Abstract:
The present invention relates, in general, to an optical pickup actuator and, more particularly, to an optical pickup actuator, in which a depression (120) is formed in a center portion of a rear surface of a wire holder (100) to be depressed, and the position of a bobbin (20) is adjusted by straining wires (30) while a center portion of a printed circuit board (200), closely attached to the rear surface of the wire holder, is pressurized using a control screw (300) to allow the printed circuit board to be arcuately deformed.
Abstract:
A method for making a supporting body (1) for the lock of a motor vehicle, comprises the steps of: forming an intermediate element (8) made of electrically insulating material provided with conductive paths (3); setting the intermediate element (8) inside a mold (23) for forming the supporting body (1); and injecting electrically insulating material in the mold (23) for carrying out co-molding of the supporting body (1). The intermediate element (8) and the conductive paths (3) are made independently, and the conductive paths (3) are fixed on opposite faces (9, 10) of the intermediate element (8) by constraint means (15, 16) of a mechanical type.
Abstract:
The electrical connecting element includes an essentially stiff core, essentially mechanically stiff and printed circuit boards and/or high density interconnects with conductor paths serving as interconnects. The core includes two parts (1, 3) that can be fixed to each other. Between the two parts, a cavity (101) can be formed. Components (103) producing a lot of heat or requiring protection from environmental influences can be placed in the cavity.
Abstract:
A heatsink for a printed circuit board (PCB) overlies most or all of the board. It is clamped tightly to the board with its board-facing surface in close proximity to the heat-generating components on the board. A pliant, thermally-conductive dielectric layer is sandwiched between the PCB and the facing surface of the heatsink. Lands at various heights are formed on the heatsink surface facing the PCB to be in good heat-conducting proximity to the surfaces of heat-generating circuit components of various heights on the PCB.
Abstract:
Methods and apparatus for increasing the yield achieved during high density interconnect (HDI) production. In particular, processes in which panels are tested to identify good cells/parts, good cells are removed from the panels, and new panels created entirely of identified/known good cells allow increases in the number of layers used in a HDI without incurring the decrease in yield normally associated with such a layering process.
Abstract:
A power distributor having a power distribution circuit, and a housing 22 in which the power distribution circuit is housed, and a method of connecting a control circuit board 18 to the power distributor. A board support portion 32 for supporting the control circuit board 18 in an erect state is provided in the housing 22. The control circuit board 18 and the power distribution circuit are connected to each other through a wiring material 30 in the condition that the control circuit board 18 is supported by the board support portion 32. Then, the control circuit board 18 is toppled over to thereby be housed in the housing 22.
Abstract:
A structure for highly precisely and easily mounting an electronic circuit unit on a mother board without defective soldering, comprising a circuit board 3 provided with extending portions 3d having terminal patterns 8 formed thereon, a housing 2 for containing the circuit board 3 while permitting the extending portions 3d to protrude, and a mother board 5 having, formed therein, through holes 5a in which the extending portions 3d are to be inserted, having, formed thereon, wiring pattern (not shown) that is to be electrically connected to the terminal patterns 8, and permitting the extending portions 3d to be inserted in the through holes 5a so that the housing 2 is placed thereon. The circuit board 3 is provided with a protruded portion 3e which extends separately from the extending portions 3d and pushes the terminal patterns 8 onto the wiring pattern of the mother board 5. The mother board 5 is provided with an insertion hole 5b in which the protruded portion 3e is to be inserted being slightly deviated from the positions of the through holes 5a in which the extending portions 3d are to be inserted.
Abstract:
A curved portion 1g of a lead line set 1e is received in a recessed portion 13d that is formed in an inner face 13c of a base piece 13 in the open state. An inner face 17a of a first folded piece 17 is folded on the inner face 13c of the base piece 13, and the curved portion 1g of the lead line set 1e is sandwiched between the base piece 13 and the first folded piece 17. Thereafter, an inner face 21a of a second folded piece 21 is folded on an outer face 17e of the first folded piece 17, and the lead line set 1e portion that is slightly nearer the distal end than the lead line set 1e portion that is folded along a folding line X is sandwiched between the first and the second folded pieces 17 and 21.
Abstract:
A first casing (11, 12)includes a first end (30, 31). A second casing (11, 12) is mated with the first casing (11, 12). The second casing (11, 12) includes a second end (30, 31) facing the first end (30, 31). A flexible circuit member (23) is housed between the first and second casings (11, 12). The circuit member (23) is drawn out from the first and second ends (30, 31). The circuit member (23) is retained between the first and second ends (30, 31) under pressure.
Abstract:
A method of manufacturing a laminate obtained by laminating a plurality of plate members such as wiring plates (1) and prepregs (2), comprising: a step of temporarily fixing the plate members by a grommet (3) having plural resin filling holes (9) formed on the side surface thereof to obtain a temporarily-fixed laminate (5); and a step of heating and pressurizing the temporarily-fixed laminate (5) to fill the resin melted from the prepregs (2) of the temporarily-fixed laminate (5) through the resin filling holes (9) of the grommet (3) into the throughhole (6) of the grommet (3).
