摘要： PROBLEM TO BE SOLVED: To easily and properly treat the excess length portion of an optical fiber cable core under the application of simple constitution. SOLUTION: At the time of winding the excess length portion of an optical fiber cable core 30, the open periphery 61 of a dome type fixing member 60 is directed up and a takeup aperture widens for a takeup part 50. As a result, a winding work can be done in a short time. At the same time, the open periphery 61 comes in elastic contact with the optical fiber cable core 30, upon the completion of a winding process for the excess length portion thereof, when the fixing member 60 is reversed, thereby pressing and fixing the core 30 to the tray surface of the tray body 11 of an excess length treatment tray 10.

摘要： PROBLEM TO BE SOLVED: To easily and securely remove a secondary coating without flawing a primary coating. SOLUTION: The coated optical fiber is temporarily fixed with a clamper 50, so the coated optical fiber can be drawn by one hand and set along a groove 40, so that the coated optical fiber can easily and securely be mounted in the groove 40. Cutter holders 60 and 70 are arranged without overlapping vertically with each other, so their cutting blades 61 and 71 never interfere with each other and cuts into the coated optical fiber by the cutting blades 61 and 71 are always held constant in quantity. Rubber plates 62 and 72 provided at the bottom parts of the cutter holders 60 and 70 absorb the clearance of the coated optical fiber, so the cuts into the coated optical fiber are formulated. A pushing block 80 presses the coated optical fiber against the cutter holder 70, so a secondary coating on the side of the cutter holder 70 of a rear stage can properly and securely be removed.

摘要： PROBLEM TO BE SOLVED: To further improve the sensitivity of a hydrogen gas sensor, which uses a lithium trititanate sintered body. SOLUTION: The hydrogen gas sensor 1 comprises a substrate 2 comprising a lithium trititanate sintered body, which carries implanted gas ion, and two electrodes 3a and 3b formed, away from each other, on the same surface or opposed surfaces of the substrate 2. Although the lithium trititanate sintered body has a property wherein an electric resistance changes according to change in hydrogen gas concentration, a resistance change becomes larger by carrying an implanted gas ion, so that detection sensitivity increases significantly.

摘要： PROBLEM TO BE SOLVED: To carry out subsidiary wire anchoring work safely for a short time. SOLUTION: While a subsidiary wire 21 is inserted in each gap between base plates 60, 70 and 80, an end part of the subsidiary wire 21 is taken out on the upper face side of the base plates 60, 70 and 80, and thereby the end part of the subsidiary wire 21 is fixed on the upper face side. In this way anchoring work for the subsidiary wire 21 using an anchor member 50 is carried out easily. Since the anchoring work for the subsidiary wire 21 is carried out on the ground, the anchoring work is carried out safely for a short time.

摘要： PROBLEM TO BE SOLVED: To improve workability in the case that a cable code is connected with a slit terminal, and prevent the falling-out of a cable cord from the slit terminal which is to be caused by a tensile force, by installing a cable cord holding hole, a terminal holding hole, and a connection hole for a slit terminal which is inserted into the terminal holding hole, in a block body. SOLUTION: A cord holding hole 2, terminal holding holes 3, 4, and a connection hole 5 into which a slit terminal 32 of a connection segment 31 is inserted are installed in a block body 1. Two terminals 21a of a cable cord 21 are inserted from the aperture 2a direction of the cord holding hole 2, and protruded from the other face 1b of the code holding hole 2. The adjacent part of the terminal 21a of the cable code 21 is held in the cord holding hole 2. The terminal 21a of the cable cord 21 protruded from the cord holding hole 2 is turned back in a U-shape, and inserted into the terminal holding holes 3, 4. The slit terminal 32 of the connection segment 31 is inserted from the connection hole 5 of the block body 1, and the cable code 21 is connected with the connection segment 31.

摘要： PROBLEM TO BE SOLVED: To perform selection switching accurately and surely even in case that the output voltage on controller side is made small to its indispensable minimum, and lower price of the system. SOLUTION: This selection circuit is so arranged as to be turned on only in case that the selection control signal detected by a first voltage detector 22 is wrong and to eliminate a wrong signal instantaneously by principally a second overvoltage protective circuit 27, so the wrong operation of selection by a relay part 25 and a relay contact circuit caused by a wrong signal can be prevented. Moreover, in the case that the voltage of the selection control signal from a controller 10 is normal, the elimination of a normal selection control signal is possible only by the first overvoltage protector 26, so even in case that the output voltage on the side of the controller 10 is small, the selection of the destination by the relay part 25 and the relay contact circuit is performed surely, so the cost down of the system can be materialized.
