Title: Improved manufacture of high chloride planar particle emulsion
Inventor: JIYOO EDOWAADO MASUKASUKI
IPC: G03C1/015
Filed: 1991-12-06
Abstract: PURPOSE: To produce a plate-like particle emulsion in which a photographic increasing agent is efficiently compatible with an adsorption adduct by specifying the concn. of the chloride ion and isocyanate ion in a dispersion medium and controlling the concn. to promote the formation of a flat particle. CONSTITUTION: An emulsion consisting of a radiation-sensitive silver halide particle is produced by introducing silver ion into a chloride ion-contg. dispersion medium. Thiocyanate ion is added to the dispersion medium by 2-30mmol/l before the silver ion is introduced to control the formation of the particle core to promote the formation of a (111) crystal face. The chloride ion concn. in the medium is kept at >=0.5 molarity in the presence of the thiocyanate ion to introduce a parallel twin plane in the particle. The isocyanate ion in the medium is maintained at 0.2-10mol% based on the total amt. of the introduced silver to control the growth of the grain to promote the formation of the plate- like particle having a parallel (111) main crystal face.

Title: Pll and video signal recorder
Inventor: EZAKI KUNIHIRO
IPC: H03L7/08
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce a tracking time when a phase of an input signal is largely changed and to keep a period of an output signal from a subordinate frequency divider stable. SOLUTION: A frequency divider of a PLL is made up of a subordinate counter 24 and a host counter 21. The subordinate counter 20 and a decoder 23 frequency-divide a clock whose frequency is a/N into 1/L and the host counter 21 and a decoder 22 frequency-divide the clock whose frequency is a/N into 1/H. The PLL generates an output signal of a multiple of N(=L×H). When a phase change in an input signal is large, a load value, e.g. 0 from a load value control circuit 25 is loaded to the host counter 21 by using an edge detection signal of the input signal as a load signal. On the other hand, no load value is loaded to the subordinate counter 20. Thus, the tracking time of the N-multiple output with respect to a phase change of an input signal is reduced and the period of the output signal from the subordinate counter 20 is kept stable.
