Abstract: 1,044,332. Magnetically-variable resistors. AGENCY OF INDUSTRIAL SCIENCE AND TECHNOLOGY, MINISTRY OF INTERNATIONAL TRADE AND INDUSTRY. A pril 1, 1963 [June 30, 1962], No. 23261/66. Divided out of 1,044,331 Heading H1K. [Also in Divisions G1 and G4] An electric analogue computing device comprises a thin semi-conductor wafer rotatable with respect to a magnetic field and exhibiting a magneto-resistance effect to give an output proportional to sin 2 # or cos 2 #, where # represents the angle of rotation relative to a datum axis. The wafer should have a thickness less than 1/ 100 of its width and may be an intermetallic compound formed by vacuum deposition. With weak magnetic fields the change in resistance is proportional to the square of the normal component of the field, which may be either unidirectional or alternating.
