Patent number: 11934901Abstract: A tag indicating an attribute of the tag by an electromagnetic wave reflection characteristic, the tag including a substrate (11), and a conductor pattern layer (12) formed on the substrate (11) and having first and second slots (13a) and (13b) disposed adjacent to each other, in which the first slot (13a) constitutes a first resonance element (13Qa) having a resonance frequency at a first frequency, the second slot (13b) constitutes a second resonance element (13Qb) having a resonance frequency at a second frequency higher than the first frequency, and when irradiation with the electromagnetic waves is performed, a Q value of a resonance peak appearing at the first frequency is higher than a Q value of a resonance peak appearing at the first frequency when the first slot (13a) alone constitutes a resonance structure of the tag.Type: GrantFiled: August 21, 2020Date of Patent: March 19, 2024Assignee: Konica Minolta, Inc.Inventors: Takumi Ishiwata, Nobuaki Takahashi, Kenji Arai, Takeshi Hakii

Patent number: 7825762Abstract: A case 12 of a transformer 10 formed in such a manner that a transformer body 13 is accommodated in the case 12 having a rectangular-parallelepiped shape and a resin 14 is filled therein and solidified is configured such that the case 12 has one open face, and side faces 22a, 22b, 22c and 22d located at borders of the opening is partially removed, and tape is attached to cover the removed portions 23a, 23b, 23c and 23d. With this configuration, since the tape which is sufficiently thinner than the case forms side faces at the removed portions, gap between the transformer body and the case hard to be reduced. Accordingly, the resin is allowed to easily enter therein and air bubbles can be completely removed.Type: GrantFiled: December 10, 2004Date of Patent: November 2, 2010Assignee: Tamura CorporationInventor: Nobuaki Arai

Publication number: 20060085755Abstract: A learning supporting system includes: a contents transmitting unit for collecting contents according to a request from a client from a database in which contents information have been stored on the basis of the request and sending them to the client; and an additional information transmitting unit for collecting tag information or marker information on the basis of the collected contents and user information included in the request from a database in which the tag information and the marker information have been stored and transmitting the collected information to the client. The client has: an additional information selecting unit for selecting the tag information or the marker information designated by the user in the transmitted tag information or marker information; and a display unit for displaying the transmitted contents and the tag information or marker information selected by the additional information selecting unit.Type: ApplicationFiled: May 9, 2003Publication date: April 20, 2006Inventor: Nobuaki Arai

Patent number: 6926610Abstract: The objective is to prevent erroneous operation of an optical sensor while removing restrictions on the degree of freedom of design. In a handgun-shaped controller comprising a lens for focusing light that is incident on a muzzle and an optical sensor 18 for detecting the thus-focused light, a light-proof case 50 is provided to cover the lens and optical sensor in such a manner that external light other that from a muzzle is not incident thereon. The light-proof case covers the entire surface of the optical sensor and the portion of the board on which the optical sensor is mounted. Cut-out portions 54A and 54B for through-holes for signal terminals 19 are provided in a connection portion between parts 50A and 50B that form the light-proof case. A protuberant portion is provided on the connection portion of one part 50A and a fit portion thereof is provided in the connection of another part 50B.Type: GrantFiled: June 27, 2001Date of Patent: August 9, 2005Assignees: Namco Ltd., Tamura CorporationInventors: Masatoshi Kobayashi, Nobutaka Kobayashi, Nobuaki Arai

Patent number: 6677935Abstract: An objective is to provide a position pointing device, a program and a method for detecting the position pointing device which relates to a device pointing a position on a display screen and which can discriminate a scan mode of a display device and obtain information of pointed position by performing a processing corresponding to the discriminated scan mode. A photosensor (18) provided in the position pointing device detects a scanning beam from a display device (140) and generates a light detection signal. A scan mode discriminating section (30) judges that a scan mode in the display device is not a standard scan mode type, but a multi-density scan type if a frequency component of the light detection signal includes a frequency component of a horizontal synchronous signal in a multi-density scan type display device.Type: GrantFiled: November 2, 2001Date of Patent: January 13, 2004Assignees: Namco Ltd., Tamura CorporationInventors: Masatoshi Kobayashi, Yukihiko Yagi, Nobuaki Arai

Patent number: 6032198Abstract: In a method for supporting the design of a plurality of programs distributed on a network and operated through the communication between the programs, each program is defined, a relation between programs is defined, interface information of each program is defined, and the interface defined for each program is converted into an interface definition language (IDL) format to generate an IDL file. The definition of each program and the definition of the relation between programs are performed by providing a graphic display screen to which a program represented by a symbol and a relation between programs represented by an arrow are inputted as definition information by a user. The definition of interface information is performed by inputting information defined by the user in an interactive manner.Type: GrantFiled: March 11, 1998Date of Patent: February 29, 2000Assignee: Hitachi, Ltd.Inventors: Keiji Fujii, Hiroshi Kanegae, Shigetoshi Hayashi, Masanori Yamada, Masaaki Nagao, Nobuaki Arai, Kiyoshi Takahara, Matsuki Yoshino
