Title: Dynamic pressure type bearing device
Inventor: MIZUGUCHI SHINICHI
IPC: F16C17/02
Filed: 1992-05-08
Abstract: PURPOSE:To reduce fluctuation of bearing rigidity and bearing loss to prevent drift of power consumption in a dynamic pressure type bearing device for a plygon mirror drive motor for a laser printer and the like, by constituting an outer cylinder of a material having a thermal expansion coefficient smaller than that of a shaft body material. CONSTITUTION:A thermal expansion coefficient of a material of an outer cylinder 5 is determined smaller than that of a material of a shaft body 1. For example, brass is used for the outer cylinder 5 while aluminum for the shaft body 1. With this constitution, a radial bearing clearance determined for room temperature is enlarged under low temperature, and consequently, offsets increase of dynamic pressure and bearing loss due to increase of oil viscosity. Inversely, the clearance is decreased under high temperature to offset decrease of dynamic pressure loss due to decrease of the oil viscosity.

Inventor: ISHIKAWA HIROSHI
IPC: H01S5/00
Filed: 1985-05-29
Abstract: PURPOSE:To improve current blocking performance of a buried region and obtain a high laser beam output by laminating the first other conductive type semiconductor layer with a high impurity concentration, the second other conductive type semiconductor layer with an impurity concentration lower than the first one and the one conductive type semiconductor layer successively in this order from the substrate side in the buried region. CONSTITUTION:A buried region 7 which occupies both sides of a stripe shape mesa 6, which is formed on the one conductive type semiconductor substrate 1 containing a light emitting part of double-hetero structure, is so constituted as to include the first other conductive type semiconductor layer with a high impurity concentration, i.e. a current blocking layer 8a, the second other conductive type semiconductor layer with an impurity concentration lower than that of the current blocking layer 8a, i.e. a current blocking layer 8b and the one conductive type semiconductor layer, i.e. a current blocking layer 9 which are laminated from the substrate 1 side in this order. If the impurity concentration of the current blocking layer 8b is reduced, the resistance of the layer 8b against the current flowing in from the mesa 6 becomes sufficiently high and, if the impurity concentration of the current blocking layer 8a is increased, a rising voltage between the layer 8a and the substrate 1 side can be sufficiently high so that the thyristor operation can be suppressed. With this constitution, a high laser beam output can be obtained.

Title: Semiconductor device
Inventor: USUKI TATSUYA
IPC: H01L29/68
Filed: 1992-05-08
Abstract: PURPOSE:To enable a semiconductor device to operate at a high speed by only controlling signal carriers while removing the other carriers from a space where carriers are present. CONSTITUTION:Electrodes 3 and 5 are set highest in potential, and an electrode 4 is so set in potential as to enable a traveling layer 1 of ballistic electrons conducive to signals to be kept intermediate in potential. A current flowing through the electrodes 3 and 5 is set higher in intensity as compared with a current which flows through an inlet 2. Ballistic electron injected through the inlet 3 are absorbed into the electrode 3, and even ballistic electrons scattered in the traveling layer 1 are quickly absorbed into the electrode 3 or the electrode 5. That is, electrons other than electrons directly conducive to signals are removed in the ballistic electron traveling layer 1. By this setup, by the potential of the electrode 4, a semiconductor device can be protected against an adverse effect caused by the variation of the electrodes 3 and 5 in potential.

Title: Layout device
Inventor: OKADA MASAO
IPC: G06T11/60
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To provide a layout device of high accuracy which can simplify its job by deforming and displaying an object in response to the selected one of plural constraint conditions. SOLUTION: A segment 27 is set at a layout object image 21, and the layout of the image 21 is carried out. In such cases, the segment 27 is pointed when a control point (start point) 23 and a control point (end point) 25 are pointed. Then the segment 27 is moved by the movement of the point 25 and the image 21 is deformed. Meanwhile, an operator points both points 23 and 25 against the image 21 and designates 'variable power' among the constraint buttons. The point 25 can move only on a circular arc centering on the point 23 even though the operator tries to move the point 25. When a point is decided as an end point on the circular arc, the image 21 rotates by the rotation of the segment 27. Thus, the image 21 is laid out with high accuracy when the segment 27 and the constraint condition of the segment 27 are given to the image 21.
