Abstract: PURPOSE: A damper of a vehicle driving shaft is provided to prevent changes of vibration frequency by the temperature change and a life span with a metal damper mass and a metal spring. CONSTITUTION: A driving shaft damper(1) is composed of a damper hub(10) combined with the outer periphery of a driving shaft; a damper mass(20) placed around the damper hub; and a metal spring(30) connected to the damper hub and the damper mass. The ring shaped damper hub is fixed in the driving shaft through a shaft hole(11), and the round damper mass is installed in the outer periphery. The metal spring made of plural iron coils connects the inner periphery of the damper mass to the inner periphery of the damper mass radially and elastically.

The analog fax(100) inputs the DIS, and outputs a DCS(Digital Command Signal) and a TCF(Training Check Frame) signal to the wire/wireless fax(400). The wire/wireless fax(400) inputs the DCS and the TCF signals, and outputs a CFR(Confirmation To Receive) signal to the analog fax(100). The analog fax(100) transmits fax data to a fax board(201) of a WLL(Wireless Local Loop) terminal(200). The fax board(201) temporarily stores the received fax data in an internal memory, and outputs the fax data to an IWF(Inter Working Function)(300) through an RF transceiver(202).

The process for calculating total sum of the thread performance time comprises the steps of reading the handles of successive threads starting from the system thread sequentially(S81,S82), comparing if the value is the same as the handle of the system thread(S83), and adding the performance time of the next thread until the same value is read(S84). The specific time interval for measuring the capacitance of a CPU corrects the previous capacitance and the current measured capacitance of a CPU with the average to reduce the sudden changes in capacitance if the interval value is small.
