According to the regeneration process, the etching solution with a silicon compound contained therein is taken out of the etch bath. Water is then added to the taken-out etching solution to lower a concentration of phosphoric acid in the etching solution to 80 to 50 wt. %. By the lowing of the concentration of phosphoric acid, the silicon compound is caused to precipitate. The thus-precipitated silicon compound is removed from the etching solution. An etching process making use of the regeneration process and an etching system suitable for use in practicing the regeneration process and etching process are also disclosed.Type: GrantFiled: September 15, 2003Date of Patent: July 3, 2007Assignee: m·FSI Ltd.Inventors: Nobuhiko Izuta, Mitsugu Murata

Patent number: 7238296Abstract: When the entire amount of conductive metal mixed powder made of copper, manganese, and germanium is 100 parts by weight, the metal mixed powder is formed by mixing 4.0 to 13.0 parts manganese by weight, 0.2 to 1.4 parts germanium by weight, and 85.6 to 95.8 parts copper by weight, and 0 to 10 parts glass powder by weight and 0 to 10 parts copper-oxide powder by weight are mixed relative to the entire amount (100 parts by weight) of these metal components. The obtained resistive paste is then baked, and the resistive composition having the low resistance value and low TCR may be obtained. In addition, a resistor is made by forming the resistive element upon a substrate.Type: GrantFiled: August 25, 2003Date of Patent: July 3, 2007Assignee: KOA Kabushiki KaishaInventor: Satoshi Moriya

Patent number: 7238299Abstract: Disclosed are heat transfer fluids which possess a highly desirable and unexpectedly superior combination of properties, and heat transfer systems and methods based on these fluids. The heat transfer fluid comprise from about 30 to about 70 percent, on a molar basis, of carbon dioxide (CO2) and from about 30 to about 70 percent, on a molar basis, of hydrofluorocarbon (HFC), preferably HFC having one to two carbon atoms, and even more preferably difluoromethane (HFC-32). The preferred fluids of the present invention have a vapor pressure of at least about 100 psia at 40° F. and are also preferably not azeotropic.Type: GrantFiled: November 1, 2002Date of Patent: July 3, 2007Assignee: Honeywell International Inc.Inventors: Ravjiv R. Singh, Hang T. Pham, Martin R. Paonessa

Patent number: 7238300Abstract: A method comprises subjecting ant oxygen scavenger to actinic radiation; and then optionally storing the oxygen scavenger in a container, the container configured such that the oxygen scavenger exhibits no substantial oxygen scavenging activity while inside the container. The dosed oxygen scavenger can later be removed from the container, if stored therein, subjected to a second dose of actinic radiation to trigger the oxygen scavenger, and used in packaging oxygen sensitive products. A stored oxygen scavenger, untriggered, is also disclosed.Type: GrantFiled: October 10, 2003Date of Patent: July 3, 2007Inventors: James A. Solis, Richard Dayrit, Scott W. Beckwith, Brian L. Butler, Ronald L. Cotterman, Drew V. Speer, Thomas D. Kennedy
