Abstract: A rotation transmission buffer apparatus for transmitting the turning force of an input rotary body to an output rotary body through an elastic body provided therebetween. The input rotary body is provided with a plurality of engaging spaces, and the elastic body is provided with a plurality of engaging grooves and a plurality of projecting portions which are respectively fitted into the plurality of engaging spaces of the input rotary body. The output rotary body is provided with a plurality of protruding pieces which are respectively fitted into the plurality of engaging grooves of the elastic body.

Abstract: An anti-fogging film consisting essentially of a thin film of a transparent synthetic resin, which has micro concavities of at most 20 .mu.m in width and at most 10 .mu.m in depth formed over the entire surface of at least one side of the thin film, the total area of the micro concavities being from 20 to 80% of the area of the film surface on which the concavities are formed.

Abstract: A process for continuously producing epichlorohydrin which comprises reacting chlorine and allyl chloride in an aqueous medium, neutralizing and saponifying the resulting hydrochloric acid-acidified solution containing glycerol dichlorohydrin with an alkali to form a solution containing epichlorohydrin, and separating epichlorohydrin from the resulting solution; wherein(1) the neutralization and saponification are performed in separately provided neutralization and saponification zones,(2) a slurry containing mainly calcium carbonate and calcium hydroxide is separated from the residual slurry left after the separation of epichlorohydrin, and(3) the neutralization and saponification reactions are carried out while recycling the separated slurry containing calcium carbonate and calcium hydroxide into the neutralization zone.
