Title: Carrier frequency terminal fault report system
IPC: H04M3/08
Filed: 1992-03-13
Abstract: PURPOSE:To immediately cope with fault recovery and to prevent discrimination of an ineffective holding line at the time of periodical diagnostic operation by editing fault contents such as a fault occurrence position and a fault occurrence time and outputting them to a printer. CONSTITUTION:If a carrier frequency terminal equipment 13 is faulty, this fault is detected by a general incoming detecting circuit 10 and is reported to an analog leased line trunk 2. The analog leased line trunk 2 periodically reads this fault information by a provided program to recognize the circuit where the fault occurs at present. A carrier frequency terminal equipment fault information sending part 6 reports only this circuit to a local processor 4 which controls an electronic exchange 1. The local processor 4 edits fault information and outputs it to a printer 15 by a fault information output part 5.

Abstract: PURPOSE:To prevent the lowering of the quality of a thin-film consisting of Si, etc. by manufacturing the thin-film by irradiating a mixed gas containing a reaction gas such as SiH4 and mercury vapor with ultraviolet rays. CONSTITUTION:A glass substrate is heated, SiH4 gas is flowed, and an Si film is formed within the range of reaction-gas pressure of 0.1-100Torr by adjusting the flow rate of the gas and the displacement of a pump. Mercury atoms evaporating from a mercury vessel are made contain in a reaction atmosphere at that time. A glass pipe made of synthetic quartz increasing the transmittance of ultraviolet rays of 185nm is made contain in a lamp used. Consequently, the growth rate of the film takes a large value of approximately septuple as high as a value on the use of a lamp emitting ultraviolet rays only of 254nm at the same mercury-vessel temperature. The maximum value of the growth rate of the film is obtained at pressure close to approximately 1Torr of the gas, and a result better than the case only of 254nm can be acquired when a preferable gas pressure range extends over approximately 0.1-50Torr.
