  • Publication number: 20240117231
    Abstract: The pressure-sensitive adhesive layer forming organopolysiloxane composition of this disclosure is hydrosilylation reaction curable, wherein 1 mass % or more of a resin component is (b2) an organopolysiloxane resin having a weight average molecular weight (Mw) as measured in terms of standard polystyrene by GPC using toluene that is less than 4000, and the value obtained by dividing Tg+120(° C.) of the pressure-sensitive adhesive layer obtained by curing by Tg?+120(° C.) of the composition (pressure-sensitive adhesive layer), in which component (b2) is substituted by a resin with Mw 4000 or higher is less than 1.0. When used as a pressure-sensitive adhesive layer and when a specific resin component/polymer component ratio is selected to achieve a pressure-sensitive adhesive strength, the glass transition temperature (Tg) of the pressure-sensitive adhesive layer can be further reduced, resulting in a strong pressure-sensitive adhesive force and a low Tg at the same time.

    Abstract: A stretch detection system of a power transmission mechanism is connectable to a conveyor system including a motor, a rotation mechanism driven by the motor, and the power transmission mechanism driven by rotation of the rotation mechanism. The stretch detection system converts a signal of a current of the motor into a frequency domain signal, and calculates an integral value by performing integration on the frequency domain signal obtained by the frequency domain signal conversion unit, by using, as an integration range, at least one of regions of a sideband wave having a frequency determined using a rotation frequency of the rotation mechanism. A stretch diagnosis unit diagnoses a state of stretch of the power transmission mechanism by using the integral value calculated by the integral value calculation unit. Further, an output unit outputs a diagnosis result of the stretch diagnosis unit.
