Abstract: In a case where signals branched from a single reference signal source are transmitted via a plurality of cables, a phase synchronization circuit can be used to stabilize a phase of a signal to be outputted from each cable. However, the phases of signal to be outputted from each cable is affected by combination of a length of each cable and an amount of delay caused by feedback control, so that phases of synchronization signals to be outputted from a plurality of transmission paths are not always the same as each other. In the present invention, since a frequency multiplier that multiplies a frequency of a signal outputted from each transmission path by an even number is provided for a phase synchronization circuit, the phases of the synchronization signals to be outputted from the transmission paths are aligned even when signals are branched from one reference signal.

Abstract: The phase-synchronizing circuit according to the present disclosure includes: a signal source to output a signal; a signal separator to output part of the signal from the signal source as a transmission signal and receive a reflected signal of the transmission signal; a first phase controller to change a phase of the transmission signal from the signal separator according to a control signal; a signal reflector to pass the transmission signal from the first phase controller as an output signal and output part of the output signal as the reflected signal; and a phase comparator to receive part of the signal from the signal source as a reference signal, compare a phase of the reference signal with a phase of the reflected signal from the signal reflector, and output the control signal corresponding to a phase difference between the reference signal and the reflected signal to the first phase controller.

Abstract: A treatment table with which it is easy to perform treatments more appropriately and which is convenient to use is provided. The treatment table includes a head support for supporting the head of a patient, a body support for supporting the body of the patient, and a waist support for supporting the waist of the patient. The head support, the body support, and the waist support are arranged in a longitudinal direction. The head support and the waist support or the body support include a swing unit capable of swing in a width direction about a central position in the width direction. Adjustment operation units for adjusting the swing units are disposed at one concentrated position of the treatment table.
