  • Patent number: 11340736
    Abstract: Provided is an image display method for performing drawing in a display region overlapping at least with a part of an external scene in a state in which the external scene is visible. The image display method images a region including the display region, and extracts an operating object from a captured image in which this region is imaged, as a region of a color of the operating object. In accordance with a size of the region of the color thus extracted, a drawing mode of the operating object is changed, and image display in the display region is controlled in accordance with the changed drawing mode. As the control of the image display, for example, performing drawing, and moving or replicating a drawn image is assumed.

  • Publication number: 20030183553
    Abstract: In order to prevent impairment due to static electricity in a container for an electronic component, generation of static electricity itself has to be inhibited. The peeling static electrification amount of a cover tape should be from −9 to +9 nC when the cover tape has a surface resistivity of at least 1011 &OHgr;, or it should be from −3 to +3 nC when the cover tape has a surface resistivity of less than 1011 &OHgr;. In a carrier tape body, a side of a cover tape which faces an electronic component should have a composition containing a resin on the positive polarity side and a resin on the negative polarity side relative to a side of the electronic component which faces the cover tape in the series of frictional electrification. For the surface of a container to be in contact with an electronic component, a material which is less likely to generate static electricity should be employed.

  • Patent number: 5126782
    Abstract: An image recording apparatus forms the image by using a photo-sensitive sheet accommodated in a cartridge, one side of which has a bar code attached. In this recording apparatus, a remaining amount of the sheet in the cartridge at a given time is calculated by substracting a used amount of the sheet detected by a rotary encoder installed on a motor shaft of a sheet feeding device from a total amount of the sheet detected by reading the bar code through a bar code reading device, and is displayed on a display. And, this recording apparatus corrects the remaining amount of the sheet in the cartridge based on a rewound amount of the sheet detected by the rotary encoder when a single copy mode is selected. Further, the apparatus displays copyable numbers according to the remaining amount of the sheet based on a copy size set.

  • Patent number: 5126781
    Abstract: An image recording apparatus having an exposure unit, a pressure developing unit and a thermal fixing unit. The apparatus employs a separate type image recording mediums including a microcapsule sheet and a separate developer sheet. The thermal fixing unit applies heat to the developer sheet carrying an output image thereon. A heat application means of the thermal fixing unit is positioned spaced away from the imaging surface of the developer sheet for avoding direct contact therewith.
