Patent JP-H10290287-A (JP)
Title: Telephone line-network repeating device
Inventor: HARUNA TAIZO
IPC: H04M3/00
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To eliminate malfunction caused by a signal which travels round by removing the frequency component of a busy tone by a filter from the signal outputted from a voice recording and reproducing circuit. SOLUTION: The band-pass filter 3 removes the frequency component of the busy tone to prevent the busy tone frequency component from traveling round from T to R of a hybrid transformer 4. Namely, if a telephone line side disconnects a held telephone call, the busy tone is inputted from the telephone line 8. This busy tone is sent to a special sound detecting circuit 6 through the hybrid transformer 4 and R. At this time, a holding tone is also put together with the traveling-round busy tone by the hybrid transformer 4. The band-pass filter 4, however, removes the frequency component of the busy tone from the holding tone to the line, so the special sound detecting circuit 6 can recognize the busy tone of the opposite party without misrecognizing it and a telephone line control circuit 9 indicates the disconnection of the line to a hooking circuit 5, so that the line is disconnected.

Filed: 1980-07-15
Abstract: PURPOSE: To make longer the life of a filter cloth, by dispersing a flow of dust-containing gas flowing into a hopper from an inlet nozzle, in order to distribute it to plural filter clothes by means of gas dispersion.  
     CONSTITUTION: Plural lattice shaped plates 7A, 7B are provided in a hopper 2 near a inlet nozzle 1. With these plates, dust-containing gas flowing into the hopper 2 from the nozzle 1 collides against the plates 7A, 7B, and reduces its velocity, leaving containing coarse particles settling into the bottom of the hopper 2, and flows into filter clothes 3 diluting its dust concentration. Then, a dust collecting load for each filter cloth of plural ones is equalized and reduced respectively. Besides, as the means of dispersing, different arrangements or different underside levels of filter- cloth strips can be used instead of using the plates 7A, 7B.
