摘要： PROBLEM TO BE SOLVED: To provide an opening and closing device for use in various electronic devices, which is manufactured at low cost and ensures its opening and closing operation. SOLUTION: By elastically bringing a movable cam 37 which is projectingly formed on the inner periphery of a substantially ring-like movable body 36 into contact with an inverse cam 44 after the inverse cam 44 has moved in the axial direction, the movable cam 37 is rotated at a predetermined angle while elastically in contact with the inverse cam 44. Accordingly, it is unnecessary to provide a fixed cam 32 on a stator 31 within a region corresponding to the rotation angle of the movable cam 37. Since the fixed cam 32 is formed not wholly but only partly on the outer periphery of the stator 31, the stator 31 is manufactured relatively easily by molding or the like. The opening and closing device is thereby manufactured at low cost, which ensures its opening and closing operation. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：提供一种用于各种电子设备的开闭装置，其以低成本制造并确保其打开和关闭操作。解决方案：在反相凸轮44沿轴向移动之后，通过弹性地使在大致环状可动体36的内周上突出形成的可动凸轮37与反向凸轮44接触，凸轮37以与反转凸轮44弹性接触的方式旋转预定角度。因此，不需要在与可动凸轮37的旋转角度对应的区域内的定子31上设置固定凸轮32.由于固定凸轮32不是完全地但仅部分地形成在定子31的外周上，所以通过模制等相对容易地制造定子31。因此，以低成本制造开闭装置，确保其开闭动作。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To improve the assembling yield of a disk device by limiting the disk surface sticking of foreign objects to a minimum during disk device assembling.
SOLUTION: A first substrate 2 having a spindle motor 1 fixed to a magnetic disk, and a second substrate 6 having a head support arm 9, a head amplifier substrate 7, and a a lamp block 10 are stacked to assemble the device. A load adjusting mechanism is disposed in the head support arm 9 to adjust a load after the head support arm is assembled on the second substrate. Thus, since no component is stacked on the magnetic disk during assembling, foreign objects stuck to the disk are eliminated as much as possible, and a variance in load on the head support arm is eliminated.

摘要： PROBLEM TO BE SOLVED: To provide a spindle motor that suppresses the generation of cogging torque and whose weight is reduced, and provide a disc drive provided with it. SOLUTION: A chassis 10 passes between mounted surface of the disc 6 in a rotary hub 2 and a stator 17, and a plurality of through-hole windows 10a are opened at a portion facing the outside circumferential surface of a rotary magnet 4. Tip ends of a plurality of magnetic pole teeth 12a of the stator 17 enter the through-hole windows 10a, and also face the rotary magnet 4 in such a way that the inside circumferential surface of the tip ends of a plurality of the magnetic pole teeth 12a of the stator 17 and the inside circumferential surface facing the rotary magnet 4, of the chassis 10 which faces the rotary magnet 4 are roughly on the same circumferential surface. This constitution much reduces change in magnetic flux distribution that is caused by positional relation between the openings of the slots of the stator 17 and the rotary magnet 4, which decreases the generation of the cogging torque drastically. As a result, the excellent spindle motor that rotates smoothly can be realized. COPYRIGHT: (C)2005,JPO&NCIPI
