Abstract: PURPOSE:To enable sure prevention of a collision accident of a moving body by selecting one of a plurality of different reference frequency values as a threshold value for determination of a dangerous relative speed in accordance with the length of a time from transmission to reception of an ultrasonic pulse. CONSTITUTION:When a timing control circuit 3 outputs a transmission gate signal for a prescribed time, a piezoelectric vibrator 5 transmits an ultrasonic wave to a following vehicle. At the same time, the circuit 3 selects the lowest one of reference frequency values stored 13, selecting higher reference frequency values sequentially as a time from transmission to reception of the ultrasonic wave becomes longer, and outputs the same to a comparator circuit 12. A reflected wave from the following vehicle enters a piezoelectric vibrator 7 for reception, and it is delayed by an input amplifier 6 and shaped 8 to be a rectangular wave. When the received wave reaches a stable level, a level detecting circuit 9 outputs this to a counter control circuit 10. The circuit 10 makes a counter 11 start counting and a counted value is outputted to the circuit 12. When this counted value is larger than the reference frequency values, a danger alarm signal is outputted to the following vehicle through an output register 14.

Abstract: PURPOSE: To prevent the occurrence of any hindrance in the outflow of filtrate despite some deviation of flexible sheets by expanding the surface opening parts of the filtrate holes of the core plates which flow out the filtrate through the holes of the flexible sheets superposed on the surface by providing specific recesses in combination.  
     CONSTITUTION: A pressure filter plate 1 for filter presses consists of a core plate 2 and a flexible sheet 3 coated with filter membranes on the front and back sides thereof.

Here, the holes 14 are formed slightly larger than the holes 12, and are further provided with recesses 15 inclining toward the holes 14 on the extension direction side of the sheet 3. Hence, when the sheet 3 elongates during the work, the holes 12 of the plate 7 deviates from right above the holes 14, but since they are still communicating with the recesses 15, the filtrate can flow out into the holes 14 by passing here.
