  • Patent number: 7903710
    Abstract: A nitride semiconductor light-emitting device wherein a substrate or nitride semiconductor layer has a defect concentration region and a low defect density region other than the defect concentration region. A portion including the defect concentration region of the nitride semiconductor layer or substrate has a trench region deeper than the low defect density region. Thus by digging the trench in the defect concentration region, the growth detection is uniformized, and the surface planarity is improved. The uniformity of the characteristic in the wafer surface leads to improvement of the yield.

  • Patent number: 7904007
    Abstract: A toner cartridge is a developer storage container for storing toner (developer) in a hollow cylindrical section that is driven to rotate on its axis so that the stored toner is discharged from an outlet. The cylindrical section has an inner circumferential surface provided with a plurality of liner protruding portions that extend in a direction tilted with respect to a rotation direction of the cylindrical section. Moreover, the toner cartridge includes a stirring member capable of moving in the cylindrical section so as to collide with the protruding portions. This makes it possible to stably supply a developer and to realize an inexpensive developer storage container whose size can be reduced.

  • Patent number: 7903355
    Abstract: A lens tube has two, first and second lenses (1, 2), a tubular lens frame (3) for holding the two lenses (1, 2), and three spacers (7) in contact with the opposite lens surfaces of the first and second lenses (1, 2). The spacers (7) are arranged so as to be in contact with curved surfaces of the first and second lenses (1, 2) and determine the distance between the first and second lenses (1, 2). The lens frame (3) has the same inner diameter between the first and second lenses (1, 2), and the spacers (7) are in contact with the inner wall of the lens frame (3). Since the lens frame (3) has the same inner diameter between the first and second lenses (1, 2), the first and second lenses (1, 2) are held with their centers perfectly aligned with each other.

  • Patent number: 7903519
    Abstract: In an information recording/reproducing device, a resting period (tm) is set to be constant regardless of a mark length of a recording mark and regardless of the number of divided recording pulses. Consequently, it is possible to provide an information recording device, an information recording method, and an information recording medium, each allowing formation of a recording mark with a uniform width by use of a low laser power and allowing reduction of the number of parameters for determining a recording waveform, when forming a long recording mark.

  • Patent number: 7903064
    Abstract: Based on each of video data repeatedly supplied to a pixel, a signal processing section generates video data (Dd) for an image display period to be supplied to the pixel and video data (Db) for a blanking period to be supplied to the pixel, and outputs the video data (Dd) and (Db) in a predetermined order. Further, when a gradation transition from a gradation indicated by previous video data (D(i,j,k?2)) supplied to the pixel to a gradation indicated by current video data (D(i,j,k)) supplied to the pixel indicates an increase in luminance, a generating circuit for a blanking period of the signal processing section outputs video data indicative of a gradation which is increased compared with a gradation indicated by gradation data for a blanking period in a steady state, the video data thus outputted being regarded as video data (Db(i,j,k?1)) for a blanking period. This allows for providing a display device capable of displaying moving images with high quality.

  • Patent number: 7903183
    Abstract: A display comprises a backlight (30, 45-48) and a spatial light modulator (1) such as a liquid crystal device for modulating light from the backlight (30, 45-48). The backlight has a light-output surface (45) with a first set of regions in the form of parallel evenly spaced strips (48). In a multiple-view mode of the display, these strips (48) emit light whereas the remainder of the output surface (45) is dark. In a single-view mode of operation of the display, the whole of the output surface (45) emits light substantially evenly across the display area of the modulator (1).
