  • Patent number: 7745246
    Abstract: A light emitting device wafer is fabricated, having a light emitting layer section, composed of AlGaInP, based on a double heterostructure and a GaP light extraction layer disposed on the light emitting layer portion, having a first main surface thereof appearing on the first main surface of the wafer, so as that a P-rich off-angled {100} surface, having a higher existence rate of P atoms than an exact {100} surface, appears on the first main surface the GaP light extraction layer. The main first surface of the GaP light extraction layer is etched with an etching solution FEA so as to form surface roughening projections. Therefore, it provides a method of fabricating a light emitting device capable of applying surface roughening easily to the GaP light extraction surface having the {100} surface, off-angled to be P-rich, as a main surface thereof.

  • Patent number: 7734062
    Abstract: An action recognition apparatus acquires image data and outputs action information representing an action content of a human captured in the image data. The action recognition apparatus includes a face-portion specifying section, an acquisition section, a specifying section, and an information output section. The face-portion specifying section specifies a first image region including a face portion of the human from the image data. The acquisition section acquires skin-color information peculiar to the human from pixel values of the first image region. The specifying section specifies at least one second image region including a predetermined portion of a body of the human from the image data except for the first image region based on the skin-color information. The information output section outputs the action information representing the action content of the human based on position relation between the specified first image region and the specified second image region.

  • Patent number: 7633831
    Abstract: An operation control circuit carries out a first access operation upon receipt of a first access command during activation of a chip enable signal, and carries out a second access operation accessing a memory core in a shorter time than the first access operation, upon receipt of the next access command during activation of the chip enable signal. For this reason, two types of access operations whose access times differ can be carried out by receiving the same access command at the same access terminal. A dedicated terminal for distinguishing between the two types of operations does not need to be formed in a controller, etc., which accesses a semiconductor memory. Selective use of the first and second access operations improves the operation efficiency of the semiconductor memory. Consequently, the operation efficiency of the semiconductor memory can be improved without increasing the cost of a system incorporating the semiconductor memory.
