Title: Voice coil motor
Inventor: MIYAMOTO TADAHIRO
IPC: H02K33/18
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To increase the efficiency and lessen side force by lessening leakage magnetic flux which flows from a main permanent magnet which generates main magnetic flux to a side yoke and an outside yoke. SOLUTION: An outside yoke 1 and a center yoke 2 are placed face to face at a space G and side yokes 3 to connect both ends of the ouside and the center yoke 1, 2 are placed, forming magnetic paths. A main permanent magnet 4 is fastened to at least one facing face of each space and a coil 5 is located in the space G. In the voice coil motor of such a structure, auxiliary permanent magnets 8 are installed by one pole face on the inner faces of the side yokes and the other pole faces are let to face the space G to make the polarity of the pole face facing the space the same as the space-side polarities of the main permanent magnets 4. Due to this structure, magnetic fields at the ends of the main permanent magnets and those of the auxiliary permanent magnets are the same.  As a result, the leakage of main magnetic flux is lessened and a vector component square to the main magnetic flux is lessened to reduce side force.

Title: Apparatus having magnetic recording head and matrix apparatus having magnetic head
Inventor: JIYOSEFU KORINOO
IPC: G11B15/12
Filed: 1989-10-27
Abstract: PURPOSE: To remove the parasitic signals under reading by having two pieces of magnetic poles separated by a gap and forming this gap of a magnetic material having the saturation degree lower than the saturation of a material constituting these magnetic poles. CONSTITUTION: The gap is composed of the magnetic material having the saturation degree lower than the saturation degree of the material constituting the magnetic poles. The gap is so formed that a magnetic field exists in the gap when the material is not satd., by which a supporting body is prevented from being influenced by this magnetic field. Namely, the supporting body is not magnetized when the absolute value of the sum of the currents of conductors 131 and 141 does not exceed 1/3 of the desired value I0 . On the other hand, the magnetization of the supporting body arises immediately when the absolute value of this sum exceeds I0 /3. This I0 /3 is the start value to saturate the magnetic of the gap 20. The magnetic head enables the magnetization of the supporting body only when the magnetic flux exceeds the desired threshold value.  The parasitic signals under reading are thereby removed.
