Title: Exposure aligner
Inventor: KONUKI HIDEO
IPC: H01L21/027
Filed: 1990-01-17
Abstract: PURPOSE:To realize the short time exposure of a pattern whose line width is 0.4mum or less, by constituting an aligner by using a spiral orbit type undulator inserted into an electronic storage ring, and an exposing chamber provided with a reflection optical system which performs demagnification projection applying the undulator radiation generated from the undulator to a light source. CONSTITUTION:The title aligner is constituted of the following; a spiral orbit type undulator 10 inserted into an electronic storage ring 11, and an exposing chamber provided with a reflection optical system which performs demagnification projection applying the undulator radiation generated from said undulator 20 to a light source. The undulator radiation 20 is projected on a wafer 25 by a Schwarzschild's reflecting mirror 24, after being vertically reflected by a reflecting mirror 21 and passing a reticle 22. A pattern on the reticle 22 is reduced to be about 1/4 and forms an image on the wafer 25. Thereby an aligner capable of the short time exposure of a pattern whose line width is 0.4mum or less can be obtained.

Title: Manufacture of thick steel plate
Inventor: MABUCHI HIDESATO
IPC: B21B1/22
Filed: 1979-01-26
Abstract: PURPOSE: To pressure weld the micropores of cast billet in order to prevent the hydrogen defect, by limiting the shape ratio and the hydrogen content of steel at rolling the billet into the thick plate of 38mm or larger thickness.  
     CONSTITUTION: At rolling the cast billet into the thick plate of 38mm or larger thickness, the value of shape ratio α (length of contact arc/ average thickness) for the rolling condition calculated from the formula I is secured at least once till the final rolling pass, and the hot rolling is carried out. Hereupon, the hydrogen content Hc of the steel at the middle of thickness is restricted to the value obtained from the formula II. The reason of limiting the thickness, shape ratio, and hydrogen content of steel, is because the micropore of cast billet can not be pressure welded by the ordinary rolling, if the thickness is larger than the limited value. And the shape ratio is represented by the ratio given by the formula III (L is the length of contact arc between the rolled material and reducing roll, and Hm is the average thickness). Accordingly, at the initial stage of the rolling work, the average thickness is so large as it requires a large mill capacity and a large roll diameter, hence, the shape ratio must be secured at the limited value. Meanwhile, the hydrogen content of steel must be limited because the microporous hydrogen enrichment due to the hydrogen sensitivity, residual stress, etc., becomes the function of the yield stress.

Filed: 1978-01-27
Abstract: PURPOSE: To surely fix the watch glass of extra thin type by powerfully compressing a cynthetic resin ring between the same and the V-groove of a glass fixing member thereby letting part thereof protrude.  
     CONSTITUTION: A V-groove 11, collar part 12, glass rest face 13 and a taper face 14 for guiding glass 2 are formed on the inside peripheral surface of a bezel 1 and a guide taper face 22 is formed on the outside peripheral surface of the glass 2 and a taper face 32 to a synthetic resin ring 3. Then, if the glass 2 is forced down after the synthetic resin ring 3 has been disposed in the V-groove 11, the glass 2 is guided by the collar part 12 and is forced from the correct position, whereby the inside peripheral surface 31 of the synthetic resin ring 3 is evenly pressed and the synthetic resin ring 3 is powerfully compressed within the space formed by the V-groove 11, the outside diameter face 21 of the glass 2 and the guide taper face 22. Because of its plastic characteristics, the ring infiltrate fully in the surface in the space thereby retaining the waterproofness among members and the fixing power of the glass 2. In addition, part thereof is forced out through the clearance C to form an extruded part 34, which in turn forces the top taper face 25 of the glass 2 downward.
