Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To generate a blur free radar image by estimating the rotational motion of a target based on the shift of a radar image having a time difference produced from the radar echo of target. SOLUTION: A radar image generator 11 receives a radar echo from a target to generate radar images I1 , I2 having a micro time difference Δt which are then stored 121, 122. One-dimensional shift detectors 131, 132 receives the images I1 , I2 and detects the shifts Δx, Δy in the direction of X and Y axes. A linear approximation unit 141 determines a rotational speed ω based on a rotational angle θ obtained by approximating the black point B of Δx with a line ΔX and a time difference Δt. Similarly, Δy is approximated 142 with a line ΔY. A rotational angle detector 15 and a center of rotational angle detector 16 detects the rotational angle and the center thereof, respectively, from processing results ΔX, ΔY.  When the blur is corrected at the time of generating a radar image based on the rotational angle and the center thereof, a radar image free from blur caused by the rotational movement of target can be obtained.

Title: Reset control circuit of integrated circuit
Inventor: SUZUKI TOSHIAKI
IPC: G06F1/00
Filed: 1984-12-28
Abstract: PURPOSE:To obtain an IC reset circuit capable of utilizing a battery capacity at a maximum level at the time of backup by providing a main reset terminal and a subset terminal, both of which connect two different types of voltage detecting circuits, and a resetting state display flag. CONSTITUTION:When a voltage rises to exceed 3.5V after an electric power source is turned on, the terminal 1 comes to a high level, but AND conditions of a gate circuit 6 hold and the reset state is kept, because the terminal 2 is at a low level. When the voltage exceeds 4.8V, both terminals 1 and 2 come to a high level to close the circuit 6, and the flag 5 is cleared to release the resetting of an IC7. At the time of interrupting the electric power source an electric power source from a battery is supplied. When the voltage comes to 4.8V as discharging proceeds, the terminal 2 comes to a low level, however it is not reset because the flag 5 is cleared to close the circuit 6. Then the signal of the terminal 2 is inputted to an interruption receiving circuit to cause the interruption, and a clock speed is switched to a low speed side. When the voltage comes down below 3.5V, the terminal 1 comes to a low level to open the circuit 6, and the flag 5 is set to reset the IC7.

Title: Optical recording medium and optical disk reproducing method and optical disk reproducing device
Inventor: NAKAMURA KOICHI
IPC: G11B7/24
Filed: 1994-11-15
Abstract: PURPOSE: To lower the crosstalks by the signals from adjacent tracks and to lessen the deterioration in signal characteristics by thermal influence of a laser by providing the surface of a substrate with phase shift layers. CONSTITUTION: This optical recording medium is formed by successively forming lands 2 and grooves 3 on the substrate 1, providing the substrate with the phase shift layers 4 on these lands 2 and further, successively laminating a lower dielectric film 5, a recording film 6, an upper dielectric film 7, a reflection film 8 and a UV curing resin 9. The reproduced light reflected on the recording film 6 and transmitted through the lands 2 is made nearly zero in light intensity at the boundaries between the adjacent tracks by providing the medium with the phase shift layer. Since the interference by the phase differences is generated between the recording signals of the lands 2 and the recording signals of the grooves 3, the crosstalks between the signals of the adjacent tracks are decreased.  The track grooves are made deeper than heretofore and the thermal influence that the high-output laser exerts on the adjacent tracks at the time of recording and erasing the information is lessened. The deterioration in the signal characteristics of the optical memory medium is thus lessened.
