There is provided a pit initiation evaluation system or the like capable of predicting pit initiation effectively and at low cost. In a pit initiation evaluation system of an embodiment, a pit initiation evaluation unit creates and retains, based on a dry-wet alternate time data, a deposit impurity concentration data, and a pit initiation data on pitting corrosion initiated in each of a plurality of turbine stages when an operation is actually performed in the steam turbine, a pit initiation evaluation table presenting a relationship between a dry-wet alternate time, a deposit impurity concentration, and pit initiation. Further, the pit initiation evaluation unit is configured to evaluate, by using the pit initiation evaluation table, pitting corrosion to be initiated in each of the plurality of turbine stages in an operation planned for the steam turbine.

An aperture device actuated by a shape memory alloy wire controls two overlapping shuttering surfaces. The two shuttering surfaces control the amount of light transmitted through a lens assembly. The shape memory alloy wire is actuated by a flexible printed circuit which controls a lever slotted to both shuttering surfaces. By Joule heating, the electric current controls the shape of the wire, actuating the aperture device.

An electronic device according to a first aspect comprises an imaging device and a processor. The imaging device has a predetermined imaging region, and is configured to capture images having different focal distances. The processor is configured to execute a first process of identifying two or more focus identification regions included in a first imaging region included in the predetermined imaging region by comparing the captured images in the first imaging region, and a second process of interpolating a focal distance of a middle region not belonging to the two or more focus identification regions in the first imaging region. The second process includes a process of interpolating the focal distance of the middle region based on a focal distance of an interpolation focus region that is located inside or outside the middle region and that is one of the two or more focus identification regions.

Electronic device, method, and program

A device for manufacturing a layered object includes a container, a vibration unit, and an energy beam irradiation unit. The container includes a stage, a wall surrounding the stage, and a lid. The vibration unit vibrates raw material powder to planarize a face of the raw material powder supplied into the container. The energy beam irradiation unit irradiates part of the raw material powder with an energy beam to form part of the layered object. The lid presses the raw material powder when the vibration unit vibrates the raw material powder. A space is formed between the wall and the lid in the container when the lid is in contact with the raw material powder. The raw material powder is allowed to flow into the space.
