  • Publication number: 20110111602
    Abstract: Disclosed is a plasma processing method that excels in mass production consistency as it suppresses the flaking of a reaction product deposited on a portion outside the effective range of a Faraday shield in a vacuum vessel. The plasma processing method, which plasma-processes a sample having a layer made of an etch-resistant material by using a plasma processing apparatus having a discharger and a processor, includes a first step of performing an aging process that is to be performed before etching the sample, a second step of performing etching by plasma-processing the layer that is made of an etch-resistant material and formed on the sample, a third step of stabilizing a film deposited on the inner wall of a chamber forming the processor by performing plasma processing after the second step, and an additional step of repeating the second step and the third step.

  • Publication number: 20110092524
    Abstract: The invention relates to a pharmacological action of a compound which functions as a PPAR? agonist on the barrier function of the corneal epithelium. A PPAR? agonist such as rivoglitazone, DRF-2593, GW-544 or BMS-298585 exhibits an excellent effect of enhancing the corneal epithelial barrier function in a test for enhancement of corneal epithelial barrier function, and therefore is useful as a preventive agent or a therapeutic agent for ocular infection or ocular unidentified complaint caused by a decrease in the corneal epithelial barrier function. Further, the PPAR? agonist can enhance the corneal epithelial barrier function of diabetic patients, patients with decreased corneal epithelial barrier function due to aging and patients who underwent refractive surgery such as PRK (photorefractive keratectomy) or LASIK (laser in situ keratomileusis) or cataract surgery.

  • Publication number: 20110056763
    Abstract: An acoustic resonance device is installed in a compartment of a vehicle so as to reduce a low-frequency sound pressure (or noise) dependent upon a natural vibration. Specifically, an acoustic resonance device is a panel/diaphragm resonator, a resonance pipe, or a Helmholtz resonator, the inner space of which communicates with the compartment via an opening. The acoustic resonance device is positioned in proximity to an antinode of sound pressure owing to a natural vibration occurring in a driver/passenger space inside the compartment. Alternatively, the acoustic resonance device increases a particle velocity at a specific natural frequency or decreases sound pressure at an excitation frequency which occurs due to an external condition of the vehicle. The acoustic resonance device can be installed in a roof, a seat, a pillar supporting the roof, or a door of a vehicle.
