Abstract: PURPOSE: To reduce distortion inside an output signal and to improve a dynamic range by providing a pair of input transistors to form a differential pair, current mirror having two transistors at least, and a sync transistor. CONSTITUTION: A differential input stage 20 receives differential digital signals from inputs IN and IN' and converts these signals to non-differential signals at a node N3 in order to drive a buffer 21. The inputs IN and IN' are coupled to transistors (TR) 22 and 23 to form the differential pair, and the TR 22 and 23 are coupled to load transistors (TR) 24 and 25 to form a current mirror at nodes N3' and N3. The source electrodes of the TR 22 and 23 and the drain electrode of a current source transistor (TR) 26 are coupled at a node N4. The gate electrode of the TR 26 is coupled to the node N3 and its source electrode is coupled to a ground potential Vss respectively. Negative feedback due to the TR 26 in response to a signal on the node N3 decreases the sensitivity of the stage 20 for common type signals on the inputs IN and IN' and a noise coupled to the stage 20 by power sources Vcc and Vss. Idle operation conditions have the inputs IN and IN' bias-loaded to a bias voltage almost equal with Vcc/2.

CONSTITUTION:An opening is provided toward the direction 22 of waves on a seabed surface 21, and partition plates 8 and 9 are lifted, so as to fix click 16 to a metal stopper 17. When the front end 23 of the crest of a wave comes to the opening of a sand catching element 3, a door 6 opening inward is made to open by the speed of a wave motion, and the drift sand flows into the sand catching element 3 therethrough. Since the sand catching element 3 is surrounded by a net, a fluid passes therethrough, while the sand is deposited in a sand storing box 1. A door 9 opening inward is closed in the meantime, and therefore the drift sand does not flow into a sand catching element 4. When the front end 24 of the trough of the wave comes to the opening of the sand catching element 4, the direction of the flow speed turns to be reverse to the direction of advance of the wave, a door opens while the door 6 closes, and the drift sand flowing to the right is deposited in a sand storing box 2. At the time of completion of measurement, the partition plates 8 and 9 are closed, an apparatus is lifted, and the volume of the sand in each of the sand storing boxes 1 and 2 is determined. Thereby, the entire flow rate of the drift sand passing through the openings and the direction of movement thereof can be calculated.
