Patent number: 8692941Abstract: A receiving apparatus 10 efficiently receives radio waves used for wireless communication. Four sides of the periphery of a back cover 4 are bent inward. The reflector 5 formed of a metallic material is disposed on the bent portion on the inner side of a housing. When radio waves are transmitted from the front of the receiving apparatus 10, the radio waves are reflected by the reflector 5 disposed on the back cover 4 and are directed toward the inside of the housing. The directed radio waves are received by a radio module 3.Type: GrantFiled: February 4, 2010Date of Patent: April 8, 2014Assignee: Sony CorporationInventor: Shozo Horisawa

Publication number: 20110307726Abstract: A remote controller 10 sets, in step S1, a period of time Tx in which a reception mode is maintained after an instruction is transmitted. A generated instruction is transmitted to a communication module 20 (in step S3). The communication module 20 converts the received instruction into a control signal and transmits the signal to an electronic apparatus 30 (in step S4). After a process is executed in response to an instruction, the electronic apparatus 30 outputs information to be returned to the remote controller 10 to the communication module 20 (in step S5). The communication module 20 transmits information (in step S6). The information is received within the period of time Tx after the instruction is transmitted. Thereafter, the reception mode is cancelled (in step S7). After the reception mode is cancelled, the remote controller 10 returns to a sleep mode and operates with the minimum power.Type: ApplicationFiled: February 19, 2010Publication date: December 15, 2011Applicant: Sony CorporationInventors: Kazunori Kikuchi, Masahiro Nakano, Takashi Tsurumoto, Takayoshi Yamasaki, Shozo Horisawa, Kanahiro Shirota

Patent number: 5384557Abstract: A polarization separator for separating orthogonal polarization waves into a horizontal polarization wave component and a vertical polarization wave component is minimized in size. A metal pole in the form of a thin metal bar is disposed in a circular waveguide of a waveguide member into which the orthogonal polarization waves are introduced, and reflects the horizontal polarization wave component so that it is outputted through an output terminal formed in a circumferential wall of the waveguide member. Meanwhile, the vertical polarization wave component propagates in a substantially rectangular waveguide provided rearwardly of the metal pole and is outputted from another output terminal. Since the rectangular waveguide is formed in a cutoff structure for the horizontal polarization wave component, the reflection means can be formed from the metal pole in the form of a thin bar, and consequently, the polarization separator can be minimized.Type: GrantFiled: November 10, 1993Date of Patent: January 24, 1995Assignee: Sony CorporationInventors: Yoshikazu Yoshida, Kenichi Kawasaki, Shozo Horisawa, Hiroyuki Mita, Keiji Fukuzawa

Patent number: 5248950Abstract: A high frequency signal processing apparatus having signal line patterns formed on the upper surface of a dielectric substrate has a bias line pattern that extends from each of the signal line patterns. The bias line pattern has a first portion formed on the upper surface of the dielectric substrate, a second portion formed on the lower surface of the dielectric substrate, and a conductor extending through the dielectric substrate for providing an electrical connection between the first and second portions of the bias line pattern. A trap pattern is formed on the lower surface of the dielectric substrate and is connected to the second portion of the bias line pattern at a position spaced a predetermined distance away from the corresponding one of the signal line patterns. The predetermined distance is substantially equal to an odd number multiplied by T.multidot..lambda./4 where T and .lambda. are the periodicity and wave-length of the high frequency signal to be processed.Type: GrantFiled: April 14, 1992Date of Patent: September 28, 1993Assignee: Sony CorporationInventors: Shozo Horisawa, Hiroyuki Mita
