A first recording layer for recording information of an optical disk and a second recording layer of the optical disk on which a visible image can be recorded are disposed at an interval of 0.5 mm or more. Thus, even when a high power laser is used on one of the layers, data on the other layer will not be destroyed.

Optical disk and optical disk device

There is provided a small-sized and light-weight image display apparatus which is thinned in the line of sight and which incorporates a display unit for displaying a magnified virtual image and a direct image, the display apparatus comprising a real image display part for displaying an image, an image magnifying means for optically magnifying the image formed in the real image forming means so as to form a virtual image, and a light guide means for guiding light from the real image display part to the image magnifying means, the magnifying means being formed in a triangular columnar shape having a substantially isosceles triangular cross-section, and having a first surface serving a light incident surface, a light emanating surface and a reflective surface, and a first internal reflecting surface and a second internal reflecting surface for reflecting light into the light guide means, wherein emanating light from the real image display part is incident upon the light guide means through the first surface, and is then reflected by the first internal reflection surface and the second internal reflection surface, and thereafter, the light emanating from the light guide means and entering into the image magnifying means.

A thin type ink jet cartridge consists of a passageway for holding ink, a thin type ink holder made of transparent material for accommodating the passageway, a graded scale put on the thin type of ink holder to quantitatively check the volume of the ink held in the passageway, ribs for structurally reinforcing the thin type ink holder, nozzles for discharging the ink held in the passageway at a recording paper, a shutter for covering the shutter when the ink is not discharged from the nozzles, a protecting plate for protecting the recording paper from contact with the nozzles by surrounding the nozzles positioned at a concave portion surrounded by the protecting plate.

A method for manufacturing an ink jet head which involves the steps of casting a first synthetic film on a metal film, etching the conductive metal to produce a pair of etched electrodes facing each other across an opening according to lithography and etching techniques, casting a second synthetic resin film being transparent on the etched electrodes and the first synthetic resin film, ablating both the first and second synthetic resin films with an excimer laser without damaging the electrodes to form both an expelling nozzle which penetrates the second synthetic resin film and an ink passageway which penetrates the first synthetic resin film through the opening, attaching an ink holding cap to the first synthetic resin film to hold conductive ink in a hollow portion thereof, and electrically connecting the etched electrodes with a voltage generator through electrical leads for applying a voltage generated in the voltage generator to the etched electrodes, wherein the etched electrodes project into the expelling nozzle. The conductive ink held in the ink holding cap is expelled from the nozzle through the ink passageway upon vaporization.

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.
