Title: Magneto-optical recording system
Inventor: ISHII OSAMU
IPC: G11B11/105
Filed: 1987-06-12
Abstract: PURPOSE:To eliminate a bias magnetic field by applying a processing magnetizing the entire medium in a direction in advance. CONSTITUTION:A magnetic thin film of two-layer structure composed of a recording layer 3 and an auxiliary layer 2 is used as a magneto-optical recording medium. The Curie temperature of each layer is lower in the order of the auxiliary layer 2 and the recording layer 3, the auxiliary layer and the recording layer are made of perpendicular magnetization film and the perpendicular magnetic anisotropy is smaller in the order of the recording layer 3 and the auxiliary layer 2. The medium is magnetized uniformly in perpendicular direction to the film face in advance (the processing is called as the initial magnetization and the magnetized direction is referred to as positive direction as the convenience of explanation). Then when a light beam 5 irradiates a recording area to heat the corresponding part and to record the information, the light beam intensity is changed into two levels of strong/weak levels in response to the information signal. Thus, no bias magnetic field is required, the device is simplified, and the miniaturization of the device and the reduction of the weight are attained.

Title: Electrolytic machining device
Inventor: ARAI SHINJI
IPC: B23H3/02
Filed: 1982-08-23
Abstract: PURPOSE:To enable an optimum process of electrolytic machining for shortening a working time to be applied to an electrolytic machining device while working accuracy is maintained in a predetermined value. CONSTITUTION:In case of diesinking, a gap to a vertical surface has a (ga) value at maximum but has a (go) value at minimum which is equal to a gap to a bottom surface when an aqueous solution of oxygen containing-acid is used. Accordingly, with the use of an electrode which is less by the (ga) value, the error of the electrolytic machining becomes (ga-go). This relation is also established to an inclined surface. Therefore, the electrolytic machining with high accuracy is ensured by carrying out the machining with the (ga) value small as possible and the small value of (ga-go).

Title: Medium detecting circuit
Inventor: NAKAYASU TAKAFUMI
IPC: G01V8/12
Filed: 1990-06-06
Abstract: PURPOSE:To mount a sensor at the position where external light is present and to detect whether or not a medium is present by emitting the light output of a light emitting element which varies periodically and comparing the received signal from the medium with the irradiation light. CONSTITUTION:A +5V power source which varies periodically is connected to supply a PE(from presence/absence detection) driving signal to an LED 1 from an oscillation circuit 5 and the light which blacks periodically is outputted. The light is reflected by or transmitted by paper as the medium to be detected and inputted to a light receiving element 2. The element 2 receives no light when there is neither paper nor disturbance to output a low-level voltage, receives the light at all times when there is no paper and a disturbance is present to output a high-level voltage, and receives the blinking light when there is paper to generate the high- and low-level outputs alternately. Those PE received signals are processed by a CPU 6 to decide whether or not there is the paper. A PE sensor 14 of such configuration is not restrained by external light, so it is installed, for example, on an entrance side about a pinch roller 13 and can detect the insertion of paper and the sensor is usable for triggering form suction and also contributes to the improvement of operability and the diversification of a medium route.
