Patent number: 5700867Abstract: An aqueous dispersion of an aqueous polyurethane having an ionic functional group, polyoxyethylene units and terminal hydrazine functional groups is provided. Content of the ionic functional group is about 5 to about 180 milliequivalent per 100 g of the aqueous polyurethane, and content of the polyoxyethylene unit is about 20% by weight or less of a weight of the aqueous polyurethane. The aqueous dispersion is used for a composition for ink, coating or adhesive. Storage stability, water resistance, pigment dispersibility, and adhesion to various kinds of substrates, particularly non-polar substrates, of the aqueous dispersion and the composition are excellent.Type: GrantFiled: April 29, 1996Date of Patent: December 23, 1997Assignee: Toyo Ink Manufacturing Co., Ltd.Inventors: Masaaki Ishiyama, Takeaki Matuura, Takashi Mihoya, Shinya Fujimatsu, Masayoshi Utsugi, Kouichi Iibuchi

Patent number: 4910610Abstract: Four channels of group 3 facsimile signal are transmitted through a digital transmission line of Bearer rate 64 Kbits/s for a speech signal. A facsimile signal is separated into a tone signal, a binary control signal, and a picture signal, each converted to digital form. Then, a block having 160 bits is assembled including 96 data bits and some control bits, and a justification bit. A justification bit matches clock rate of the present system with clock rate of an external digital transmission line by deleting or inserting one bit in a block. Thus, a conventional group 3 facsimile device is coupled with 16 Kbits/s digital transmission line with no design change for the facsimile device itself.Type: GrantFiled: September 20, 1988Date of Patent: March 20, 1990Assignee: Kokusai Denshin Denwa Co., Ltd.Inventor: Masayoshi Utsugi
