Title: Level measuring apparatus
Inventor: TAKAYAMA TOMIO
IPC: G01C5/04
Filed: 1987-07-30
Abstract: PURPOSE:To determine the change in water level in real time and to measure the water level highly accurately, by arranging level sensors, wherein magnet floats are floated along magnetostriction type displacement gates, which are suspended from a top parts into tubular containers, so that the floats can be freely moved up and down, at a reference point and measuring points. CONSTITUTION:When water levels in tubular containers 1 in level sensors A at a reference static point (b) and measuring points 1-3 are fluctuated, magnet floats are moved up and down along magnetostriction type displacement gages 3. Thus the change in water level in each tubular container 1 is captured with the displacement gage 3. The detected level signal is sent to a measuring device C from a signal converter 2. Thus the level can be measured in real time in a dynamic way (level change response of about 60cm/sec). In said magnet float 4, a doughnut type float ring 5 is arranged at the outside of the float. When said float ring 5 is floated on the surface of the water, disturbance such as especially high frequency vibration is suppressed, and the measuring accuracy is improved.

Patent JP-H0477063-A (JP)
Title: Clip circuit
Inventor: KOYANO ATSUSHI
IPC: H04N5/20
Filed: 1990-07-16
Abstract: PURPOSE:To make a clip characteristic sharp and to eliminate the need for a variable gain amplifier by devising such a circuit that a transistor(TR) is turned on when a level of an input signal to an input terminal is larger than a voltage of a variable reference voltage source and the TR is turned off when smaller. CONSTITUTION:When a level of an input signal Vin reaches a clip voltage Vref or over, a TR Q3 is turned off and a TR Q4 is turned on. Thus, a current flows to a resistor R3, a voltage drop is caused and an L level is fed to a base of the TR Q2 via a TR Q5 to turn on the TR Q2, then the increase in the potential at a node N is limited. Thus, the potential of the node N is not increased over the clip voltage Vref. The node N, that is, the emitter of the TR Q2 reaches a low impedance at that point of time and the input signal Vin over the clip voltage Vref is divided by resistors R1, R2 and the result is outputted via a buffer amplifier 10. Thus, a gain G' after clipping is decreased more than the gain G before clipping.
