Title: Magnetic bubble transfer line
Inventor: MIZUNO KENJI
IPC: G11C11/14
Filed: 1983-04-14
Abstract: PURPOSE:To retain bubble stably even when a driving magnetic field is not applied by making the radius of curvature of terminal of a contiguous disk bubble transfer line larger than a specified value of nominal diameter of the magnetic bubble. CONSTITUTION:If (d) represents nominal diameter of a bubble, abacus beads like patterns 1 are arranged repeatedly at a period of 4d, and curvature of terminals 2, 3 is made above 2d. In a CD bubble transfer pattern, the relation between a static hold magnetic field required by a bubble that stayed at the corner to stay at the place after the driving magnetic field is cut off and the radius of curvature is; the larger the radius of curvature of the corner, the smaller the magnitude of necessary hold magnetic field, and when the radius of curvature is about 1.9 micron, necessary hold magnetic field becomes 0. As nominal diameter of the bubble to be used is 1 micron, if the radius of curvature of the corner is 2.0 micron, i.e. more than twice nominal diameter of the bubble, applying of a hold magnetic field at the tme of starting/stopping of the bubble becomes unnecessary.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To evade the breakage of a transmission and a differential gear surely even the trouble time of a control system while ensuring a commercialism. SOLUTION: The existence/absence of the trouble in a control system (for example, engine control module) is detected (S1) and at the existence time of the trouble, the maximum opening NTVOmax of a throttle valve opening control is made to a prescribed upper limit value NTVOFAL (S2, S5-S8). Thereby, as the racing state at the N or P range time can be regulated (evaded), even at the trouble time of the control system, the load applied to the transmission and differential gear can be reduced surely and even if the transmission and differential gear are lightened, they can be protected surely. When the control system is normal, as the racing state is allowed at the N or P range time as usual (S3, S5-S8), a commercialism can be maintained highly.
