Title: Quantizer
Inventor: KANEAKI TETSUHIKO
IPC: H03M7/36
Filed: 1990-04-06
Abstract: PURPOSE:To reduce the gradation of a local quantizer in a sub loop by differentiating the output of a 2nd local quantizer in response to the degree of a 1st noise shaping quantizer, adding the differentiating output to the output of a control means, and extracting the result as an output. CONSTITUTION:A control circuit 5 adds the output C of an amplitude detector 11 and the output Q1 of a local quantizer 1 at an adder 20, and a limiter 21 is used to prevent the sum from being in excess of -3 to +3. Assuming a quantized error caused from a local quantizer 1 and the control circuit 5 as Vq1, then the output of a subtractor 2 goes to -Vq1. On the other hand, the input to a local quantizer 6 results from subtracting the quantizing error Vq1 from a feedback beta by a feedback circuit 9 and becomes smaller than the feedback beta without fail. Moreover, the input is suppressed below an input limit of the local quantizer 6.

Filed: 1988-04-14
Abstract: PURPOSE:To reduce the cost of a steel stock and to increase the adhesion force to concrete by using a grooved roll having a V-shaped projection at the groove center and performing light draft rolling of the steel stock by one hot pass. CONSTITUTION:For a hot rolling mill, a box groove 5 is formed on a roll 3 of one stand of a finish tandem mill group and a V-shaped projection 6 (knifing web) is formed at the center of the groove. A steel stock 4 flatly rolled by a rough tandem mill line is carried into a finish mill and is lightly rolled by the grooved roll 3 in a prescribed one stand. In that time, a V-shaped projection is formed on the stock 4 by the web 6 and a side angle theta of the projection is brought to be >=90 deg.. The cost of the steel stock 4 is reduced because the projection forming is enough by one pass light draft rolling and the adhesion force to concrete is increased by forming a side angle theta of >=90 deg. of projections.
