IPC: G06T1/60
Filed: 1990-08-27
Abstract: PURPOSE:To allow the change of display data in a horizontal blanking period without participation of a CPU by executing data transfer by a 1st data transfer means in response with a horizontal blanking signal. CONSTITUTION:The operations of H-DMA include the H-DMA table processing V to be executed right after the start of a display period, the H-DMA data processing to be executed right after the start of the horizontal blanking and the H-DMA table processing H to be executed right after the processing. The CPU 12 in the H-DMA table processing V writes various set parameters; for example, a transfer direction, addressing mode, B bus mode, etc., in the set parameter region within a DMA working memory prior to the data transfer in the H-DMA data processing to be executed right after the start for the H blanking period. The work area for counting the line number of the DMA working memory is decremented and the processing is executed according to the result thereof in the H-DMA table processing H.

Title: Analog/digital converting circuit
Inventor: KOBAYASHI AKIRA
IPC: H03M1/66
Filed: 1983-11-30
Abstract: PURPOSE:To obtain a D/A converting circuit which is suited to a PCM signal generator by using an aperture signal generating circuit containing a small number of component parts to always obtain the coincidence between the ratio between the sampling cycle and the aperture time and the set value to the variation of the sampling cycle. CONSTITUTION:The set value (n) is defined for the ratio between the sampling cycle and the aperture time of an aperture signal generating circuit 46. In this case, the DC voltage VINTG obtained by integrating the output APTCLK of a monostable multivibrator 33 is shown by figures (a) and (b). Therefore the reference voltage VR of an error amplifier 39 is set equal to the VINTG. Thus the set ration (n) is decided by reference voltage setting resistances 40 and 41. If the sampling cycle changes to TSD from TSphi as shown by a figure (c), the (n) is reduced to satisfy VINTG<VR as shown by a figure (d). In this case, the amplification output voltage V0 of the error voltage VINTG-VR<0 is reduced more than that obtained before the sampling cycle is increased. Then the electrostatic capacity CX of a voltage variable capacity diode 44 increases. As a result, the external timing capacity CT of the vibrator 33 increases together with the output pulse width of the vibrator 33. Then the TINTG increases to maintain a prescribed ratio (n).

IPC: G01D5/38
Filed: 1989-08-31
Abstract: PURPOSE:To make it possible to maintain the visibility of an interference pattern effectively with a simple structure by inserting an adjusting member between a point light source and an encoder plate constituting a one-dimensional diffraction grating. CONSTITUTION:An adjusting member 7 is inserted between a point light source 1 and a displacement slit member 3. When a coherent spherical surface wave is projected on the rotating displacement slit member 2 from the point light source 1, an interference pattern 4 is formed on a fixed slit member 5. A space filter having a space period corresponding to the period of the pattern 4 is formed in the member 5. The diffracted light passed through the space filter is received with a photodetector 6 and converted into a detected signal. Since the member 7 is inserted between the point light source 1 and the member 3, the clear diffraction pattern is obtained all the time by adjusting the apparent light path between the point light source 1 and the member 2.

Title: File copy system
Inventor: KAMEGAYA YUKIO
IPC: G06F12/00
Filed: 1989-08-30
Abstract: PURPOSE:To prevent such useless copying processes of files that are carried out when both input and output files have the same contents or the output file is later than the input file by comparing the final updating date of the input file with the latest updating date of the output file when the coincident is obtained between the names of the input and output files when these files are copied. CONSTITUTION:The coincidence is checked between the names of read input and output files. When the coincidence is secured between both names, a file copy program 21 acquires the final updating date of an input file 3 from a date store area 32 via an operating system 22. Then the program 21 acquires the final updating date of an output file 4 from a date store area 42 via the system 22. These two updating dates are compared with each other. If the file 3 is later than the file 4, the contents of the file 3 are read via the system 22 and written into the file 4. Thus no copying process is carried out when the contents of both files 3 and 4 are equal to each other or the file 3 is updated to the file 4. As a result, the file processing efficiency is improved and the wrong copying processes can be prevented.

Title: Recording medium
Inventor: ISHIKAWA KEIKO
IPC: G03F7/09
Filed: 1991-09-06
Abstract: PURPOSE:To eliminate the trouble of replacing a recording medium according to the purpose of use by coating a transparent base with a thermosensitive body which reversibly varies in transparency depending upon the temperature or mixing the heat sending body with the transparent base. CONSTITUTION:The transparent base 2 is coated with the thermosensitive body 3 which reversibly varies in transparency depending upon the temperature. The thermosensitive body 3 is in a white turbid opaque state at room temperature below, for example T0, and becomes transparent when heated up to T1-T2 and holds itself transparent even after the temperature is put back to the room temperature. The thermosensitive body becomes translucent when heated from T2 to T3 and is put back into the white turbid opaque state when the temperature is lowered. When the thermosensitive body is heated up to T0-T1 and then cooled below T0, transparency between the transparent state and opaque state is obtained. Even when the thermosensitive body is transparent at the room temperature, the body is put back into the white turbid opaque state again by being heating above T3 and cooled to the room temperature. Thus, the thermosensitive body 3 is put in the transparent state, opaque state, and intermediate state at the room temperature. An image on the base 2 can, therefore, be viewed with transmitted light or reflected light.
