Patent number: 10921767Abstract: According to an embodiment, an encoder system includes an encoder and an interface. The encoder detects the position and speed of a motor, and generates A-, B- and Z-phase signals. The interface includes an AB waveform recognition circuitry to recognize a waveform of an AB phase, a Z waveform recognition circuitry to recognize a period of an enable state of a Z phase, a starting point storage device to store a value of the AB phase when the Z phase changes and stores an AB-phase change pattern, a starting point recognition circuitry to generate an interrupt signal, and a rotation angle counter to start a new count of the rotation angle of the motor.Type: GrantFiled: August 12, 2019Date of Patent: February 16, 2021Assignees: Kabushiki Kaisha Toshiba, Toshiba Electronic Devices & Storage CorporationInventors: Akihiro Kobayashi, Makoto Kanda, Shigeru Itoh, Hiroshi Nishikawa, Wataru Furuichi, Kiyoshige Taga, Kazuma Takeda

Patent number: 10789144Abstract: According to one embodiment, a supervisory circuit includes a trigger determination circuit and a trigger table. The trigger determination circuit receives signal processing signals outputted from a plurality of signal processing circuits as trigger signals, determines whether processing operations by the signal processing circuits are executed in a predetermined order, and outputs an interrupt signal when detecting a trigger signal out of setting. The trigger table is provided with trigger-specific tables corresponding to the respective signal processing circuits, reads a trigger setting to occur next based on a trigger determined as being correct by the trigger determination circuit, and outputs a table read signal to the trigger determination circuit.Type: GrantFiled: August 31, 2018Date of Patent: September 29, 2020Assignees: Kabushiki Kaisha Toshiba, Toshiba Electronic Devices & Storage CorporationInventors: Akihiro Kobayashi, Makoto Kanda, Shigeru Itoh, Hiroshi Nishikawa, Wataru Furuichi, Kiyoshige Taga, Itsuro Nomura

Patent number: 9656818Abstract: A paper feeding device of an image forming device includes a flotation air blowing unit and a separation air blowing unit. The flotation air blowing unit floats stacked uppermost paper through air blowing. The separation air blowing unit blows an end of other paper floated together with the floated uppermost paper to separate the other paper from the uppermost paper, the end being on the downstream side in the paper feeding direction. The flotation air blowing unit floats an end of the stacked uppermost paper, the end being on the downstream side in the paper feeding direction. The paper feeding device includes a resistance force applying mechanism which applies resistance force that gives a load against movement along the paper feeding direction to an end of stacked upper paper, the end being on the upstream side in the paper feeding direction.Type: GrantFiled: February 26, 2015Date of Patent: May 23, 2017Assignee: KONICA MINOLTA, INC.Inventors: Wataru Furuichi, Kazuyoshi Kimura
