Title: Voice coil motor
Inventor: KITA YOZO
IPC: H02K33/18
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a voice coil motor which can be positioned at high speed and with accuracy, without radial load working on the bearing for supporting a head carriage rotatably. SOLUTION: Two coils 51, 52 of the voice coil motor are rotatably disposed inside a magnetic gap comprising a permanent magnet 12 and a pair of yokes 11, and have radial extensions 51a, 51b, 52a, 52b contributing to torque generation. Further, the coils are overlapped in the direction along the rotating axis O with respectively different opening angles of the radial extensions 51a to 52b. Therefore, radial load would never act on the coils when the coils are energized and, resultant generated in the coils would structurally turn to a couple vertical to the moving direction of the magnetic head. As a result, it is possible to position the magnetic head at high speed and besides with accuracy, and this voice coil motor can downsize a magnetic disk device.

Title: Magnetic recording medium
Inventor: YASUI MASAAKI
IPC: C09D7/12
Filed: 1990-11-29
Abstract: PURPOSE:To obtain a good anti-mold effect and to prevent head clogging due to plasticization of a magnetic layer by applying an anti-mold agent as top coating by a specified proportion on a magnetic recording layer preliminarily formed. CONSTITUTION:An anti-mold agent is applied as top coating by 1-10mg/m<2> on the magnetic recording layer of the magnetic recording medium having the magnetic layer on one side of a nonmagnetic supporting body. If the proportion of the anti-mold agent is <1mg/m<2>, the anti-mold effect is not enough, while if the proportion exceeds 10mg/m<2>, the anti-mold agent on the surface of the recording layer is transferred to a magnetic head to cause head clogging. The anti-mold agent is bromcinnamaldehyde, 2-(4-thiazolyl)-benzimidazole, etc. The anti-mold agent is dissolved in an org. solvent to prepare a coating liquid, which is then applied on the surface of the magnetic layer. Thereby, the obtd. recording medium is excellent in anti-mold property and hardly causes head clogging due to plasticization of the magnetic layer.

Title: Linear driver
Inventor: SAWAI HIROYUKI
IPC: G03G15/00
Filed: 1988-12-27
Abstract: PURPOSE:To realize cost reduction and fast driving by setting the thrust generated by a linear motor corresponding to a guide member side larger than that generated by another linear motor. CONSTITUTION:The thrust generated by the linear motor 20 corresponding to the guide member side is set larger than that by the linear motor 20 positively. Namely, the thrust generated by the linear motor 20 is made larger than that by the linear motor 10 by the quantity of thrust unbalance (corresponding to the thrust difference between the linear motors 10 and 20 due to some reason) and then a force F0 operates on the part D of a coupling member 30 in a figure to make a driving point O deviates from on the copying member 30, thereby maintaining a state of x>y in the figure. Further, this state is maintained even when the thrusts generated by the linear motors 10 and 20 are set large, so an optical mechanism is driven smoothly at a high speed. Consequently, the cost reduction and speed increase of a copying machine are prompted.
