Patent JP-H03155102-A (JP)
Title: Highly conductive magnetic material
Inventor: MORI TOSHIHIKO
IPC: H01B1/02
Filed: 1989-11-13
Abstract: PURPOSE:To acquire high electrical conductivity and good magnetic properties by dispersing and forming ferrite in copper or copper group alloy. CONSTITUTION:For example, a ferrite powder of average diameter of 200mum is added by 2 weight ratio to 1 weight ratio of pure copper powder of average grain diameter of 150mum manufactured by water atomizing method, fully mixed to be pressed-formed to a rod-shape, and sintered in a nitrogen atmosphere. The formed rod has good magnetic properties and high electrical conductivity; the reason is that conductivity lowers only by a volume occupied by ferrite in conductive metal since crystalline lattice of copper is continuous with ferrite and therefore has extremely little distortion. As the magnetic material is provided with magnetic properties and electrical conductivity, it can be used for a relay part wherein a magnetic part and a conductive part are formed integrally.

IPC: H01L21/822
Filed: 1992-11-05
Abstract: PURPOSE:To provide a semiconductor device manufacturing method with which a semiconductor device can be microscopically formed in a highly integrated manner by reducing the dimensional error and also by reducing the dimensional margin between each element. CONSTITUTION:The second polycrystalline silicon 32, which constitutes a capacity storage part, is anisotropically etched by RIE using the first insulating film 27 as an etching stopper.

Also, as the first, the second and the third insulating films 27, 31 and 33 are anisotropically etched by an RIE, the mask 34 to be used when an etching treatment is conducted thereon, may be smaller than that used in the past. Accordingly, each element can be made small in size, the semiconductor device can be brought into a microscopic and highly integrated state.

Title: Resin sealing and filling technique for relay
Inventor: INASAWA YASUYUKI
IPC: H01H49/00
Filed: 1990-10-31
Abstract: PURPOSE:To prevent poor appearance of sealed and filled areas due to resin deposition on unnecessary areas and enable filling in narrow places by using air spraying nozzles to control air pressure for resin filling control. CONSTITUTION:Several air spraying nozzles 2 are arranged in an air pressure controller 1 to fill resin into sealed and filled areas 5 where terminals 4 are protruded on a relay 3 in a thin and uniform fashion while pressure-controlling air sprayed from each of the nozzles 2. Air pressure control is considered to completely seal the sealed and filled areas 5 and still not to deposit resin on the terminal 4 and unnecessary-to-fill areas 6. That is, air pressure control is considered not to deposit resin, in which case adverse effect of flotation occurs in brazing connection between a board and the terminal 4 on the relay 3. It is thus possible to prevent poor appearance of the sealed and filled areas due to resin deposition on the unnecessary areas and simplify filling into narrow places.
