The abstract was not in accordance with PCT Rule 8.1(b) because it was more than 150 words in length The abstract has been established by this Authority to read as follows: Composites, designed 'MNPC" materials, are formed by methods of which an exemplary method includes preparing a liquid suspension of magnetic nanoparticles in a carrier liquid in which the nanoparticles are not soluble The carrier liquid can form a rigid polymer matrix for the nanoparticles whenever the earner liquid is exposed to a ngidification condition A first rigidification condition is applied to the suspension to rigidily the earner liquid into the polymer matrix and thus form a rigid MNPC matenal. A fluidizing condition is applied to the rigid MNPC matenal to fluidize the matrix and allow movement of the nanoparticles in the matrix While the matrix is fluid, the MNPC material is magnetically poled by exposure to an external magnetic field
Abstract:
A composition of a crystalline ferromagnetic material based upon nanoscale cobalt carbide particles and to a method of manufacturing the ferromagnetic material of the invention via a polyol reaction are disclosed. The crystalline ferromagnetic cobalt carbide nanoparticles of the invention are useful for high performance permanent magnet applications. The processes according to the invention are extendable to other carbide phases, for example to Fe-, FeCo-carbides. Fe- and FeCo-carbides are realizable by using as precursor salts Fe-, Co-, and mixtures of Fe- and Co-salts, such as acetates, nitrates, chlorides, bromides, citrates, and sulfates, among others. The materials according to the invention include mixtures and/or admixtures of cobalt carbides, as both Co 2 C and Co 3 C phases. Mixtures may take the form of a collection of independent particles of Co 2 C and Co 3 C or as a collection of particles which consist of an intimate combination of Co 2 C and Co 3 C phases within individual particles. The relative proportions of these two phases as well as the morphology of each phase contribute to their attractive permanent magnet properties, particularly at low temperatures through room temperature and up to over 400 K.
Abstract:
In the present invention, a program stored in a portable memory device is executed in a terminal in such a way that a user can use a service more conveniently, and device-identification data relating to the portable memory device and user-identification data relating to the user are utilized in such a way as to ensure security and at the same time increase convenience when using the service, with the aim of increasing usefulness for service users utilizing an approved portable memory device. To this end, the present invention provides a method for providing a service using device-identification data, comprising: a device-authorisation step in which device-identification data stored in a portable memory device is transmitted to an approvals server; a user-authorisation step in which user-identification data requested by the approvals server is input and transmitted if it is found that the device-identification data is registered on the approvals server as a result of the transmission in the device-authorisation step; an issuing step in which an approval code generated by the approvals server is received and stored if the user-identification data is confirmed by the approvals server; and a usage step in which the stored device-identification data and approval code are transmitted to the approvals server and the service is used. The present invention also provides a device for the above method, and also a computer-readable recording medium on which is recorded a program for executing each of the steps by means of a computer.

Die Erfindung betrifft eine einfache Schnelldiagnose für Tuberkulose ohne aufwendige Laborhilfsmittel mit Hilfe neuartiger magnetischer und/oder gefärbter Polymerpartikel, die in der Lage sind, sich über immobilisierte Bakterien-spezifische Liganden, sich an die Bakterien oder infektionsauslösende komplementär anzulagern und dadurch einen visuell detektierbaren magnetischen und/oder gefärbten Cluster zu bilden.
Abstract:
The invention relates to the use of a powder composition comprising at least 95% by weight of magnetite (Fe3O4) particles as a magnetisable component in a medium for magnetically storing information. At least 99,9% by weight of the magnetite particles have a particle size of less than 5 μm, and the magnetite particles have a polyhedral shape and essentially isotropic magnetic properties. The magnetite particles have a saturation magnetisation of 75-95 emu/g at 10 kOe, a remanence of 20-40 emu/g and a coercivity of 250- 500 Oe. The invention also relates to the medium for magnetically storing information comprising magnetite particles.
