Title: Method for unevenly dyeing a cellulose fiber under non-existence of an alkali or a reducing agent
Inventor: TOOMASU MARUTEINI
IPC: D06P1/30
Filed: 1989-09-12
Abstract: PURPOSE: To dye cellulose-based fibers clearly and in fast color by pre-treating the cellulosic fibers with a solution containing a wetting agent, a reaction product of a polyethyleneimine with a bifunctional alkylating agent and an ionic surfactant, and dying the fibers with a reactive dye, etc., without using an alkali or a reducing agent. CONSTITUTION: Cellulosic fibers are pre-treated with a pre-treatment solution containing a wetting agent, a quaternized reaction product of a polyethyleneimine with a bifunctional alkylating agent (e.g. epichlorohydrin, 1,3-dichaloropropane-2-ol, etc.), and an anionic surfactant, thereafter dyed in fast color by using a reactive dye or a sulfur dye without the addition of an alkali or a reducing agent. A dyed product in which warp yarns are nonuniform is obtained by treating a warp yarn consisting of cellulose fibers with a sizing liquor containing the pre-treating agent, weaving them with a white cotton weft yarn, dying them with a reactive dye without the addition of alkali and the weft yarn without pre-treated become white by soaping, etc., to present a mottled fabric expressing denim effects.

Title: Digital transmission frame synchronizing system
Inventor: WATANABE SEIJI
IPC: H04L7/08
Filed: 1988-09-21
Abstract: PURPOSE:To decrease the transmission speed of a transmission line and to prevent out of synchronism by applying angular modulation to a digital signal with a frame synchronizing signal and sending/receiving the modulated result. CONSTITUTION:A multiplex circuit 2 of a terminal station transmission section multiplexes a low degree group signal 9 to form a high degree group signal 10, uses a frame synchronizing signal 14 generated from a frame synchronizing signal generating circuit 3 to apply phase modulation to the high degree group signal 10 and outputs a high degree group signal 12. A phase demodulation circuit 5 of a terminal station reception section demodulates a frame synchronizing signal 16 from the high degree group signal 12 and separates the high degree group signal 12 into the low degree group signal 11 by using the frame synchronizing signal 16. Thus, even if a code error takes place, the frame synchronizing signal is not lost.
