  • Publication number: 20050068331
    Abstract: An image processing system and method includes selecting a color desired by a user, extracting a partial image corresponding to the color desired by the user and selected from a bit-map image, converting the partial image into vector data, storing the vector data in a memory, and setting the converted vector data as vector data to be processed as desired by the user. The image processing system and method further includes calculating a palette color from the bit-map image, extracting a partial image corresponding to the palette color, converting the partial image into vector data per color object, storing the vector data in a memory, and setting, as vector data to be processed as desired by the user, vector data per object that is selected from the vector data stored in the memory based on the color selected from the calculated palette colors.

  • Patent number: 6636327
    Abstract: An image processing apparatus is controlled in accordance with the status of an interface and the contents of data. Specifically, so long as the number J of jobs, which are executed by the copier system at the same time, and the number N of channels, which are required by a target job during one cycle, are obtained, dynamic paper feeding timing Wd can be acquired from ideal paper feeding timing Ws, while taking delay time X into account. The preceding paper feeding is performed using paper feeding timing Wd. Further, based on predicted data, a check is performed to determine whether image transmission will be successful without a buffer memory being used. When it is determined that the buffer memory is not required for the image transmission, image data are received without the buffer memory being obtained. When it is determined that the buffer memory is required for the image transmission, an adequate buffer memory is acquired for the reception of image data.

  • Patent number: 6335223
    Abstract: A lead frame used for a resin-sealed semiconductor device includes a die-mount portion on which a semiconductor chip rests; and a plurality of leads arranged along a common portion of the lead frame. The plurality of leads include at least one adjusting lead, and the adjusting lead has a length that is less than the others of the plurality of leads such that a tip of the adjusting lead is sufficiently proximate to an outer peripheral surface of a resin-seal body to prevent resin flash during a formation of the semiconductor device and to allow the adjusting lead to be removed after the resin-seal body is formed over a portion of the lead frame.

  • Patent number: 6041265
    Abstract: An operational control device of an image processing apparatus displays set color-balance settings on the corresponding keys with the corresponding figures and bar graphs. It also displays the title of a color-balance setting, as required. This facilitates the confirmation of set processing conditions in storing plural processing conditions for image processing, and also facilitates the selection of stored processing conditions to read. When a magnification is specified in the XY zoom mode, the key indicating that the mode has been specified is displayed. Pressing this key displays the XY zoom setting screen again. This facilitates the confirmation and change of set processing conditions.

  • Patent number: 5187123
    Abstract: This invention relates to a die bonding method used for adhering the die of a semiconductor device to a die pad of lead frame. Adhesive paste is applied in spots on the surface of the die pad by means of plural nozzles arranged radially, pressing a die thereon to spread the adhesive paste widely, and adhere the die to the die pad by hardening the adhesive paste. When the plural nozzles are arranged radially in this manner, the adhesive paste applied in spots on the die pad surface is also radial. Accordingly, when the die pad is pressed on, the adhesive paste spreads widely along the back surface of the die while forcing out air, thereby preventing voids from staying inside the adhesive paste. As a result, the die adhesion strength is increased, and the thermal and electrical conductivity are improved.

  • Patent number: 5184664
    Abstract: A mold for lead casting comprising a porous metal material which does not form an alloy with molten lead and which has a thermal conductivity of from 3-15 kcal/(m.multidot.hr.multidot..degree.C.) and having a percentage of pores having a radius larger than or equal to 40 microns being 7% or less of the total pore volume. The porous metal material has a permeability of at least 0.2 ml/sec.multidot.cm.sup.2 at a material thickness of 10 mm and ambient pressure of 0.02 kg/cm.sup.2. A casting mold enabling casting of a lead grid without using a lubricant due to the lubricity of the mold material itself is realized.
