Title: Ink cartridge, printing head and ink jet printer
Inventor: NAGASAKI YOSHIKI
IPC: B41J2/175
Filed: 1994-12-28
Abstract: PURPOSE: To prevent the intrusion of foams into a chamber at the time of setting and removing an ink cartridge and carry out the printing of high reliability by providing a valve means in which a connecting section is opened by inserting an ink jet feed pipe into the connecting section to communicate a printing head with a second chamber. CONSTITUTION: A valve 18 is pressed by an end of a feed pipe 2 and distorted to eliminate a space between the valve 18 and the end of the feed pipe 2. As the shape of a packing 19 corresponds to the shape of the end of the feed pipe 2, no air remains in the vicinity of the valve 18 and the feed pipe 2, and the intrusion of foams into a chamber 13 of an ink cartridge 11 is not generated. The tapered shape of the end of the feed pipe 2 corresponds to the tapered shape of an opening on the lower section of the packing 19, while the lower section of the valve 18 and the upper section of the packing 19 are formed respectively into the half-spherical shape protruded downward and the half- spherical shape recessed upward.

Title: Optical information recording medium
Inventor: SUZUKI MASARU
IPC: G11B7/24
Filed: 1988-12-28
Abstract: PURPOSE:To suppress increase of noise caused by repetition of recording and erasing and to improve reliability of data readout by providing the same type of stress in a protective layer as the stress in an optical recording layer. CONSTITUTION:A protective film having the same type of a stress as in the optical recording layer is provided on at least one side of the optical layer. If the optical recording layer has tensile stress, the protective layer is provided with tensile stress. If the optical recording layer has compressive stress, the protective layer is provided with compressive stress. Thereby, stress generating in the interface area of the optical recording layer and the protective layer is reduced to suppress the strain caused by repetition of recording and erasing.
