Filed: 2002-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a facing in which interlayer bonding strength is increased without lowering a feeling of luminance and hiding properties because there is the problem that there is the facing, in which a printed or coated layer 2, in which scaly aluminum powder is dispersed, is formed for imparting a metallic- tone feeling of luminance and imparting hiding properties at a high degree but the internal cohesive force of the printed or coated layer 2 is low and interlayer bonding strength is not good and then a feeling of luminance and hiding properties are insufficient in the facing using a nacreous pigment in place of scaly aluminum powder.  <P>SOLUTION: Scaly aluminum powder in which at least one surface is boehmite-treated is used. Adhesive properties with a binder resin are improved by a chemical adhesion by a hydroxyl group introduced to a surface and an anchorage effect by fine irregularities generated on the surface by a boehmite treatment, and excellent interlayer bonding strength is revealed. Since the lowering of interlayer bonding strength due to an elongation is also reduced, the facing is also fitted to the application of a bending and a three-dimensional fabrication.  <P>COPYRIGHT: (C)2003,JPO

When charges are read out from the photosensor 104, the light shielding film 14 is used as a read-out gate electrode and a read-out voltage is applied thereto. Since the side 18 functioning as the gate electrode extends over the entire width of the read-out gate 130, the read-out voltage can be lowered as compared with the conventional one. Furthermore, a voltage is not applied to the read-out gate 130 at the time of transfer and a high voltage is not required to be applied to the transfer electrode at the time of reading out charges.  <P>COPYRIGHT: (C)2003,JPO
