Title: Method and equipment for extracting edge and line
Inventor: ROBAATO EICHI MEIAA
IPC: G06T7/60
Filed: 1990-03-27
Abstract: PURPOSE: To correctly discriminate between high and low contrast picture characteristics by detecting the intensity of picture data along a scanning line and confirming edge points as points along the scanning line between a pair of curvature poles between which the intensity difference exceeds a prescribed threshold. CONSTITUTION: The inclination of a line connecting an arbitrary point 14 on an intensity curve 10 and a point 16 is determined, and in the same manner, that of a line connecting a next point 18 and the point 14 is determined. Next, a slip difference between angular inclinations is obtained for the purpose of obtaining an inclination curvature at each point along the scanning line, and for example, the inclination curvature at the first point 14 is equal to the result obtained by subtracting the angular inclination at the first point 14 from that at the second point 18. Next, a curvature pole is positioned, and the curvature pole is indicated by a circular point 20, and inclinations between the curvature pole 20 and the preceding point and between that and the succeeding point are relatively large. The face side of the edge boundary in picture data is characterized by the quick change of the intensity. Thus, high and low contrasts are correctly discriminated.

Title: Magnetic head
Inventor: YONEDA HIROSHI
IPC: G11B5/127
Filed: 1981-05-26
Abstract: PURPOSE:To increase an erasure rate by dividing a center core in the moving direction of a magnetic recording medium, and then providing a nonmagnetic layer between the divided center core parts. CONSTITUTION:A center core is separated into two center core parts 2a and 2b in the moving direction of a magnetic recording medium, and a nonmagnetic layer 6 is interposed between the both. Because of the nonmagnetic layer 6, the magnetic field established in a front gap 3b by medium magnetism before erasure is reduced greatly. Therefore, recording is suppressed and a ratio of erasure is increased. In this case, the nonmagnetic layer 6 suppresses said magnetic field crossing the layer, but never weakens an original magnetic field for erasure because the magnetic field does not cross the layer 6.

Title: Planar inductance element
Inventor: YOKOGAWA TETSUYA
IPC: H01F30/08
Filed: 1990-03-29
Abstract: PURPOSE:To contrive flattening of magnetic flux density on the center part and the outer circumferential part of a conductor by a method wherein a plane-surfaced coil, with which a conductor is spirally wound, is pinched by a pair of magnetic bodies through the intermediary of an insulator, and the above-mentioned plane-surfaced coil is wound in such a manner that it becomes coarser as approaching closer to the spiral center part. CONSTITUTION:A plane-surfaced inductance element 11 is constituted in such a manner that both front and back sides of a plane-surfaced coil 12 are pinched by a pair of magnetic materials 14a and 14b through the intermediary of a pair of electrically insulated members 13a and 13b. The plane-surfaced coil 12 is formed by spirally winding a conductor 12a on a plane surface in such a manner that the winding pitch P0 of its center part O becomes larger than the winding pitch PG of the outer circumferential part G, namely, the wire turns become smaller as the center part O is approached. Accordingly, the peak of density of magnetic flux distributed on the center part of the pair of magnetic bodies 14a and 14b corresponding to the center part of the spiral winding is suppressed. On the other hand, the density of magnetic flux on the outer circumference G of the spiral winding is enhanced, and the magnetic flux density of the flat-surfaced inductance element 11 can be made almost flat at the center part and the outer circumferential part.

Abstract: PURPOSE:To increase the capacity of a capacitor even if impressed voltage is small and to stably drive a sense amplifier by providing the semiconductor memory with a capacitor constituted of a MOS transistor (TR) itself. CONSTITUTION:When the sense amplifier 3 is not driven, charging switches 71, 72 are turned on and driving switches 81, 82 and restoring switches 91, 92 are turned off. Under this condition, the capacitor 3 is charged. Thereby, a word line is raised, data appear on bit lines 101, 102, the switches 81, 82 are turned on, and then the switches 71, 72, 91, 92 are turned off. Thus, the sense amplifier 3 is driven.

Abstract: PURPOSE:To allow a center station to confirm the result of transfer efficiently by converting a telephone number of its own station in a data storage section into a sender terminal identification signal at the detection of a nonstandard function signal from a receiver side or at the detection of its own company code in a nonstandard function signal. CONSTITUTION:When a nonstandard function signal NSF sent from a receiver side or it is detected that a maker code included in the nonstandard function signal NSF is its own company, a sender terminal identification signal TSI converted into an accurate telephone number is sent to allow the receiver side to recognize the sender telephone number itself. Thus, since transfer stations 2, 3 recognize it that the content itself of the TSI signal sent from a center station 1 is a telephone number of the center station 1, the result of transfer to a group of terminal stations 2a-2c and to a group of terminal stations 3a-3c is returned from the transfer stations 2, 3 to the center station 1 easily and a call from the transfer stations 2, 3 to the center station 1 is attained. Thus, the confirmation of the result of transfer at the center station 1 is implemented efficiently.

Abstract: PURPOSE:To switch automatically to the stereo system of a broadcasting signal by detecting a stereo discriminating signal, which is superimposed over the difference signal of each system, and utilizing it to control a system switching circuit. CONSTITUTION:A synchronized stereo signal is inputted to difference signal demodulation circuits 12-15 and a demodulation circuit 16 of the Harris system. If the circuit 12 is a corresponding circuit, the circuit 12 demodulates a difference signal. Since a stereo discriminating circuit 17 recognizes a stereo discriminating signal, and the signal make a switching circuit 22 to be in an energized state, the democulated difference signal is inputted to a matrix circuit 28. On the other hand, a sum signal demodulated by a sum signal demodulation circuit 11 is inputted to the circuit 28 via a sum signal switching circuit 27. For the stereo signal of the Harris system, the circuit 16 demodulates a sum and difference signals. In this case, the circuit 27 is switched to a terminal 27b with the stereo discriminating signal of a stereo discriminating circuit 21, and the sum and difference signals are supplied to the circuit 28 because a switching circuit 26 is in a state of continuity.

Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To make possible use of an existing ballasted track as it is, without removing it by filling highly liquid concrete mortar into voids in the existing ballasted track. SOLUTION: A shuttering 6 is installed at the side of an existing ballasted track 1 having a rail 5 laid on the top of a ballast 3 on a roadbed through a crosstie 4. After prescribed preparatory work, a concrete-filled ballast is constructed by penetrating a highly liquid concrete placement pipe 7 having a vibration mechanism into the ballast 3. The highly liquid concrete has liquidity enough to fill every corner of the shuttering without using a vibrator and material separation resistance enough to pass through among reinforcements without causing flow obstruction due to material separation while flowing. Thus construction is possible while the existing ballast is left placed, and it is also possible to start operating trains early.
