Abstract: PURPOSE: To improve the efficiency of a communication line by catching a multi-person connection trunk at any suitable exchange station by identifying that trunk corresponding to a call setting message composed of a used channel number and a call number different from a spoken call. CONSTITUTION: During speaking with the spoken terminal of another station, a terminal 15 housed in an exchange 1 generates a multiperson connecting request designating the terminal of the third person housed in the other station while using hooking or any specified number. A multi-person connecting request analytic part 120 prepares the call setting message, for which the other call number is set in an information factor while using the same channel number as one used for the spoken call, and sends that message through a communication control part 13 to the following station. At the exchange where the call setting message is received, a message analytic part 121 identifies the call of the multi-person connecting request when the channel number is just under using and the call number is different.  The multi-person connecting request analytic part 120 discriminates the housing destinations of the spoken terminal and the terminal of the third person and a multi-person connecting part 122 catches a multi-person connecting trunk 17.

IPC: H01L21/225
Filed: 1987-05-29
Abstract: PURPOSE:To minimize the rear impurity creeping in case of coating as well as the creeping phenomenon in case of diffusion in order to cut down the time of P-and N-type layer formation to a great extent by a method wherein a semiconductor substrate with a groove cut in the overall peripheral side to extend the creeping distance between the two surfaces. CONSTITUTION:A groove 2 of 50mum in width and of 100mum in depth is formed on the side of a silicon substrate 1 of 250-300mum in thickness. When one side of the silicon substrate 1 with the groove 2 and of a silicon substrate without the groove 2 are spin-coated with a water solution of donor impurity, the substrate 1 with the groove 2 is subjected to the rear source creeping of around 0.2 mm from the periphery of substrate while the substrate without the groove 2 is subjected to the rear source creeping of around 1-2 mm in width. Next, during the diffusion process, the substrate with the side groove 2 is subjected to the diffusion creeping of around 0.3 mm while the substrate without the groove 2 is subjected to the diffusion creeping of 5-10 mm in width. Through these procedures, the surface distance between a surface coated with the N-type source and another surface coated with the P-type source is extended by using the semiconductor substrate with a side groove 2 to restrain the mutual surface diffusion from occurring.
