Patent number: 8416227Abstract: A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixel circuits 1 and a plurality of optical sensors 2 which are arranged two-dimensionally. Infrared light transmitting filters 3 that allow infrared light to pass therethrough and cut off visible light are provided in respective paths of light entering the optical sensors 2. A backlight 15 including white LEDs 4 and infrared LEDs 5 is provided on a back surface of the liquid crystal panel 11. With this, reflected light of backlight light including infrared light is detected by the optical sensors 2 without receiving the influence of visible light, and thus a touch position is detected with high accuracy, irrespective of display data.Type: GrantFiled: February 16, 2009Date of Patent: April 9, 2013Assignee: Sharp Kabushiki KaishaInventors: Akizumi Fujioka, Toshimitsu Gotoh, Akinori Kubota, Masaki Uehata

Patent number: 8411117Abstract: The present invention relates to a display device that has a plurality of optical sensors provided in a display panel and that can be operated by touching a screen with a finger or pen. A liquid crystal panel with built-in sensors (11) includes a plurality of pixel circuits (1) and a plurality of optical sensors (2) which are arranged two-dimensionally. An MPU (18) selects either a mode that detects a shadow image of an object or a mode that detects a reflection image of the object, based on an illumination of outside light. One frame time is divided into a display period and a sensing period. A backlight (14) is controlled to be turned on during the display period in the shadow image mode and during the sensing period in the reflection image mode, and to be turned off during the sensing period in the shadow image mode and during the display period in the reflection image mode.Type: GrantFiled: December 17, 2008Date of Patent: April 2, 2013Assignee: Sharp Kabushiki KaishaInventors: Akizumi Fujioka, Akinori Kubota

Publication number: 20110012879Abstract: A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixels 1 and a plurality of optical sensors 2 which are arranged in a row direction and a column direction. The optical sensors 2 are provided to be associated with pixels 1 in every other row (e.g., to be associated with pixels 1 in even rows). A panel drive circuit 16 performs one-line inversion drive and reads signals based on the amounts of received light, from the optical sensors 2. Since the outputs from the optical sensors 2 change in the same direction due to the influence of display data, stripe noise resulting from the switching of the polarities of voltages written into pixel circuits 3 is prevented from occurring in an image generated based on the outputs from the optical sensors 2.Type: ApplicationFiled: March 12, 2009Publication date: January 20, 2011Inventors: Masaki Uehata, Akinori Kubota, Akizumi Fujioka, Toshimitsu Gotoh

Publication number: 20080130899Abstract: When a decryption-key request is transmitted from a client computer to a management server via a network apparatus, the network apparatus instead of the client computer adds location information to the decryption-key request. When the decryption-key request reaches the management server, location information stored therein is compared with location information associated with the decryption-key request. When the two pieces of the location information are the same, a decryption key is transmitted to the client computer. Thus, only when the management server receives the decryption-key request via the network apparatus which adds the specific location information to the decryption-key request, the management server transmits the decryption key to the client computer. This allows the encrypted data to be accessed within a specific area.Type: ApplicationFiled: November 2, 2007Publication date: June 5, 2008Applicant: Fujitsu LimitedInventors: Eiji Iwamoto, Akio Yonehara, Takashi Ikeda, Akinori Kubota

Publication number: 20070274234Abstract: The present invention provides a method in which the physical connection information and the logical network configuration information are kinked to the status of spanning tree, and the status of spanning tree is displayed with the physical connection and the logical network configurations. The method can provide the better recognition about not only intended the physical and logical configurations but the status of spanning tree to a network administrator. Therefore, the network administrator can integrally recognize the status of the network and the failure in the network will be analyzed easily to recover the network to normal state in shorter time.Type: ApplicationFiled: May 25, 2007Publication date: November 29, 2007Applicant: Fujitsu LimitedInventor: Akinori KUBOTA

Patent number: 5378425Abstract: A method for vulcanizing a tire wherein firstly heating medium is blown toward a tire internal surface from a supply opening arranged at a position above an equator of the tire in a mold and secondary pressurizing medium is blown toward the tire internal surface from the supply opening, and an apparatus used therefor. By virtue of the method and the apparatus, in vulcanization, abnormal cooling at a lower bead of a tire is prevented and consequently a large temperature difference inside the tire is prevented, so that uniform vulcanization can be carried out to provide products having high quality. Further, prevention of the temperature difference makes it possible to shorten a time period required for vulcanization, to improve productivity, and to reduce energy loss.Type: GrantFiled: October 16, 1992Date of Patent: January 3, 1995Assignee: Sumitomo Rubber Industries, Ltd.Inventors: Akinori Kubota, Yoshiya Kubota, Shoji Okatmoto, Masaaki Ijiri, Koji Soeda
