Title: Device and method for searching target for traveling object
Inventor: SUZAKI HARUO
IPC: F42B19/10
Filed: 1991-08-23
Abstract: PURPOSE:To elongate the target searching distance of a target searching device irrespective of the dimensions and shapes of traveling objects. CONSTITUTION:After deciding the azimuth of a fellow surface vessel other than a target and storing the information in the limited azimuth direction 15 of a torpedo, the torpedo is discharged and acoustic waves are outputted from the surface vessel before or after discharging the torpedo. The acoustic waves are propagated through sea water and reflected all around by a target. The reflected waves are received by mean of a receiver 11 after they are propagated through sea water and outputted to a reception processing section 12. Since the section 12 inputs azimuth information 31 from the section 15 and invalidates signals received from the azimuth of the surface vessel, the torpedo can be prevented from advancing toward the fellow surface vessel. The torpedo searches and attacks the target while the torpedo is controlled by means of an attitude control section 13 so that the invalidated acoustic waves reach the highest level and operated by a power section 14.

Filed: 1989-09-13
Abstract: PURPOSE:To control the output stably and correctly by comparing an output reference signal, which changes in ramp form to a target output at a specific rate of change in output, with an actual output and driving a load limiter setter at a rate of change which links up with said rate of change in output. CONSTITUTION:The output of a target output setter 8 and that of a rate-of- change-in-output setter 9 are entered to an output reference setter 10 to set output reference value MWD increasing gradually. The actual output MW of a generator 2 is detected (19) and compared (11) with the MWD. Requirements that MWD>MW+alpha% and MWD<MW-alpha% (where alpha=0.25) are detected with output signals 11A and 11B. When the MWD increases, the signal 11A is satisfied and a raising command is given to a load limiter setter (LL) 5. The output of the rate-of-change-in-output setter 9 is increased by a factor of 1.5 (17) and sent to the LL 5. If the MW fails to follow the rise of the MWD, a comparator 12 produces a signal to establish a retracting requirement 16 and the raising and lowering commands of the output signals 11A and 11B are given to the LL 5 unconditionally. Thereby the output is controlled stably and correctly for unclear power generation.
