An object of the invention is to suppress an increase in an inner diameter of a friction facing of a clutch disk assembly, which may be caused by fixing portions of a plate member pair of a clutch disk assembly 1. The clutch disk assembly 1 is provided to couple to a flywheel 2 of an engine. The clutch disk assembly 1 includes a friction facing 20, a pair of plates 15 and 16, a hub 8, and coil springs 11. The plates 15 and 16 have fixing portions 34 fixing their outer peripheral portions together. The coil springs elastically couple the paired plates 15 and 16 to the hub 8 in the rotating direction. The fixing portions 34 project radially outward beyond the inner periphery of the friction facing 20.

A damper mechanism is provided to achieve preferable vibration damping performances by providing different characteristics on positive and negative sides of torsion characteristics. In a damper mechanism of a clutch disk assembly 1, a plurality of coil springs 33 and 36 are arranged so that they are compressed when plates 12 and 13 rotate relatively to a hub 6 such that a higher torsional rigidity occurs on the positive side of the torsional angle range than the negative side. A friction generating mechanism 69 is arranged to generate friction when the plates 12 and 13 rotate relatively to the hub 6. The friction generating mechanism 69 generates a larger friction on the positive side of the torsion angle range than the negative side.

There is provided a crystal oscillator in which a crystal blank and an integrated circuit (IC) chip are accommodated in a vessel and the IC chip is fixed through a bump to the bottom surface of the vessel by means of ultrasonic thermocompression bonding. The IC chip contains an oscillation circuit utilizing the crystal blank and has a plurality of terminal electrodes on a major surface thereof. A plurality of connection terminal portions are formed on the bottom surface of the concave portion of the vessel so that each of the connection terminal portions corresponds to one of the terminal electrodes. Each of the connection terminal portions is formed into a rectangular shape and the width of each connection terminal portion is identical. The terminal electrodes and the connection terminal portions are bonded to each other through a bump by means of ultrasonic thermocompression bonding. Thus, the IC chip is fixed to the bottom surface of the concave portion of the vessel.

A pair of spring seats (32) are used at opposite ends of a small coil spring (6) disposed between a power input rotary member and a power output rotary member. Each spring seat (32) includes a receiving side surface for receiving the spring and a contacting surface (36). Each contacting surface (36) is formed with four slanting surfaces that slant inward toward a central portion of the contacting surface. The intersections of the four slanting surfaces of each spring seat define two intersecting V-shaped grooves (37, 38). The power input rotary member and the power output rotary member contact respective portions of one of the V-shaped grooves (37, 38) of each spring seat. Engagement between the rotary members and the engaged V-shaped grooves restricts movement of the spring seats (32).

In one embodiment, a pair of spring seats (32) are intended for use at opposite ends of a small coil spring (6) disposed between a power input rotary member and a power output rotary member. Each spring seat (32) includes a receiving side surface for receiving a respective end of the small coil spring and a contacting surface (36). The contacting surface (36) is formed with slanting portions (37, 38) with V-shaped cross section, mutually perpendicular to one another. The power input rotary member and the power output rotary member contact a respective slanting section of one of the slanting portions (37, 38). In another embodiment, a spring seat (40) is provided with a first support portion (43) and a second support portion (44) such that the orientation of the spring seat (40) determines a phase or orientation of the power input rotary member with respect to the power output rotary member. In a third embodiment, a friction element is formed of resin and includes a friction adjusting element (20). The body portion (15a) of the friction element is made of resin and includes a friction generating surface contactable to the side surface of a sub-plate (5). The fiction adjusting element (20) is provided in the friction generating surface of the body portion (15a) by molding and is intended for modifying the friction coefficient thereof.

In an annular clutch release cylinder assembly comprising an annular piston and a cylinder housing formed by nesting a pair of cylinder members, each comprising a tubular portion and a radial flange, with each other. The annular piston is guided and reinforced by the cylindrical extension of one of the cylinder members so that the annular piston is made highly rigid against bending deformation. Therefore, the annular piston can be made of plastic material so that the weight and the fabrication cost of the release cylinder assembly may be reduced. By placing the flanges of the cylinder members directly one over the other, and forming at least a part of the passage leading to the annular slot by forming a recess in one of the flanges of the cylinder members, it is possible to reduce the axial dimension of the clutch release cylinder assembly.

The clutch cover assembly comprises a clutch cover, a pressure plate, a washer-type spring and a lever member. The clutch cover is fixed to a flywheel. The pressure plate is located within said clutch cover and is fashioned with a pressing surface for clamping facings against the flywheel. The washer-type spring engages the pressure plate to the flywheel. The lever member, supported by the clutch cover, is for engaging the pressure plate in combination with the washer-type spring to the flywheel and for releasing engaging loads of the washer-type spring from the pressure plate.

To accomplish a superior characteristic for absorbing and damping torsional vibrations in a damper disk assembly and a flywheel assembly. A damper disk assembly includes a pair of plates 11 and 12, a flange 20, coil springs 16 and 17, and friction plates 58 and 59. The pair of plates 11 and 12 is fixed to each other. The flange 20 is disposed between the pair of plates 11 and 12 in the axial direction. The coil springs 16 and 17 elastically couple the pair of plates 11, 12 and flange 20 in the rotational direction. The friction plates 58 and 59 are disposed to operate in parallel with the coil springs 16 and 17 between the pair of plates 11, 12 and the flange 20 in the rotational direction, frictionally engage with the pair of plates 11 and 12, and engage with the flange 20 to be relatively rotatable in only range of the small torsional angle.

An exhaust gas purification device having a DPF provided in an exhaust system of an internal combustion engine. The device has one or more sound pressure measurement means for measuring exhaust sound pressure and calculation means for calculating the amount of PM accumulation based on the exhaust sound pressure measured. On the upstream side of the DPF are arranged exhaust gas temperature measurement means and exhaust gas temperature raising means. The exhaust gas temperature raising means is activated when the amount of PM accumulation calculated by the calculation means is higher than a preset default and at the same time when the exhaust gas temperature measured by the exhaust temperature measurement means is lower than a lower limit of a temperature region in which the DPF can be regenerated.
