  • Publication number: 20140240940
    Abstract: A connection structure for an electronic component, which is set on two lead frames spaced apart from each other. The electronic component is connected to the two lead frames by a conductive joining member. The connection structure includes two electrodes arranged on at least portions of a lower surface of the electronic component. The two electrodes respectively face the two lead frames. A receiving surface is included in each of the two lead frames immediately below the corresponding electrode. The receiving surface extends from a supporting portion supporting the electronic component toward the other one of the lead frames and away from the electronic component. The conductive joining member is located between the receiving surface of each of the two lead frames and the corresponding one of the electrodes.

  • Patent number: 7466119
    Abstract: A sensor circuit includes an AC component pickup circuit and first and second adder circuits or first and second high-pass filters, and specifies a range of normal voltages by an upper-limit voltage formed by adding an upper-limit threshold value to the AC component in the input voltage and by a lower-limit voltage formed by adding a lower-limit threshold value to the AC component in the input voltage. An abnormal offset voltage is detected by judging whether the output voltage of an inverting amplifier circuit is lying in the range of normal voltages.
