Abstract: Trial manufacturing condition proposing system includes a characteristic evaluation data preprocessing unit, a feature value selection processing unit, a regression model creation processing unit, and a trial manufacturing condition proposing processing unit. The characteristic evaluation data preprocessing unit applies preprocessing to the characteristic evaluation data indicating an evaluation result of characteristics of the material. The feature value selection processing unit executes feature value selection processing on the characteristic evaluation data to which the preprocessing has been applied. The regression model creation processing unit executes regression model creation processing on the characteristic evaluation data, to which the preprocessing has been applied, based on the result of the feature value selection processing.

Abstract: A mobile terminal includes: a processor that acquires a type of a product sold by weight; and a transceiver connected to the processor and that establishes intercommunication with a weighing device that weighs the product sold by weight; a storage connected to the processor. The processor causes the transceiver to acquire, from the weighing device, a weight value of the product sold by weight weighed by the weighing device. The processor registers, in the storage, the type of the product and the weight value that corresponds to the type of the product.

Abstract: An inner ring of a pipe joint includes a first tapered surface formed at one axial end portion of an inner circumferential surface such that a diameter thereof gradually increases from another axial side toward one axial end thereof in a state before a bulge portion is press-fitted into an end portion of a tube. A diameter increase starting point of the first tapered surface is located in a range from a deformation starting point, which serves as a starting point from which an inner circumferential surface is deformed due to the bulge portion receiving external force from the tube when the bulge portion is press-fitted into the end portion of the tube, to a position, on the inner circumferential surface, corresponding to one axial end of an outer circumferential surface of a body portion.

Abstract: A weighing and pricing device includes: a processor that executes a registration process for a product to be purchased by a customer; a transceiver that: establishes a connection between a mobile device possessed by the customer and the weighing and pricing device; and upon establishing the connection, receives, from the mobile device, identification information that identifies the mobile device; and a storage that stores information relating to the product and the identification information in association with each other. After the registration process is interrupted, the transceiver receives, from the mobile device, identification information. The processor specifies the product associated with the stored identification information that corresponds to the identification information received after the registration process. The processor recommences the registration process for the specified product.
