  • Publication number: 20150156992
    Abstract: A method for producing poultry for raising poultry with high production score is provided. In a method for producing poultry in a poultry house, a feeding area for feeding the poultry is illuminated with blue light in an early raising period of a poultry raising period. In the early raising period, behavior of chicks can be restricted by illuminating the feeding area with blue light. Accordingly, sudden death of chick or metabolic disorder due to excessive and abrupt behavior of chick can be prevented, and thus chicks not having injury or diseases such as metabolic disorder can be raised, and physical conditions of the grown poultry can be improved.

  • Patent number: 6479840
    Abstract: Disclosed is an inventive diode which can reduce a stray capacity to improve various characteristics thereof, in which a dielectric layer, a conductive layer and a second dielectric layer are respectively formed by deposition in this order on an upper face of a semiconductor substrate excluding a central portion of an exposed surface of a P-type region. Then, an anode side electrode is formed extending from the exposed surface of the P-type region to the upper face of the second dielectric layer, and is electrically connected with the P-type region. Herein, the conductive layer is formed such that it is isolated from the electrode by the second dielectric layer, is connected with the semiconductor substrate upper face in a location where the dielectric layer has not been formed, and partially resides in a location sandwiched between the electrode and the semiconductor substrate.

  • Patent number: 6153921
    Abstract: Disclosed is a diode device in which two electrodes of regions forming both terminals are provided on the same face, thereby enabling the device to be connected to a circuit substrate by face-down bonding. Since a region is located within the semiconductor base, an electrode cannot be connected at the top face thereof; to overcome this, a groove is provided extending in a perpendicular direction from the top face of the semiconductor base to the region, and an electrode is provided in the groove. Then, the electrode in the groove is exposed at the top face, enabling the electrodes of both regions to be connected at the top face.

  • Patent number: 6074111
    Abstract: A digital still camera combines a display pattern received from a printing apparatus and a photographed image with each other, and displays the resultant image on a viewfinder. A user adjusts the balance between the display pattern and the image of the object both being displayed on the viewfinder, and depresses a shutter release button. The digital still camera fetches the photographed image. The digital still camera sends to the printing apparatus the fetched image and a pattern name specifying the display pattern used at the time of photographing. The printing apparatus combines the decoration pattern specified by the pattern and the image received from the digital still camera into composite image data. The printing apparatus prints the composite image data.
