Abstract: PURPOSE: To obtain a level dyeing agent for a reactive dye, containing a specific quaternary ammonium salt and capable of levelly dyeing fibers without deteriorating the final dyeing concentration by adding thereof to a dye bath containing the reactive dye. CONSTITUTION: This level dyeing agent for a reactive dye is obtained by adding 0.5-5g/l, preferably 1-3g/l level dyeing agent comprising a quaternary ammonium salt, represented by the formula [R1 to R4 are each a 1-22C alkyl, an alkylphenyl, phenyl, an alkylbenzyl or benzyl; A is C2 H4 or CH2 -CH(CH3 ); (n) is 1-100; X<-> is a halide ion] and having an ester bond in a dye bath containing the reactive dye having various reactive groups.

Title: Digital pll circuit
Inventor: KAMANAKA NOBUO
IPC: H03L7/06
Filed: 1983-12-28
Abstract: PURPOSE:To obtain a simple, small-scale PLL circuit by performing frequency division, phase operation, and phnase comparison by a ring counters composed of shift registers and a gate circuit. CONSTITUTION:A clock S6 of frequency which is six times as high as that of the input clock phiIN of an oscillator 6 is outputted. A change point detecting circuit 7 detects a change point of the input clock phiIN and outputs an edge signal S7. A phase difference detecting circuit 21 detects the phase difference between the input clock phiIN and ring counter 20 and decides that the input clock phiIN synchronizes with an output clock phiOUT when the edge signal S7 is 1 and the output Q of a flip-flop F3 is 1. At this time, inputs to a switch control circuit 8 are both 0 and the number of stages of the ring counter 20 does not change. When the edge signal S7 is 1 and a flip-flop F1 or F2 outputs 1, a step out occurs and the number of the stages of the ring counter changes, so that the output clock phiOUT follows up the input clock phiIN.
