Patent number: 7253536Abstract: A water supply apparatus includes an apparatus body disposed in a flow passage for sucking water to an indoor facility and a power generation unit installed in the apparatus body. Further, the power generation unit further comprises a rotating shaft extended in a direction perpendicular to the water channel direction of the flow passage, and impeller installed on the rotating shaft and rotated by a water flow, a magnet rotated interlockingly with the impeller, and a coil arranged oppositely to the magnet, wherein the impeller forms blades in the radial outer direction and forms clearances allowing water to pass to the inside of the blades. Since the clearances are formed between the blades and the rotating shaft such a trouble that water flowing into the base ends of the blades obstructs the rotation of the impeller can be eliminated to increase a power generation amount by the power generation unit.Type: GrantFiled: March 29, 2004Date of Patent: August 7, 2007Assignee: Toto Ltd.Inventors: Hidefumi Fujimoto, Naoyuki Onodera, Kimihiro Nakayama, Makoto Hatakeyama, Kazuyuki Enomoto, Yukihiro Kudoh, Tatsuhiro Kuga, Satoshi Ishimaru

Patent number: 6966536Abstract: A flush valve device 20 of a flush toilet includes a flush valve body 22 connected to a city water source and an operation unit 50. The operation unit 50 has an operation button 63 and a flexible inner cable 71, which is part of a cable mechanism 70. The inner cable 71 is extended from a rear side to a lateral side of a toilet body 12 and is linked with the operation button 63. In response to a press of the operation button 63, the flush valve body 22 opens to make a supply of washing water flown into the toilet body 12. This arrangement desirably increases the degree of freedom in positioning of the flush valve body and the operation unit, enhances the operability of the flush valve device 20, and effectively facilitates installation of the flush valve device 20.Type: GrantFiled: November 8, 2001Date of Patent: November 22, 2005Assignee: Toto Ltd.Inventors: Kazuyuki Enomoto, Jyunichi Tani, Katsuhiko Nagano, Akihiko Koba

Patent number: 5843291Abstract: An electrolyzer for producing alkaline and/or acidic water by way of electrolysis of water. In order to remove scale such as calcium carbonate deposited on the electrodes of the electrolytic cell (36) during electrolysis, the control unit (166) operates a polarity reversal switch (186) at a predetermined timing to reverse the electric potential applied to the electrodes of the electrolytic cell (36). The control unit (166) includes means (190/192) for detecting the hardness of water and varies the duration of application of DC voltage of opposite polarity in accordance with the hardness of water. Hardness of water is preferably determined by detecting the electric conductivity of water. Time required for removal of scale is shortened.Type: GrantFiled: February 21, 1997Date of Patent: December 1, 1998Assignee: Toto Ltd.Inventors: Toshio Eki, Toshiharu Otsuka, Kazuyuki Enomoto, Tomohiro Nishi
