A mounting apparatus for a PCI card includes a mounting bracket, a securing piece adapted to attach the PCI card to the mounting bracket and a securing member. The mounting bracket has a base and a blocking plate perpendicular to the base. The securing member includes a pressing piece and a securing piece rotatably attached to the pressing piece. The mounting piece includes a mounting end. The securing piece includes a securing portion. The securing piece is capable of engaging with an inside surface of the mounting bracket by rotating the securing piece relative to the pressing piece, thereby sandwiching the mounting end of the securing piece between the blocking plate and the pressing piece.

The present invention provides a junction box configured to be used with a photovoltaic module. The junction box comprises a central connecting portion adapted to receive metallic ribbons extended from the photovoltaic module, and a peripheral portion enclosing the central connecting portion. The peripheral portion comprises a plurality of recesses defined therein, and each of the recesses is adapted to receive a snap ring of a cable. Further, each of the recesses has an opening to the exterior of the junction box, and a channel communicating with the central connection portion. The opening and the channel of the recess define a longitudinal axis extending toward the central connection portion. The junction box of the present invention allows cables to be coupled to the photovoltaic module in multiple directions.

A computer enclosure includes a chassis and a frame. The chassis includes a chassis bottom wall and two chassis sidewalls located on the chassis bottom wall. A positioning post is located on each chassis sidewall. Each chassis sidewall defines a positioning hole. The frame includes a mounting bracket and a retaining bracket integrated with the mounting bracket. The mounting bracket defines a through opening, and includes two mounting bracket sidewalls. Each mounting bracket sidewall defines a slot and a fastening hole. Fasteners are engaged in the positioning holes and the fastening holes, to secure the frame to the chassis. The retaining bracket defines a holding space, configured for receiving a disk drive. The holding space communicates the through opening. When the positioning posts of the chassis are engaged in the slots of the mounting bracket, the positioning holes are aligned with the fastening holes of the mounting bracket.

A printed circuit board includes a substrate including a first surface and a second surface opposite to the first surface, a pair of first pads positioned on the first surface and the second surface, and a plurality of insulating areas. The substrate defines a through hole and a plurality of vias extending from the first surface to the second surface. Each of the pair of first pads surrounds the through hole. The insulating areas are adjacent to the first pad to divide a reference metal layer of the substrate adjacent to the first pads into a plurality of metal strips to reduce heat dissipation area of the reference metal layer adjacent to the first pads. The vias are adjacent to the metal strips to supply extra heat to molten solder on the first surface in a wave-soldering process.

A buckling device for electronic heating element, inter-assembled with a thermally conductive body, includes a cooling plate, a pair of fixing legs bent-and-extended from the cooling plate and formed under the cooling plate and a fixing arm bent-and-extended from the cooling plate and formed under the cooling plate. On the cooling plate, a plurality of slots are stamped, one side of each of which is bent and configured into a cooling piece. The thermally conductive body is fixed by being sandwiched between the fixing arm and the cooling plate. Thereby, the buckling device can be used in a thin electronic device to reduce its assembly and machining costs on a large scale.

Power regulator circuitry for programmable memory elements on programmable logic device integrated circuits is provided. The programmable memory elements may each include a storage element formed from cross-coupled inverters and an address transistor. Address drivers may be used to supply address signals to the address transistors. The power regulator circuitry may include an address power supply circuit that produces a time-varying address power supply voltage to the address drivers and storage element power supply circuits that provide time-varying storage element power supply voltages to the cross-coupled inverters in the storage elements. Unity gain buffers may be used to distribute a reference voltage from a bandgap voltage reference to the power supply circuits. The power supply circuits may use voltage dividers and p-channel metal-oxide-semiconductor control transistors.
