In determining a condition of a case under which the occurrence rate of the performance abnormality is high based on information related to a resource utilization situation acquired in a resource utilization situation acquisition step and an occurrence frequency of a request acquired in a request occurrence frequency acquisition step, and information related to the existence/nonexistence of the performance abnormality determined in a performance abnormality existence/nonexistence determination step, when branching a parent node that represents a situation of a decision tree to two child nodes using the method of decision tree, the decision tree is generated using an evaluation function which performs branching such that most of normal samples which belong to the parent node are contained in the one child node, and most of abnormal values which belong to the parent node are contained in the other child node.

An imaging apparatus includes a first pixel generating a signal by photoelectric conversion, a second pixel arranged in the same row as the first pixel and generating a signal by photoelectric conversion, a first comparator comparing the signal based on the first pixel with a first reference signal having a level changed according to passage of time, and a second comparator comparing the signal based on the second pixel with a second reference signal having a rate of change for passage of time different from that of the first reference signal. In addition, a first counter counts until the first comparator outputs a signal indicating inversion of magnitude relation of the signal based on the first pixel and the first reference signal, and a second counter counts until the second comparator outputs a signal indicating inversion of magnitude relation of the signal based on the second pixel and the second reference signal.

A fuel injection device 1A includes a nozzle body 10 equipped with multiple injection apertures 12, a needle valve 20 arranged in the nozzle body, a fuel swirl portion 24 in which fuel FE is swirled along an inner wall surface of the nozzle body, and a guide portion 22 applying swirl force to the fuel and then guiding the fuel to the fuel swirl portion, the fuel swirl portion being arranged at a position at which the fuel swirl portion partially overlaps with the injection apertures. When the needle valve is at a low lift position, the fuel swirl portion overlaps with parts of the injection apertures so that the shape of sprayed fuel can be formed in diffusive spray having a wide spray angle. When the needle valve is at a high lift position, the shape of sprayed fuel can be formed in column-shaped spray having a narrow spray angle.
