Patent number: 9636912Abstract: Under a condition in which bowed printing occurs, a horizontal shift is suppressed to improve print quality. Following a program stored in a ROM 12, an MPU 10 generates video data for charging print particles according to print contents data stored in a RAM 11. Based on the print contents data, the MPU 10 detects a letter to be printed last, and when the letter to be printed last is printed to end a print operation, generates video data so that based on the video data, a non-print charge voltage driving non-print particles to an extent that they do not fly over a gutter 25 is applied to non-print particles. The number of the non-print particles subjected to the non-print charge voltage is determined by the MPU 10, based on the distance from a print head 2 to a print subject 30, a letter height preset value, etc. A character signal generating circuit 18 generates the non-print charge voltage, based on the video data, and applies the generated the non-print charge voltage to a charging electrode 22.Type: GrantFiled: December 19, 2013Date of Patent: May 2, 2017Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Tsuneaki Takagishi, Nobuhiro Harada, Manabu Kato, Takashi Kawano, Masato Ikegawa

Patent number: 9601256Abstract: Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core.Type: GrantFiled: October 10, 2014Date of Patent: March 21, 2017Assignee: HITACHI INDUSTRIAL EQUIPMENT SYSTEMS CO., LTD.Inventors: Kenji Nakanoue, Kazuyuki Fukui, Hidemasa Yamaguchi, Kouhei Satou, Tatsuhito Azegami, Makoto Shinohara, Toshiaki Takahashi, Tooru Honma, Masanao Kuwabara, Toshiki Shirahata, Yuuji Satou, Manabu Dohi, Ryosuke Mikoshiba, Hiroyuki Endou
