IPC: G01M3/28
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To monitor the leakage in a manner of distribution operation by a method wherein flow rate information of a first transport pipeline and second and third trans port pipelines branched therefrom are compared with each other to be discriminated and leakage judgment for multiple transport pipelines is executed by dividing into sections by each transport pipe. SOLUTION: A flow rate in a first transport pipe-line 10 is measured by an ultrasonic flow meter 11 and the measured first flow rate information is transmitted by means of a radio device 12. For example, three second transport pipelines 13 are branched from the pipeline 10 at a downstream side of the flow meter 11 and ultrasonic flow meters 14 are provided to the most upstream sides of the second transport pipelines 13, respectively.

IPC: G11B5/708
Filed: 1983-12-28
Abstract: PURPOSE:To reduce considerably glass bead powder and crushed matters to be mixed into a magnetic layer of a produced magnetic recording medium, by using wear-resisting glass beads, whose bead wear rate is a specific value, as a solid dispersion assistant. CONSTITUTION:Wear-resisting glass beads whose bead wear rate is <=0.1% are used as the solid dispersion medium. With respect to the shape of glass beads, the particle size distribution is set in a range of + or -0.3mm. to a prescribed particle size. A continuously and freely dropped melted glass flow is cut by a fixed edge, which is arranged near the glass flow, and a moving edge which is moved while sliding on the lower face of the fixed edge, and cut glasses are made spherical by their surface tension, thus obtaining wear-resisting glass beads. The particle size distribution of these wear-resisting glass beads is improved considerably. Consequently, admixture of powder of glass beads, crushed matters, or the like is reduced, and the projections are hardly formed on the surface of the magnetic layer, therefore, occurrence of drop-out is prevented, and slipping-off of a ferromagnetic powder from the magnetic layer is prevented.

The level of the triangular signal S2 is euqual to the level corresponding to the standard value of the phase difference between the X axis and the Y axis. Marker signals 4 and 5 are superimposed in the positions corresponding to the amplitude positions of the triangular-wave signal S2 at an inserting section T1, which corresponds to the inserting section of the triangular-wave signal S2. The DC-level signal S3 of the sine-wave signal S1 is inserted into the sine-wave signal S1, and a second inspecting signal SY is obtained. The second inspecting signal SY is supplied to the other input terminal of the X axis or the Y axis. Whether the phase difference is in conformity with the standard value or not is inspected based on the observed waveform and the markers displayed on the tube surface of the oscilloscope.

Consequently, a high purity rare gas, e.g. Kr, Ar or Ne, passes through a piping 14 extending from the second filter layer 13. The gas passing through the piping 14 is then added with a small quantity of F2 and a rare gas, e.g. Kr and/or Ar, fed from a gas source 15 through a piping 16. It is then introduced to the excimer laser generator and circulated to be reused.
