Title: Navigation satellite signal receiver
Inventor: TATEDA YOSHIFUMI
IPC: G01S19/26
Filed: 2001-08-10
Abstract: PROBLEM TO BE SOLVED: To catch a weak signal in a short scanning time in a navigation satellite signal receiver used in a navigation device. SOLUTION: A scanning dedicated channel performing only the scanning of a satellite signal is installed in addition to a scanning tracking channel scanning and tracking a satellite signal. A carrier frequency of the satellite signal or the phase of a pseudo noise code is estimated with an arithmetic means. In the scanning tracking channel, integral action time for evaluating correlation is shortened and a range where the shift between a code phase and a frequency is estimated at the maximum is scanned. In a scanning dedicated channel, the integral action time for evaluating correlation is lengthened to enhance sensitivity, and the limited range having high probability is scanned. Even if the carrier frequency or the phase of the pseudo noise code is largely shifted, a signal is quickly caught unless a signal is weak.  The signal is relatively quickly caught even if the signal is weak unless the carrier frequency or the phase of the pseudo noise code is large.

Abstract: PROBLEM TO BE SOLVED: To provide an electroplating method which is capable of adequately suppressing the C camber produced in an energizing unit while adequately assuring the energization to a steel strip without adding a drastic change to the conventional electroplating plant in electroplating of the steel strip by a horizontal continuous plating plant. SOLUTION: In the electroplating method for the steel strip by the horizontal continuous plating plant equipped with the energizing unit consisting of an energizing roll and a backup roll, the electroplating method for the steel strip is used which comprises correcting the camber of the steel strip by passing the steel strip previously corrected of the camber in a transverse direction through a plating line and holding the steel strip between a pair of the upper and lower rolls varying in the contact lengths with the steel strip on the upstream side and/or downstream side of a portion or the whole of the energizing unit, thereby imparting the camber of the direction opposite to the direction of the warpage of the steel strip produced when passing the energizing unit.  The effect is higher if liquid draining rolls disposed in a plating bath are adopted for the pair of the upper and lower rolls varying in the contact lengths with the steel strip.
