Title: Surge location system for transmission line
Inventor: OOHIRA TAKESHI
IPC: G01R31/08
Filed: 1994-12-28
Abstract: PURPOSE: To locate a surge highly accurately even when the surge is taken in from a common bus by correcting the arriving time of surge with a reference level corresponding to a selected arriving level of surge. CONSTITUTION: A surge generated on a transmission line is received 12 on a bus 11 at an end mater station 10 or slave station 50 and when the output signal reaches a threshold value VTH, a VTH detection signal 14 is delivered and latched 16. When the output signal 12 reaches a level Vm1 -Vm3 determined while taking account of the number of lines connected with the bus 11, V1 -V3 level detecting sections 18, 22 and 26 deliver detection signals which are then latched 20, 24, 28. The counts 32 are latched 34, 36, 38 at the time of delivery of detection signals. A CPU reads outs the latched counts and when a modem 44 accepts the data received from the slave station 50, a common reference level is determined for the surge arriving at the terminals 60 on the master station side and the slave station side.  Two desired reference levels are then selected and used for correcting the arriving time of surge linearly. Finally, the surge is located based on the corrected time.

Inventor: IDA TAKASHI
IPC: G01N29/24
Filed: 1992-11-11
Abstract: PURPOSE:To ensure the observation of the reflected wave from the defect in a solid by avoiding the reflected wave from the surface of the solid generated when flaw detection is performed at a part directly beneath the surface of the solid with an ultrasonic wave probe. CONSTITUTION:An ultrasonic wave probe transmits ultrasonic waves to a material under test 2, which is placed in a medium, using water or another liquid 3 as the medium and performs the flaw detection in the material under test 2. An ultrasonic-wave transmitting/receiving surface 100 exhibits approximately line symmetry. The ultrasonic waves are concentrated in the vicinity of the axis of symmetry in the material under test 2 in this constitution. An ultrasonic- wave intercepting member 4 is arranged at the central part including the axis of symmetry of the ultrasonic-wave transmitting/receiving surface 100 in front of the ultrasonic-wave transmitting/receiving surface 100. Or the ultrasonic-wave transmitting/receiving surface 100 has a part 5 where the ultrasonic-wave transmitting/receiving surface is not provided, at the central part including the axis of symmetry. When this constitution is adopted, the central part of the ultrasonic-wave transmitting/receiving surface 100 does not detect the surface echo, and the detection of the defect echo is not impeded.

IPC: H04N1/32
Filed: 1989-12-19
Abstract: PURPOSE:To stop the processing to a picture not requiring picture processing by providing a processing class declaring means declaring a processing class commanded by a picture processing command means to a receiver side as a communication pre- procedure and a processing specifying means specifying the picture processing applied to a reception processing signal based on the processing class declared by the processing class declaring means. CONSTITUTION:In the absence of an input of information relating to a transmission picture from a picture information input section 11, a processing discrimination section 13 selects a proper picture signal processing method (simple binary or halftone) based on a processing signal from an original read section 1. When the storage of the signal is finished, a CPU 6 gives a command to call the communication opposite party to a transmission control section 5 and declares it to the communication opposite party as the transmission pre-procedure for the kind of the picture information, that is, the simple binarizing processing or the processing for making into halftone. A CPU 25 at the reception side analyzes the control information from the communication opposite party received by a reception control section 20 and discriminates whether the picture is the picture subject to simple binarizing processing or the picture subject to the processing for making into halftone based on the kind of the picture information declared as the pre-procedure.

Filed: 1988-12-27
Abstract: PURPOSE:To improve the resolution property, the brightness property, and the evenness of brightness by deforming the tips of columnar crystals of a phosphor layer to obtain the composition to fill up the clearances between the columnar crystals. CONSTITUTION:A phosphor layer 3 is a group of columnar crystals, and the columnar crystals have tips 7 and make clearances each other. In such a condition, the phosphor layer 3 is ground by a grinder from the center of the surface to the periphery along the curved surface of the input phosphor screen. As a result, pin holes on the surface of the layer 3 can be filled up. Consequently, since the substance composing the photoelectric screen formed on the layer 3 generates no diffusion or extinguish, the reduction and the deterioration with the passage of time of the initial sensitivity of the photoelectric screen can be prevented. Particularly, by regulating to increase the deformation amount of the input photoelectric screen more at the periphery than at the center, the evenness of the brightness can be improved.
