  • Patent number: 7369707
    Abstract: The intra-picture prediction coding apparatus 150a is comprised of: an intra-picture prediction mode candidate determination unit 156a that determines intra-picture prediction mode candidates by switching among intra-picture prediction mode candidate determination methods based on an amount of resources 172; an intra-picture prediction execution unit 151 that sequentially performs intra-picture prediction on a current block using each of intra-picture prediction modes in the intra-picture prediction mode candidates and generates an intra-picture predictive image 164; a prediction difference calculation unit 152 that generates a prediction difference image 165 based on the intra-picture prediction image 164 and the image presented by the current block; a coding efficiency evaluation unit 153 that calculates an evaluation value 166 based on the prediction difference image 165; an intra-picture prediction mode determination unit 154 that determines the intra-picture prediction mode whose evaluation value 166 is

  • Publication number: 20050096836
    Abstract: An operation management system is provided, which includes a database (105) that accumulates operation information, including a fuel consumption amount, that is gathered from a running vehicle (A1 to B2) through a network (20); and a management device (103, 104) that sends the gathered operation information and the operation information accumulated in the database (105) to a client computer (A10, B10) through the network (20). The management device (103, 104) receives an instruction for the vehicle (A1 to B2) from the client computer (A10 and B10), and sends the received instruction to the vehicle (A1 to B2).

  • Publication number: 20050047673
    Abstract: A filter device includes a vertical NR process portion (14), a vertical resolution conversion portion (12) and a vertical NR process decision portion (20). The vertical NR process portion (14) receives a horizontal NR processed signal (26) and produces an NR processed signal (27). The vertical resolution conversion portion (12) includes a plurality of resolution conversion filters and uses the NR processed signal (27) to perform a vertical resolution conversion. The vertical NR process decision portion (20) decides whether or not the vertical NR process portion (14) should perform the vertical NR process on the horizontal NR processed signal (26) in accordance with a resolution conversion filter selection signal (32) for selecting one of plurality of resolution conversion filters for the vertical resolution conversion portion (12).

  • Patent number: 6548713
    Abstract: The process of this invention efficiently produces a compound having an alkyl group or alkenyl group bonded at the alpha position of an electron attractive group, or a derivative thereof, by catalytic radical addition reaction. The process reacts a compound containing an electron attractive group of Formula (1) as defined in the specification with a compound containing an unsaturated carbon-carbon bond of Formula (2) or (7) as defined in the specification to produce a compound of Formula (3) or (8) as defined in the specification. The invention is characterized by carrying out the reaction in the presence of oxygen and a catalytic compound of a Group 7, 8, or 9 element of the Periodic Table of Elements.

  • Patent number: 6468487
    Abstract: In the presence of an imide compound (e.g., N-hydroxyphthalimide) shown by the following formula (1): wherein R1 and R2 represent a hydrogen atom, a halogen atom, an alkyl group, an aryl group and a cycloalkyl group, and R1 and R2 may bond together to form a double bond, or an aromatic or non-aromatic ring, and Y is an O or OH, and n denotes 1 to 3; a substrate is allowed to contact with at least one reactant selected from (i) a nitrogen oxide and (ii) a mixture of carbon monoxide and oxygen to be introduced with at least one functional group selected from a nitro group and a carboxyl group. The nitrogen oxide includes, for example, a compound represented by the formula NxOy (e.g., N2O3, NO2). The substrate includes, for example, a compound having a methine carbon atom (e.g., adamantane), a compound having a methyl group or a methylene group at an adjacent moiety of an aromatic ring.

  • Patent number: 5956657
    Abstract: The method provides nitro compounds at a high conversion and selectivity by nitrating substrates under comparatively mild conditions in the absence of catalysts. Organic substrates are nitrated using no catalysts or ozone, but using (1) at least one nitrogen compound selected from N.sub.2 O or NO and oxygen. It is advantageous for the nitration reaction to employ a nitrogen compound obtained by a reaction of the nitrogen compound with oxygen, particularly a nitrogen oxide comprising N.sub.2 O.sub.3 as a main component. Additionally, organic substrates are nitrated using (2) NO.sub.2. The substrates include a compound having a methine-carbon atom, and a compound having a methyl group or methylene group in an adjacent position to an aromatic ring.
