Title: Delay detection circuit
Inventor: AOYANAGI TAKATOSHI
IPC: H04L27/227
Filed: 1990-01-31
Abstract: PURPOSE:To keep an excellent reception characteristic even when a frequency offset is increased due to fluctuation of the frequency of a reception signal by detecting the frequency offset of the reception signal and rotating a phase of a delay signal outputted from a delay circuit to cancel the phase rotation of the reception signal due to the frequency offset. CONSTITUTION:A phase rotation circuit 9 rotating a phase of a delay signal to correct a frequency offset based on a phase rotation component detected by a phase rotation detection circuit 8 connects to the input of a delay circuit 1. That is, the phase rotation circuit 9 rotates the phase of the delay signal outputted from the delay circuit 1 so as to cancel the phase rotation of the reception signal due to the frequency offset based on the phase rotation component due to the frequency offset detected by the phase rotation detection circuit 8 through the elimination of a modulation component from a base band detection signal. Thus, even when the frequency of the reception signal is fluctuated, an excellent reception characteristic is obtained.

Abstract: PURPOSE:To correct the deviation angle of the traveling direction of a moving body which is detected by an earth magnetism sensor by providing a means which correct the traveling direction of the moving body displayed as a current position according to the direction of a traveling expected course on a map. CONSTITUTION:If the display mark M1 of the current position of the moving body and the display mark M3 of a traveling track deviate from the traveling expected course where target points O1 and O2 on the map are set, the mark M1 and M2 are moved first in parallel under the control of a CPU 3 according to the operation input of target point passage from an operation device 8 so that the mark M1 comes to the point O2 as shown in a figure A. Then when the current position of the moving body and the traveling track are corrected automatically at the point O1, the point P1 on the mark M1 at the point O1 is stored previously and the mark M3 is rotated around the mark M1 so that the point P1 in the figure A comes to the last point O1, thereby setting the mark M3 between the points O2 and o1 as shown in a figure B. Then, the CPU 3 rewrites position data on the moving body which deviates from the expected course into respective automatically corrected position data.

Title: Ignition timing control system for marine engine
Inventor: UMEHARA KAZUHIRO
IPC: F02P5/14
Filed: 1989-01-31
Abstract: PURPOSE:To prevent an engine stall from occurring by advancing ignition timing several times being set at time of normal trawling in the case where a sudden load change occurs due to load connecting or separating operation to be performed at time of low speed rotation. CONSTITUTION:When an engine is started in a neutral state, an ignition timing controller 30 first ignites at ignition timing I7 of starting timing advance for engine starting, and after the elapse of starting timing advance setting time, it shifts to some ignition timing to be determined by a timing switch 35A, among trawling ignition timings I1-I5. For example, when I1 is the case, throttle opening being detected by a sensor 33 is less than the specified value, and when shift operation is performed to forward or backward movement in this state, a neutral switch 51 is turned off, and trigger output is issued to each gate of thyristors SCR1-SCR4 at the ignition timing of I6 from a microcomputer 30 via a trigger output buffer 32, and at a moment shifted, the ignition timing is advanced from I1 to I6 several times more than at time of normal trawling. Thus, any engine stall is preventable.
