  • Publication number: 20080274409
    Abstract: A separator for alkaline batteries which is obtained by bonding 5.0 to 45.0 g/m2 of a highly hygroscopic macromolecular compound of the crosslinking type having carboxyl group to a wetlaid nonwoven fabric comprising an alkali-resistant fiber, followed by crosslinking the macromolecular compound, wherein a silicate compound is added to the highly hygroscopic macromolecular compound of the crosslinking type in an amount of 1.0×10?4 to 10 mg/cm2 per unit area of the separator. By adding the silicate compound, absorption of the electrolyte is increased, the electrolyte can be held for a long time, the electric resistance of the separator itself can be kept small, growth of dendrite can be suppressed, short circuit due to the formed dendrite can be prevented, the volume of the negative electrode material can be increased by suppressing the thickness of the separator after absorbing the electrolyte, impact of dropping can be endured, and oxidative degradation in the alkaline dry cells can be suppressed.

  • Patent number: 7447378
    Abstract: The present invention enables processing results which are more accurate and which have higher precision as to events of the real world to be obtained. (An inverse gamma correction unit 5001 applies inverse gamma correction to an input image wherein light signals of the actual world have been projected and a part of the continuity of the light signals of the actual world has been lost, and which has been subjected to gamma correction. A data continuity detecting unit 101 detects, in the input image subjected to inverse gamma correction, data continuity corresponding to the continuity of light signals of the real world. An actual world estimating unit 102 estimates the light signals by estimating the continuity of the light signals of the real world, based on the data continuity. An image generating unit 103 generates an output image from the estimated light signals.

  • Publication number: 20080212723
    Abstract: In a signal processing apparatus adapted to process a signal transmitted via a transmission path, distortion of a waveform of a signal value of a specific symbol is predicted on the basis of a characteristic of distortion depending on values of symbols transmitted before the specific symbol, and the distortion is removed from the waveform of the received signal thereby producing a distortion-removed waveform. A comparison value is calculated for each allowable value of the specific symbol by subtracting a predicted signal value of the specific value from the distortion-removed waveform. A symbol value corresponding to the smallest comparison value is determined as the value of the specific symbol. An error suspicion level value indicating the degree of suspicion of being incorrect is calculated for each of the predetermined number of symbols, and already determined values of symbols are corrected in accordance with the error suspicion level values.

  • Patent number: 7260260
    Abstract: An object of the present invention is to separate in real time a captured image into a foreground component image and a background component image. An image captured by an image-capturing unit 74 is separated into a foreground component image and a background component image, which are stored in an image storage unit 72. A billing processor 75 performs billing processing to charge fees for separating the image. A separating portion 91 performs motion-blur processing of the separated foreground component image and outputs the processed foreground component image and the background component image to a synthesizer 92. The synthesizer 92 combines the input motion-blur-processed foreground component image and the separated background component image to synthesize an image and displays the synthesized image on a display unit 73. The present invention is applicable to a camera terminal device.

  • Publication number: 20070180443
    Abstract: This invention relates to an information-signal-processing apparatus etc. for performing a series of processing pieces by using plural functional blocks in response to any information signals, in which functions can be easily upgraded through version upgrading of the functional blocks. Control block 110 issues a common command and transmits it to a control block 120 via a control bus 111. Control I/F 120 of the functional block 120 converts this common command into an intra-functional-block command if the common command is the common command related to its own functional block, and supplies the functional section 120e with it. This enables the functional block 120 to operate adaptively in accordance with the common command. When performing upgrade of the functions by the version updating of a predetermined function block, the common command need not be changed.
