  • Patent number: 7972949
    Abstract: An electronic component or display device of the present invention can be provided by using a following pattern formation method. On a substrate treated with a first etching with a first resist pattern as a first mask, a second resist pattern is transfer-printed on the first resist patterns so as to partially overlap with the first resist pattern and partially extended from the first resist pattern. And then a second etching is performed by using the first resist pattern and the second resist pattern as a second mask. The first resist pattern and the second resist pattern are used for forming wirings and/or terminals, and the extended portion of the second resist pattern is used to make the wirings to have a cross section of a stair-like edge shape.

  • Patent number: 7676701
    Abstract: A computer readable medium stores a program causing a computer to execute a process for error recovery. The process includes: when an error is detected during transfer of dummy data for maintaining a link, executing device reset to recover from the error, and monitoring whether or not another error occurs during an error monitoring period starting from the device reset; when the other error occurs during the error monitoring period, executing the device reset to recover from the other error, monitoring whether or not still another error occurs during the error monitoring period starting from the device reset; counting number of the successive error monitoring periods in each of which the error occurs; and judging an error occurrence state based on a result of the counting.

  • Publication number: 20100033531
    Abstract: When recording heads are away from caps, a black ink recording head is first set into a capping state and a color ink recording head is subsequently set into a capping state from this state. When the recording heads are adhered to the caps, the capping state of the color ink recording head is first cancelled and the capping state of the black ink recording head is subsequently cancelled from this state.

  • Publication number: 20090309919
    Abstract: An inkjet recording apparatus includes an encoder, a storage section, a difference calculating section, a threshold value determining section, a correction amount calculating section, and a controlling section. The storage section stores a capping target position and threshold value. The difference calculating section calculates a difference between a stopping position where a carriage is stopped for capping the recording head and a carriage position after passage of a predetermined time from when the carriage is stopped at the stopping position. The stopping position and carriage position are detected by the encoder. The threshold value determining section compares the threshold value and difference with each other. When the difference is greater than the threshold value, the correction amount calculating section calculates a correction amount of the capping target position. The controlling section moves the carriage to the capping target position corrected on the basis of the correction amount.

  • Publication number: 20090309916
    Abstract: A cleaning mechanism has a slider moving together with a carriage and a suction cap provided on the slider to cap one of print heads mounted on the carriage to perform suction therefrom. A first contact portion and a second contact portion are provided in each of the carriage and the slider, and a third contact portion and a fourth contact portion are provided in the slider. In the case that the suction cap performs suction from a black head, when the carriage moves toward the cleaning mechanism side, the first contact portion and the third contact portion come into contact with each other to position the carriage and the slider in such a manner that the suction cap faces the black head.
