IPC: G11B7/2405
Filed: 1995-03-02
Abstract: PURPOSE: To obtain an optical disk capable of high density reproduction above the limitation of reproduction due to the wavelength of light from a light source and the lens NA. CONSTITUTION: This optical disk has a magneto-optical material layer 3 made of a rare earth element-transition metal ferromagnetic material on the transparent substrate 2 with pits 2A formed in accordance with information. At the time of reproduction, the magnetization directions of the magneto-optical material layer 3 are aligned in one direction and the layer 3 is irradiated with laser light for reproduction while applying an external magnetic field in a direction reverse to the one magnetization direction. A rear part in the irradiated spot attains to a high temp. and this high-temp. part is subjected to the inversion of magnetization by the external magnetic field.  Information is reproduced by detecting the change of the quantity of light reflected from the part subjected to the inversion of magnetization or a part not subjected to the inversion of magnetization in accordance with the pits 2A.

Abstract: PURPOSE:To decide the trouble by finding the rise rate of oil temperature for a given time after the start of the operation of the oil-immersed equipment which is operated and stopped repeatedly. CONSTITUTION:A reasoning engine 3 consists of a means 30 which finds the rise rate DELTAK of oil temperature for the given time after the start of the operation of the oil-immersed equipment 1, respective sensor outputs 31 which detect and store various sensor outputs of the equipment 1, and a reasoning part 32. Further, a knowledge base 4 is stored with the relation among correcting quantities for DELTAK corresponding to the outputs of sensors for detecting environmental conditions, the outputs of other sensors, and trouble states as knowledge. Then the reasoning part 32 reasons the contents of fault diagnosis according to the information from the sensors and the knowledge of the base 4. In this constitution, when the rise in oil temperature which is the given time T after the operation start is denoted as DELTAT, DELTAK is DELTAT/T. If fault occurs in the equipment 1 during this period, the DELTAK varies and becomes large in general. For the purpose, the DELTAK is monitored to decide the trouble even when the operation and stopping of the equipment 1 are repeated.

Filed: 1985-04-03
Abstract: PURPOSE:To prevent excessive electrical discharge, by providing a change-over means for changing a wiring section so that, when head lamps are turned on, the other lamps are connected in series to a power source, thereby the total consumption current is reduced during the time of turn-on of the head lamps at which the power source discharges its maximum current. CONSTITUTION:A switch 6 is alone closed to turn on clearance lamps 2A, 2B and tail lamps 2C, 2D. Then, a coil 7 in a relay device constituting a change- over means 5 will not be energized while switches 5B, 5D are closed, and therefore, the lamps 2A through 2D are connected in parallel to a battery 3. Meanwhile, a switch 8 is closed to turn on head lamps 1 while the switch 6 is left to be closed. Then the coil 7 is energized, simultaneously with the turn-on of the head lamps 1, and therefore the switches 5B, 5D are opened while switches 5A, 5C connect the lamps 2A-2D in series. As a result, the total consumption current is reduced upon turn-on of the head lamps 1, thereby it is possible to prevent excessive electrical discharge of the battery.
