Abstract: A centrifugal blower includes a case, an electric motor supported by the case at a motor support position, and a fan driven by the electric motor. The fan includes: a boss installed to an output shaft; a main plate extending outward from the boss in a radial direction; a plurality of blades extending from the main plate toward one side in an axial direction; and a side plate joined to an end portion of each of the plurality of blades, which faces the one side in the axial direction. A weight of the main plate is larger than a weight of the side plate. The main plate and the side plate are both inclined toward another side opposite to the one side in the axial direction as the main plate and the side plate approach an outer side in the radial direction.

Abstract: A centrifugal blower includes a plurality of blades, a shroud, a main plate and a tubular portion. An air flow passage is formed between each adjacent two of the blades. When the blades are rotated, air, which is suctioned from one axial side into a suction port is conducted through the air flow passage and is radially outwardly discharged. The shroud has a cover region, which faces another axial side and is shaped in a convex arcuate form. An axial end part of the tubular portion, which faces the one axial side, has an end surface. The end surface and a second virtual line are parallel to each other, or a distance, which is measured between the end surface and the second virtual line in the axial direction, is progressively increased from a radially inner part to a radially outer part of the end surface.

Abstract: A non-transitory computer-readable recording medium stores a management program for causing a computer to execute processing including: acquiring information regarding a usage status of a first memory for data transfer included in a measurement target from each of a plurality of the measurement targets; calculating priority of data transfer of each of the plurality of measurement targets, based on the acquired information regarding the usage status of the first memory; collecting measurement data from the first memory of any one of the plurality of measurement targets, based on the calculated priority; and storing the collected measurement data in a second memory that stores measurement data output to a data processing unit that processes the measurement data of each of the plurality of measurement targets.

Abstract: A non-transitory computer-readable recording medium stores an information processing program for causing a computer to execute processing including: at each predetermined time point, measuring a first type of a feature value regarding the corresponding time point; calculating an accumulated difference value from a first feature value regarding a first time point to a second feature value regarding a second time point after the first time point, among the measured feature values; and determining whether or not the second feature value is set as a transfer target to be transferred to a storage destination on the basis of a result of comparing the calculated accumulated difference value with a threshold.
