Title: Oil leakage detecting method for of cable line
Inventor: MURAKAMI KAIHEI
IPC: G01M3/28
Filed: 1990-08-08
Abstract: PURPOSE:To judge the presence or absence of oil leakage by plotting a regression line on the correlation diagram for oil amounts in two oil feeding sections, computing the approximated oil amount in one oil feeding section based on an actually measured oil amount in the other section, and checking the difference between the actually measured oil amount and the approximated oil amount. CONSTITUTION:In an OF cable line wherein the oil feeding section is divided into a plurality of sections, a regression line is plotted based on the actually measured values of oil amounts X and Y in the normal state of the first section and the second section. Then, the line is expressed by Y = aX + b. Thereafter, the actually measured oil amount (y) in the first section and the actually measured oil amount (x) in the second section are used, and the approximated oil quantity y' = ax + b is obtained from the regression expression. The difference D = y - y' is operated. The average value of the values D and the standard deviation sigma are obtained, and whether ¦D¦ exceeds the control limit 3sigma or not is judged. In the case of YES, medium and small leaking-oil warnings are issuded. In this way, the medium and small leaking oil states can be detected without the effect of the oil-amount fluctuation due to load fluctuation and temperature change.

Thereby the correlation between a reflected light and the reference light is made maximum, an output of HPF 16 of a synchronous detection output turns zero and a distance to the target is calculated with high resolution from the number of bits of delay detected by a controller 17. At the same time, a Doppler frequency shift component corresponding to a relative speed of the target is generated at a high signal level in a low-frequency component of the synchronous detection output. Therefore discrimination 18 is made with excellent S/N and the relative speed of the target can be calculated.

Abstract: PURPOSE:To eliminate a beat disturbance generated at the time of reproduction by adding that which delays a reproducing luminance signal by a 2H period and that which does not delay it, when reproducing a video signal recorded by frequency-multiplexing a luminance signal and a color signal. CONSTITUTION:At the time of reproduction, signals from video heads 7, 8 are supplied to a switching circuit 14 through head amplifiers 12, 13, respectively. Subsequently, a luminance signal component in an output of the switching circuit 14 is demodulated to a luminance signal by an FM demodulator 15, and thereafter, is provided to a comb line filter 16. The filter 16 delays the provided luminance signal by a 2H period, and also mixes a delayed luminance signal and an undelayed luminance signal. In this case, as for a beat disturbance component, since the phase is inverted at every 2H period, the disturbance component is cancelled by the filter 16. In this way, a beat disturbance generated at the time of reproduction can be eliminated.

Filed: 1990-08-11
Abstract: PURPOSE:To reduce attitude errors resulting from a convection by thermally coupling parts of two sensor coils at the far side of a conduit by a heat conductor and heating the heat conductor by a heater. CONSTITUTION:Sensor coils 4, 5 are thermally coupled each other by a heat conductor 11 heated by a heater 15. The attitude errors due to a convection in a sensor part 6 can be reduced. Moreover, the heat distribution at the coils 4, 5 becomes sharp and the response is improved remarkably. A fluid running in a conduit 1 is preheated by a leg part 12 of the heat conductor 11 provided outside the upper coil 4, and therefore the heat exchanging amount in the sensor part 6 in enough to be small. Even when the flow rate of the fluid is increased, the heat exchange is performed smoothly and the linearity of an output signal to the flow rate is held good. The range of the flow rate where the flow rate is linearly proportional to the output signal is enlarged remarkably and the measurable area of the flow rate is widened.

Abstract: PURPOSE:To approximate an area shape in a polygon with less code quantity and to facilitate the adjustment of the code quantity. CONSTITUTION:A threshold level of an allowable error of a polygon is decided from a permissible code quantity for expressing an area shape (100). Taking notice of one side of an approximated polygon, as to a cross point through extended two-sides adjacent to the noted side, the side is removed and the cross point is used for a new apex of the approximated polygon and the approximated error is measured (102-104). A side minimizing the approximated error is selected (102-107) and when the approximated error is less than the threshold level, the side is removed and the cross point is used for a new apex for the approximated polygon (108, 109). The processing above is continued till a side able to be removed is lost (101-109).
