摘要： Apparatus and method for testing surface defect on an object are disclosed, which comprise an illumination means for illuminating collimated lights onto a surface of the object obliquely to the surface and from two symmetrical directions, a sensor composed of a TV camera or a linear image sensor for sensing diffused reflected lights from the surface of the object in the direction perpendicular to the surface, a classification means for discriminating the sensed image signal by a threshold level which is higher than an average level of the image signal and a threshold level which is lower than the average level to determine the surface defect pattern as a broken cavity pattern or a pit or crack pattern by the discriminated signals, and a discrimination means for calculating L.sup.2 -4.pi.S, where S is an area of the defect and L is a length of the contour, when signal discriminated by the lower threshold level is produced to discriminate the pit pattern and the crack pattern by determining whether L.sup.2 -4.pi.S exceeds a predetermined value or not. In this manner, the defects that exist on the surface of the object can be classified and evaluated.

摘要： An anisotropic aromatic polyamide dope comprising more than 10% by weight of an aromatic polyamide and a solvent for the polyamide, said polyamide consisting essentially of, at least 5 mole% but less than 35 moles%, based on its entire units, of an only partially p-oriented structural unit expressed by the following formula ##STR1## wherein Ar.sup.1 is a divalent aromatic ring whose chain-extending bonds are coaxial or parallel, X is a member selected from the group consisting of O, S and NH, and the NH group bonded to the benzene ring of the above benzoxazole, benzothiazole or benzimidazole ring is meta or para to the carbon atom of said benzene ring.
