Patent number: 8182305Abstract: Provided is a manufacturing method to prevent devitrification of a bulb in a high pressure discharge lamp used for a projector. The method is for manufacturing a high pressure discharge lamp which uses, as a light source, a bulb made of fused quartz and including a tungsten electrode, and which is horizontally installed when the lamp is driven for actual use. The method includes the step of initially driving the bulb with an optical axis thereof being set horizontally before the high pressure discharge lamp is shipped. In the initial driving step, the rotation angle around the optical axis of the bulb is offset by 45° or more and 135° or less relative to the rotation angle around the optical axis of the bulb when the lamp is driven for actual use.Type: GrantFiled: June 9, 2009Date of Patent: May 22, 2012Assignee: Iwasaki Electric Co., Ltd.Inventors: Toshio Yoshizawa, Katsuhiro Okabe, Makoto Ohkahara, Nobuo Fukuda, Shigeharu Sato, Shinichi Takemasa

Patent number: 7502294Abstract: Information recording and playback apparatus, content management method, and content management program. When data of copyright-protected content is recorded in a general-purpose HDD, illegal copying of the content is prevented. Each time when content is recorded in the HDD and when content recorded in the HDD is moved to a Blu-ray disc (BD), a random number output section outputs unique verification information (a random number) and overwrites the unique verification information in the corresponding verification files of the HDD and an EEPROM. Then, when the content recorded in the HDD is to be moved to the BD, a verification section verifies the verification information (random number) recorded in the verification file of the HDD against the verification information (the random number) recorded in the verification file of the EEPROM, and permits the movement of the associated content only when they match.Type: GrantFiled: March 24, 2005Date of Patent: March 10, 2009Assignee: Sony CorporationInventors: Susumu Senshu, Shigeharu Sato

Patent number: 5886654Abstract: Decoding apparatus and method set interpolation flags in units smaller than an ECC block. The PI1 flag indicating an error on a row-by-row basis is generated for the first error correction result, while the PI2 flag also indicating an error on a row-by-row basis is generated for the second error correction result in the ECC block. The PO flag indicating an error on a column-by-column basis is further generated for the error correction result in the ECC block. Following these processing operations, the PI1, PI2 and PO flags are used for generating the interpolation flags.Type: GrantFiled: July 31, 1997Date of Patent: March 23, 1999Assignee: Sony CorporationInventors: Takahiro Ichikawa, Kazuhiro Yasuda, Tadashi Nakata, Shigeharu Sato
