  • Publication number: 20180212478
    Abstract: A method for manufacturing a laminated iron core includes providing a plurality of annular iron core piece rows, each of which is configured by annularly arranging a plurality of divided iron core pieces including yokes and teeth, and the yokes of the annularly-adjacent divided iron core pieces in the annular iron core piece row are mutually different in shape. In the method, the annular iron core piece rows are laminated by changing a rotational angle of the newly laminated annular iron core piece row relatively to the lastly laminated annular iron core piece row laminated so that the divided iron core piece with a shape different from that of the divided iron core piece is laminated on the lastly laminated divided iron core piece.

  • Publication number: 20180041358
    Abstract: In a communication device, when an enabling signal is at a high level and a transmit data is at a high level, that is, in a recessive period, both transistors turn off and both transistors turn off. Thus, potentials of signal lines are determined by power supply from a second transmitting part to a communications network. When an error frame arises in this state, that is, transistors in the other ECU turn on, excessive currents flow the signal lines. When current monitoring circuits detect error currents, an error signal is changed to a high level.

  • Publication number: 20180041361
    Abstract: A transmission circuit includes a first transmitter and a second transmitter. The first transmitter turns OFF first transistors when a transmission data is in a high level, and turns ON the first transistors when the transmission data is in a low level. When a permission signal is in the high level, the second transmitter turns ON the second transistors when the transmission data is in the high level, and turns OFF the second transistors when the transmission data is in the low level. Diodes are set to suppress an amplitude of a differential signal in an ON time of the second transistors more than an amplitude of a differential signal in an ON time of the first transistors, to suppress ringing and radiation noise.

  • Patent number: 9760815
    Abstract: With this invention, color shifting correction is performed first based on shifting amount information indicating a shifting amount with respect to the scanning direction on an image carrier of each image forming unit, and halftone processing is then performed, thus suppressing generation of moiré due to the color shifting correction, and forming a high-quality image. To this end, an image forming engine has color shifting amount storage units C, M, Y, and K (black) which store actual shifting amounts with respect to ideal scan directions on image carriers C, M, Y, and K in image forming units C, M, Y, and K. Color shifting correction amount arithmetic units C, M, Y, and K calculate color shifting correction amounts for respective color components on the basis of the stored color shifting amounts.

    Abstract: Status information concerning a particular terminal can be provided through a simple arrangement while utilizing a general-purpose network. A terminal which generates status information has a status sensing unit for sensing the status of the terminal or of an input/output unit. Information representing the status sensed is converted to text-format data and is transferred to a server on a network such as the Internet at predetermined time intervals by a unit for generating transmitted data. The data is stored as a file. An information display terminal uses a browser to read the data out of the server and display the data.
