摘要： A combustion pressure sensor for an internal combustion engine is provided. The sensor includes a sensing element such as a piezoelectric device sensitive to a physical load applied thereto to produce an electric signal indicative thereof and a bendable member. The bendable member is bent upon application of the combustion pressure in the engine to apply the physical load to the sensing element. Specifically, the physical load is applied to the sensing element which arises from the bend deformation of the bendable member, thus eliminating the need for a complete surface-to-surface contact between the sensing element and the bendable member. This results in a decreased unit-to-unit variation in sensitivity of combustion pressure sensors and ensures the stability of output characteristics of the combustion pressure sensor.

摘要： A method of improving an output characteristic of an angular rate sensor including, for example, a fork oscillator and an improved structure of an angular rate sensor are provided. The improvement of the output characteristic is achieved by adjusting a physical structure of the oscillator to minimize unwanted vibrations of the oscillator or noises of a sensor output. The adjustment of the physical structure is achieved by trimming away an edge portion of the oscillator or a supporter for supporting the oscillator on a base.

摘要： An angular rate sensor is provided which measures the angular rate of a moving object such as an automotive vehicle. The angular rate sensor includes an installation base and an oscillator. The oscillator is excited to oscillate in a preselected direction perpendicular to an axis of rotation of the moving object and provides a signal indicative thereof. The installation base is used for installation of the sensor on the moving object and has an improved orientation structure for orienting the oscillator relative to the installation base during installation of the oscillator on the installation base so that the oscillator may oscillate in the preselected direction. The angular rate sensor is disposed within a casing through improved vibration isolators for absorbing unwanted vibrations impinging upon an operation of the sensor.
