Title: Production of silicon nitride powder
Inventor: FUJII HIDENORI
IPC: C01B21/068
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain a high α-conversion rate, a high nitriding rate and high suitability to comminution by previously molding metallic silicon as a starting material into a granule shape and carrying out direct nitriding by a fixed bed system with a reactive gas contg. a source of nitrogen. SOLUTION: Water and an org. binder are added to metallic silicon having 1-30 μm, preferably 2-15 μm average particle diameter and <=45 μm max. particle diameter and they are wet-mixed and molded in a granule shape by a method such as rolling or extrusion. The org. binder is, e.g. PVA or an acrylic resin. The molding is controlled so as to obtain granules having 0.3-0.7g/cc, particularly 0.4-0.6g/cc apparent density and 30-70%, particularly 35-60% porosity. The shape of the granules is not particularly limited. In the case of columnar granules obtd. by extrusion granulation, the pref. diameter is 0.3-3mm, in particular 0.5-2mm. The granules are dried and directly nitrided by a fixed bed system with a reactive gas contg. a source of nitrogen at <=1,400 deg.C, preferably 1,250-1,300 deg.C.

Title: Heat treatment device for semiconductor wafer
Inventor: HIRASAWA SHIGEKI
IPC: H01L21/205
Filed: 1986-05-06
Abstract: PURPOSE:To effectively utilize heat by heaters and besides uniformize wafer temperature, by installing reflective members large in reflection factors between side heaters and end parts of a device, and then installing coneshaped and heat-equalized members large in heat-absorptive and heat-radiative factors and the like between the side heaters and the wafers. CONSTITUTION:Heat generated by side heaters 1a and 1b is conducted to a heat- equalized tube 2, and besides conducted from the heat equalized tube 2 to cone-shaped and heat-equalized members 8. Because the heat-equalized members 8 are large in heat-absorptive factors, temperature of them quickly rises with the heat by the side heaters 1a and 1b. The heat is conducted from the insides of the heat-equalized members 8 to the wafers 4a and 4b, which exist on axial end parts, out of ones arranged in numbers. On the other hand, though the heat generated by the side heaters 1a and 1b is also conducted by way of the heat-equalized tube 2 to cone-shaped reflection members 9, the amount of heat conduction is small because the reflection members 9 are large in heat-reflective factors. Hence, the respective actions of the cone-shaped and heat-equalized members 8 and reflection members 9 enable the heat by the side heaters 1a and 1b to be effectively conducted to the wafers 4a and 4b on the axial end parts, besides capable of reducing the amount of the heat radiated to the axial end parts of the reaction tube 3.

Title: Knapsack for school use
Inventor: MIWA HIROSHI
IPC: A45C3/02
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent permanent set by fatigue through reinforcement of a curved region and conceal crackings, by affixing overlappingly in a single piece a flexible reinforce cover plate whose base end edge is fixed, to the top of the back plate. SOLUTION: The flexible reinforce cover plate 10 is overlapped so as to cover the whole surface of a curved region of a covering lid 8 covering an opening 6 in the oversurface of an accommodation part 1. The cover plate 10 has a surface consisting of an oxide colored and lustered to the same color as the skin 8b and affixed to its surface by a bonding agent or two-side adhesive tape. The base end edge of the cover plate is folded back in such a way as enwrapping the base end of the covering lid 8 and sewn on the back plate 2 solidly. Because the base end edge of the cover plate 10 is secured to the top of the back plate 2 and affixed overlapped to the whole surface of the curved region of the lid 8, the part with curved region to be folded repetitively is particularly reinforced, and generation of a permanent set in fatigue can be precluded.  Even if the skin 8b of the lid 8 is of cordovan leather, crackings apt to occur in the part with curved region can be concealed.

Abstract: PURPOSE:To obtain economically moldings which have good strength and accurate dimensions and do not cause extreme degradation in the properties of Al- base metal, by pressure molding the Al-base metallic powder compounded with  a thermosetting resin and allowing the resin to set. CONSTITUTION:The composite powder consisting basically of Al powder or Al alloy powder and compounded with 2-12wt% thermosetting resin is pressure molded to a required shape. At the same instant of or after molding, the thermosetting resin is allowed to set. Further, about 1-8wt% MoS2 is compounded in the composite powder, to improve moldability and to solve problems such as galling of dies. Here, if the thermosetting resin is too little, it is not possible to obtain the moldings of sufficient strength, and if it is too much, the improvement in strength cannot be expected and there are problems such as exudation on the outside surfaces of the moldings and the consequent degradation of properties. This method is suitable for production of parts of intricate shapes such as brackets of motors.
