Abstract: PURPOSE:To uniformly fuse the whole body by integrally forming an uncross- linked thermoplastic resin layer having a heating wire provided therein on the inside of a cross-linked thermoplastic resin layer of a joint body to make contact with bodies to be connected in such a manner that the center part is thickened and the both end parts are thinned. CONSTITUTION:In an electrofusion joint 1, an uncross-linked polyolefin resin layer 3 having a heating wire 4 provided in the inner part or on the inner surface or outer surface is integrally formed on the inner both sides of a cross- linked polyolefin resin layer 2 in such a manner as to make contact with connected bodies 5, 6. In this case, the uncross-linked polyolefin resin layer 3 is formed in such a manner that the center part is thickened and the both end parts are thinned. Polyolefin tubes which are the bodies 5, 6 to be connected are inserted up to a butt part 7 from the both sides of the joint 1, and the heating wire is energized to melt the uncross-linked polyolefin layer 3, which is then fused to the bodies to be connected and integrated therewith. Hence, the whole body can be uniformly fused to improve sealing property and heat- resisting strength.

Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide an intake/exhaust valve driving control device for an internal combustion engine which can prevent partial abrasion of surfaces of engagement grooves by repeating movement of pins for transmitting torque while always sliding in the engagement grooves. SOLUTION: A driving shaft 21 is rotatated synchronously to the rotation of an engine. A cam shaft 22 is arranged coaxially with the driving shaft 21. A flange 27 formed with an engagement groove 30 is arranged on an end of the cam shaft 22, while a flange 32 formed with an engagement groove 33 is arranged on the side of the driving shaft. Pins 36, 37 are projected from a circular disc 29 between the flanges 27 and 32 in opposite directions, and engaged with the engagement grooves on the flanges. The circular disc 29 are supported rotatably and oscillatably along a shaft perpendicular direction, and is oscillated according to an operation condition of the engine.

Inventor: NISHII TAKESHI
IPC: H01H1/58
Filed: 1988-03-28
Abstract: PURPOSE:To increase the widths of terminals for preventing a metal mold from being damaged by applying the simultaneous forming process of the terminals and a body with the bending process of the terminals, arranging the terminals such that the sides of the respective terminals face each other, the bent parts of the terminals are included in the body to be formed. CONSTITUTION:Terminals 31-33 are formed by punching a plate out under conditions where the basic part side locating inside the terminals 31-33 are connected with a hoop member. The terminals 31-33 are bent at 90 degrees and a body 1 is formed such that the bent parts thereof are surrounded, thereby increasing the widths of the terminals 31-33. In the simultaneous forming, the terminals 31-33 are bent before the body 1 is formed and surround in the body 1. It is thus possible to prevent the strength and accuracy of twisted parts from being lowered. Chamfering is applied to the portions to be inserted into insertion holes of metal molding. It is thus possible to prevent the metal molding from being damaged in forming the body on the terminals.
