  • Patent number: 11335491
    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.

  • Patent number: 8833511
    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.

  • Publication number: 20070116861
    Abstract: In manufacturing a display panel of a PDP, a CRT, or the like, for example, a screen stripe is formed on a panel surface in a production cycle time equivalent to or faster than that of a screen printing system. By using a dispenser of a variable flow rate type for a display panel that has an effective display area in which a paste layer is to be formed and a non-effective display area in which no paste layer is to be formed, outside this effective display area, paste discharge is promptly interrupted when a discharge nozzle runs through the non-effective display area of the display panel.
