Title: Inter-multispot voice communication terminal
Inventor: TOMITA YASUHIRO
IPC: H04L12/42
Filed: 1993-10-14
Abstract: PURPOSE:To eliminate the unpleasant feeling of users by stopping the output to a man-machine when the level of a subtracted voice signal is higher than that of an unsubtracted voice signal in terms of the voice of its own terminal. CONSTITUTION:A subtraction processing part 14 subtracts the voice signal (supplied in past) received from a delay processing part 21 from the voice signal received from a transducer 13 and then transmits the signal obtained from this subtraction to a voice decoding part 17, a level comparing part 50 and an addition processing part 15 respectively. The part 50 compares the voice signal received from the transcoder 13 with the voice signal received from the part 14 in terms of these signal levels. If the level of the latter signal is higher than the former one, the part 17 is instructed to stop transmission of signals to a voice output part 18. It is clear that the input voice signal is not normal if the level of the processed voice signal is higher than that of the unprocessed voice signal. Thus this abnormal signal is not transmitted to a man-machine and therefore no impact sound is produced from the man-machine.

Title: Vibrating actuator driving device
Inventor: FUKUDA TAIICHIRO
IPC: H02N2/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To make a stable and precise constant-speed control available even if the environment such as the temperature changes by providing a driving signal inputting section with an integration circuit which integrates an input signal and then outputs a voltage waveform and a switching circuit which switches the input signals for the integration circuit. SOLUTION: An integration circuit 15 integrates an input signal with a desired reference voltage Vc as a control initial value. The integration circuit 15 is so structured that the output Vo may monotonicly increase when the input is switched to Va by means of a switching circuit 16 and may monotonicly decrease when the input is switched to Vb, where Va=Vc-α, Vb=Vc+α (α>0). The upper and the lower limit of the driving frequency of a vibrating actuator 1 can be set by this method and thereby an unstable control can be prevented even near the resonance frequency without decreasing the efficency. Furthermore, a stable constant-speed control can be done even if the environment such as the temperature changes and thereby and a very precise constant-speed control is available.
