Patent number: 7871156Abstract: An ink cartridge for an ink jet printer having a housing having at least one wall. The ink cartridge further has at least two ink chambers for containing different ink accommodated in the housing. Ink supply ports are formed in one wall of the housing within each of the ink chambers. Each of the ink supply ports has an inner opening and an outer opening.

Publication number: 20080284833Abstract: A method for sealing an ink cartridge is disclosed. A cover film is bonded to the ink cartridge in such a manner as to cover an ink inlet hole formed in the ink cartridge. An opening is formed in the cover film in such a manner as to communicate with the hole of the ink cartridge. The method includes preparing a seal film and bonding the seal film to the cover film with a bonding strength smaller than the bonding strength of the cover film with respect to the ink cartridge in such a manner that the seal film becomes peelable from the cover film, thereby sealing the opening of the cover film.Type: ApplicationFiled: May 2, 2008Publication date: November 20, 2008Applicant: SEIKO EPSON CORPORATIONInventors: Yasunao UEHARA, Yuichi Seki, Masahide Matsuyama, Yasuhiro Ogura

Patent number: 6941333Abstract: A normalizer normalizes the power of a dither signal calculated by a power calculator based on the average power of a PCM signal in the range of 18 kHz to 20 kHz, wherein the average power is calculated by the power calculator. An oversampling processor oversamples the PCM signal with a quantization frequency of 44.1 kHz and a quantization word length of 16 bits, wherein the PCM signal is inputted from an input terminal at a sampling frequency of 2×44.1 kHz, and then supplies an output of the oversampling process to an adder. The adder adds the normalized output from the normalizer to the oversampling output from the oversampling processor, and then supplies the addition output to an oversampling processor.Type: GrantFiled: February 20, 2002Date of Patent: September 6, 2005Assignee: Sony CorporationInventors: Makoto Akune, Yasuhiro Ogura
