Abstract: Viewpoint image DB 120 stores a plurality of viewpoints and images obtained by capturing images of an object from the plurality of viewpoints in association with each other. Data acquisition means 111 reads out viewpoint image DB 120 and supplies it to generation means 112. Generation means 112 uses machine learning model 121 in an initial state or in the middle of training, to generate a virtual image that can be obtained when an image of a virtual object is captured from a virtual viewpoint. Training means 113 compares the images stored in viewpoint image DB 120 with the virtual images generated by generation means 112, and updates machine learning model 121 that is constrained so that the densities at the background point and the virtual viewpoint are each a predetermined constant.

Abstract: An exemplary ship includes a plurality of hybrid systems that drives a propelling machine, and a control device that controls the plurality of hybrid systems. The control device sets the plurality of hybrid systems to the same operation mode.

Abstract: A non-heat treated steel for a crankshaft of the present invention comprises iron (Fe) as a main component and also comprises 0.37 to 0.43 mass % of carbon (C), 0.15 to 0.35 mass % of silicon (Si), 0.90 to 1.30 mass % of manganese (Mn), 0.08 to 0.15 mass % of vanadium (V); and the content of phosphorous (P) is 0.030 mass % or less, the content of copper (Cu) is 0.300 mass % or less, the content of nickel (Ni) is 0.30 mass % or less, and the content of chromium (Cr) is 0.35 mass % or less. The non-heat treated steel also comprises 0.010 to 0.035 mass % of sulfur (S) and 0.02 to 0.05 mass % of bismuth (Bi), which are machinability-improving elements. Thus, the non-heat treated steel has a high fatigue strength and a high yield strength and also has an excellent machinability.

Abstract: The present invention provides a steel material which is excellent in both of the strength (particularly, fatigue strength) and the manufacturability (particularly, bending straightening properties), and thus can be used as an automobile component such as a crankshaft by being formed into a product shape, being subjected to a high strength treatment such as a nitrocarburizing treatment, and then being subjected to the bending straightening.

Abstract: A ship includes an out-drive unit that exerts a propulsion force on a ship hull by power from an engine; a detection device for detecting a current position, a bow direction, and a moving speed of the ship hull; a brake pedal that limits a moving speed of the ship hull; a brake sensor that detects a foot-pushing amount on the brake pedal; and a ship steering control device connected to the out-drive unit, the detection means, and the brake sensor. The ship steering control device acquires an operating status of the out-drive unit and detection results obtained by the detection device and the brake sensor, and controls the out-drive unit based on the detection results. The ship steering control device changes the output of the out-drive unit in accordance with a foot-pushing amount on the brake pedal.
