    摘要: This invention employs a scheme to extract, from components within a plurality of blocks obtained by subdividing an input signal with respect to time and frequency, every respective blocks, a component or plural components in order of magnitude of components within the respective blocks to determine, on the basis of a difference between magnitudes of components of respective blocks except for the extracted components and magnitudes of the extracted components, a bit allocation ratio to the respective blocks to quantize components of respective blocks on the basis of the bit allocation ratio thus to generate compressed data, thereby making it possible to realize a technique of allocation of bits desirable also from a viewpoint of the auditory sense with respect to such an input signal including, e.g., overtone to much degree. Accordingly, it is possible to carry out efficient compression/expansion of high sound quality from a viewpoint of the hearing sense. In addition, data recording medium adapted for recording therein data compressed by the digital signal processing apparatus of this invention can more effectively utilize memory capacity as compared to the conventional data recording medium.

    摘要: Pluralities of estimated desired and interference signal sequence candidates corresponding to the states of transition of desired and interference signals estimated to receive are sequentially generated in a state estimation part 40, from which they are provided to a desired signal estimation part 10 and an interference signal estimation part 20. These estimation parts 10 and 20 generate estimated desired and interference signals from the sequence candidates in accordance with conversion parameters from a channel parameter estimation part 50. A signal of their sum is subtracted in an error estimation part 30 from a received signal to yield an estimation error signal .epsilon.. The state estimation part 40 estimates estimated desired and interference signal sequences for the generated sequence candidates.

    摘要: A ratchet 3 is secured to a rotatable base plate structure 2 of an arm rest device 20. A Y-shaped pawl member 7 is pivotally attached to a stationary plate 6 by a pivot shaft 14 and a toggle spring 8. The stationary plate 6 includes a proximal end portion fitted over a fixation shaft 5. A tooth pawl 13 formed in one end portion of the Y-shaped pawl member 7 is engaged with a row of serrated teeth 10 of the ratchet 3 within a predetermined extent (from point A to point B) of pivotal movement of the base plate structure 2, by reason of urging load P from the toggle spring 8. Thus, the arm rest body 18 is fixed at a predetermined position. An engagement groove 32A in the Y-shaped lever 32 prevents the arm rest body in an accommodated position from being pivoted in a forward direction.

    摘要: A liquid crystal display including row conductors and column conductors divided into odd conductor groups and even conductor groups. Each of the groups includes two or more adjacent conductors. A plurality of adjacent subpixels in a row direction and in a column direction form a single pixel. The adjacent subpixels in the single pixel are divided into a first subpixel group including adjacent subpixels arranged in the column direction and a second subpixel group including adjacent subpixels arranged in the column direction. The first subpixel group is connected to a first conductor of an odd conductor group and the second subpixel group is connected to a second conductor of the odd conductor group. An adjacent pixel in the row direction has a first subpixel group connected to one conductor of an even conductor group and a second subpixel group connected to a second conductor of the even conductor group. A row driver sequentially supplies row signals to the row conductor and column drivers connected to the column conductors supply data signals of one polarity to the odd conductor groups and data signals of an opposite polarity to the even conductor groups, and alternately change the polarity of data signals applied to the odd conductor groups and the even conductor groups every two or more rows in the column direction between one polarity and the opposite polarity.
