Title: Magneto-optical recording medium
Inventor: ARAYA KATSUHISA
IPC: G11B7/24076
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To accommodate a higher numerical aperture, to accurately conduct the tracking control while reproducing information by irradiating light beams from the opposite side of a substrate and to secure good reproduced signals by making the region, which is projected to the light irradiated side and corresponding to the region of the inter-guiding groove among the magnetooptical recording film, as an information region. SOLUTION: A magneto-optical recording film 6 and a transparent protective film 8 are successively formed on a substrate 1 on which concentric circular with respect to one of main surface 1a of the magento-optical recording medium or spiral guiding groove 2 is formed. Light beams are irradiated form the film 8 side to reproduce information signals. By making the film 8 thinner, a high numerical aperture is sufficiently accommodated. Moreover, a tracking control is accurately conducted using the groove 2. In a magneto-optical recording medium, good reproduced signals are secured by making the region, which is projected to the light irradiated side and corresponding to the region of an inter-guiding groove section 3 among the film 6, as the information recording region.  Note that noise is further reduced by making the step shape of the boundary portion of the groove 2 to the shape which is deformed and projected to the substrate side.

Abstract: PURPOSE:To prevent the malfunction due to dV/dt surely, by providing a transient current detecting circuit using an active element and by making input and output terminals of this circuit bidirectional in dielectric strength and operation. CONSTITUTION:If a positive or negative rapid potential fluctuation occurs in a main terminal 6a or 6b when a thyristor 9 is not operated, the transient current is flowed through a route of the main terminal 6a and a transistor 12 and drives a transistor 10 and reaches the main terminal 6b. At this time, the transient current is amplified by a transistor 12 of a transient current detecting circuit and becomes a larger current. As the result, the voltage between the gate and the cathode of the thyristor 9 is clamped at the voltage between the collector and the emitter of the transistor 10, thereby preventing the malfunction of the thyristor.

IPC: G06T1/00
Filed: 1995-05-26
Abstract: PURPOSE: To correctly detect a nodular shadow by converting a tomographic image including an area extracted as an abnormal shadow candidate by plural threshold processing into a cross section and judging whether the extracted area is an abnormal shadow or not. CONSTITUTION: A threshold processor 12 has plural thresholds, executes the threshold processing of a tomographic image based upon the thresholds and extracts an area to be an abnormal shadow candidate. A cross section converter 15 converts the tomographic image including the extracted area into a cross section and a nodular shadow judging device 14 judges whether the area extracted from the image converted into the cross section is an abnormal shadow or not. The device 14 executes its decision based upon reference data for judging a nodular shadow which are stored in a nodular shadow judgement storing part 18 and reference data for the degree of roundness which are stored in a roundness degree storing part 19.  In this method, the judgement of an abnormal shadow can be executed by a low threshold, and even when a nodular shadow is close to another shadow, the nodular shadow can be correctly detected.

Abstract: PURPOSE: To provide a pressure regulating valve device applicable to water pumping from either shallow or deep wells comprising forming a convex either on a valve proper or on a valve seat and a concave on the valve seat or valve proper on which no convex has been formed, and varying the position of the valve proper mounted on the valve seat with respect to the convex and concave.  
     CONSTITUTION: In the proposed pressure regulating valve device 8, a valve proper 24 is mounted on a valve seat 18 so that a convex 34 formed on the valve proper does not go into a concave 22 formed on the valve seat, and a clearance as wide as the height of the convex 34 is formed between the valve proper and the valve seat. The device, accordingly, is made suitable for application to pumping of water from shallow wells. On the other hand, the valve proper 24 may be mounted on the valve seat 18 with a design such that the convex 34 and the concave 22 come into engagement with each other, and the surfaces of the valve proper 24 and the valve seat 18 come closely into contact, thus the pressure inside a casing 4 is kept closed after pumping is started and before the valve 24 is lifted by small pressure. This arrangement of the valve proper and the valve seat with respect to the convex and the concave is applicable to pumping of water from deep wells. According to the device, the pumping mechanism can be worked without drop of pressure inside the casing 4 at the time of started pumping operation and consequent stoppage of water drawing.

Abstract: PURPOSE:To encode a run length of high data compressibility by representing a run length code from the last change point to the completion of an image data by a line end code. CONSTITUTION:The input data IDATA is successively converted into a run length code. During a time from the last change point of the input data until a line enable signal LEN goes to low, an encoding is not performed. Instead thereof, one code of WEOL (white line end) or BEOL (black line end) is outputted. A mode control circuit 14, when the change point is not detected by a change point detecting circuit 12 from a start to a completion of the input data IDATA, namely, during a period of HIGH of the line enable LEN, outputs the WEOL or BEOL when the line enable signal LEN goes to low. Accordingly, the run length code indicating the image of one line is shortened.
