Title: Method and apparatus for measuring transmission characteristic of optical fiber during production
Inventor: MURATA HISASHI
IPC: G02B6/00
Filed: 1983-05-30
Abstract: PURPOSE:To measure the transmission characteristic of an optical fiber continuously in a destructive manner accurately during the drawing by a method wherein a measuring light is made incident at the end of a matrix rod of an optical fiber during the production and an excitation is caused at the winding end of the optical fiber to measure the light propagated. CONSTITUTION:A modulated output light of a light source 31 as modulated and driven with a signal generator 37 is made incident into the end face of the head of a matrix rod 2. A measuring light passed through the head of the matrix rod 2 propagates through the matrix rod 2 having a distribution of refraction effeciency and reaches an optical fiber 1 being drawn. It is received with a photoelectric converter 33 fixed on a winding drum 7. A signal wave converted into an electrical signal is introduced into a receiver 35 through a rotary connector 34 and processed with a signal analyzer 36. Thus, the signal light can be detected at a sufficient signal/noise ratio by detection synchronizing the receiver 35 with a signal generator 37 for controlling or the like.

Title: Leakage detecting apparatus
Inventor: KOMATSU SHINICHI
IPC: G01M3/38
Filed: 1989-04-17
Abstract: PURPOSE:To make it possible to detect a leaking part visually by using a system which reacts with leaking liquid and emits light by the projection of light. CONSTITUTION:A leakage detecting apparatus is attached to an outer surface of an apparatus 1 having a welded part 2. An inner layer 3 of the leakage detecting apparatus comprises a semipermeable membrane which passes liquid only one direction.

Title: Magneto-optical recording system
Inventor: HOSHINA SHOJI
IPC: G11B11/105
Filed: 1991-04-25
Abstract: PURPOSE:To suppress the increase of inverted magnetic domain width which follows the increase of an inverted magnetic domain length and to suppress crosstalk by changing laser radiating pulse width corresponding to the length of the inverted magnetic domain recorded by a magneto-optical disk having no guide groove. CONSTITUTION:In this magneto-optical recording system, laser radiating pulse power is changed corresponding to the length of the inverted magnetic domain to be recorded. When the inverted magnetic domain length is short, the effect of stored heat hardly appears and when the inverted magnetic domain length is long, reversely, the effect easily appears. Since this effect considerably appears at the magneto-optical disk having no guide groove, when the inverted magnetic domain length is long, the effect is canceled and the laser power to be put into the magneto-optical disk is increased so as to decrease a heating amount per unit length of the inverted magnetic domain length and to decrease the inverted magnetic domain width. Since the laser power of the shortest inverted magnetic domain by utilizing this fact and the laser power is decreased with the increase of the inverted magnetic domain length, the inverted magnetic domain width is controlled, and the inverted magnetic domain width can be prevented from being increased with the increase of the inverted magnetic domain length.
