Title: Pipe body pressure resisting closing mechanism
Inventor: KITAWAKI MICHIO
IPC: F16L55/12
Filed: 1988-05-06
Abstract: PURPOSE:To ensure a sufficiently stable closing seal by providing a stopper mounting plate to be arranged between a pressing plate and a nut member and mounting an expansion connecting material to the stopper mounting plate in its peripheral part. CONSTITUTION:An interposing receiving member 6 and two or more stopper mounting plates 7 are provided to be arranged between a pressing plate 3 and a nut member 5, and an expansion connecting material 8 is mounted to a peripheral part of the stopper mounting plate 7. In this way, when the nut member 5 is tightened, a ring-shaped seal material 4 is flexed and swollen in the peripheral direction, but each stopper mounting plate 7 is spread in an opening umbrella shape against elasticity of the expansion connecting material 8, because its play end comes into press contact with a pipe body 10 in its internal surface, a sufficiently stable seal can be ensured even when fluid in a pipe generates a considerably high pressure.

Title: Overhead power transmission line
Inventor: OKADA KENJI
IPC: H01B5/10
Filed: 1987-05-03
Abstract: PURPOSE:To prevent galloping by bringing the wire twist cycle of an overhead power transmission line, to which a torsion preventive appliance is mounted, to one half or less of the cycle of vertical vibrations. CONSTITUTION:When an overhead power transmission line 1 receives wind, the vibrations of low frequency and large amplitude, galloping vibrations, are generated, and the cycle of twist of the power transmission line and the cycle of vertical vibrations coincide with each other at all times in this case. Consequently, the cycle of twist and the vertical cycle conform, and lift is received from wind, thus largely developing galloping vibrations. As a result, the wire twist cycle and the vertical cycle are made to differ, and a torsion preventive appliance 4 is constituted so that the twist cycle is brought particularly to one half or less of the vertical cycle, thus completely preventing the generation of galloping. Since the loop number of vibrations generated in the overhead power transmission line 1 between steel towers 2, 3 is made the same as the number of the torsion preventive appliances 4 set up to the overhead power transmission line 1 in most cases, the loop number of vibrations between the span can be determined by the number of the torsion preventive appliances fitted to the line 1.

Abstract: PURPOSE:To accurately guide a puncture needle to an objective position, by providing a means for successively increasing the driving frequency of a vibrator from the end part of an array toward a central part and a means for setting an ultrasonic wave converging point toward the deep part of a body to be examined corresponding to the driving frequency. CONSTITUTION:The data determining the selection of vibrators as one for biopsy is preliminarily stored in a ROM 6 for selecting the vibrators and the data of a delay time setting the converging point of an ultrasonic wave is preliminarily stored in a ROM 12 for setting a delay time. A controller 20 outputs a selection signal SC and each ultrasonic scanning line indicating signal LN constituting an ultrasonic tomographic image and the corresponding data are read from the ROMs 6, 12 to change over the connection of a multiplexer 4 and the delay time of a delay circuit 10 is set. Pulse voltage is applied to the vibrator selected by the multiplexer 4 from a transmitting/receiving circuit 8 and an ultrasonic wave is emitted into a body to be examined. By this method, since the ultrasonic wave is converged along the penetrating direction of a puncture needle, the resolving power of the ultrasonic tomographic image at the end part of an array is enhanced and the puncture needle can be accurately guided to an objective position.

IPC: H03H9/145
Filed: 1980-08-08
Abstract: PURPOSE:To enlarge the variation width of a delay time, by providing receiving electrodes at different intervals on the right and left of a transmitting electrode, and providing signals which are out of phase, to right and left electrodes in the transmitting electrode. CONSTITUTION:When phase of a signal which is applied to the first electrode 2 of a transducer 21 in the center through a phase shifter 24 is led by 90 deg. than the second electrode 3, a surface wave is generated from the transducer 21 to a transducer 23. Accordingly, a delay time in this case is proportional to a distance between the transducer 21 and the transducer 23. When a signal lagged by 90 deg. is  applied, the delay time is proportional to a distance between the transducer 21 and a transducer 22. When a phase difference is 90 deg.--90 deg., outputs of the transducer 22 and the transducer 23 are synthesized, and an intermediate value is taken as a delay time, too.
