A solid-liquid separation device includes a plurality of fixed members and movable members that are movably disposed between the adjacent fixed members, and a screw extending through the fixed members and the movable members in a state where the screw is not in contact with the fixed members and the movable members. The screw is rotationally driven about a center axis line thereof. A filtrate separated from an object is discharged to the outside of the solid-liquid separation portion through filtrate discharge gaps, and the object that has a reduced liquid content ratio is discharged from the outlet to the outside. In order to increase significantly a dewatering ratio, the movable members are formed to move while penetrating closer to the center axis line of the screw than an outer circumferential edge of the blade of the screw, without coming into contact with the screw.

The pattern line width of a coil is partially widened in a predetermined dimension and wiring patterns of a coil on the surface side and a coil on the rear side are arranged so as not to be in overlapped positions. Consequently, a direct current resistance of the coil can be reduced and an adverse influence by a self resonance of the coil on a communication can be reduced.

A method and device for decoding received coded image data for image compression in moving picture telecommunication, wherein data are subjected to discrete cosine transformed coded compression to enhance decoding processing performance. To reproduce high precision moving pictures, positional information within an image block is scanned by a run/level dividing device from run values of the received data composed of the combination of run values and level values. Each pair of run and level values are subjected to a reverse quantifying process to form pairs of position and level values wherein the positional information and the level values correspond to each other. The level values are transformed into positional information using the zigzag scan and are also reverse quantified. A reverse discrete cosine transforming device carries out processing of the reverse quantified data to decode the image data.
