Title: Production of optical fiber coupler
Inventor: SASAKI KAZUYA
IPC: G02B6/28
Filed: 1987-03-06
Abstract: PURPOSE:To produce the title highly reliable coupler by heating and drawing two parallel optical fibers each consisting of the core of high-purity quartz glass and the clad consisting essentially of boron to integrate both fibers. CONSTITUTION:The clad 3 consisting essentially of boron is provided around the core 2 of high-purity quartz glass to form the optical fiber 1. The two optical fibers 1 are combined in parallel, heated, and drawn in the lengthwise direction to integrate both fibers. GeO2 and P2O5 are added to increase the refractive index and m.p. Since the clad material has a low m.p., the outer periphery is almost rounded when the two fibers are combined, and the deformation of the core is reduced. Accordingly, a highly reliable coupler can be easily produced.

Title: Method and device for estimating insulating failure fault position for balanced cable
Inventor: OTSU YUICHI
IPC: H04B3/46
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To estimate an insulating failure fault position from within a station, without dispatch not depending on the length of a measuring line by previously connecting a change-over switch to the end of a core, remotely operating it with a pulse signal and executing shorting connection corresponding to a fault. SOLUTION: One end of a shorting element 1a is previously connected to a core 2a. At the time of estimating a fault position, the pulse signal is transmitted from within the station and a change-over switch 1b of the shorting element 1a is operated. The core 2a and a core 2b (connection point 5b) or the core 2a and a ground 2c (connection point 5a) are shorted. Although the shorting element 1a is usually in an open state, the pulse signal is received and sorting is constituted. In the case of an insulating failure 3a between the core 2a and ground 2c, the change-over switch 1b is connected with the connection point 5b. A measuring end 5c is connected, without the core 2b and a measuring end 5d with the core 2a. Resistance is measured by the measuring method of a varley method or the like, and the insulating failure fault position is measured.

Abstract: PURPOSE:To disconnect a connection line which is necessary at the time of detecting a fault in hardware by disconnecting a part of or the whole connection line concerned from an external part by means of the stop command of a fault processor which can program a processing operation. CONSTITUTION:When the fault processor 40 receives a supervisory result concerning the occurrence of the fault, it outputs the command instructing the stop of a function concerned. A command reception register 22 instructs a data transfer control part 21 of the stop of a control content concerned and a processing accompanied by the stop, and instructs gate parts 23-26 concerned to disconnect the connection line from the external part. When the command reception register 32 of a system controller 30 outputs the command concerning the stop of the function, the fault processor 40 informs a system controller 20 to succeed the prescribed processing from the system controller 30. Thus, the fault processor which can execute programming by software connected to the system controller can disconnect the system controller at an optional timing.

Abstract: PURPOSE:To independently and precisely adjust the azimuth and gate of a magnetic head under a condition where they do not interfere with each other, by supporting one adjusting plate for fixing the magnetic head with another adjusting plate whose height is adjustable to the fixed section. CONSTITUTION:When the distance from fulcrums 7 and 8 to the position A of a height adjusting screw 9 is set to (a) and distance from the fulcrums 7 and 8 to the position B of a fulcrum 3 is set to (b) and the height of an adjusting plate 6 is changed by Y at the position A by adjusting the screw 9, the height of the position B of another adjusting plate 2 is changed by b/a.Y.
