Patent number: 11503246Abstract: A video output controlling apparatus and a video output controlling method that can reduce the possibility that a video for which encryption is required may be outputted in a non-encrypted state are provided. A first acceptance unit (40) accepts a video and an encryption necessity signal indicative of whether or not encryption of the video is required via a first route. A second acceptance unit (44) accept a control signal via a second route different from the first route. A video conversion unit (46) converts, in accordance with the control signal, the video accepted by the first acceptance unit (40) into one of a video that is different in a format from that of the video and is in an encrypted state and a video that is different in a format from that of the video and is not in an encrypted state.Type: GrantFiled: August 6, 2018Date of Patent: November 15, 2022Assignee: SONY INTERACTIVE ENTERTAINMENT INC.Inventors: Koji Yanaba, Kousuke Yoshimura, Yuji Kawamura

Patent number: 10271007Abstract: A video output apparatus that outputs video data in a first format to a conversion apparatus that converts and outputs the received data in the first format into data in a second format. The conversion apparatus sequentially outputs a blank signal, a vertical synchronization signal, and a blank signal. The video output apparatus includes a frame image data output unit that outputs the first frame image data to the conversion apparatus, a blank signal output unit that outputs a blank signal to the conversion apparatus, and a trigger signal output unit that outputs, to the conversion apparatus, a trigger signal to be converted into a vertical synchronization signal by the conversion apparatus.Type: GrantFiled: April 23, 2018Date of Patent: April 23, 2019Assignee: SONY INTERACTIVE ENTERTAINMENT INC.Inventors: Koji Yanaba, Kousuke Yoshimura, Yuji Kawamura

Patent number: 7343715Abstract: A sound-proof wall made of FRP in the form of a sound-proof wall panel that includes a core and skin members made of FRP positioned on both sides of the core and whose weight per nit area is within the range of 10-60 kg/m2; and a method of producing the same. This sound-proof wall, though light in weight, has a superior sound insulation property and will never corrode because it is made of FRP. Further, it has a high degree of freedom of engineering design including sound-proof property, design, and shape, capable of producing a desired sound-proof wall with case. Further, since it has a high specific strength, it is possible to attain a drastic weight reduction while retaining the necessary strength, and facilitate working, shorten construction time, and reduce construction cost.Type: GrantFiled: May 15, 2002Date of Patent: March 18, 2008Assignee: Toray Industries, Inc.Inventors: Toshihiro Ito, Yutaka Ochi, Toru Kato, Hiroshi Odani, Shintaro Tanaka, Kousuke Yoshimura, Atsushi Ochi, Kimio Mitani

Patent number: 6845022Abstract: A power conversion apparatus of this invention includes a power switching device, a voltage sensor, a current sensor, and a device controller connected to the switching device, the voltage sensor, and the current sensor. The voltage sensor detects an output voltage of the switching device to output a first signal depending on the output voltage, and the current sensor detects an output current of the switching device to output a second signal depending on the output current. The device controller includes a driver connected to the switching device and a correcter connected to the driver, the voltage sensor and the current sensor. The driver outputs a third drive signal to the switching device. The correcter monitors a switching loss and a surge voltage by using the first and second signals, and corrects the third signal depending on values of the switching loss and the surge voltage.Type: GrantFiled: October 2, 2003Date of Patent: January 18, 2005Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kousuke Yoshimura, Noboru Miyamoto
