Title: Rotary saw
Inventor: KOSUGE KENZO
IPC: B23D61/04
Filed: 1994-11-23
Abstract: PURPOSE: To provide a rotary saw that can positively prevent the generation of burrs and a phenomenon of edge deviation during cutting work. CONSTITUTION: An inclined edge 5 with the flat face 8 and the inclined face 9 formed at the tip part, an inclined edge 6 with the flat face 10 and the inclined face 11, formed at the tip part, and a flat edge 7 with the flat face 12 formed at the tip part are fitted in regular succession to each edge body 4 formed every constant pitch at the peripheral edge of a base metal 2. The inclined edges 5, 6 are opposedly positioned so that the cutting loci of the inclined faces 9, 11 are partially overlapped, and the flat edge 7 is positioned at the cutting locus center between the inclined edges 5, 6. A cut part in cut material can be partially cut at one side part thereof by the inclined edge 5, at the other side part by the inclined edge 6, and at the center part by the flat edge 7 in regular succession.  Stress generated by pressing force and cutting force at the cutting time therefore acts upon each cut face in small degree, so that the generation of burrs and a phenomenon of edge deviation can be positively prevented.

Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To perform optimum laser annealing and obtain a highly reliable semiconductor film with less nonuniformity by irradiating the film with pulsed laser beams through an insulating transparent board. SOLUTION: Laser beams projected into an optical system pass through a cylindrical concave lens A, a cylindrical convex lens B, a fly eye lens C in the horizontal direction and a fly eye lens D in the vertical direction. The laser beam distribution changes to rectangular distribution from the previous Gaussian distribution after passing through the fly eye lenses C and D. Furthermore, after passing through the cylindrical convex lenses E and F, the laser beams are focused by a cylindrical lens H through a mirror G. Then, the beams are applied on a sample. The beams are processed into fine and long beams to improve processability.

Title: Method for automatically aligning laser oscillation
Inventor: KOJIMA SATOSHI
IPC: H01S3/086
Filed: 1990-11-20
Abstract: PURPOSE:To automatically set the optimum mirror angle in a short time by performing prescribed arithmetic operations by using the difference between the output of a reference point and the outputs of surrounding points of the reference point. CONSTITUTION:The maximum output point is found from the output distribution of a laser against the mirror angle. The output of a certain point and the outputs of its surrounding four points are measured. The measurement is performed by controlling the mirror angle in such a way that the output f (x, y) of the current reference point (x, y) is first found and the outputs (f) of the surrounding points are found in accordance with a control algorithm. After obtaining the outputs, the differences between the output of the reference point and outputs of the surrounding points are found and linear differentiation is made on the differences and differential values dxf, dxr, dyf, dyr are found. Then measuring points are decided from these data. The optimum mirror angle is found by repeating such arithmetic operations and converging the matching. When such constitution is used, accurate matching can be automatically obtained in a short time.

Title: High-temperature superconductive permanent magnet
Inventor: YOKOYAMA SHOICHI
IPC: H01F7/02
Filed: 1989-12-04
Abstract: PURPOSE:To obtain an arbitrary magnetic-field distribution by one exciting operation without the requirement for a permanent current switch by cooling a high-temperature superconductive permanent magnet, thereafter applying an external magnetic field which is twice or more the critical magnetic field, and exciting the magnet under the critical state. CONSTITUTION:A high-temperature superconductive permanent magnet 1 is molded as a unitary body or formed in an arbitrary shape in a divided type. An external magnetic field (b) which is twice a critical magnetic field is applied on the permanent magnet after the high-temperature superconductive permanent magnet 1 is cooled. Thus, the magnet is excited in the critical state. For example, the superconductive magnet 1 comprising an oxide superconductor is cooled to the critical temperature or lower. Thereafter, an external magnetic field (b) from an exciting magnet 4 is increased to a value higher than J. Then, the magnetic flux starts intrusion into the inside of the superconductive magnet 1 at the critical magnetic field Be1:K. Then, the magnetic field is further increased. The entire superconductor becomes the critical state at Be2:L which is about twice the Be1. Then a uniform superconducting current flows. Even if the external magnetic field is decreased to zero from this state, the magnetic flux intruded into the inside of the superconductive magnet 1 is hardly decreased but confined (N).
