Abstract: PURPOSE:To prevent a connection loss of an optical transfer quantity in case of junctioning an optical fiber, by finishing a cut end face of an optical fiber made of plastic, to a specular surface having no burr. CONSTITUTION:A fiber 1 is fitted into a lead-in hole 9, is led into a cylindrical guide 5, also is inserted through a burr cut ring 3, and as for its tip part, a finish allowance delta of the end face is projected from a knife part 10. The final finish allowance delta1 is a total of delta and delta2 in the knife part 10. As for the part of the finish allowance delta1, a burr 8 is generated on the outside circumference of the knife part 10. Subsequently, a specular surface of a specular surface plate 6 is cooled by a cooling device consisting of a cooling pipe, and when the specular surface plate 6 is slide-moved backward to the opposite fiber 1 side after the end face of the fiber 1 has been cooled enough, the burr cut ring 3 cuts off the burr 8 generated up to the finish allowance delta2 pushed up by a reduction resisting spring 4, so as to extrude from the end part of the fiber 1.

The lump of rubber and the vulcanizer are converted to powder by the concurrent action to fluidize and knead them. In addition, during the vulcanization, numerous bubbles are formed by trapping air in the rubber and emerge on the surface when the rubber is pulverized resulting in the formation of an uneven part and a hollow part on the surface of the powder rubber. The particle size of this powder rubber is about 200-700μm and the bulk specific gravity is about 0.15-0.3g/cm<3> .

Title: Gas shut-off valve
Inventor: OHASHI NORIYOSHI
IPC: F16K31/06
Filed: 1986-09-12
Abstract: PURPOSE:To prevent a malfunction due to an external impact and the like by taking a large difference between an adsorption force in a zero current and that at an operation point. CONSTITUTION:When an electric current runs instantaneously in an electromagnetic coil 6 and releases adsorption with a plunger 9 and the magnetic force of a permanent magnet 2 on a core piece 3, a magnetic flux generated by the electric current running in the coil 6 flows in the plunger 9, the core piece 3, a heel piece 7a, a yoke 1 and another heel piece 7b. Therefore, magnetic reluctance becomes small by a magnitude corresponding to the magnetic current passage of the heel piece 7a, when viewed from the coil 6. As a result, a magnetic flux generated by the coil 6 passes the adsorption surface of the plunger 9 and the core piece 3 by a magnitude larger than a case without a heel piece, and it becomes possible to obtain a larger difference between an adsorption force at a zero current value and that at an operation point.

Title: Nitride film forming apparatus
Inventor: MENJIYU ATSUHIKO
IPC: C04B41/00
Filed: 1982-12-11
Abstract: PURPOSE:To allow a nitride film having a uniform thickness and a good quality to be formed on the wafer surface at high speed, by standing a shielding plate of a semiconductor on an end portion of a support which is closer to a transport tube such that the surface of the shielding plate is orthogonal to the longitudinal direction of a reaction tube. CONSTITUTION:A silicon substrate 26 having an outside diameter larger than that of each wafer 25 is stood on an end portion of a support 24 which is closer to a transport tube 20 such that the surface of the substrate 26 is orthogonal to the longitudinal direction of a reaction tube 21. Thus, when a nitride film is formed on the surface of each wafer 25, the flow of the activating nitrogen gas generated in a discharge tube 18 and the microwave existing in a waveguide 15 are prevented by the silicon substrate 26 from directly hitting the wafers 25, thereby allowing a nitride film having excellent element characteristics to be formed on the surface of each wafer 25. For example, the thickness of an Si3N4 film increases in proportion to the substrate temperature in the case where a silicon substrate is employed as a wafer and the substrate temperature is varied under the following conditions: CF4 gas is supplied at a rate of 100cc/min and a mixing rate of 0.1% with respect to N2 gas; the pressure is 1.0Torr; and the microwave power is 1.3kW.

Abstract: PURPOSE:To make it possible to obtain hot water heated up to a desired set temperature even when the amount of solar radiation is small by supplying heat from a collector one by one successively to a plurality of latent heat utilizing heat storage devices to put the same into a stored heat saturated state. CONSTITUTION:When the heat supplied to a heat storage device 4, an internal gas 13 of a vessel 11 expands due to heat received from a heat transfer liquid 9 and the vessel 11 also expands. When a main body 8 of the heat storage device is put into a heat storage saturated state, a bellows part 10a is contracted due to the expansion of the vessel 11 and a metal part 10b comes into contact with a heat pipe 12. Then, other heat storage device 4 adjacent to the heat storage device 4 which is in a heat storage saturated state is connected to a collector 6. When the heat storage device 4 newly connected to the collector 6 is put into a heat storage saturated state, the next adjacent heat storage device is connected to the collector 6 in a similar manner to the case of the previous heat storage device 4. Even when the amount of heat radiation is small and the amount of heat collected is small, at least one heat storage device 4 is put into a heat storage saturated state, and hot water heated to a set temperature is obtained.

Abstract: PURPOSE:To realize a shallow junction for allowing a bipolar transistor with a high cut-off frequency to be produced by forming a high-concentration collector region at an emitter-equivalent region by epitaxial growth. CONSTITUTION:After an oxide film 2 is allowed to grow on an N-type semiconductor substrate 1 which is subjected to epitaxial growth, a high-concentration N-type epitaxial layer 4 is selectively allowed to grow within an opening 3 of an emitter-equivalent region. Then, a low-concentration N-type epitaxial layer 7 is selectively subjected to epitaxial growth around the high-concentration N-type epitaxial layer 4. Then, a P-type epitaxial layer 9 is formed at an element region. Then, an N<+>-type emitter region 12 is formed by introducing N-type impurities into the P-type epitaxial layer 9. In a section A which passes through the emitter 12, impurities concentration of the high-concentration N-type epitaxial layer 4 is extremely higher than that of the low-concentration N-type epitaxial layer 7 at a section B, thus enabling a cut-off frequency of a bipolar transistor to be high and capacity to be reduced and voltage resistance to be increased.
