Abstract: An identification level control method and an optical receiver are disclosed to determine an optimal identification level in a simple structure without clock extraction. In the identification level control method, an identification level supplied to a limiter amplifier is changed from a lower bound to an upper bound thereof and is stored together with an output average of the limiter amplifier. Then, a first average and a second average are set based on the output average. A first identification level corresponding to the first average and a second identification level corresponding to the second average are obtained, and an optimal identification level is computed based on the first identification level and the second identification level, and is supplied to the limiter amplifier.

Abstract: A highly fashionable finger ring consisted of replaceable ring-shaped members is provided. A finger ring has ring-shaped members 1 and 2, each ring-shaped member 1 and 2 being decoupled in the center part, and between the both ends of a circular arc part 9(10), an opening 3(4) is produced by being twisted the both ends in a counter direction. Each end of the first ring-shaped member has the jewelry part 5 and 7 respectively, while each end of the second ring-shaped member having the jewelry part 6 and 8 respectively. The jewelry part 5(6) is relatively large, while the other jewelry part 7(8) being relatively small. Relatively large jewelry part 5(6) may be stereoscopic and large. When putting on a first and second ring-shaped member 1 and 2 in a manner opposed each other, a relatively large jewelry part 5(6) of either one of the two ring-shaped members fits in the opening 4(3) of the other ring-shaped member, seeming like one finger ring.

Abstract: A thermosetting adhesive film comprising a uniform adhesive matrix containing a thermosetting resin and a curing agent therefor, and a thermoplastic resin; and a filler material dispersed in the adhesive matrix, wherein the filler material comprises an inorganic material and a domain to incorporate the inorganic material, the domain consisting of an elastic polymer which is elongated and oriented in one direction substantially perpendicular to the thickness direction of the adhesive film. This adhesive film provides good properties of coefficient of thermal expansion and elastic modulus, without exhibiting reduced adhesive force which would be otherwise observed in association with the addition of large amounts of filler material.

Abstract: A coating device for carrying out a die coating method, which is capable of rapidly and assuredly eliminating an undesirable streak occurring in a coating layer during the coating operation. The coating device includes a coating head spaced from a back-up roll, and a shifting mechanism for shifting the coating head close to and remote from the back-up roll. The shifting mechanism includes a reciprocation carriage mounted onto a stationary frame to be linearly reciprocatedly movable thereon, a drive section for reciprocating the reciprocation carriage on the stationary frame, and a stop section for selectively hindering the linear motion of the reciprocation carriage caused by the drive section at a desired position. The shifting mechanism operates to instantaneously reciprocate the coating head at a small distance so that a distance between the outer surface of the back-up roll now carrying out the coating operation and the coating face of the coating head temporarily increases.
