摘要： A bolt is provided with a head part and a shank part. The shank part includes a first constant diameter cylindrical part, a transition part, a cylindrical connection part, and a second constant diameter cylindrical part concentrically extending from the first constant diameter cylindrical part to the second constant diameter cylindrical part. The first constant diameter cylindrical part has a screw thread with a predetermined pitch formed on the side surface thereof. The transition part has a tapered shape and has a screw thread with a predetermined pitch formed on the side surface thereof. The cylindrical connection part has a diameter smaller than that of the first constant diameter part. The second constant diameter cylindrical part has a diameter smaller than the first constant diameter part, and has a screw thread with a predetermined pitch formed on the side surface thereof. The crest part of the screw thread formed on the side surface of the transition part is truncated.

摘要： A socket for an IC package includes a base member having a receptacle space for the IC package, a plurality of contacts arranged in parallel along the sides of the receptacle space of the base member. The contacts each have a contact portion for contact with a corresponding lead of the IC package received in the receptacle space. A spring portion urges the contact portion inwardly to obtain a contact pressure against a lead. A connecting shaft is pivotally supported vertically along each row of the contacts, and is associated with the contacts. A cover covers the base member, and the connecting shaft pivots by depression of the cover to displace the contact portion of each contact outwardly away from the corresponding lead of the IC package against a biasing force of the spring portion. The contact has a curved, first spring portion extending upwardly and inwardly from an inside edge of a plate portion. A second spring portion is bent inwardly from a front end of the first spring portion and is contiguous to the contact portion, and a projection is formed on an upper surface of the second spring portion. The connecting portion has an engaging recess for engagement with the projection and also has an engaging face for engagement with the portion behind the projection. The cover includes inclined surface for allowing the movable cams to move pivotally outwardly.

摘要： A wired circuit board is provided having enhanced reliability of electrical connection between a metal substrate and a shield layer to achieve significant noise reduction reliably. An insulating base layer is formed on the metal substrate, while resin layers are formed on the metal substrate with a predetermined space provided from the both widthwise sides of the insulating base layer. A conductor layer is formed having a predetermined wired circuit pattern on the insulating base layer. Thereafter, an insulating cover layer is formed on the insulating base layer in such a manner as to cover the conductor layer. Then, a shield layer is laminated on the metal substrate to cover the insulating cover layer and also is put in close contact with the resin layers at end portions thereof by a vacuum film-forming method or by plating.
