摘要： PURPOSE:To allow stable light transmission with a lens transmission loss even at an extremely low temp. by constituting the cable by using optical fibers formed by loosely housing coated fibers coated with a UV curing type resin into metallic tubes. CONSTITUTION:The coated optical fibers 3 of the optical cable to be used for LNG storage facilities, etc., are constituted by loosely housing the optical fibers 1 primarily coated with the UV curing type resin having a good low-temp. charactersitic into the metallic tubes 2 having a low coefft. of expansion. The optical cable 8 for cryogenic service is formed by using such coated optical fibers 3. Since the shrinkage of the metallic tubes 2 is thereby lessened even under the extremely low temp., bending and side pressures are not applied on the fibers 1 and the increase in the transmission loss is prevented. Since the construction is of a loose type, the fibers 1 are kept free from the side pressures even when subjected to abrupt external forces, such as bending, at the time of cabling.

摘要： PURPOSE:To directly perform measurement (monitoring) while a sample is allowed to flow by measuring the concn. of the sulfide type smell imparting agent added to coal gas using a sulfide type smell sensor. CONSTITUTION:At the time of non-measurement, a valve 6b is closed and air is always allowed to flow to a measuring line 7 from a line 2. Only at the time of measurement, the valve 6b is opened and a valve 6a is closed and the sample gas from a line 1 is mixed with the air introduced from the line 2 through a line 6 within the range of detonation concn. or less to be allowed to flow to the measuring line 7. A smell sensor 9 has a property reduced in its electric resistance value when the concn. of sulfide (smell) is high and sends the electric signal corresponding to the concn. of sulfide (smell) in gas to be measured to a control apparatus 10. From this result, smell imparting concn. is cleared. Measurement is carried out at a definite time interval and, at the time of non-measurement, air is allowed to flow to the measuring line 7 to regenerate the smell sensor 9. By this constitution, a measuring cost is reduced and the accuracy of the sensor is enhanced.

摘要： PURPOSE:To continuously and economically determined the concentration of the odorant in city gas having a sulfide odorant incorporated therein by using an odor sensor to measure the sulfide odorant in a sample of the gas mixed with air and having regulated pressure and temperature. CONSTITUTION:On the downstream side of a heating means 12, a measuring line 7 is divided into two, each of which is provided with an odor sensor 13 and a switching sensor 15. When the sensitivity of the odor sensor 13 on one side lowers, it is possible to switch over to the odor sensor 13 on the other side by means of a change-over valve 16 to make measurement. Air is blown into the measuring line out of operation through a regeneration line 17 to perform regeneration. The regeneration is effected by turning a change-over valve 18 by means of a controller 14. In this system, after the flow rate and pressure of air and a sample gas respectively are regulated with flowmeters 3 and pressure regulators 4, the air is mixed with the sample gas at a ratio less than that of detonating gas, this mixture is adjusted to a certain temperature by means of the heating means 12, and the concentration of the odorant is determined with the odor sensor 13.

摘要： PROBLEM TO BE SOLVED: To provide an optical transceiver module which is easily detached from and attached to a cage. SOLUTION: The optical transceiver module is easily detached from and attached to a cage. The optical transceiver module includes: a housing which houses a photoelectric conversion element and a guide part formed along a cross direction; an operation lever which has an operation part and a lever side contact part and is mounted on the housing so as to be turned around a turning axis; and a slider which has wedge part for engaging with a locking part provided on the cage and a slider-side contact part for contacting with the lever-side contact part, and is guided in the cross direction by the guide part. The lever side contact part is located at the side opposite to the operation part when viewed from the turning axis, and when the operation part is pushed backward, the lever-side contact part pushes the slider-side contact part frontward, thus the slider moves frontward to a position at which the wedge part is detached from the locking part.

摘要： PROBLEM TO BE SOLVED: To prevent generation of tracking in the vicinity of the connecting section of a lead wire at a cylindrical high-voltage cut-out. SOLUTION: A protective cover 21, made of an insulating material, comprises a lead wire fitting part 22 which has an inserting hole 22a brought into close contact with an outer periphery of a lead wire 3, a stress cone fitting part 23 which has a cone-shaped hole 23a brought into close contact with an outer periphery of a stress cone 16, and an umbrella part 24 which covers part of a cut-out body 17 of the cylindrical high-voltage cut-out, and is formed into a rough funnel shape. The protective cover 21 is attached to the vicinity of a lead wire connecting part 15 at the cylindrical high-voltage cut-out (outdoor on-pole distribution apparatus). Adhesion of salt, dust, smoke or the like to the outer periphery of the vicinity of the lead wire connecting part 15, rainwater, concentrated electric field can be prevented. Partial discharge on the surface of the lead wire connecting part can be restrained, prevent insulation degradation and erosion in the vicinity of the lead wire connecting part, thereby preventing generation of tracking and burnout accidents of the insulating material in the vicinity of the lead wire connecting part.
