  • Patent number: 7999907
    Abstract: Exfoliation of an etching stopper is prevented. A color filter of the present invention includes an inorganic protection film (etching stopper) composed mainly of SnO2. Since the inorganic protection film as such not only has a high specific resistance but also has a linear expansion coefficient close to the linear expansion coefficient of a transparent electrode, the inorganic protection film is not exfoliated from the transparent electrode or the resin layer even if an object to be processed is heated. Since the inorganic protection film and the transparent electrode can be formed in the same film forming chamber, the time required to produce the color filter can be shortened as compared to in the conventional technique.

  • Publication number: 20110194517
    Abstract: When a transmission rate of each of lines that transmit data simultaneously between two STAs by using a plurality of radio channels and/or MIMO can be set independently, one data frame is fragmented in accordance with the transmission rates of the respective lines so as to generate a plurality of data packets having the same packet time length and data sizes equal to or smaller than a maximum data size. Those data packets are transmitted simultaneously by using a plurality of radio channels, or one radio channel and MIMO, or a plurality of radio channels and MIMO.

  • Patent number: 7974243
    Abstract: In retransmission processing due to a failure of transmission of data packets, a plurality of data packets are simultaneously transmitted between two STAs by utilizing multiple wireless channels and MIMO, and the number of idle channels and the number of retransmission packets are compared. Then, when both of the numbers are different or only when the number of idle channels is larger than the number of retransmission packets, the retransmission packets are reconstructed according to the number of idle channels, and the reconstructed retransmission packets are simultaneously transmitted by using the idle channels.
