IPC: B25B23/14
Filed: 2002-06-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a screw tightening method that can stably control axial force.  <P>SOLUTION: The screw tightening method comprises the steps of calculating a torque gradient (dT/dθ)<SB>i</SB>from measured data (the newest point n) of tightening torque T and a tightening angle θ and judging whether the torque gradient is stabled or not, determining a point where the torque gradient in a stable area crosses with an angle axis in a torque diagram as a temporary tightening start angle θ<SB>si</SB>and calculating an averaged true tightening start angle θ<SB>s</SB>in an overall stable area of the torque gradient if the torque gradient is stabled, and obtaining a tightening finish angle θ<SB>E</SB>from the tightening start angle θ<SB>s</SB>and finish tightening when the present tightening start angle θ<SB>i</SB>reaches the tightening finish angle θ<SB>E</SB>. As this method obtains the tightening start angle θ<SB>s</SB>from the stable area of the torque gradient, it can minimize the axial force variation.  <P>COPYRIGHT: (C)2004,JPO

IPC: H04B1/04
Filed: 2002-06-20
Abstract: <P>PROBLEM TO BE SOLVED: To solve a big problem that a voltage drop across an FET and a deterioration in efficiency are caused while a very large current flows because the EFT is inserted between the power source and power amplifier in a conventional practice.  <P>SOLUTION: A control circuit 15 controls an amplification factor (gain) of an amplifier 12. The control circuit 15 controls a power amplification factor of a device 13. The control circuit 15 controls the amplifier 12 to have a maximum gain in advance and to allow a current to flow therethrough before start of transmission, and increases the gain of the device 13 just after start of transmission and gradually decreases the gain of the amplifier 12 at the same time. Thus, the gradient of the sum of consumed currents by the amplifier 12 and the device 13 at start of transmission is smaller than that of the case with the device 13 that is singly operated and a temporal change in rush current when viewed from a power supply 14 can be decreased. Thus, the effect of a path from the power supply 14 to the device 13 imposed on others can be decreased and a stable operation of an apparatus adopting the transmission circuit can be expected.  <P>COPYRIGHT: (C)2004,JPO
