Abstract: PURPOSE:To obtain the approximately accurate position of a ship, by computing a plurality of dead-reckoned present positions, computing the present position group by assuming the speed of a tidal current, making the mean value as a true present position, and determining the assumed tidal current speed as a true tidal current speed. CONSTITUTION:A position reckoning device 1 comprises a navigation signal receiver 11 and a coordinate converter 12 and outputs a reckoned position signal Sp as a digital signal. A moving distance measuring device 3 comprises a log indicator 21, an azimuth meter 22, and a vector converting circuit 23, and outputs a speed signal Sv. The reckoned position signal Sp and the speed signal Sv are stored in a memory circuit 3, and computed in a computing circuit 4. The computing circuit 4 obtains the moving distnce of the ship with repect to the water by multiplying the log speed Sv and the time at first, then obtains a plurality of the dead-reckoned positions, further obtains the present position group, and computes the deviation of the present position group. The present position whose deviation value is the smallest is made to be the true present position, and the corresponding assumed tidal current speed is determined to be the true tidal current speed.

Title: Printer sheet feeding structure for handy terminal
Inventor: KAWAKAMI KENJI
IPC: B41J15/04
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent a printer roll sheet from creasing at the time of setting a roll sheet in a paper holder by transmitting a rotational force to the roll sheet for printer at the time of turning a paper feed dial, inserting the forward end part of the roll sheet between a paper feed roller and a print roller through a separator and a paper guide and then turning the roll sheet. SOLUTION: When a paper cover 11 is opened and a roll sheet 12 is set in a paper holder 10, the roll sheet 12 touches a rotary roller 14 through action of a tension spring 13. When a paper feed dial 9 is turned under that state, a paper feed roller 18 is turned counterclockwise. The rotary roller 14 is set to turn clockwise while touching the paper feed roller 18 tightly and since the roll sheet 12 is touching the rotary roller 14 tightly, the paper feed dial 9 can be turned and the turning force can be transmitted to the roll sheet. Since the finger of an operator does not touch the forward end of a printer sheet directly when it is set, the printer sheet is not creased.
