Title: Wholly aromatic polyamide flat yarn, production thereof and brush made therefrom
Inventor: NOROTA SUSUMU
IPC: A46D1/00
Filed: 1986-07-01
Abstract: PURPOSE:To provide a flat aramid yarn composed mainly of a specific wholly aromatic polyamide, essentially free from aprotic polar solvent, having specific flatness and thickness of the flat cross-section, large diameter and high resistance to bending and suitable for the production of a heat-resistant brush. CONSTITUTION:A wholly aromatic polyamide containing m-phenylene isophthalamide unit as >=85mol% of the whole units is subjected to interfacial polymerization to obtain powder of porous agglomerated particles. The powder is compression-molded to obtain a plate 10 having a void ratio of <=5%. The plate is introduced into a preheating zone 40, in which it is vertically transferred and preheated at a temperature lower than Tg+20 deg.C (Tg is glass transition temperature of the polymer). The preheated polymer is passed through a nozzle 60 having a flatness of >=1.5. A wholly aromatic polyester flat yarn essentially free from aprotic polar solvent and having a flatness of >=1.5 and a minor diameter of the cross-section of 0.03-3mm can be produced by this process.

Title: Method for annealing coil of al foil
Inventor: NAKADA KAZUHIRO
IPC: C22F1/04
Filed: 1985-07-11
Abstract: PURPOSE:To prevent the adhesion of coiled Al foil in an annealing stage and to efficiently remove oil sticking to the surface of the foil by specifying the heating rate of the coil of Al foil, conditions during holding at the annealing temp. and the cooling rate after annealing. CONSTITUTION:A coil of Al foil is heated to the annealing temp. at <=70 deg.C/hr heating rate. At this time, heating capacity Q ( deg.C.hr) in the temp. range of >=200 deg.C is set so as to satisfy conditions represented by the formula [where W is the width (mm) of the coil]. After annealing is finished, the coil is cooled at <=60 deg.C/hr cooling rate. By this method, the adhesion of the coiled Al foil can be prevented in the annealing stage without leaving oil on the surface of the foil in excess. Accordingly, hygienic Al foil having a satisfactory adhesive property to a PE film or the like and free from defects such as distortion can be manufactured.

Title: Method for inspecting material used in photosensitive material coating solution and method for inspecting characteristics of the coating solution
Inventor: IWASAKI HIROAKI
IPC: G03G5/05
Filed: 1989-06-15
Abstract: PURPOSE:To simply discriminate the quality of a material to be used or photosensitive material coating solution within a short time by discriminating the dispersion state of the coating solution by a thin layer chromatographic test method. CONSTITUTION:A thin layer chromatographic test method is applied to a coating solution in the inspection of the pigment dispersion state of the coating solution 1. That is, the coating solution 1 is received in a container 2 and the lower end part of a thin layer chromatographic test piece 3 is immersed in the coating solution to be allowed to stand for a predetermined time(min) and the development state of the coating solution 1 is observed while the development distance thereof is measured to discriminate the dispersion state of the material contained in the coating solution 1. When there is only the development of the coating solution and the development only of a solvent is not almost generated or when the development only of the solvent is little, the material dispersion state of the coating solution 1 is good and the coating solution is usable and the pigment dispersion state of the coating solution 1 is bad as the development distance 3c only of the solvent becomes large and the photosensitive characteristic of a photosensitive material becomes inferior as the dispersion state becomes bad and the coating solution becomes unusable at last. By this method, the quality of the photosensitive material coating solution can be simply discriminated.

Title: Method of liquid phase epitaxial growth
Inventor: SUZUKI TOSHIHIRO
IPC: H01L21/208
Filed: 1980-10-31
Abstract: PURPOSE:To elongate the life of melt and to enhance the yield rate of the growth of a thin film by growing the crystal only on the surface of a substrate on which excellent thin films can be grown. CONSTITUTION:A holding body 26 which holds the substrate 4 comprises equally spaced four arms 23. The upper ends of the arms 23 are linked to a ring 27 which is in turn connected to a holding rod 25. At the lower ends thereof, pawls bent in a shape of L are provided to hold the substrate 4. At the tip of the pawls, blades 28 which operate as a screw in order to move melt 2 upward when the arms 23 are rotated are protruded inward. When the supporting rod 25 is lowered, the arms 23 are immersed in the melt 2 in a crucible 1. Since the specific gravity of the substrate 4 is smaller than that of the melt 2, the substrate 4 keeps the immersed state, and the crystal is grown only on the surface of the substrate 4. The melt 2 is churned in the direction of arrows by the blades 28, and the temperature of the melt 2 becomes uniform.

IPC: G06K9/34
Filed: 1991-06-25
Abstract: PURPOSE:To highly precisely segment a character from a general printing document including an unevenly distributed character. CONSTITUTION:A temporary termination detection means 16 detects a temporary segmentation termination position according to whether an estimated segmentation termination position apart from the segmentation start position of a character pattern by an estimated character pitch is positioned in a black block area or not. A block detection means 18 detects unevenly distributed character blocks from a temporary segmentation area based on the number of black blocks in the temporary segmentation area between the segmentation start position and the temporary segmentation termination position, and a position relation with adjacent black blocks. A termination decision means 20 decides the segmentation termination position based on the temporary termination position and the result of block detection. A segmentation means 22 segments the character pattern based on the segmentation start position and the segmentation termination position, and a pitch correction means 24 corrects the estimated character pitch and sets the next segmentation start position.
