    Abstract: PURPOSE:To obtain a magnetic bubble detector in which a power and a dummy are not necessary and an output impedance and a noise are small by combining a soft magnetic thin film pattern and a loop-shaped conductor pattern arranged so as to cross to this and constituting the device so that the magnetic field of the bubble to pass through the soft magnetic thin film pattern can cross the conductor pattern. CONSTITUTION:On a crystal 10 for a magnetic bubble, a loop-shaped conductor pattern 12 is formed through a spacer 11, and on it, a stretcher 15 to line up plural soft magnetic thin film patterns 14 through an insulating layer 13 so as to cross to a conductor pattern 12 is formed. By the magnetic field change when a bubble, in which the loop-shaped conductor pattern 12 is stretched by the stretcher 15, passes, the voltage output occurs at the conductor pattern 12 and the bubble can be detected. The conductor pattern 12 is close to the surface of the bubble crystal 10, can efficiently pick up the magnetic field to come out from the bubble and the output impedance of the detector is also reduced.

    Abstract: PURPOSE:To cause a driving force to be powerful and to prevent erroneous action by linking the outlet side piece of two unit elements in which a bubble magnetic domain transfer stage is arranged to at least one side edge part. CONSTITUTION:Bubble magnetic domain transfer stages 11, in which plural chevron-shaped unit elements 10 of the non-symmetrical structure to make the length of an input side piece 10a shorter than the length of an outlet side piece 10b are arranged at a constant period in the direction perpendicular to the progressive direction of a bubble, are provided in the progressive direction of the bubble. At this time, the outlet side piece 10b of two unit elements 10 of at least one side edge part of the bubble magnetic domain transfer steps 11 is linked with a linking piece 12. In such a way, the moving of the bubble comes to be smooth, the snaking of the stripe magnetic domain comes to be small, further, and since a stable point is changed closer to the outlet, a stripe head part is also smoothly transferred toward the next step. Thus, the deterioration of a high driving low bias side can be relaxed.

    Abstract: PURPOSE: To obtain a magnetic bubble transfer path having small variance of transfer margin to the process fluctuation, by using Two patterns containing a bar pattern piece and a pattern piece having larger width than said bar pattern piece respectively and connecting both patterns to each other in the same way as a linear part.
    CONSTITUTION: Corner patterns 12 and 13 contain bar pattern pieces A and B and pattern pieces E and F having larger width than the pieces A and B and connect the 1st and 2nd transfer paths 10 and 11 together to change the bubble transfer direction counterclockwise by 180°. The edge parts of pieces A and B approximate to each other at an angle θ of about 90°. While the edge part of a piece C of the last pattern 14 of the path 10 approximates to the edge part of the piece A of the pattern 12 at an angle θ' of about 90°. The piece B of the pattern 13 gets close (angle β') to a piece D of the first pattern 15 on the path 11 in the same way of connection (angle β) as that applied to the connection between patterns forming the path 11.

    Abstract: PURPOSE: To obtain the same resistance value among gate conductors of each of both minor loop groups by dividing the minor loops into two groups with different numbers of loops.
    CONSTITUTION: Two divided groups of minor loop blocks C
    1 and C
    2 have different numbers of loops, and the increase of the resistance owing to a conductor winding part 1a is absorbed by the number of loops. Thus the accurate coincidence is secured for the resistance value between gate conductor patterns of both groups without increasing the resistance value. This reduces useless chip space and improves the reliability of conductors.

    Abstract: PURPOSE:To improve transfer characteristics of a corner pattern by specifying the area of the ''Permalloy(R)'' pattern of a return track adjacent to the corner pattern. CONSTITUTION:The ''Permalloy(R)'' pattern 8 of the return track 3 adjacent to the corner pattern 4 is large in thickness and larger in area than any other ''Permalloy(R)'' pattern 1, and a large magnetic pole is induced at the pattern 8 to increase the magnetic gradient between the pattern 8 and a pattern which connects the track 3 and an onward track 2. Consequently, the magnetic bubble transfer characteristics of the corner pattern are improved.

    Abstract: PURPOSE:To supply a rotating magnetic field uniformly in an X and a Y direction by winding to weave an X coil so that the 1st and the 2nd gaps alternate with each other at every turn, and then winding an X coil through the 1st and the 2nd gaps after a chip is inserted into the X coil. CONSTITUTION:The X coil 10 is formed by winding the gap h in order (a-e) so that the gaps alternate with each other at every turn. The X coil 10 is inserted into a ceramic substrate 12 mounted the chip 13 and connected with external terminals through Al wire and a wire material 15 having the same wire diameter with the X coil 10 is wound to weave through the gaps g-1 and g-2 of the X coil 10 to form the Y coil 11. Both X and Y coils have almost the same characteristics, so the chip is supplied with an uniform magnetic field easily.
