Title: Method and apparatus for protecting pressure-sensitive part of pressure detection type water level gauge
Inventor: YAMAUCHI TSUNEO
IPC: G01F23/14
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To prevent a foreign article from adhering to a pressure sensitive part and maintain the function of the pressure sensitive part long, by covering the pressure sensitive part set at an upper part of a container opened at a lower part thereof with a liquid of a small specific gravity. SOLUTION: A pressure sensitive part 110 is set at an upper part of a container. A decoding cable 140 consisting of a vent pipe, a power source plug.signal line is fitted so that the pressure sensitive part 110 balances with an atmospheric pressure. A neck part 120 is formed at the container to narrow a central part, thereby preventing mud or foreign articles of a large specific gravity in the down water from being in touch with the pressure sensitive part 110. When the container is formed slim and the neck part 120 is further narrowed, the mud and foreign articles are more difficult to be in touch with the pressure sensitive part 110.  Furthermore, if a heater is set above the neck part 120 in the container to warm the water, a specific gravity of the water is reduced, so that the water of the smaller specific gravity rises along a side face of the container and stay in the periphery of the pressure sensitive part 110. Accordingly, the mud and foreign articles of the large specific gravity in the water do not adhere to the pressure sensitive part 110.

Abstract: PURPOSE:To enable automatically moving cursor to a desired direction and stopping at an arbitrary position with a simple operation by automatically scrolling the measured waveform indicated on a display when the cursor reaches the end of the frame of the display. CONSTITUTION:Every time a cursor moves for moving resolution set in advance, a new cursor position on all measured data stored in a memory 1 is calculated. Then, it is confirmed if or not, the new cursor position is within the frame of the display. If it is out of the frame, the frame is moved along the direction of the cursor movement and an indicated waveform is scrolled. By this, the measured data of waveform is indicated on the display for the new indication range. After that, a cursor image 6 is produced. On the other hand, if it is within the frame range, the cursor image 6 is produced without moving the frame. This image 6 is overlapped with a waveform image produced separately and displayed synthetically.
