摘要： A first component defines a threaded bore. A second component is kept in contact with the first component. A clamping screw penetrates through the second component and is screwed in the threaded bore. A lubricating agent film is interposed between the threaded bore and the clamping screw. The lubricating agent film is made of a macromolecular compound having a polar end group. The lubricating agent film serves to reduce the friction between the threaded bore and the clamping screw. Generation of dust is prevented when the clamping screw is being screwed into the threaded bore. In addition, the clamping screw exhibits a larger axial force at a certain amount of a fastening torque as compared with a conventional clamping screw. A larger axial force can thus be applied to hold the second component onto the first component.

摘要： An object of the invention is to prevent a communication error, which may occur as a JM signal or a CM signal is kept transmitted, thereby ensuring transmission and reception of desired data. When a communication apparatus, which has transmitted the JM signal, does not receive a CJ signal when a JM signal transmission time t3 elapses, the communication apparatus interrupts transmission of the JM signal and transmits a DIS with bit 6 set, and receives a CI, CJ, DCS or NSS to execute the protocol of Recommendation V.34 or T.30. When the communication apparatus, which has transmitted the CM signal, does not receive the JM signal when a CM signal transmission time t4 elapses, the communication apparatus interrupts transmission of the CM signal and transmits the CI signal, and receives an ANSam signal or a signal of a V.21 channel 2 to execute the protocol of Recommendation V.34 or T.30. When detecting the signal of the V.21 channel 2 within the CM signal transmission time t4, the communication apparatus interrupts transmission of the CM signal and receives the signal of the V.21 channel 2 to perform the protocol of Recommendation T.30.
