Title: Automating equalizer initializing system
Inventor: TAKAOKA KAZUHIKO
IPC: H04B3/10
Filed: 1988-01-29
Abstract: PURPOSE:To shorten a convergent time of a equalizer by calculating a receiving quality by means of the square sum of an error signal to be a binary signal at the time of tap coefficient updating due to a data signal, weighting an updated gain when as equivalent residual exists because of the bad receiving quality for a set section from the receipt of the data signal, and controlling the updated gain of an equalizer. CONSTITUTION:When the CD signal of a training signal arrives at the prescribed tap position of an equalizer 2, the same pattern as the sent data in a CD period is outputted from a reference signal generator 5. Here, when line distortion is left at the information data, that is, when the equivalent residual is large, the square sum of the error signal of a received quality calculating circuit 8 becomes larger than a fixed threshold TH. Thus, for the constant section of the information data receipt, the AND of a timer 8 output is obtained by a tap updating/weighting circuit 9, the selector of an equalizer coefficient control circuit 7 selects beta, and the tap updated gain is largely weighted. For this reason, the convergent speed of the equalizer is enhanced, an error does not continue, and the data can be correctly and promptly obtained.

Title: Method for correcting time delay of shaker in vibration simulation of structure
Inventor: MARUTA EIZO
IPC: G01M9/00
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To determine a constant ai without the need for a large number of trials or skill by using a numerical value obtained by optimization dependently on a frequency (natural circular frequency ω) as the constant ai in computing an instruction value after response delay compensation. SOLUTION: A bed 7 connected to a rotation bearing 6 at the lower end part of a support 5 is moved forward and backward via a computer-controllable servo motor 8 and a ball screw mechanism 9 to shake a rigid model 4. Then the amount of shaking measured by a magnet scale 11 is changed according to values subjected to arithmetic processing by a computer on the basis of the output of a load cell 3. As response delay occurs in the movements of a shaker due to forced driving, the results of real operation are matched with the results of computer computations by providing an instruction value X (t) after response delay compensation.  In computing the instruction value X (t) in the equation (in the equation X' (ti) is a past measured value, τ is previously grasped response delay time, and ai is constant), the constant ai is not a fixed value but a numerical value obtained by optimization dependently on a frequency (natural circular frequency ω) is used instead.

Title: Lighting arrester circuit for line repeater

IPC: H04B3/36
Filed: 1978-02-17
Abstract: PURPOSE:To ensure an effective arrest of the lighting with a small-sized circuit with reduced number of component parts by earthing the center electrode of the triode self-release lighting arrester tube and connecting other two electrodes to each middle point of the line transformer. CONSTITUTION:The center electrode of triode self-release light arrester tube 31 is earthed, and other two electrodes are connected to each middle point of line transformer 16 and 18, with power circuit 27 inserted between middle points. If the lighting surge is generated at input terminal 11 and 12, the surge is dropped down onto the earth through primary coil 16p and by the discharge of the electrode of one side in tube 31. In this case, the surge current flows to coil 16p as well as between terminal 11 and 12, but the magnetic flux occurring at coil 16p is backward and is not conducted to repeater internal circuit 19. In the same way, the lighting surge generated at output terminal 24 and 25 is discharged to the earth and not induced to the repeater internal circuit. Thus, an effective lighting arrest is ensured with a small-sized circuit with reduced number of component parts.
