A coater blade and backing roll combination contains a coater blade having an elastic steel blade with a wear-resistant coating formed thereon. The wear-resistant coating has a hardness greater than that of the elastic steel blade and is provided on an edge of the blade to define a coater surface for contacting with a moving surface of coated paper on the backing roll. The backing roll has a concave outer surface having a curvature corresponding to a quadratic equation and the coater surface has a concave curvature corresponding to the quadratic equation.

A roll used for tensioning a canvas belt used to hold paper against a dryer. The roll includes a main cylindrical body formed of steel. A layer formed of a metal harder than steel is disposed over the outer surface of the main body. The metal layer is formed with a channel around its center so as to define two spaced roll end sections of a common diameter. A fluororesin layer is disposed in the metal layer channel and is shaped so as to have an outer surface of a diameter equal to that of the metal layer end sections.

摘要:
A material strength measuring and evaluating method for measuring and evaluating of at least one of a peel strength and a fragility breaking strength of a fragile thin film. The method includes pressing an indenter into a test object and measuring an indentation load and an indentation depth, while at the same time detecting charged particles emitted from a peel starting point or a breakage starting point, specifying a peel occurring time and a fragility breaking time when charged particles are increased, and measuring the at least one of peel strength and the fragility breaking strength.

摘要:
A method of producing 2-fluorocyclopropane-1-carboxylic acid ester, which comprise by allowing a compound represented by the following formula (1): wherein X represents a chlorine atom, a bromine atom or an iodine atom; and R1 represents an alkyl group having 1 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, or an aralkyl group composed of an aryl group having 6 to 12 carbon atoms and an alkylene group having 1 to 6 carbon atoms; to react with a reducing agent in the presence of a phase transfer catalyst. According to the production method of the present invention, the reaction time of dehalogenation can be greatly shortened.
