  • Light source module
    Patent number: 8547502
    Abstract: It is to provide a light source module capable of downsizing an edge-light type backlight in thickness and reducing the usage amount of resin. A method of manufacturing a light source module includes a process of preparing a substrate with a first reflector including a reflecting surface mounted thereon, a process of mounting a plurality of light emitting elements on the substrate, a process of mounting a wiring board having an electrode on the substrate, a process of connecting the electrode of the light emitting element and the electrode of the wiring board with metal wire, a process of mounting a second reflector having a reflecting surface on the wiring board, and a process of filling the space between the first reflector and the second reflector, with resin.

  • Aluminum electrolytic capacitor
    Patent number: 6307733
    Abstract: An aluminum electrolytic capacitor includes an anode sheet of aluminum, a cathode sheet of aluminum, and separators disposed to sandwich either the anode sheet or the cathode sheet. Anode lead tabs of aluminum are connected to the anode sheet by “needling” or welding. Cathode lead tabs formed of an aluminum sheet are connected to the cathode sheet by “needling” or welding. The surface of each of the cathode lead tabs contacting the separator is roughened. Alternatively, an aluminum thin sheet may be disposed to overlie each of smooth-surfaced cathode lead tabs, with its surface contacting the separator roughened.
