摘要： PROBLEM TO BE SOLVED: To provide a storage medium achieving various surface roughness on its surface at a low cost, and a method for manufacturing the same.
SOLUTION: In the method for manufacturing the storage medium 14, a first pattern is established in a data region 31 based on the arrangement of a magnetic substance 32 and a nonmagnetic substance. On the other hand, a second pattern different from the first pattern is established in a non-data region 35 based on the arrangement of the magnetic substance and the nonmagnetic substance. As a result, when the data region 31 and the non-data region 35 are flattened under the same condition, the surface of the data region 31 has a first surface roughness, and simultaneously the surface of the non-data region 35 has a second surface roughness larger than the first surface roughness. Various surface roughnesses are established on the surface of the storage medium 14 through one flattening treatment. The manufacturing cost of the storage medium 14 is reduced.

摘要： PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of efficiently absorbing large impact energy at low cost.
SOLUTION: A resilient member 22 is curved and extended between a first contact surface 23 brought into contact with a housing 12 and a second contact surface 24 brought into contact with an accommodation unit 17. As the first contact surface 23 and the second contact surface 24 approach to each other, the curvature of the resilient member 22 increases. When external impact is applied to the housing 12, the resilient member 22 absorbs the impact energy. At the initial stage of absorbing the impact, because the curvature is small, the resilient member 22 is hardly deformed. A large spring constant is secured. Large impact energy is absorbed per unit stroke. Thereafter, the spring constant is gradually reduced with the increase of the curvature. A soft spring is achieved by the resilient member. In contrast to a linear spring and a hard spring, the impact force transferred to the accommodation unit 17 is reduced. Even when a gap between the housing 12 and the accommodation unit 17 is narrow, the impact energy is efficiently absorbed.

摘要翻译：要解决的问题：提供能够以低成本有效地吸收大的冲击能量的电子设备。解决方案：弹性构件22弯曲并在与壳体12接触的第一接触表面23和与接纳单元17接触的第二接触表面24之间延伸。作为第一接触表面23和第二接触表面23 接触表面24彼此靠近，弹性构件22的曲率增加。当对壳体12施加外部冲击时，弹性构件22吸收冲击能量。在吸收冲击的初始阶段，由于曲率小，弹性构件22几乎不变形。一个大的弹簧常数是固定的。每冲程能吸收大的冲击能量。此后，随着曲率的增加，弹簧常数逐渐减小。软弹簧由弹性构件实现。与线性弹簧和硬弹簧相比，转移到调节单元17的冲击力降低。即使当壳体12和调节单元17之间的间隙较窄时，冲击能被有效地吸收。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a magnetic medium that contributes to reduction in cost and shortening of working time. SOLUTION: When a mold 43 is superimposed on the surface of a magnetic layer 41, resist films 42 are pushed into grooves 46. The displaced resist films 42 will solidify, while the contact with the mold 42 is maintained. The mold 43 is exposed to a magnetic field 49. Magnetic flux flows in between the magnetic materials 47. Leakage magnetic fields are formed in the magnetic layer 41. Magnetic information is written to the magnetic layer 41 by the action of such leakage magnetic fields. Magnetic information, such as, servo pattern, is thus established in the magnetic layer 41. At the same time, the positions of, for example, recording tracks and separation tracks, are specified, on the basis of the resist films 42 in the grooves 46. The magnetic information and the recording tracks can be positioned relatively simply with high accuracy. Such manufacturing method contributes to the reduction of the cost and the shortening of the working time. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PURPOSE:To narrow the distance between adjacent positions where a traveling body temporarily stops by forming the electrode pattern of a fixed body with a plurality of electrode pattern parts and laying out each electrode pattern part while shifting the electrodes by a specific pitch. CONSTITUTION:When a switch circuit 120 is switched and connected to a group of terminals 101-1-101-3, electrostatic repulsion force and electrostatic attraction force are applied among electrodes 70-1-70-6 thus enabling a specific point 122 to stop temporarily and rotating by an angle (p) at a time for stepping operation. The electrodes 70-1-70-6 are laid out at an angle pitch of (p) and while being shifted by, for example, p/3 for electrodes 68-1-68-6. Therefore, by properly switching a switch circuit 120, a position where a rotor 53 temporarily stops is determined with a thin resolution of p/3, thus determining the position where the traveling body temporarily stops to be thinner by several times as compared with a conventional method.
