摘要： The invention provides a method of processing an inner surface of a bearing having a cylindrical shape which bearing includes a resin layer composed mainly of a synthetic resin as the inner surface, the method improving roughness of the inner surface and dimensional accuracy of an inner diameter of the bearing without cutting the inner surface. According to the method, the bearing is press-fitted into a jig and then the jig is mounted on a chuck. Next, a mandrel having a cylindrical bar shape is inserted into an inner diameter portion of the bearing and then the mandrel is heated by a heater up to 250° C., for example. The mandrel is expanded due to thermal expansion by the heating so that the inner surface, i.e., a surface of the resin layer is pressed by a press face of a peripheral surface of the mandrel.

摘要： A PLL circuit used in an apparat as for reading and writing data to a disk compensates for noise which causes a false clock signal or for missing clock signals which can be caused by a scratch or smudge on the surface of the disc. The PLL circuit includes a phase comparator for comparing a phase of a reference signal with a phase of a feedback signal and generates a phase difference signal. A charge pump receives the phase difference signal and generates an output signal, which is filtered by a low pass filter. The filtered signal is provided to a voltage controlled oscillator, which generates an oscillation output signal. A divider divides the oscillation output signal and generates the feedback signal. A time information generating circuit generates time information of the oscillation output signal, indicating the time period where it is presumed the reference signal is or should be received. A control circuit, using the time information, permits the output of the oscillation output signal when the reference signal is input during the presumed time period and maintains the output of the oscillation output signal when the reference signal is not received during the presumed time period.

摘要： A vibration damping material represents a high vibration damping property (loss factor .eta.) in a plurality of temperature ranges. A viscoelastic material layer between two constraining plates or between a constraining plate and a vibrating body is in the form of a bubble-contained adhesive layer containing bubbles. Near the glass transitional point (Tg), the bubble-contained adhesive layer is changed from a glass status to a rubber status and represents a first peak of the loss factor. In a temperature range above Tg, a second peak of the loss factor appears by virtue of consumption of vibration energy caused by friction at the interface between air bubbles and polymer attendant to expansion and contraction. That is, peaks of the loss factor appear at two temperatures, and the temperature dependency is decreased.

摘要： A gasket held between opposite flange joint surfaces with a bolt includes a combination of a complex material with a rubber material formed on one or both sides of a steel plate, the complex material having a convex or waveform bead, and a circular metal plate arranged at a bolt portion with a through-hole where a shank of the bolt penetrates and a bearing corresponding portion that corresponds to a bearing of the bolt around the through-hole. The gasket is configured to have the thickness (H3) of the bead provided to the complex material greater than the thickness (H2) of the circular metal plate that is equal to or greater than the thickness (H1) of the complex material. This structure provides a gasket indicating good sealing properties under such circumstances that a flange has low stiffness, a tightening load is reduced, and the distance between bolts is expanded.
