A positive electrode side input loop line () and a positive electrode side output loop line (), and a negative electrode side input loop line () and a negative electrode side output loop line () form two sets of coupling loops, and the loop lines of the two sets have the same winding direction, and have the same loop sizes of and relative relationship between the loop lines. A capacitor () is connected in series between the positive electrode side input loop line () and the negative electrode side input loop line ().

Noise filter circuit

Solar cell for artificial satellite

A transmission circuit, mounted on a printed board and having attenuation characteristics, to attenuate an amplitude of a reception signal according to the attenuation characteristics, and to transmit the amplitude-attenuated reception signal, as an attenuation signal; and a correction circuit, mounted on the printed board and having correction characteristics, to attenuate an attenuation signal that has been received from the transmission circuit according to the correction characteristics, and to transmit the attenuation signal attenuated, as a correction signal are provided. The attenuation characteristics are such characteristics that the ratio of the amplitude of the attenuation signal to the amplitude of the reception signal decreases as the frequency of the reception signal increases. The correction characteristics are characteristics with which the ratio of the amplitude of the correction signal to the amplitude of the attenuation signal increases as the frequency of the attenuation signal increases.

Processing circuit and signal correction method

A package includes a main unit having formed therein a through hole that penetrates the package from a first surface to a second surface; and a connection terminal that is provided inside the through hole. The second surface is a bottom surface of the main unit, and has an electric circuit incorporated therein. The connection terminal is electrically connected to the electric circuit incorporated in the main unit, and configured to be contactable by an insertion target that is inserted in the through hole from a side of an inserting direction.

Package

A logic circuit for board power-supply evaluation to be incorporated into a logic device loaded on a product board includes a circuit that simulates an operation of the logic device so that utilization rate is variable at an arbitrary frequency by use of a predetermined circuit in all available logic elements of the logic device; a circuit that judges normality/abnormality of an operation of the operation simulation circuit; a utilization control circuit that varies and controls utilization rate of the logic device by controlling execution of an operation of the operation simulation circuit based on a judgement result of the operation judgement circuit and sets a utilization rate when the operation simulation circuit is instructed to stop the operation; and a utilization output circuit that outputs the judgement result of the operation judgement circuit and the utilization rate set by the utilization control circuit to the outside.
