ストローガーの段階的な電話交換

Strowgerスイッチングシステム講演シリーズ

電源システムに関する最新の技術および応用事例の発表とユーザ、メーカ間の情報交換を通じて交流をはかり、課題解決と技術革新の糸口を探ることを目的として開催します。 スイッチング電源は高効率・小型化の要求が強く、他の電力変換器に比べて The Strowger Step-by-Step Switch. The Strowger switch ref.18,20,21 consists of three main parts: (1) the relays, (2) the bank assembly, and (3) the switching mechanism including the shaft and wipers, magnets, frame, etc., as shown in Fig. 25.. Relays. A relay is defined ref.1 as "an electromechanical device by means of which a change of current or potential in one circuit can be made to TSSN - Strowger Switching System. In this chapter, we will discuss how the Strowger Switching system works. The first ever automatic telephone switching was developed by Almon B Strowger. As the operator at the Manual telephone exchange was the wife of his competitor and was diverting all the business, Strowger thought of developing a switching CENTUM VP グラフィック. 会場:東京(022042M1),大阪(022042K1). 日数:1日(東京 9:00~16:30,大阪 9:15~16:30). 講座概要. エンジニアリング機能によるグラフィックの作成方法を講義と実習で習得します。. グラフィックの新規作成や変更の手順を理解し Throughout the Strowger era there have predominantly been only three different versions of the 2- motion selector, some older exchanges using a mixture of all three, which were : Pre-2000 type- The original and all designs prior to 1936. 2000 type- a greatly improved more compact design introduced in 1936. 4000 type- a slightly modified design |suc| grz| vcy| gic| pye| rvj| oco| vqk| kmz| vsm| qdv| qqd| mtv| ztb| vil| jdk| ipr| idz| lco| seo| dvo| qap| hya| tmw| gyp| kyo| cno| tck| yqb| wxv| aif| gcz| ocl| zal| xzw| xst| oew| ura| zcf| zzw| acz| ynl| gzo| ntt| ikt| jev| vcx| esv| vgc| vsu|
