Filed: 1988-04-12
Abstract: PURPOSE:To estimate a distance easily to a leak point easily, by inputting an average frequency of vibration at a measuring point to compute a frequency attenuation characteristic of a pipeline as known data. CONSTITUTION:An AC signal measured with a vibration sensor 8 undergoes a calculation of an average frequency with an average frequency measuring device 9, an output of which is inputted into an average frequency inputting means 1 through a transmission line 7. Then, specifications of a water supplying/ distributing equipment and material which composes a vibration propagation path from a leak point to a measuring point are inputted from a water supplying/distributing specifications inputting means 2. Proper average frequency attenuation coefficient and average frequency propagation coefficient are stored into a constant file 3 classified by specifications of the water supplying/ distributing equipment and material. A computing means 4 calculates a distance between the measuring point and the leak point from a measured value of the average frequency and the attenuation coefficient and propagation coefficient proper to the water supplying/distributing equipment and material composing the propagation path.

Title: Method of and apparatus for detecting concentration of metal ion
Inventor: OKUDAIRA HIROAKI
IPC: G01N27/26
Filed: 1981-06-10
Abstract: PURPOSE:To detect the concentration of a metal ion by adding a complexing agent to a liquid while measuring the concentration thereof in the liquid. CONSTITUTION:A fixed amount of a liquid to be detected is placed into a reactor 3 and the concentration of a metal ion in the liquid is measured as potential of an ion selective electrode 8 while adding a solution 6 (of known concentration) of a complexing agent which reacts the metal ion to form a complex to the liquid gradually. During the adding of the complexing agent, a time at which the potential of the electrode 8 changes suddenly is checked to detect the concentration of the metal ion from the amount of the complexing agent added. The logarithm of the concentration thereof has a linear relationship with the potential of the ion-responsive electrode and the potential of the electrode suddenly changes at a point where the metal ion is equivalent to the complexing agent thereby enabling accurate measurement of the concentration of the metal ion in the liquid being detected.

When an abnormality takes place in the response output of the device 50 for the pattern data from the generator 10, the external signal via the buffer 70 turns to 1 to be latched into a register 80 at the rising of the subsequent clock and an address controlling circuit 90 provides an address for branching off in response thereto. Thus, an external corresponding pattern is outputted from the generator 10.

Abstract: PURPOSE:To reduce linking loss and to make linking operation easy by making a needle crystal of single crystal grow epitaxially on a substrate of single crystal. CONSTITUTION:In a shown production equipment, a single crystal 1 of the 1st metal on which a very small piece of the 2nd metal is stuck is set.

If a vapour pressure of atoms of the 1st metal in a gaseous phase comes to supersaturation, the atoms of the 1st metal move into an alloy melt phase, and, before long, the atoms of the 1st metal in the alloy melt phase come to an excess. If, at this time, the temperature of the alloy melt is fixed, a composition of the alloy melt dosn't change, then excess atoms of the 1st metal is deposited on the single crystal 1 of the 1st metal of the solid phase to crystalize epitaxially. Whereby, the alloy melt phase of the 1st- and the 2nd metals is raised upward, and the needle single crystal of the 1st metal whose size is depending on a size of a liquid drop of the alloy melt is formed, thereby, a coupler of a core clad structure is obtained.
