Abstract: A power semiconductor device includes an insulating substrate on which a first conductor layer is arranged on one surface, a first conductor that is connected to the first conductor layer via a first connecting material, and a semiconductor element that is connected to the first conductor via a first connecting material. When viewed from a direction perpendicular to an electrode surface of the semiconductor element, the first conductor includes a peripheral portion formed larger than the semiconductor element. A first recess is formed in the peripheral portion so that a thickness of the first connecting material becomes thicker than other portions.

Abstract: A spindle motor includes a rotary unit, a bearing mechanism, a stator, a base member, and a connector connected to a leader line extending from the stator through a communication hole of the base member. The connector includes a pedestal and a metal pin. The leader line is connected to a first pin terminal of the metal pin on a hole-positioning lower surface of a hole-defining portion of the pedestal. An upper surface of the metal pin is separated from the pedestal at a specified separation position between the first pin terminal and a second pin terminal. A connection position of the first pin terminal and the leader line on the hole-positioning lower surface is covered with an adhesive agent. The periphery of a gap between the metal pin and the pedestal over an extent from the first pin terminal to the separation position is sealed by the adhesive agent.

Abstract: A hermetically sealed connector for a glove box and a method for exchanging such connectors in which leakage of radioactive material from within the glove box is minimized and an auxiliary glove box is not needed to exchange the connectors. The connector is formed as a cylindrical member having a flange portion hermetically sealed to a packing provided in a through hole in the wall of the glove box. To exchange connectors, a nut is removed from the outer end of the old connector and a tube is screwed thereto. The other end of the tube is fitted to the inner end of the new connector. The tube is then shoved through the packing until the flange of the new connector aligns with the packing. The tube is then removed from the inner end of the new connector and a nut is screwed on in replacement for the tube.
