|20150226641||COMBUSTION PRESSURE SENSOR - A combustion pressure sensor is formed of a ring-shaped cylindrical body. The combustion pressure sensor detects combustion pressure in a combustion chamber of an engine by being attached to an outer periphery of a tip of a functional component attached to the combustion chamber. The cylindrical body forms sealed space sealed with a ring-shaped diaphragm on one side and with a ring-shaped support member on an opposite side. The sealed space is defined by an external cylindrical member and an internal cylindrical member coaxial with each other. The diaphragm has a ring-shaped pressure receiving part formed on a side near the combustion chamber to receive pressure from outside and a ring-shaped transmitting part formed on a rear surface of the diaphragm. A pressure transmitting member and a pressure detecting element are provided in the sealed space. Tight abutting contact is formed between the transmitting part of the diaphragm and the pressure transmitting member, between the pressure transmitting member and the pressure detecting element, and between the pressure detecting element and the support member.||08-13-2015|

|20100102671||PIEZOELECTRIC DEVICE - A piezoelectric device, having a piezoelectric vibrating piece and a circuit element being electrically connected, is provided with a package for storing inside at least the piezoelectric vibrating piece of the piezoelectric device. The package is made up of a substrate and a cover body, and on the outer surface of the package, an electrode terminal electrically connected to at least the circuit element or the piezoelectric vibrating piece is provided. The electrode terminal includes an external connecting terminal which is electrically connected with an external circuit board and an input-output terminal which is electrically non-connected with the external circuit board, at the time of mounting the package on the external circuit board. The surface of the external connecting terminal and that of the input-output terminal are formed of materials different from each other so that adhesive characteristics to a mounting material such as a solder are varied. Thus, at the time of mounting the piezoelectric device on the external circuit board by using the mounting material such as the solder, short-circuit between the input-output terminal and the external connecting terminal is eliminated, and a highly reliable piezoelectric device is provided, having stable circuit operation without inducing characteristic deterioration.||04-29-2010|
