Publication number: 20120092309Abstract: It is a main object of the invention to provide an image display device and an information processing device that can be incorporated in the computer main body of a notebook computer, etc., and can project an image at any desired angle when the image is projected onto a screen. To accomplish the object, the invention provides an image display device including a first unit for storing an optical system for displaying an image on a screen and a second unit for storing a control board for controlling the optical system, electrically connecting to the first unit, and holding the first unit for rotation. The first and second units are housed in a housing space formed in an information processing device. When the image is projected onto the screen, the first unit is completely exposed from the information processing device and at least a part of the second unit is stored in the information processing device.Type: ApplicationFiled: February 28, 2011Publication date: April 19, 2012Applicant: PANASONIC CORPORATIONInventors: Nobuo JIKUYA, Hitoshi FUJIMOTO, Kazumi OHTSUBO, Yoshitaka KITAOKA, Munenori AOYAGI, Ryousuke ARAKI

Patent number: 5444474Abstract: An ink-jet cartridge for ink-jet printers includes a nozzle-cleaning mechanism built in the cartridge itself for removing residual ink and foreign matter, such as dust and dirt including paper powder, from nozzles. Since the built-in nozzle-cleaning mechanism is replaced automatically when the cartridge is replaced, and since the replacement of the cartridge generally takes place before the nozzle-cleaning mechanism deteriorates mainly due to contamination with ink, the nozzles are always kept clean and a reliable printing operation with high quality printing is insured throughout the service life of the cartridge.Type: GrantFiled: March 19, 1993Date of Patent: August 22, 1995Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazumi Ohtsubo, Mitsuhide Matsuda, Yutaka Miyazono, Hideaki Horio
