Title: Photodetecting circuit
Inventor: SATO KOICHI
IPC: H03F3/68
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a photodetecting circuit which can be suitably used as a wireless headphone or the like and which can prevent a composite output signal from suffering a loss even when a plurality of photodetectors are disposed isolatedly from each other. SOLUTION: A plurality of photoelectric converters respectively receive light signals and convert the signals into electric signals, and output the signals to output terminals. The output terminals of the photoelectric converters are connected to a common connecting point, and the output signals of the respective converters are combined. The signal of a predetermined frequency is extracted from the combined output signal via a filter circuit. Since the output signals of the converters are output from the drain terminals of source grounding circuits, a transmission loss between the converters and the filter circuit can be reduced.

Title: Method of leaching copper from copper sulfide ore
Inventor: MURATA MASATERU
IPC: C22B11/00
Filed: 2001-11-14
Abstract: PROBLEM TO BE SOLVED: To efficiently leach copper ore with a sulfuric acid solution in a short time. SOLUTION: Copper in copper sulfide are can be leached into a sulfuric acid solution using a solution in which iron oxide and/or iron hydroxide are coexist. When iron oxide or iron hydroxide coexists in a sulfuric acid solution, iron in a solid dissolves, and is converted into Fe<3+> ions. This Fe<3+> ions work as an oxidizer, and dissolve the copper ore, and are simultaneously converted into Fe<2+> ions. The Fe<2+> ions are again oxidized into Fe<3+> ions by dissolved oxygen through the catalytic action of iron oxide or iron hydroxide and copper ions in the solution.
