Title: Method for rolling fe-al-cr series alloy steel
Inventor: OTSUKA HIROAKI
IPC: C21D8/02
Filed: 1989-05-29
Abstract: PURPOSE:To stably roll Fe-Al-Cr series alloy steel and to surely and efficiently manufacture a steel strip by cold-rolling at the specific draft after rapidly cooling from the specific temp. range just after hot-rolling a steel slab or steel material. CONSTITUTION:The cast or ingot-making steel slab or steel material is heated and the Fe-Al-Cr series alloy steel plate is obtd. through the hot-rolling and the cold-rolling. In the above rolling method, just after completing the hot- rolling, and if necessary, after annealing the steel plate, the steel plate is rapidly cooled at <=100 deg.C from the temp. range of 600-950 deg.C of the steel plate temp. After that, a cold-rolling is executed to the steel plate at >=50% draft. Particularly, in the case of manufacturing the thin steel strip, the above cold-rolling is preferably executed two or more times containing intermediate annealing. Further, at this time, in the hot-rolling process, it is desirable to execute a rapid cooling treatment from the temp. range of 600-950 deg.C. By this method, the cold rolling is easily and stably executed to manufacture of the steel strip from the Fe-Al-Cr series alloy steel.

Title: Slant incident interferometer device
Inventor: SUZUKI MASANE
IPC: G01B11/24
Filed: 1987-05-29
Abstract: PURPOSE:To measure the irregularities of a surface to be checked accurately with interference fringes, by providing image forming lenses on a light path between a second diffraction grating and a hologram screen, and providing the image forming relation of a equal multiplication. CONSTITUTION:Laser light from a laser oscillator 1 is inputted into a first diffraction grating 4 through a diverging lens 2 and collimator lenses 3. A body under test is mounted on a mounting stage 5 and the flatness of the surface to be checked is checked. The light, which is inputted on the surface to be checked of the body under test and reflected, is made to interfere in a second diffraction grating 6. The luminous flux through the second diffraction grating 6 undergoes equimultiple image forming action through a lens system comprising image forming lenses 20 and 22. The diffracted light from the peripheral part of the surface to be checked is condensed at a point corresponding to a hologram screen 7. Therefore, the roundness at the peripheral part of the interference fringes is eliminated. Mutually parallel interference fringes are formed. Even if diffraction occurs at the peripheral part of the surface to be checked, the effect is not received, and the flatness of the surface is accurately checked.

Abstract: PURPOSE:To prevent a cable from being brought into contact with a disk so as to secure normal rotation of the disk, by providing a hindering member which is engaged with a contacting member at the location where a connecting member hinders the contact with the disk when a pickup reproduces the opposite surface and the surface facing a signal processing section, in the vicinity of the disk. CONSTITUTION:The supporting base 6 and flexible feed cable 104 of a pickup supporting member drive a feed motor 5 from the innermost periphery of a disk 9 and the base 6 makes low-speed scanning on the tips of supporting blocks 17 and 18 in the direction of the arrow so that a pickup 4 can scan the lower surface of the disk 9. At the time of scanning, a bent section 104a is produced in the cable 104 because the cable 104 is bent from a state where it is stretched from a lower chassis 49b and the bent section 104a becomes greater as the base 6 advances toward the outside. When scanning of the lower surface of the disk 9 is completed, the motor 5 is driven at a high speed and the coupling sections 17b and 18b of the base are brought upward. Therefore, the cable 104 is bent to an S-shape and moves along a vertical wall 106.
