Title: Reception synchronizing device by chirp signal
Inventor: TANAKA YOSHIFUMI
IPC: H04B1/707
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To detect the deviation of a reference frequency of transmission and reception even in the case of a low S/N by detecting a frequency having the maximum value between the power frequency spectrum of an output of a 1st restoration circuit and the power frequency spectrum of an output of a 2nd restoration circuit. SOLUTION: A 1st restoration circuit 7 restores spread spectrum to an intermediate frequency chirp signal r (t) 3 which is obtained via frequency conversion of a transmission chirp signal. A 2nd restoration circuit 8 restores spread spectrum after execution of a prescribed frequency offset of the intermediate frequency chirp signal r (t) 3. A detecting part 9 detects a frequency having the maximum value among the power frequency spectrum of an output of the circuit 7 and the power frequency spectrum of an output of the circuit 8. Thus, a signal can be detected even when a reception S/N is low, the deviation of a reference frequency of transmission and reception can be corrected with the detected signal and a reception frequency and a clock timing can be quickly synchronized.

Chromated films 24, 28 containing an amount of not more than 400mg/m<2> in terms of metallic chromium content are laminated onto the plated layers 12, 22, if necessary. The chromated films improve pain adhesion and resistance to corrosion. Furthermore, an organic coating 30 composed of resin whose glass transition temperature is 60-120 deg.C, or an organic coating 30 composed of a mixture of resin whose glass transition temperature is 60-120 deg.C with silica, as coating, is laminated onto the chromated layer 28 to form a surface-treated steel sheet. The surface-treated steel sheet thus obtained has very excellent resistance to low-temperature chipping and water-resistant secondary adhesive properties.

IPC: G01S3/44
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To correct an off-set error contained in an output of a gyrosensor quickly and reliably in an on-vehicle satellite signal receiver. SOLUTION: A signal received by an onboard antenna 10 is sent to a control apparatus 26 through a BS tuner 14. The control apparatus 26 carries out gyro tracing in the case the reception level is a prescribed level or higher and hybrid tracking, in which step track controlling extent is overlaid on the gyro output, in the case the reception level is lower than the prescribed level and at the time of shifting from the hybrid tracing to the gyro tracing, the gyro off-set error values are integrated and off-set correction is carried out after a reference time passes. After the off-set correction is carried out and in the case the off-set error becomes small, the reference time is gradually increased, so that the off-set error correction can be carried out quickly and highly precisely.

Filed: 1977-11-04
Abstract: PURPOSE: To prevent the ill effect given to the effective surface due to occurrence of spring-back at the skirt part by deforming the shadow mask shape, and thus to obtain an extremely stable and high-rigidity shadow mask.  
     CONSTITUTION: For shadow mask 9 of the color picture tube, a nearly identical relationship is secured between the swell-out curvature of effective surface 9b and the curvature of effective surface 9b at skirt part 9c. Accordingly, part 9c is perfectly free from the effect caused by squeeze and extension given through the press formation except for corner part 9d. In other words, the spring- back occurrence is eliminated completely at part 9c. Furthermore, both curved surfaces of part 9c and surface 9d prescribe their shapes to each other, so the rigidity can be increased greatly at part 9c.
