Title: Optical fiber bundle
Inventor: KOMOTO KATSUTOSHI
IPC: G02B6/04
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To make it possible to manufacture a polarization maintaining type optical fiber bundle having a good polarization maintaining characteristic and high tensile strength. SOLUTION: The circumference of the polarization maintaining optical fiber 10 is reinforced with an adhesive 31 having a high adhesiveness from above a coating 12 on the rear side of a capillary 20. If the optical fiber is formed in such a manner, the inside of a capillary 20 is only the adhesive 30 of a small Young's modulus and the high tensile strength may be obtained. Since the adhesive 31 having the high adhesiveness has usually the large Young's modulus, the adhesive 31 needs be applied on the fiber from above the fiber coating 12 such that the adhesive may not degrades the polarization maintaining characteristic.

Title: Flow rate regulating valve
Inventor: MUTO YOSHITAKA
IPC: F15B21/10
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To slowly lower a lift cylinder even if a slow return valve mechanism is completely closed by bypassing a first inflow and outflow port and second inflow and outflow port through a minimum flow rate compensating path. SOLUTION: A valve body (b) is formed with an orifice (h) affording communication between first and second communication holes 10, 11. When a change-over valve is changed over to connect the first inflow and outflow port 6 side to a tank, pressure fluid in a lift cylinder 9 is returned to the tank. Then, the pressure at the lift cylinder 9 side acts on a pressure chamber 16 and a spool 12 holds a position in which the pressure action is balanced with a spring force of a spring 14, while the opening of the first communicating hole 10 is determined in the balance position and the lowering speed of the lift cylinder 9 is controlled according to the opening.  However, when the pressure at the lift cylinder 9 side is higher than necessary one, the spool 12 is largely moved to close completely the first communicating hole 10 while the lift cylinder 9 is slowly lowered since the returning fluid flows through the orifice.

IPC: H01L21/336
Filed: 1993-10-25
Abstract: PURPOSE:To give excellent crystallizability, having little defects caused by oxygen, to the polycrystalline silicon film of a channel region. CONSTITUTION:After formation of a non-single crystal silicon film 12 has been formed, many defects caused by oxygen are present in the polycrystalline silicon film 13 which was heat treated in inert gas or oxidizing gas in the state wherein the surface of the non-single crystal silicon film 12 is exposed. However, as heat treatment is conducted in the mixture of hydrogen gas and inert gas or in hydrogen gas, the defects in crystal can be recovered by the effect of thermal annealing. The oxygen concentration on the film surface is decreased by the reduction by hydrogen of the natural oxide film on the surface of the silicon film, the concentration gradient of the oxygen in film is increased, the oxygen in the silicon film is outwardly diffused efficiently into atmosphere, and a polycrystalline silicon film 13c, having low oxygen concentration, can be obtained. This polycrystalline silicon film 13c has little defect caused by oxygen and has excellent crystallizability.
