Title: Thread guide
Inventor: YOSHIDA HARUO
IPC: B65H57/24
Filed: 1982-02-19
Abstract: PURPOSE:To prevent cutting or napping of threads in the course of long-time usage as well as decrease generation of the white power by forming a guide for thread of natural fiber from a sintered body with silicon nitride as its produced component. CONSTITUTION:A thread guide is formed by a sintered body with silicon nitride which has a comparative small thermal conductivity and a high hardness as  main component, i.e. a sintering of silicon nitride. In this case, this sintering of  silicon nitride is manufactured by preparing the sintering material through addition of metal oxide to silicon nitrides as a help means for sintering, adding a  certain proper amount of binders in two or more different sorts to this material  so as to mold into a desired form of thread guide, and carrying out sintering in  the atmosphere of N2 gas. Accordingly cutting or napping of a thread can be  prevented even in the course of long-time usage, as well as a thread guide with  extremely small possibility of generation of white powder caused by cutting-off  of the external surfaces of the thread can be obtained.

Title: Semiconductor device
Inventor: OTSUKI HIROAKI
IPC: H01L29/43
Filed: 1988-02-09
Abstract: PURPOSE:To realize low contact resistance, and to improve heat resistance after an at wiring is formed by shaping the laminated films of the silicide layer of a high melting-point metal or a transition metal and the boride layer of said metal to contact sections between an Si substrate and the Al wiring as barrier layers. CONSTITUTION:The laminated films of the silicide layer 4 of a high melting- point metal or a transition metal and the boride layer 6 of said metal are formed to contact sections between an Si substrate 1 and an Al wiring 7 as barrier layers from the Si substrate 1 side. That is, the resistance of the boride layer 6 of the high melting-point metal or the transition metal is lower than that of the silicide layer 4 of said metal, thus realizing low contact resistance. The boride layer 6 is hardly reacted with Al even through heat treatment at approximately 600 deg.C. The silicide layer 4 under the boride layer 6 and on the Si substrate 1 is difficult to be affected by a natural oxide film on the Si substrate 1 and organic contamination, inhibits contact resistance at a low value, and also prevents peeling from the Si substrate 1 of the barrier layers.

Abstract: PURPOSE:To improve the thermal efficiency in a coal gasification power generation plant, by preheating an aqueous slurry of a coal which is to be fed into a coal gasification oven in a cooler for a gas produced by gasification, and feeding the preheated slurry into the coal gasification oven. CONSTITUTION:A pressurized aqueous slurry of a coal is preheated by means of a gas produced by gasification, in a cooler wherein the gas produced by gasification is cooled, and is then fed into a coal gasification oven.

Title: Catalytic burning process
Inventor: KATO YASUYOSHI
IPC: F23C13/00
Filed: 1985-02-15
Abstract: PURPOSE:To improve ignitability in low temp. and prevent deterioration by heat at the same time by using catalysts and forming cross sectional area of flow paths at a catalyst vessel in such a manner that catalyst having superior low temp. activity but inferior heat resistance at the upper stream part and catalyst having superior heat resistance but low temp. activity at the down stream part and the former cross sectional area of flow path is determined to be smaller than the latter one. CONSTITUTION:Catalyst forming a catalyst layer 21A of the upper stream part is made by adding catalyst such as platinum or palladium, etc. to gamma-alumina catalyst carrier and has superior low temp. activity and on the other hand, catalyst forming a catalyst layer 21B is made by adding catalyst such as platinum to catalyst carrier such as alumina, zirconium and silicon carbide, etc. and has superior heat resistance. At the start time operation, preheated temp. of fuel gas by a preheater 14 is set up to be higher than ignition temp. of catalyst forming catalyst layer 21A and then burning reaction takes place only in the catalyst layer 21A of the upper stream part and by its burning heat, temp. of the catalyst layer 21B of the down stream part becomes higher than its ignition temp. When the flow rate is increased consecutively, fire extinction takes place at the catalyst layer 21A of the upper stream part and burning starts at the catalyst layer 21B of down stream part because gas flow velocity in the catalyst layer 21A of the upper stream part is larger than that in the catalyst layer 21B of the down stream.

Abstract: PURPOSE:To smoothen the layer thickness of a raw material and to reduce vibration by arranging an auxiliary roller on the upper face of the outer circumferential part of a rotary table between the grinding rollers and also providing a pressing means. CONSTITUTION:A raw material is supplied on the upper face of the central part of a rotary table 3A from a chute for introducing the raw material. This raw material is moved to the outer circumferential side of a rotary table while drawing a swirly locus on the rotary table 3A.

These are introduced into the gap between an auxiliary roller 20 and the upper face of the rotary table 3A as a condensational and rarefactional layer 40. While the auxiliary roller 20 is rotated so as to be raised by the layer of the raw material, it compresses the layer 40 between the circumferential face and the upper face of the rotary table 3A to form a compact layer 30. This compact layer 30 reaches the biting sides 4A of the grinding rollers 4. Stable operation is enabled by imparting high pressing force to the grinding rollers 4.
