Title: Channel connection test system for 4-wire exchange
Inventor: NISHIMURA YOSHIROU
IPC: H04M3/24
Filed: 1978-03-28
Abstract: PURPOSE:To enable the detection for the channel fault which cannot be detected through the pilot test by giving the unmatching state temporarily to the impedance  of the 2-wire/4-wire converter circuit. CONSTITUTION:The ring back tone is always sent back to the calling subscriber from the called subscriber storage exchange while the called subscriber is being called. With this ring back tone, impedance alteration circuit IMP is controlled through control unit CONT within the range of service standard to the calling subscriber, and thus the balance of hybrid HYB is put under the unmatched state temporarily. In this way, the presence or absence of the reflected signal is confirmed via voltage detecting circuit DET connected to the 4-wire side output of HYB to carry out the connection test. In this case, circuit IMP is released immediately after confirmation of the reflected output of the ring back, and the normal impedance matching state is recovered. Thus, the HYB oscillation caused by the answer of the called subscriber can be prevented.

IPC: H03F3/34
Filed: 1979-03-28
Abstract: PURPOSE:To realize a high-gain inverse amplifier by forming the load resistance with the capacitor and the MOS switch. CONSTITUTION:The load comprising capacitor C1 plus switching transistors Q6 and Q7 of enhancement-type nMOSFET is connected in series to driving transistor Q5 of the enhancement-type nMOSFET. Thus the inverse amplifier is obtained. Then the clock pulses featuring the phases different by 180 deg. from each other are applied to the gates of FETQ6 and FETQ7 each. As a result, capacitor C1 repeates the charging and discharging, and the discharge current flows through FETQ5. accordingly, this circuit becomes equal to the circuit which features the load resistance of resistance value 1/(C1Xf), where f means the frequency of the clock pulse. Therefore, the voltage gain is adversely proportional to the capacity of frequency f and C1. In this connection, the high-gain circuit can be formed in a simple way via the MOS and with selection of the capacitor.

The difference between the peak value of a high-speed electric signal transmission line 4 and the GND level is inputted from the circuit 8 to the positive input of the operational amplifier 9a of a current sucking out circuit 9. A negative power source voltage is applied via a resistor 9b to the negative input of the amplifier 9a.

As a result, the flowing of the photocurrent into a terminal resistor 3 is prevented.

A high-melting point metal silicide film 7 is formed on the whole surface of the step; a polysilicon film 4 is etched and removed while the high-melting point metal silicide film 7 remaining on sidewalls of the step by etching the whole surface is used as a mask. Since the wiring layer of a two-layer structure by the polysilicon film 4 and the high-melting point metal silicide film 7 is formed, the wiring layer whose line width is the film thickness of the thin high-melting point metal silicide film 7 remaining on the sidewalls of the step is formed between it and the semiconductor substrate 1 via the poly-silicon film 4. Thereby, it is possible to form the stable wiring layer whose close-contact property is good.
