  • Safety device for an automobile vehicle
    Patent number: 5402343
    Abstract: A safety device for an automobile vehicle includes a first integration circuit for integrating an output value generated from a G sensor and a decision circuit for comparing the integrated value with a predetermined decision level to determine whether the safety device should be activated. In the first integration circuit, a previously integrated value is incrementally reduced to provide a current integrated value.

  • Acetal resin composition
    Patent number: 4578422
    Abstract: This invention relates to a glass-reinforced acetal resin composition having excellent heat stability and mechanical strength. The resin composition contains both a polycyanate compound and an amino-substituted triazine and/or a cyanoguanidine compound as coupling agents. The resin composition of the invention is useful, for example, as a material for automotive parts and machine parts because of its higher mechanical strength and heat stability, especially the former, than conventional known glass-reinforced acetal resins.
