Patent number: 8922912Abstract: A Fresnel lens comprises a first surface, and a second surface being the reverse side surface of the first surface and having a plurality of lens surfaces. Each lens surface is configured from a part of a side surface of an elliptical cone, which has an apex located on the second surface side and a bottom surface located on the first surface side. Here, in the Fresnel lens, any normal line intersecting with the lens surface configured from the part of the side surface of the elliptical cone among normal lines of respective points on the first surface is non-parallel to a central axis of the elliptical cone corresponding to the lens surface with which the any normal line intersects.Type: GrantFiled: January 25, 2013Date of Patent: December 30, 2014Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kana Oi, Takayuki Nishikawa, Kimitake Okugawa, Akira Fukuoka

Patent number: 5742895Abstract: A device used in a multimedia communication system is formed with a transceiver unit for transmitting and receiving information signal to and from the inside of a room and a base unit adapted to be mounted to a wall of the room to detachably support the transceiver unit. The transceiver unit has a plug surface on which a plug projects, a circular wall projecting on the plug surface to surround the plug, and a guide wall projecting on the plug surface inside the circular wall and around the plug. The base unit comprises a disk member which is provided with a receptacle exposed in a receptacle surface defined on the disk member. The disk member has a diameter slightly smaller than an inner diameter of the circular wall so that the disk member can fit within the circular wall when the transceiver unit is attached to the base.Type: GrantFiled: June 21, 1996Date of Patent: April 21, 1998Assignee: Matsushita Electric Works, Ltd.Inventors: Yoshihiro Tanigawa, Shinji Morino, Isao Shimada, Masafumi Morimoto, Koji Ikeda, Sadaaki Kondo, Kimitake Okugawa
