    Abstract: A pre-amp. (11) is inserted into inside of a head (3) and the line length between a head (3) and a pre-amp. (11) is minimized so that the line noise in the signal is reduced and the shield from the head drum is obtained. And it is able to remove a shielding can, then a product cost could save.

    Abstract: The group secession from an exchange is made by a specific subscriber within the group so that the conventional group secession of individual secessions is prevented. The method comprises the steps: (A) transfering to individual code receiving mode when group secession key is input; (B) transfering secession mode when input individual code agrees with recorded code; (C) storing group secession mode on a memory and standing-by to receive group number when secession type is group secession; and (D) copying data base of sucession group to another memory region and clearing the data base of the secession group.

    Abstract translation: 集团从集团中脱离的行为是由集团内的特定用户进行的，以防止传统的团体脱离个人行为。 该方法包括以下步骤：（A）当输入组脱离密钥时转移到单独代码接收模式; （B）输入个人代码与记录代码一致时转移分离模式; （C）将分组分离模式存储在存储器上并等待，以在分离类型为组脱离时接收组号; 和（D）将成功组的数据库复制到另一个存储区域并清除分离组的数据库。
