Title: Adjusting method for optical transmitting line
Inventor: KATOU TOMIO
IPC: H04B10/293
Filed: 1981-05-19
Abstract: PURPOSE:To simplify the adjustment of optical signal transmitting level by transmitting an optical signal for adjustment from the transmitting side, returning the decided result of the transmitted signal level from the receiving side to the transmitting side and adjusting the optical signal level in the transmitting side on the basis of the returned result. CONSTITUTION:An adjusting signal is sent from a transmitting data input terminal 14 of a transmitter 8 to an optical fiber transmitting line 24 through an electricity-light converter 10. In a receiver 9, the adjusting signal is applied to a detecting circuit 18 through light-electricity converter 17. The detecting circuit 18 decides whether the received optical signal level is proper or not and sends the decided result to a light-electricity converter 15 of the transmitter 8 through an electricity-light converter 22 and a transmitting line 25. The decided result of the receiver is displayed on a display device 12 by the output of the coverter 15. An optical signal level of the electricity-light converter 10 is adjusted by operating an adjusting circuit 11 on the basis of the displayed result, simplifying the adjustment of the tramsmitting level.

Abstract: PURPOSE:To recover and discharge slime remaining in a hole bottom for a cast- in-place pile, by a method wherein, after a hollow cylinder body, provided at the lower part with an impeller, is secured to the hole bottom, the impeller, having plural fan-shaped blades with a front edge slanted downward, is rotated. CONSTITUTION:After a hole 24 for a cast-in-place pile is excavated, slime 26 in a hole bottom is removed such that a hollow cylinder body 1 is hung down into the hole 24 by means of a rope 18, a bit 2 is forced to burrow into a slime layer or a ground, and the rotation of the hollow cylinder body 1 is stopped. With a submerged motor 13 driven under the above condition, an impeller W is rotated in a direction C through a central shaft 4. Since a front edge part 3a of each of fan-shaped blades 3 of the impeller W is slanted downward, the slime 26 tries to move in a direction D, the rear edge side of the blade 3 is displaced upward, and the slime 26 is taken in the hollow cylinder body 1 above the slime. Thereafter, by lifting up the hollow cylinder body 1 to the outside of the hole 24, the slime 26 is discharged.

Title: Manufacture of thermoplastic composite material
Inventor: NAKAGAWA MASARU
IPC: B29B15/12
Filed: 1992-02-27
Abstract: PURPOSE:To contrive to improve the impregnability of thermoplastic resin to continuous reinforcing fiber and production speed by a method wherein the impregnation of molten thermoplastic resin is carried out after the gas in fiber bundle is reduced by passing the continuous reinforcing fiber through a vacuum vessel. CONSTITUTION:Continuous reinforcing fiber 1 enters through a sealing part 2 for keeping vacuum in a vacuum vessel 3. The favorable vacuum attainable of a vacuum vessel 3 is about 0.01-300Torr. After the gas in fiber bundle is reduced in the vacuum vessel 3, the continuous reinforcing fiber enters through a sealing part 4 in a molten resin chamber 5 so as to be impregnated with resin and is finally pulled outside through a resin sealing part 6. As sealing method, the passing through a slit part, the cross-sectional area of which is slightly larger than that of the reinforcing fiber 1, is favorable. Thus, wire having high degree of impregnation of resin or the like can be obtained at high production speed.

Title: Oxygen concentration measuring instrument
Inventor: YOSHIOKA TAKEO
IPC: G01N27/404
Filed: 1993-04-02
Abstract: PURPOSE:To enable an oxygen concentration measuring instrument to stably operate for a long period in a low-humidity, high-temperature environment and, at the same time, to increase the degree of freedom in design of an electric device for fitting an oxygen concentration measuring instrument by positioning either one of a negative and positive electrodes along the internal surface of an electrolyte container. CONSTITUTION:When the title measuring instrument is installed in a low-humidity, high-temperature environment, for example, in an outdoor SF6-gas enclosed electric device, an electrolyte 4 evaporates through an FEP membrane 8 and bubbles in an AB-made container 11 grow. As a result, an expanded gas phase 13 interrupts measurement. When, however, a negative electrode 12 is formed on the internal surface of the container 11 so as to surround the electrolyte 4 in the container 11, normal and stable measurement can be performed, since the electrolyte 4 exists between the negative electrode 12 and a positive electrode 13 for a long period. Since such an effect can be obtained irrespective of the type of the container 11, whether a vertical type (the positive electrode 3 is on the down side) or horizontal type (the electrode 3 is on the lateral side), the degree of freedom of electric device for fitting the measuring instrument can be increased.
