Title: Method of after-treating fatty alcohol solution of alkylpolyglycoside by distillation
Inventor: YURUGEN GURIYUTSUTSUKE
IPC: C07B63/00
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To after-treat the subject solution by distillation without applying heat load by distilling a fatty alcohol solution of an alkylpolyglycoside to separate a low-boiling component, separating taken out fatty alcohol from a low- boiling component in a fractionating column and after-treating the subject solution by distillation without applying heat load.  
     SOLUTION: A fatty alcohol (e.g. long chain alcohol) of an alkylpolyglycoside is distilled at 100-150°C under 15-50 mm bar pressure to separate low-boiling component such as water or butanol and a fatty alcohol taken out in this time is removed from the low-boiling component vapor in a fractionating column. Thereby, a fatty alcohol solution of an alkylpolyglycoside which is a nontoxic and readily decomposable surfactant and useful as a detergent and cleaning agent and as a emulsifying agent and a dispersing agent is after-treated and purified.

Filed: 1987-12-16
Abstract: PURPOSE:To manufacture perfluoroalkylvinyl ether modified tetrafluoroethylene resin mold with high accuracy in size by baking a preparatorily-molded object at temperature not less than the melting point thereof while said object is kept not in face contact with a metal, thereby to control imbalanced shrinkage of said object at the baking time. CONSTITUTION:Perfluoroalkylvinyl ether modified tetrafluoroethylene resin mold is manufactured by baking a preparatorily-molded object at temperatures not less than the melting temperature thereof in the state that the object is not in face contact with a metal. The amount of perfluoroalkylvinyl ether (PFVE) in the perfluoroalkylvinyl ether modified tetrafluoroethylene resin is generally 0.005-1wt.%. In the case where the amount of the PFVE is less than 0.005wt.%, the resistance to creep is not effectively improved. Even when the amount of the PFVE exceeds 1wt.%, improvement in the resistance to creep is not observed in spite of the increased amount of expensive PFVE, which is drawback from an economical viewpoint. The baking temperature is adequate at 340-390 deg.C which is a standard for baking this resin.

Abstract: PROBLEM TO BE SOLVED: To keep resonance frequency constant regardless of the magnitude of input energy by improving a spring body supporting a trough in an electromagnetic feeder vibrating the trough to feed an article via intermittent excitation to an electromagnet. SOLUTION: A spring body is constituted of multiple plate spring members 21 and spacer members 22 provided between the plate spring members 21 at the upper and lower end sections, and edge sections (a) at the end edges of the spacer members 22 on the contact faces with the plate spring members 21 on the center side of the plate spring members 21 are formed into a curved face shape. As the plate spring members 21 are bent, the effective size of their elastic sections is decreased, and the resonance frequency is increased, thereby a phenomenon that the resonance frequency is decreased as input energy is increased can be offset by the sliding friction on the contact faces between the plate spring members 21 and the spacer members 22.
