Abstract: PURPOSE:To prevent the corrosion of an elastic body by winding a rustproof tape on the elastic body, and sticking sacrifice positive electrode plates to a valve element when a keyway provided on a cover body is closed by the valve element energized by a weight and the elastic body such as a spring. CONSTITUTION:Sacrifice positive electrode plates 10a, 10b are stuck 7 on both sides of the weight 1c of a valve element 1 with a conducting adhesive, and a rustproof tape is wound at the apex of an elastic body 3. When a cover for an underground buried object is buried in the horizontal ground G, a valve cover 1a is inserted into the keyway 2 of a cover body (a) by the weight 1c.

Abstract: PURPOSE:To interactively input the starting point and the direction for generation of a path on a screen where a curved surface is displayed by calculating the coordinate value on the screen for the corner points of the curved surface with input of a point which decides the path generation start point and comparing the coordinate value with the deciding point to automatically decide the path generation start point. CONSTITUTION:A curved surface to which a path is generated is displayed on a display device 3 under the control of a central arithmetic part 11 of a CPU 1. The coordinate values Pa-Pd are obtained by a corner coordinate calculating part 12 in response to the corner points (a)-(d) respectively and stored in a memory 4 as data. Then a deciding point Ps for the path generation start point is inputted to an optional position of the display screen of the device 3 by an input device 2. A nearest corner point calculating part 13 obtains the distances PsPa, PsPb, PsPc and PsPd between the point Ps and the values Pa-Pd respectively. Then the part 13 calculates the minimum value among those distances. Then the corner point corresponding to the minimum distance value is defined as the path generation start point (a).

Title: Hetero bipolar transistor
Inventor: TERAZONO SHINICHI
IPC: H01L29/73
Filed: 1990-08-17
Abstract: PURPOSE:To improve controllability of surface exposing of a base layer and to enhance performance by forming a base layer made of InAlGaAs formed on a collector layer made of GaAs, a graded layer made of AlGaAs on the base layer, and an emitter layer. CONSTITUTION:If p-type InAlGaAs is used as a base layer 3, In exists only in the layer 3. Thus, for example, if dry etching represented, for example, by ECR, etc., is used, the etching is stopped when light irradiation of the In is detected together with plasma light irradiation analysis to detect the end of etching state, and hence the surface exposing of the layer 3 is facilitated. Since the controllability of surface exposing of the layer 3 is improved, the layer 3 can be reduced in thickness, and performance of an element can be enhanced. Further, since the In is used as part of main constituents, the layer 3 can be narrowed to enhance performance of the element.
