Title: Preparation of base material for optical fiber
Inventor: YANASE TOMOO
IPC: C03B37/018
Filed: 1980-06-21
Abstract: PURPOSE:To reduce the hydroxyl group content without reducing the productivity in initiating the oxidation reaction by the vapor phase axial deposition method for preparing a base material for an optical fiber, by adding an inert gas to a combustion flame of carbon monoxide gas and oxygen gas. CONSTITUTION:Fine mixed glass powder of SiO2 with GeO2 and P2O3 are jetted from a core oxyhydrogen burner 11 with argon as a carrier gas, and carbon monoxide gas and oxygen gas are fed thereto. Fine mixed glass powder of SiO2 with P2O3 are then jetted from a cladding oxyhydrogen burner 12 with argon gas, and carbon monoxide gas and oxygen gas are fed thereto. A sintered glass body 13 is thus formed and then deaerated by heating with a heater 14 to give a transparent base material 15 for an optical fiber. The burners 11 and 12 have such a structure as to prevent the deposition of the gaseous glass raw material at the jetting port 21 by enclosing the periphery of the gaseous glass raw material with argon gas jetted from a jetting port 22 on jetting of the gaseous glass raw material from the outlet 21. The deposition efficiency of the raw material is improved by reducing the temperature of the combustion flame by the carbon monoxide gas and the oxygen gas jetted from jetting ports 23 and 24.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To surely detect evaporation fuel concentration by changing a combustion operation into homogeneous combustion operation, in the case where evaporation fuel concentration is detected by carrying out purge during lean combustion operation. SOLUTION: A purge control valve 38 for controlling an evaporation fuel rate led into an intake system according to an engine operating condition is interposed in a purge passage 37 for purging evaporation fuel generated from a fuel tank 31 into the intake system of an internal combustion engine.

Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of the suspended matters, etc., in sewage to the inside surfaces of a screw shaft and hollow shaft by stopping an electric motor at and for a specific number of times and a specific time per day when operating an aerator having the hollow shaft to be rotated by the motor. SOLUTION: The screw type aerator used in a sewer and sewage treatment plant is constituted by disposing an electrically driven valve 6 at one end of the hollow shaft 1 rotationally driven by the motor 5 and forming the screw 2 at the other end. A negative pressure is generated at the front end of the screw 2 by the water flow induced by the rotation of the motor 5 and the air in the atmosphere is sucked out of the front ends of the vanes of the screw 2 through the motor 5 and the hollow shaft 1 at the time of opening of the electrically driven valve 6 by the negative pressure. At the time of operation of such aerator, the motor is stopped at >=1 times per day for 10 minutes at a time.  As a result, the deposits, such as suspensions, adhered to the inside of the hollow shaft 1 are immersed into the sewage for the specified time and are softened and thereafter, the deposit are blown off by the air flow at the time of aeration.

IPC: G03B27/62
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To regulate the opening angle of a pressing plate and to stably open the pressing plate at the opened position thereof. SOLUTION: The upper surface 1a of a device body 1 is provided with a regulation member 46 for regulating the opening angle θ of the pressing plate 21 in a state where it abuts on the side surface 21b of the plate 21 on a hinge 22A side when the plate 21 is opened. Thus, since the weight of the plate 21 is received by the body 1 through the regulation member 46 because the side surface 21b abuts on the regulation member 46 and the opening angle θ of the plate 21 is regulated when the plate 21 is opened, the opening angle is regulated in a state where the plate 21 is stably opened. Besides, since the generation of rotational moment with the turning supporting points of the hinges 22A and 22B as a center can be suppressed, the hinges are prevented from being damaged when the plate 21 is opened and closed.

Abstract: PURPOSE:To decrease the variation of the serial equivalent resistances at a low exciting level as well as the frequency change under the manufacturing process, by  providing the secondary electrode for fine adjustment of the frequency only at the  area excepting the part near the position where the displacement of vibration be comes maximum. CONSTITUTION:Secondary electrodes 221 and 221' are stacked to main electrodes 22 and 22' of diameter D1 having lead-out parts 200 and 200' on both surfaces of crystal plate 11 and within circular width W excluding the center part and in the inside along nearly the outer edge of the main electrode. Electrodes 221 and 221' are formed by taking out the oscillator once into the air after production of the main electrode and thus in the considerably worse condition than the main electrode. In this case, electrodes 221 and 221' are formed in the range insensitive to the vibration, and thus the evil effect due to the deterioration of the electrode can be reduced extremely. Thus a very high stability is secured to the variation of the serial equivalent resistances at at a low level, the frequency change due to the sealing of the case and the frequency change due to the aging respectively.
