Title: Information recording method
Inventor: YAMAMOTO RYOICHI
IPC: G11B9/07
Filed: 1992-08-19
Abstract: PURPOSE:To attain high speed information recording impressing a voltage over an avalanche breakdown voltage to a depletion layer of a semiconductor layer of a medium. CONSTITUTION:An information recording medium 10 is fixed to a turntable 20 by an air chuck or the like, and a moving stylus electrode 21 is used for a voltage impression electrode at recording. When a voltage is impressed from a pulse power supply 25, an organic ferroelectric substance being an opposite part to the electrode 21 is polarized in a prescribed direction to record information. Since a depletion layer is produced in the semiconductor layer corresponding to the part where the polarization is directed downward, a change in a static capacitance is detected by a pickup circuit to read recording information. Since the polarization inversion speed is increased, the high speed information recording is obtained by selecting the voltage impressed to the information recording medium to be a voltage over an avalanche breakdown voltage of the depletion layer of the semiconductor layer.

Title: Pad printing method
Inventor: HIDA TSUNESHI
IPC: B41M1/40
Filed: 1983-11-25
Abstract: PURPOSE:To enable inexpensive and easy numbering by pad printing, by a method wherein a separately prepared intaglio printing plate is pressed against a solid coated part of a pad, and an ink is removed from the surface of the pad, leaving the ink in the form of a desired character. CONSTITUTION:The pad 2 brings an ink from a printing plate. An image part which is frequently changed is solid coated with the ink, and the pad 2 is momentarily stopped before printing on a printing material in order to press an intaglio printing plate 6 against the part. The plate 6 is pressed against the pad 2 by operating a character-replacing device so that the plate 6 coincides with the solid part on the surface of the pad 2. When the plate 6 is separated from the pad 2, the plate 6 carries away the ink from the part at which it has made contact with the pad 2, and the ink in the form of the desired character is left on the surface of the pad 2. The plate 6 with the ink adhered thereto is deprived of the ink by an ink remover equipped with an adhesive tape or the like, and is again used in the next cycle.
