摘要： An outer surface of an object 23 is irradiated with visible light from a light source 21, and the reflected light is acquired by a TV camera 24. A two-dimensional image with gradation is Fourier transformed by an image analyzer 20. The brightness and darkness of the image are bipolarized using an emphasis coefficient in a predetermined wavelength range in the process of Fourier transform. The bright regions and dark regions forming closed regions are calculated separately as regions representing gloss irregularity or printing unevenness, thereby outputting a statistical parameter of the areas as a measured result.

摘要： In order to increase the performance of a mold of thermosetting resin, metal powder is dispersed in the resin mold which has a dense and voidless structure. The mold may be mounted on a back-up member of metal. In this case, the bonding between the mold and the back-up member is much assured when metal balls are contained in the mold near the back-up member. Furthermore, the mold may be electrically metal-plated. In this case, the mold is coated with a conductive plastic paint before being subjected to the electric metal plating in an electrolytic solution.

摘要： There is provided a novel polymaleimide compound represent by the formula (a) ##STR1## The present polymaleimide compound has a curability comparable to that of an epoxy resin. In addition, it is noted that a cured product prepared from the present polymaleimide compound is excellent in heat resistance and adhesion property and has a low linear expansion coefficient as compared with an epoxy resin. The above-mentioned excellent characteristics of the present polymaleimide compound are never observed with respect to conventional maleimide resins. There is also provided specific compositions containing the present polymaleimide compound for exerting the excellent effects of the present polymaleimide compound most effectively.
