Title: Manufacture of base material for optical fiber
Inventor: MATSUDA HIROO
IPC: C03B37/012
Filed: 1982-03-23
Abstract: PURPOSE:To easily manufacture a base material for optical fiber having high numerical aperture without causing cracking, by inserting a bundle of a plurality of glass rods having a higher refractive index than a glass tube into the tube, melting them by heating, and uniting them to one body. CONSTITUTION:A bundle of a plurality of glass rods each having a small diameter is used as a core 2 in a rod-in-tube method. The glass rods have a higher refractive index than a glass tube as a clad 1. The core 2 is inserted into the clad 1, melted by heating, and united to one body to manufacture a glass base material. Since a strain produced by the difference in refractive index, that is, the difference in coefft. of thermal expansion is dispersed in the whole core, this glass base material has higher cracking resistance than a glass base material manufactured by a conventional rod-in-tube method.

Abstract: PURPOSE:To reduce the working steps and to minimize the change in stress caused by the changes in static pressure and temperature by forming a ring- shaped supporting part at the etching time of a diaphragm, and bonding the supporting part to a supporting member having a through hole. CONSTITUTION:A sensor substrate 1 is etched by using an etching mask, and a diaphragm 3 and a ring-shaped supporting part 5 for supporting the diaphragm are formed at the same time.

Abstract: PURPOSE:To enable sharp reduction of the generation of noise and vibration through offset of vibration of pumps, by a method wherein the pumps, connected to each other so as to integrally form them are arranged so that the axes of pistons cross each other at the same point and are located rotational symmetrically about the point. CONSTITUTION:Arrangement of pumps 1 and 2, connected to each other so as to integrally form them, is such that front pistons 70, 71, magnetic armatures 80, 81, and rear pistons 90, 91 are secured by mounting screws 40 and 41 so that axes thereof coincide with each other, and are located rotationally symmetrically. This causes exciting coils 160 and 161 to be alternately energized at intervals of half wave of an alternating current to alternately excite stationary electromagnets 20 and 21. As a result, when a piston 270 of the one pump 1 is attracted through excitation of the stationary magnet 20, a piston 271 of the other pump 2 is returned in a reverse direction to said attraction direction through the resilient pressure of a return spring 83. This causes vibration of pistons to be mutually attracted and offset, resulting in the possibility to sharply reduce the generation of noise and vibration.
