Title: Improved magnetoresistance transducer
Inventor: JIEIMUZU EI BURUTSUGU
IPC: G01R33/09
Filed: 1993-06-07
Abstract: PURPOSE: To prevent a domain from being formed in a magnetoresistive(MR) element to enable a noiseless operation by forming at least an MR element having an easily magnetizable axis in the lateral direction. CONSTITUTION: In a double-stripe transducer structure the magnetic fields of MR elements 35, 36 are oriented in mutually opposite directions. In a solft- magnetic adjacent layer(SAL) structure the current flows only in one element, but owing to a strong coupling between films, the magnetizations in the elements 35, 36 rotate in the opposite direction. This current is usable for initializing a device into a magnetic state because the magnetic field 39, 40 due to this current and easily magnetizable axes 37, 38 are oriented in the same directions. One of important aspects is to prevent the domain from being formed in the MR element to thereby realize the noiseless operation.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To obtain the automatic wiring system which reduces an error of an area, wherein a bypass pattern of a net having line length specified can be generated, based upon the specified line length by using the area outside a component pin of this net. SOLUTION: The distance from a from pin 11 to a to pin 12 is found from XL+YL. Here, XL is found from the absolute value of the difference in X coordinate between the from pin 11 and to pin 12 and YL is found from the absolute value of the difference in Y coordinate between the pins 11 and 12. Here, when line length which is three times as long as the line length indicated by XL+YL is specified for this net, a bypass 14 is calculated. To derive the path, a pattern is extended upward from the from pin 11 and put in the to pin 12 from the right by generating a box 15 previously according to parameters. Further, the coordinates of a wiring inhibited area 13 are so calculated that the area is generated inside the bypass 14 by the value of a minimum wiring gap W.
