IPC: H03G5/00
Filed: 1993-06-25
Abstract: PURPOSE: To enable function as an efficient DSP filter with few circuit elements by increasing the number of acoustic signals to be samples in a low-frequency band and reducing that number to be sampled in a high-frequency band. CONSTITUTION: An audible frequency band, sampled at a prescribed frequency, is divided into a large rubber of bands by band filters 11-13. Band-divided acoustic data are extracted at ratios which are mutually different for hands by extracters 14-16. The distortion in extracted acoustic data is corrected by bands by FIR filters 17-19. The distortion-corrected acoustic data are synchronized and synthesized out by synthesizing parts 20-22, so as to be the same order as acoustic data at the time of inputting them to the frequency band dividing means. Band filters 23-25 remove the noise of data which are outputted from the synchronizing parts 20-22.

IPC: B21B39/08
Filed: 1993-06-25
Abstract: PURPOSE:To control L-camber, C-camber to arbitrary values and to improve the quality of a steel strip by providing auxiliary rolls which can adjust their positions respectively in the height direction just before or just after the front stand of two continuous stands and just after the rear stand. CONSTITUTION:When the outlet side pass angle theta1 of the front stand is changed, for example, it is enlarged, the winding angles to the work rolls of the steel strip S change, are large to the upper roll, and small to the lower roll. Consequently, the compressed residual stress on the rear side expands and an upward camber is expanded. An outlet side pass angle theta2 of the rear stand 4 is adjusted to enable adjusting both suitable L-camber and C-camber. In this way, the skin pass L-camber and C-camber can be controlled to arbitrary values irrespective of the roughnesses of the work rolls and the quality of the steel strip is improved.

IPC: G01R19/165
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To eliminate cost increase, installation space increase, and the complexity, with a simple structure by giving reverse time limit characteristics whose protection operation time changes by a current value flowing through an apparatus in the case of conducting overcurrent protection of the apparatus when the output value of an integral means exceeds a set rate.
