Abstract: A high voltage capacitor is disclosed that comprises a grounding member (1), two through type capacitors (2 and 3), an insulating case (6) and insulating resin (71 and 72). The grounding member (1) has two raised portions (101 and 102) on which the through type capacitors (2 and 3) are secured. The insulating case (6) has two hollow cylindrical portions (61, 62) spaced apart by a distance D with their upper open ends joined to each other to form a recessed enclosure (63) in line with and following the inner diameter sections (611, 621) of the hollow cylindrical portions (61, 82) and their lower open ends fitted on the outer circumference of the raised portions (101, 102). The insulating resin (71 and 72) is provided around the through type capacitors (2 and 3) within the inner diameter sections (611, 621).

Abstract: A steel ball machining apparatus comprises a cylindrical ball storing vessel having an opening, a steel ball machining mechanism, a steel ball supply path for supplying steel balls to said machining mechanism from the opening in said vessel, a steel ball discharge path for discharging the balls from said machining mechanism, and an elevating conveyor is provided between the discharge path and the cylindrical vessel, the elevating conveyor having a ball receiving vessel which is adapted to move between a lower position in which the ball receiving vessel aligns with the discharge path and an upper position over the cylindrical vessel, a lifter of said ball receiving vessel, a ball return path provided at the upper position for feeding the balls from the ball receiving vessel over to the cylindrical vessel, the return path having a ball exit adapted to discharge the balls to said cylindrical vessel at radially different positions therein.

Abstract: A steel ball machining apparatus comprises a ball machining mechanism having a pair of machining plates which are adapted to oppose and rotate relative to each other, a steel ball storing vessel for supplying to and receiving from said polishing mechanism steel balls, a steel ball supply path provided between said machining mechanism and said steel ball storing vessel, a steel ball discharge path provided between said machining mechanism and said steel ball storing vessel adapted to discharge said steel balls to said vessel, and a set of parallel bars provided in at least one of said steel supply path and steel ball discharge path so as to eliminate foreign matter.

Abstract: A high-voltage through-type ceramic capacitor which is capable of exhibiting satisfactory heat resistance sufficient to ensure good operability of the capacitor even under severe conditions and being positively small-sized while ensuring its satisfactory operation. In the capacitor, at least one of an insulation case and an insulation cover is made of a material selected from the group consisting of polyethylene terephthalate and nylon 66. The capacitor further includes a pair of central conductors each including a fastening tab arranged in the insulation case, and the insulation case is formed at an upper portion thereof surrounding the fastening tabs into an upper enlarged section.
