Abstract: PURPOSE:To reduce the transmission loss of an optical fiber by adding a small amt. of C to F-SiO2 glass forming the clad part of an SiO2 core/F-SiO2 clad type base material for the optical fiber. CONSTITUTION:A base material for an optical fiber is composed of a core part made of high purity quartz glass and a clad part made of high purity quartz glass contg. added F and C. The pref. amt. of C in the C added F-SiO2 glass is 0.01-1wt.% and the amt. of F is not especially limited. In the case where the difference in refractive index between the core and clad parts is 0.3-1%, the F content in the clad glass is 0.9-3%.

Title: Equipment for generating micro bubble
Inventor: KATO YOJI
IPC: F15D1/02
Filed: 1995-02-21
Abstract: PURPOSE: To improve the efficiency to generate the bubble-water mixed fluid by providing a whirling flow generating means to be inserted in a fluid transfer pipe provided with a number of pores, and feeding the compressed air from the pores and ejecting it to increase the moving speed of water in the vicinity of the pores to frequently cut the air flow. CONSTITUTION: When a pressurized water feeding system 1 is operated, the sucked sea water, etc., is pressurized to feed the water into a fluid transfer pipe 3, and the flowing water is generated in the fluid transfer pipe 3. The whirling force is given to this flowing fluid by whirling blades 4 to generate bubbles. The bubble-water mixed fluid is transferred to a bubble-water mixture ejecting part 6 to be ejected into the seawater. When a compressed air feeding system 2 is operated, the compressed air is fed into an air plenum part 5a of a gas chamber 5 through a compressed air feed pipe 2a, and ejected into the flowing water from a number of pores 3b. The air flow crosses the whirling flow to generate the phenomenon that the air flow is cut by the whirling flow. As a result, a number of bubbles of small diameter are generated.

Abstract: PROBLEM TO BE SOLVED: To enable a waist bag to be always almost in the perpendicular condition regardless of various working postures of a welding worker, by equipping a universal fitting between the main body of a waist bag for welding work and a belt loop. SOLUTION: The main body 1 of this waist bag for welding work is formed of a tough material such as leather, etc., formed into a cylinder, has a bottom part 2, and an opening 3 at the upper part. On the upper periphery part of the main body 1, a main body attaching piece 8 made of the material same as the main body is firmly attached, and by using a universal fitting 10 constituted of a fitting 11 in the main body side, a fitting 12 in the belt side, a connection ring 13 is used to connect the main body attaching piece 8 to the fitting 11 in the main body side, and a belt loop 9 and the fitting 12 in the belt side are integrally connected. On use, the belt is passed through the belt loop 9 and the belt is wound around the waist of a welding worker and a proper amount of welding rods are stored in the storing part 4.  Thereby the main body 1 is always held in almost perpendicular condition to prevent welding rods from falling during working even when the waist part of the welding worker is tilted front, rear, right, and left.

Title: Liquid atomization device
Inventor: KAWAMURA YOSHIO
IPC: B05B7/04
Filed: 1979-03-20
Abstract: PURPOSE: To effect efficient atomization by having liquid jet stream collide against a distribution plate and by atomizing with high-speed gas flow.  
     CONSTITUTION: Liquid to be atomized is supplied from liquid supply pipe 3. High pressure gas is supplied from gas supply pipe 4. Liquid jetted from nozzle 6 collides against around the center of distribution plate 7 and is blown by gas stream which flows at high speed in passage 5 outside the liquid supply pipe 3. As a result, liquid  is sufficiently atomized and is jetted out of the outlet 2 together with gas. In this  manner, gas flow energy is efficiently transmitted to liquid fuel so as to effect  effective atomization.

Title: Surface acoustic wave element
Inventor: MURATA RYOJI
IPC: H03H3/08
Filed: 1985-02-21
Abstract: PURPOSE:To make a specific frequency of an SAW element constant by providing a thermally deforming force providing means whose electrode face of a substrate is curved to be a concaved face attended with temperature rise to a piezoelectric base provided with a comb-line electrode to the surface. CONSTITUTION:The SAW element 3 is placed movably on supports 2, 3 on a base 1. The SAW element 3 is formed by providing a comb-line electrode 5 to the surface of the piezoelectric substrate 4 made of a material such as LiNbO3, LiTaO3, BaTiO3 or PbTiO3, and a curved plate 6 whose thermal expansion coefficient is larger than that of the piezoelectric substrate 4 is adhered unifiendly with the rear face of the piezoelectric substrate 4 as a thermally deforming force providing means whose electrode face is curved to be a concaved face at temperature rise. When temperature rises, the piezoelectric substrate 4 is expanded and the pitch between the electrodes tends to increase, but since the expansion quantity of the curved plate 6 is larger then that of the piezoelectric substrate 4, the SAW element 3 is curved so that the electrode face is a curved face and the pitch is kept to the same pitch as that before temperature rise. When the temperature falls down, the SAW element 3 is restored to the original state by the reverse operation. Thus, stable operation is attained.

Title: Soiling preventive for building material and method for preventing soiling
Inventor: KATO TAKASHI
IPC: E04F13/02
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a soiling preventive which makes building materials resistant to soiling due to soiling substances and easily cleanable even when the materials are soiled by such substances by diluting a fluororesin emulsion having specified solid content and water content with a specified amt. of water. SOLUTION: A fluororesin emulsion of which the content of solids including a fluororesin is 10-35wt.% and in which water accounts for 60-70wt.% of the rest is diluted with water in a wt. ratio of the emulsion to diluting water of (10/90)-(80/20), thus giving the objective preventive. Building materials providing the external appearance of a building (e.g. a house), such as wallpaper, papered sliding doors, and woody pillars, are prevented from soiling with this preventive. A commercially available fiber protecting agent is used as the fluororesin emulsion. Such a fiber protecting agent can not be used as it is since a trouble such as yellowing occurs; however, suitable dilution with water gives an excellent soiling preventive.
