Title: Rolling mill of metallic plate and rolling method
Inventor: KIJIMA HIDEO
IPC: B21B27/00
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce rolling cost and to obtain a rolling mill for producing a metallic plate excellent in surface gloss by using a cemented carbide roll having a Young's modulus of a specified value or more for either one of a pair of upper/lower work rolls for rolling a metallic plate and a steel forged roll for the other. SOLUTION: A WC cemented carbide roll having a Young's modulus of >=35000 kg/mm2 is used for one of work rolls. In the case of the cemented carbide roll of a compound roll, a thickness of the cemented carbide is preferably >=3% of a roll radius so that a surface gloss difference between a surface gloss layer and an integrated roll is <=10%. The reason, why the surface gloss to be rolled with the cemented carbide roll is increased, is that a flattening quantity of the cemented carbide roll is smaller than a flattening quantity of a forged steel roll, a bite-in angle αL of the cemented carbide roll is larger than a bite-in angle αU of the forged steel roll and then an oil film in roll bite-in is thinned, accordingly, an oil pit defect is reduced.

Title: Solid-state laser equipment
Inventor: YAMADA AKITAKA
IPC: H01S3/117
Filed: 1989-07-31
Abstract: PURPOSE:To miniaturize an optical resonator and unnecessitate the optical axis adjustment, by arranging a laser gain part and a Q-switching part in a body in solid-state laser medium, and installing a function curved surface minimizing the laser medium dimension on a laser optical axis. CONSTITUTION:When a semiconductor laser 15 is operated and laser light L1 is made to enter from a first coating 14 of solid-state laser medium 12, a part A adjacent to the coating 14 of the medium 12 is excited. YAG laser light L2 oscillates between coatings 14, 16, and emitted from the coating 16. When ultrasonic signal is turned ON, and ultrasonic wave U is generated in the medium 12 by an ultrasonic wave transducer 19, the laser light L2 is diffracted and the oscillation is interrupted. When the ultrasonic wave signal is turned OFF, the laser light L2 oscillates. By a pair of function curved surfaces 17 in the vicinity of an optical axis, the thickness of the medium 12 is reduced to about 1/5. By a convex surface 18, the width is reduced to about 1/3. Hence the intensity of the ultrasonic wave is amplified 15 times, and the diffraction efficiency is increased 4 times.
