Abstract: To provide a technique with which an operator, when talking into a microphone, can recognize whether or not his/her voice is being output from a speaker in a scan room, a CT apparatus 1 has: an operator microphone 41 installed in an operation room R2 for receiving a voice of an operator 81; a patient microphone 2 installed in a scan room R1 for receiving a voice of a patient 80; a speaker 50 installed in the operation room R2 for outputting the voice of the patient 80 received by the patient microphone 2; a speaker 5 installed in the scan room R1 for outputting the voice of the operator 81 received by the operator microphone 41; and a light-emitting section 31 for informing, in the case that the patient microphone 2 has received the voice of the operator 81 output from the speaker 5, the operator 81 that his/her voice is being output from the speaker 5.

Abstract: A system power leveling device includes a bidirectional converter connected to a system bus line providing a electric power to a load from a power source and having a first and a second switching element, a power storage device connected to the bidirectional converter, a first specifying section for specifying a power consumption of the load, a charge-discharge control section for controlling the charge and the discharge of the power storage device by controlling the bidirectional converter based on the power consumption specified at the first specifying section, and a second specifying section specifying a current or an electric power of the charge or the discharge.

Abstract: With the object of, when a table unit is moved downward as viewed in a vertical direction by use of an actuator, smoothly moving the table unit and enhancing operability, when the actuator moves the table unit from a first position in the vertical direction to a downward second position, a pressure controller adjusts the amount of fluid held in the actuator on the basis of the first position of the table unit, detected by a position detector to thereby control pressure based on the fluid.
