Publication number: 20030146369Abstract: A correlated double sampling circuit that reduces a shift in the potential of a node on the reference voltage side produced by reset operation. A reset signal RST is turned to “H” and then is turned to “L.” By doing so, a photodiode begins integration according to the intensity of light. This detected signal is sent to a CDS circuit. An SW1 and a connection switch for sampling in the CDS circuit are turned to ON to accumulate the detected signal according to integration time in C1 and C2 as electric charges. After a certain period of time elapsed, the SW1 and connection switch for sampling are turned to OFF to hold the detected signal sampled. Next, the RST is turned again to “H” and the SW1 is turned to ON. Then the RST is turned to “L” and the SW1 is turned to OFF. By doing so, reset noise is sampled and held in the C1. As a result, only a signal component can be extracted from the detected signal.Type: ApplicationFiled: January 2, 2003Publication date: August 7, 2003Applicant: Fujitsu LimitedInventor: Masatoshi Kokubun

Publication number: 20030146410Abstract: Foamed material composed of water and limestone or other mineral dust suspended in a pregenerated foam is applied to the surface of a mine. Dry limestone dust or mineral dust is blended with pregenerated foam or foam generated in situ to produce a mass of foamed material that is highly vesicular but that is cohesive enough to be sprayed as a foamed mass against mine wall surfaces and ceilings. The foamed material is applied with a spray device that allows it to adhere to the surfaces of the mine. In another embodiment a dry powder formulation containing limestone dust, dry powder foaming agent and an additive that promotes the production of gas which effervesces upon contact with water can be used. The dry powder formulation can be applied by mixing it with water during application or by applying it to a wet surface. The foamed material can be built to a thickness suitable for the prevention and suppression of fires caused by the ignition of coal dust and methane gas.Type: ApplicationFiled: June 21, 2002Publication date: August 7, 2003Inventors: Frank T. Gay, Dontave D. Cowsette, Jeffrey T. Champa, Bradley S. Hulvey

Publication number: 20030146411Abstract: Halophosphate luminescent materials co-activated with europium and manganese ions and having the general formula of (Ca,Sr,Ba,Mg)5(PO4)3:Eu2+, Mn2+ are disclosed. The inclusion of manganese shifts the peak emission to longer wavelengths and, thus, is beneficial in generating a bright yellow-to-orange light. White-light sources are produced by disposing a halophosphate luminescent material, optionally with a blue light-emitting phosphor, in the vicinity of a near UV/blue LED. Blue light-emitting phosphors that may be used in embodiments of the present inventions are Sr4Al14O25:Eu2+, Sr6P6BO20:Eu2+, BaAl8O13:Eu2+, (Sr,Mg,Ca,Ba)5(PO4)3Cl:Eu2+, and Sr2Si3O6.2SrCl2:Eu2+.Type: ApplicationFiled: May 21, 2001Publication date: August 7, 2003Inventors: Alok Mani Srivastava, Holly Ann Comanzo, Anant Achyut Setlur

Publication number: 20030146414Abstract: A method is disclosed for preparing cathodes loaded with manganese oxide that are suitable for use in metal-air cells. The manganese oxide is prepared from the reduction of potassium permanganate by sodium formate at a substantially neutral pH level to produce manganese oxide sols. The sols are then mixed with a carbon slurry to produce a colloidal suspension. The suspension is subsequently waterproofed before being filtered, washed, dried, and rolled to produce the active catalyst layer for the cathode during discharge of the cell. The catalyst layer is then laminated with a current collector and air diffusion layer. A separator is then added to provide a carbon-based air cathode loaded with manganese oxide.Type: ApplicationFiled: February 4, 2002Publication date: August 7, 2003Inventor: Ernest Ndzebet
