Title: Hygroscopically swelling dry developer for infiltration flow detection and method for infiltration flaw test
Inventor: FUMIYA TADAYUKI
IPC: G01N21/91
Filed: 1986-03-25
Abstract: PURPOSE:To three-dimensionally enlarge a flaw indicating pattern and enable a defective portion to be detected by utilizing the nature that, when a white highly water- absorbent resin powder is brought into contact with water, the resin powder instantaneously absorbs water and swells. CONSTITUTION:White highly water-absorbent resin powder particulates with the particle size of 20mum or below and of the quantity corresponding to 5-95% by weight of white inorganic fine powder are blended with a dry type developer for an infiltration flaw that composed of the white inorganic fine powder with the particle size of 20mum or below. On the other hand, a water base dyed penetrant for the infiltration flaw test wherein water and a visible dye are blended is attached to the surface of an object to be inspected and, after the penetrant infiltrates the inside of a defective portion, the surplus penetrant remaining on the surface of the object to be tested is removed. Then, hygroscopically swelling dry type developer for the infiltration flaw test that is previously blended is brought into contact and draws out the penetrant infiltrating the inside of the defective portion. Part of the developer is attached to the periphery of the defective portion by the penetrant thus drawn out and the resin fine powder blended in the attached developer is made to hygroscopically swell, thereby a defect indicating pattern is formed.

Title: Rise and fall type weir made of elastic film
Inventor: TSUJI YOSHIOMI
IPC: E02B7/20
Filed: 1979-05-26
Abstract: PURPOSE: To prevent the freezing of water contained within a space made of elastic film by a method wherein an adiabatic material is attached to an elastic film forming a weir which rises and falls by the pouring-in and the discharge of water contained within the weir.  
     CONSTITUTION: A weir made of elastic film 1 is fixedly set on a river bed and the weir is raised by inflation by the pouring of water within the inside thereof being surrounded by the film, while the weir is fallen by the contraction of the weir from where water is discharged. Because an adiabatic material 5 is attached on the whole surface or a part of the film, the water 4 being contained therein does not freeze. As a result, inflation or contraction of the elastic film 1 by the pouring-in or discharge of the contained water is not interrupted by the freezing of water.
