Abstract: PURPOSE:To enable an electrode consumption rate to be held in an epoch- making low level, by using a water solution, in which the content of 0.5-85% alkoxyoxyethylene derivative as a water soluble compound is added as an essential component, for the machining fluid. CONSTITUTION:The electric discharge machining fluid uses a water solution such that water, after it is previously processed by ion exchange resin so as to obtain the specific resistance of about 10<4>OMEGA.cm or more, adds 0.5-85% alkoxyoxyethylene derivative as shown by a general formula (I) to be stirred and dissolved (where R1 is single or plural optional replacement radicals in alkyl group of carbon number 1-4, R2 is single or plural optional replacement radical in hydrogen methyl group, ethyl group and n is integer within a range of 4-100). If the water solution A, as described in the above, is used as the machining fluid, an electrode obtains not only a low consumption rate but also an excellent machining speed.

Title: Regeneration method of ion exchange resin
Inventor: SAITOU JIYUN
IPC: C07C239/00
Filed: 1980-06-10
Abstract: PURPOSE: To perform regeneration simply and enable repeated use by regenerating weakly acidic cation exchange resin used to separate guanidine carbonate from a process liquid of urea manufacture with caustic alkali under heating.  
     CONSTITUTION: In urea synthesis in which ammonia is made to react with carbon dioxide under high temperature and pressure, guanidine carbonate is separated and recovered from the process liquid using weakly acidic cation exchange resin. At this time, the resin lowered in capacity is treated with strong mineral acid or aqueous solution of caustic alkali such as ammonium carbonate heating at above 40°C. By this way, the ion exchange capacity of the resin can be restored remarkably, and this regeneration can be used repeatedly.

Namely, the developing roller 11 produced by forming an elastic layer 2 around a shaft 1 is dipped in dispersion liquid prepared by dispersing fine particles 3 in a solvent 4. The roller is drawn up and dried to uniformly distribute the fine particles on the roller surface. The drying conditions are controlled according to the kind and density of the fine particles in the dispersion liquid, and 70 to 110 deg.C and 2 to 6 hours for drying is preferable to completely remove the solvent 4 and to fix only the fine particles 3 on the developing roller 11. Thus, the developing roller 11 with which a high quality image can be formed can be completed.

Title: Monolithic refractory excellent in structural spalling resistance
Inventor: MIYAMOTO YOKO
IPC: C04B35/66
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To facilitate practical construction of monolithic refractory excellent in spalling resistance by specifying dependence of elastic modulus at ambient temperature on temperature in a prescribed monolithic refractory. SOLUTION: This monolithic refractory is obtained by using a refractory raw material selected from a group selected from alumina-based, alumina-spinel- based, alumina-magnesia-based, magnesia-based raw materials and a curing agent as main raw materials and kneading the material with water and executing the kneaded product. In the refractory, dependence of elastic modulus at ambient temperature on temperature is >=1,500kg/cm<2> . deg.C. Since a monolithic refractory is used without baking, densification and the change of mineral phase are produced during use and the gradient of physical property corresponding to temperature gradient from operating face to the rear face is formed and the gradient often causes structural spalling. Therefore, structural spalling resistance can be improved by controlling dependence of elastic modulus on temperature.  Refractory powder amount having <=10μm particle diameter and contained in the refractory raw material is set to <=15wt.%.
