Title: Voice outputting watch
Inventor: NAKASHIMA AKIO
IPC: G04G13/00
Filed: 1981-02-06
Abstract: PURPOSE:To avoid the failure in hearing the voice output by generating an alarm sound whose acoustic pressure level is higher than the average acoustic pressure level of synthesized voice before and after the generation of the synthesized voice. CONSTITUTION:At the time of time reporting, the output phi1 is generated by an alarm synthesizing circuit 17 based on the output command from a control circuit 112, and the alarm is generated from an electroacoustic transducer 119. When an end signal is sent to the control circuit after the output phi1 is terminated, the voice output phi2 is generated by a voice synthesizing circuit 115 and a DA converter 116. When the voice output phi2 is terminated, the end signal is sent to the control circuit, and the output phi1 is again generated by the alarm synthesizing circuit 117 based on the alarm output command signal. Since the frequency of the alarm sound is approximately equal to the resonant frequency of the electroacoustic transducer 119, the acoustic pressure level of the alarm sound is larger than the average acoustic pressure level of the synthesized voice output.

Abstract: PURPOSE: To prevent the formation of aluminum hillocks on an aluminum wiring pattern and the occurrence of short circuits between metallic wires on the same layer. CONSTITUTION: After a first insulating film 2, aluminum film 3a, and silicon oxide film 4a are successively formed on a semiconductor substrate 1, wiring 3 and second insulating film 4 are formed by patterning the films 3a and 4a.
