Patent number: 5269993Abstract: Whiskers having a diameter of 0.1-10 .mu.m and a length of 5-200 .mu.m are pelletized and granulated into agglomerates which have a size of 0.1-10 mm and a bulk density of 0.2-1.0 kg/liter.To pelletize, powders of whiskers are moistened with water while mixing to form primary aggregates. Then, the powders and the primary aggregates are subjected to a rolling movement to cause the primary aggregates to grow into secondary aggregates having desired size distribution. Finally, the secondary aggregates are dried to obtain pelletized or granulated agglomerates of whiskers.Handling of whiskers is facilitated because the agglomerates are less bulky and less likely to fly up in the air. When blended into molding materials for fiber reinforcement, however, the agglomerates are readily disintegrated back into separated individual fibers to provide homogeneous dispersion.Type: GrantFiled: October 29, 1992Date of Patent: December 14, 1993Assignee: Kawasaki Mining Co.

Patent number: 5199803Abstract: A character compression-decompression method for printers in which dots are added before compression of a character so as to generate a character in which the same dot pattern continues. The character is compressed and then is stored in a character geernator. Upon printing the character, the compressed character is read from the character generator and is then expanded so as to return the compressed character to the character before compression. The dots added when the character was compressed are removed from the expanded character. Thus, a character which cannot be compressed because the same pattern does not continue therein can be compressed by a simple compression method, and a large number of dot matrix characters can be stored in the character generator.Type: GrantFiled: March 21, 1991Date of Patent: April 6, 1993Assignee: Oki Electric Industry Co., Ltd.Inventors: Tadao Shimizu, Toshikazu Itoh

Patent number: 5002414Abstract: A method of automatically inserting a printing paper in a hopper of an automatic paper feeder or a manual insertion printing paper inserted from a manual paper input slot. Upon receiving an instruction to insert a printing paper by a printer, a platen is first rotated. Thereupon, provided the presence of the printing paper is detected by a sensor even with the platen being rotated by a prescribed amount, a paper feed motor of the automatic paper feeder is rotated for obtaining a printing paper from the hopper. While, provided the presence of a printing paper is detected before the platen is rotated by the prescribed amount, the paper feed motor is not rotated, it being assumed that the manual insertion of a printing paper has been already performed. After detected the presence of the printing paper, the platen is rotated by a prescribed amount to cause the printing paper to be moved to a position where a first line of the printing paper faces the face of the printing head.Type: GrantFiled: May 14, 1986Date of Patent: March 26, 1991Assignee: Oki Electric Industrial Co., Ltd.Inventors: Hiroshi Kikuchi, Jiro Tanuma, Tadao Shimizu, Akira Nagumo, Shinichi Katakura
