摘要： In order to manufacture a dynamic pressure bearing device, there are provided a shaft member, and a thrust plate formed with a press-fitting portion into which the shaft member is press-fitted. At least two relief portions are formed in at least one of the press-fitting portion of the thrust plate and a part of the shaft member which corresponds to the press-fitting portion. The shaft member is press-fitted with the press-fitting portion such that the thrust plate extends perpendicular to an axial direction of the shaft member, while making the relief portions absorb press-fitting stress.

摘要： The invention provides an information processing apparatus and method and a providing medium by which editing of routing can be performed rapidly and readily. When a node which has no DEF name applied thereto is dropped into a route window, a routing editing tool provides a DEF name to the dropped node. When a node displayed in the route window or a scene graph window is dragged by a mouse and dropped to another node displayed in the scene graph window or the route window, the routing editing tool displays route candidates which can be set between the two nodes. When a user selects one of the displayed route candidates, the routing editing tool sets the selected route candidate as a route between the nodes.

摘要： In a nitride compound semiconductor laser including an active layer sandwiched by semiconductor layers of different conduction types on a sapphire substrate, layers of polyimide for current blocking and light confinement are formed on side surfaces of a mesa-type current confining structure with and under the p-side electrode. The laser ensures efficient, uniform carrier injection into the active layer, suppresses higher-order modes other than the fundamental transverse mode, and thereby promises a high reliability ensuring continuous pulsation under a low threshold current and a low operation voltage with low noise characteristics.

摘要： Cleaning apparatus provide for the cleaning of a workpiece by first immersing the workpiece in a cleaning tank having a cleaning liquid therein for a predetermined period of time, removing the workpiece from the cleaning tank, moving the workpiece through air for a pre-selected period of time, and supplying the workpiece to a drying device which then dries the workpiece. As the workpiece is moved through the air, the workpiece may be vibrated, moved at an incline then a decline, and/or have air blasted at it, so that any liquid, e.g. rinsing solution, remaining thereon is caused to fall off, such occurring prior to the drying of the workpiece by the drying device.

摘要： After p-type gallium nitride compound semiconductor layers, to which p-type impurity is added, are formed by virtue of chemical vapor deposition, the p-type gallium nitride compound semiconductor layers are thermally annealed at more than 400.degree. C. or more than 700.degree. C. while supplying a flow of an inert gas in parallel to a substrate surface at a predetermined flow rate or more. Otherwise, the p-type gallium nitride compound semiconductor layers are thermally annealed at more than 400.degree. C. or more than 700.degree. C. in an inert gas atmosphere having a predetermined pressure or more. According to the annealing process, the p-type impurity can be more effectively activated, so that p-type gallium nitride compound semiconductor layers which have fewer crystal defects, etc. and have lower resistivity can be formed.
