  • Patent number: 8193631
    Abstract: A first interconnection is formed along a groove of a substrate and on a bottom surface of the groove, and has a first thickness. A second interconnection is electrically connected to the first interconnection and has a second thickness larger than the first thickness. An acceleration sensing unit is electrically connected to the second interconnection. A sealing unit has a portion opposed to the substrate with the first interconnection therebetween, and surrounds the second interconnection and the acceleration sensing unit on the substrate. A cap is arranged on the sealing unit to form a cavity on a region of the substrate surrounded by the sealing unit. Thereby, airtightness of the cavity can be ensured and also an electric resistance of the interconnection connected to the acceleration sensing unit can be reduced.

  • Publication number: 20100192402
    Abstract: To carry out drying of printing ink with the use of Nano sized high-temperature dryness steam. Nano sized high-temperature dryness steam being clustered on Nano oder is generated and jetted to the print side of printed material so that the Nano sized high-temperature dryness steam imparts intramolecular vibrational energy to ink of the print side. Consequently, the Nano sized high-temperature dryness steam being clustered on Nano oder not only passes through fiber pores in the printed material but also collides with the ink of the print side. The Nano sized high-temperature dryness steam having collided with the ink of the print side imparts thermally excited energy as intramolecular vibrational energy to the ink containing polar molecules. The ink is dried by the intramolecular energy.
