Patents by Inventor Shingo Jinno

Shingo Jinno has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Surface acoustic wave element, method of producing the same, and method of changing resonation frequency of the same
    Patent number: 8253302
    Abstract: A surface acoustic wave element includes a piezoelectric member, a comb-teeth electrode, and a reflector. The comb-teeth electrode is arranged on the piezoelectric member. The reflector is arranged on the piezoelectric member. The reflector reflects a surface acoustic wave transmitted from the comb-teeth electrode. The reflector has a plurality of areas, and each of the areas has a frequency to make a reflection efficiency the largest. At least two of the frequencies of the areas are made different from each other.
    Type: Grant

  • Angular velocity detection apparatus
    Patent number: 7898150
    Abstract: An angular velocity detection apparatus is disclosed. The angular velocity detection apparatus includes: a SAW angular velocity sensor; a synchronous detection unit configured to synchronously detect an output signal from the SAW angular velocity sensor by using a reference signal; and a switching signal generation unit. The switching signal generation unit cyclically switches on and off an input of a driving signal to the SAW angular velocity sensor, and switches on an input of the output signal to the synchronous detection unit when an unwanted wave is un-inputted to a sensing electrode of the SAW angular velocity sensor.
