  • Publication number: 20130082393
    Abstract: An upper surface of a plug (PL1) is formed so as to be higher than an upper surface of an interlayer insulating film (PIL) by forming the interlayer insulating film (PIL) on a semiconductor substrate (1S), completing a CMP method for forming the plug (PL1) inside the interlayer insulating film (PIL), and then, making the upper surface of the interlayer insulating film (PIL) to recede. In this manner, reliability of connection between the plug (PL1) and a wiring (W1) in a vertical direction can be ensured. Also, the wiring (W1) can be formed so as not to be embedded inside the interlayer insulating film (PIL), or a formed amount by the embedding can be reduced.

  • Patent number: 7769270
    Abstract: This invention realizes an editing system and control method thereof capable of significantly improving working efficiency of editing work. A proxy editing terminal device creates an EDL with low-resolution video/audio data, resulting in reducing time to create the EDL. Further, the low-resolution video/audio data and high-resolution video/audio data having the same contents and different resolutions are previously stored, so that the creation of a final edit list with the high-resolution video/audio data based on the EDL can be started in a short time after the EDL is created with the low-resolution video/audio data. Thus working efficiency of the editing work can be significantly reduced with reducing time to create the EDL and the final edit list.

  • Patent number: 7483644
    Abstract: An image forming apparatus including an AC high voltage power supply, a DC high voltage power supply, and a high voltage power supply apparatus, which outputs an output voltage at an output end by superposing an output of the AC high voltage power supply and an output of the DC high voltage power supply. The high voltage power supply apparatus has a positive peak detector detecting a positive peak of the voltage at an output end, and a negative peak detector detecting a negative peak of the voltage at an output end. An output voltage of at least one of the AC high voltage power supply and the DC high voltage power supply is controlled on the basis of the detection result of at least one of the positive peak detector and the negative peak detector.

  • Patent number: 7424202
    Abstract: An editing system and a control method for improving efficiency of editing work. The editing system is provided with a server for storing the video data of edit material. A memory stores the video data read from the server, the memory having accessibility faster than the server. An editing terminal for reading, processing, and editing required video data from the memory based on an edit list stored in a selected file. When opening the selected file, the editing terminal makes the server read the video data required for creating the edited video based on the edit list being stored in the file and makes the memory store and keep the video data.
