A method of manufacturing a magnetic sheet includes a slurry sheet forming step, a local magnetic field applying step, and a slurry curing step. In the slurry sheet forming step, slurry is formed by mixing flat soft magnetic metal powder in a binding material, and a slurry sheet is formed by shaping the slurry into a sheet. In the local magnetic field applying step, only the orientation of the flat soft magnetic metal powder, which exists in the partial area, of the entire flat soft magnetic metal powder mixed in the slurry sheet is unified in a predetermined direction by locally applying a magnetic field to a partial area of the expanded slurry sheet in a predetermined direction. In the slurry curing step, a magnetic sheet is formed by curing the slurry sheet after the local magnetic field applying step.

An antenna coil formed on a substrate surface of an insulating substrate has conductor lines forming four sides of a basic loop shape. Furthermore, the antenna coil has corner lines at a corner portion of the loop. For example, by forming trimming lines on the inner side of one of the corner lines, it becomes possible to adjust the resonant frequency in various ways without considerably disturbing the shape of distribution of magnetic flux density generated by the antenna coil as a whole.

The invention provides a cutting method and a cutting apparatus that cuts without chipping a composite material consisting of laminated layers of crystal material and amorphous material, in which the amorphous material is cut with an ultrasonically vibrated cutting blade and the crystal material is cut with a cutting blade that does not ultrasonically vibrate. With such a method and apparatus, the crystal material portion and the amorphous material portion of the composite material can be cut cleanly without chipping.

An electro-optical device includes, above a substrate: data lines extending in a first direction; scanning lines extending in a second direction and intersecting the data lines; pixel electrodes and thin film transistors disposed so as to correspond to intersection regions of the data lines and the scanning lines; storage capacitors electrically connected to the thin film transistors and the pixel electrodes; and shielding layers disposed between the data lines and the pixel electrodes. Further, nitride films are included in the shielding layers and are formed along the data lines and are wider than the data lines.

A manufacturing apparatus for manufacturing an oriented film of a liquid crystal device holding a liquid crystal between a pair of substrates facing each other, includes: a film formation chamber; an evaporation section evaporating an oriented film material on the substrate by a physical vapor deposition, and forming the oriented film in the film formation chamber; a shielding plate formed between the evaporation section and the substrate, having an elongated opening for selectively evaporating the oriented film material, and covering an area of the substrate on which the oriented film is not formed; and a cleaning section providing a cleaning medium for removing the oriented film material adhered on the shielding plate, toward the opening of the shielding plate, and on the side of the shielding plate that faces the evaporation section.
摘要:
A nonreciprocal circuit element includes a first yoke having an upper plate, a second yoke which has a flat lower plate and forms a magnetic closed circuit together with the first yoke, a flat ferrite member arranged between the upper plate and the lower plate, and first, second and third central conductors arranged to partially cross one another in a vertical direction via a dielectric. The dielectric and the central conductors are arranged on a top surface or a bottom surface of the ferrite member. A coil to which a direct current is applied is arranged at an outer circumference of the ferrite member, such that a direct current magnetic field is generated at the ferrite member by means of the coil. As a result, since a typical magnet is not required, a small nonreciprocal circuit element having the small number of components can be implemented at low cost.
