub strate support for supporting the board from rear side, inside the periphery of the substrate. SOLUTION: Though several times of heat treatment is performed for a large-sized board in a vertical diffusion furnace to manufacture an active matrix substrate for a liquid crystal display, in this vertical diffusion furnace, a board support arm 260 is made in a boat made of silicon carbide for inserting a large- sized board horizontally into a quartz reaction chamber. This way, when supporting the rear of the large-sized board by a board supporting arm 260, the two board supports of a board supporter are not abutted against only the outermost periphery of the large-sized board, but the board support 261 in the board support arm 260 is abutted against the position inside the rear periphery of the large-sized board. Accordingly, even if heat treatment is performed, a warp does not occur in the large-sized board.

Filed: 1992-02-14
Abstract: PURPOSE:To prevent an image carrier from being damaged by a spring pulling both supporting bodies so that pressing force may be reduced when a spacer is pressing on the image carrier where the image carrier and a developing device are supported by each supporting body through each shaft. CONSTITUTION:One end of a tension spring 37 is locked on a pin 38 planted on a container 8, and the other end thereof is locked on a pin 39 planted on a frame 32, then moment D in a reverse direction to moment C in a clockwise direction by gravity W with respect to a shaft 33 is formed by the elastic force of the spring 37. At a position where the spacer is allowed to press-contact with a photosensitive body, the magnitude of the moment D is smaller than that of the moment C, and the spacer is allowed to surely press-contact with the photosensitive body by the gravity moment C. The moment by the spring 37 is in the reverse direction to the moment by the force F, so the moment making the spacer press-contact with the photosensitive body is also reduced.
