Title: Heat resistant electric insulating material and heat resistant insulate wire
Inventor: SEGUCHI TADAO
IPC: H01B3/12
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To form a heat resistance electric material of an amorphous silicone nitride inorganic fiber substantially made of Si and N having the specified values of tensile strength and a volume resistance rate after a heat treatment in air at 1000 deg.C for a specified period so as to use the material in atmosphere of 1000 deg.C or higher. SOLUTION: A polycarbonated silane fiber having a diameter of 18μm obtained by using a spinning device is irradiated with electronic beams of 12MGy in a He gas atmosphere so as to be infusible. The fiber to be infusible after the irradiation is held in ammonia atmosphere for one hour by increasing a temperature from a room temperature to 800 deg.C at a speed of 300 deg.C/hour, then continuously switched to nitrogen gas atmosphere without contacting the air, held for one hour by increasing the temperature from 800 deg.C to 1200 deg.C at a speed of 300 deg.C/hour and then by slowly cooling this fiber, a silicon nitride inorganic fiber is obtained. This fiber is subjected to sizing with polyvinyl alcohol, then plainly woven with 20 pieces/inch in the longitudinal direction and 18/inch in the lateral direction and thereby a plainly woven tape having a thickness of 0.4mm is manufactured. This tape is wound on the outer periphery of a W conductive body at a lap of 1/2 and thereby a heat resistant insulated wire having an insulating body thickness of 1.2mm and an outer diameter of 5mmϕ is manufactured. For this electric insulating material, a tensile strength after temperature aging at 1000 deg.C for one hour is 1.0GPa or higher and a volume resistance rate is 10<12> Ωcm or more.

Title: Method of treating lignocellulose material
Inventor: ROGAA EMU ROUERU
IPC: C08B3/06
Filed: 1986-08-27
Abstract: Reaction of lignocellulosic material with acetic anhydride greatly improves dimensional stability and resistance to biological attack and is, according to the invention, made in the absence of any cosolvent or added catalyst and in a simple way. Partially dried or dry lignocellulosic material is treated with liquid acetic anhydride for a short period of time, the time being adapted to the dimension of the material used. In a fol­lowing step, any excess anhydride not impregnated into the material is removed. The impregnated lignocellulosic material is then placed in a heated chamber to yield acetylation to a predetermined weight gain. After a short period of time, again adapted to the dimension of the material, unconsumed acetic anhydride and byproduct ace­tic acid are removed from the heated chamber and reco­vered.

Title: Gas lighter
Inventor: IWABORI FUKUO
IPC: F23Q2/34
Filed: 1981-12-16
Abstract: PURPOSE:To ensure ignition of fuel of a gas lighter even under a strong wind and prevent the flame from being blown out thereby by a construction wherein the windshield of the lighter has a notch formed on a side surface thereof and the lower part of the notch swells out towards a nozzle thereby forming an upwardly directed draft passage. CONSTITUTION:A windshield 1 has a front wall 1C formed with a notch 1e, and the lower part of the notch 1e swells out towards a nozzle 6 thereby forming a draft passage within the windshield 1. When the lighter is clicked to flame, the combustion air flows through the air inlet port 1e and thence through the draft passage in the generally same direction as the flame of the lighter and into a flame nozzle 1d. At that time, the air flowining in the windshild through the air inlet port 1e is intercepted by the swelled part so that the air is not allowed to impinge directly against the nozzle 6. Therefore, a stable flame can be obtained and there is no anxiety of the flame being blown out even under a strong wind.

Abstract: PURPOSE:To prevent the generation of deformation due to a temperature rise in the fixation of leads by an insulating resin tape by dividing the tape surrounding the periphery of a pad into the plural and arranging each tape piece at a right angle to respective lead. CONSTITUTION:When a holding tape 1 is constituted of trapezoidal split pieces 2 and 3, the long side 21 of the first split piece 2 is brought to approximately the same length as each side of a pad (c) in the first split piece 2. The trapezoidal base 31 of the second split piece 3 positioned at the corner section of the pad (c) is disposed so as to be positioned at approximately a right angle to the center line (x) of the corners of the pad (c) in the second split piece 3. The whole shape organized at approximately the same slight intervals among each split piece 2 and 3 forms a regular octagon. Accordingly, each lead is held at comparatively equal distances from respective piece of the pad (c), and all leads are covered continuously with each split piece 2 and 3, thus mutually regulating the deformation of the leads resulting from the shrinkage of the tape by heat among the adjacent tapes, then effectively preventing the deformation of the leads.

Title: Coupler for optical communication
Inventor: ONOKI SEIJI
IPC: H04B10/07
Filed: 1982-11-18
Abstract: PURPOSE:To attain the switching without hit of a transmission signal and less in the insertion loss by providing a bypass circuit between branches of two directional couplers and inserting a photoelectric and electrooptic converters between other branches. CONSTITUTION:Bidirectional transmission is attained between optical transmission lines L1 and L2 via a bypass including a delay circuit DL between branches #1 of directional couplers CP1, CP2. When an amplifier is inserted between the photoelectric converters O/E1, O/E2 and the electrooptic converters E/O1, E/O2 in the branches #2, #3, a signal from the transmission lines L1, L2 is amplified and transmitted to the transmission lines L2, L1 for attaining the bidirectional transmission. Since the coupling between branches is blocked, no oscillation of detour due to amplification takes place. The bidirectional transmission is kept in the bypass of the branch #1 at a failure of the branches #2, #3, and since no switching is operated, no hit of the optical transmission is produced and since the optical transmission loss of the couplers CP1, CP2 is low, the insertion loss is reduced.
