Patent number: 11923123Abstract: A multilayer substrate includes first and second insulating layers stacked in a stacking direction with the second insulating layer located at a first side of the first insulating layer in the stacking direction, a first coil pattern disposed on a first principal surface of the first insulating layer on the first side of the first insulating layer in the stacking direction, and a second coil pattern disposed on a first principal surface of the second insulating layer on the first side of the second insulating layer in the stacking direction. The first and second coil patterns have spiral shapes. When viewed from the layer stacking direction, at least a portion of a first area in which the first coil pattern is disposed and at least a portion of a second area in which the second coil pattern is disposed overlap each other.Type: GrantFiled: October 22, 2018Date of Patent: March 5, 2024Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Kazutaka Muraoka, Kuniaki Yosui, Yuki Ito, Naoki Gouchi

Patent number: 7561225Abstract: Provided is a liquid crystal display device that offers improved heat dissipation and that can prevent a light source from being damaged when such liquid crystal display device is vibrated or dropped. The liquid crystal display device is provided with a liquid crystal cell 2, illuminating means 3 that is located behind the liquid crystal cell 2, and a frame body 4 that supports the liquid crystal cell 2 and the illuminating means 3. The illuminating means 3 includes a light guide plate 9, light sources 13 and 14 that are located so as to face one side face of the light guide plate 9, and a holder 12 that supports the light sources 13 and 14. There is provided a reinforcing member 15 between the light guide plate 9 and the holder 12, and there is provided a shock-absorbing member 16 located on a side face of the reinforcing member 15 and that makes contact with or lies adjacent to the one side face of the light guide plate 9.Type: GrantFiled: December 27, 2006Date of Patent: July 14, 2009Assignee: Epson Imaging Devices CorporationInventors: Taiji Nakagawa, Yuki Muraoka, Takuya Nishimoto, Kensuke Nobeoka

Patent number: 7427155Abstract: A liquid crystal module provides for concave shaped recesses formed in an elastic member along the circumference of a linear light source that is arranged on the side of a light guide, and lamp holders attached to both ends of the linear light source, while ring-shaped hard members are engaged with the recesses. Thus, the hard members serve as a grip against an impact applied to the linear light source, and the linear light source is prevented from being damaged. Accordingly, a sidelight-type liquid crystal module with a liquid crystal panel is thereby obtained, in which the damage to the linear light source (when an impact, or the like, is applied to the liquid crystal panel) is prevented by simple means without affecting the quality of light that is emitted toward the liquid crystal panel.Type: GrantFiled: November 12, 2004Date of Patent: September 23, 2008Assignees: Sanyo Electric Co., Ltd., Tottori Sanyo Electric Co., Ltd.Inventors: Taiji Nakagawa, Seiji Morimoto, Yuki Muraoka

Publication number: 20060164860Abstract: A liquid crystal display device includes a light source and a light guide plate, and further includes, laid successively on top of the light guide plate, a diffusive sheet, a first and a second prism sheet having prism ridges thereof aligned in mutually perpendicular directions, a lower polarizing plate, a liquid crystal cell, and an upper polarizing plate. The first and second prism sheet has the prism ridges thereof aligned in a direction parallel or perpendicular to the row direction of the pixels. The lower polarizing plate has, laid successively downward below the liquid crystal cell, a first adhesive layer, a first transparent film, a polarizing film, and a second transparent film. The first adhesive layer contains a light-diffusing material.Type: ApplicationFiled: January 11, 2006Publication date: July 27, 2006Inventors: Yuki Muraoka, Toyohiro Sakai, Junya Mita, Naohiro Idenishi, Hiroki Sakemoto

Publication number: 20050030581Abstract: Presence/absence of a movement between a first unit-image that constitutes the entire image representing the whole imaging area and a second unit-image that constitutes the previous entire image and that is located in the same imaging direction as the first unit-image is determined. When a movement exists between the first and second unit-images, imaging operations for the next entire image are performed with the imaging direction fixed to the first unit-image and its surrounding unit-images, and the imaged unit-images are recorded in the recording medium.Type: ApplicationFiled: July 8, 2004Publication date: February 10, 2005Inventors: Shoji Hagita, Hideki Hama, Yuriko Tsuchiya, Masae Takeda, Yuki Muraoka
