Abstract: PURPOSE:To facilitate a retrieval as a time lapse VTR system by storing plural signals in one magnetic tape switchingly, and selecting and reproducing one video signal monitored from the tape. CONSTITUTION:Recorded video signals are read out by a magnetic head 16, and reproduced by a reproduction circuit 19 as such video signals that the outputs of four pieces of image pickup parts 10 are circulately switched in the unit of frame.

Abstract: PURPOSE:To make it possible to change breakdown voltage readily, by forming diffused layers at two places of a P-type Si substrate, and forming a first polysilicon layer on the diffused layers through insulating films having different thicknesses. CONSTITUTION:The outer part of the N<+> diffusion of a P-N junction diode is covered with first and second polysilicon layers 8 and 9. A silicon oxide film 10 is formed between a P-type Si substrate 5 and the first PS 8. A silicon oxide film 11 is formed between the first PS 8 and the second PS 9. At the time of operation, a positive voltage V0 is applied to the second PS 9. A potential V2 of the substrate 5 is grounded, and a potential V1 of an N+ diffused layer 6 d s increased. When the potential V1 reaches a certain value, breakdown occurs. Since the positive voltage is applied to the electrode of the second PS 9, however, a positive potential is also applied to the first PS 8 through capacitor coupling and a lower depletion layer is affected. The breakdown voltage of the diode due to the P-type Si substrate and the N<+> diffused layer 6 becomes the value higher than a conventional P-N diode.

The packet 100 from the protocol processor 21 is transferred through the bus 29, repeater line storage device 23 and route RT13 to a packet switch PS3. The packet switchboard PS3 transmits the packet 100 to the preset terminal. Based on the measured call amount transferred from a bus 28 for control, centralized control equipment 16 calculates a route use rate.  At the time of congestion, this is reported from the bus 28 to the protocol processor 21 and terminal line storage device 17 of route fault, and the packet is transferred from a protocol processor 19 to a bypass route.
