Title: Information recording medium
Inventor: TAKEDA KATSUYUKI
IPC: G11B11/105
Filed: 1986-08-07
Abstract: PURPOSE:To obtain optimum recording power in respective parts and to decrease jitter and bit error rates while recording power is maintained constant by decreasing the thickness of an information recording layer continuously radially from the center toward the outer peripheral side of rotation. CONSTITUTION:The optimum recording power depends on the line speed of a disk during rotation. The optimum recording power is not attained in the inner peripheral part where the line speed is low and the outer peripheral part where the line speed is high in relation to the optimum recording power set in a certain radial direction; for example, the central part in a recording region, if the thickness of the magneto-optical recording layer is assumed to be uniform as with the conventional recording medium. Such fact evidences that the writing with the constant recording power is possible simply by decreasing the thickness of the magneto-optical recording layer continuously from the inside toward the outer peripheral part. Namely, the thickness of the magneto-optical recording layer is continuously decreased radially from the inside toward the outer peripheral part. The optimum recording power is thereby obtd. in the respective parts and the jitter and bit error rates are considerably decreased.

IPC: G01B7/00
Filed: 1981-11-19
Abstract: PURPOSE:To measure and monitor the burnout amount of the refractory of a molten metal container easily with high precision by embedding and incuctor in the refractory in its thickness direction, and measuring its self-inductance. CONSTITUTION:In a furnace-bottom refractory 2 lined at the inside of the furnace-bottom iron shell 1 of a converter, an insulating pipe 3 made of ceramics, etc., is embedded in the thickness direction of the refractory, and a solenoid coil 4 is arranged therein and fixed by a packing material 5. A wire electrode 7, on the other hand, is embedded near the coil 4. Both tips of coil 4 and electrode are brought into contact with molten metal 6 and the other-side ends are connected to a self-inductance measuring instrument, thus forming an electric circuit which uses the molten metal as part of the circuit. When the refractory near the embedding position of the coil is burnt out, the coil 4 decreases in length as a result, thereby decreasing the self-inductance.

Filed: 1986-08-11
Abstract: PURPOSE:To read a stable signal by forming the width of a bit, in which the bit length corresponding to an information signal is shorter than the diameter of a laser spot for reproduction, wider than the width of the bit longer than the diameter of the laser spot. CONSTITUTION:A bit width W2 of a bit 3 having a bit length shorter than a diameter (d) of a laser spot 1 for reproduction is formed larger than a bit width W1 of a bit 2 having a bit length longer than the diameter (d) of the laser spot 1 for the reproduction. In this case, when adjustment is executed so that the area of the bit 3 having the bit length shorter than the diameter (d) of the spot 1 can be equal to the area of the bit 2 having the bit length longer than the diameter (d) of the spot 1, the level of a reproducing output signal comes to be always constant regardless of the length of the bit length and the stable signal can be read. Since a short bit can be mixed and formed, the recording quantity can be improved.

IPC: H01L21/8229
Filed: 1980-12-29
Abstract: PURPOSE:To increase a series resistance to a clamp purpose diode by forming an N<+> type buried layer through a division in a memory cell having a high resistance and which is activated by a small current. CONSTITUTION:An N<+> type buried layer 13 provided in an N type epitaxial layer 2 is divided into two pieces, the region of the epitaxial layer 2 is extended through the current path from SBD (SChottky barrier diode) 2 to a transitor Q2 between the N<+> type buried layers 13 divided and a resistor R4 is formed between them. Therefore, a series resistance to the collector of the transistor Q2 is increased. Accordingly, if a noise comes, because the collector potential of the transistor Q2 is not more than the collector potential of a transistor Q1 and a reading level, a logic condition would not be inversed and therefore, any disturbance is not caused.
