Title: Current-measuring device
Inventor: TAKAHASHI MASAO
IPC: G01R15/24
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To accurately measure current without removing a conductor by mounting a current path to a conductor to be measured without cutting the current path. SOLUTION: Light from a light source 1 is guided to an optical unit 17 by a transmission fiber 3, is changed into a parallel beam by a lens 11, and is linearly polarized by a polarizer 4. The light is transmitted through a beam splitter 16, enters a sensor fiber 6, is reflected by a reflector 13 of an outlet, and reciprocates in the sensor fiber 6 while a conductor 5 is subjected to Faraday rotation by a magnetic field due to current flowing in the conductor 5. Light being emitted from the sensor fiber 6 is split into reflected light and transmission light on the incidence end face of an analyzer 21. The transmission light is changed into the intensity signal of an X constituent by the analyzer 21, and also the reflected light is changed into the intensity signal of a Y constituent by an analyzer 22.  Each intensity signal is guided to each detector 9 through a reception fiber 8 for converting into an electric signal, and the current is calculated by a signal-processing circuit 10 for outputting.

Filed: 1992-09-14
Abstract: PURPOSE:To obtain an inexpensive and easy liquid vibration wave generator making the molecule activity of a liquid active and enhancing washing force still more by providing a vibration resonance part due to the flow of liquid to a liquid outlet part at the time of the flow of the liquid to apply vibration from low-frequency to high-frequency to the liquid. CONSTITUTION:The high pressure liquid entering from a liquid inflow part 2 is once stagnated in a surface pressure generating hole 5 through a introducing passage 4 and, when a lid is slightly opened by the spring force of a vibration plate 6 and the liquid is discharged, the internal pressure of the surface pressure generating hole 5 is reduced and, therefore, the lid is again closed by the return spring force of the vibration plate 6. When the movement of the vibration plate 6 is extremely rapid, the frequency of vibration transmitted through the liquid also becomes high and, when the movement of the vibration plate 6 is relatively slow, low-frequency vibration transmits through the liquid. By sending an arbitrary vibration wave into the liquid along with the flow of the liquid, the washing effect of the surface of the part in the liquid can be enhanced.
