Abstract: <P>PROBLEM TO BE SOLVED: To establish communication efficiently by suppressing communication delay regardless of packet size, and to eliminate the problem of hidden terminal.  <P>SOLUTION: A STA quantity holding section 107 counts the number of other STAs in the same cell by a signal received from an STA determination section 105. A backoff setting section 108 stores a table corresponding to the number of STAs in the cell or a calculation formula of offset value, and sets a backoff value by selecting or calculating a corresponding backoff value by using the number of STAs of the information of registered number of terminals in the cell. A packet generating section 109 generates a packet containing the information of the number of terminals and transmission data. A transmission standby section 112 sets a transmission standby time for standing by for transmission by the backoff value, stands by for transmission of the packet for the transmission standby time, and outputs the packet after the transmission standby time elapses.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of three-dimensionally displaying an image and a moving image without providing an external optical element and preventing the device from being upsized and complicated, and to provide a display method and an electronic apparatus.  <P>SOLUTION: In a region 13p, liquid crystal molecules are oriented in a first direction when a driving voltage is applied thereto, and in a region 13q, liquid crystal molecules are oriented in a second direction when a driving voltage is applied thereto, thus two kinds of light rays different in distribution of brightness can be emitted form a display region 12. When respectively different driving voltages are applied to the region 13p and to the region 13q, light rays with mutually different colors, brightness, and so on are respectively emitted from the region 13p and the region 13q. In the region 13p and in the region 13q, the liquid crystal molecules are oriented to mutually different directions, and light from the region 13p enters for example into a right eye of an observer and light from the region 13q enters for example into a left eye of the observer, and consequently both eyes of the observer recognize light rays with mutually different colors and brightness.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Title: Charger of secondary battery
Inventor: SUZUKI KENICHI
IPC: H02J7/10
Filed: 2005-07-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a charging system for reducing a fluctuation between cells in a secondary battery and acquiring the maximum charging efficiency.  <P>SOLUTION: The charging system uses a special pulse charging system. Since a pulse waveform contains a high-frequency component publicly known, a capacitance C of an electric double layer capacitor in the battery presents a low impedance in proportion to 1/2πfC. Since f is a frequency of the high-frequency component, the impedance becomes lower as the capacitance C becomes higher, and a current having the high frequency f easily pass. Since an electromotive force E is easily charged, the fluctuation between the charged cell is overcome, and a rise of the pulse waveform becomes moderate.  <P>COPYRIGHT: (C)2007,JPO&INPIT
