Title: Amplitude jitter suppressing system
Inventor: HIRAGUCHI MASAYOSHI
IPC: H04L27/38
Filed: 1990-05-21
Abstract: PURPOSE:To suppress amplitude jitter without causing the amplification of unnecessary noises by detecting the amplitude jitter frequency of a reception signal and performing amplitude correction by extracting only the component of the amplitude jitter from the receiving signal. CONSTITUTION:This system is provided with an amplitude error calculating device 6, a band filter 8 forming an amplitude jitter component output means, a frequency transform circuit 10, a selective circuit 11, a coefficient table 12, a complex multiplier 2 forming a receiving symbol output means, a decision device 4, and a conversion circuit 9. An amplitude error signal 7 is determined from a complex base band signal 1 and a reception symbol 5 by the amplitude error calculating device 6, and the frequency conversion circuit 10 converts the amplitude error signal 7 to a frequency area by Fourier transformation. The selective circuit 11 compares the output of the frequency conversion circuit 10 with a predetermined threshold, and specifies the amplitude jitter frequency. Furthermore, the coefficient groups of the band filter 8 suppressing the specified amplitude jitter frequency are selected from the coefficient table 12 to be set to the band filter 8. Thus, the effect of jitter suppression can be obtained without causing the amplification of noises.

Title: Method and device for coating hollow substrate with catalyst
Inventor: TOMASU SHIMUROTSUKU
IPC: B01J37/02
Filed: 1995-05-01
Abstract: PURPOSE: To coat a uniform coating of desirable concentration by detecting a direction of a substrate to a dip pan and returning the substrate to the original position after interruption movement of the substrate by preventing movement of the substrate into the recess of the dip pan when the substrate is directed to such direction as the substrate can not be placed correctly into the recess of the dip pan. CONSTITUTION: When a hollow substrate 21 is moved from the starting position so as to go forward to a recess 84 of a dip pan 30, and the end of the substrate 21 passes a plane positioned above the recess 84 and crosses a traveling pat of the substrate 21, direction of the substrate 21 to the dip pan 30 is detected. By this detection when the end of the substrate 21 is in the direction not capable of inserting into the recess 84 accurately in order to dip into catalyst slurry introduced into the recess 84, movement of the substrate 21 to the recess 84 of the dip pan 30 is prevented. And, after interrupting the movement of the substrate to the recess 84 of the dip pan 30, the substrate 21 is returned to the starting position. Accordingly uniform concentration coating can be directed.
