Publication number: 20130258242Abstract: A flexible printed circuit board has a length extending in an arrangement direction of light emitting parts and a width extending in a direction orthogonal to the length. Each light emitting part includes electrodes on both end portions thereof respectively along the arrangement direction of the light emitting parts. The flexible printed circuit board includes a wiring pattern. The wiring pattern includes bonding portions where the light emitting part is bonded to the electrodes, and a wiring portion which is arranged between the light emitting parts arranged adjacent to each other. A fixing region portion of the wiring pattern which is positioned in a region where the bonding portion of the flexible printed circuit board is formed and a region displaced from the bonding portion in the width direction is larger than the wiring portion in the width direction.Type: ApplicationFiled: March 27, 2013Publication date: October 3, 2013Applicant: Japan Display East Inc.Inventors: Hiroyuki SHIMOKAWA, Takuya KARUGOME

Patent number: 8304009Abstract: A method is provided for producing a processed tomato product having more tomato aroma inherent to grown tomatoes. Tomato fruits are washed and crushed. Juice is extracted from the crushed material, the extracted juice is deaerated and the deaerated material is heated. The crushed material and the extracted juice from immediately after the crushing until immediately before the deaerating are maintained at temperature of 15-40° C. The dissolved oxygen concentration of the crushed tomatoes and/or the extracted juice from immediately after the crushing until immediately before the deaerating is raised at least temporarily to 6 mg/L or over, and the dissolved oxygen concentration of the deaerated juice immediately before the heating is reduced to 3.5 mg/L or below.Type: GrantFiled: November 10, 2011Date of Patent: November 6, 2012Assignee: Kagome Kabushiki KaishaInventors: Hiroyuki Shimokawa, Takahiro Kawana, Kiro Hayakawa

Publication number: 20120086890Abstract: A mold frame used for a backlight device is thinned to enable a frame of a liquid crystal display device to be narrowed. Gates for injection molding are arranged on an inner side surface of a mold frame. The inner side surface forms recesses in portions including the positions of the gates. Protrusions for preventing optical sheets from dropping out are disposed on an edge of the optical sheets housed within the mold frame in correspondence with the recesses accompanied by the injection molding. The recesses are used for engaging the protrusions, thereby requiring no provision of additional recesses for engaging the protrusions.Type: ApplicationFiled: October 5, 2011Publication date: April 12, 2012Inventors: Hiroyuki SHIMOKAWA, Masamitsu MIYATA

Publication number: 20100027890Abstract: An eye-gaze direction calculation unit calculates the eye-gaze direction in an input facial image of a person by carrying out prescribed operation processing based on iris shape data output from an iris detection unit and face-direction measurement data output from a face-direction measurement unit. The eye-gaze direction of the facial image of the person can be measured on the basis of accurate iris shape information obtained by an iris shape detection unit. The iris and sclera regions can be estimated on the basis of the detected eyelid contour information, thereby making it possible to accurately estimate the shape of the iris.Type: ApplicationFiled: June 10, 2009Publication date: February 4, 2010Inventors: Tomoaki YOSHINAGA, Shigeki Nagaya, Chiharu Sayama, Hideyuki Hidaka, Hiroyuki Shimokawa, Hiroshi Watanabe

Publication number: 20060028154Abstract: The present invention can prolong a lifetime of a liquid crystal display device by suppressing the increase of a leak current attributed to the deflection of a cold cathode fluorescent lamp toward a lower frame side. An insulating member is arranged right below a cold cathode fluorescent lamp and above a lower frame. A reflecting sheet is arranged above the insulating member. The insulating member is formed in a block shape having a rectangular cross section. A fixed or more amount of distance is ensured between the cold cathode fluorescent lamp and the reflecting sheet thus suppressing the increase of the leak current.Type: ApplicationFiled: July 27, 2005Publication date: February 9, 2006Inventors: Hiroyuki Shimokawa, Yoshikazu Nakada, Masashi Baba, Takashi Oota, Shunsuke Morishita

Patent number: 6445471Abstract: In setting pre-emphasis at the transmitting end, each optical signal outputted from a laser diode and an amplified spontaneous emission noise outputted from an ASE output unit are multiplexed at a coupler, and the output power of the amplified spontaneous emission noise, at that time, is changed by an attenuator. In this case, the difference between a reference value, which is the value of an OSNR corresponding to the target lower limit of a Q-value at the receiving end, and the value of a current OSNR is calculated as a margin. Then, the attenuator is controlled so that the margin of an OSNR becomes equal to the average of the margins for all optical signals.Type: GrantFiled: July 21, 1999Date of Patent: September 3, 2002Assignee: Fujitsu LimitedInventors: Hiroyuki Shimokawa, Shinichiro Harasawa
