Abstract: PURPOSE:To enhance a current amplification factor and to prevent a breakdown strength between a base and an emitter from decreasing by specifying an impurity concentration near a junction face between an emitter region and a base region and the concentrations of B and Ge in a base region. CONSTITUTION:At least B and Ge are added to a base region 4. When an impurity concentration near the junction face between an emitter region 5 and a base region 1 is ND, the concentration of B in a base region is NB and the concentration of Ge is NGe, ND<=10<19>cm<-3>, and NGe>NB are satisfied. The B and Ge are added to the base region by ion implanting. Further, the ND is set to 10<17>-10<19>cm<-3>. The impurity concentration near the junction face between the emitter region and the base region is suppressed to 10<19>cm<-3> or less to eliminate a band gap narrowing and to prevent a current amplification factor from decreasing.

Title: Superconductive magnet device
Inventor: YAMAMOTO AKIRA
IPC: H01F6/06
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To enable the occurrence of quenching phenomenon in a coil end to be avoided without fail by a method wherein the axial directional electromagnetic force of an arbitrary conductor block is distributed not to exceed the integral value of axial directional electromagnetic force of the conductor blocks inside the former conductor block. SOLUTION: For example, an inner coil 1 is divided into three conductor blocks of 1a, 1b, 1c at the coil end, so as to arrange a center pole 9a in the same size as that of a core tube for arranging end spacers 8a, 8b, 8c between the three conductor blocks 1a, 1b, 1c. In such an arrangement, the sun of the electromagnetic force of the conductor blocks 1a and 1b exceeds the axial directional electromagnetic force 4 of the conductor block on the coil end, so that the compression force may be constantly imposed on the end spacer 8b. Accordingly, the quenching phenomenon on the coil end can be avoided by the friction between the end spacer 8 and the conductor or the cracking of an adhesive.
