Abstract:
A method for controlling a power-shift transmission comprising controlling a vehicle travel speed by simultaneously slipping two or more clutch packs associated with opposing directions of vehicle travel and adjusting an engine speed, according to a programmed response associated with a change in one or more of the engine speed, a torque converter slip, a selected direction of vehicle travel, and an accelerator position.
Abstract:
A semiconductor package includes at least four lead frames each having an extending portion and a connecting portion, a heat dissipation plate having a top surface and a bottom surface, at least one semiconductor chip positioned on the top surface of the heat dissipation plate. At least one conductive wire electrically connects the chip to the lead frames. An encapsulation covers the lead frames, the heat dissipation plate, the semiconductor chip, and the conductive wires, while the bottom surface of the heat dissipation plate and the extending portions of the lead frames are exposed.
Abstract:
A system and method for manufacturing multiple-gate semiconductor devices is disclosed. An embodiment comprises multiple fins, wherein intra-fin isolation regions extend into the substrate less than inter-fin isolation regions. Regions of the multiple fins not covered by the gate stack are removed and source/drain regions are formed from the substrate so as to avoid the formation of voids between the fins in the source/drain region.
Abstract:
A phase change memory structure and method for forming the same, the method including providing a substrate comprising a conductive area; forming a spacer having a partially exposed sidewall region at an upper portion of the spacer defining a phase change memory element contact area; and, wherein the spacer bottom portion partially overlaps the conductive area. Both these two methods can reduce active area of a phase change memory element, therefore, reducing a required phase changing electrical current.
Abstract:
The present invention discloses a transformer, mounted on a circuit board, including a winding set having a bobbin, a primary winding and a secondary winding, wherein the primary and the secondary windings are wound on the bobbin, and the primary winding has at least a first output terminal; a magnetic core set including a first magnetic core and a second magnetic core, wherein the winding set is sandwiched in between the first and the second magnetic cores; and an insulation base including an accommodation space and at least a pin, wherein the winding set and the magnetic core set are accommodated in the accommodation space, and the first output terminal of the primary winding is connected with the pin for further electrically connecting to the circuit board.
Abstract:
A receptacle connector is adapted for receiving a plug connector which includes a casing and a plurality of plug terminals disposed in the casing. The receptacle connector includes a printed circuit board and a shell mounted on the printed circuit board. Portions of a front edge of the printed circuit board are recessed inward to form two fixing grooves with a tongue formed therebetween. A plurality of golden fingers are formed on two opposite surfaces of the tongue. The shell has a top plate, a bottom plate opposite to the top plate and two side plates connecting the top plate to the bottom plate. A space is formed among the top plate, the bottom plate and the side plates and receives the tongue. The side plates are restricted in the fixing grooves. The plug connector is inserted into the space with the plug terminals electrically abutting against the golden fingers.
Abstract:
A dual mode control system for a hydraulic circuit (200) having a variable displacement pump (216) includes at least two actuators, each controlled by a respective valve. The valves are connected in series with a pressure sensor (250) measuring a pressure of fluid between the first valve (224) and the second valve (234) and relaying a signal to the electronic controller (202). The electronic controller (202) operates in a first mode, varying the displacement of the pump (216) based on a command signal operating at least one of the valves, and operates in a standby mode, varying the displacement of the pump (216) based on the signal from the sensor, when both valves are in their respective neutral positions.

Abstract:
A foldable wheel seat has a base, an operating bar, a first rotating shaft and two wheel axles. The base has a groove formed in a top face of the base. The operating bar is mounted pivotally in the groove of the base. The first rotating shaft is mounted rotatably in the base and has at least one end and two pulling segments. The at least one end of the first rotating shaft is extended into the groove of the base and is securely connected to the operating bar. The pulling segments are mounted on the first rotating shaft and each pulling segment has two pulling tabs. The wheel axles are mounted rotatably in the base and are perpendicular to the first rotating shaft and below the pulling segments of the first rotating shaft. Each wheel axle has an engaging block, at least two wheels, a holding panel and a torsional spring.
