Abstract: A sensitivity switchable detection circuit includes a high gain circuit for outputting a first signal, a low gain circuit for outputting a second signal, and an output switching circuit for switching between the first signal and the second signal. When the first signal is smaller than a lower limit, the first signal determines a detected signal. When the second signal is larger than an upper limit, the second signal determines the detected signal. When the first signal is larger than the lower limit and the second signal is lower than the upper limit, a weighting function that uses the first signal and the second signal as input variables determines the detected signal.

Abstract: Disclosed is an acrylic sol for a sound insulating underbody coating. It includes acrylic polymer fine particles, a plasticizer, a filler, a plasticizer, a blocking type urethane resin, a curing agent and a foaming agent. Since it includes the acrylic polymer particles as a major constituent unit, it does not generate a hydrogen chloride gas and dioxins when it is burned. Moreover, since the paint film resulting from the acrylic sol has a net-shaped structure by the cross-linkage reactions of the urethane resin, and since the bulkiness of the paint film is increased by the foaming agent, it has a good cold resistance and adhesion property toward automotive steel plates, and effects a superb chipping resistance and sound insulating performance.
