Title: Telephone device
Inventor: WASHI TEPPEI
IPC: G10L21/043
Filed: 2011-01-21
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of echo caused by reverberant sound.SOLUTION: After a predetermined delay time τ(=t2-t1) elapses from a time point (t=t1) at which call transmission is finished, a voice switch 3 switches the call state from a call transmission state to a neutral state. Therefore, a calling speed converter 11 does not execute calling speed conversion for the period from t=t1 to t=t2, and thus echo B input to the calling speed converter 11 is directly input to the voice switch 3 without being decelerated. As a result, the echo B has already extinguished at the time point (t=t2) at which the voice switch 3 is switched from the call transmission state to the neutral state, that is, at the time point at which the calling speed converter 11 starts the calling speed conversion. Therefore, the voice switch 3 is not switched to a call receiving state even when the calling speed converter 11 executes the calling speed conversion, and no echo sound is emitted from a speaker 2.

Abstract: PROBLEM TO BE SOLVED: To improve analysis accuracy by reducing undesired periodic level fluctuation appeared in signal strength data, when a small amplitude AC voltage is impressed on a rod electrode in order to compensate a non-ideal state of a quadrupole electric field which is caused by displacement of the rod electrode.SOLUTION: A common reference clock signal CLK generated in a common clock signal generating part 15 is sent to an A/D control signal generating part 16 and a high frequency voltage generating part 12.
