摘要： A glow plug with combustion pressure sensor is disclosed having a cover and a housing with which a piezoelectric element is hermetically accommodated. A lead wire having flexibility is employed to supply electric power to a heating member. The lead wire, fixedly connected to the heating member, extends through an insertion bore of the cover and is hermetically bonded to an inner circumferential wall of the insertion bore. When the heating member is axially displaced upon receipt of a combustion pressure, the lead wire flexes to absorb the resulting displacement, causing a joint portion between the cover and the lead wire to have no drag against the displacement. This allows the piezoelectric element to detect the combustion pressure with high precision.

摘要： A combustion pressure sensor for detecting a combustion pressure in a combustion chamber of an engine is disclosed as having a housing mounted to an engine head in a gastight structure, a pressure sensor carried on the housing at a base end portion thereof, a transfer member having a pressure-receiving portion exposed to the combustion chamber to be axially slidable in the housing to transfer a combustion pressure from the combustion chamber to the pressure sensor, and a seal member disposed between the pressure-receiving portion of the transfer member and the housing in a gastight sealing structure to block an intrusion of combustion gas from the combustion chamber into the housing. The seal member includes a flexible portion with low rigidity that can stretch and absorb load acting on the pressure sensor when mounting the housing onto an engine cylinder.

摘要： A combustion pressure sensor has a cylindrical housing having a fixing functional member fixed to an engines head, and a sealing functional member disposed on the inner side of the fixing member, a transmission member disposed on the inner side of the sealing member through an opening to face a combustion chamber and to be movable along the axial direction, a detecting unit disposed between the sealing member and the transmission member to detect a combustion pressure in the combustion chamber in response to the movement of the transmission member, and a seal member for shielding the opening from the combustion chamber. The members are connected with each other at a connection area such that extension and contraction in the axial direction in each of the functional members is independent of the other one.

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.
