IPC: G05D1/02
Filed: 1987-09-04
Abstract: PURPOSE:To guide the vehicle smoothly to a constant target position by operating and determining the radius and angle of vehicle rotation to a target position. CONSTITUTION:Angles phi and theta of the front center C of the vehicle to reference points S1 and S2 provided across a target position 0 are detected and distances to the reference points S1 and S2 are calculated. Then the angle xsi where the longitudinal axis of the vehicle meets an x axis is calculated from the angles phiand theta and distances l and (r). Then the distance Qx between the center C2 of the axle of the vehicle and a y axis which passes the target position 0 and crosses the x axis at right angles is calculated from the angles phi, theta and thetaand distances l and (r). Then a 1st vehicle rotational radius R1 and a 1st vehicle rotational angle phi1 are set and the vehicle is turned according to them. Then a 2nd vehicle rotational radius R2 and a 2nd vehicle rotational angle phi2 are calculated from the rotational radius Ra, rotational angle phi1, angle xsi, and distance Qx and the vehicle is turned according to them. Then the vehicle is put in a straight moving state to reach the target position.

Title: Differential relay method
Inventor: MAEDA TAKAFUMI
IPC: H02H7/045
Filed: 1992-07-30
Abstract: PURPOSE:To make it possible to identify an exciting rush current and an accident current even though a large transient vibration component is present in a ground fault current by judging the percentage of harmonic components of difference current and an integrated value of terminal voltage. CONSTITUTION:A difference current of a transformer as a protection target is determined by a main judging element 1, for instance, a judgement is made by a ratio differential method. The difference current determined by the main judging element 1 is received by a harmonic element 2, and an output is sent when the percentage of harmonic components of this difference current is lower than a predetermined value. Whether the absolute value of an integrated value of a transformer terminal voltage is less than a judged constant is judged by an integrating element 3. By the OR logic 7, the logic sum of an output from a harmonic element 2 and an output from integrating element 3 is determined. If it has an output, the output of the main judging element 1 is permitted by an AND logic 8, and a final output is created. By this configuration, a ground fault is identified as the state of exciting rush including the case where the transient vibration component of the difference current is large, and a final value can be correctly obtained from the output of the judging elements.

Filed: 1988-09-08
Abstract: PURPOSE:To protect an aerial transmission line economically and reliably by supporting an aerial power line by means of steel suspension towers and steel tension towers, then arranging an arrester element only on the steel tension tower and lowering the voltage withstandability of the tension insulator string thereof. CONSTITUTION:An aerial power line 3 is supported by steel tension towers 10 having tension insulator strings 4 and steel suspension towers 11 having suspension insulator strings 9, where arcing horns 5 are arranged in parallel with respective insulator strings. An arrester element 6 has one end connected with the aerial power line 3 between a pair of tension insulator strings 4 on the steel tension tower 10. Although no arrester element 6 is arranged on the steel suspension tower 11, voltage withstandability of the suspension insulator string 9 is set higher than that of the tension insulator string 4. Lightning surge does not flash over the arcing horn 5 on the steel tension tower 10 because of the arrester element 6 nor the lightning surge flash over the arcing horn 5 on the steel suspension tower 11 because of the enhanced voltage withstandability of the suspension insulator string 9. By such arrangement, the number of the arrester element 6 is reduced and the economy is improved.

Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of an image recognizing function by providing a device with a means making supplied image data and image data which should be given to an image forming means interchangeable. SOLUTION: By an image recognition circuit 21, a specified image such as a paper money being an object to be recognized is recognized from the inputted image data. when the specified image is recognized, the inputted image data is cut and prevented from being outputted to a printer engine 3. Since the data inputted to an image recognition device 2 and the data outputted from the recognition device 2 are not interchangeable, a converter 22 for making the data compatible is arranged on the inside of the recognition device 2. The digital image data from an image processing circuit 1 is inputted to the recognition circuit 21 and also inputted to the converter 22. When the specified image such as the paper money is recognized by the recognition circuit 21, a recognized result switch circuit 23 is controlled and the output of the print of the specified image is obstructed.  Thus, even when the specified image is intentionally directly outputted to the printer engine 3 without being inputted to the recognition device 2, this image processor is not normally actuated.
