Abstract: PURPOSE:To prevent a thermal head from being fused to base film during high energy recording by providing a heat-resistant layer obtained by curing compounds containing an acryl group or a metacryl group obtained due to specific reaction on the film surface of sheet for thermal transfer recording which has a color material layer to which data is thermally transferred. CONSTITUTION:A color material layer to which data is thermally transferred is provided on one surface of base film. And on the other surface, a heat-resistant layer is provided that is formed by curing a multiple functional glycidil amine compound containing an aromatic ring and a compound containing an acryl group or a methacryl group obtained by reaction with acrylic acid or methacrylic acid. The preferable multiple functional glycidil amine compounds containing an aromatic ring are tetraglycidilmetaxylene diamine and triglycidil-n-amine phenol, which contain more than three glycidil groups in terms of heat resistance. The preferable content ratio of one glycidil group and carboxydil groups in the glycidil amine compound is 1 to 0.5 to 1.3. To inhibit the polymerization of the acryl group or metacryl group when reaction takes place, it is desirable to use a known polymerization inhibitor such as hydroquinone or methyl hydroquinone. The reaction should take place with the stirring of chemicals at 40 to 160 deg.C in the presence or absence of a solvent.

IPC: G02B6/02
Filed: 1985-11-29
Abstract: PURPOSE:To obtain an optical multiplexer and demultiplexer whose accuracy is high and whose loss is small, by applying a torsion to a multicore fiber which has placed an outside peripheral part single mode core having a larger propagation constant that that of a center part single mode core, in the outside periphery of the center part single mode core, and setting a component difference in the longitudinal axial direction in the propagation constant to zero. CONSTITUTION:An arrangement of single mode cores 11, 12 is set so that one 11 and the other 12 are positioned in the center part, and its outside peripheral part, respectively. As for a propagation constant, when that of one core 11, and that of the other core 12 are denoted as beta1 and beta2, respectively, they are set as beta2>beta1. When a multicore fiber 10 is twisted, a component in the longitudinal axial direction of the propagation constant becomes beta1, and beta2costheta, in case of one core 11, and in case of the other core 12, respectively. Accordingly, by adjusting the torsion applied to the multicore fiber 10, beta2costheta=beta1 can be obtained, a component difference in the longitudinal axial direction of the propagation constant can be set to zero, and said fiber can be used as an optical multiplexer and demultiplexer.

Title: Cam shaft grinding attachment
Inventor: IMAI TOMOYASU
IPC: B24B19/12
Filed: 1984-12-19
Abstract: PURPOSE:To shorten a span of spark-out time, by constituting either of a master cam and a follower roller or both with such a material of 5,000-10,000kgf/mm<2> in a Young modulus excellent in damping capacity. CONSTITUTION:A master cam 19 is forcibly pressed to a follower roller 31 by a rock of a rocking block 18 by dint of spring force. And, this follower roller 31 consists of a material of 5,000-10,000kgf/mm<2> in a Young modulus excellent in damping capacity. When a grinding point shifts from a cam top part to a cam side part, a variation in acceleration of the rocking block 18 to be rocked by a cam lift difference grows large whereby the master cam 19 impulsively comes into contact with the follower roller 31, producing a vibration there, so that chattering marks come to be produced on a cam shaft grinding surface in consequence. However, this impact is absorbed and relieved owing to the roller 31 made of such a material as being excellent in damping capacity, and vibro-generation is prevented from occurring, thus spark-out time is shortened.

Filed: 1987-10-27
Abstract: PURPOSE:To accurately detect the surface state of a material to be inspected only with coarse adjustment, by receiving the regular reflected light from a first light source and the diffused reflected light from a second light source, and separating and processing the light beams into respective electric signals based on recognizing elements included in the light sources. CONSTITUTION:Light sources 10a and 10b are parallel, linear light sources. Their optical axes form angles theta and 90 deg. with respect to the surface of a material to be inspected 1. A filter 13a transmits a blue color. A filter 13b transmits the mixed colors of red and green. A light receiving part 20 is a color image sensor 21 of a photodetectors of three primary colors. The optical axis of the part 20 forms an angle theta with respect to the surface of the material to be inspected. Since the light from the light source 10a is diffused to some extent, the regular reflected light is received. Since the light source 10b is perpendicular to the surface to be inspected, the diffused reflected light is received. Therefore, coarse adjustment of the optical axes is enough. The obtained electric signals are amplified and judged in a judging part 33 through a color recongnizing part 32. The six surface states of green and red stains, flaws and the like can be accurately detected.
