Abstract: A washing machine has a partial washing apparatus, which has a supersonic resonator, which is driven by an oscillator to generate supersonic vibration and a supersonic vibration horn. A washing liquid is fed to the partial washing apparatus so as to be agitated by supersonic waves, which are then fed to an article to be washed to achieve partial washing of the article. The partial washing apparatus is detachably fitted to the washing machine proper at approximately the center of a lid of the washing machine proper. The partial washing apparatus may be used as a handy-type partial washing apparatus when held at a grip portion of the partial washing apparatus.

Abstract: A polluted water purifier for collecting a pollutant present in polluted water by flocculating the pollutant with a flocculant has a mixer 5 for mixing the polluted water with the flocculant F and air, an agitator 18 for agitating the polluted water, containing the flocculant F and the air, that flows into a cylindrical agitation chamber 6 along the inner surface thereof by making the polluted water into a spiraling stream so that the flocks formed by the flocculant F hold bubbles, and a separator 10 and 19, connected to the agitator 18, for temporarily storing the polluted water and for separating the flocks holding the bubbles.

Abstract: A self-cleaning coating film is formed using a self-cleaning coating composition including an oxidation, catalyst mixed within a composition including silicone synthetic resin and an organic solvent. The oxidation catalyst includes at least one element selected from a metal such as a noble metal and a metal oxide such as manganese dioxide, copper oxide, iron oxide, nickel oxide, chrome oxide, and the like. The metal is blended with a powder made of alumina, or the like, in the range of about 0.1 to 1.0 weight %. The diameter of the particles of the powder is on the order of about 40 to 300.mu.. The powder is mixed with the composition in the range of about 5 to 100 weight %. The metal oxide is present in the composition at about 50 weight %. The self-cleaning coating film is formed at about 40 to 300.mu. thickness. The thus formed self-cleaning coating film is exposed to an elevated temperature of about 300.degree. to 400.degree.

Abstract: A solar heat collector assembly includes a base carrying one or more heat collectors, a top cover of a "U" shaped configuration and a groove structure for joining the top cover to the base. The top cover in its preferred form is made of plastic material having a number of air cavities serving as heat insulators and the base is made of a heat insulating material, so that the heat collectors on the base are completely environed within a heat insulating chamber for good and efficient heat collection. Furthermore, the groove structure is designed to inhibit ingress of water into the groove structure and prevent ingress of water into the heat collectors in the event that water enters into the groove structure. A typical shape of the groove members is an "S" shape having an upward groove and a downward groove.
