Patent number: 11974389Abstract: A low dielectric substrate for high-speed millimeter-wave communication includes a quartz glass cloth with a dielectric loss tangent of 0.0001 to 0.0015 and a dielectric constant of 3.0 to 3.8 at 10 GHz, and an organic resin with a dielectric loss tangent within 80% to 150% of the dielectric loss tangent of the quartz glass cloth at 10 GHz and a dielectric constant within 50% to 110% of the dielectric constant of the quartz glass cloth at 10 GHz. This provides a low dielectric substrate for high-speed millimeter-wave communication where the low dielectric substrate makes it possible to send signals that are stable and have excellent quality with no difference in propagation time between wirings even if the substrate has an uneven resin distribution and the quartz glass cloth above and below the wirings, and the difference in dielectric loss tangent between members has been reduced to lower transmission loss.Type: GrantFiled: March 8, 2023Date of Patent: April 30, 2024Assignee: SHIN-ETSU CHEMICAL CO., LTD.Inventors: Toshio Shiobara, Yusuke Taguchi, Ryunosuke Nomura

Patent number: 8743175Abstract: A photographing apparatus has two binocular stereoscopic modes. In two-take photography mode, a 3D image file is generated from left and right monocular images acquired by performing monocular photographing twice, and the 3D image file thus generated is recorded. In one-take photography mode, a 3D image file is generated from left and right monocular images acquired by performing binocular photographing once, and the 3D image file thus generated is recorded. When the 3D image file is recorded, a homogeneity tag is recorded in 3D metadata, as tag information of the header data portion of the 3D image file. The homogeneity tag is information about the homogeneity of the two monocular images and describes whether the two monocular images have been acquired in the one-take photography mode in which monocular images highly homogeneous are provided, or in the two-take photography mode in which monocular images not so homogeneous are provided.Type: GrantFiled: January 17, 2008Date of Patent: June 3, 2014Assignees: Olympus Imaging Corp., Sanyo Electric Co., Ltd., Sharp Kabushiki Kaisha, Sony CorporationInventors: Hideaki Yoshida, Ken Mashitani, Toshio Nomura, Tadashi Uchiumi, Hidehiko Sekizawa

Patent number: 8599919Abstract: An image quality/rate control portion 106 confirms whether a predictive code amount Ci is a target code amount Rt or less. When the predictive code amount Ci is the target code amount Rt or less, the predictive code amount Ci is output to a base layer coding portion 101. Then, a switch 108 is turned off. When the predictive code amount Ci exceeds the target code amount Rt, the target code amount Rt is output to the base layer coding portion 101. Then, the switch 108 is turned on and (predictive code amount Ci?target code amount Rt) is output to an enhancement layer coding portion 103. A buffer 104 stores coded data of the base layer coding portion 101 and the enhancement layer coding portion 103. In this manner, while performing fixed bit rate coding using a single transmission path, image quality of a moving image is made constant so as to prevent deterioration of image quality.Type: GrantFiled: January 26, 2009Date of Patent: December 3, 2013Assignee: Sharp Kabushiki KaishaInventors: Toshiyuki Yoshida, Tomoko Aono, Norio Itoh, Toshio Nomura, Tomohiro Ikai, Takeshi Tsukuba
