Title: Vapor growth device
Inventor: SUZUKI JIYUNICHI
IPC: C23C16/46
Filed: 1982-04-21
Abstract: PURPOSE:To make the size of a vapor growth device larger easily by such an arrangement wherein a heating plate structure is composed of a heating plate having a surface on which a semiconductor substrate is to be mounted and another heating plate which is arranged to oppose to the side opposite to said mounting surface of said heating plate, and a heating means which doesn't cause rising-up is formed by using said heating plate structure. CONSTITUTION:In a heating plate structure, 2 circular heating plates 8, 8' of which at least one side has relatively coarse surface, and center holes and outer circumference substantially coincide are used being laid over on another so that their coarse sides are brought to contact each other. By this method, contact resistance between the overlapped upper and lower heating plate is relatively large, and an eddy current generated in the heating plate closer to the lower heating coil hardly flows to the upper heating plate, and the generation of said floating force is almost determined by only the lower heating plate. Further as preferable conditions, a thin layer of which thermal conductivity is not so high is formed between the upper and lower heating plates due to their coarse sides, therefore it cannot be said that thermally they are closely contacted together, and Joule heat generated in the lower plate doesn't propagate to the upper heating plate quickly and unevenness of temperature are hard to be generated, since the upper heating plate is good in thermal conductivity, comparing with quartz. As a heating plate structure, a graphite carbon plate of which surface is coated with silicon carbide is preferable.

Title: Photography system equipped with optical low-pass filter
Inventor: SUGAWARA SABURO
IPC: G02B27/46
Filed: 1991-03-29
Abstract: PURPOSE:To prevent the low-pass effect from decreasing even if a stop aperture interrupts two cycles of a phase grating by positioning an optical low-pass filter at a recessed part formed of a prism body where there is the center of the stop aperture and an adjacent prism body. CONSTITUTION:The phase grating is formed by arranging many trapezoidally sectioned prism bodies at a pitch P and an optical low-pass filter 1 is so arranged that adjacent stop aperture centers C1 are in the adjacent recessed areas of two specific prism bodies. That is, while the stop has a large aperture, diffraction due to a wave optical phenomenon is caused between phase gratings and the low-pass effect is obtained. When the stop is reduced, the low-pass effect by the diffraction decreases, but geometric optical refraction effect by adjacent recessed parts becomes dominant instead and a spot image is separated into two to maintain the desired low-pass effect.
