Title: Index bestowing method for three-dimensional picture
Inventor: HORIKOSHI TSUTOMU
IPC: G06T7/20
Filed: 1988-10-11
Abstract: PURPOSE:To describe the three-dimensional shape or the size, etc., of three- dimensional picture data objectively as physical quantity by bestowing an index upon the three-dimensional picture data by using three-dimensional shape expression by a function. CONSTITUTION:It is assumed that a glass is chosen as a three-dimensional structure. In a collating device 12, the fundamental shape of a superquadratic function is called out from a superquadratic function converting device 13 through a line (e), and the three-dimensional data of the glass and the superquadratic function are matched with each other. Then, a parameter related to the shape description of the superquadratic function at the point of time when the shape of the superquadratic function is decided to become the same as the approximate shape of the glass is extracted. A ink is formed through the line (f) between the three-dimensional picture data inputted to a three- dimensional picture data storing part 15 through the line (a) and the index stored in an index storing part 16, and they are stored as the three-dimensional picture data to which the index is given in a three-dimensional picture data base 14. Further, for other object of a three-dimensional picture, the same operation is repeated.

Filed: 1990-09-25
Abstract: PURPOSE:To reflect incident light effectively without machining the surface of substrate material itself by interposing an irregular reflection layer between a substrate and a high reflection conductive layer while giving interface stabilization to the irregular reflection layer so as to be brought into contact with a conductive film.

Filed: 1984-12-04
Abstract: PURPOSE:To enable stabilized die bonding and wire bonding by a method wherein heater brock wire a groove, whose form goes along to an internal pattern containing an inner lead as well as a semmiconductor element mounting section of a leadframe, is used. CONSTITUTION:Constitution of a heater brock possesses a groove 8 whose form goes along to an internal pattern containing an inner lead as well as a semiconductor element mounting section. Accordingly, deformation of a leadframe is revised at die bonding process, then dispersion of the leadframe position is reduced and also discrepancy of semiconductor element mounting position is reduced too by means that a leadframe-tab section is sent always to the same position on the heat brock. Additionally, adhesion to the semiconductor element-tab section comes to be performed stably by means that the leadframe is clamped by a work pressure and heater brock. Since the heater brock contacts with the deversity section of the leadframe and also the lead section introduced to the outside of resin sealed area does not come to contact therewith, stick of sealing burr can be reduced and coating process is performed.

Title: Containment vent equipment
Inventor: TATE HITOSHI
IPC: G21C9/004
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To enable reduction in the quantity of radioactivity discharge to the environment by remotely operating the isolation valve of connection pipe connecting inert gas system piping and main steam piping and holding radioactive rare gas in a rare gas holdup tower. SOLUTION: A connection pipe isolation plate 62 has a function of loosing isolation state when specific pressure is reached. Due to opening of a connection pipe isolation valve 61 and pressure rising in the containment 1, the isolation function of the connection pipe isolation plate 62 is lost and the gas in an inert gas system pipe 31 flows out to a main steam pipe 11 side. Here, this connection pipe employs the shortest route by surveying the position relation between the main steam pipe 11 and the inert gas system pipe 31. Thereby, radioactive rare gas in the atmosphere gas stagnates in active carbon in an active carbon type rare gas holdup tower 47 of a radioactive gas waste processing equipment provided in an existing reactor power station and reduces so that its radioactivity level. can be reduced.
