摘要： A band-like raw material which becomes a contact plate is supplied to a position between an upper mold and a lower mold as these molds are closed, a convex part for the contact with the lower mold is engaged with a concave part for contact with the upper mold, by which, simultaneously punching out the contact part onto a part of the band-like raw material, the band-like raw material is cut to a predetermined length between edge parts to form the contact plate. At this time, a tip of a press pin on which the concave part is formed is brought into direct contact with a central part of the band-like raw material. A resin is injected into the mold cavities to form a push rod integrally with the contact plate, and the central part of the contact plate is deformed in the concave part to provide a stopgap.

摘要： Analysis of an electromagnetic field in a region including an electric conductor having an arbitrary shape is efficiently and accurately performed with a computer. A value of electric potential at a predetermined portion of the electric conductor or a value of the normal component of an electric current density vector to the cross section of a predetermined portion of the electric conductor is used as an initial condition. The distribution of exciting current density vectors in the electric conductor is obtained form the initial condition so as to meet the condition of continuity of electric current.

摘要： Shaft holes 12 and 22 are formed on each pivot portion of a switch case 10 having an unfolded fan shaped concave body 11. A stationary contact base 20 covers the concave body, and a corresponding end portion of a shaft holder 40 are fitted into the respective holes to rotate freely. In addition, positioning through-holes 18 and 27 are formed at each corresponding portion of the switch case 10 and the stationary contact base 20. Either the switch case 10 side or the stationary contact base side 20 is set on an assembly jig 80 toward these shaft holes 12 and 22 and the positioning holes 17 and 27. As a result, the lever 72 can be engaged from either side of the switch case 10 or the stationary contact base 20.
