A crystal plane substrate is prepared having a main surface which has an offset angle in a range of +/−0.1% with respect to a C-plane or a crystal plane equivalent to the C-plane; and during a time period in which a III-source gas and a V-source gas are supplied to grow a III-V group nitride semiconductor layer, carbon tetrabromide (CBr4), which is a carbon source gas, is supplied so as to introduce carbon into a V-group atom layer.
Slip ring apparatus for electric rotating machine
A restricting member is provided that is in contact with respective bent lead portions of a long-sized lead and a short-sized lead and imparts a tension to linear lead portions thereof in a mold for insert molding. The restricting member reliably prevents the leads from displacement and deformation resulting from the pressure of the resin at the time of insert molding, and allows the long-sized lead and the short-sized lead to be disposed at proper positions in a molded body.
Electrical connector with grounding plate retained therein
An electrical connector includes a terminal module unit with contacts and grounding plates thereof. The terminal module includes an insulative base and an insulative mating tongue forwardly extending therefrom. The mating tongue forms opposite mating surfaces. The contacts includes the contacting sections on the mating surfaces and the connecting legs. The mating tongue includes a root section adjacent to the base. The grounding plates unit covers the root section in an embedded manner. The grounding plate includes a planar body exposed upon the mating surface, and a pair of fixing side arms extending from two opposite ends of the planar body and equipped with corresponding latching hooks to secure to the semi-finished root section before the final insert-molding process is applied.
Processor loading system
A component loading system includes a board having a socket. A first base member is secured to the board through a plurality of first heat dissipater coupling posts. A first securing member is moveably coupled to the first base member. A second base member is secured to the board through a plurality of second heat dissipater coupling posts. A second securing member is moveably coupled to the second base member. A loading member is moveably coupled to the first base member. A heat dissipater is operable to be coupled to the plurality of first heat dissipater coupling posts and the plurality of second heat dissipater coupling posts. The loading member is operable to be secured to the board by moving the first securing member into engagement with the second base member and moving the second securing member into engagement with the first base member.
Control apparatus, connector, and laminated capacitor for connector
Provide are a control apparatus, a connector, and a laminated capacitor for connector which are small and light and in which the capacitor capacitances on the terminals can be easily adjusted. A laminated capacitor 113 is integrally formed by laminating: a terminal dielectric sheet 123a on which is printed a terminal circuit pattern P10a having terminal connecting patterns P12a electrically connected to a plurality of connection terminals 111 and terminal-side electrode patterns P11a connected to the terminal connecting patterns P12a; and a ground dielectric sheet 123b on which is printed a ground circuit pattern P10b having ground-side electrode patterns P11b disposed to face the terminal-side electrode patterns P11a and a ground pattern P12b connected to the ground-side electrode patterns P11b.
Plug connector protecting against overvoltage discharge
A plug connector for protecting an electrical system, in particular an electronic device, a semiconductor component or cable harness, against overvoltage discharge, includes contact pins embedded in a plastic body, wherein the plastic has an area between the contact pins that exhibits an electrical resistance with an essentially electrically insulating property within an operating range up to a limiting voltage, and further exhibits a diminished electrical resistance above the limiting voltage, allowing a discharge of the overvoltages between the contact pins. A method of manufacturing the plug connector and its use are also disclosed.
Insulated grounding hub locknut unit
An insulated grounding hub locknut for securing a conduit connector or threaded conduit has a locknut and a snap-on insulator. The outer surface of the locknut has grounding-lug mounting pads and raised members, and the inner surface has internal threads for screwing onto threads of conduit connector or a threaded end of the electrical conduit. The snap-on insulator has an annular body with an end face, the outer side of which has a cylindrical surface arranged to snap onto the raised members of the locknut. The cylindrical surface has open slots to receive the mounting pads on the locknut. The end face also has an inner cylindrical sleeve arranged to be placed inside the throat of the first cylindrical member of conduit connector.
