Filed: 1989-04-25
Abstract: PURPOSE:To prevent the quantity of irradiation light from going to unbalance by increasing or decreasing the light irradiated area of at least one of plural provided filter areas almost continuously in the moving direction of an optical path stop down plate. CONSTITUTION:The optical path down stop plate 5 is provided between a light source 1 and a condenser lens 2 and this plate 5 is displaced at right angles to the optical path to stop down the optical path. An R filter area 10R and a G filter area 10G are so formed that the arc angles of the outer peripheral edge parts are small, and the circumferential length of the light irradiating area decreases continuously from the inner peripheral side of a color filter 10 to the outer peripheral side on the whole. Therefore, when the quantity of irradiation light is adjusted by displacing the plate 5, its stop-down quantity and the attenuation rates of respective wavelength range light beams of the respective filter areas 10R, 10G, and 10B of R, G, and B can be corrected. Consequently, an image displayed on a monitor screen is prevented from having color slipping on the whole and the color reproducibility of the image comes to extremely excellent.

Abstract: PROBLEM TO BE SOLVED: To enable a hydrogen-permeable membrane to display its function sufficiently by first previously welding the superposed parts of the hydrogen-permeable membranes, then registering their mutual positions and sealing the holes of the defectively welded spots after securing the joining properties to some extent. SOLUTION: Stacked foils 2 are mutually seam-welded 4 beforehand or welded by any other means and their positions are registered to secure their joining properties to some extent. Next, holes in the defectively welded spots are sealed. The sealing process is performed by making a paste of a material for the sealing and applying the paste to a part 5 along the seam of a welded line, and further, thermally treating the seam at a temperature complying with the type of a material used. The porous support 1 to be used is, for example, of a stainless steel porous material perforated by etching, a porous material obtained by molding stainless steel powder and sintering it, or a ceramic porous material such as an oxide of alumina or the like, a nitride of silicon or a carbide of silicon or the like.  Since the part where foils 2 are superposed on each other is in a sufficiently airtight sealing state, no leakage of a gas containing hydrogen occurs and, therefore, the required function of the membrane is secured.

Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a single crystal low in O2 concentration by arranging a specific controlling plate at a fixed position in pulling up a silicon single crystal from a silicon melt in a quartz crucible by a CZ method. SOLUTION: A convection controlling plate 7 having approximately the same diameter as that of a single crystal C, preferably composed of quartz as a material, is restrictively installed at a position right below the single crystal C in a melt B. Consequently, the convection of the melt B in a crucible A is basically suppressed, supply of O2 to a solid-liquid interface is limited to reduce O2 concentration of the single crystal C. Optionally, a distance from the single crystal C to the convection controlling plate 7 is changed while the single crystal is pulled up. Namely, the uniformizing of O2 concentration distribution in the whole zone in the direction of a pulling up shaft is made possible.  Preferably, the diameter of the convection control plate 7 is made larger than that of a collection zone of a wafer device cut out from the silicon single crystal C and is made <=1.5 the diameter of the silicon single crystal C. Namely rise in O2 concentration is avoided and controllability of O2 concentration is raised.
