Title: Production of nitride crystal, mixture, liquid phase growth, nitride crystal, nitride crystal powder, and vapor growth
Inventor: SHIBATA MASATOMO
IPC: C30B29/38
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a new method for crystal growth, enabling high-purity group III nitride crystal such as of GaN to be produced easily at low cost, in view of having been difficult to obtain large-sized crystal of such nitrides so far. SOLUTION: This new method comprises the following processes: a group III metallic element is heated and melted, the resulting melt 3 is then injected with a nitrogen atom-contg. gas such as NH3 at a temperature not higher than the melting point of the aimed nitride to produce group III nitride crystallites with high wettability to the melt 3; the resultant mixture of the above crystallites and the melt is used as starting material for the liquid growth process, or group III nitride powder afforded by eliminating the group III metallic element from the above mixture is used as starting material for the vapor growth process;  alternatively, a seed crystal or substrate crystal is immersed in a group III element melt such as of Ga, bubbles of a nitrogen- contg. gas such as NH3 are intermittently contacted with the surface of the above crystal to react the gas with the group III element on the surface to effect the growth of the aimed group III nitride crystal on the surface.

Title: Retaining wall structure
Inventor: KOMATSU TOSHIMITSU
IPC: E02D29/02
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To improve the appearance of a retaining wall by combining a basic sized vegetation block having a soil dressing chamber opened at the upper face with a large-sized vegetation block having a height plural times as large as the former block and stacking them. SOLUTION: A basic sized vegetation block A having a soil dressing chamber opened at the upper face is combined with a large sized vegetation block B having a height two times as large as the block A in only the vertical direction. The blocks B laterally connected as a pair of two pieces for instance are disposed at required positions laterally and vertically spaced apart. In this way, uniformity of the vegetation blocks can be eliminated and the appearance of the retaining wall can be improved and the landscape of the slope face can be greatly changed. Since a large quantity of soil dressing can be filled in the block B, large trees can be planted and a space where small animals such as birds or insects inhibit favorably can be formed. Hence a natural ecosystem can be restored.

Title: Substrate glass dividing device for display panel
Inventor: UEMATSU HIROYUKI
IPC: G02F1/13
Filed: 1993-04-16
Abstract: PURPOSE:To prevent the damage of a display panel and to improve dividing accuracy by adding at least a part of pressurization to the low part side of a level difference disposed on an arranging table for substrate glass to divide this substrate glass along a marking-off line. CONSTITUTION:The arranging table 50 for the substrate glass 9 is provided with a high part and a low part by the level difference 51. The display panel, for example, liquid crystal display panel, is arranged on the arranging table 50 and is fixed to the arranging table in such a manner that the marking-off line 11 of the substrate glass 9 is positioned along the edge of the level difference 51 of the arranging table 50. A vertically movable pressurizing means 30 is disposed in the position of a distance L in parallel with the marking-off line 11 of the substrate glass 9 on the low part side of the arranging table 50. The distance L from the marking-off line 11 is preferably as larcte as possible so that the relatively small force to be applied by this pressurizing means acts as a large bending moment on the marking-off line 11. The pressurizing means 30 is preferqbly formed to such a shape with which the force is uniformly applied on the largest possible area of the surface of the substrate glass 9 to avoid exerting a local stress on the liquid crystal display panel.

Title: Quartz glass-made jig
Inventor: INAGI KYOICHI
IPC: H01L21/22
Filed: 1986-05-16
Abstract: PURPOSE:To improve heat-equalizing and heat-resisting properties, by forming transparent layers, which essentially have no bubbles, as inner and outer surfaces and then forming a semi-transparent layer, which has fine bubbles, as a central layer inserted between both the transparent layers. CONSTITUTION:A central layer 2 having some bubbles 1 and few contents of OH groups serves to improve heat-equalizing property and dimensional stability. An outer surface transparent layer 3 (an external layer) containing many OH groups serves to prevent impurities from being diffused and transmitted. An inner surface transparent layer 4 (an internal layer) created by removing bubbles, and the outer surface 3 prevents bubbles from being generated during a washing process using hydrofluoric acid. Efficiency of an heat-equalizing effect is improved by making the number of bubbles in the central layer be 20-300per 1mm<3>. An increase in the contents of OH groups in the external layer can effectively prevent impurity diffusion, and therefore the contents of OH groups are made to be 300-2000ppm. Hence, heat-equlizing effect and dimensional stability is highly obtained in quartz glass which is composed of the outer surface transparent layer containing many OH groups to prevent impurities from being diffused and transmitted and the central layer having some bubbles and few contents of OH groups.

Filed: 1978-09-12
Abstract: PURPOSE:To improve wavelength conversion efficiency even if light energy density is small by converting the wavelength of light by the use of a fibrous optical transmission line composed of light transmittable material containing fluorescent material. CONSTITUTION:The ray 14 of a green color having spectrum with the wavelength of 5300Angstrom  as a center emitted from a light emitting diode 10 propagates in an optical fiber 11a to become input light which is then led into a fibrous optical transmission line 13. This fibrous optical transmission line 13 comprises fabricating the rhodamine 6G being fluorescent material mixed in the plastics of acrylic base having light transmittability to fiber form and bundling one or a multiplicity of the fibers. As a result, the ray 14 is absorbed in rhodamine 6G and the ray 15 of an orange color having the spectraum with the wavelength of 6000Angstrom  as a center is newly emitted, whereby the wavelength conversion of light is accomplished. The ray 15 becomes output light which then propagates in the optical fiber 11b and enters a photo detector 12.

Title: Deodorizing, decoloring, and water-absorbing body
Inventor: KOBAYASHI TAKUO
IPC: C02F11/14
Filed: 1987-05-09
Abstract: PURPOSE:To form the title deodorizing, decoloring, and water-absorbing body at a low cost by adding TABU (Machilus Thunbergii) powder, seaweed (Chondrus ocellatus) paste, and pyroligneous acid or activated carbon to fine bark powder, adding hot water to the mixture, kneading the mixture, then molding the caked mixture to an appropriate size, and drying the molded product. CONSTITUTION:When the deodorizing, decoloring, and water-absorbing bodies 11 are spread over a stool, night soil is deodorized and decolored, and all the water is absorbed. The body is capable of absorbing the water having a weight of three times its own weight. Since the bark powder is caked by a small amt. of the TABU powder of the same kind as the bark and seaweed paste and the bark is pulverized, the body 11 after absorbing water is easily decomposed in water and discharged, and hence any environmental pollution is not caused. When the bodies 11 are accumulated, an extremely high-quality compost can be obtained. The more the contained activated carbon and pyroligneous acid are dried, the more the deodorizing and decoloring effect is enhanced. Since the bark as the waste from the production of the wood chip for paper making is used as the raw material and the bark powder is caked by a small amt. of fine TABU particles, the cost is low.
