摘要： PURPOSE:To enable transfer even at the production of failure and to detect failed position, by transferring the position of failed line at a ring shift circuit to a spare position, even if one information line is in failure, through the provision of a spare line in addition to an information line on a common bus. CONSTITUTION:A spare line 1b is provided on a common bus 1 consisting of several information lines (e.g., 4 lines)1a. Normally, a bus receiver 4 receives information, signal lines 100-103 are transmitted to internal signal lines 500-503 respectively and transmitted to a logical circuit 8. Similarly, the information from the logical circuit is given to the information lines via internal signal lines 300-303 and signal lines 400-403. If one information line is in failure, this is detected at a bus failure detecting circuit, and the connection between the signal lines and the internal signal lines 300-304 is switched with ring shift circuits 6, 7 and it is transferred to a spare line 1b with a spare signal line 1b.

摘要： PROBLEM TO BE SOLVED: To provide an information distribution system and an information distribution method that can satisfy requirements of users by distributing information to a user terminal only when a free wireless resource exists thereby avoiding wireless traffic from being increased. SOLUTION: A free wireless resource discrimination section 11 discriminates whether or not a free wireless resource exists in each zone. When an information distribution section 13 acquires information of a zone where a free wireless resource exists from the free wireless resource discrimination section 11, the information distribution section 13 distributes information stored in an information database 12 to a user terminal 3 resident in the zone from which the free wireless resource is detected. Since the information distribution system 1 uses the free wireless resource to distribute the information provided from an information server 2 to the user terminal 3 in this way, the information distribution system can distribute information to user terminals without increasing wireless traffic.

摘要： PURPOSE:To realize the accurate diagnosis of an information processing system by reading the packing state of an information processor for each diagnosis start instruction to compare it with the packing information stored in a memory and diagnosing an information processor according to the information on said comparison. CONSTITUTION:The entire packing information on the information processors CPU 0 and 1 are read and stored in memories MM01-13 at the time of a system rise. Then the packing states of the information processors are read for each diagnosis start instruction and compared with those packing information stored in the memories MM0-13. When the coincidence is obtained from this comparison, the states of the information processors are diagnosed based on the stored packing information. While the packing discrepancy information is outputted when no coincidence is obtained from said comparison. Then the diagnosis is carried out based on a packing table as long as the packing states of the information processors are not changed in response to the answer given from a maintenance operator. While the packing table is replaced in case said packing states are changed. Then the diagnosis is carried out according to the replaced packing table. In such a way, all processors can be accurately diagnosed.

摘要： PURPOSE:To prevent insulating film breakdown by a method wherein a polycrystalline silicon film and metal film are formed on a semiconductor substrate and a diffusion layer opposite in conductivity to the semiconductor substrate, through the intermediary of an insulating film, and the diffusion layer is large enough to cover a polycrystalline silicon wiring, metal wiring, and polycrystalline silicon resistor. CONSTITUTION:A P-well 5 is formed on an N-type substrate 6 and thereon a fuse element.polycrystalline silicon resistor 2 is built with the intermediary of a silicon oxide film 4. Further, an Al electrode 1 is built through the intermediary of a silicon of a silicon oxide film 3 and a contact 7. In a circuit designed as such, with a diffusion layer lying just under a polycrystalline silicon resistor or a metal film through the intermediary of an insulating film, no short- circuiting occurs involving a substrate even in the presence of an insulating film breakdown because a short-circuiting occurs between the fuse element.polycrystalline silicon resistor and the diffusion layer isolated from the substrate by a junction. This realizes a fail-safe mechanism withstanding an interlayer insulating film breakdown.

摘要： PURPOSE:To eliminate intentional misoperation due to the unreturned state of key operation and accidental misoperation by making the operation of an operation console ineffective unless key operation is performed on the operation console for a certain time. CONSTITUTION:The counter of a key operation monitor circuit 20 counts with output pulses of an oscillation circuit 19. A program is so written that when key operation is effective, the key operation monitor circuit 20 is reset by a key operation monitor circuit reset line 106 through a general input/output interface circuit 18 every time key operation is performed. When 256sec are elapsed without any key operation in the key operation effective state, the key operation monitor circuit 20 overflows and sends out the 1st alarm signal 103. The program reads that out of the general input/output interface circuit 18 and resets the key operation effective state to invalidate subsequent key operation.
