Abstract: The object is directed toward obtaining a process for preparing a solvent-type acrylic pressure-sensitive adhesive which is able to increase a conversion at polymerization in the preparation of the solvent-type acrylic pressure-sensitive adhesive to thereby solve the problems of odors associated with residual monomers and of attachment of gels on reactor walls, and further to provide improved productivity and workability.In the preparation of the solvent-type acrylic pressure-sensitive adhesives, a monomer composition containing alkyl (meth)acrylate ester as its main component is subjected to solution polymerization under a closed condition at least in a latter stage of the polymerization reaction. In the polymerization, the solution to be polymerized is maintained at temperatures not lower than a boiling point thereof under normal pressures or at 50.degree.-120.degree. C.

Abstract: A composition containing thermoplastic elastomer and elastic fine particles is extruded into a sheet-like shape from an extruder. Then, by expanding this sheet-like shape member, a covering sheet having minute unevenness attributable to the elastic fine particles formed on the surface is produced. The covering sheet may have an adhesive layer, a substrate layer, a foamed resin layer, etc., on the opposite side to the surface having a matt feeling. Such covering sheet can be produced with good productivity without creating environmental problems such as a problem related to solvent, etc. By molding using the covering sheet, a molding having matt feeling can be obtained.

Abstract: Pipelines are lined by inserting a lining pipe R out of a long profile beltlike member to be supplied and wound involutely within the pipeline. A jointing mechanism and a guide roller block are arranged around a mounting frame. The lining pipe R is produced while it rotates on its axis in response to rotary drive by the jointing roller block. An additional lining pipe is formed out of a belt like member to be supplied anew and ahead of the already formed pipe, which is left behind. A rigid mounting frame enables lining pipes of a specific diameter to be formed. Also, a flexible mounting frame helps to cope with a pipeline which is rectangular in cross-section. In addition, the already formed lining pipe can be large in diameter by feeding the belt like member at a higher level than the jointing mechanism which is traveling and sliding the joints of adjoining portions of the already formed beltlike member.

Abstract: A vacuum control valve controls the removal of sewage or other liquid removed from a tank by a vacuum discharge pipe. The control valve uses the amount of liquid in the tank, the atmospheric pressure, and the vacuum pressure of the vacuum discharge pipe to open or close a pipe communicating section which attaches the vacuum discharge pipe to a suction pipe disposed within the tank. When the pipe communicating section is opened, the liquid is removed from the tank via the suction pipe and the vacuum discharge pipe. When the tank is emptied, a damping diaphragm allows for decompression of pressure around its peripheral portion to prevent excessive suction. An opening time adjusting valve automatically self-adjusts to control the time period for a single suction activity based on the vacuum pressure inside the vacuum discharge pipe.
