Filed: 1990-01-11
Abstract: PURPOSE:To obtain the subject compound having high quality and decreased content of hydrolyzable bromine and inorganic bromide ion, on an industrial scale at a low cost, by brominating bisphenol A with bromine in methanol while specifying the substrate concentration of the above raw material relative to methanol. CONSTITUTION:Tetrabromobisphenol A useful as a flame-retardant for epoxy resin and ABS resin is produced by brominating bisphenol A with bromine in methanol. In the above process, the substrate concentration of bisphenol A relative to methanol is adjusted to 0.1-10w/v%, preferably 1-8w/v% to obtain the objective compound having high quality. Since the product has remarkably decreased contents of hydrolyzable bromine and inorganic bromine ion, it can be used, without necessitating particular purification process, as a flame- retardant for resin for electrical and electronic use such as laminated sheet or sealant. The compound can be produced on an industrial scale at a low cost with a simplified process compared with conventional process.

Filed: 1978-01-17
Abstract: PURPOSE: To secure the high-speed operation for A-D converter with reduced number of comparators as well as enhanced effective resolution, by adding the counter which counts the number of the picture frames.  
     CONSTITUTION: Vertical synchronous signal SV is supplied to counter CNT and then divided, and the output is voltage-divided with resistance R 4  and R 3 . And addition voltage FC whose voltage value switches between 0 and E in the even field is obtained at the odd field. At the same time, video signal VI is supplied to the base of transistor TrQ via amplifier A and capacitor C. When the base potential is going to lower less than FC, diode D conducts to charge C. As a result, the video signal at the base side of Q is always in agreement with FC. The scale of E is 1/15 the difference voltage between the black and white levels of the video signal and eqivalent to one gradation of the effective luminance. Then video signal VD delivered from the emitter of Q is applied to the plus(+) input of comparators C 1 ∼C 7 , and logic gates G 1 ∼G 4  encode the comparator output to 3-bit digital video signals DV 0  DV 2 .
