摘要:
There are provided a magnetic thin film utilizing a granular film and having excellent high frequency characteristics and a method of manufacturing the same, and a multilayered magnetic film and magnetic components and electronic equipment utilizing the same.A nonreactive sputtering is performed so that there is no oxidation of a magnetic metal, and a saturation magnetization is increased to increase a resonant frequency of permeability. Also, a multi-target simultaneous sputtering is combined with the nonreactive sputtering so that in a granular structure including magnetic grains and an insulating layer a size of the magnetic grains and a thickness of the insulating layer are optimized thereby ensuring a proper magnitude for a crystalline magnetic anisotropy within the grains and excellent soft magnetic properties. Further, the optimization of the thickness of the insulating layer has the effect of improving a resistivity, decreasing an eddy current and improving an exchange interaction between the magnetic grains.

A laminated magnetic thin film has a laminated structure in which insulating layers and granular layers are formed alternately on a substrate. The insulating layers are formed of SiO2 films. The granular layers are formed of FeNiSiO films and have a structure in which an insulator is present in grain boundaries so as to wrap magnetic particles. It is possible to improve insulating properties of the insulating layers and the insulators and increase resistivity thereof by heating the substrate at the time of film formation. It is possible to control deterioration of a magnetic characteristic due to an increase in a resistivity and realize both a high magnetic characteristic and a high resistivity by changing thicknesses of the insulating layers and the magnetic layers and a ratio of the magnetic particles to the insulator to optimize a diameter of the magnetic particles having a composition within a predetermined range.

A transmission cable and method for manufacturing same are provided. A plurality of signal lines are formed on one side of an insulating layer and ground lines are formed between the signal lines. The ground lines are electrically connected with a shield layer formed on a back surface of the insulating layer through metal bumps formed and embedded in the insulating layer. Insulating layers and shield layers may be formed on opposite sides sandwiching the signal lines and the ground lines. In this case, the ground lines are electrically connected with the shield layers, respectively, through metal bumps on both sides thereof. Consequently, a highly reliable transmission cable capable of high rate transfer and large capacity transfer can be provided.

There is provided a flexible circuit board 22 that, when deposited on another flexible circuit board 40, causes no gap to occur between wiring films 4a, 4a, of the flexible circuit board 40. Moreover, a plurality of flexible circuit boards are deposited on one another to provide a flexible multi-layer wiring circuit board having no gaps between the flexible circuit boards and having less bowing. In the flexible circuit board 22, the thickness of a bonding layer 16, 16a, on the opposed side of a bowing metallic member 2, of an inter-layer insulating film 10 where which bumps 6 are formed is greater than the thickness of a bonding layer on the side of metallic member 2. When the flexible circuit board 22 is deposited on the other flexible circuit board 40 to form a flexible multi-layer wiring circuit board 50, the bonding layer 16, 16a can be filled between the wiring films 4a, 4a, so that the flexible multi-layer wiring circuit board 50 has no gaps and a less bowing.
摘要:
In a stencil printer, a drum has the outer periphery thereof formed by a porous sheet having passages for ink therein. The passages are each configured such that the ink entered an inlet pore is diverted from a single perpendicular to the drum at least once, and then flows out via at least one of outlet pores. The pores of the sheet are sized smaller than perforations to be formed in a stencil.

Video signals representative of photographic images which are stored in a plurality of substantially equally dimensioned frames in horizontal and vertical positions are produced by picking up the images. A first signal indicative of a horizontal/vertical position and a top-bottom orientation of the photographic image stored in any of the frames is entered. The photographic image is rotated relatively in response to the first signal. For a vertically positioned image, a video signal is produced which is representative of the image with a magnification which is smaller than that of a horizontally positioned image. Such a procedure provides a video signal which represents an image in a non-inverted top-bottom orientation without any essential portions of the image being omitted.

A molding composition is obtained by blending flaky graphite with a resin component comprising a mixture of a thermoplastic resin having a glass transition temperature higher than room temperature and another thermoplastic resin having a glass transition temperature lower than room temperature. The composition is kneaded and rolled into a sheet to orient the graphite flakes parallel to the surface of the sheet. The rolled sheet is then molded into an article, for example, speaker diaphragm, arm pipe and head shell, which may be optionally be carbonized or graphitized. The resulting article exhibits improved physical properties, especially high specific modulus of elasticity comparable to aluminum and beryllium as well as good internal loss comparable to paper.

A stencil printer of the present invention includes a printer body, a print drum rotatably mounted on the printer body, a press roller for pressing a sheet against the circumferential surface of the print drum, and a moving device for selectively moving the press roller into or out of contact with the outer circumference of the print drum. The press roller and moving device are capable of being pulled out from the printer body integrally with each other.
