Abstract: PURPOSE: To prevent the blacking of a luminous tube by extending the end of an outside coil in the direction of coiling axle and by connecting the extended portion of the coil with a core wire to a metal sealing foil.  
     CONSTITUTION: The inside coil 5 of a tungsten wire is folded over and coiled to form the outside coil 6, and then the end 7 of the outside coil 6 is extended in the direction of coiling axle. Then, the wire core 8 is inserted into the coil, an electron- radiating substance is coated on the coil, and then a heat treatment is applied at a predetermined temperature to the coil. The extended portion of the outside coil 7 with the core 8 is welded to the metal sealing foil 9. Thus, the concentrating of arc spot on the damaged portion of coil is eliminated and therefore the early blacking of liminius tube can be prevented.

Title: Multi-processor system
Inventor: NAKANISHI KAZUO
IPC: G06F15/16
Filed: 1987-02-03
Abstract: PURPOSE:To prevent the total discontinuation of a multi-processor system by separating logically only a processor having a fault from the system CONSTITUTION:When a processor P has a fault among plural processors, a fault occurrence signal is delivered to a system state monitor signal line from the processor P. An optional processor monitoring the state of said signal line decides the occurrence of the fault with detection of the fault occurrence signal. A processor detecting means calls successively other processors to detect and specify a faulty one and gives the control commands to the faulty processor for stopping, resetting, interruption inhibiting actions, etc., based on the address signal of an address bus (a) and the data of a data bus (d). Thus the faulty processor stops the operation of a CPU, etc., resets each part and inhibits the interruptions supplied from an input/output control part, etc., based on the given control commands. Then the faulty processor is separated logically from a multi-processor system.

Abstract: PURPOSE:To realize a pseudo fault only by operating communication equipment being positioned at a nearest part geographically by setting the same address of the communication equipment at an upstream position by one than its own communication equipment on a transmission line as that of its own communication equipment. CONSTITUTION:The pseudo fault can be generated on a system by setting the same address as that of the communication equipment 1 on the communication equipment N being positioned at the upstream by one. At this time, when a transmission frame addressed to either another communication equipment is sent from the communication equipment 1, the communication equipment N deletes the frame without performing re-transmission judging it as a transmission frame transmitted from the transmission origin address of the transmission frame by its own even when the communication equipment whose address is designated receives the frames and performs the re-transmission to the transmission line after attaching reception confirming information, therefore, the communication equipment 1 judges that no transmission frame is returned due to the fault on the transmission line, and outputs the information of the fault to a processor 21.
