  • Patent number: 9209780
    Abstract: A piezoelectric oscillator includes a piezoelectric vibrating piece, an integrated circuit, and a package. The package includes a first layer, a second layer, a third layer, and a fourth layer. The ceiling surface as a portion of the inferior surface of the third layer has a rectangular shape surrounded by short sides and long sides. The ceiling surface includes a pair of frequency checking terminals electrically connected to the connecting electrodes and control terminals to control the integrated circuit. The pair of the frequency checking terminal are adjacent to one another. The respective frequency checking terminals are disposed in contact with any of the long sides and one of the short sides. The control terminals are extracted to the top surface of the third layer, and overlap the frequency checking terminals in a vertical direction on the top surface of the third layer to be connected to the mounting terminals.

  • Patent number: 9154076
    Abstract: A dual-mode crystal oscillator includes a single AT-cut quartz crystal piece, a package, and an integrated circuit. The integrated circuit includes an oscillation circuit configured to cause the AT-cut quartz crystal piece to oscillate at a frequency in the MHz band, a dividing circuit configured to divide the frequency in the MHz band to generate a frequency of 32.768 kHz, a selection circuit configured to select one of a pause state where the frequency in the MHz band is not output and an active state where the frequency in the MHz band is output. The mounting surface includes three electrodes arranged in a direction along the long side and two electrodes arranged in a direction along the short side. The electrode to output the frequency of 32.768 kHz and the electrode to output the frequency in the MHz band are arranged not adjacent to one another.

  • Publication number: 20130337476
    Abstract: Disclosed herein is a method for the detection or preliminary screening of coronary artery disease, including: obtaining a urine sample from a human subject suspected of having coronary artery disease; detecting a level of sCD14 in the urine sample from the human subject suspected of having coronary artery disease; and comparing the detected level of sCD14 in the urine sample with a predetermined standard, wherein the level of sCD14 in the urine sample from the human subject suspected of having coronary artery disease greater than the predetermined standard is indicative of the presence of coronary artery disease.
