Title: Brushless motor and polygon scanner
Inventor: SUZUKI MITSUO
IPC: G02B26/12
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce the diameter of the magnet of a facing type brushless motor, improve its responsiveness and reduce its power consumption. SOLUTION: An annular recessed trench 35 which is loaded with ballancing weights in order to adjust the balance of a rotor 34 is formed in the inner circumference part of a driving magnet 33. As it is not necessary to extend a yoke 32 and form the recessed trench 35 in the outer circumference part of the driving magnet 33, the diameters of both the driving magnet 33 and the yoke 32 can be reduced. Further, as the recessed trench 35 is provided in the inner circumference part where the torque is not generated by the driving magnet 33, the diameter of the driving magnet 33 can be reduced while sufficient driving torque is maintained.

Title: Magneto-optical material
Inventor: FUKUDA KAZUO
IPC: G11B11/10
Filed: 1985-11-19
Abstract: PURPOSE:To reduce the variance in the inversion magnetic field in spite of the titled magneto-optical material using a polycrystal by using garnet having specified lambda111 and lambda100 as the polycrystal garnet. CONSTITUTION:A polycrystalline Bi-substituted rare earth iron garnet film having a compensation temp. is formed on an amorphous substrate to obtain the magneto-optical material. The garnet crystal wherein the ratio K (lambda111/lambda100) of the magnetostriction constants in the <111> and <100> directions is adjusted to 1/5-5 is used in the Bi-substituted rare earth iron garnet film. When the K value is lower than 1/5 or higher than 5, the magnetic characteristic in the direction vertical to the film face is widely distributed due to the variance in the crystal axis of the crystal grain. When the ratio K of the two magneto- striction constants is controlled to 1/5-5, or preferably to 1/3-3, the magnetic characteristic in the direction vertical to the film face is not fluctuated even when the crystal axis of the crystal grain is varied.
