    摘要： A current stretch detection method for a bubble device in which bubbles are written at least one bit apart. A stretch pulse is applied to a stretch conductor so that when a bubble is detected, it is maintained stretched, even though the bubble following it has moved one bit. Preferably the stretch pulse is of a convex-shape. A bubble device has a hairpin stretch conductor and a detecting element disposed centrally in the conductor. The terminal of the detecting element on the higher potential side is arranged so that it does not cross the stretch conductor. The contiguous propagation pattern is provided with a notch at a position in which the stretch conductor is located.

    摘要： A magnetic bubble memory device includes: a magnetic layer with a first region having an easy axis of magnetization extending in a certain direction and a second region surrounding the first region and having an easy axis of magnetization substantially perpendicular to that of the first region, said first region defining a plurality of bubble propagation patterns; and a replicate gate with a stretch conductor pattern, to which an electric current is applied so as to stretch a bubble between said propagation patterns, and a cutting pattern formed in the second region between the propagation patterns and adapted to lower the bubble collapse field so as to cut the stretched domain. The replicate gate is operated by applying an operating current pulse to the stretch conductor pattern, said operating pulse including a stretch pulse for stretching the bubble and a cut pulse, following the stretch pulse, for cutting the stretched domain.

    摘要： A magnetic bubble memory device comprises: a magnetic layer which has a first region having the easy axis of magnetization extending in a certain direction and a second region surrounding said first region and having the easy axis of magnetization substantially perpendicular to that of the first region, said first region defining at least one major loop pattern for propagation of information bubbles and a plurality of minor loop patterns for storage of information bubbles; and an electrical conductor pattern deposited on said magnetic layer in a region in which the major loop pattern and the minor loop patterns are opposed to each other, thereby constructing a transfer gate. The major loop pattern is provided, at the portions thereof substantially opposed to the ends of the minor loop patterns in the transfer gate, with gaps through which the bubbles are transferred between the major loop pattern and the minor loop patterns. The transfer gate is driven by means of a convex-shaped pulse of transfer current.

    摘要： A module for a fiber optic link has a case housing a circuit module plate. An optoelectric element mounted at a predetermined position of lead frames is molded from a transparent transfer molding material. The case has a socket for mounting a fiber cable connector which is molded from a nontransparent injection molding material. A hole in which is inserted a plug of the connector is formed in the socket and the case. The optoelectric element is arranged to oppose the hole of the case through a convex lens segment of the case.
