An exhaust gas purification device (101, 102, 103) having a DPF (33) provided in an exhaust system (30) of an internal combustion engine. The device has one or more sound pressure measurement means (8F, 8R) for measuring exhaust sound pressure and calculation means (10) for calculating the amount of PM accumulation based on the exhaust sound pressure measured. On the upstream side of the DPF (33) are arranged exhaust gas temperature measurement means (36) and exhaust gas temperature raising means (34). The exhaust gas temperature raising means (34) is activated when the amount of PM accumulation calculated by the calculation means (10) is higher than a preset default and at the same time when the exhaust gas temperature measured by the exhaust temperature measurement means (36) is lower than a lower limit of a temperature region in which the DPF (33) can be regenerated.

A flywheel assembly that transmits torque from a crankshaft of an engine is provided. The flywheel assembly has a flywheel with a friction surface and an elastic coupling mechanism. The elastic coupling mechanism elastically couples the flywheel and the crankshaft in a rotating direction, and has a pair of first disk-shaped members axially spaced from each other and fixed together, a second disk-shaped member that is arranged between the pair of first disk-shaped members, and an elastic member that elastically couples the first disk-shaped members to the second disk-shaped member in the rotating direction. Further, a plate-like coupling portion extending between outer peripheries of the paired first disk-shaped members fixes the pair of first disk-shaped members together.

A method of manufacturing a crystal oscillator comprises: processing a crystal wafer, which has higher oscillation frequency inversely proportional to its thickness, into a thickness for a lower oscillation frequency than a reference oscillation frequency; measuring and storing the oscillation frequency of each area located lengthwise and crosswise of the crystal wafer, and subtracting the thickness of each area in turn depending on the difference in frequency of the oscillation frequency of each area and the reference oscillation frequency; and then obtaining a number of crystal pieces by dividing the crystal wafer into each area, wherein the crystal wafer is provided with dividing grooves in lengthwise and crosswise directions that section the crystal wafer into the individual areas. An object of the invention is to provide a method of manufacturing a crystal oscillator in which the thickness accuracy of each area of a crystal wafer is improved.

A flywheel assembly 1 is configured to transmit a torque from a crankshaft of an engine to an input shaft 6 of a transmission, and includes a flywheel 2 and a damper mechanism 3. The flywheel 2 receives torque from the crankshaft. The damper mechanism 3 includes a pair of disk shaped plates 11 and 12 fixed together and coupled to the flywheel 2, a hub 15 having a flange 20 arranged between the paired disk shaped plates 11 and 12 and transmitting a torque to the input shaft 6, and coil springs 16 and 17 that are compressed in a rotational direction when relative rotation occurs between the disk shaped plate pair 11 and 12 and the flange 20. A torsion angle stopper 30 is formed for stopping the relative rotation between the disk shaped plate pair 11 and 12 and the hub 15. This configuration serves to prevent application of an excessively large torque to the elastic member in the flywheel assembly.

In a plasma CVD apparatus, unnecessary discharge such as arc discharge is prevented, the amount of particles due to peeling of films attached to a reaction chamber is reduced, and the percentage of a time contributing to production in hours of operation of the apparatus is increased while enlargement of the apparatus and easy workability are maintained. The plasma CVD apparatus is configured such that in a conductive reaction chamber 104 with a power source 113, a vacuum exhausting means 118, and a reaction gas introduction pipe 114, plasma 115 is generated in a space surrounded by an electrode 111, a substrate holder 112, and an insulator 120.

Coil springs 33 and 36 couple input and output rotary members 2 and 3 together such that they can rotate relative to each other. The coil springs 33 and 36 have a torsion characteristic having a positive region and a negative region that has a lower rigidity than the positive region. A second friction generating section 71 is arranged such that friction is generated rotationally-between the input rotary member 2 and the output rotary member 3 due to the elastic force of the coil springs 33 and 36 when the two rotary members 2 and 3 rotate relative to each other. A friction suppressing mechanism secures rotational gaps 91 and 92 on only the negative side of the torsion characteristic. These rotational gaps serve to prevent the elastic force of the coil springs 33 and 36 from acting on the second friction generating section 71 within a prescribed angular range.
