Abstract: PURPOSE:To achieve high density and improved orientation properties by adding metal fine grain powder to a pin rearray type ferromagnetic substance with a low transition temperature band. CONSTITUTION:A mixed particle between a fine grain powder consisting of a spin rearray type ferromagnetic substance 10 whose transition temperature band is lower than room temperature (approximately 25 deg.C) and a metal fine grain powder expressed by R', M', and z. (R': a rare-earth element, M': Al, Si, V, Fe, Co, and Mo, 4.4<=Z'<=5.5) is formed at room temperature within magnetic field. After that, the transition temperature band is shifted to a higher temperature side by sintering to form a temperature-sensitive magnetic body 14 where the direction of the axis of easy magnetization becomes parallel to the direction of C axis of crystal exceeding room temperature. The mixture ratio of the metal fine grain powder 12 is 0.01-0.60mol in reference to a spin rearray type ferromagnetic substance 101mol. It achieves high-concentration and improved-orientation properties.

IPC: H01L29/10
Filed: 1985-12-17
Abstract: PURPOSE:To implement high withstanding voltage in a semiconductor integrated thyristor, by providing a reverse-conductivity type high resistance semiconductor layer having a thick step part, providing the gate region of the thyristor, whose conductivity is the same as that of a substrate at the thick part of said layer, and providing the anode region of said thyristor at the thin part of the layer. CONSTITUTION:A voltage is applied between an anode region 4 and a substrate 1 and a gate region 3. Then, depletion layers 6 and 7 are formed at the junction region between the substrate 1 and an epitaxial layer 2. The depletion layer 7 on the side of the epitaxial layer 2 is expanded upward, i.e., toward the side of the surface, at a step part, where the epitaxial layer 2 changes from the thick part to the thin part. At the same time, a depletion layer 8 is formed at the junction between the gate region 3 and the epitaxial layer 2 in the vicinity of the surface by the potential of the gate region 3. The depletions layer 7 merges with the depletion layer 8. Thus the depletion layers 7 and 8 on the side of the epitaxial layer 2 form the surface with a small curvature. Therefore, the concentration of an electric field in the epitaxial layer 2 is alleviated, and high withstanding voltage is further increased.

Title: Lithium secondary battery
Inventor: NAGAI TATSU
IPC: H01M10/05
Filed: 1987-11-10
Abstract: PURPOSE:To increase energy density per volume and weight of a battery by adding a lithium salt to an organic solvent serving as electrolyte solvent in the concentration more than saturation. CONSTITUTION:A lithium salt is added to an organic solvent serving as electrolyte solvent in the concentration more than saturation. In a battery in which lithium salt-saturated electrolyte and the lithium salt coexist, if, for example, LiBF4 is used as the lithium salt, a Li<+> ion in the electrolyte is deposited as Li on a negative electrode and BF4<-> is doped in a positive electrode, then LiBF4 existing in a solid form is dissolved in the electrolyte in a charge process. In a discharge process, BF4<-> undoped from the positive electrode is combined with Li<+> dissolved from the negative electrode to deposite LiBF4, and the electrolyte always retains saturated concentration. The amount of organic solvent serving as electrolyte solvent which has no direct relation to reaction is minimized. Energy density per volume and weight of a battery is increased.

Title: Mounting equipment of semiconductor components
Inventor: OSHIMA YASUTOKU
IPC: H01L21/52
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To save manhour of maintenance and obtain accurate pressing force, by measuring reactive force from a pressing part, operating the spring constant of a compressed spring from resistance of a movable part which is shown by an output before abutting against semiconductor components and an output value of initial pressure, calculating moving amount, and moving the pressing part on the basis of the result. SOLUTION: A spring constant operating means 6 operates the spring constant of an used compression spring 4 from the resistance of a movable part obtained by driving of a pressing part 3 before abutting against semiconductor components 1, the output from a measuring means 30 and the deflection amount of the compression spring 4, and outputs an operated result to a moving amount operating means 7. Since the pressing force to the semiconductor components 1 is uniquely given by the product of the spring constant and the deflection amount of the compression spring 4, the descending amount of a pressing head 2 can be calculated by dividing the set pressing force by the output (spring constant) of the spring constant operating means 6 with the moving amount operating means 7.  The semiconductor components 1 can be always pressed by a set value, by moving the pressing part 3 until the output value is matched with the decending amount of the head 2.
