Abstract: A magnetically shielded room reducing pressure felt by a person inside includes an upper shielding body, a side periphery shielding body, and a lower shielding body, all of which define a magnetically shielded inner space. A magnifying lens is located in the upper shielding body. The magnifying lens can magnify and project an incident image from outside to a range of one inner side surface of the magnetically shielded room. so that the range should be 50% or more of the area of the one inner side surface. The range includes most of the area above a line of sight of a person in the magnetically shielded room. The magnifying lens is provided at a position closer to the one inner side surface as a projection target of the lens than the other inner side surface as a non-projection target facing the one inner side surface as the projection target.

Abstract: To prevent a wrap-around signal from an output detection circuit unit that occurs when commonality is achieved between the power supply of the output detection circuit unit and the bias power supply of a power amplification unit. When commonality is achieved between the power supply of a diode of an output detection circuit unit and the power supply of a bias circuit, a resonance circuit is connected between the bias circuit and the output detection circuit unit, thereby preventing a wrap-around signal from the output side of a power amplification transistor from being input to the input side of the power amplification transistor.
