Title: Electromagnetic air separator
Inventor: ITO HIDEMI
IPC: B03C1/00
Filed: 1994-04-27
Abstract: PURPOSE:To inexpensively, surely and safely separate air into oxygen, nitrogen and nitrogen ions by magnetically separating the air into oxygen and nitrogen and irradiating the nitrogen with UV to ionize the nitrogen. CONSTITUTION:This separator is fylfot shaped. Air is introduced from an air intake, the dust and moisture are removed by an air cleaner 1, and the cleaned air is introduced into a solenoid 4. The air is separated into the paramagnetic oxygen and diamagnetic nitrogen, and the nitrogen is moved to an S pole and oxygen to an N pole. The nitrogen is irradiated with a UV irradiator 9 and ionized while going to an S pole magnetic domain 11. The UV having irradiated the left half of the solenoid is reflected and passed through a polarized light circulating device 10 to irradiate N. The irradiated N enters the S pole magnetic domain 11. The N is discharged from an N discharge pipe 12, and N is sucked out with an N<+> suction pipe 13.

Title: Equipment fault detecting system
Inventor: AKAI FUMIHIRO
IPC: H04L1/22
Filed: 1992-05-20
Abstract: PURPOSE:To simplify a circuit configuration by providing a frame asynchronism detecting circuit and detecting an equipment fault. CONSTITUTION:When the deterioration in a transmission quality of an existing circuit is detected, a switching circuit 101 switches the existing circuit to a stand-by circuit. Subsequently, a clock synchronized with a clock of a selected signal is formed by a VCO 103, and a switching output 15 whose syncronism establishment is decided is outputted from a retiming circuit 104. On the other hand, the output of the circuit 104 at the time of non-establishment of sychronization of a signal frame of the stand-by circuit in which the VCO 103 comes not to be synchronized, or the output 15 is gone, an equipment fault signal 20 is generated from the frame asynchronous detecting circuit 105. By a constitution in which this asychnronous detecting circuit 105 of the VCO and an signal disconnection detecting circuit are unnecessary, the constitution of the equipment fault detecting circuit is simplified.
