Polymer coated ferromagnetic particles could be obtained giving a solution to a problem of difficulty in dispersing ferromagnetic fine particles to a level of monodispersion because of their properties apt to form aggregates. Providing hydrophilic character to hydrophobic ferromagnetic particles obtained by adsorbing hydrophobizing agent to hydrophilic ferromagnetic particles, and dispersed using nonionic surface activating agent suppressing ionic strength increase of the particles. Monomer liquid was emulsified using nonionic surface activating agent and ionic surface activating agent. Mixing the dispersion liquid of ferromagnetic particles and the monomer emulsion were mixed and emulsion polymerization was conducted. Then well-dispersed homogeneous and stable polymer coated ferromagnetic particles showing good response to magnetic field were obtained.

A ferrite film is formed by regularly arranging constituents such as magnetized grains or one analogous to that. In the ferrite film, the constituents have at least one of the uniaxial anisotropy and the multiaxial anisotropy. The ferrite film has the magnetic anisotropy or the magnetic isotropy. The ferrite film is formed by the use of the plating method in the presence of a magnetic field. Furthermore, an electromagnetic noise suppressor includes the ferrite film.

In quartz glass parts and ceramic parts that are used in film-deposition devices and pre-cleaning devices in the production of semiconductors, etc., there are problems such as peeling off of the parts themselves during the use, peeling off of film-like substances adhered to the part surfaces, contamination of the products and short life time of the parts caused by corrosion of the part surfaces by plasma, and reduction in the productivity by frequent exchange of the parts. In quartz glass parts and ceramic parts that are used in film-deposition devices and pre-cleaning devices in the production of semiconductors, etc., with respect to parts, the surface of which is constituted of a ceramic thermal sprayed coating, ones having the ceramic thermal sprayed coating having a surface roughness Ra of from 5 to 20 μm are high in adherence of a film-like adherence, ones having the ceramic thermal sprayed coating having a surface roughness Ra of from 1 to 5 μm are high in plasma resistance, and ones in which grooves having a large anchor effect to the thermal sprayed coating is formed on a substrate on which the ceramic thermal sprayed coating is formed are free from peeling off of the ceramic thermal sprayed coating from the substrate and are high in durability.

A ferrite bonded organic substance having that has a strong bond between organic substance and ferrite can be obtained by carrying out formation and bonding of a ferrite to an organic substance having a functional group selected from a carboxyl group, a mercapto group and a mercapto group in oxidized form. In the producing method of manufacturing the ferrite bonded organic substance, ferrite plating can be employed. Wide application in, for example, various drugs, bio-analytical reagents, DNA, various contrast media and MRI sensitizers that permit magnetic manipulation can be realized by bonding ferrite to organic substance retaining a bio-active substance.

A tape cassette housing a cassette main body unit a pair of tape reels. The cassette main body unit is made up of an upper cassette half and a lower cassette half, and a tape-shaped recording medium is placed between the tape reels. One of the cassette halves constituting the cassette main body unit has a reel unlock unit engaged by engagement members of various portions of other mechanical units excluding a tape driving unit on the recording and/or reproducing apparatus and a frame unit of a synthetic resin having an integrally formed design statement detection unit or a loading reference used for loading the tape cassette on a recording and/or reproducing apparatus. The frame unit also has, as an aperture, a portion registering with a tape reel rotation area on its bottom side, and a metallic plate integrated into the aperture for forming a portion of the tape reel rotation area on the bottom of the frame unit. The metallic plate has a pair of reel bearing holes into which is intruded the tape driving unit. The metallic plate is integrated by insertion molding into the aperture of the frame unit. The main body unit of the tape cassette is made up of the frame unit of synthetic resin and the metallic plate for realizing sufficient mechanical strength against warping or distortion and maintaining the overall weight of the tape cassette.
摘要:
In a short-time recording tape cassette having a mouth section for receiving a head drum, a pair of tape reels can be moved to a rear portion in a cassette case of the tape cassette upon loading of the tape cassette into a recording/reproducing device, thereby eliminating a dead space in the cassette case and further expanding the mouth section. Accordingly, a more compact construction of the recording/reproducing device can be realized. Moreover, a spring for biasing the tape reels is configured in a substantially S-shaped cross section, so as to make a biasing force of the spring against the tape reels before the movement of the tape reels substantially equal to that after the movement of the tape reels.
