Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To make a lock range of a frequency for each channel constant by calculating a tilt of a tuning voltage for each channel and limiting the tuning voltage depending on the tilt. SOLUTION: In the operation of an automatic tuning memory(ATM), a microcomputer 32 receives a synchronization discrimination result from a synchronization discrimination circuit 30 to detect a start position of presence of a station. Furthermore, the microcomputer 32 monitors an S-curve voltage and compares the S-curve voltage with a reference voltage and then calculates a tuning voltage (PWM value) corresponding to a frequency change from the start of station presence till the S-curve voltage reaches the reference voltage for each channel. The tuning voltage is converted into a voltage equivalent to a prescribed lock range (e.g. ±2MHz) and the lock range is limited by using the voltage in the operation of AFC.

Title: Clutter removal system
Inventor: ONO MAKOTO
IPC: G01S13/90
Filed: 1978-06-09
Abstract: PURPOSE:To make it possible to remove a clutter by selecting the optimum combination of the beam width and pulse width of an antenna, as to a pulse radar which receives scattering power from rain from skies and the ground surface and then observes its state. CONSTITUTION:Rader antenna 1 emits a beam at angle thetaO. When the pulse width of the radar is denoted by (tau) and the velocity of light by (c), the hatching part encircled by Ctau/2 and beam width DELTAtheta is rain observation region 3. Although almost all radiation power is contained in beam width DELTAtheta of the radar antenna 1, part of power is radiated in all directions except DELTAtheta, which is side-lobe radiation. Therefore, the range gate system receives scattering power from AB and A'B' of ground 2 contained in the width of a distance a half (ctau) even by a side lobe and if this reception level is higher than scattering power, the rain observation becomes impossible. Namely, ratio (eta) of rain scattering reception power to ground clutter power should be less than a certain value. For the purpose, the combination of beam width DELTAtheta and pulse width (tau) should be set to the best one.

IPC: B65H9/14
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a positioning system to adjust dispersion of timing. SOLUTION: When a sheet 110 reaches a sensor 158 in the upper steam side of a positioning nip 159, a lead edge of the sheet 110 proceeds to the positioning nip 159 which is made slow down at a prescribed distance and the sheet is curved by a prescribed degree. Then, the positioning nip 159 makes the sheet, whose skew is released, proceed to a second sensor 160 in the down stream side of the positioning nip 159. After that, the positioning nip 159 is stopped and a curve of the sheet 110 in the upper stream side can be formed. Since the lead edge is suppressed by the positioning nip 159, the second curve can be extensive. Consequently, wide dispersion of the timing of the position of the sheet 110 and the position of the image can be adjusted.

Abstract: PURPOSE:To detect higher harmonic components of a three-phase system voltage as instantaneous values by employing three-phase/two-phase conversion, matrix arithmetic, etc., by using a reference sine wave signal synchronized with the system voltage obtained by a PLL and the three-phase system voltage containing the higher harmonic components. CONSTITUTION:Three-phase system voltages Vu, Vv, and Vw are led out of the system through a PT 1 and converted by a three-phase/two-phase converting circuit I 2 into Vd and Vq, which are inputted to an arithmetic circuit I 3. On the other hand, Td and Tq synchronized with the basic wave of a system U phase are obtained by the PT 1, the PLL 4, and a synchronizing sine wave generating circuit 5 and inputted to the arithmetic circuit I 3.

Those Ld and Lq are passed through H.P.F.s 6 and 6' to obtain Ldh and Lqh, which are inputted to an arithmetic circuit II 7 together with the signals Td and Tq and converted into voltage values Vdh and Vqh. Further, a two-phase/three- phase converting circuit 8 obtain higher harmonic components Vuh, Vvh, and Vwh of respective system phases. Those are used as correcting signals to correct the higher harmonic components in the system voltages.
