Title: Dedicated optical disk for high density reproducing
Inventor: AHN YOUNG-MAN
IPC: G11B7/24079
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain a high density optical disk by continuously forming plural grooves along each track in a waveform manner, providing plural information pits to the grooves and making possible to reproduce the information from the track pits which are narrower than the track pits of the optical disk having only information pits for every track. SOLUTION: Information pits 4 are continuously formed in grooves 6 which are continuously formed along each track of a digital video disk(DVD) by the laser beam recording of a mastering process. The waveformed grooves 6 reduce the angle of the 1st-order diffracted light beams of the incident light beams from a substrate 2. The beams are made incident on the light receiving region of the lens of a pickup and a tracking servo is made possible. The grooves having a depth of 'd' scatter the information signals from the adjacent tracks. However, if a track pit P is 0.50 μm, optimum tracking error signals are obtained when 'd' is set to 25 mm. Thus, a high density DVD, which is reproducible, is realized using a conventional DVD reproducing device.

Title: Forming of resist pattern shaped like inverted truncated pyramid
Inventor: TSUGE HISANAO
IPC: H01L21/027
Filed: 1978-08-28
Abstract: PURPOSE: To raise the accuracy of lifting-off, by coating a resist on a substrate, performing heat treatment under such conditions before exposure that the surface part of the resist is provided with a heterogenous layer of lower development speed than the internal part of the resist, and performing excessive etching in development.  
     CONSTITUTION: A resist pattern 31 is made on the substrate 11. A film 32 of Al, Au, Ti, Cr or the like is coated on the resist pattern 31 and the substrate 11 by evaporation, ion beam deposition or the like with flying atoms or molecules of directivity. The pattern 31 is then partly removed together with the upper film 32 by a removing liquid so that another pattern 33 is made of only the film 32 coated on the substrate 11. To effect this process, each part of the resist pattern 31 must be shaped like an inverted truncated pyramid. Therefore, the resist is previously baked at a higher temperature for a longer time than in conventional cases to decrease the development speed of the resist toward the surface. Each part of the resist is thereafter excessively etched to the form of the inverted truncated pyramid.

Title: Ink jet printing machine
Inventor: DEEBITSUDO JIEI ROGAN
IPC: B41J2/005
Filed: 1985-05-17
Abstract: An ink jet printing system suited to the making of large scale graphics, such as outdoor billboards, includes an endless carrier for moving a plurality of rigid flat panels, onto which a graphic is to be printed in sections, repetitively past an ink jet printing station. At the printing station each panel moves in purely rectilinear fashion in a direction parallel to its ink drop receiving face so that such face remains essentially at a uniform spacing from the ink jet printing heads of the printing station as the printing occurs. A means for timing the operation of the ink jet heads takes into account irregularities or changes in the motion of the panels past the printing station so that the ink drops are correctly placed despite such irregularities or changes. The ink jet heads can eject relatively large drops of pigmented ink. In the case of polychromatic half-tone printing, for each pixel of a panel different colors are printed at substantially different times so that the printed ink drops of one color can dry before those of another color are printed, and a heating means may be used to enhance the drying.

Title: Shared memory duplex system

Abstract: PURPOSE:To change over the control to a subsystem at the time of the failure of a main system without providing a system auditing device, etc., by writing the data, in which the main system is periodically updated, into a shared memory, reading periodically this by a subsystem and inspecting the updating. CONSTITUTION:A main system 1 writes a data value updated each time without fail, for example, a timer value, into the prescribed area of a shared memory periodically. A subsystem 2 reads the data at the interval of the period longer than the period written by the main system 1, and the data are read and the updating is inspected. Since the data are read at the period longer than the writing period of the main system 1, it is natural that when the writing of the main system 1 is normal, the reading data are different from the previous reading data without fail. When the data value of the same contents is continuously read, it is decided that the data are stopped due to the occurrence of a hardware defect or the data are hung up due to the software defect, and therefore, the data cannot be updated to a condition information area periodically.

Filed: 1979-08-20
Abstract: PURPOSE: To accurately analyze chromium through simple operation, by charging a sample alloy into a carbon burner and supplying oxygen at a prescribed temperature to burn off the carbon in the alloy and oxidize its chromium and iron.  
     CONSTITUTION: A sample alloy S is charged into a carbon burner A. Oxygen is supplied as the temperature of the alloy is maintained at 650W700°C. As a result, the carbon in the alloy is burned off and its chromium and iron are oxidized. It is preferable to previously pulverize the alloy to about 250W350 mesh. According to this method, even an alloy containing 2% or more by weight of carbon and 3% or more by weight of chromium, some of which is present in the form of a carbide which cannot be dissolved by acid, alkali and a melting agent, can be easily molten by the melting agent after the treatment as mentioned above. Accurate analysis is thus enabled.
