IPC: H03G7/00
Filed: 1987-04-30
Abstract: PURPOSE:To prevent the sound quality deterioration at the time of quick increasing in an input signal amplitude by switching the time constant of an LPF of a detecting circuit to a short time constant in accordance with the output signal of the detecting circuit when the output value of a compressing circuit exceeds the dynamic range of the compressing circuit or a transmission line due to an overshooting phenomenon, etc. CONSTITUTION:A PCM signal inputted from an input terminal 1 is inputted to a dividing circuit 2, divided by the value outputted from a detecting circuit 3 and inputted to an output terminal 5 and an absolute value circuit 6. The signal made into the absolute value by the absolute value circuit 6 is inputted to an LPF 7 and a comparing detecting circuit 16. The comparing detecting circuit 16 compares the output value of the absolute value circuit 6 and the value of a constant 17, outputs the detecting signal whether or not the output value of the absolute value circuit 6 is larger than the value of the constant 17. A switching circuit 15 switches the time constant of the LPF 7 to a time constant I 13 or a time constant II 14 in accordance with the detecting signal from the comparing detecting circuit 16. The time constant I 13 is the time constant at the time of a usually operating and the time constant II 14 is the time constant shorter than the time constant I 13. Thus, the deterioration of a sound quality is prevented.

Filed: 1982-06-17
Abstract: PURPOSE:To monitor quantitatively a service state, by monitoring a transmitted radio wave, collating the monitored signal with the signal transmitted immediately before monitoring and delivering the error information to a monitoring device when dissidence is obtained from the above-mentioned collation. CONSTITUTION:A monitoring receiver 6 monitors the radio wave which is actually transmitted from a transmitter 4 and then transmits the radio wave to a paging signal transmission controller 3. The controller 3 collates the data to which the transmission has just been indicated with monitoring data. If no coincidence is obtained from the collation, this result of collation is transmitted to a monitoring device 7. Then the device 7 counts the number of errors and performs a level analysis for the grave faults, the ordinary faults, the attention needed, etc. to deliver an alarm. At the same time, the device 7 prints out the fault level, the fault data and the time and data when the fault is generated through a printer 8. Thus it is possible to monitor quantitatively the service state without requiring an artificial test.

Abstract: PURPOSE:To eliminate breakdown of the edge of a positive resist pattern even if temperature rises during etching step by forming a photoresist pattern formed with negative type photoresist on side surface as an etching mask. CONSTITUTION:An Si oxide film 2 is formed on an Si substrate 1, and an aluminum film 3 is subseqnently formed thereon. Thereafter a positive resist pattern 4 is formed thereon. Then, a negative resist 5 is coatedon the surface of the substrate 1.

At this time the resist 5 on the film 3 and on the pattern 4  is removed, but the part 5' of the resist 5 is retained on the side surface of the  pattern 4. Subsequently, with the pattern 4 as a mask the exposed aluminum is etched, thereby forming an aluminum pattern 6 in the approximately same width as  the pattern 4. Even if the temperature during the etching step rises higher than the  softening temperature of the positive resist, the edge of the positive resist pattern  may not break down.
