  • Publication number: 20120010784
    Abstract: An occupant restraint device controller, including an electronic circuit substrate incorporating therein a control circuit that determines whether or not a vehicle has collided based on a detection output of a sensor detecting acceleration/deceleration of the vehicle and outputs a control signal for activating an occupant restraint tool. The electronic circuit substrate is accommodated inside a resin case provided with a structure for leading out a ground electrode from the inside to the outside of the resin case. The structure for leading out a ground electrode is configured such that a fixing leg, for fixing the electronic circuit substrate, is provided inside the case.

  • Publication number: 20120008026
    Abstract: A solid-state imaging device includes the following elements. A photoelectric conversion section is arranged in a semiconductor layer having a first surface through which light enters the photoelectric conversion section. A signal circuit section is arranged in a second surface of the semiconductor layer opposite to the first surface. The signal circuit section processes signal charge obtained by photoelectric conversion by the photoelectric conversion section. A reflective layer is arranged on the second surface of the semiconductor layer opposite to the first surface. The reflective layer reflects light transmitted through the photoelectric conversion section back thereto. The reflective layer is composed of a single tungsten layer or a laminate containing a tungsten layer.
