  • Publication number: 20050143855
    Abstract: When creating other tool path from two tool paths for cutting a work accurately and efficiently, the data on the first tool path is composed of a position vector and a direction vector of a tool for use when the work is cut while moving the tool. The data on the second tool path is composed of a position vector and a direction vector of the tool for use when the work, which has been cut according to the first tool path, is further cut. A computer uses the first tool path data and second tool path data to calculate a position vector and a direction vector of a medium tool path that is between the first tool path and second tool path.

  • Publication number: 20050046881
    Abstract: An image processing apparatus includes an image reading apparatus reading an image of a manuscript and a printer engine performing image formation on a medium based on image data of the read image of the manuscript, and performs a copying function in accordance with various image kind modes. An image accumulation part accumulates, in a storage device, image data that are input in a first image kind mode. A data format conversion part converts the image data accumulated in the storage device by the image accumulation part to image data of a second image kind mode in accordance with a processing condition. An image data delivering part transmits, to an external instrument connected to the image processing apparatus via a network, the image data of the second image kind mode subjected to conversion by the data format conversion part.

  • Publication number: 20040263890
    Abstract: An image formation apparatus, a computer-executable program, and a computer-readable storage medium are disclosed. Image data provided from an external source produce an image having the same quality as an image produced from image data inside the image information apparatus. This is realized by a data format conversion unit converting the image data in a first data format provided by the external source to a second data format that is used by the image formation apparatus. In addition, a halftone process is performed. The image data are received from the external source, such as a PC, through a network interface control unit, and held by a storage unit.

  • Publication number: 20040114172
    Abstract: An image reader scans a document to thereby acquire image data. This image data is in a first format and is stored in a memory. When an external device requests for the image data, a format converter, converts the image data in the first format into an image data in a second format that is acceptable to the external device. The external device forms an image on a recording medium using the image data in the second format.

  • Patent number: 6734382
    Abstract: A method for forming an indicator portion on a push switch such as a pushbutton switch or a membrane switch, the indicator portion being excellent in terms of design property and image quality and allowing fine picture patterns, designs, etc. that are difficult to be reproduced with conventional printing systems to be represented with high resolution, and to provide a push switch having the indicator portion. In order to form the indicator portion, in which a color design image such as a letter, a pattern, design etc is indicated, on the push switch, there are performed the following steps of: forming a colorant layer by printing a color design image on a base sheet by a printer; transferring the colorant layer to a transfer resin through an adhesive, the transfer resin constituting a surface of the push switch; and forming the indicator layer on the transfer resin by peeling off the base sheet and using the colorant layer as the indicator layer.

  • Publication number: 20030204951
    Abstract: A dummy piezoelectric element is disposed at least at one of the ends of an array of piezoelectric vibration elements. A region not including internal electrodes is provided in the vicinity of the outer side surface of the dummy piezoelectric vibration element to be formed. When the outer side surface of the dummy piezoelectric element is cut, a shift of a cutting line from a correct cutting line, which is due to high hardness of the internal electrodes, is minimized.
