Abstract: An induction heated roll apparatus includes a roller main body, an induction heating mechanism, and a cooling mechanism. The induction heating mechanism heats the roller main body, while the cooling mechanism cools the roller main body and/or the induction heating mechanism using a cavity portion between the roller main body and the induction heating mechanism. The cooling mechanism has intake apertures and discharge apertures that are formed in a journal flange portion and communicate with the cavity portion, a suction mechanism that suctions a gas in the cavity portion through the discharge apertures, and a mist supply mechanism that supplies mist to the intake apertures.

Abstract: A movable member coupled to a displacement detector via a void is disposed with respect to a fixed member to which a coil is fixed. By disposing the coil in a closed loop magnetic circuit including a permanent magnet, the movable-side member, and the fixed member, a Lorentz force for moving the movable-side member in the axial direction is generated.

Abstract: The present invention controls the pressure and flow rate of fluid, in order to obtain uniform performance, configure a closed loop magnetic circuit so as to include an electromagnet, a flapper, and a yoke material, and elastically deform the flapper itself by Maxwell attractive force generated between a magnetic pole of the electromagnet and the flapper to make the separation distance between the nozzle and the flapper variable. As opposed to a rigid flapper structure that swingably moves around a supporting point, like a conventional servo valve, the electromagnet, the magnetic pole, the nozzle, the flapper, and the like are arranged such that a change in magnetic gap directly leads to a change in air gap.

Abstract: In a conventional hard material insulator, reproduced sound can be tuned with use of characteristics of the material; however, various types of acoustic materials have specific high frequency characteristics, and thus their acoustic effects lack versatility, require compatible audio devices, and change with environment, musical genre, etc. To address this, a wind-bell member (resonant member) is arranged in parallel with a main propagation path of vibration transferred from an audio device to an insulator. Accordingly, a vibration system of a wind-bell having a tone determined by many factors such as a fundamental tone, harmonic tones, lingering sound, and fluctuation assists (enhances) high frequency vibration propagated from the audio device. As a result, due to the above assist action that is different in principle from a conventional type, acoustic characteristics such as a sense of localization, resolution, and a sense of transparency and scale a sound image can be dramatically improved.
