Motor-type power device

ActiveUS20090127954A1Suppress stirring resistance of oilEnsure performanceGearboxesGear lubrication/coolingEngineeringCentrifugal force
Due to a centrifugal force in a vehicle width direction due to turning of an automobile, oil in an electric motor housing chamber housing an electric motor and oil in a transmission housing chamber housing a reduction gear and a differential gear flows to-and-fro via oil communication passages that penetrate a partitioning wall. An opening on the transmission housing chamber side of the oil communication passages is spaced from the partitioning wall. Hence, when oil moves from the transmission housing chamber side to the electric motor housing chamber side, it is possible to prevent the oil quantity on the electric motor housing chamber side from increasing excessively and suppress an increase in resistance to oil stirring by a rotor of the electric motor while retaining a constant oil amount on the transmission housing chamber side to ensure lubricating performance for the reduction gear and the differential gear.

Manufacture method and device of three-dimensional workpiece

The invention provides a method and equipment using organic adhesive mixed solvent and powder to manufacture three-dimensional workpieces. The work principle is as follows: the raw materials are stirred into slurry, which is laid as a green compact thin layer that can disintegrate in disintegrant; the green compact thin layer can form a workpiece thin layer that does not disintegrate in the disintegrant after scanned by an energy beam; in such a cycle, the steps of laying the thin layer and energy beam scanning are repeated, and then the three-dimensional workpiece can be formed; and the disintegant is used for separating the green compact not scanned by the energy beam from the workpiece, thus remaining the needed three-dimensional workpiece. The invention is widely applicable to manufacturing plastic, metallic, ceramic and compound workpieces, can avoid the defects of a selective laser sintering method, can use fine and very thin powder and therefore, can manufacture a finished product which is better than that made in the traditional selective laser sintering method in surface roughness and texture fineness, in addition, through subsequent densified sintering, the metallic and ceramic workpieces can have the strength superior to that in the traditional selective laser sintering method.

Apparatus for production of crystal of group III element nitride and process for producing crystal of group III element nitride

A manufacturing apparatus of Group III nitride crystals and a method for manufacturing Group III nitride crystals are provided, by which high quality crystals can be manufactured. For instance, crystals are grown using the apparatus of the present invention as follows. A crystal raw material (131) and gas containing nitrogen are introduced into a reactor vessel (120), to which heat is applied by a heater (110), and crystals are grown in an atmosphere of pressure applied thereto. The gas is introduced from a gas supplying device (180) to the reactor vessel (120) through a gas inlet of the reactor vessel, and then is exhausted to the inside of a pressure-resistant vessel (102) through a gas outlet of the reactor vessel. Since the gas is introduced directly to the reactor vessel (120) without passing through the pressure-resistant vessel (102), the mixture of impurities attached to the pressure-resistant vessel (102) and the like into the site of the crystal growth can be prevented. Further, since the gas flows through the reactor vessel (120), there is no aggregation of an evaporating alkali metal, etc., at the gas inlet or the like, and such an alkali metal does not flow into the gas supplying device (180). As a result, the quality of Group III nitride crystals obtained can be improved.
