A vibrator is disclosed having a vibrating body with a polygonal lateral cross-section. Two piezoelectric elements are disposed on nonparallel side surfaces of the vibrating body. A support structure is provided which supports the vibrating body at two support points of the vibrating body. The support points are located in a split plane which passes through the line of intersection of the two planes in which the two side surfaces lie and bisects the inner angle formed by these two planes. Furthe...

A piezoelectric electro-acoustic transducer eliminates a negative influence caused by metal terminals upon the sound pressure and resonant frequency characteristics even when size and thickness reduction of the transducer are made. The transducer includes a piezoelectric diaphragm which includes a piezoelectric ceramic plate and a metal plate stored in a casing. The transducer also includes metal terminals in contact with the piezoelectric diaphragm and extending to the outside of the casing. Th...

Disclosed herein is a piezoelectric resonator (11) utilizing a width expansion mode provided with a piezoelectric resonance part (12) having a rectangular section in which a ratio b/a of the length of each longer side to that of each shorter side is within a range of .+-.10% about the following value: where a represents the length of each shorter side, b represents that of each longer side, .sigma. represents a Poisson's ratio and n represents an integer, and support members (16, 17) which are c...

In a piezoelectric vibrator capable of vibrating under an expansion mode of vibration, which has a piezoelectric vibrating element including a generally rectangular vibrateable substrate, made of a metallic material having a constant modulus of elasticity.

The wi...

The specification discloses a connecting device comprising an elastic deformable ring and a barrel nut adapted to connect a tubular cylindrical member to a second cylindrical member, the tightening of the barrel nut causing the compression of the ring mounted on a receiving throat of the second member and extending into a blind bore formed on the inner surface of the tubular member, the barrel nut being in free slidable and rotatable relationship with the second member.

A spigot is inserted into a socket, with a seal packing pressed from the opening side of the socket into an annular space defined between the socket and the spigot, a lock ring fitted in an annular groove formed in the inner peripheral surface of the pocket inwardly of the seal packing, and an engaging projection provided on the outer periphery of the front end of the spigot for axial engagement with the lock ring. The lock ring is a split lock ring which can be inserted from the annular space b...

A method and a device for operating an internal combustion engine improve the response of the internal combustion engine and increase its torque. An exhaust valve of the combustion chamber of the internal combustion engine is opened during a discharge phase of the internal combustion engine for discharging exhaust gas, generated via combustion, from a combustion chamber into an exhaust system of the internal combustion engine. The exhaust valve is closed again and re-opened during this discharge...

An E8-VSB reception system system is provided. A VSB receiver converts a received broadcast signal into a digital baseband signal in synchronization with a first symbol clock, converts a decision signal synchronized with a second symbol clock into a decision signal synchronized with the first symbol clock, performs channel equalizing and noise removal on the digital baseband signal using the converted decision signal, performs error correction on the noise removed signal, and outputs error-corre...
