Title: Method for preventing discoloration of steel strip in electrolytic cleaning line
Inventor: KOBAYASHI YOSHIKI
IPC: C25F1/00
Filed: 1980-12-26
Abstract: PURPOSE: To prevent the discoloration of a steel strip owing to formation of rust by pulling up the steel strip in a hot water vessel from the liquid surface and improving ventilation thereby evaporating the moisture stuck thereof quickly during handling time.  
     CONSTITUTION: During handling time, immersion rolls 16 are pulled up to the positions 16' above the water surface, by which the steel strip 15 immersed in the hot water is pulled up to the position 15' above the water surface. At the same instant of these operations, an air releasing blower 18 operates to suck the steam in the vessel, thereby evaporating the moisture stuck on the surfaces of the steel strip quickly. In this way, the formation of rust of the steel strip is prevented; hence, the discoloration thereof is prevented.

Filed: 1982-10-19
Abstract: PURPOSE:To prepare a crystal with a low-power laser beam in high efficiency, by covering the raw material of crystal with an optically transparent covering material in a spherical form, enclosing the sphere with concave mirrors provided with windows at definite intervals, and heating and melting the crystal raw material with laser beams introduced through the windows. CONSTITUTION:The raw material of crystal 1 is covered with a covering material 2 made of a transparent substance such as glass in the form of a sphere, which is enclosed with concave mirrors 6 provided with windows at definite intervals. The material 1 is heated and molten by introducing laser beams 3 through the windows 5. The radiant heat emitting from the sphere in the form of heat ray 4 by the heating of the material 1 is mostly reflected by the concave mirror 6 and focused again to the material 1. Accordingly, the radiation loss can be remarkably suppressed, and the power of the laser beam 3 can be considerably lowered by this method. After melting, the radiation of the light 3 is stopped, and the material 1 is cooled to obtain a crystal such as diamond crystal.
