摘要:
A magnetic bubble memory device for implementing its high storage density for practical use is generally composed of ion-implanted elements occupying the most part of a minor loop, and other elements made of soft magnetic materials. The ion-implanted minor loop with a higher density is folded several times, and includes straight propagation tracks adjacent to each other and connected by an inside turn, with another straight propagation track having an outside turn facing the inside turn being placed between the adjacent straight tracks.

摘要:
Hydrogen ion is implanted twice or more at different acceleration voltages into desired portions of a magnetic film holding magnetic bubbles to form a magnetic bubble propagation path. This ensures production of an ion-implanted device having a sufficiently large anisotropic magnetic field parallel to the magnetic film and a high Curie temperature.
摘要:
A method of implanting a magnetic garnet film with ions is disclosed in which a covering film is provided on a monocrystalline magnetic garnet film for magnetic bubbles, and hydrogen ions are implanted in a desired portion of a surface region in the magnetic garnet film through the covering film. According to this method, it is possible to form an ion-implanted layer in which the ion concentration distribution in the direction of depth is uniform, and moreover the inplane anisotropy field in the ion-implanted layer decreases only a little with time in an annealing process.
摘要:
Method for immunological analysis of a trace component(s) by labelling an antigen or antibody with a marker comprising causing an immune reaction using an antigen or antibody labelled with a spectral sensitizer as a marker, separating the labelled antigen or antibody from the resulting antigen-antibody reaction product, then bringing either the labelled antigen or antibody and the labelled antigen-antibody reaction product into contact with a silver halide, exposing the resulting system to light having a wavelength which the spectral sensitizer absorbs, developing the thus exposed silver halide and then measuring the resulting density.Trace components can thus be photochemically detected and the amount present quantitatively determined. The method provides high reproducibility and high sensitivity comparable to radioimmunoassay but without any risk of radiation exposure.

A silver halide emulsion comprising silver halide grains covered with two dye layers in combination. The two dye layers comprises an inner dye layer adjoining to the silver halide grain, and containing at least one sensitizing dye capable of spectrally sensitizing silver halide, and an outer dye layer adjoining to the inner dye layer, and containing at least two dyes. The light absorption energy of the outer dye layer is equal to or higher than that of the inner dye layer, an energy-releasing wavelength of the outer dye layer overlaps with an energy-absorbing wavelength of the inner dye layer, the sensitizing dyes constituting the inner dye layer include an anion and/or betaine dyes, the dyes constituting the outer dye layer include an anion and cation dyes, and the anion dye is more than the cation dye in terms of an addition amount and/or an adsorption amount.
