Title: Method for making porous membrane of polyolefin hydrophilic
Inventor: ITO HAJIME
IPC: D06M101/16
Filed: 1985-10-23
Abstract: PURPOSE:To make a membrane hydrophilic as far as internal surfaces of pores without lowering the strength of the membrane, by treating a polyolefin membrane in a solution of a substance which abstracts hydrogen from polyolefin by means of irradiation of ultraviolet rays, applying ultraviolet rays to said membrane, bringing said membrane thereafter into contact with oxygen. CONSTITUTION:As a substance to abstract hydrogen by means of irradiation of ultraviolet rays, an initiator for polymerization for use in photopolymerization is employed. Particularly, compounds of benzophenone are preferable. A sub stance for abstracting hydrogen is dissolved in an organic solvent having good wettability for porous membrane of polyolefin and a porous membrane of polyolefin is dipped therein. Preferable concentration of solution is 0.01-5wt%. Ultraviolet rays are applied to this porous membrane in an atmosphere having practically no oxygen and then said membrane is placed in an oxygen present atmosphere, i.e., in the air etc. For irradiating ultraviolet rays, a mercury lamp, a xenon lamp, etc., are used with an irradiation of 0.001-10joule/cm<2>. In such a manner, a porous membrane of polyolefin is partially oxidized, thereby such part is made hydrophilic.

Title: Waterproof sheet for tunnel and fixing structure thereof
Inventor: KITAGAMI HIDEO
IPC: E21D11/38
Filed: 1990-09-10
Abstract: PURPOSE:To prevent breakage of a waterproof sheet due to contact of it with an anchoring tool by anchoring the waterproof sheet, to the back of which a cushioning material is laminated, to a natural ground through a fin for fixing. CONSTITUTION:A back cushioning material 2 formed of non-woven cloth is laminated to a water-barrier sheet body 1, e.g. rubber, and a weld margin 4 is formed to the outside to form a waterproof sheet 10. Fins 6 for fixing in a shape having a containing space for a concrete pin 7 are locked to the end parts on both sides of the cushioning material 2. The cushioning material 2 of the sheet 10 is brought into contact with the wall surface of sprayed concrete 5, and the pin 7 is driven in the concrete 5 through the fin 6 to secure the pin. Similarly, after an adjoining waterproof sheet is fixed, weld margins 4 are welded and joined with each other. Since even when the placing pressure of lining concrete is applied, the pin does not make contact with the sheet body, this constitution prevents breakage of the sheet body and reliably prevents leakage of water.

Title: Testing method of optical branch path
Inventor: KUWABARA TSUNEO
IPC: H04B10/07
Filed: 1990-09-07
Abstract: PURPOSE:To measure without lowering the transmission characteristic and the dynamic range by a method wherein a plurality of testing photosignals of different wavelengths are divided for every wavelength, and supplied to different branching optical fibers with use of a transmission optical fiber different from a main optical fiber. CONSTITUTION:Testing photosignals H1-H3 from an optical pulse tester 1a are transmitted though a transmission optical fiber 11 to an optical filter 12. The photosignals are divided into photosignals H1, H2, H3. The photosignal H1 is supplied to a branching optical fiber 4-1 via an optical fiber wiring FB1 and an optical multiplexer/demultiplexer 13-1. Similarly, the photosignals H2, H3 are respectively supplied to fibers 4-2, 3. A transmission photosignal S is guided to each optical fiber 4 from a transmission device 10. Although backward scattering lights are generated by the photosignals H1-H3 and S, only the backward scattering lights B1-B3 of the former signals are detected by the tester 1a, whereby the transmission characteristic of the optical fiber 4 is measured. Accordingly, it is possible to measure the transmission characteristic of the optical fiber 4 without attenuating the photosignals H1-H3 and holding the good dynamic range.
