Title: Method and apparatus for precise-polishing semiconductor substrate
Inventor: TAKAHASHI KAZUO
IPC: H01L21/308
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for precise polishing, which can flatten and eliminate a metal film without forming a process degeneration layer on a surface of a metal after polished and causing burying due to damages, minute particles, or the like on the surface of the metal by a method, wherein the metal film is polished by using an etchant in which a chemical action is main in a chemical and mechanical polishing. SOLUTION: In this precise polishing method, a face, having a metal for constituting a semiconductor device in a substrate 1, is pressed with a slight processing pressure with respect to a hard polishing pad 4, and also an etchant 7 is supplied to an abutting face between the face and the polishing pad 4, while a relative movement is given to the face and the polishing pad 4. Due to the heat caused by friction between a projection part of a metal film existing in the face and the polishing pad 4, increase in temperatures is caused locally in the etchant, and the etching rate of the etchant is accelerated, and the projection part of the metal film is selectively etched to flatten, and thereafter it is uniformly etched to remove the metal film.

Title: Pivoting clamp cylinder
Inventor: NODA MITSUO
IPC: B25B5/06
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of inertial force produced by the pivoting of a clamp arm at an unclamping angle position. SOLUTION: A piston rod 40 being clamped advances leftwards. The clamp arm is moved axially from a workpiece clamping condition by engagement of a linear guide groove part 51 with a steel ball 54, and a piston 43 further advances so that the clamp arm is pivoted as it is axially moved from a clamping angle position to the unclamping angle position. At its pivoting end, the piston rod 40 tends to pivot in its pivoting direction because of the inertial force produced by the pivoting of the clamp arm, so the steel ball 54 is guided on an arc by an arcuate movement guiding surface 70a and smoothly shifts to the linear guide groove part 53 at the unclamping angle position. After moving axially, the steel ball stops at the unclamping angle position.  Since the steel ball does not stop within a pivoting guiding groove part 52, the influence of the inertial force produced by the pivotal movement of the clamp arm can be reduced.

Title: Plug for manufacturing hot seamless tube
Inventor: TSUBOUCHI KENJI
IPC: B21B19/04
Filed: 1989-12-25
Abstract: PURPOSE:To prevent the erosion and deformation of plug even when a seamless tube of high-alloy steel or nickel base alloy, etc., is manufactured by forming a covering layer of specified composition on the surface of base material for plug and forming the layer of iron oxide on that covering layer. CONSTITUTION:The covering layer 2b is made of a matrix which consists of iron base alloy in which >=60wt.% iron-component is contained and carbide particles dispersing mixed in the matrix at 20 - 70% by volume. Since the matrix plays the role of binder with which carbide particles are held and also has ductility and toughness compared with the particle of carbide, the generation and extension of crack in a rapidly heating and cooling the plug is prevented. And, it is done in order to allow to form an iron oxide layer 2c with adequate depth on the surface of the covering layer 2b that iron-component in the iron base alloy is taken >=60wt.%. By taking the depth of that iron oxide layer 2c as 30 - 300mum, since the iron oxide layer 2c is formed by oxidizing the iron- component in iron base alloy of the covering layer, it is strongly integrated and isn't simply stripped off and allowed to fall off.

Title: Mounting structure of energy absorbing body whose thickness varies in axial direction
Inventor: SON MINE
IPC: F16F7/12
Filed: 1994-12-26
Abstract: PURPOSE: To provide a mounting structure of an energy absorbing body so that an expected performance of the energy absorbing body may be exhibited and personal safety can be attained. CONSTITUTION: The diameter of an energy absorbing body internal surface 1b becomes smaller as a contact terminal 7 moves downward, but because the contact terminal 7 makes a gradual bending deformation starting from its contact end part 8, it continues a positive contact with the internal surface of an energy absorbing body 1 till it reaches the bottom and the position and the contour of the uncrushed part is maintained and secured. The contact end part 8 makes a linear contact with the internal surface 1b in a thin lip shape before it starts to crush and becomes thicker as it approaches the axis of the energy absorbing body 1 the forming a fixed end 9. When crushing advances, the contact end part 8 makes a bending deformation and shifts from the linear contact to a surface contact and the load point of reaction force received by the contact terminal 7 approaches the fixed end 9 side. Reinforcement of the energy absorbing body 1 in the circumferential direction is realized by the sudden increase of bending rigidity of the contact terminal 7 and the contact end par 8 completely sticking to the internal surface 1b by the deformation reaction.
