Filed: 1982-02-10
Abstract: PURPOSE:To simply input a pattern to a screen by cutting out an optional pattern from a plate made of a material which does not penetrate light and indicating one point in the pattern with a light pen having a border detecting part. CONSTITUTION:A measure 4 produced by cutting out a pattern from a board made of a material which does not penetrate light to a picture is put on the picture and one point 5 on the center of the pattern is inputted by a light pen 1. Consequently, luminance on the whole picture is scanned from the detected coordinates to all directions. At that time, light 7 reflected by one point of the picture is projected in all directions and one part of the projected light is inputted to a border detecting part 3 of he light pen 1, so that the detecting part 3 detects that the point is not hidden. On the other hand, the luminance of light 9 from a hidden part 8 does not reach the border detecting part 3 of the light pen 1, so that it is detected that the point concerned is hidden. Thus a border 10 is found by scanning all directions from one point inputted by the light pen 1.

Title: Data transfer system
Inventor: OKU NAOKO
IPC: G06F13/28
Filed: 1990-01-30
Abstract: PURPOSE:To shorten the data transfer time by providing a state reading part and a direct memory access controller DMAC and ordering the state reading part to always read the transfer preparatory state of an input/output part with hardware and to perform the DMA transfer of data. CONSTITUTION:A state reading part 6 starts with a start instruction given from a computer (CPU) and always reads the transfer preparatory state of an input/output part 4 with hardware. Then the part 6 sends a DMA request signal to a DMAC 5 when reading a fact that the preparation is completed for transfer of n-bit data. Thus the DMAC 5 detects the request signal and performs the DMA transfer of data between the part 4 and a memory part 3. When this transfer is through, the DMAC 5 sends a transfer end signal to the part 6. Both the part 6 and the DMAC 5 repeat these operations to repeat the DMA transfer of data. Then the part 6 informs the CPU of the end of the transfer when it reads a fact that the transfer of all data is over. Then the CPU ends the operation of the part 6. Thus the data transfer time is shortened.

Abstract: PROBLEM TO BE SOLVED: To display a picture with a reduced boundary reflection amount and high quality having excellent contrast by providing a polarization light rotary board that selects a polarization light direction in a 1st or 2nd direction to a display device so as to be in close contact with its flat display screen and selecting the polarization light direction of the polarization light rotary board synchronously with display of a picture on the display device. SOLUTION: A changeover control circuit 6 selects a linearly polarized light direction of a passing light of a liquid crystal polarization rotary board 20 in a vertical or horizontal direction in interlocking with a displayed picture on a CRT 10 on the basis of a vertical synchronizing signal from a signal supply circuit 4. The liquid crystal polarization rotary board 20 is closely fixed to a glass tube display screen 31 of the CRT 10 so as to prevent an air layer from being produced between the display screen 31 and the liquid crystal polarization rotary board 20. Thus, an external incident light is reflected on a surface of the liquid crystal polarization rotary board 20 and a contact face between the glass tube 30 and the liquid crystal polarization rotary board 20 only.  Thus, multiple reflection due to intervention of an air layer is suppressed and a picture with high quality where contrast, color purity and resolution are excellent can be displayed.

Filed: 1992-02-05
Abstract: PURPOSE:To provide the manufacturing method of a magnetic recording medium wherein a lubricative film can be held for a long time and a wear-resistant characteristic (a CSS test property) is not lowered. CONSTITUTION:In the manufacturing method of a magnetic recording medium, the magnetic recording medium is provided with the following on a substrate 1: a carbon protective film 4 which protects a magnetic recording layer 3; and a perfluoroalkyl-polyether-based lubricative film 5 formed on it. The manufacturing method is featured in such a way that, after the lubricative film 5 has been formed, the lubricative film 5 is baked under a temperature condition of 100 to 160 deg.C. Since the baking temperature is set to be low as compared with that in conventional methods, the bonding power of the carbon protective film 4 to the lubricative film 5 can be set to a proper state. As a result, said carbon protective film 5 is hard to strip together with the lubricative film 5, and the lubricative film 5 can hold a little fluidity. A lubricant can be supplied from other parts to the exfoliation part of the lubricative film 5, and its wear- resistant characteristic (a CSS test property) can be enhanced.
