Title: Dtmf signal reception system
Inventor: HIROSE NORIMASA
IPC: H04M1/65
Filed: 1988-12-26
Abstract: PURPOSE:To recognize a pushphone signal accurately by stopping the transmis sion of a voice message for a prescribed time when a frequency component of a DTMF signal is detected during the transmission of a voice message, detecting the presence of the frequency component of the DTMF signal again, and discriminating the incoming of the DTMF signal. CONSTITUTION:While a voice message is sent from a telephone terminal equip ment, when a pushbutton(PB) detector 26 detects the frequency component of a pushphone signal (DTMF signal), the transmission of the voice message from a voice message transmission/reception circuit 17 for a prescribed time is stopped. Then the presence of the frequency component of the DTMF signal is detected in this state and it is discriminated that the DTMF signal comes from the telephone line only in the presence to apply reception processing. Thus, the voice message during transmission and a pushphone signal from the line are distinguished clearly, and misreception of the pushphone signal and malfunction is prevented.

The segregation of P at the crystal grain boundary of the steel sheet is suppressed by cooling this sheet at ≥100°C/sec average cooling rate down to at least 300°C and thereafter, the sheet is held without annealing or is annealed for 5secW15min at 580W1,000°C. This steel sheet is cold rolled to form the steel sheet having the final sheet thickness, following which the steel sheet is annealed for 5secW15min at 700W900°C.
