Abstract: PURPOSE:To prevent the generation of bubbles and the disconnection of a fiber owing to a temp. change, by gathering and attaching >=3 rod-shaped electric resistance heating elements lengthwise. CONSTITUTION:An optical fiber is inserted previously into a hollowed part 10 of a reinforcing member and an optical fiber naked wire 6 in which coating layers 7, 8, 9 are removed is melted and connected. The reinforcing member is disposed so as to cover the coating layers at the both ends of a connected part 6A, and when voltage is applied to both ends of an electric resistance heating element 3, a heat-melting adhesion layer 4 and a tube 2 are melted to produce an adhesion layer 2' and at the same time a heat-shrinkable tube 1 is shrunk lengthwise and they are made in one body as expressed by a figure. Even if the tube 1 is shrunk at the heating time, air is discharged through a gap of the element 3 and bubbles do not remain in the reinforced part, as >=3 electric resistance heating elements are attached lengthwise and disposed. By this way, the disconnection of an optical fiber owing to a temp. change is prevented.

Abstract: PURPOSE:To provide a burner in which a flame temperature is lowered in average, the amount of NOx generated is reduced, turn-down ratio is high, the size is miniaturized, noise is reduced and reliability is high by forming a circular burner port body, and a plurality of air holes, and providing upright a plurality of flame holding members in the vicinity of the burner port body facing a combustion chamber. CONSTITUTION:A part of an exhaust gas emitted from swirling blue flame zones, tending to spread outward is mixed into a total primary premixed gas swirling and ejecting through air holes 33 between free gaps 33' formed between the inner peripheral wall of a burner port body 28 and swirling blue flame zones 35 at the time of combustion state. As a result, the rise in the temperature of the total primary premixed gas ejecting is promoted and a recirculating operation of making a more dilute mixed gas is generated. On the other hand, at the central portion of the swirling blue flame zone 35, as shown by broken line arrows, the recirculating operation of the exhaust gas is generated. By the recirculating operation of the exhaust gas from both the plane and cross section, generation of the local high-temperature portion in the flame zone is prevented and the flame area is widened and the heat radiating effect is improved, thus greatly reducing the amount of NOx generated.

IPC: C08G63/06
Filed: 1994-04-21
Abstract: PURPOSE:To improve long-term storage stability by adding a specific amount of sodium carbonate to a copolymer of lactic acid and either polyethylene glycol or glycerol. CONSTITUTION:Lactic acid is mixed with polyethylene glycol or glycerol, and the mixture is heated in a nitrogen stream preferably in the presence of a tin catalyst (e.g. tin chloride) to polymerize the monomers. To the thus-obtained copolymer is added 0.1-2wt.% sodium carbonate. This mixture is heated at about 150-200 deg.C for about 1-2hr. Thus, the copolymer can be prevented from being hydrolyzed by the free lactic acid homopolymer formed in the polymerization. As a result, a lactic acid copolymer having excellent storage stability can be produced. A lactic acid/polyethylene glycol/glycerol terpolymer may be produced likewise.

Title: Hydroscope with observation plane above water surface
Inventor: YANAGIMOTO YOSHIYUKI
IPC: A63B33/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To enable to easily and safely observe underwater by filling the inside of a main body formed with an observation plane and a cover, bringing up the water to make the observation plane above the water surface and equipping a float on the main body. SOLUTION: Fundamental constitution elements are an observation plane 1, surrounding cover 3, and floats 2 as shown in the diagram. Since the part surrounded by the observation plane and the cover 3 is tightly closed, water can be brought up from the water surface to make the observation plane above the water surface. Floating force to bring up water high than the water surface is obtained by the floats 2. Though the float 2 is positioned deviated to the left side in the diagram, it is because to compensate the volume of water to be brought up is larger in the left side. Thereby the observation plane 1 can be inclined to a desired inclination. In that case, the shape and the attaching position are not limited only if the observation is floated up and inclined at a desired inclination.
