Abstract: A processes for adhering a vulcanized rubber to a vulcanized rubber or an unvulcanized rubber. Adhesion of vulcanized rubbers to each other is conducted by using at least one of the vulcanized rubbers before vulcanization thereof according to steps of: (1) laminating a sheet material which can easily be peeled from a surface of a rubber after vulcanization to a rough surface of the rubber before vulcanization, (2) vulcanizing a resultant laminate, (3) removing the sheet material from the vulcanized laminate immediately before adhesion of the vulcanized rubber in the laminate to another vulcanized rubber, and (4) adhering the vulcanized rubbers to each other according to a method of adhesion. The adhering of the vulcanized rubbers to each other is also conducted by using a rubber composition for adhesion inserted between the vulcanized rubbers without procedures using the sheet material.

Abstract: Disclosed is a guide lug composition for a rubber track comprising 5 to 40 parts by weight of a fatty acid amide based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a Ultra High Molecular Weight Polyethylene (UHMW-PE) powder based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a fatty acid amide and 5 to 40 parts by weight of a UHMW-PE power based on 100 parts by weight of a raw rubber material. The guide lug composition serves to reduce abrasion of or damages to a guide lug, to improve the characteristics in preventing the rubber track from slipping off a wheel, which is called “detracking”, to reduce friction loss when the guide lug contacts and collides with the wheel thereby reducing energy losses.

Abstract: The electric bending endoscope device according to the present invention comprises: an endoscope having a bending portion; a bending control mechanism for electrically driving the bending portion of the endoscope; a power source voltage monitoring portion for monitoring the source voltage supplied to this bending control mechanism; and a change-over switch for releasing the bent state of the bending portion, when the above-mentioned bending portion is in a bent state, on the basis of an output signal from the source voltage monitoring portion.

Abstract: There is provided a rubber track used for an undercarriage of a vehicle, and particularly an improvement in a guide lug which protrudes from an inner peripheral surface of the rubber track. In the rubber track in which a plurality of rubber lugs are formed on an outer peripheral surface of an endless rubber elastic body and a plurality of guide lugs are formed on an inner peripheral surface of the elastic body, the guide lugs being used for transmission of driving force or prevention of detracking between the guide lugs, and track rollers, idlers or sprockets, a heat-resisting thermoplastic resin member having low friction properties, a heat-resisting thermosetting resin member having low friction properties, or a resin member having a Barcol hardness (A type) of 40 degrees or less is exposed at one or more surfaces of each of the guide lugs, the surface or surfaces contacting other member.

Abstract: An endoscope system comprises a plurality of endoscope components including at least one endoscope light source apparatus for supplying illumination light to an endoscope and at least one video signal processing unit for processing video signals provided by the endoscope, a main control unit for controlling the plurality of endoscope system components, and a main operational instruction unit connected to the main control unit and used to operate the plurality of endoscope system components. The main operational instruction unit includes a display capable of selectively displaying operational instruction input screens associated with functions possessed by the plurality of endoscope system components.

Abstract: A composite rubber article is obtained by joining a rubber composition based on a brominated p-methylstyrene/isobutylene copolymer to a different material such as a plastic, inorganic and metallic material through a di-, tri- or tetra-alkoxysilane compound. The copolymer is firmly joined to the different material. The invention is applicable to the manufacture of composite rubber articles such as tires, high-pressure hoses, and pneumatic springs.

Abstract: A printing apparatus such as a printer of the type using a type wheel includes two guide members which extend between a pair of side frames and each of which is fixed by riveting. A carrier is slidably mounted on the guide members. A carriage loaded with a type wheel and others is mounted on a carrier in such a manner as to be rotatable by 90 degrees between a predetermined print position and a wheel replace position behind the print position. A sensor for determining the presence/absence and the kind of a type wheel loaded in the carriage is provided.

Abstract: A printing device such as a printer of the type using a type wheel in which a carriage is loaded with a printing mechanism and movable along a carrier to allow the printing mechanism to print out data on a paper, which is wrapped around a platen. The carrier and/or the carriage is produced by press-forming a single sheet metal to cut down the production cost and the number of structural elements of the printer.
