摘要： An apparatus for reducing periodical noises transmitted from a noise source into a vehicle passenger compartment. The apparatus comprises control sound sources for producing control sounds in the vehicle passenger compartment, residual noise sensors for detecting the residual noises in the vehicle passenger compartment, transfer function filters modeled on transfer function between the control sound sources and the residual noise sensors, and adaptive digital filters having variable filter coefficients. A reference signal is produced in the form of a series of impulses having the same period as the noises. The transfer function filters are convoluted with the reference signal to produce reference processed signals. The adaptive digital filters are convoluted with the reference signal to generate drive signals to drive the control sound sources. The filter coefficients of the respective adaptive digital filters are updated based on the processed reference signals and the residual noises to reduce the noises in the vehicle passenger compartment.

摘要： Out of combinations of three pins(15) and bushes(16a-16c), a clearance between one of the bushes(16a) and the pin(15) is small, and a clearance between the other two bushes(16b,16c) and the pins(15) are large, whereby torque transmission is always performed by only one pin(15) and the bush(16a) during rotation to avoid a transfer phenomenon between the pins. Disposing the pins and the bushes at an equal interval allows a good balance of rotation to provide an easy assembly.

摘要： A vibration reducing system of an internal combustion engine for an automotive vehicle. The vibration reducing system comprises a roll vibration system which generates a roll vibration of an engine main body, the roll vibration having a first vibration mode. Additionally, a rotational vibration system is provided to generate a rotational vibration having a second vibration mode, and includes a crankshaft of the engine, for generating a rotational driving force, a main flywheel fixedly connected to the crankshaft, a driving force transmitting mechanism through which the rotational driving force of the crankshaft is transmitted, the driving force transmitting mechanism being movably secured to the engine main body, and an inertial mass member drivably connected to the driving force transmitting mechanism and rotatable to generate an inertial force upon receiving the rotational driving force transmitted through the driving force transmitting mechanism. In the vibration reducing system, the first and second vibration modes cause antiresonance at an antiresonance frequency. Additionally, the rotational vibration system is adjusted to cause the antiresonance frequency to be generally coincident with one of frequencies which are obtained respectively by multiplying an engine-revolutional frequency at a predetermined engine speed by values each being represented by (a natural number/2).
