  • Patent number: 9797478
    Abstract: An electrically powered gear box for a semitrailer stabilizer, comprising a gear box housing; the housing is internally provided with a drive gear (10), a power output shaft (2), and a clutch mechanism ensuring transmission connection or disengagement between the drive gear (10) and the power output shaft (2); the housing is externally provided with a motor (20); and the shaft of the motor is in a transmission connection with the drive gear (10). The electrically powered gear box for the semitrailer stabilizer can be manually or electrically controlled. In the case of electrical control, the clutch mechanism causes the drive gear (10) to be in a transmission connection with the power output shaft (2); upon activating the motor (20), the motor (20) drives the power output shaft (2) to rotate via the drive gear (10) and the clutch mechanism, thus ensuring easy operation.

  • Publication number: 20170140470
    Abstract: An indirect data object association module performs an indirect data object association based on detecting a user interaction with an interface for determining data objects associated with a selected data object. The module generates a direct association interface object that lists data objects directly associated with the selected data object and accesses data corresponding to data objects associated with the data objects listed in the direct association interface object. An indirect data object association is performed based on the selected data object, its directly associated data objects and the accessed data. The module generates an indirect association interface object to list data objects indirectly associated with the selected data object and links the indirect association interface object to the direct association interface object.

  • Patent number: 9653545
    Abstract: A MOSFET disposed between shallow trench isolation (STI) structures includes an epitaxial silicon layer formed over a substrate surface and extending over inwardly extending ledges of the STI structures. The gate width of the MOSFET is therefore the width of the epitaxial silicon layer and greater than the width of the original substrate surface between the STI structures. The epitaxial silicon layer is formed over the previously doped channel and is undoped upon deposition. A thermal activation operation may be used to drive dopant impurities into the transistor channel region occupied by the epitaxial silicon layer but the dopant concentration at the channel location where the epitaxial silicon layer intersects with the gate dielectric, is minimized.

  • Patent number: 9627476
    Abstract: A semiconductor device and method of formation are provided herein. A semiconductor device includes a fin having a first wall extending along a first plane, the fin including a doped region defining a first furrow on a first side of the first plane. A dielectric is disposed within the first furrow, such that the dielectric is in contact with the first furrow between a first end of the dielectric and a second end of the dielectric. The first end is separated a first distance from the first plane. The dielectric disposed within the furrow increases the isolation of a channel portion of adjacent fins, and thus decreases current leakage of a FinFET, as compared to a FinFET including fins that do not include a dielectric disposed within a furrow.
