Abstract: A dish washing method includes a process for applying a sticking inhibitor to the surface of dishes in order to make it easy to remove food from the surface of the dishes. The sticking inhibitor is a compound having hydrophilic and hydrophobic groups. The compound is absorbed to the surfaces of the dishes by the hydrophilic groups, and is absorbed to food surfaces by the hydrophobic groups. The compound is a compound containing a fluoroalkyl group. Also, a dish washer has a reservoir for storing therein the sticking inhibitor and a passageway for joining the sticking inhibitor with a detergent.

Abstract: A blow-off duct is rotatably mounted on an air-conditioner. A human body detection device is provided at the blow-off duct in order to detect the presence of a person to be air-conditioned and then to identify the moving direction thereof. Comfortable localized air-conditioning can be realized since a wind direction control device controls a duct drive device of the blow-off duct in response to a human body detected signal and movement signal outputted by the human body detection device, and thus rotating the blow-off duct in accordance with the movement of the person to be air-conditioned.

Abstract: An automatic dishwasher which comprises an enclosure for accommodating articles to be washed, a washing solution tank arranged below the enclosure, a hot water storage tank for containing a predetermined amount of hot water for rinsing use, a plurality of nozzles for spraying a liquid medium towards the articles in the enclosure, a motor-driven pump, a first piping connecting a discharge port of the pump with the nozzles, a second piping connecting both of the solution and storage tanks with a suction port of the pump, and a valve assembly disposed on the second piping and operable to close a first passage between the suction port and the storage tank and to open a second passage between the suction port and the solution tank during the washing operation in which the articles are washed, and to open and close the first and second passages, respectively, during the rinsing operation in which the articles are rinsed.

Abstract: A ice making machine having a plurality of novel ice making plates or more preferably cylindrical ice making plates, which is formed to be longitudinal cell type wherein said ice making plates proper can be integrally fabricated by extrusion or drawing of heat conductive material, to have a means of fixing cooling tubing thereto by expanding, to be constructed said ice making plates proper and distance pieces made of heat insulating material being piled up alternately upon each other, to be constructed said cooling tubing being fixed thereto by expanding and thus to be assembled ice making plates having a predetermined size and number of ice cube making chambers therein.
