Title: Production of porous glass preform for optical fiber
Inventor: TERAJIMA MASAMI
IPC: G02B6/00
Filed: 1995-05-26
Abstract: PURPOSE: To improve production efficiency of the preform by moving plural burners which are provided with a mechanism for reciprocating the burners as one body in the longitudinal direction of a starting core member, in the radial direction of a deposited body on the core member with the increase in diameter of the body. CONSTITUTION: In this production, a rotating core member such as quartz glass rod is placed in a closed type reaction furnace, and also, plural oxyhydrogen flame burners reciprocating in the longitudinal direction of this core member are arranged in a row at prescribed intervals. Prescribed flow rates of gaseous oxygen, gaseous hydrogen, a carrier gas and SiCl4 or the like are supplied to the burners and formed fine glass particles are deposited on the core member to form a porous glass preform on the core member. Thereafter, the weight of the porous glass preform, that increases with the increase in diameter of the preform, is measured to calculate the preform outer diameter by using an arithmetic unit. Based on this calculated value, each of the burners is moved in the radial direction of the preform so as to arrange the burners in two rows. At this time, flow rates of the gases are also increased while controlling the flow rates so that each of the flames does not interfere with the others to continue the deposition of fine glass particles and to produce the objective preform.

Title: Beam energy absorbing apparatus
Inventor: JINNO MASABUMI
IPC: G21K1/10
Filed: 1991-05-30
Abstract: PURPOSE:To absorb energy of high energy beam at high efficiency by installing a turbo-molecular pump and a rotating body which is rotated by its rotating shaft in the route of the beam. CONSTITUTION:A rotating body 10 in the inside of a beam pipe 11 in highly vacuum condition is rotated using the rotating force of a turbo-molecular pump 12 as the driving force and absorbs beam energy. The pump 12 is composed of a housing 13, a stator 14 fixed in the inner wall of the housing, a motor 16, and a rotor 15 fixed in a shaft 17 to be rotated by the motor. The rotor 15 and the stator 14 respectively have blades in a plurality of stages and the gap between each stage is narrow and the each blade is attached at an angle. As a result, when the shaft 17 is rotated at high speed, the gas in the highly vacuum side is discharged to the low vacuum side. Since the bearings 18, 19 to support the shaft 17 exist in the low vacuum side, the steam of a lubricating oil does not lose the high vacuum condition. Meanwhile, since the beam radiates the side surface of the rotating body 10, it absorbs the energy efficiently without being damaged even in the case of highly intense beam energy.
