Patent number: 8878351Abstract: A semiconductor device having a chip-on-chip structure is constituted of a first semiconductor chip and even-numbered pairs of second semiconductor chips, all of which are laminated together on the surface of an interposer. The first semiconductor chip controls each pair of the second semiconductor chips so as to activate one second semiconductor chip while inactivating another second semiconductor chip. The second semiconductor chips are paired together in such a way that through-vias and electrodes thereof are positioned opposite to each other via bumps. Since drive voltage electrodes supplied with a drive voltage (VDD) and reference potential electrodes supplied with a reference potential (VSS) are mutually connected together between the paired second semiconductor chips, it is possible to increase the overall electrostatic capacitance of each second semiconductor chip so as to substantially reduce feed noise without increasing the overall layout area of the semiconductor device.Type: GrantFiled: January 6, 2009Date of Patent: November 4, 2014Assignee: PS4 Luxco S.A.R.L.Inventors: Eiichi Suzuki, Hideki Osaka, Yutaka Uematsu, Yoji Nishio

Publication number: 20100163468Abstract: It is an object of the invention to provide a optimized rational water treatment technique for chemically treating water to be treated. A representative water treatment apparatus is adapted for chemically treating water by using chemicals. In a water treatment apparatus, a disinfectant within a chemical cartridge dissolves out in water to be treated in a disinfecting chamber so that the water is disinfected. Further, a magnet is disposed within the chemical cartridge. The accommodated position of the magnet within the chemical cartridge is changed according to the remaining amount of the disinfectants. The magnetism of such magnet is detected by a magnetic sensor disposed on the outside of the chemical cartridge, so that information on consumption of the disinfectant can be detected.Type: ApplicationFiled: June 27, 2008Publication date: July 1, 2010Applicant: Fuji Clean Co., Ltd.Inventors: Eiichi Suzuki, Yukio Doi, Jun Hibino, Hiroshi Yamashita

Patent number: 7622042Abstract: It is an object of the invention to provide an effective technique for detecting the quality of water with high accuracy. A representative water treatment apparatus includes an aerobic treatment region that treats water aerobically, a downstream region in which the water aerobically treated in the aerobic treatment region flows, a water quality sensor that is submerged in the downstream region and detects the water quality and a sensor washing arrangement that washes the water quality sensor by supplying the water of the downstream region to the water quality sensor at a flow rate higher than water flowing around the water quality sensor. As a result, sludge generated due to aerobic treatment can be prevented from being deposited on the water quality sensor and/or deposited sludge can be removed, so that the accuracy of water quality detection of the water quality sensor can be enhanced.Type: GrantFiled: October 22, 2008Date of Patent: November 24, 2009Assignee: Fuji Clean Co., Ltd.Inventors: Eiichi Suzuki, Yukio Doi, Hayato Kurokawa, Yosuke Tabata, Toshiyuki Iwama
