摘要： PROBLEM TO BE SOLVED: To improve the restriking characteristic by moving a heating front on a sintered body surface at a specified speed from one end of a flat plate-like sintered body to the other end thereof in a process of obtaining a sintered body. SOLUTION: When the current of not less than a specified value is shut off, the arc is stopped at one point or a plurality of points which are totally unpredictable, and a contact electrode can be abnormally melted and led to a shut-off limit. The abnormal melting forms a very large droplet to cause the rough surface of the contact electrode, degradation of the withstand voltage characteristic, the increase in the ratio of generation of restriking, and the abnormal consumption of a material. These disadvantages largely affects the non-uniformity of the material between micro areas mainly on the contact surface (the composition, components, the components and quantity of the sealed gas adsorbed or adhered to the contact surface, unevenness of the surface, etc.). To obtain a uniform surface with these material non-uniformity removed therefrom, a heating front is moved at the speed of 0.1-20 mm/second from one end of a sintered body to the other end thereof when the flat plate-like sintered body is heated.

摘要： PURPOSE:To enhance reliability and facilitate assembly by forming first and second contact portions by plating nickel, nickel-phosphorus alloy, copper and silver thereon, in order. CONSTITUTION:Contact portions 16a, 18b are provided in first and second energizing shafts 16, 18 made of annealed copper material, respectively. The contact portions 16a, 18b are formed by plating nickel, nickel-phosphorus alloy, copper and silver in order. Accordingly, even if the first and second energizing shafts 16, 18 are welded to a sealing fitting 12a and a bellows 19, or a sealing fitting 12b under such a heating condition as to use silver solder, nickel of the nickel layer alloys with copper of the copper base. Meanwhile, since solid-insolubility of nickel and silver eliminates a silver flow, the same contact resistance and surface oxidation as those in the case of silver plating can be obtained. It is thus possible to facilitate assembly and enhance reliability with high dimensional accuracy.
