Title: Sterilization of sandbox
Inventor: NONOYAMA NOBORU
IPC: A01N59/16
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a sterilization method of sandboxes capable of inexpensively sterilizing sandboxes without adverse effect to the human body and anxiety washed away by rain. SOLUTION: This sterilization is carried out by spraying a suspended solution prepared by mixing powdery grains of titanium oxide (TiO2 ), water, an alcohol and an inorganic binder on sand in sandboxes when bacteria containing Escherichia coli in the sandboxes are sterilized. By this process, innumerable titanium oxide grains which are contained in the suspended solution flow from the upper part of sand in the sandboxes into the inside and adhere to sand grains as the alcohol content is volatilized. When the titanium oxide grains once adhere to the sand grains, it is difficult to peel off the titanium oxide grains from the sand grains. Therefore, the titanium oxide grains are not moved downward by rain do not flow out from the sandboxes to be washed away from the sandboxes.

Filed: 1983-11-01
Abstract: PURPOSE:To obtain easily the Fourier coefficient of a high frequency signal by providing an analogue multiplying circuit and a circuit which converts this output voltage to a current, and integrating this current then detecting high-frequency components of a vieeo signal. CONSTITUTION:A video signal Vi which is outputted from an image pickup board 2, is added to an analogue multiplying circuit 4 and a signal generating circuit 10 through an image amplifier circuit 3. The signal generating circuit 10 uses a synchronizing pulse in the video signal as a reference,and generates a high-frequency signal Vs which becomes the reference. As a result, the product of the high-frequency signal Vs and the video signal Vi is obtained in the analogue multiplying circuit 4. After the output voltage of the analogue multiplying circit 4 is volt-ampere-converted, the output voltage is held in a certain period through an integrating circuit 6 and a sample hold circuit 7. This holding voltage is digital-converted by an A/D converter 8, and is sent to a CPU9. However, the above-mentioned digital quantity is in proportion to the high-stage Fourier coefficient in correspondence to the high-frequency components of the video signal, and therefore, the focus adjusting is executed by controlling a motor 13 so that the digital quantity will alwyas converge to the maximum value.
