  • Publication number: 20100033755
    Abstract: An image forming apparatus and an image processing apparatus form N copies of image data that fit a single physical page of print medium. A data receiving section receives print data from an external apparatus. An image reducing section produces a first item of image data based on the print data by reducing a size of an image that corresponds to the print data by a factor of N, N being an integer greater than 1. An image data producing section produces a second item of image data containing N copies of the first item of image data, the N copies of image data fitting a single physical page of print medium. An image printing section prints the second item of image data on the single physical page of print medium.

  • Patent number: 6121540
    Abstract: A composite material substrate comprises a matrix material and a skeleton structure of a fibrous material. The matrix material exclusively participates in the thermal expansion of the substrate and the fibrous material in the mechanical strength thereof. The fibrous material constituting the skeleton structure has no influence on the thermal expansion profile of the matrix material, and the skeleton structure is loosely bonded to the matrix material at their interface. The substrate is used for solar cells. Photoelectric transfer layers of semiconductors are formed on the substrate to fabricate large-sized solar cells.

  • Patent number: 5324963
    Abstract: A light-emitting diode has a GaAs substrate, and two ZnSe layers formed on the substrate and having a pn junction. An AuZn electrode is formed on the upper one of the ZnSe layers with a (ZnSe).sub.x (GaAs).sub.(1-x) ohmic contact layer interposed therebetween. The coefficient x of the composition formula is substantially continuously varied from 1.0 to 0 from the ZnSe layer side. An AuGe electrode is formed on the lower surface of the GaAs substrate. The (ZnSe).sub.x (GaAs).sub.(1-x) layer reduces the resistance between the ZnSe layer and AuZn electrode, and also prevents Ga atoms from diffusing into the ZnSe layer.
