Abstract: PURPOSE: To easily produce a high quality single crystal of a large diameter at a low cost by sliding the center of a seed crystal from the center of a raw material rod and turning the seed crystal side in production of a single crystal by a floating zone method using infrared rays.  
     CONSTITUTION: In production of a single crystal by a floating zone method by which infrared rays from a halogen lamp, a xenon lamp or the like are concentrated with a spheroidal mirror to heat melt a raw material rod followed by crystallization, center line 10 of seed crystal 9 is set at the outside of center line 8 of raw material rod 7, crystal 9 is mounted on support stand 11, and the turning center of stand 11 is allowed to coincide with line 8 to grow a single crystal. Thus, crystal 9 turns round line 8, and infrared rays can reach the bottom center of rod 7 and the central part of melting zone 12. Accordingly, a single crystal of a large diameter can be grown, and segregation of impurities at the central part is prevented.

Title: Method and device for detecting glosiness
Inventor: SUZUKI SHIYOUICHI
IPC: G01N21/57
Filed: 1982-07-23
Abstract: PURPOSE:To detect the change in glosiness in an early stage, by making a light beam including the wavelength region of 400nm to radiate on the painted surface of a body to be measured, receiving the reflected light through filters, which pass only the wavelength region of 400nm, and detecting the glosiness based on the intensity of the light beam. CONSTITUTION:A light beam including the wavelength region of 400nm from a light source part 1 is made to radiate on the painted surface S of a body to be measured at a required incident angle through a slit 3, a lens 4, and a variable stop 5. The reflected light is detected by a light receiving device 10 through a variable stop 6, filters 71 and 72, which pass only the light beam having the wavelength of 400nm, a lens 8, and a slit 9. The result is amplified by an amplifier 11 and displayed on a display meter 12. The light beam, whose wavelength is in the vicinity of 400nm is sharply diffused in correspondence with the state of the painted surface S. If there is unevenness on the painted surface, the intensity of the reflected light becomes conspicuously weak. In this way, the change in the glosiness can be detected in the early stage.
