Abstract: PURPOSE:To obtain a high erasing rate and to achieve the erasure with low heat loss as well by irradiating an irradiation surface with a recording beam followed by a beam capable of making the surface temp. at a crystal nucleus forming temp. which is less than a crystallization temp. CONSTITUTION:A track 1 is irradiated by an erasing light beam a1 precedent to the recording light beam a2, and the recording surface is brought under the crystallization temp. by this irradiation, and is afterward cooled by moving the irradiating position to become under the crystallization state prior to recording like an irradiation part d1 so as to carry out the erasure.

The track 1 finished with the recording is irradiated continuously by a crystal nucleus forming light beam a3 arranged further to follow the above beam. As a result, the recording disk is raised in its temp. slightly below the crystallization temp., and the crystal nuclei are formed like an irradiation part d3.

Title: Pattern generator
Inventor: HOSAKA SUMIO
IPC: H01L21/30
Filed: 1980-12-17
Abstract: PURPOSE: To etch a highly fine pattern with a high speed by a method wherein photoresist is directly patterned by laser processing technology.  
     CONSTITUTION: A laser beam 24 from a processing laser source 22 is introduced into a polarizer 25 through an optical modulator 23 and is polarized to X- and Y-direction for at least one axis. After the polarization the laser beam 24 is bent by a reflecting mirror 26 and is focused on a film 29 to be patterned on a specimen 28 by a focusing lens 27 and direct processing is performed. During such direct processing a focus depth is small because the laser beam 24 is  squeezed to a very small spot diameter. So the focusing position is kept constant by a Z-axis shifting mechanism of a shifting stand in vacuum. With above method, as the laser beam has a high resolving power and can be polarized with a high speed, a highly fine pattern can be obtained and because of the direct laser processing, conventional process such as resist process is eliminated, so that manufacturing time can be reduced.

Title: Automatic focusing device for vertical illumination type microscope
Inventor: YOSHIKAWA KUNIYUKI
IPC: G02B7/34
Filed: 1989-07-10
Abstract: PURPOSE:To enable high-accuracy focus detection even to an object surface which is not uniform in reflection factor by bisecting focus detection light and measuring only one-side outputs in the same direction of the center of gravity of the outputs of a light receiving00 device corresponding to the split focus detection light beams one by one. CONSTITUTION:When the light gravity center position of two light receiving images on a light position detector 35 in a focus state is regarded as a standard, the light receiving images move in the reverse directions on the light position detector 35 responding with the quantity of deviation of a body in the optical-axis direction according to whether the images are in a front or rear focus state, so the quantity of defocusing is reflected on the equal-directional integral vales of the integral values of the light receiving images at the reference position. Here, an arithmetic means 36 calculates a focusing signal according to the integration values, so a driving control means 37 performs driving control over the gap between the object surface 24 and an objective 23 so that an accurate focusing position is obtained irrelevantly to variance in the reflection factor of the object surface. Consequently, the invariably accurate focusing position is obtained as to the object surface 24 which is not uniform in reflection factor.

Abstract: PROBLEM TO BE SOLVED: To provide a slurry supply structure for a wire saw in which a wire can cut a workpiece uniformly on a new wire supply side and a new wire outlet side. SOLUTION: Slurry supply nozzles 18 are arranged more on the new wire outlet side B than on the new wire inlet side A to supply more slurry to wire rows 16B in the new wire outlet side B than to wire rows 16A on the new wire inlet side A.
