IPC: G11B5/85
Filed: 1984-04-20
Abstract: PURPOSE:To obtain the titled magnetic recording medium having excellent weather resistance by vapor-depositing a magnetic metallic material on the surface of a moving substrate while changing the incident angle continuously from a high to a low incident angle, and vapor-depositing a nonmagnetic metallic material on the vapor-deposited layer while changing the incident angle continuously from a low to a high incident angle to form a vapor-deposited film. CONSTITUTION:A vapor-depositing material 23 consisting of a metal such as Ni, Co, Fe, etc. or the alloy of said metals is evaporated from a crucible 25 and vapor-deposited on a substrate 21 (1 of another figure) to form an inclined columnar magnetic layer 2 while transporting the strip-shaped substrate 21 of a polyester film, etc. along a cooling can 22 in the direction as shown by the arrow A, and changing the incident angle of the vapor flow continuously from a high to a low incident angle with deposition preventive plates 27 and 28. Then a nonmagnetic metal 24 selected from Cr, Ti, Sn, Cu, and Al is evaporated from a crucible 26 and vapor-deposited to form a nonmagnetic metallic layer 3 while winding reversely the substrate 21 in the direction as shown by the arrow B and again transporting the substrate in the direction as shown by the arrow A, and changing the incident angle continuously from a low to a high incident angle with deposition preventive plates 28 and 29.

Title: Image processing unit and its method
Inventor: FURUKAWA ITARU
IPC: G06T5/20
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration in image quality and to eliminate moire without deteriorating an edge of an image. SOLUTION: A main signal S as to a noted pixel is led to a mean density extract section 10 and a filter arithmetic section 40. Then the mean density extract section 10 extracts a mean density D in an area larger than a dot size and fed to an ID reference table 20. The ID reference table 20 provides an output of a reference value ID in response to the mean density value D. Then a weighting coefficient set selection section 30 decides an effective size of an image filter by selecting a set of a weight coefficient based on the reference value ID. The decided effective size is increased at a density area remarkable in moire. Then the filter arithmetic section 40 conducts calculation based on each weighting coefficient of the image filter obtained by the weighting coefficient set selection section 30 to generate a filtered signal S'.

Title: Communication system
Inventor: RICHARD C WATTERS
IPC: H04L12/70
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To attain very efficient processing and to decrease a band width, a storage capacity and a calculation time. SOLUTION: In order to reduce the band width, the storage capacity and the calculation time required to synchronize data transmitted via an asynchronization communication network 64, when respective data items to be synchronized have only a small short time difference and it is required to make a continuous operation over a long time with highly synchronization precision, a compact modular time stamp T offering very efficient processing is utilized. The band width, the storage capacity and the calculation time are reduced by placing a limit onto both the accuracy and the range of the time stamp T attached to data. Data sampled at a high frequency are grouped in terms of a comparatively low frequency group 68 and a low precision time stamp is assigned to each group so as to limit the precision and a module arithmetic to denote the time stamp is used to limit the range.
