Abstract: PURPOSE:To increase the number of gradation control by controlling an output voltage by using the pulse width shown by the analog time quantity which is obtd. by using the sample-held analog voltage for gradation and controlling the modulation of the analog pulse width. CONSTITUTION:A sample-hold circuit 3 is channel-selected by a select signal and sample-holds the gradation data according to a timing pulse. The captured gradation data is taken into a switching circuit 4 according to the select signal. The gate by an AND gate circuit 6 is thereafter opened at the point of the time when all the data are captured. The captured data and a reference ramp voltage Vramp 14 are then compared and the gradation data (PWM control pulse) subjected respectively to the analog pulse width modulation are supplied to respective V/I conversion circuits 7. Namely, the gradation control of the display by using the pulse width indicated by the analog time quantity is analogically executed by sample-holding the gradation data. The number of the gradation control is increased in this way.

IPC: G11B5/667
Filed: 1987-12-21
Abstract: PURPOSE:To improve reliability to recording and reproduction by constituting a nonmagnetic substrate of a superconducting material and maintaining the substrate at the temp. below the critical temp. to completely shut off the leak-in of external magnetic fields. CONSTITUTION:This recording medium is constituted by laminating a soft magnetic lining layer 13 and a perpendicularly magnetized recording layer 14 successively on the superconductive substrate 31. The layer 14 has the axis of easy magnetization perpendicular to the layer 13. The substrate 31 of the perpendicular recording medium constituted in such a manner has the complete diamagnetism to entirely prohibit the infiltration and transmission of the external magnetic fields into and through the substrate when the substrate 31 is maintained at the temp. below the critical temp. at the time of recording and reproducing. The magnetization of the main magnetic pole of a magnetic head by the concentration of the external magnetic fields to the lining layer 13 is thus prohibited. The demagnetizing and erasing of the magnetic information of the recording medium are thereby prevented and the reliability to recording and reproduction is improved.

Abstract: PURPOSE:To miniaturize the recorder by a method wherein a first application means applying energy for recording a visual image and a second application means applying energy for erasing the visual image are selectively applied to a recording material. CONSTITUTION:A recording medium 1 has a shielding layer 6 such as a metallic thin film layer or the like, a recording layer 7 showing reversibly both transparent and cloudy states, and a protective layer 8 on one surface of a base material 5.

The water is infiltrated in the crack developed in the scribed groove 2, resulting in enlarging the crack by chemical reaction. The phenomenon that the water infiltrated in the crack develops chemical reaction is continued.  As a result, a cutting edge turned to be normal to the board 1 or runs in the direction of the thickness of the board 1, resulting in realizing the cutting of the board 1 with high dimensional accuracy.
