  • Publication number: 20110247929
    Abstract: A diamond electrode having an oxidation resistant diamond film which will not separate from the electrode during electrolysis with highly oxidizing materials. The thickness of the diamond film is 20 pm or more and the diamond film should preferably cover opposite side surfaces of a substrate in such a manner as to also cover end surfaces 2a of the substrate. The surfaces of the substrate are covered with a plurality of diamond layers to form the film using repeated steps of forming separate diamond layers with each diamond layer having a thickness of 10 to 30 pm on one of the surfaces of the substrate and then forming a diamond layer having a thickness of 10 to 30 pm on the other surface of the substrate. Thus, it is possible to form a nonporous surface of diamond layer and prevent deterioration of an electrode caused by the separation of a diamond film.

  • Patent number: 7968552
    Abstract: A compound which can be used as a pharmaceutical, particularly a insulin secretion promoter or a agent for preventing/treating disease in which GPR40 is concerned such as diabetes or the like, is provided. It was found that an oxadiazolidinedione compound which is characterized by the possession of a benzyl or the like substituent binding to the cyclic group via a linker at the 2-position of the oxadiazolidinedione ring, or a pharmaceutically acceptable salt thereof, has excellent GPR40 agonist action. In addition, since the oxadiazolidinedione compound of the present invention showed excellent insulin secretion promoting action and blood glucose level-lowering action, it is useful as an insulin secretion promoter or an agent for preventing/treating diabetes.

  • Patent number: 7899342
    Abstract: When forming an image, if there are not enough sheets remaining in a paper feed cassette to satisfy the image forming request, the image forming operation is not executed, and along with prompting the user to refill the paper, the paper feed cassette is pushed out towards an uninstalled state. The apparatus waits for a paper refill, and begins the image forming operation after that paper refill.

  • Publication number: 20100195724
    Abstract: When a periodic pattern is not included in image data 210, a prediction error encoding unit 204 outputs the variable-length code of a prediction error quantization value 214 generated by prediction encoding as compressed data 215. When the periodic pattern is included in the image data 210, a periodic pattern encoding unit 208 outputs only information about the periodic pattern as the compressed data 215, while the output of the prediction error encoding unit is stopped. On the decompression side, while the copy instruction of a pixel value before one cycle from the compressed data is not detected, the decompression operation in a normal prediction encoding system is executed. When the instruction is detected, the pixel value one cycle before, internally stored is copied and outputted.

  • Patent number: 7761046
    Abstract: Mechanism unit(s) functioning as automatic-feed cassette(s) and mechanism unit(s) functioning as manual-feed tray(s) together form a single integral module, constituting a hybrid paper supply module. A plurality of hybrid paper supply modules are stacked together to constitute a paper supply mechanism. Manual-feed tray(s) with which manual-feed mechanism unit(s) of respective hybrid paper supply module(s) is or are provided is or are maintained in stored state(s) as a result of electromagnetic attraction produced by electromagnet(s). In correspondence to image forming condition(s), electromagnetic attraction at one electromagnet is terminated, causing manual-feed tray(s) to assume deployed state(s). Furthermore, primary path(s) passing vertically through module interior(s) is or are formed so as to permit transport of recording paper toward printing unit(s) of hybrid device(s) regardless of from which hybrid paper supply module(s) it is that recording paper is taken up.

  • Publication number: 20100074545
    Abstract: In the present invention, a first pixel data group of several pixels existing in block into which an image is divided is divided, thereby generating several second pixel data groups. In the second pixel data group, an orthogonal transformation is performed in several layers using only the predetermined number of coefficients from the lowest frequency side from among the coefficients obtained by the orthogonal transformation. The predetermined number of coefficients from the lowest frequency side from among the coefficients obtained by the orthogonal transformation in the highest layer, and the coefficients that are obtained in a layer other than the highest layer not used for the orthogonal transformation are encoded, thereby generation the compressed data. Accordingly, encoding is performed while separating lower frequency components from higher frequency components.

  • Publication number: 20090052530
    Abstract: A quantizer quantizes a “prediction error” as a difference value between a pixel X to be compressed and a prediction value X?. A variable-length encoder inputs a quantization number obtained from a quantization table of the quantizer, and outputs a variable-length code (compressed code). A prediction value candidate calculation module calculates candidates 1 through k for a prediction value on the basis of peripheral pixels A, C, and B, and transmits them to a multiplexer (MPX). A prediction value determination module determines a prediction value among the candidates 1 through k for a prediction value on the basis of an intermediate value correspondence table and an intermediate value—image format correspondence table depending on an image format, and transmits a control signal to the multiplexer (MPX). The multiplexer (MPX) outputs one of the candidates 1 through k for a prediction value as a prediction value X?.
