Title: Optical pickup device
Inventor: IKENAKA KIYONO
IPC: G11B7/1275
Filed: 2004-08-04
Abstract: An optical pickup device for reproducing and/or recording information from/on first to third optical information recording media having protective substrate thicknesses t1 to t3 by using light beams with wavelengths lambda1 to lambda3 emitted from first to third light sources. The optical pickup has objective optical elements each having a diffraction structure provided at least on one optical surface and arranged in the optical paths of the first and third light beams. Among the diffracted lights generated when the diffraction structure imparts a phase difference to the light beam of wavelength lambda1, the first main diffracted light has a maximum diffraction efficiency E1 of 90% or more. The diffraction order n1 of the first main diffracted light is an odd number. The relation between the output power PW1 of the first light source and the output power PW3 of the third light source is expressed by PW1<PW3.

Title: Zinc oxide-based multilayer structural body and its producing method
Inventor: OHASHI NAOKI
IPC: H01L29/772
Filed: 2004-08-19
Abstract: [PROBLEMS] When zinc oxide semiconductor is used for an electric element, it is effective particularly to cause charge separation by comprising zinc oxide crystals of different states. [MEANS FOR SOLVING PROBLEMS] A zinc oxide-based multilayer structural body composed of a zinc oxide layer having a lattice volume Va and a donor concentration Na or a zinc oxide sold solution layer and a zinc oxide layer having a lattice volume Vb and a donor concentration Nb or a zinc oxide solid solution layer. The lattice volumes Va and Vb satisfy the relation VaNb. The zinc oxide layer having the lattice volume Va serves as a charge supply layer, and the zinc oxide layer having the lattice volume Vb serves as a charge acceptive layer. The zinc oxide- based multilayer structural body is characterized in that even while no electric field is applied from outside to the multilayer structural body, a state that charges move from the layer serving as the charge supply layer into the layer serving as the charge acceptive layer is established, and a depletion layer is formed in the charge supply layer because of this charge movement.

Title: Digital image enhancement
Inventor: STENTIFORD FREDERICK WARWICK M
IPC: G06T5/00
Filed: 2004-12-01
Abstract: Picture elements of a digitally coded image are each represented by a colour value. The value of an element is adjusted by firstly making a number of comparisons between the element and elements y elsewhere in the image. This comparison involves comparing a first picture element group (which comprises the picture element x under consideration and at least one further picture element in the vicinity thereof) with a second picture element group. The second picture element group comprises a base picture element y and at least one further picture element, the number of picture elements in the second group being the same as the number of picture elements in the first group and the position of the or each further element of the second group relative to the base picture element of the second group being the same as the position of the or a respective further element of the first group relative to the picture element under consideration. The comparison determines (114) whether the two groups match in the sense that they meet a criterion of similarity. When at least one comparison results in a match, a replacement colour value for the picture element under consideration is generated (116), as a function of the colour value for the base picture element of the or each second group for which a match was obtained.
