Publication number: 20260065624Abstract: The display device includes an acquisition processing unit, a rectangle candidate detection processing unit, and a one-character extraction processing unit. The acquisition processing unit acquires image data including characters. The rectangle candidate detection processing unit detects a rectangle candidate of a character from the image data, and calculates a reliability of the detected rectangle candidate. The one-character extraction processing unit corrects, in a case where a first rectangle candidate and a second rectangle candidate detected by the detection processing unit at least partially overlap each other, a reliability of a rectangle candidate to be corrected out of the first rectangle candidate and the second rectangle candidate by using a calculation method for a degree of overlap selected according to a relationship between a type of a first detection target corresponding to the first rectangle candidate and a type of a second detection target corresponding to the second rectangle candidate.Type: ApplicationFiled: August 14, 2025Publication date: March 5, 2026Inventor: Daisuke IGARASHI

Patent number: 9581992Abstract: In a conventional CAM apparatus, cutting regions and a tool axis angle by which the cutting time is minimized cannot be automatically set for a finish shape having a free formed surface shape. Accordingly, the CAM apparatus generates quadrangle-shaped patterns of cutting regions using coordinate data of a finish shape and an initial shape. Triangle-shaped cutting regions are generated for concave-convex faces of the finish shape. For cutting regions generated by subtraction by boolean operation with a subtract shape calculated by subtraction by boolean operation between the initial shape and the finish shape, the tool axis angle is set so that the tool does not interfere and the face is maximized. For other regions, the tool axis is set so as to satisfy a remainder standard and to minimize a tool path length.Type: GrantFiled: December 18, 2013Date of Patent: February 28, 2017Assignee: Mitsubishi Hitachi Power Systems, Ltd.Inventors: Takahiro Nakano, Hiroshi Arai, Reiko Inoue, Daisuke Tsutsumi, Daisuke Igarashi, Masakazu Okubo

Patent number: 8542835Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover.Type: GrantFiled: February 5, 2009Date of Patent: September 24, 2013Assignee: NTT DoCoMo, Inc.Inventors: Motoshi Tamura, Mutsumaru Miki, Akiko Okamoto, Kenya Kusunose, Akihiro Uchikoshi, Daisuke Igarashi, Katsuhiko Yamagata, Takaaki Sato, Junichiro Hagiwara, Yasuyuki Watanabe, Takuya Hamajima, Masafumi Hata, Nobutaka Ishikawa, Yoshiyuki Yasuda, Kazufumi Yunoki, Nobuhide Uchiyama
