Title: Bypass system at fault
Inventor: SHIMIZU KEIICHI
IPC: H04M3/00
Filed: 1989-12-25
Abstract: PURPOSE:To always ensure a specific route with high priority by informing a fault to an exchange being a caller node in a specific route when the fault of a channel is detected and giving virtual private line information onto a call setting signal of a call using the specific route succeedingly. CONSTITUTION:When a fault takes place in a channel 10, a management equipment 22 analyzes it that the channel 10 is part of the most important route 14 of a relevant private network and informs 'virtual private line station A' and 'opposite station code' to PBXes 1, 4 able to be outgoing nodes of a virtual private line A. When a terminal equipment 5 makes a call to a terminal equipment 6, the PBX 1 gives information of the 'virtual private line station A' to the call setting signal. When the virtual private line A is established and communication is implemented between the terminal equipments 5, 6 and the call is released later, the PBXes 2, 3 being relay stations do not release the channel even when a reply signal to interrupt is received and ensures its resource for the said virtual private line A.

Filed: 1990-11-30
Abstract: PURPOSE:To make it possible to obtain a magnetic recording medium being excellent in an electromagnetic conversion characteristic and durability by a method wherein a specified quantity of iron carbide having spontaneous magnetization is made to be contained in a magnetic layer. CONSTITUTION:Iron carbide from 5 to 10 pts.wt. for 100 pts.wt. of magnetic powder is made to be contained in a magnetic layer. The magnetic powder to be used may be any of metal powder of a magnetic iron oxide, a cobalt- containing magnetic iron oxide, a cobalt-coated magnetic iron oxide, a chromium oxide and a magnetic metal. When BET of the iron carbide to be used is less than 5m<2>/g, besides, the size of a particle of the iron carbide is large, surface properties lower and the lowering of an output and an increase of noise are brought about. When the BET exceeds 20m<2>/g, the size of the particle is small and grindability is not improved. By this method, the grindability and durability of a magnetic recording medium can be improved without lowering a magnetic characteristic.
