Title: Rotation detector
Inventor: TAKAGI AKIRA
IPC: G01P3/44
Filed: 1988-01-26
Abstract: PURPOSE:To perform rotation detection by holding a 2nd member which produces lines of magnetic force in a stationary state above a 1st member made of a superconducting material by utilizing complete diamagnetic operation. CONSTITUTION:Liquefied nitrogen circulates in a cooling mechanism 5 and the inside of a case 3 is held at liquefied nitrogen temperature. At this time, a superconductive substrate is superconductive and a permanent magnet 2 floats above the superconducting substrate 1. When the device rotates in this state, the case 3 and superconductive substrate 1 rotate, but the magnet 2 is stationary in an absolute space, so it does not rotate. The magnet 2, however, rotates relatively to 1st, 2nd, and 3rd detectors 6, 7, and 8 fixed to the case 3 and its rotation state is detected by the detectors 6, 7, and 8.

Title: Picture data compression system
Inventor: MAEDA MITSURU
IPC: H04N1/41
Filed: 1987-01-28
Abstract: PURPOSE:To efficiently compress data by compressing no bit of color information of a monochrome picture even in picture data in which color picture data and monochrome picture data are mixed. CONSTITUTION:When the output of a mode switch is '1', namely, when the block information of a color picture is inputted, a selector 11 outputs input color picture data to a ROM 12. The ROM 12 inputs the block information of the inputted color picture data as the address of a memory and outputs a compressed result as an output. When the output of the mode switch is '0', namely, when the block information of a black and white picture is inputted, the selector 11 outputs input picture data to a ROM 13. The ROM 13 inputs the block information of the inputted black and white picture as the address of the memory and outputs the compressed result. Accordingly, only the brightness of color information is inputted to the ROM 13 and the color information is deleted and compressed.

Title: Signal voltage detecting circuit
Inventor: SHIBATA SHINTARO
IPC: G11C11/56
Filed: 1985-01-30
Abstract: PURPOSE:To shorten the working time by reflecting the potential difference between the 1st and 2nd nodes to the potential difference to be detected and charging or discharging the 1st and 2nd capacity charges via the 2nd MOS transistor. CONSTITUTION:The electric charge stored in the capacity of a lower potential level between the capacity C1 produced between an identification output node N1 and the earth and the capacity C2 produced between an identification output node N2 and the earth is discharged positively via MOS transistors (TR)Q1 and Q3 or Q2 and Q3 respectively. Thus the potential difference between both nodes N1 and N2 is increased. Here said discharge of the electric charge is carried out while both MOSTRs Q8 and Q9 are kept off. Therefore the electric charges stored in both capacities C1 and C2 formed between the nodes N1 and N2 and the earth respectively are never discharged through the TRs Q8 or Q9. This can decrease the working time during which the potential difference between both nodes N1 and N2 is increased and delivered as an identification output signal.

Title: Detecting method for generation of failure in transmission line, transmission method for information on generation of failure and locating system for failure section
Inventor: FUJIKURA KENICHI
IPC: H02J13/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which the generation of a failure can be detected even when a ground-wire current is not increased in the failure by a method wherein the deviation value between a present instantaneous value and an instantaneous value at the immediately preceding cycle of an AC cycle is found, instantaneous values are totaled retrospectively and a moment in which their totaled value exceeds a threshold value is detected as a moment in which the failure is generated. SOLUTION: An instantaneous value which is converted by an A/D converter 31 is converted into a light signal by an E/O conversion part 32 so as to be converted into an electric signal by an O/E conversion part 44. The instantaneous value is stored in a first memory 46. A stored instantaneous value which is at an immediately preceding cycle from a present cycle is fetched, and the deviation value between the present instantaneous value and the instantaneous value at the immediately preceding cycle is stored temporarily in a second memory 47. Values which are stored in the second memory 47 are totaled so as to retrospect prescribed sampled values from the present instantaneous value. When a failure is generated, a difference is generated by the present instantaneous value and the instantaneous value at the immediately preceding cycle.  The sum of the absolute values of differences becomes larger than a prescribed threshold value. Even when a system is a complicated line and a ground-wire current is not changed largely in a failure, the deviation of a waveform is evaluated, and the generation of the failure can be detected.
