Title: Method for identifying accident section of power cable
Inventor: YOSHIDA SHOTARO
IPC: G01R31/08
Filed: 1987-06-19
Abstract: PURPOSE:To detect an accident section by a reduced number of current detectors, by detecting current values in block with respect to three phases at every cross bond sections and comparing the magnitudes or polarities of the current values at every sections. CONSTITUTION:When it is supposed that an earth accident is generated at the accident point 60 of a cross bond section 41, the CT 50 of the accident circuit detects the sum of a conductor current and a sheath current. The current value detected by the CT 50 is almost zero in both of the accident circuit and sound circuit of the cross-bond section 41 having the accident point 60 (i). The current value becomes larger as separated from the accident point 60 in the accident circuit (ii) but becomes smaller as separated from the accident point 60 in the sound circuit (iii). By utilizing the above-mentioned phenomenon, the accident section can be known. In the case of two parallel circuits like this case, the circuit generating an accident is immediately identified from the value of the CT mounted to a substation.

Abstract: PURPOSE:To completely process paper or the like through one procedure by releasing the pressing against a roller when the paper or the like is pulled in a conveyance direction. CONSTITUTION:A background roller 2 pressed against a reader 1 is engaged with a drive gear 3 through a gear 2a. When the paper or the like 5a is pulled in the direction of an arrow 9a, the background roller 2 moves upward together with the pulling, and is stored in a position 2'. The background roller 2 rotates with the rotational center of the driving gear 3 as a center. However the design of the roller 2 is not limited to that. That is, the background roller 2 may be provided with an assembling mechanism so that the force applied when the paper or the like 5a is pulled produces the component of force in the direction of separating the background roller 2 from the reader 1. When a teared or jammed paper is handled, it is pulled out of the outlet of the reader. Therefore one procedure is sufficient for complete processing.

An input electrode 6 and an output electrode 7 are provided close to each other on the TRD4, and an input terminal 8, an output terminal 9 and a common electrode 10 are led out of the electrodes 6 and 7. Thus an electro-mechanical converter T is obtained. An absorbing gate 11 is coated on both surfaces of the medium 1 to prevent the ultrasonic wave from leaking out to other ultrasonic wave routes as an undesired wave. When an electric signal is applied between the terminals 8 and 10, the ultrasonic wave sent from the surface 2 is reflected on end surfaces 12a-12c at a 45 deg. angle. This reflected wave reaches a cut surface 3 and reflected to the opposite direction to return to the surface 2. Then the output electric signal is delivered to the area between the terminals 9 and 10 by the vibrations of the TRD4.
