Title: Detecting system of faulty section
Inventor: KAWAKAMI HIROSHI
IPC: G01R31/08
Filed: 1988-04-30
Abstract: PURPOSE:To discriminate the presence or absence of a fault in a transmission line section by a method wherein a time required from the time when a zero-phase current exceeds a prescribed value on the occasion of the fault to the time when a zero cross point is measured at the opposite ends of the transmission line section, and the times measured at the opposite ends are compared with each other. CONSTITUTION:In each of detecting devices 9 at the opposite ends A and B, the value of a zero-phase current signal obtained from a zero-phasing circuit 11 exceeds a set value of a comparator circuit 12. The zero-cross current signal is zero-crossed from the negative to the positive at a time tA in the device 9 at the end A and at a time tB in the device 9 at the end B. At the times tA and tB, counter circuits 14 at the opposite ends A and B complete counting of count pulses respectively. The count value of the pulses represents a time length from the point of occurrence of a fault to the point whereat the zero-phase current is zero- crossed from the negative to the positive. Displayed values in display units 16 are compared with each other, and the fault is assumed as the one inside a section of an underground transmission line 2 when the displayed values are different by about 180 degrees from each other, while it is assumed as the fault outside the section of the transmission line 2 when the displayed values are the same substantially. Accordingly, the presence or absence of the fault inside the section of the transmission line is discriminated.

Title: Encryption deciphering system
Inventor: SHONO KATSUFUSA
IPC: H04L9/26
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain a system which allows deciphering only on the signal receiver by utilizing time series varying in resolution of quantization. SOLUTION: A deciphering code is formed by discovering a cipher code y(t-τ) by retrieval of the internal state y(t) of the time series of chaos and discovering y(t-τ+τ) with the transmitted cipher code y(t-τ) as an initial value. A signal transmitter forms the cipher code in excess of the discrete time when the error does not arise on the time series of the chaos having the low resolution provided from the signal receiver side. The signal receiver side is able to publicize and impart the time series of the same chaos to the many signal transmitters. Safety is thereby sufficiently assured. The deciphering of the once encryupted cipher code is not possible in the time series of the chaos existing on the signal transmission side. The time series of the chaos having the higher resolution is prepd. and the deciphering is easy on the signal reception side.

Title: Tension controller
Inventor: KOMODA NORIKIYO
IPC: G11B15/43
Filed: 1989-04-27
Abstract: PURPOSE:To give the stable prescribed tension even in the case a tape running state is stable and in the case it is in a transient state by detecting the speed-of- revolution information of a reel, and also, discriminating whether a speed of the tape is in a stable state or not. CONSTITUTION:Since a speed of a tape 1 is constant, periodic information outputted from a periodic information converting means 7 is information being proportional to a radius of a reel 2. From a multiplying circuit 9, torque information being proportional to the radius of the reel 2 is outputted by multiplying the periodic information by a constant. In this case, since a tape speed is in a stationary state, from a result of output of a comparing means 8, an output (torque information) of the multiplying circuit 9 is latched by a holding means 10, and outputted to a driving circuit 11. A reel driving device 4 is driven by the driving circuit 11, and an output of the holding means 10 is converted to torque. Accordingly, tension applied to the tape 1 becomes constant irrespective of the radius of the reel 2. Also, in the case the tape speed is in a transient state, by a result of output of the comparing means 8, the output of the multiplying circuit 9 latched at the time of a stable state is held by the holding means 10.
