Abstract: A mover assembly of a reciprocating motor includes: a mover body disposed at a gap between an inner stator and an outer stator; permanent magnets fixed at an outer circumferential surface of the mover body and reciprocally moved together with the mover body in a direction of an induction magnetic field between the inner stator and the outer stator; and a mixed member made of a fiber and a resin to cover and fix the permanent magnets. The permanent magnets are arranged at an outer circumferential face of the mover body, covered with the mixed member obtained by mixing a fiber and a resin, and hardened to be fixed. Therefore, the permanent magnets can be firmly and easily fixed at the mover body. In addition, by molding the mover body with a non magnetic and non-conductive material, leakage of the magnetic force of the permanent magnets can be prevented.

Abstract: A interconnect structure is inexpensively manufactured and easily insertable into a socket. The interconnect structure is manufactured by forming a sacrificial substrate with cavities that is covered by a masking material having openings corresponding to the cavities.

The interconnect structure is completed by first removing the masking material and sacrificial substrate. Ends of the wires are coupled opposite now-formed contact structures to a board. To complete the socket, a support device is coupled to the board to hold a tested integrated circuit.

Abstract: A Dry-Film resist formed of, for example, a photosensitive film is stacked on the electroconductive material and these portions, other than a projection electrode formation area, formed on a wiring board's electrode serving as a portion of a circuit pattern are masked with a mask. After this, the wiring board is exposed to light and, after the removal of the mask, a development process is performed, thus eliminating the Dry-Film resist on the wiring board at the portion other than the projection electrode formation area. Then the electroconductive material of the wiring board is etched under an etching process to provide a projection electrode having a bump with a pointed tapering end in vertical cross-section. Finally, the wiring board is exposed to a Dry-Film resist elimination solution to remove remaining Dry-Film resist from the projection electrode. And a plating process is performed on the electroconductive material to form a plated layer and hence complete the projection electrode.
