Title: Method for judging ground liquefaction
Inventor: NAKAMURA YUTAKA
IPC: G01M99/00
Filed: 1993-06-21
Abstract: PURPOSE:To easily judge the occurrence of ground liquefaction for entire ground. CONSTITUTION:The microtremors of ground are measured as to horizontal two-directional components that orthogonally intersect each other and a vertical component, and the ratios of the Fourier spectrum of one component to that of another are calculated. The characteristic of the spectrum ratio shows the vibration characteristic of the ground; in the case of hard ground it becomes almost one over the entire frequency bands; in the case of ground with contract in hardness a certain frequency band is predominant. In the case of such ground that could undergo liquefaction, the spectrum ratio is less than one in frequency bands higher than a definite dominant frequency, or does not show any define dominant frequency and in that case it is far below one over a wide frequency band. Thus the occurrence of ground can be detected according to whether or not the spectrum ratio calculated is less than one over a wide band. Also, the degree of liquefaction can be determined according to the extent of the range wherein the spectrum ratio is less than one.

Title: Web interlacing method by high pressure water jet and jet head for interlacing
Inventor: TATSUMI HAJIME
IPC: D04H1/492
Filed: 1992-07-01
Abstract: PURPOSE:To exclude attenuation of interlacing action due to water drops except a jet water stream by actively sucking and excluding water drops lying around the place where interlaces are carried out by the jet water stream. CONSTITUTION:A jet stream J is jetted from a nozzle 3a onto a web W which is put on a net conveyer N and is moving under a jet head 1. The jet stream J directly hits the web W, the net conveyer or a suction box under the conveyer and splashes back to three-dimensionally interlace fibers in the web W. At this moment, misty water drops M arise around a jet mouth 6a an water drops S around the web W where the jet stream J is hitting to attenuate force of the jet stream J, making it difficult to interlace fibers. So, sucking paths 9 are made in a nozzle case 2 and a cover plate 6 in a given pitch at fore and rear part of the nozzle case 2 and at the opposite side of the jet mouth 6a., thus actively excluding water drops M, S and air to the outside by driving a ventilation blower 12.
