Patent JP-S62240885-A (JP)
Title: After-storage correlation type ultrasonic detector and display
Inventor: KATAYAMA SUSUMU
IPC: G01S7/62
Filed: 1987-02-06
Abstract: PURPOSE:To enable a noise to be simply and easily removed by storing detection information before a correlation processing and correlating the adjacent read-out signals with each other among the read-out signals on the storage readout side. CONSTITUTION:Detection information is transferred to a main memory unit 22 via a terminal 22e and written in a RAM 75. The information read out of the RAM 75 is fed via a shift register 79 and the output of D1 of the register 79 and the output of D2 that is delayed from the output of D1 by one bit, that is, the two outputs D1 and D2 which are adjacent to each other in readout are given to a ROM 78. The ROM 78 is a code converter and the two pieces of information of D1 and D2 are converted to different pieces of information in the ROM 78. In the usual reflected and received signals of a fish finder in general, since no extreme difference is present between one piece of detection information and a subsequent piece of detection information, it scarcely occurs that the preceding detection information has no signal and the present detection information is received at a high level. On the other hand, since interference noises generated when the transmission signals of another fish finder are directly received are generally strong, when either of the two pieces D1 and D2 of information has no signal, the detected signal is forcibly invalidate so that the interference noises can be removed.

IPC: G02B7/28
Filed: 1984-02-14
Abstract: PURPOSE:To attain satisfactorily automatic focusing despite of the generation of shift on an axis by providing a means which detects a position shift between the otpical axis of the irradiated laser light and the center axis of a photodetector by said photodetector and then shift the photodetector based on the detection output. CONSTITUTION:The variance is sometimes produced between the optical axes of the laser light 2 (shown by solid lines and the center axis of a photodetector 11 when a lens 4 is driven for tracking of the light 2. Under such conditions, the light quantity irradiated to photodetecting surfaces 11b and 11d changes. Therefore a differential amplifier 16 which uses the outputs of the surfaces 11b and 11d as two inputs is activated to deliver the error component between both surfaces 11b and 11d. This error output is amplified by an amplifier 17 and applied to a piezoelectric element 18. Then the detector 11 to which an end of the element 18 is attached is driven in the tracking direction to obtain the coincidence between the optical axis of the light 2 and the center axis of the detector 11. In this case, the element 18 uses a lamination type one and the detector 11 can be shifted with the expansion/contraction of each piezoelectric element in its thickness direction.
