IPC: G05B19/4097
Filed: 1986-06-06
Abstract: PURPOSE:To omit a process for converting a curved surface to a polyhedron, by calculating an intersecting line by utilizing a surface normal vector which is held by the curved surface itself. CONSTITUTION:A plane is designated, based on three points of a vertical point P2 of a normal vector N1 of a given point P1 to a curved surface SF1, a vertical point P3 of a normal vector N2 of the given point P1 to a curved surfaces SF2, and the given point P1 on a space. An intersection between the curved surface SF1 and and SF2 exists on its plane, and and an intersection position exists in case a position relation of these three points is minimum, therefore, as for the position relation of three points, it is considered that those three points exist on the periphery of a circle C1. The intersection between the curved surface SF1 and SF2 exists at a position in the symmetrical direction of the point P1 against the center of this circle C1. Accordingly, by moving successively an optional given point on a space to a symmetrical position on each periphery, an intersection T1 between the curved surface SF1 and SF2 can be derived, and since the intersecting line between the curved surfaces is a set of the intersection T1, an intersecting line NL can be derived by repeating said processing procedure.

Abstract: PROBLEM TO BE SOLVED: To inexpensively execute a high speed processing by sorting plural polygons where ridge lines cross on one scanning line in the direction of an X-axis on the scanning line with a specified position as a reference and sorting it with the Z-coordinate value as the reference. SOLUTION: When all the polygons are read into the active polygon list 103 of an inner cache memory by a control circuit 102 in picture plotting LSI, active data is transferred to the processing scanning line from the list and an active detection circuit 104 detects the ridge lines crossing the scanning line from top data of the polygon. When a polygon edge detection circuit 105 obtains the coordinate (X value) of a point where the ridge line and the scanning line cross, a scanning line X sorting circuit 107 sorts all the active polygons out the pertinent scanning line by notifying a left edge. Then, edge data are inputted to a scanning line Z sorting circuit 108 in the sorting order and only polygon data whose Z value is the smallest is transferred to a plotting block.

Title: Push-button switch
Inventor: TSUTSUMI JOJI
IPC: H01H13/48
Filed: 1991-05-09
Abstract: PURPOSE:To prevent a variation of the spring property of a leaf spring in a reflow soldering by attaching a heat reflection layer which consists of a metallic film, a metal foil, or the like, to the outer surface of a housing. CONSTITUTION:A heat reflection layer 7 is attached to the outer surface of a cover sheet 6 to close the opening la of a housing 1. And when a reflow soldering is carried out in the mounting process to solder terminals 4 to a printed wiring plate or the like, the infrared rays radiated to the sheet 6 are reflected considerably by the layer 7 which consists of an aluminum membrane. As a result, the amount of the thermal energy fed to a leaf spring 5 through the sheet 6 is reduced extensively, and it is not necessary to consider the variation of the spring property of the spring 5 resulting from a high heating. In other words, since the infrared rays are liable to be reflected by the layer 7 even though the spring 5 set in the housing 1 is liable to receive the feeding of the thermal energy through the opening 1a in a reflow soldering, the spring property of the spring 5 is not changed remarkably by the thermal energy, and a high reliability can be maintained even after the mounting.
