    Abstract: A process for dewatering sludges, which comprises performing a first stage agitation of the sludge to be dewatered during addition of a first high molecular weight flocculant developing in an aqueous solution an electric charge in polarity opposite to that of the sludge to effect neutralization of the electric charge of the sludge, conducting subsequently a second stage agitation of the sludge during a further addition of a second high molecular weight flocculant developing in an aqueous solution an electric charge in polarity opposite to that of said first flocculant to cause flocculation of the sludge and subjecting the so flocculated sludge to a dewatering operation, wherein a flocculant composed of a natural high molecular organic compound or a derivative thereof is used for at least one of said first and second flocculants with simultaneous employment of high power agitation for said first stage agitation, which process obtain a dewatered cake having low moisture content with efficient dewatering of the sludge.

    Abstract: A magnetic encoder is provided which can prevent a magnetized member from being separated from a fixed member to which the magnetized member is fixed under a severe temperature environment. The encoder includes a fixed member which is fixed to a rotating member and a magnetized member which is attached to the fixed member. The magnetized member, which is molded by mixing a magnetic powder in a resin, is bonded to the fixed member with a silicone resin based adhesive, and a thickness of an adhesive layer of the silicone resin based adhesive is 50 μm or more and 100 μm or less.

    Abstract: A magnetic encoder is provided which can prevent a magnetized member from being separated from a fixed member to which the magnetized member is fixed under a severe temperature environment.The encoder includes a fixed member which is fixed to a rotating member and a magnetized member 15 which is attached to the fixed member. The magnetized member 15, which is molded by mixing a magnetic powder in a resin, is bonded to the fixed member with a silicone resin based adhesive, and a thickness of an adhesive layer of the silicone resin based adhesive is 50 μm or more and 100 μm or less. In addition, an adhesive surface 17 of the fixed member with the magnetized member 15 is worked to be roughened.

    Abstract: A metallic foil and a transparent substrate film are laminated with an adhesive layer. The roughness of the adhesive-layer-side surface (lower surface) of the metallic foil is such that the maximum height Rmax is more than 0 and less than 4 &mgr;m. As long as the maximum height Rmax falls in the range, the adhesive layer never contains air bubbles in such sizes that reflectance is adversely affected. The roughness of the surface (upper surface) of the metallic foil, opposite the adhesive-layer-side surface, is preferably such that the arithmetic mean roughness Ra is between 0.02 &mgr;m and 1 &mgr;m. As long as the arithmetic mean roughness Ra is in this range, it is possible to efficiently conduct vacuuming to bring, into close contact, a photosensitive resin layer and a photomask in sheet form placed on the photosensitive resin layer, before effecting the pattern-wise exposure of the photosensitive resin layer.

    Abstract: An aperture grille, in which tensile strength applied on the aperture grille after it is mounted on a frame body is made uniform to eliminate rupture of grid and variations in elongation caused by heat. The width of each slit on a display surface side and a rear side of the aperture grille is constant in longitudinal direction, and the width of each slit on the display surface side is designed smaller on peripheral portion than at the central portion so that cross-sectional area of each grid of the aperture grille is made larger on the peripheral portion than at the central portion.
