Inventor: YAMAZAKI HISAO
IPC: B22D11/12
Filed: 1987-12-21
Abstract: PURPOSE:To obtain a round-shape billet having only a little internal defect with continuous casting by solidifying molten steel in the hypo-peritectic range while pouring into polygonal mold and successively, executing rolling-reduction 1 under the specific condition with the rolling-reduction of arc-like metallic mold in the specific range of the solid phase ratio in axial center part in the cast billet. CONSTITUTION:The molten steel in the hypo-peritectic range of 0.10-0.18wt.% C is solidified while pouring in the polygonal mold 1 having more than square shape, and the rolling reduction is continuously executed with the arc-like metallic mold 3, to reduce center segregation and center porosity while forming into the round cross section. In this case, the rolling reduction is executed to the polygonal cast billet running out from the mold 1 in the range of 0.5-0.9 the solid phase ratio fs in the axial center part of the cast billet with the rollingreduction device arranging the arc-like metallic mold 3 at >=0.6 of the rolling reduction rate mm/non-solidified rate mm, to make the round-shape billet. Burr developed after rolling reduction is removed with a burner 5.

Title: Differential amplifier
Inventor: YAMAZAKI KOICHI
IPC: H01L29/735
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To improve input offset voltage, also to avoid the increase of a chip size, and to prevent an increase in costs by replacing an element that affects the input offset voltage of a CMOS type differential amplifier by a bipolar element in a normal CMOS process. SOLUTION: An input element 21 on the side of an inverted input of a differential amplification stage 102 of a CMOS type differential amplifier and an input, element 22 on the side of a non-inverted input are replaced by a PNP transistor rather than instead of a P-channel MOSFET. Input offset of the CMOS type differential amplifier is affected greatly by the elements 21 and 22, and the input offset is improved by replacing the elements 21 and 22 with a bipolar transistor. Consequently, it is possible to provide a CMOS process type differential amplifier which is inexpensive, is mounted on a small device and has small input offset voltage without accompanying the addition of a trimming process and the increase in chip size.

Title: Method and device for magnification correcting of x-ray aligner
Inventor: FUJII KIYOSHI
IPC: H01L21/027
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To make magnification of an X-ray aligner correctable in a short time without applying heat nor external force to an X-ray mask at a time of transferring a large-area fine circuit pattern to a work, such as the semiconductor substrate, etc., by correcting the magnification at the transferring time by deforming an X-ray mirror. SOLUTION: A mirror curvature controller 3 is set up on the back 2c of a cylindrical vibrating mirror 2 having a curvature in the horizontal direction. The controller 3 changes the curvature of the mirror 2 by deforming a piezoelectric element 31 at the center on the back 2c of the mirror 2c, by impressing a necessary voltage upon the element 31 from a power source 32. When the curvature of the mirror 2 is changed, angle of divergence of X-rays in reflected synchrotron radiation light in the horizontal direction changes. When the angle of divergence changes, the direction of X-rays made incident to an X-ray mask changes and the transferring position of a mask pattern changes. Since no heat nor external force is applied to the X-ray mask, the mask has no danger of breakage.
