Patent number: 9921564Abstract: A PLC compares previously acquired device data with currently acquired device data when collecting device data on a control target device over three or more times within one polling time, and stores changed device data as changed data when they are different from each other. When transmitting the changed data to a PC in each polling, the PLC compares the changed data with collected device data. When the total amount of changed data is equal to or larger than the total amount of collected device data, the PLC restores collected device data by using the changed data and transmits the restored device data to the PC, and, when the total amount of changed data is smaller than the total amount of collected device data, the PLC transmits the changed data to the PC.Type: GrantFiled: March 17, 2014Date of Patent: March 20, 2018Assignee: Mitsubishi Electric CorporationInventor: Takashi Yoshikawa

Patent number: 9671740Abstract: A print control apparatus includes a generating unit that generates clear-toner plane data based on gloss-control plane data, which contains a gloss control value for specifying a type of a surface effect being a visual or a tactile effect applied to the recording medium and for specifying a region to which the surface effect is applied in the recording medium, and clear plane data, which contains a density value for specifying a transparent image other than the surface effect; and an outputting unit that outputs the clear-toner plane data. When a region where the gloss control value is specified in the gloss-control plane data and a region where the density value is specified in the clear plane data overlap each other, the generating unit sets a value of the clear-toner plane data to the gloss control value or the density value, based on a predetermined condition.Type: GrantFiled: May 3, 2016Date of Patent: June 6, 2017Assignee: RICOH COMPANY, LTD.Inventors: Takashi Yoshikawa, Hiroaki Suzuki, Hiroo Kitagawa
