    Abstract: This invention provides a magnetic bubble memory device comprising a magnetic layer in which magnetic bubbles can be moved and a bubble propagation path defined by a pattern of magnetically soft elements, each of the pattern elements having an asymmetrically crooked or curved shape with an entrance-side segment and an exit-side segment having different lengths. The pattern elements are arranged on the surface of the magnetic layer at a predetermined period in such a manner that the exit-side segment of one of the adjacent pattern elements is opposed to the outer side of the entranceside segment of the other pattern element, with a gap therebetween. The difference in length between the entrance-side segment and the exit-side segment of the pattern element is 10 to 25% of the height of the pattern element. This bubble propagation pattern has a geometry which is favourable for gaining an increase in density and which can provide a high propagation characteristic.

    Abstract: A magnetic-bubble memory device comprises a bubble propagation track defined by patterns of magnetically soft material, along which track magnetic bubbles are propagated in response to an in-plane rotating magnetic drive field. The bubble propagation track has a first track portion (11) and a second track portion (12) and a connection portion (13) for interconnecting the first and second track portions. The first track portion is defined by conventional propagation patterns, and the second track portion is defined by hook-shaped wide-gap patterns. One end part (14a) of the connection pattern is arranged with respect to the end pattern of the first track portion in the same constructional relationship as that between the successive patterns of the first track, and an opposite end part (14b) of the connection portion is arranged with respect to the end pattern of the second track portion in the same constructional relationship as that between the successive patterns of the second track. Such a bubble propagation track makes it possible to realise a 4µm period 4Mb bubble memory.

    Abstract: A magnetic-bubble memory device comprising a bubble propagation path defined by patterns of magnetically soft material, along which magnetic bubbles propagate in response to an in-plane rotating magnetic drive field. The bubble propagation path has a first track and a second track and a connection for interconnecting the first track and the second track. The first track is defined by conventional propagation patterns, and the second track is defined by known hook-shaped wide-gap patterns or modified wide-gap patterns. The connection includes a connection pattern having one end portion arranged with respect to the terminal pattern of the first track in the same constructional relationship as that between the successive patterns of the first track and another end portion arranged with respect to the terminal pattern of the second track in the same constructional relationship as that between the successive patterns of the second track. Such a bubble propagation track makes it possible to realize a 4 .mu.m period 4 Mb bubble memory.

    Abstract: PURPOSE:To provide a plasma display panel in which no side slip takes place between the first base and the second base particularly when they are sealed. CONSTITUTION:Discharged gas is filled in a gas sealing space formed by the first base (10), the second base (20) and a sealing material (13). A pair of structures, namely concave structure (23) and a convex structures (14) for adjusting position of the base are provided on opposed surfaces of the base outside a display area (S) which is to be a discharged area within a gas sealing space, in this plasma display panel.

    Abstract: PURPOSE:To provide manufacturing method of a plasma display panel having a terminal of excellent corrosion-resistance in the case of an AC type plasma display panel formed by an electrode coated with a dielectric layer. CONSTITUTION:After an electrode 12 and its terminal 13 are integrated together on the surface of a substrate 11, the electrode 12 is coated with a dielectric paste 14. A terminal 13 guided to the peripheral region of the substrate 11 is coated with an oxidation proof paste 16, which is primarily composed of very fine powder of zinc oxide but contains no lead oxide. The substrate 11 is heated, to melt the dielectric paste 14 coated on the surface of the substrate 11 and the oxidation proof paste 16, and a dielectric layer 15 and an oxidation proof layer 17 are thus provided.
