Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To develop activity of a photocatalyst efficiently with respect to the quantity of light irradiated. SOLUTION: A catalyst body 2 formed into a photocatalytic film 21 on a base material 22 passing visible light and ultraviolet rays is arranged as a plurality of layers on the perimeter of a light source 3 irradiating the photocatalytic film 21. Moreover, the thickness A of the photocatalytic film 21 of another photocatalyst body 2 arranged at a farther position from the light source 3 is formed thicker as compared with the photocatalytic film 21 of the photocatalyst body 2 arranged at a closer position thereto. By such an arrangement, the light beam passing through the photocatalyst body 2 irradiates the other photocatalyst body 2. The photocatalytic film 21 of the photocatalyst body 2 arranged at the farther position supports a larger quantity of the photocatalyst, thereby preventing the catalytic function from being lowered even when the quantity of irradiated light decreases.

Filed: 1990-01-16
Abstract: PURPOSE:To facilitate correction for accurate display of height without moving an irrigation bottle to an upper or lower limit position by making a reference signal generating section emit a reference signal when the irrigation bottle is almost at an intermediate position of a moving range of a moving section to display a position of the irrigation bottle according to the control of a moving control section with a display section using an output of the reference signal generating section as reference. CONSTITUTION:A pulse enters a display section 56 from a movement control section 54. The display section 56 counts the number of the pulses. A displayed numeral of the display section 56 is corrected based on a signal as given when detection signals S1 and S2 are both high. While a wire 61 moves vertically, there is possibility that a deviation may be caused between an actual height of a bottle 51 and a displayed height of the bottle on the display section by elongation or other reasons. Or a displayed height may be deviated by holding and pulling the bottle 51 during stoppage. But the above-mentioned correction allows the deviation in the height of the bottle to be correct.
