  • Patent number: 6839223
    Abstract: Disclosed is an aluminum electrolytic capacitor, wherein each of anode and cathode foils is joined to a corresponding portion of a leader line through at least two caulked joint sections formed at each of the opposite ends of the flat portion, and a plurality of pressure-welded joint sections formed between the respective caulked joint sections at the opposite ends. The chaulked joint sections formed at each of the opposite ends of the portion provide a high joint strength. Further, the pressure-welded joint sections formed between the respective caulked-join sections at the opposite ends of the portion allow an electrical connection between the foil and the leader line to be stably obtained at a low resistance. This joint structure can, therefore, be applied to small-size capacitors which have not been able to be obtained by using only caulked joint, to achieve an aluminum electrolytic capacitor having a sufficient joint strength and a highly reliable electrical connection.

  • Publication number: 20040190056
    Abstract: An image processing apparatus which processes input image signals in real time. A plurality of image signals are input via input terminals. An external storage device stores a plurality of kinds of procedures for processing to be performed on image signals. A JOG dial specifies at least two kinds of procedures among the stored plurality of kinds of procedures, and enables the specified procedures and a procedure between the specified procedures to be arbitrarily changed and specified. When the procedure between the specified procedures is specified using the JOG dial, a CPU generates the specified procedure by interpolating the specified procedures, and carries out real-time processing on image signals for corresponding channels among the image signals for the plurality of channels according to the generated specified procedure.

  • Publication number: 20040189878
    Abstract: A video signal processing apparatus 1 and a video processing parameter setting apparatus 2 comprise a video processing apparatus (visual mixer). A parameter value collectively specifying portion 3 specifies in accordance with the order stored in an arpeggiator pattern memory 7, sets of scene data which collectively specify values of a plurality of parameters stored in a scene data memory 6. A changing process portion 4 changes in a given length of time, the values of video processing parameters from the values currently set on the video signal processing apparatus 1 to the parameter values collectively specified as a set of scene data. The changing process is started at a timing corresponding to a change time and completed at a subsequent switch timing. As a result, the video processing apparatus allows for collective specification of parameters with simple operations and smooth switching between video images at the changing of parameter values.
