摘要:
For a plurality of digital video signals whose frame frequencies are different, a pixel number converting circuit to convert the number of pixels is provided so that differences of the frame frequencies are replaced to differences of the numbers of pixels and a plurality of digital video signals whose frame frequencies are different can be processed by a common clock frequency. The frame frequency is detected by a frame frequency value decoder and the number of pixels in the horizontal direction of the pixel number converting circuit is properly set in accordance with the frame frequency. As mentioned above, if the differences of the frame frequencies are replaced to the differences of the numbers of pixels and the images are converted into the image in which the frame frequencies are the same and the numbers of pixels are different, the frame frequencies are equalized and the signals can be processed by the same clock.

摘要:
A method of manufacturing a magnetic recording medium that includes a nonmagnetic underlayer, a magnetic layer, a protective layer, and a lubricant layer sequentially laminated on a nonmagnetic substrate. The method includes applying a lubricant onto the protective layer to form the lubricant layer, which includes ejecting shots of a heated lubricant liquid onto the protective layer from a nozzle. The heated lubricant liquid contains a perfluoropolyether lubricant, and each shot is of a quantity in a range of 0.1 to 10 pico liters.

摘要:
A method to refine a lubricant on a magnetic recording medium includes a compound A including a perfluoropolyether molecular structure having two hydroxyl groups at each of two ends and a compound B including the perfluoropolyether molecular structure having one hydroxyl group at each of two ends. The method includes putting the lubricant into a pressure vessel set at a pressure and a temperature and removing the compound B dissolved in an extracting medium of a supercritical carbon dioxide fluid that flows at a predetermined rate through the pressure vessel held at a predetermined temperature and at a predetermined pressure. The method performs recovering the compound A dissolved in the extracting medium that flows through the pressure vessel held at the predetermined pressure and at a temperature lower than the predetermined temperature or at the predetermined temperature and at a pressure higher than the predetermined pressure.
