  • Patent number: 7748914
    Abstract: A single-lens reflex camera has a first image pickup device as a main image pickup device, a second image pickup device for live-view observation, a reflection mirror which switches an optical path between an optical path directed toward the first image pickup device and an optical path directed toward the second image pickup device, and a control section. When the shooting operation is instructed with the second image pickup device driven and a live-view displayed, the control section starts driving the reflection mirror to retract the reflection mirror from the optical path, and stops the second image pickup device and starts driving the first image pickup device while the reflection mirror is driven in a retracting direction.

  • Publication number: 20100164663
    Abstract: [Object] One object of the present invention is to provide a method for manufacturing a permanent magnet which can effectively improving the magnetizing properties and coercive force with efficiently diffusing Dy into grain boundary phases without deteriorating a surface of sintered magnet of Nd—Fe—B family and does not require any subsequent working process. [Means for achieving the object] Sintered magnet S of Nd—Fe—B family and Dy are arranged in a processing chamber 20 apart from each other. Then Dy is evaporated by heating the processing chamber 20 under a reduced pressure condition to evaporate Dy with elevating the temperature of sintered magnet S to a predetermined temperature and to supply and deposit evaporated Dy atoms onto the surface of sintered magnet S.

  • Publication number: 20090201106
    Abstract: A harmonic suppression resonator comprises a plurality of waveguide resonators that resonate in TE mode, in which harmonic suppression resonator, adjoining resonators are coupled via a plurality of coupling windows. Four coupling windows 33bc1, 33bc2, 33bc3 and 33bc4 are provided between a resonant region 51b and a resonant region adjoining the resonant region 51b. These coupling windows allow fundamental wave modes of the adjoining resonators to be coupled mainly by magnetically coupling. The coupling windows 33bc3 and 33bc4 allow second harmonic modes of the adjoining resonators to be electrically coupled, and the coupling windows 33bc1 and 33bc2 allow the second harmonic modes of the adjoining resonators to be magnetically coupled. By causing the amount of the electrically coupling and the amount of the magnetically coupling to be substantially equal, the coupling of the second harmonic modes is negated, whereby propagation of the second harmonic is blocked.
