摘要： For enabling to prevent ill effects from being generated in the structures of a reflection mirror, even if increasing an output energy from a light source, thereby preventing ill influences from being exerted on the driving condition thereof, a mirror drive controller unit 7 reads out history data of the past, relating to temperature changes on a micro mirror 1, from a first LUT holder unit 19. Upon basis of the read-out history data of the past is presumed the temperature on the micro mirror 1 at the present time. The presumed temperature on the micro mirror 1 is temperature P temp of the micro mirror 1 at the present time, and upon that P temp are changed vibration (or oscillation) condition of the micro mirror 1 in the horizontal (H) direction and vibration (or oscillation) condition thereof in the vertical (V) direction.

摘要： The present invention provides a technique for maintaining a function for effectively blocking common mode noise with a simple configuration, even in the case where unbalance occurs in characteristic impedance of a coaxial cable in an MRI apparatus, and improving the performance of an RF coil. In a circuit where a balun is established by parallel connection with the coaxial cable, multiple serial resonance circuits having different resonance frequencies are connected in parallel. A value of each constitutional element of each of the serial resonance circuits is adjusted in such a manner that the frequency for blocking the common mode noise of the entire balun falls into a range between the resonance frequencies of these serial resonance circuits.
