  • Patent number: 7029380
    Abstract: In order to improve a flatness of a work in single wafer type double-side polishing in which one wafer is polished with one carrier, a carrier larger in diameter than upper and lower surface plates that rotate is inserted between the surface plates, and a wafer smaller in diameter than the surface plates is held with the carrier. The carrier is rotated by plural eccentric gears that mesh with external gear teeth formed on the outer peripheral surface of the carrier at plural positions along a circumferential direction thereof and revolve around positions spaced from the centers as centers in synchronism with each other or one another at the plural positions of meshing. The carrier rotates about its center and moves circularly around the center of the surface plates spaced from the center thereof. The upper surface plate is reciprocated in a direction perpendicular to the central axis when required.

  • Patent number: 7024767
    Abstract: A method for making a terminal includes forming a reinforcement enclosed around the pieces of the distal end of the terminal to combine and connect the pieces. Thus, the pieces of the distal end of the terminal are connected closely by the reinforcement to form a compact conic body without forming an opening in the distal end of the terminal, so that the distal end of the terminal has a greater structural strength, thereby preventing the distal end of the terminal from being broken or worn out due to mutual hit when the distal end of the terminal is inserted into a female terminal in a misalignment manner.

  • Patent number: 7025664
    Abstract: An apparatus for planarizing a work piece includes an easily assembled work carrier. The carrier includes a carrier insert having a work piece bladder clamped to a carrier backing plate with a plurality of clamps to form a plurality of web plenums. The outer edge of the bladder is supported by a rib that is coupled to a carrier plenum. By adjusting the pressure in the carrier plenum, the pressure exerted on the edge of a work piece during a planarization operation can be adjusted. The carrier also includes a floating wear ring that surrounds the work piece bladder and a work piece mounted on that bladder. By adjusting the force exerted by the wear ring on a polishing pad, independently of the pressure exerted by the rib at the edge of the bladder, the material removal rate near the edge of the work piece can be controlled.

  • Patent number: 7016947
    Abstract: Configuring a segment identifier in a customer premise equipment (CPE) connected to a network. Several OAM loopback cells containing possible segment identifiers in the headers may be transmitted. If an accurate segment identifier is used, the corresponding loopback cell may be received again in the CPE as an end system at the other end of the virtual circuit may loopback the cell. Thus, the CPE may be configured with the segment identifier corresponding to the received loopback cell. Once configured, new additional cells may be transmitted with the configured segment identifier.

  • Patent number: 7013552
    Abstract: An electric motor having an armature which includes a coating of thermally conductive plastic applied in a conventional injection molding process. The armature also includes a fan which is integrally formed from the thermally conductive plastic applied to the armature. This completely eliminates the need to apply one or more coatings of a trickle resin to the armature. It also eliminates the need to separately form and secure a fan by a suitable adhesive to the armature, which together significantly simplifies the manufacturing and cost of the armature. The plastic coating also better fills the spaces between the magnet wires, thus promoting even more efficient cooling and better holding of the magnet wires stationary relative to one another. The thermally conductive plastic coating may be mixed with other suitable materials to provide a density approximately equal to the magnet wires. This eliminates the need to balance the armature after the injection molding step.
