    Abstract: A mounting device for a pressure sensor is disclosed. The mounting device comprises a cylinder head having a threaded hole for mounting a spark plug, a sensor housing orifice penetrating into a combustion chamber and a sensor pressure receiving section in the sensor housing orifice. A pressure sensor is mounted in the sensor housing orifice. The pressure sensor comprises a housing inserted into the sensor housing orifice and having a pressure receiving section for directly receiving the combustion pressure, and a piezoelectric device housed in the housing and producing a voltage corresponding to the combustion pressure received at the pressure received section. The device comprises a presser member pressing the pressure sensor toward the pressure receiving section by tightening of the spark plug. A vibration absorbing member is interposed between the presser member and the pressure sensor so as to absorb the vibration and the displacement transmitted from the presser member.

    Abstract: A simple and shock-resistant device to measure angular acceleration about a predefined axis without using any spinning or vibrating mass. The device comprises a weight having a shape symmetrical with respect to an axis which becomes the aforementioned predefined axis, a stress transducer such as a piezoelectric element which is attached to the weight so as to have sensitivity to shear stress in a circumferential direction about the aforementioned axis, and a base member to which the assembly of the weight and the transducer is fixed such that at least a major portion of the weight is spaced from the base member. For example, the weight is a generally circular metal plate and the transducer is a ring-shaped element of a piezoelectric ceramic material having electrode films on the annular surfaces.
