摘要： An embodiment of the process state analysis device of the present invention is provided with an evaluation value calculation unit and a graph creation unit. The evaluation value calculation unit calculates, within an evaluation value calculation range indicating a target range for calculating evaluation values, an evaluation value for each cluster that is classified on the basis of multi-dimensional process data output from each measurement device. The graph creation unit determines a hue for a graph element for each cluster on the basis of the evaluation value for the cluster as calculated within the evaluation value calculation range, and on the basis of a color reference evaluation value corresponding to a reference hue for the graph element, and creates and outputs a graph representing, for each aggregation unit time interval in a specified display period, the number of nodes belonging to each cluster.

摘要： In order to realize stable quality control, provided is a quality control device (1) having an input device which receives data such as an operation condition of each device (21) to (26) in a production system (20) for producing a product; a calculation unit which assigns a value of the operation condition to a correlation formula calculated in advance and calculates a value derived from the correlation formula; and a determination unit which performs good or bad determination on a quality of a workpiece in each process, on the basis of a result calculated by the calculation unit. Further, when “bad” is determined as a result of the good or bad determination, the quality control device (1) calculates an appropriate value of the operation condition and sets the value to each device (21) to (26).

摘要： Provided are an optical sensor and an analyzer, including an optical sensor section in which a cladding layer of an optical fiber is removed so as to expose a core layer by a predetermined optical path length, and a protective material is added to a surface of the exposed core layer, the protective material having higher resistance to an organic solvent, base, or acid than that of the cladding layer; a light source device that causes light to enter one end of the optical fiber; a light receiving device that receives transmitted light emitted from another end of the optical fiber; and a control device that controls the light source device and the light receiving device to measure optical transmittance in the optical sensor based on a ratio of intensity of the light emitted from the light source device to intensity of the light received by the light receiving device.

摘要： Provided herein is a fuel rod and a fuel assembly for light water reactors in which crack penetration to a fuel cladding tube or an end plug can be prevented even when cracking occurs at the joint between the fuel cladding tube and the end plug for which a ceramic base material is used. A fuel rod 10a for light water reactors includes: a cylindrical cladding tube 11 formed of a ceramic base material; a connection 21 formed of the same or similar material to the cladding tube 11; and an end plug 12a having a concave portion 12f of a continuously curved surface shape adapted to house the connection 21. The end plug 12a is formed of the same or similar material to the cladding tube 11. A slanted surface 11a formed at an end portion of the cladding tube 11, and a slanted surface 12d formed at an end portion of the end plug 12a are joined in contact with each other with a metallic joint material 20. The joint is supported by the connection 21.
