Abstract: A method of manufacturing a cake-shaped decorative accessory made of a towel by setting a mount, which becomes a framework for forming a towel cloth in a cake shape, on a towel cloth, and folding the towel cloth together with the mount into a cake shape. More specifically, a cake-shaped decorative accessory made of a towel is obtained by: setting a polygonal shape mount, which has a folding piece extending from each one of sides thereof, on a towel cloth which is larger than the mount; folding the towel cloth together with the folding piece of the mount to form a folded item; and placing the folded item in a cake cup with a top face portion of the mount facing above, thus forming the folded item into a cake shape.

Abstract: A cake-shaped decorative accessory made of a towel in a cylindrically shaped cup. The towel is inserted in a cylindrical shaped cup with the top portion of the towel protruding from the opening of the cup. The opening of the cup has a larger diameter than the bottom, and the protruding portion of the towel is formed into a dome shape. The towel is of a square shape with the four corners folded back in the same direction so that the four corners are at the center of the towel to form a double layer, the double layered towel is further folded back so that the four corners are at the center of the towel to form four layers in a square shape, a center portion of the four layered towel is expanded into a dome shape which upwardly protrudes out of the opening of the cylindrically shaped cup.

Abstract: A color image forming method and apparatus using larger microcapsules each of which contains a plurality of kinds of smaller microcapsules scattered within the larger microcapsule, reacting substances that are mixed with each other to perform a coloring reaction being scattered inside and outside the smaller microcapsule. A protective wall of each smaller microcapsule is broken with a corresponding predetermined ultrasonic stimulus depending upon color component information to thereby cause the reacting substances to diffuse with each other to perform a coloring reaction and hence image printing. The conditions for breaking the protective walls of the respective smaller microcapsules that contain a color former component vary from smaller microcapsule to smaller microcapsule, or are determined depending upon the outer shapes, materials and thickness of the protective walls of the smaller microcapsules.

Abstract: A water purifier 40 includes a flow meter 42 for measuring the cumulative flow of water through a water purification cartridge 6. The flow meter has an indicator portion 44 that rotates in response to increasing cumulative flow and a graduated portion 46 rotating about the same axis as that of the indicator portion. The graduated portion includes an insertion groove 29 for manually rotating the graduated portion in order to reset the flow meter. Because the flow meter has few part, the body of the water purifier can be made compact and its cost reduced.

Abstract: The water purifier according to the present invention is provided with a flow meter which measures the integrated flow of purified water through a water purification cartridge, and the flow display of the flow meter has an indicator portion which rotates with an increase of the flow, and a graduated portion which can rotate around the same axis as the indicator portion rotates around. In this water purifier, there is no flow meter which has a complex mechanism built in for measuring the flow, and resetting of the flow display can be performed easily and accurately. Therefore the main body of the water purifier can be made compact, and the amount of material and the number of parts comprising the water purifier and its cost can be reduced, it is possible to carry out a compact product and low cost.
