  • Publication number: 20090322779
    Abstract: A display device is designed to conduct a display operation using a number n of primary colors (where n is a natural number that is equal to or greater than four). The display device includes a video signal converting section that receives an m-primary-color signal representing a number m of primary colors (where is m is also a natural number that is smaller than n) and that converts the m-primary-color signal into an n-primary-color signal representing the n primary colors. The n primary colors include a color that is complementary to a particular one of the m primary colors. The video signal converting section generates the n-primary-color signal such that if a color component representing the particular primary color of the m-primary-color signal has a negative level, the complementary primary color has an increased luminance and the other non-complementary primary colors have decreased luminances compared to a situation where the color component representing the particular primary color is zero.

  • Publication number: 20090326728
    Abstract: A method for controlling power usage on a device is described. A job is received at a device. The job is classified as an on-demand job or as a non-on-demand job. The job is placed on an on-demand job queue if the job is an on-demand job. The job is placed on a non-on-demand job queue if the job is a non-on-demand job. The on-demand job queue is processed. The non-on-demand job queue is processed only during an off-peak period.

  • Publication number: 20090324297
    Abstract: A toner cartridge, and a process unit and image forming apparatus using the same. Toner contained in an outer chamber is scooped with a toner scooping member by rotation of a toner container and slides down toward a communication port along an upper surface of a partition, and falls down to an inner chamber from the communication port. Then, the toner that has fallen down into the inner chamber from the communication port slides down toward a toner discharging port along the inner surface of the partition, and is discharged from the toner discharging port. Furthermore, toner discharged form the toner discharging port is discharged from a toner through hole provided in a toner container supporting member to the outside of the toner cartridge.

  • Patent number: 7639339
    Abstract: In a liquid crystal display device including an array substrate which is provided with contact holes and a counter substrate which is provided with integral spacers and aligned with the array substrate, an overall region including every pixel region is divided into a plurality of subregions, each of which includes two or more said spacers and is composed of at least one said pixel region. The spacers are so arranged that when one or some of the spacers are positioned to get into the corresponding contact holes, the rest of the spacers are positioned off the corresponding contact holes.

  • Patent number: 7639619
    Abstract: A system and method configures quality-of-service (QoS) in a segment of a network that has multiple segments with an intermediate device between the segments. The network may be a home network for the transmission of audio-video traffic streams between a media server or source, like a personal computer (PC), and a media renderer or sink, like a digital TV, with the intermediate device being a router, bridge or hub connected to its own network segment and located between the source and sink. One of the network devices contains a QoS parameter holder (QPH). After QoS has been configured in the source and sink and the traffic stream established, the intermediate device detects the traffic stream and determines that it needs to set up QoS. The intermediate device queries the QPH with a traffic stream identifier. The QPH finds the traffic descriptor that matches the traffic stream identifier and returns to the intermediate device the traffic descriptor that includes the QoS parameters.

  • Patent number: 7639472
    Abstract: An ion generating element (10) has at least one first discharger (12) for generating positive ions and at least one second discharger (13) for generating negative ions, both fitted or printed on a single dielectric member (11). The first and second dischargers (12) and (13) are each composed of a pair of a first or second discharging electrode (12a) or (13a), respectively, formed on the surface of the dielectric member (11) and a first or second induction electrode (12b) or (13b), respectively, buried in the dielectric member (11), and are arranged both on the same flat surface of the dielectric member (11) but separately from and independently of each other. This construction helps to alleviate the neutralization among the generated ions themselves, thus to effectively release both positive and negative ions, and thereby to enhance the ion generation efficiency.
