Abstract: A moisture content measurement method that calculates moisture content of dehydrated sludge using a calibration curve for calculating the moisture content of the dehydrated sludge, the calibration curve being obtained by performing multivariate regression analysis after first-order differential processing or an offset correction is performed on absorbance for reflected light or reflectance for infrared rays from dehydrated sludge, the absorbance or the reflectance being obtained by measuring the dehydrated sludge using an infrared measurement apparatus provided with a light-receiving unit that can receive at least infrared rays reflected from a target object to be measured and a light source that has a plurality of infrared LEDs that can emit infrared rays having respectively different wavelengths or a light source having an infrared-region tungsten lamp or halogen lamp.

Abstract: A semiconductor chip includes: a substrate; a first bump electrode formed on one face of the substrate; a second bump electrode formed on other face of the substrate; and a conductive bonding material layer formed on a top face of at least one of the first bump electrode and the second bump electrode. The first bump electrode has a convex top face and the second bump electrode has a concave top face.

Abstract: To propose a patent value evaluating device capable of identifying the causal association with business activity.

Abstract: A method for detecting a connector disengagement of an optical fiber amplifier and a transmission optical fiber connected thereto, the optical fiber amplifier including a doped optical fiber and a pumping light source, and a transmission optical fiber including at least one connecting portion connected to an output of the optical fiber amplifier, includes the steps of: measuring a reflection from the transmission optical fiber to the optical fiber amplifier; and comparing the reflection to an allowable range between a first threshold that is greater than a predetermined reflection in the absence of a connector disengagement, and a second threshold that is smaller than the predetermined reflection in the absence of a connector disengagement; determining that there is no connector disengagement when the measured reflection is within the allowable range; and determining that there is a connector disengagement otherwise.
