Patent JP-H03142824-A (JP)
Title: Planar-type semiconductor device
Inventor: TAKAHASHI HIDEKI
IPC: H01L21/22
Filed: 1989-10-27
Abstract: PURPOSE:To obtain a larger curvature by the same diffusion depth and to enhance a breakdown strength of a p-n junction by a method wherein a semiconductor layer, of a second conductivity type, which has been formed by selectively diffusing impurities at a boundary of a first semiconductor layer of a first conductivity type by using one mask is formed on the surface of the first semiconductor layer. CONSTITUTION:A p-type diffusion layer 2 is formed on the surface of an n-type silicon substrate 1 by selectively diffusing impurities in an end region, i.e., at a boundary, on the silicon substrate 1 by using one mask 3. Thereby, a p-n junction having a curvature r0 which is larger than that in conventional cases (r0>r) is formed. At this time, the mask 3 selectively diffuses the impurities at boundaries of an opening part 3a in the central region and of a plurality of frame-shaped opening parts 3a1 to 3a3 of different widths at its peripheral region and of individual shielding parts 3b in other regions. Its manufacturing method is the same as that in conventional cases except that the mask 3 is used. Since the impurities are diffused gradually at the boundaries of the individual frame-shaped opening parts 3a1 to 3a3, the curvature r0 of the p-n junction becomes large, and a breakdown strength is enhanced even when the silicon concentration of the substrate is the same as that in conventional cases.

Inventor: KOSHINA HIDE
IPC: H01M10/052
Filed: 1985-12-13
Abstract: PURPOSE:To obtain a stable charge and discharge cycle property without the difference of polarization in charging and discharging, by forming a conductive high polymer membrane participating in the charge and discharge reactions at the surface of a fusible alloy negative electrode facing the opposite electrode. CONSTITUTION:Over the surface facing the opposite electrode, of a negative electrode 2 made of a rolled fusible alloy of Pb-Bi-Cd type, a supersonic- deposited polypyrrole membrane 1, which participates in charge and discharge reactions, is pressed on a sealing plate 4 to which a stainless steel negative electrode collector 3 is welded beforehand. Therefore, the membrane 1 itself exercises occlusion and discharge of the negative electrode active substance to eliminate the difference of polarization in charging and discharging, without losing the primary property of the fusible alloy, and restricts the electrolyte resolution over the surface of the alloy 2, so that a stable charge and discharge cycle can be realized.

When the sound pressure level thereof is a predetermined value or more, alarm output 61 is transmitted. Further, the output 61 transmitted from the apparatus 56 is recorded and investigated by a receiving apparatus 62. That is, when it is supposed that an accident point 20 is present between points C, D, a sonic wave 40 propagates left and right, and arrives at the points C, D when the operation time of the apparatus 56 is elapsed and only the apparatuses 50 at the points C, D emit alarm output signals.
