  • Patent number: 10330552
    Abstract: In aspects of the invention, a sensor unit is stored in a recessed sensor mount portion formed in a resin case. The sensor unit can be formed so that a semiconductor pressure sensor chip is joined to one side of a glass pedestal, and the other side of the glass pedestal is die-bonded to the bottom of the sensor mount portion through an adhesive. An electrode pad on the semiconductor pressure sensor chip is electrically connected through a bonding wire to a lead terminal for leading externally that pierces through the resin case and is integrally insert-molded therein. An entire surface of the sensor unit, an exposed part of the lead terminal internally-located in the resin case, the bonding wire, and an exposed part of an inner wall of the resin case can be coated with the protective film composed of a poly(p-xylylene)-family polymer including fluorine.

  • Patent number: 10126145
    Abstract: An analog signal is supplied to a first conversion section of a physical quantity sensor device, converted to digital, and set to be an initial output value of the first conversion section. Adjustment information for the first conversion section is calculated based on the error between the initial output value and a target output value of the first conversion section. Before an initial output value of a physical quantity sensor is measured for calculating initial setting information of a physical quantity sensor device, the first conversion section is adjusted based on the adjustment information. Also, a digital signal is supplied to a second conversion section of the physical quantity sensor device, converted to analog, and set to be an initial output value of the second conversion section. The second conversion section is adjusted based on adjustment information for the second conversion section.

  • Patent number: 9857782
    Abstract: A first acquiring unit acquires initial output values of a physical quantity sensor. A second acquiring unit acquires target output values for the physical quantity sensor. A first calculating unit extracts first characteristic values by calculating a second-order first characteristics formula which indicates corrected output characteristics of the physical quantity sensor, based on the initial output values and target output values of the physical quantity sensor. The second calculating unit extracts second characteristic values by calculating a second-order second characteristics formula for correcting the first characteristic values, based on a predetermined temperature and the first characteristic values. A computing unit computes a corrected output value for the physical quantity sensor based on the first characteristics formula which is corrected by inputting the second characteristic values to the second characteristics formula.

  • Patent number: 8237505
    Abstract: This invention provides a low-current consumption type signal amplification circuit, which limits the output voltage to fix a lower-limit (upper-limit) saturation voltage of the amplification circuit at a predetermined lower-limit (upper-limit) limiting voltage. The signal amplification circuit comprises a negative feedback amplification circuit, a lower-limit voltage limiting circuit and an upper-limit voltage limiting circuit. The lower-limit voltage limiting circuit increases a resistance between an output terminal of the negative feedback amplification circuit and a ground terminal when the output voltage of the negative feedback amplification circuit falls below the lower-limit limiting voltage. The upper-limit voltage limiting circuit increases a resistance between the output terminal of the negative feedback amplification circuit and a high-potential side of a power supply when the output voltage of the negative feedback amplification circuit rises above the upper-limit limiting voltage.
