Patent number: 7593072Abstract: An object of the present invention is to provide a display device that can be manufactured more easily than the conventional one. To accomplish this object, an image control panel part (7) which is continuously provided with combination base units including optical transparency base units and optical no-transparency base units, and a lens film part (6) which is continuously provided with repeating units of lenses (8) are laminated in a direction of light transmission, and either one width of the optical transparency base unit or a pitch of the repeating unit of the lens is set so as to be the integral multiplication of the other width. Since the moiré´ fringes can be prevented by setting either one width of the optical transparency base unit or the pitch of the repeating unit of the lens 8 so as to be the integral multiplication of the other width, it is not always necessary for the display device of the present invention to change a pitch of the mold for manufacturing the lens film part 6 randomly.Type: GrantFiled: January 7, 2005Date of Patent: September 22, 2009Assignee: Suntechopt CorporationInventors: Yoshiharu Kanatani, Yukio Shimamura

Patent number: 7310117Abstract: When a time code signal corresponding to an image signal, to which a format conversion changing the number of frames per second is executed, is transmitted, information indicating a frame position where image data is changed through the format conversion in the image signal is attached to the time code signal to be transmitted. Alternatively, information indicating a synchronous state between frame conversion cycles in the format conversion and time code progression is attached to the time code signal. In the foregoing manner, a relationship between the frame position and the time code can be accurately grasped. Further, a secondary conversion (inverse conversion) is accurately executed to the image signal by means of the time code signal.Type: GrantFiled: March 13, 2003Date of Patent: December 18, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takaharu Hosoda, Katsuji Uro, Yukio Shimamura, Masaji Ueno

Patent number: 7151806Abstract: The present invention comprises the step of reading a check-receiving data included in a transmitted time code signal and using the read check-receiving data to generate a transmitting side checking data, and the step of attaching the transmitting side checking data to the transmitted time code signal, as a pre-processing step at the time of transmitting the time code signal. The present invention comprises the step of reading the check-receiving data from the received time code signal and using the read check-receiving data to generate a receiving side checking data, and the step of reading the transmitting side checking data from the received time code signal and comparing the read transmitting side checking data to the receiving side checking data, thereby verifying whether or not an error is generated in the received time code signal. In this way, an error can be detected in the time code signal, as a post-processing step after the time code signal is received.Type: GrantFiled: March 13, 2003Date of Patent: December 19, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takaharu Hosoda, Katsuji Uro, Yukio Shimamura, Masaji Ueno

Patent number: 7146558Abstract: As a pre-processing step for transmitting a timecode, a checking information is retrieved from a linear time code (LTC). A checking data is created using the retrieved checking information. The checking data is superimposed on a vertical interval time code (VITC). As a post-processing step for transmitting a timecode, meanwhile, collating information corresponding to the checking information is retrieved from the LTC. A collating data is created using the retrieved collating information. Then, the checking data is retrieved from the received VITC. The retrieved checking and collating data are collated to verify, thereby, the presence or absence of errors in the received LTC.Type: GrantFiled: November 5, 2002Date of Patent: December 5, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yukio Shimamura, Toru Yamashita, Akiyuki Noda

Patent number: 4622640Abstract: A power load survey apparatus is disclosed with an electronic power sensor for detecting a power load in the form of a pulse signal, a collector cartridge detachably coupled to the electronic power sensor and having a memory for storing the pulse signal and the time of data collection. The time is obtained from a self-contained time keeping circuit. A memory and magnetic tape converting device is detachably coupled to the collector cartridge and includes a magnetic tape device for transferring and recording data from the memory of the electronic power sensor, and a standard clock 52. The time data obtained from the collector cartridge is time rectified to a standard time from the standard clock 52 each time the collector cartridge is coupled to the memory/magnetic tape converting device thereby insuring that the collector cartridge shows a correct time.Type: GrantFiled: July 25, 1983Date of Patent: November 11, 1986Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Yukio Shimamura, Yoshihiro Tsukuda, Ikuo Maeda
