Title: Production of crystalline silicon nitride
Inventor: DOMOTO KAZUMI
IPC: C01B21/068
Filed: 1988-05-17
Abstract: PURPOSE:To obtain crystalline silicon nitride of high alpha-form crystal content having uniform particle shape by heating amorphous silicon nitride obtd. by the vapor phase decomposition reaction of monosilane with a specified amt. of ammonia at a specified temp. further in NH3 atmosphere. CONSTITUTION:A gaseous reaction mixture consisting of monosilane and 10-30 times mole ammonia is subjected to vapor phase decomposition reaction at 600-1,000 deg.C. If the molar ratio of NH3 to the monosilane is <10 times in this reaction, unnegligible amt. of free Si is formed. If the molar ratio if >30 ties, no advantageous result is obtd. Further, if the reaction temp. is <600 deg.C, the percentage of formation of silylene due to the decomposition of the monosilane decreases causing lowering of the yield. Moreover, danger may be caused because of discharge of undecomposed monosilane out of the system. If the reaction temp. is >1,000 deg.C, the particle shape becomes ununiform due to progress of partial crystallization together with the synthesis of the crystalline silicon nitride, causing uneconomical result of the synthesis.

Title: Dental syringe and its associated capsule
Inventor: JIYON JIEE DEISUKO JIEE AARU
IPC: A61C3/08
Filed: 1991-05-23
Abstract: PURPOSE: To obtain a dental syringe which allows preventing of excessive material from suddenly flowing by arranging an injector chip engaged with a piston of capsules to be a structure of a plunger enabling elastic loading with a spring. CONSTITUTION: A flange 33 is linked to an internal end part of an ejector 32 with a dimension enough to enter an internal cavity 29A of a shaft 29. The flange 33 keeps the ejector 32 well matched to prevent the ejector from separating from the plunger shaft 29. A compression spring 34 is arranged being engaged with the ejector 32 to apply a specified size of energizing force to the ejector. The energizing force to be applied to the ejector chip 32 by the spring 34, namely, resistance causes the ejector 32 to retract into the plunger shaft 29 when encountering a resistance larger than that of the spring. This solves a problem of the breaking and distortion of a wall part in a capsule 24.

Abstract: PURPOSE:To prevent the breakage of a tube caused by the contact of the leading end part of the closure part of a communication body with the inner wall of the tube at the time of centrifugal separation by providing an annular thin wall part for allowing a hollow body part to communicate with the tube and further forming the outer surface of the leading end part of the closure part into a curved surface. CONSTITUTION:A communication body 10 has a hollow body part 11 composed of a cylindrical body and a closure part 12 composed of an elongated shape body. The leading end of the closure part 12 is formed into a round curved surface and the left and right corners of the leading end part of the closure part 12 are also formed into round curved surfaces. Since a tube 20 to which the communication body 10 is mounted is composed of a flexible one, the inner surface of the tube 20 is brought into contact with the closure part 12 of the communication body 10 by curving the tube 20. Since the leading end part of the communication body 10 is formed so that the parts having the contact possibility with the inner surface of the tube are formed into the round curved surface and have no edge, the tube is not damaged even when the closure part is brought into contact with the inner surface of the tube 20 at the time of centrifugal separation.

Title: Production of optical fiber blank material for infrared ray transmission
Inventor: OOSAWA KAZUYA
IPC: G02B6/00
Filed: 1979-09-19
Abstract: PURPOSE:To obtain an optical fiber blank material which is not mixed with any impurity by generating nonisothermal plasma while supplying volatile silicon halide vapor and volatile chalcogen element halide vapor into a reacting tube. CONSTITUTION:While raw material gases of volatile silicon halide vapor, for example, silicon tetrachloride, volatile chalcogen element halide vapor, for example, disulfur dichloride, and inert gas and addition components are being supplied into a reacting tube made of glass, microwave electromagnetic field is applied to generate nonisothermal plasma, whereby a chalcogen glass film is formed. The raw material gases are fed steadily and are exhausted at a fixed rate. The reacting chamber is kept at about 1.0-5 atmospheric pressure. Microwaves are, for example, of 245GHz. These obviate the entry of the impurities in the atmospheric air and provide the effect that the optical fiber obtained by spinning this blank material under heating becomes the one of less optical transmission losses.
