Abstract: PURPOSE: To provide a method for speeding up the measurement of insulation resistance even if an arithmetic means method is used to perform measurements a plurality of times, and conducting arithmetic mean of the results before outputting and for accurately and stably measuring even an ultra-high resistance. CONSTITUTION: In the measurement of insulation resistance using an arithmetic mean method, a measurement times N for arithmetic mean is minimized when the charging current at the initial stage of measurement is large, and also current change is large and the measurement times N for arithmetic mean is increased when the charge current decreases and exceeds a reference value where a measurement current value can be set, thus averaging noise components, and hence reducing a measurement time until the measurement current value reaches a reference value from the initial stage of measurement and speeding up measurement. Also, noise components can be averaged after the measurement current value exceeds the reference value and the measurement value becomes stable, thus achieving an accurate measurement regardless of an ultra-high insulation resistance where the measurement value becomes stable.

Abstract: PURPOSE: To accurately measure humidity with good linearity and high sensitivity by eliminating a memory effect by a constitution wherein a polymer containing a nigrosine and a cellulose is used as a humidity-sensitive film. CONSTITUTION: A quartz vibration humidity sensor 1 is so constituted that electrodes 4 of gold or the like are vaporized on both faces of an AT-cut type quartz vibrator and a humidity-sensitive film 6 is formed on that. A polymer containing a cellulose as a hydrophilic compound and a nigrosine as a hydrophobic compound is used for the humidity-sensitive film 6. The nigrosine is of the hydrophilic compound used as a pigment represented by a specific chemical formula. The cellulose can be one represented by a specific chemical formula or its derivative, e.g. a fatty acid cellulose triester such as cellulose acetate, a mixture compound or an ethyl cellulose is used. The film having the ethyl cellulose and nigrosine causes a good result.

Abstract: PURPOSE:To find a measurable position by avoiding opaque parts so as to reliably identify the kind of plastic used for an article to be inspected by irradiating the article with detecting light while the article is relatively moved to a position detector. CONSTITUTION:Plastic bottles 1 carried on a caterpillar belt 4 are irradiated with light from the irradiating section 3a of a position detector 3. When such opaque parts as labels, printed characters, etc., exist in the barrel sections of the bottles, the absorption spectrum effective to identifying the kind of the plastic used for the bottles 1 is not obtained. Therefore, an analyzer 6 confirms whether or not the received quantity of the light transmitted through the bottles 1 exceeds a preset prescribed value from light receiving signals from a light receiving section 3b. When the analyzer 6 confirms that the quantity of received light is larger than the prescribed value by a prescribed distance, the analyzer 6 decides the position as a discriminated position by judging that the kind of plastic can be identified by measuring the absorption spectrum of near infrared rays by means of the detector 5.

Abstract: PURPOSE:To provide a method and device for restoring a changed electrode potential of a pH measuring electrode using metal oxide or metal for sensitive film to an original potential condition in a short time. CONSTITUTION:Electrode potential-changed pH measuring electrodes 1-4 using iridium oxide for pH-sensitive film are electrically shortcircuitted by electrically connecting their leads 1a-4a to each other, and they are immersed in neutral phosphate solution 5 of pH 6.86 for about an hour. The pH-measuring electrodes of which electrode potential is changed can be restored almost to an original potential condition in a short time to be stabilized, so a very good efficiency is achieved, and because they can be restored to the potential condition where calibration can be performed sufficiently to be stabilized, thereby they can be reused without being wasted and disposed as defectives.
