Abstract: <P>PROBLEM TO BE SOLVED: To reduce wasteful dissolution of antibacterial agents in drain water.  <P>SOLUTION: Drain water made to drop down from an indoor heat exchanger 7 is made to drop down to any position on a guide face 14c. For example, when the drain water is made to drop down to a position between the antibacterial agents ab adjacent to each other at the uppermost stage, in the dropping-down, the drain water does not come into contact with the antibacterial agent ab. Then, however, when the drain water is made to flow from that position toward the downstream side along the guide face 14c, the drain water includes an opportunity to come into contact with the antibacterial agent ab in the second row from the top. Thus, by arranging the antibacterial agents ab dispersedly to form a diced shape, the number of opportunities to make the drain water made to drop down to any position of the guide face 14c come into contact with the antibacterial agents ab is increased, and the drain water including the antibacterial agents ab is made to flow toward the downstream side.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To obtain an accurate liquid level by correcting the error of components in a mechanism for obtaining the liquid level in accordance with the position of a float by rotating a drum by detecting the tension of a wire suspending the float.  <P>SOLUTION: A control circuit detects an output value B of a sensor to a rotating angle A of the drum. For example, at the rotating angle of 90°, a correction line E connecting between known light and heavy outputs C, D is obtained, and for each rotating angle A, for example, for each 1°, the correction line E is obtained. Thus, to the obtained tension, a tension correction value F is obtained for each rotating angle, and an accurate tension of the measuring wire is obtained by correcting the sensor output on the actual measurement. By driving a motor using this sensor output, the rotation of the drum is controlled in accordance with the true value of the tension value.  <P>COPYRIGHT: (C)2010,JPO&INPIT
