Publication number: 20060033050Abstract: In the case of drawing an oblique figure pattern, when drawing an oblique figure by using a slender rectangular beam, a problem occurs that edge roughness occurs at an oblique-side portion to deteriorate the drawing accuracy. The present invention solves the above problem and provides an electron-beam drawing apparatus and an electron-beam drawing method capable of accurately drawing even an oblique figure. A first rectangular aperture and a second parallelogrammatic aperture are used and a variable parallelogrammatic electron beam formed by two apertures is used to draw a desired pattern on the surface of a sample. Moreover, oblique-side-portion-contour decomposition means is used to draw an oblique-side portion by a variable parallelogram and the inside of an oblique side by a triangle and a quadrangle (rectangle).Type: ApplicationFiled: October 18, 2005Publication date: February 16, 2006Inventors: Kimiaki Ando, Haruo Yoda, Rikio Tomiyoshi, Masamichi Kawano

Patent number: 6478900Abstract: An improved method of forging a precipitation hardening type stainless steel. The method comprises the steps of soaking the precipitation hardening type stainless steel at a temperature of austenitizing range, cooling the steel to a temperature in the range of 200-700° C., preferably 400-600° C., and subjecting the steel to forging at the temperature in this range. Conventional lubricants and die cooling oils can be used without being deteriorated due to high temperature. It is preferable to forcibly cool the soaked steel to adjust the temperature of the steel at which it is forged. The forged steel is then age hardened to exhibit inherent hardness.Type: GrantFiled: July 1, 1996Date of Patent: November 12, 2002Assignee: Diado Tokushuko Kabushiki KaishaInventors: Sachihiro Isogawa, Masamichi Kawano, Katsuyoshi Sakoda
