Title: Production of pigment dispersion
Inventor: KATO SHIGEKI
IPC: C09D17/00
Filed: 1987-12-01
Abstract: PURPOSE:To obtain in high efficiency the title dispersion capable of affording printing ink and coatings with excellent clearness, coloring power and gloss, by incorporating a pigment with an amine-based cationic surfactant and pigment derivative in specified proportions followed by kneading in combination with a thermoplastic resin and plasticizer. CONSTITUTION:The objective dispersion can be obtained by incorporating (A) (i) 100 pts.wt. of a pigment (e.g., at least one kind selected from phthalocyanine, azo, quinacridone, dioxazine and carbon black) with (ii) 0.1-20 pts.wt. of an amine-based cationic surfactant and (iii) 0.1-35 pts.wt. of a pigment derivative [e.g., of the formula (P is organic coloring matter residue; X1 and X2 are each H or halogen, number of the halogen atom j of >=2; i and j are each 1 to 4)] followed by kneading, using a roll mill, in combination with (B) a thermoplastic resin (e.g., cellulose derivative) and (C) a plasticizer. Even use of nitrocellulose as the resin B will eliminate the danger of ignition because of highly efficient kneading operation at high temperature and viscosity.

Title: Data transmission method
Inventor: SUZUKI MASAAKI
IPC: G06F17/40
Filed: 1990-11-09
Abstract: PURPOSE:To prevent the deterioration in the processing efficiency of a CPU by sending a routine transmission data while its period is extended when a state change takes place in a state change transmission data and the operating rate of the CPU of an information transmitter sending the state change transmission data exceeds a prescribed operating rate. CONSTITUTION:When a state change takes place in a state change transmission data I3 in a timing 2, a sender side information transmitter sends two kinds of routine transmission data I1, I2 at original transmission periods T11, T12 and the state change transmission data I3 while its transmission period T13 is changed into a shorter transmission period T23 to a receiver side information transmitter. As a result, when the transmission processing quantity of the state change transmission data is increased and the operating rate of the CPU of the information transmitter exceeds 85%, the sender side information transmitter revises the transmission periods of the routine transmission data I1, I2 into the transmission periods T21, T22 longer than the original transmission periods T11, T12 in a timing 3 and sends the routine transmission data I1, I2. Thus, the deterioration in the processing efficiency of the CPU is prevented.
