An inflatable bladder is defined by two superimposed outer sheets of heat-sealable synthetic plastic fused together about their peripheral edges. An Intermediate layer or baffle is disposed between the two outer sheets and is alternately sealed to one and the other of the outer sheets to form air cells on the opposite sides of the intermediate layer. Each of the air cells is defined by an opposed ...

Moisture-curable melt-processible adhesives are obtained by reacting certain ethylene copolymers containing an alkyl acrylate and a carefully limited amount of a carboxylic acid with a stoichiometric amount of an epoxy-silane. A process of preparing the moisture-curable melt-processible adhesives in the absence of solvent is also available.

An optical inspection system inspects individual sheets having scrolled and unscrolled edges for defects in a production line with high transfer velocities. Each of the individual sheets are delivered in a production line with some spacing between them and potentially with some degree of skewness and offset from the production center line. The inspection system of the present invention utilizes a ...

PURPOSE:To stabilize temp. and to improve the controllability and reproducibility of ion exchange depth by immersing a substrate in a soln. at a temp. close to the b.p. of the soln. under constant vapor pressure and carrying out ion exchange. CONSTITUTION:The region of a substrate 1 not to be subjected to ion exchange is coated with a film 2 of a metal, oxide, nitride, etc., and the substrate 1 is...

PROBLEM TO BE SOLVED: To provide a liquid crystal optical element and its manufacturing method whose driving voltage is low and whose color purity is high. SOLUTION: An incident light 8 is made incident on a transparent substrate 1 from the upper side. Since the refractive index of high polymer material 5 is set to the ordinary ray refractive index of liquid crystal material or a value apploximate...
