Title: Production of cellulose triacetate film
Inventor: TAKEDA AKIRA
IPC: B29C41/12
Filed: 1990-04-19
Abstract: PURPOSE:To improve the tear strength and bending resistance of film by a method wherein the film is dried in such a condition as to give a specific relationship between a volatile portion of the film and the film surface temperature. CONSTITUTION:The subject production method comprises a casting process of stretching on a supporting body having its surface temperature maintained at not higher than 10 deg.C a dope wherein the concentration based on the sum of the weights of cellulose triacetate and other component to be hardened after drying is 18-35wt.% and the ratio of the solvents other than methylene chloride in the solvent composition is 13-25wt.% and a drying process of removing the cast film from the supporting body and drying the same. Given that a volatile portion of the film is X (%) and the film surface temperature is Y ( deg.C), the film is dried in a condition within a range of the expressions indicating relation- ship between X and Y. This film production method permits the crystallization of cellulose triacetate to be controlled in the drying process and improves tear strength and bending resistance of the film.

Abstract: PURPOSE: To permit the regeneration of filter by combustion in order to keep the effective function of the filter for a long period of time by bringing a copper compound into contact with carbon particles present in exhaust gas being collected on the heat-resistant filter.  
     CONSTITUTION: Fine particles present in exhaust gas are collected by a heat- resistant filter 4, and when the filter 4 is blocked to a given extent, an aqueous solution of a copper compound, e.g., CuCl, CuCl 2 , Cu(OH) 2 , etc., is jetted from a supplier 5 so as to bring it into contact with the collected fine particles, whereupon the fine particles takes fire and are burned because the heat-resistant filter 4 is heated by waste heat. In this case, the temperature of ignition is lowered and the burning speed is accelerated by the action of the copper compound. The copper  compound used may be powdery and may be supported on the heat-resistant filter  which may have a ceramic honeycomb structure.

Title: High tensile brass
Inventor: KAWAKATSU ICHIROU
IPC: C22C9/00
Filed: 1981-07-04
Abstract: PURPOSE:To improve the strength of brass without deteriorating the workability such as rollability or drawability by simultaneously adding small amounts of Ti and Sn to brass. CONSTITUTION:High tensile brass consisting of 0.05-1.0% Ti, 0.05-1.5% Sn, 55-80% Cu and the balance Zn is an economical Cu alloy having fvaorable mechanical properties, especially workability, high strength and high elasticity and substitutable for phosphor bronze for a spring in a degree. By simultaneously adding Ti and Sn to brass, the tensile strength is increased while reducing the amount of added Ti, and high elasticity is obtd. As the amount of added Ti is increased, oxidation proceeds violently during melting to increases the oxide content of the molten metal, the workability and electric conductivity are reduced, and the cost is increased. Accordingly, the Ti and Sn contents are restricted to <=1.0% Ti and <=1.5% Sn, and since <0.05% Ti and <0.05% S are not well effective in increasing the strength, >=0.05% Ti and >=0.05% Sn are required.

Title: Oxygen intercepting film forming material and oxygen intercepting film
Inventor: YAMAGUCHI SHINYA
IPC: G02B5/20
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a pattern image having satisfactory resolution by incorporating a water-soluble polymer having oxygen intercepting ability and a specified amt. of a plasticizer. SOLUTION: The oxygen intercepting film forming material contains a water- soluble polymer having oxygen intercepting ability and 1-25 wt.% plasticizer based on the solid weight of the film forming material. A polymer having low oxygen permeability, transmitting radiation for exposure and soluble in water or an aq. soln. can be used as the water-soluble polymer and an alginate or methylcellulose is, e.g. used. The plasticizer plasticizes a formed oxygen intercepting film and makes the film deformable in accordance with the hardening shrinkage of a photosensitive layer. Preferably the plasticizer has good compatibility with the water-soluble polymer and does not reduce the oxygen intercepting ability and light transmittance. Ethylene glycol, propylene glycol or trimethyl glycol is, e.g. used as the plasticizer.  The objective oxygen intercepting film is formed by applying and drying the oxygen intercepting film forming material.
