摘要： An information processing device processes image data representing a distribution of at least one numerical data in a specific space. The information processing device includes a storage unit and an inference unit. The storage unit stores an image recognition program. The inference unit extracts specific information about the at least one numerical data from the image data by executing the image recognition program. A symbol having an appearance corresponding to each of the at least one numerical data is disposed at a position associated with the numerical data in the specific space.

摘要： A signal generation unit outputs a first AC signal and a second AC signal having different phases as noise. A first coaxial cable transmits a first AC signal. A second coaxial cable transmits a second AC signal. A first probe is connected to the first coaxial cable and arranged in proximity to an IC on a printed circuit board to apply the first AC signal to the IC. A second probe is connected to the second coaxial cable and arranged in proximity to the IC to apply the second AC signal to the IC. A determination device determines whether the IC is malfunctioning, based on a state of the IC after application of the first AC signal and the second AC signal.

摘要： A printed circuit board includes a printed board, a first integrated circuit chip, a connector, and a capacitor. The printed board includes a first ground pattern and a second ground pattern directly opposed to the first ground pattern. The second ground pattern is electrically connected with a chassis or connector ground wiring. The capacitor is connected to the first ground pattern and the second ground pattern and disposed on a straight line that defines the shortest distance between the first ground terminal and the second ground pattern.

摘要： A noise filter includes a first capacitor and a second capacitor which are two line-to-line capacitors. Currents flowing through the first capacitor and the second capacitor are in directions opposite to each other, and meanwhile, currents flowing through a first connection wire and a second connection wire are in the same direction and parallel to each other. Accordingly, magnetic coupling is caused between the connection wires and the line-to-line capacitors. Thus, the residual inductance of a line-to-line capacitor itself is reduced, whereby an attenuation characteristic for normal mode noise is further improved.
