IPC: H01J9/14
Filed: 1993-03-12
Abstract: PURPOSE:To provide a good paint film which is free from defective paint film caused by brittleness, and heat resistance and insufficient adhesion by painting an aqueous type erosion proof paint composition for shadow mask, for which a water soluble type resin and water dispersive type resin are used, on a base material. CONSTITUTION:An aqueous type erosion proof paint composition for shadow mask, for which a water soluble resin and a water dispersive type resin are used, is painted on a base material. For the water soluble type resin, for which sufficient protective function against an etching liquid which is strong acid, is required, it is preferred that water soluble property is provided by introducing an anion hydrophilic group such as carboxyl group phosphate group, or sulfonic acid group. For the water dispersive type resin, which is required to be stably dispersed in the paint, a resin which does no cause cohesion or precipitation when mixed with the water soluble resin, and which has good compatibility with the water soluble type resin, is preferred. For these types of resin, acrylic resin is preferred. The mixing ratio for the two kinds of resins is expressed as follows. Water soluble type resin/water dispersive type resin=20wt.parts/80wt. parts to 80wt. parts/20wt. parts.

Title: Method for direct treatment of chelating resin for wash wastewater
Inventor: MATSUMOTO TATAE
IPC: C02F1/62
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To remove radioactive substances such as uranium simply and to control the generation of sludge by removing suspended solids by filtering wastewater and passing the filtrate through a chelating resin. SOLUTION: Wash wastewater containing organic substances is filtered to remove suspended solids. The filtrate is passed through a chelating resin to do chelating resin treatment. The organic substances such as a detergent do not affect the adsorption of the chelating resin as shown by experimental results. Uranium and others adsorbed on the resin are eluted, and the resin can be reused. But, since only an extremely minute amount of radioactive substances such as uranium are contained in the wash wastewater, when the life of the resin is long, the resin is advantageously incinerated after being used for a long period to reduce the amount of waste. In this way uranium and others can be removed with a process simplified remarkably.

Title: Apparatus for measuring concentration of halogen in excimer laser medium
Inventor: HARUTA TAKEO
IPC: G01N27/18
Filed: 1985-03-18
Abstract: PURPOSE:To conserve the consumption of a medium, by employing a bridge circuit using heat resistors to introduce a laser medium to a measuring cell or do the laser medium cleared of halogen to a reference cell respectively. CONSTITUTION:Heat sensitive resistances 3 and 4 are arranged into a measuring cell 5 and a reference cell 6 respectively and current is fed from a power source 15 to heat the resistances 3 and 4. When media are introduced to the cells 5 and 6, heat of the resistances 3 and 4 flows to the cells 5 and 6 with the heat conduction of the medium introduced to reduce the electric resistance with a drop in the temperature of the resistances 3 and 4. So, a bridge circuit is built up with resistances 1 and 2 and the resistances 3 and 4 and when media of the same composition exist in the cell 5 and the cell 6, the resistances 1-4 are selected to balance the bridge. When a laser medium is introduced into the cell 5 while the laser medium cleared of halogen alone is done into the cell 6, the temperatures of the resistances 3 and 4 give different values from the difference of heat conductivity based on the presence of the halogen thereby enabling the measurement of the concentration of halogen from the difference in the unbalanced potential difference between the points A and B.
