Patent number: 7466854Abstract: A pair of edges that are located at ends as viewed in the widthwise direction of a design pattern are recognized. On the basis of the edge direction in which the paired edges are recognized, edge points on the design pattern are detected as sub-pixels. The widthwise dimension of the design pattern is calculated on the basis of the edge points. In addition, the widthwise dimension of a circuit pattern is calculated at the same position as the widthwise dimension of the design pattern. On the basis of the calculated widthwise dimensions, the semiconductor wafer circuit pattern is checked.Type: GrantFiled: August 5, 2005Date of Patent: December 16, 2008Assignee: Kabushiki Kaisha ToshibaInventors: Eiji Sawa, Hiromu Inoue

Patent number: 6435854Abstract: The invention is an apparatus for mixing and injection molding thermosetting polyurethane. The invention involves using a premixer comprising of a series of specially designed premixing chambers, one or more static, rather than dynamic, mixers, and a specially designed dual-path mixer. After the material is mixed it is pumped into an injector, and then deposited into a mold. This entire process is accomplished in an airtight environment. The mold into which the material is pumped is attached to a vacuum that decreases the chances of any air bubbles being trapped inside the mold. New features of the apparatus include a dual-path mixer and a newly designed premixing chamber.Type: GrantFiled: November 12, 1999Date of Patent: August 20, 2002Inventors: Eiji Sawa, Kenichi Kawamoto, Gary L.

Patent number: 5878313Abstract: A developing roller (1) includes a highly conductive shaft (2) and a conductive elastic layer (3). When the developing roller carring a one-component developer thereon comes in contact with or in proximity to an image forming body, the developer is supplied from the roller to a surface of the image forming body, thereby forming a visible image on the image forming body surface. The elastic layer (3) has applied to its surface a resin component having an elongation at rupture of less than 10% as measured according to JIS K7113. The developing roller ensures that images of high quality are reproduced without a drop of image density over a long period of time.Type: GrantFiled: June 26, 1997Date of Patent: March 2, 1999Assignee: Bridgestone CorporationInventors: Koji Takagi, Yoshio Takizawa, Eiji Sawa
