Abstract: PURPOSE:To reduce power consumption required for updating tap gain by using the size or the variation of the error of a transversal filter part or both of them as the criterion of whether the filter characteristic of the adaptive equalizer device for digital communication to be updated or not. CONSTITUTION:An output error e(t) is estimated by an error estimating part 3 on the basis of the output x(t) of the transversal filter part 1 and an estimated value a'(t) outputted from a data judging part 2 or the output a(t) of a training reference signal generating part 6. The tap gain of the transversal filter part 1 is updated by a tap gain updating part 4 so that this output error e(t) becomes minimum, and simultaneously, the size or the variation of the output error e(t) or both of them are evaluated by an error judging part 7, and it is judged either to update the tap gain of the transversal filter part 1 or to execute arithmetic operation necessary for updating the tap gain. Thus, the number of times of the arithmetic operation of the tap gain necessary for updating the filter characteristic can be reduced to extent at which the data judging part 2 does not cause a judgement error.

Title: Method for draining off liquid on rolling mill
Inventor: FUJINO SHINJI
IPC: B21B27/10
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient liquid draining-off effect by arranging a wiping- away device for rolling oil stuck to the surface of a roll and linking the action thereof to the action of a roll bending device. SOLUTION: As the wiping-away device, an air wiper nozzle 7 is arranged in the diagonal downward adjustment to an upper intermediate roll 2 in the inlet side of the rolling mill besides air wiper nozzles 6. The air wiper nozzle 7 injects the air in the direction (the diagonal downward direction) opposite to the rising direction of the rolling oil which is transferred from work rolls 1 to intermediate rolls 2 and raised and the rolling oil is blown off to both end sides of the rolls and wiped away and removed. The air wiper nozzle 7 is controlled by an air wiper control part 10 so as to work only when a roll bender force becomes a fixed value or higher (e.g., the bender force of the intermediate roll 2 becomes >=8ton/roll). By this method, it can be prevented that the rolling oil flows out to the rolling mill outlet side and spattered on a sheet surface.

Title: Graphic display device
IPC: G09G5/02
Filed: 1992-11-19
Abstract: PURPOSE:To speed up scan line processing by outputting a code indicating the in-word position of a matching dot according to word data. CONSTITUTION:When a CPU 2 accesses a display memory (VRAM) 1 of plane constitution, 16-bit data 3 are read out of four planes and inputted to four color comparators 6 respectively. One different bit is inputted from a color information register 5 to each of the color comparators 6. Each of the comparators 6 outputs a signal indicating whether or not the respective bit values of the 16-bit data of the corresponding plane matches with the value of the one bit from the color information register 5, from respective exclusive OR gates. Each plane selecting means 4 outputs a bit value showing whether or not the color that the dot data represents matches with a border color set in the color information register 5 in bit units. Further, a coordinate position detector 9 converts the dot position of the border color in the word into coordinate values and passes them to the CPU 2 through hardware.
