Title: Forecasting method for period of tidal current commutation
Inventor: SAGA MUTSUNORI
IPC: G06F19/00
Filed: 1985-10-31
Abstract: PURPOSE:To remove the unstability of forecasting right before communication and to prevent an error due to the singular state of communication from being generated by changing the continuous update of a correction angle to the forecasting of a communication period by smoothing convergence based upon a approximate expression of a flow velocity almost at the final commutation period. CONSTITUTION:A tidal current sensor 2 is installed on the bottom of a channel or narrow waterway and an observation signal is processed by a data processor 3 to output forecasting data to a display board 5 or speaker 7 through a signal device 4. The processor 3 stores tidal current data for a certain period and generates the approximate expression indicating past observation data on the basis of them. The difference between an estimated value and an observed value at the time of observation data acquisition forecasted by the approximate expression is calculated and grade evaluation is performed at every constant interval of time, thereby calculating and forecasting a commutation period by the correction angle. Then, the approximate expression of a flow velocity is generated based on measured values almost at the final commutation period and the continuous update by the grade evaluation is changed to the calculation and forecasting of the communication period by smoothing convergence based upon the approximate expression of the flow velocity.

Title: Voltage buffer amplifier
Inventor: ETO TOSHIYUKI
IPC: H03F3/343
Filed: 1988-09-28
Abstract: PURPOSE:To attain low power consumption and low distortion by varying a value of a current source connecting to a source of a buffer transistor(TR) proportional to the amplitude of an input signal. CONSTITUTION:A load is connected to an output terminal OUT in a voltage buffer amplifier circuit. At first, an output current is supplied from a TR Q4 at a positive half cycle of an input signal. In this case, the drain current of the TR Q4 is the sum of an output current and a drain current of a TR Q3 being a component of a variable gain current mirror circuit 1, and since a TR Q2 is deeply turned on by an input signal, a very small on-resistance is obtained by setting the size of the TR Q2 properly. Moreover, the output current is supplied from the TR Q3 at a negative half cycle of the input signal. Since the TR Q2 is deeply turned off as the amplitude of the input signal is increased, the current gain of the current mirror circuit 1 is increased. Thus, the drain current of the TR Q3 is increased and the current is sufficiently supplied in response to the increase in the output current, then no waveform distortion is caused.
