Abstract: An image forming apparatus includes an apparatus body including a drive source, a rotary member, and a first coupling movable in an axial direction with respect to the rotary member, and a unit attachable to and detachable from the apparatus body, the unit including a second coupling configured to receive the driving force by engaging with the first coupling. The rotary member includes an abutting portion. The first coupling includes an abutted portion configured to be abutted with the abutting portion, and is configured to rotate in the first rotation direction together with the rotary member in a case where the abutting portion presses the abutted portion. The apparatus body further includes a first urging member configured to urge the first coupling in a second rotation direction opposite to the first rotation direction.

Abstract: A vehicle frame structure includes a pair of side members located on both right and left sides of a vehicle, each of the pair of side members extending both forward and rearward of a cabin along a respective side of the cabin. As each of the pair of side members extends in a longitudinal direction at a substantially uniform height, a load applied to one end can be transferred toward the other end.

Abstract: A projection type video display apparatus having a projection lens opening (3) formed in the front end (1a) of the apparatus and a lend adjustment opening (5) formed in one end adjacent the front end, both openings protected against dust and external mechanical shocks. The projection type video display apparatus is adapted to project an image that is generated by modulating light emitted from a light source based on video signals, through a projection lens unit (2) exposed in the projection lens opening (3). The apparatus comprises lens adjustment members (e.g. adjustment dial 4) for zooming and/or focusing the projection lens unit (2), and a cover mechanism (slide cover 7) for opening and closing the projection lens opening (3) and lend adjustment opening (5).

Abstract: A hermetic seal for sealing a mouth of a wide-mouthed bottle having a body portion thinly formed by stretch blow molding, and a wide-mouthed bottle a mouth of which is sealed by the hermetic seal. A synthetic resin laminated sheet comprising an aluminum sheet or an aluminum foil as a base is punched into the same shape as a mouth of the wide-mouthed bottle to form the hermetic seal. The sheet is formed into a flat peripheral portion and a bellows inside the flat portion to have alternate multiple mountain and valley portions by press molding concurrently with the punching.

Abstract: The present invention relates to a method of cleaning a surface of a substrate employed prior to film formation by using the CVD method which uses a reaction gas containing an ozone containing gas which contains ozone (O.sub.3) in oxygen (O.sub.2) and tetraethylorthosilicate (TEOS). The substrate surface cleaning method comprises the steps of oxidizing particles 13 by contacting a pre-process gas containing ozone 15 to a surface 12 of a substrate 11 on which the particles 13 are present, and removing the particles 13 by heating the substrate 11 to exceed a decomposition point of oxide 13a of the particles 13.

Abstract: An apparatus, for forming a film according to an automated continuous CVD (Chemical Vapor Deposition) method includes a wafer holder having a plurality of separate, detachable susceptors, a rotary shaft for rotating the wafer holder to rotate wafer mounting surfaces of the susceptors in one plane, a gas distributor spaced from the wafer holder and facing the moving surface of the wafer mounting surface to discharge a reaction gas onto the wafer mounting surfaces, and a heating instrument spaced from the wafer holder and facing the moving surface of the opposite side of the wafer mounting surfaces, in order to keep the wafer at a stable temperature during forming a film and to allow maintenance and repair to be easily and efficiently performed.

Abstract: An apparatus for forming a film by the CVD method allows reaction products to be easily removed from a gas discharge surface without decreasing the uptime/downtime ratio, and includes a gas distributor having a gas discharge surface for discharge of a reaction gas for forming a film on a substrate. A wafer holder has a wafer mounting surface facing the gas discharge surface. A cleaner has a suction head and a brush formed at the entrance of the suction head. A rotary shaft supports the cleaner for movement between the gas discharge surface and a stand-by position and brings the brush of the cleaner onto the gas discharge surface. A vertical positioner moves the wafer holder or gas distributor upward or downward, whereby the wafer holder approaches the gas discharge surface for forming a film and is spaced from the gas discharge surface when cleaning the gas discharge surface by movement of the cleaner on the gas discharge surface.
