Patent JP-S63299271-A (JP)
Title: Composite transistor
Inventor: TOMOSHIGE WATARU
IPC: H01L27/08
Filed: 1987-05-29
Abstract: PURPOSE:To realize a high speed by a method wherein, in a Darlington- connected transistor, a depth of an emitter region of a transistor in a posterior stage is formed to be shallower than an emitter region of a transistor in a preceding stage. CONSTITUTION:A junction depth xj' of an emitter in a posterior stage is constituted to be shallower than a junction depth xj of an emitter in a preceding stage. That is to say, because the depth xj' of the emitter region is shallower than a width wb of a base is wide in a transistor in the posterior stage, a peak value of a current-amplification factor (hfe) is small as shown by a curve (b). As a result, a charge stored in the posterior stage in an OFF state is easily sucked out as compared with a conventional structure; when a transistor in the preceding stage is turned off, the charge in the transistor in the posterior stage is hardly left. In addition, as shown by a straight line (i), an off-time value (tf) is small in an overall range of the amplification factor as compared with a straight line (ii) of the conventional structure; this is suitable for a high- speed switching operation.

Abstract: PURPOSE:To obtain an artificial tooth which is small, large in a suction force, and excellent in abrasion and wear resistance by being composed of a magnet body, in which an S pole and an N pole are provided opposite to both yokes, at a spacer composed of an abrasion and non-magnetic alloy and the reverse root surface plate side of the spacer and a case composed of the abrasion non-magnetic alloy crowned by excluding the root surface plate side of a pair of yokes and spacers. CONSTITUTION:A magnet body 12 is arranged while an S pole and an N pole are faced to yokes 11 and 11 at both sides. A root surface plate 93 uses a soft magnetic alloy, the yokes 11 and 11 use a wear resistance soft magnetic alloy, a spacer 13 and a case 14 use the abrasion non-magnetic alloy and the magnet body 12 uses a rare earth alloy. In the lower edge surface, the section among the case 14, the spacer 13 and the yoke 11 is mutually hard-soldered. By changing the saturated magnetic flux density of the soft magnetic alloy of the yoke 11 and the maximum energy density of the magnet body 12, the suction force is changed, and the high suction force can be obtained by selecting both characteristics. Thus, a small sized artificial tooth attachment, in which the suction force at the section of the root surface plate 93 is strong, the abrasion and wear resistance are excellent, can be obtained.

Title: Low resistance current lead material and manufacture thereof
Inventor: HAYASHI SEIJI
IPC: H01F6/00
Filed: 1991-05-11
Abstract: PURPOSE:To enable high current conduction with the conduction effective area as a lead material enlarged markedly by heating Ag or Ag alloy compounded as an oxide superconductor lead connection terminal under an oxygen pressurization to melt only Ag or Ag allay. CONSTITUTION:An oxide superconductor rod of 5mm diameter consisting of Bi2Sr2Cu2Ox is prepared. This rod consists of many single crystal zones: it is polished into pencil points in both ends, wound close with an Ag wire of 50mum diameter around the polished zone, charged into an O2-HIP device, and heated for two hours at an oxygen partial pressure 200atmX750 deg.C. When the rod is taken out after cooling and observed in the Ag wire wound part 2, it is confirmed that this part 2 melts under the above-mentioned heating condition and that the oxide superconductor rod l joins close to the ends. This way of heating in a pressurized oxygen atmosphere enables only Ag to be melted to join close to the oxide superconductor in a molten state, thereby causing high current to flow.
