摘要： An X-ray apparatus in this example of the invention includes a compression unit that enables to move independently of an X-ray tube supporting device and an X-ray detector for compressing a region of interest of a subject; and a connecting part for connecting the X-ray detector to the compression unit and disconnecting the X-ray detector from the compression unit. Consequently, when the compression unit is not used, the compression unit is located in a retracted position. Thus a space can be secured around the subject placed on a top board. On the other hand, when the compression unit is used, the connecting part connects the X-ray detector to the compression unit. Thereby a compression member of the compression unit can always press a site of interest of the subject at the center of a detecting surface of the X-ray detector.

摘要： The present invention aims to provide an angular velocity detection device which is capable of reducing the effect of coupling between a drive electrode and a first displacement detection electrode by a floating capacity, and is low in cost. In the angular velocity detection device, an oscillating body 21 is displaceable in a first direction and a second direction which orthogonally intersect each other. The oscillating body 21 is oscillated in the first direction by an electrostatic force corresponding to a drive signal generated by a non-interference signal generator 1. A carrier signal generated by the non-interference signal generator 1 is applied to the oscillating body 21. A first displacement detection circuit 3 and a second displacement detection circuit 4 each detect a displacement of the oscillating body 21 as a displacement modulation signal indicative of a change in electrostatic capacity synchronized with the carrier signal to thereby detect an angular velocity. Here, the frequency of the drive signal and the frequency of the carrier signal are set so as to be generated at such a frequency ratio that a higher harmonic of the drive signal multiplied by an odd number does not the displacement modulation signal.

摘要： An improved DC-DC converter with reduced input current ripples. The converter includes a transformer, a switch, and a capacitor. The switch turns on and off alternately to store the energy in the transformer. The capacitor is connected in series with a rectifier and a secondary winding of the transformer across an input DC voltage so as to be charged by the energy released from the secondary winding through the DC power source. Accordingly, the circuit sees an input current which continues flowing through the DC power source even the switching element is turned off.
