Patents by Inventor Yuichiro SUMIYOSHI

Yuichiro SUMIYOSHI 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).

  • Pressure sensor
    Patent number: 9506830
    Abstract: The invention prevents a pressure receiving space of a pressure sensor from being electrically charged. In a pressure sensor, a diaphragm is attached to a base which is fixed within a cover and a pressure receiving space in which an oil is sealed is formed. A semiconductor type pressure detecting device is connected to a plurality of terminal pins by a bonding wire. A neutralization plate attached to a periphery of the semiconductor type pressure detecting device or a part of the periphery thereof is connected to an earth terminal pin by an earth bonding wire, or is connected to the earth terminal pin by a soldering so as to prevent an insulative medium sealed within the pressure receiving space from being electrically charged.
