Title: Aberration coefficient measuring method of reduced projecting aligner
Inventor: UCHIDA NOBORU
IPC: H01L21/027
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To easily measure the aberration coefficient of a stepper, by a method wherein a plurality of pitches are formed at shot center, and the spherical aberration coefficient for the whole area of shot is measured by the center value in the range of formation of each pattern. SOLUTION: In an optical system having a stepper, a line and space pattern is formed by the three-luminous flux coupling which is symmetrical to optical axis under the illumination approximate to the coherent having the abarration coefficient σ of a stepper of about 0.1 or lower. The line and space pattern is formed at the center of shot by changing focus in several kinds of pitches and shots in the direction of radiation and in the direction which orthogonally intersects with it. The center value of the best focus range is computed for each pattern formed, and if there is an aberation in the center value of the focus range, pattern pitches are different. Accordingly, an aberation can be computed.

Abstract: PURPOSE:To easily manufacture a metallic multilayer tube having an excellent metallic joining by activating the mutual contact surfaces of metallic pipes in advance by grinding, etc., combining them concentrically, and expanding the pipe diameters while ultrasonic oscillation is applied in their axial direction. CONSTITUTION:A metallic tube 2 whose outside is ground by a grinding stone, etc., is inserted into a metallic tube 1 whose inside is polished by a steel brush, etc., and the outside of the metallic tube 1 is restrained by a die 5. Then, inner pressure is applied by a pump 3 to the metallic tube 2 to expand the pipe, the metallic tubes 1, 2 are closely brought into contact with each other and axial ultrasonic oscillation is given by an ultrasonic oscillation transmitting device 4 to the metallic pipe 2. At this time, the amplitude of the ultrasonic oscillation transmitted to the metallic pipe 2 is set so that the maximum is given at the contact part with the metallic tube 2 and the difference between the inner diameter of the metallic tube 1 and the outer diameter of the metallic tube 2 before it is expanded is made equal to 0.2-0.5% of the outer diameter of the metallic tube 2. Thus, a metallic multilayer tube having an excellent metallic joining between layers is manufactured easily and at a low cost.

IPC: G11B15/61
Filed: 1985-12-20
Abstract: PURPOSE:To omit an adjusting mechanism for a drawing out post position by winding a tape always around an A/C head by a drawing arm. CONSTITUTION:Immediately after loading a cassette, the drawing out arm 13 is rotated around a supporting point O in the clockwise direction and a tape 14 is drawn out from the 1st position A of the post 12 to the 2nd position B, and when the tape 14 is wound around an A/C head 5 by a prescribed angle, stopped temporarily. At that time, a P5 post 9 draws out the tape 14 almost at a similar timing to form a tape traveling course. Under said state, stop and FF/REW operation are executed. Since the supporting point O of the drawing out arm 13 is formed on the intersection point between a straight line connecting P to G and a straight line dividing the tape winding angle theta of the post 12 into two parts, the ratio of the change of the tape traveling course from the A/C head to the change of the point B in the rotational direction is reduced even if the point B is slightly dispersed by the dispersion of the drawing out arm 13 or force (f) is applied to the drawing out post 12 by tape tention (t).

Title: Method for preparation of catalyst for controlling exhaust gas emission
Inventor: KANAZAWA TAKAAKI
IPC: B01J37/08
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To prepare a catalyst for controlling exhaust gas emission wherein grain growth of a carried noble metal can be suppressed in a case where high temperature of at least 800 deg.C acts for a long time under a lean atmosphere with excess of oxygen. SOLUTION: A carrier on which a noble metal is carried by using a noble metal compound solution is heat-treated at 1,050-1,150 deg.C under a non-oxidative atmosphere. Since the porous carrier is sintered and fine holes are shrunk and the carried fine noble metal particles are closely taken into the porous carrier, the particles are hardly moved. In addition, as the heat treatment is performed under the non-oxidative atmosphere, there is no possibility of generating PtO2, etc., and generating vapor phase movement. In addition, by performing the heat treatment at 1,050-1,150 deg.C, grain growth of the noble metal at heat treatment process can be especially suppressed.

Title: Cut sheet feeder
Inventor: KONISHI HIROSHI
IPC: B41J13/10
Filed: 1988-11-18
Abstract: PURPOSE:To move a hopper roller to a proper position and stabilize feed of a sheet by providing a deflecting means at a sheet guide for generating a predetermined pressure to at the hopper roller. CONSTITUTION:If a set lever 10 is pushed, a movable shaft 7 is moved up along a slit 8a by the deflecting force of a pressure spring 9. As a result, the front part of a cut sheet 1 is pushed up by a pressure sleeve 7a, and the cut sheet 1 is applied to a hopper roller 5. If a sheet guide 2 is moved, the pressure spring 9 moves together, and the deflecting force is applied at the same distance from the end of the cut sheet 1 with the same strength, so diagonal advance is prevented. Since a step is provided between the bottom plate of the sheet guide 2 and a hopper sheet support frame 4, the strength of the cut sheet 1 is increased, and the long sheet 1 can be supported by the relatively short frame 4.
