  • Patent number: 6094349
    Abstract: An electrical device has a printed-circuit board secured to a cover of the electrical-device housing, as well as a heat-dissipation mat arranged on a housing wall. The cover secured to the housing, as well as guideways of the housing, in which guideways the printed-circuit board is received, exert a tension force on the printed-circuit board, because of which electronic components arranged on the printed-circuit board, under conditions of intimate contact with the heat-dissipation mat, are embedded into the heat-dissipation mat. This is achieved by introducing the printed-circuit board in inclined position into the housing and, shortly before it reaches its final position, swivelling the printed-circuit board toward the wall of the housing having the heat-dissipation mat.

  • Patent number: 6034571
    Abstract: An oscillator includes a multi-layered base. Circuit patterns are formed on a first main surface and the inside of the multi-layered base. Holes through which wiring patterns of the individual layers of the base are connected are formed within the multi-layered base. Electronic components are mounted on the first main surface of the multi-layered base. First and second reverse electrodes, which serve as external terminals to be connected to an external source, are formed on a second main surface of the multi-layered base. The first reverse electrode serves as a ground electrode, and the second reverse electrodes serve as terminal electrodes. The reverse electrodes are electrically connected to the circuit patterns via the holes. The reverse electrodes are located farther inward than the lateral surfaces of the multi-layered base. A shield cover is placed to tightly cover the first main surface of the multi-layered base.

  • Patent number: 6017004
    Abstract: A computer card lock-down device is formed from a bowed piece of an insulating plastic, metal coated with an insulating plastic or the like. A first portion of the lock-down device is formed to be flat and has a screw connection. The rest of the lock-down device has an approximately U-shaped cross-section. At a second portion, the U-shaped cross-section forms a slot for engagement with an upper edge of the card. In use, the first portion is held against the face plate of the card with the same screw used to secure the card in the expansion slot, and the second portion engages with the card. The lock-down device can be bowed sufficiently that it contacts the lid of the computer CPU case. The lock-down device exerts a spring force on the card to prevent the card from coming loose from the expansion slot.
