Abstract: A base plate conveyor for supplying a base plate storage section at one end of a base plate conveyance passage to the conveyance surface of the passage or receiving the base plate from the passage to the storage section. The conveyor is characterized by including the base plate storage section in which a plurality of base plates can be piled so that the base plates are leant against the inside of the section and the conveyed surface of the base plates have a predetermined angle to the conveyance surface of the conveyance passage; and a base plate mover provided at the casing of the conveyor so as to automatically move the base plate from the storage section to the conveyance passage or from the conveyance passage to the storage section. The base plate mover includes a vertically swung arm member, which is swung vertically and translated so as to move the base plate between the base plate storage section and the base plate conveyance passage.

Abstract: A laminator for bonding a film onto a substrate is disclosed which comprises a film supply plate for supplying the film along a supply path, a film temporary bonding body and a film temporary bonding edge member for temporarily bonding the film in pressing contact with the substrate. The film temporary bonding edge member is detachably provided on the film temporary bonding body. A first heat insulator is interposed between the film temporary bonding body and the film temporary bonding edge member. The temporary bonding body is detachably provided at a leading end of the film supply path of the film supply plate. A second insulator is interposed between the film supply plate and the film temporary bonding body.

Abstract: A laminator for cutting a continuous thin film in a predetermined size and laminating same over a substrate is disclosed which comprises a stationary laminator body; a thin film supply member for supplying the continuous thin film to the substrate; a temporary bonding member for temporarily bonding a leading end of the continuous thin film within a pathway of thin film supply; and a support member for suppporting the thin film supply member and the temporary bonding member in such a manner that the thin film supply member and the temporary bonding member are movable toward or away from the substrate. The support member is mounted on the stationary laminator body. The laminator also includes a cutter for cutting the continuous thin film in a predetermined size. The cutter is secured to the laminator body in an area near the pathway of thin film supply between the thin film supply member and the substrate.

Abstract: A device for fixing a roller to a rotary shaft, particularly useful with supply and take-up rollers in a laminator device for printed circuit boards, in which only a single tightening operation is required to fix the roller to the shaft. A support member and a press member when assembled together fit inside an end of the roller. A manually rotatable screw threaded to the press member passes through a hole in the support and presses against a sleeve through which the shaft passes and which is press-fitted inside the support member. Guide plates hold the support member and press member in place.

Abstract: A noiseless lug tire which runs at a high speed under a heavy load and which satisfies the following conditions.(1) A ratio Wg/Wl is equal to or smaller than 1.0.(2) Each transverse groove for delimiting lugs is not inclined toward an opening of the transverse groove at the kickout side of each lug.(3) Each transverse groove is inclined toward the opening at the stepin side of each lug at an angle of at most 22.degree..(4) Each portion of a center line of the transverse groove in a substantially total region of a length L of the transverse groove is inclined with respect to the meridian line of the tire at an angle within a range from at most 15.degree. measured in a direction opposite to the inclination direction of the transverse groove as a whole to at most 60.degree. measured in the same direction as the inclination direction of the transverse groove as a whole.
