Patent number: 8456579Abstract: This disclosure presents an apparatus and method for automatic gain control correction for a television signal in which the Radio Frequency (RF) and Intermediate Frequency (IF) power signal levels are collected for a band of channels, identifying a channel having a strong RF power signal level and an IF gain signal level that is lower than a nominal IF gain signal level, comparing the identified channel RF gain signal level with the RF gain signal level of adjacent channels to identify the relative power signal levels of the channel and associated adjacent channels, and applying correction to the channel wherein there is an imbalance in the RF and IF power signal levels of the identified channel. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.Type: GrantFiled: February 11, 2008Date of Patent: June 4, 2013Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Hiromichi Sano, William Bennett, Liviu Burciu

Patent number: 6678011Abstract: A band-pass filter separates an audio intermediate frequency signal from an input intermediate frequency signal, and an A/D converter circuit converts the audio intermediate frequency signal into a digital signal. A DSP performs audio detection on the digital signal and forms an AGC signal based on the signal. A variable gain amplifier performs AGC on the audio intermediate frequency signal in response to the AGC signal. A bandpass filter separates and takes out a video intermediate frequency signal from the signal, and an A/D converter circuit converts the video intermediate frequency signal into a digital signal. A DSP performs video detection on the signal. An AGC signal is formed based on the signals and AGC is performed on the video intermediate frequency signals by using the AGC signal.Type: GrantFiled: April 26, 2001Date of Patent: January 13, 2004Assignee: Sony CorporationInventors: Shigeto Yanagi, Toshiyuki Nagano, Hiromichi Sano, Takayuki Kaida

Patent number: 4931340Abstract: A honeycomb panel structure for thermal and acoustic insulation and for load bearing capability has a honeycomb panel which comprises a honeycomb core laminated with two facing plates, and a pair of housings. Each housing has a channel to engage and support a edge of the honeycomb panel. A first neutral axis passes through the center of gravity of the honeycomb panel and extends in the direction of the panel. A second neutral axis passes through the centers of gravity of the housings and extends parallel to the first neutral axis. The first and second neutral axes are spaced apart in a vertical direction so that the structure has much higher flexural rigidity.Type: GrantFiled: December 22, 1986Date of Patent: June 5, 1990Assignee: Sumitomo Light Metal Industries, Ltd.Inventors: Takeaki Baba, Keizo Nanba, Yoshio Takeshima, Hiromichi Sano, Koji Tobita, Atsuo Muneto, Toshihiro Hara, Kazuki Fujise
