  • Patent number: 7933527
    Abstract: In an image forming apparatus, an electrostatic latent image formed on a surface of a photoreceptor is developed into a toner image. A printing paper transported on a transport belt is brought into contact with the surface of the photoreceptor and an electric field is applied to the printing paper from a rear surface of the transport belt by a transfer roller to transfer the toner image onto the printing paper. The transfer roller applies different levels of electric field to the printing paper, so that a predetermined transfer electric field is applied to a region other than a leading edge of the printing paper being transported. An electric field weaker than the predetermined transfer electric field is applied to the leading edge. Even in the presence of a projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor.

  • Patent number: 7931396
    Abstract: A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A light guide receives the light from an edge surface and guides the light by total internal reflection. Groove structures which are located on at least one of the major surfaces of the light guide permit redistribution of light around obstacles that may be present within the light guide structure, thereby maintaining brightness uniformity of the backlight or illumination panel.

  • Patent number: 7932957
    Abstract: A receiver apparatus 3 has a digital circuit portion 13 that converts a compressed digital signal outputted from a digital demodulating portion 12 into digital video and audio signals and a video/audio output circuit 14 that converts the digital video and audio signals outputted from the digital circuit portion 13 into analog video and audio signals. With this configuration, a video/audio processing IC for digital signal processing no longer needs to be mounted on the circuit board of a video display apparatus 4, and thus a receiver system can be realized with a video display apparatus having a simple configuration.

  • Patent number: 7932915
    Abstract: A control section divides a single frame so that a ratio of a period corresponding to a latter sub-frame and a period corresponding to a former sub-frame ranges from 1:3 to 1:7. A divisional point of the frame is a point which allows each of the latter sub-frame and the former sub-frame to minimize a difference between an actual brightness and an expected brightness. The frame may thus be divided at the point where the difference is largest in the normal hold display, so that it is possible to minimize the difference at this point. On this account, it is possible to reduce the difference in a single frame substantially by half as compared with an arrangement for carrying out the normal hold display, and thereby suppress the excess brightness caused by the difference.

  • Publication number: 20110093921
    Abstract: This invention provides a multi-functional peripheral and a multi-functional peripheral control system that manage a total number of output sheets of a user strictly and accurately even when an authentication server of a multi-functional peripheral is not able to perform authentication due to network failure or the like and authentication and output limitation are performed in the multi-functional peripheral. When the number of outputtable sheets registered in a user information management table is not 0, the multi-functional peripheral executes a copy job. When the number of copy outputtable sheets becomes 0, or when copy output of all pages is completed, the number of output sheets is deducted from the number of copy outputtable sheets registered in the user information management table, and thereby the user information management table is updated. Then, when connection to the authentication server is restored, the authentication server updates a user information management DB.

  • Publication number: 20110089850
    Abstract: In a light emitting device, a P-type first region (506) and a P-type third region (508) are placed on both sides of an N-type second region (507) of a rod-like light emitting element (505). Therefore, even if connection of the first, third regions (506, 508) of the rod-like light emitting element (505) relative to the first, third electrodes (1, 3) is reversed, a diode polarity relative to the first, third electrodes (501, 503) is not reversed, making it possible to effectuate normal light emission. Thus, a connection of the first, third regions (506, 508) relative to the first, third electrodes (501, 503) may be reversed during a manufacturing process, making it unnecessary to provide marks or configurations for discrimination of orientation of the rod-like light emitting element (505), so that the manufacturing process can be simplified and manufacturing cost can be cut down.
