摘要：【課題】機械駆動系の摩擦と関係するディスプレーサの下降速度を定期的に測定し、構成部品の劣化の診断を行う。【解決手段】ディスプレーサが定速度で下降中の定速度V2を測定する(ステップS11)。得られた定速度V2を記憶媒体に記録する(ステップS12)。定速度V2が劣化規定値Δvを超えて低速となれば、前回までの履歴過程と比較し、その劣化の度合を判断する(ステップS13)。定速度V2が劣化規定値Δvを超えて低速となれば、一応、劣化が発生している可能性がある(ステップS14)。劣化の可能性がある場合には、前回までの定速度V2の経時変化を直線又は曲線から成る近似線に近似して(ステップS15)、今回得られた定速度V2がこの近似線の延長線上にあるかを確かめる(ステップS16)。定速度V2が近似線の延長線上にあれば劣化が生じていると判断する(ステップS17)。【選択図】図5

摘要： PROBLEM TO BE SOLVED: To provide a device for measuring an oil level that fluctuates constantly and displaying it on an indicator. SOLUTION: By adopting a planetary gear mechanism where grease oil is filled for driving a take-up drum 17, conflicting operations can be made where the take-up drum 17 idles when the float goes down and a suspension string 4 is taken up by a motor when the float goes up and the suspension string 4 slacks. Then, tension is given to the suspension string 4 by a movable arm 20 with a proper weight being mounted to an idler 23 and the viscosity of grease oil being filled into the planetary gear mechanism, slippage between a pulley 7 and the suspension string 4 is prevented, the operation of the on/off of a limit switch 24 is simplified by converting the slack of the suspension string 4 to the move of the movable arm 20, and visibility is improved by transferring the move of the pulley 7 to an indicator 2 by a worm and a worm wheel 12.

摘要： PURPOSE:To correctly and reliably measure a liquid level irrespective of deterioration in electric characteristics due to a change with time as well as an influence of temperature and humidity. CONSTITUTION:Reference voltage V0 and measured voltage V1 of a potentiometer 22 are alternately transmitted while being changed over by a switch 23 to convert them into frequencies f0, f1 corresponding to voltage levels input by a voltage/frequency conversion means 24, and these frequencies f0, f1 are converted into digital signals d0, fa1 by a frequency/digital conversion means 25. Thereafter their ratio Nj=fd0, fd1 is calculated in a calculation means 26, a ratio Ni already stored in a memory means 27 is compared with the ratio Nj output from the calculation means 26, and if an absolute value of the difference DELTAN=Ni-Nj is a predetermined value or larger, the level data is transmitted from a transmitting means 42 via an antenna 43.
