  • Patent number: 9444319
    Abstract: An electric rotating machine includes a power transmission mechanism and an armature. The power transmission mechanism is equipped with a first, a second, and a third rotor. The first rotor includes n soft-magnetic members. The second rotor includes k soft-magnetic members. Note that n and k are an integer more than one. The third rotor is made up of magnets whose number of pole pairs is m where m is an integer more than or equal to one. The armature faces the third rotor. The first, second, and third rotors are arranged so as to establish a magnetic coupling among them. The soft-magnetic members of the first and second rotors and the magnets of the third rotor meet a relation of 2m=|k±n|. This arrangement is capable of achieving the transmission of power regardless of electric energization of the armature.

  • Publication number: 20160061964
    Abstract: A radiation image detecting device includes a photodetecting element that detects fluorescence light, and a prism that is disposed on an optical path of excitation light traveling toward an imaging plate and between the photodetecting element and the imaging plate. The prism includes, as surface thereof, a side face that is opposed to the imaging plate, and a side face and a side face that are inclined relative to the side face. The prism is disposed so that the excitation light incident through the side face propagates inside and is output from the side face and so that reflection from the imaging plate incident through the side face propagates inside and is output from the side face. The photodetecting element is disposed so as to be opposed to a region different from a region where the reflection from the imaging plate is output, in the surface of the prism.

  • Publication number: 20150211935
    Abstract: In a composite sensor, an arrangement region of thermal image sensors and an arrangement region of range image sensors are arranged so as to overlap each other as seen in the mounting direction. This makes it possible to acquire thermal and range images coaxially, thereby suppressing image misalignment between the thermal and range images. In the composite sensor, a seal body formed by mounting the first and second substrates on top of each other seals a space about the thermal image sensors in a vacuum state. This can prevent the heat occurring about the range image sensors from affecting the thermal image sensor side. In addition, the substrate arranged with the thermal image sensors and the substrate arranged with the range image sensors are separate from each other, which can secure a degree of freedom in designing.

  • Patent number: 8860274
    Abstract: In a double-stator motor has a rotary shaft, an annular rotor is coupled with a rotary shaft. First and second three-phase stators are arranged inside and outside to the rotor in the radial direction and formed to generate first and second rotating magnetic fields in response to three-phase currents, respectively. The rotor has an even number of segment poles made of soft magnetic material and arranged mutually separately at positions of the rotor. The positions are equally distanced apart from the rotary shaft in the radial direction and in the circumferential direction. Each of the first and second three-phase stators has magnetic poles which are the same in the number of poles as the segment poles and the magnetic poles are positioned such that magnetomotive forces from the magnetic poles are faced to each other between the magnetic poles of the first and second three-phase stators.
