Abstract:
Assembly workability of an electric compressor to which an inverter circuit section and a filter circuit section are attached is improved. The inverter circuit section (3) includes an inverter control board (17), a sleeve assembly (18), and a power module (14). The inverter control board, the sleeve assembly, and the power module are integrated. The filter circuit section (4) includes a filter circuit board (66) and a support member (67). The filter circuit board (66) and the support member (67) are integrated. The inverter circuit section and the filter circuit section are structured to be capable of being stored each individually within an inverter storing section (8) from the same direction and detachably attached to the housing (2).
Abstract:
A surface mountable, toroid magnetic device is provided, the device having a potting filling the central hole of the toroid. The potting extends axially beyond the base of the toroid to form a contact surface which, in use, contacts a mounting body for the device. Heat generated by the device flows by conduction through walls of the toroid defining the central hole into the potting and then through the contact surface into the mounting body.

A semiconductor device includes a semiconductor element, a circuit board, metal wires, and an expanding member. The circuit board has an upper surface and a lower surface opposite the upper surface. The metal wires arc formed on at least one of the upper surface and the lower surface. At least two connection terminals are formed in a terminal formation surface of the semiconductor element which is disposed so as to face the upper surface of the circuit board. The expanding member is fixed to the terminal formation surface of the semiconductor element, has a larger coefficient of linear thermal expansion than the semiconductor element, and has a size larger than the interval between adjacent two of the at least two connection terminals.
Abstract:
A low power voltage control circuit for use in space missions includes a switching device coupled between an input voltage and an output voltage. The switching device includes a control input coupled to an enable signal, wherein the control input is configured to selectively turn the output voltage on or off based at least in part on the enable signal. A current monitoring circuit is coupled to the output voltage and configured to produce a trip signal, wherein the trip signal is active when a load current flowing through the switching device is determined to exceed a predetermined threshold and is inactive otherwise. The power voltage control circuit is constructed of space qualified components.

Abstract:
Embodiments of the invention relates to a process and assembly for a dual sided and staggered connector arrangement on a substrate. Surface mount connector technology is employed to enable a flush connection of connector leads to the surface of the substrate. Retaining pins are provided with each connector and are sized to be received by the substrate, but not to extend through the substrate. The retaining pins are sized and configured to hold each connector in a set position, while mitigating interference with an opposing side of the PCB.
