摘要： PROBLEM TO BE SOLVED: To provide a spacer material for a flat panel display for reducing distortion and blur of an image, its manufacturing method, a flat panel display spacer and a flat panel display.
SOLUTION: A sintered compact containing Al
2 O
3 , TiC and TiO
2 , containing the TiC of 6.5-10 wt% to the whole weight of the Al
2 O
3 , TiC and TiO
2 , and containing the TiO
2 of 1.0-2.5 wt% is made as the spacer material. Since this material is a composite ceramics containing TiC and Al
2 O
3 , this spacer material exhibits a property of AlTiC to be a conductive ceramics with a high hardness, endures deformation by compression force. Furthermore, since this spacer material has a described composition, it exhibits a desired conductivity even if an electric field is applied, thereby the electrostatic charge is hardly accumulated.

摘要： PROBLEM TO BE SOLVED: To stabilize a detection output, and to prevent breakages in lead conductors for a magnetic sensor of an encoder, such as a GMR sensor, a TMR sensor, etc.
SOLUTION: The sensor pattern surface 21a of a substrate 21 is inclined by a prescribed pitch angle α (desirably, α=0.1 to 5°), with respect to a magnetic medium 15. Dummy chips 23 are attached to the substrate 21 on both the sides thereof in form severally projecting from the pattern surface 21a of the substrate 21 so as to sandwich each other with the substrate 21 in between. A medium slide surface 23a of each dummy chip 23 is chamfered at its corner angle part on a side opposite to the substrate 21. This keeps the detection distance D1 constant at all times, stabilizing the detection output. Since edge portions of the magnetic medium 15 make no contact with the pattern surface 21a of the substrate 21, the lead conductor disposed on the pattern surface 21a will not break. Even if the magnetic medium 15 is rotated, it will not be damaged by the dummy chip 23.

摘要翻译：要解决的问题：为了稳定检测输出，并防止编码器的磁传感器（例如GMR传感器，TMR传感器等）的引线导体的破损。解决方案：传感器图案表面基板21的21a相对于磁性介质15倾斜规定的间距角α（优选为α= 0.1〜5°）。裸片23在其两侧分别安装在基板21上，形状各自突出从基板21的图案表面21a将基板21夹在中间。每个虚拟芯片23的介质滑动表面23a在与基板21相对的一侧的角角部分处被倒角。这始终保持检测距离D1恒定，从而稳定检测输出。由于磁介质15的边缘部分不与基板21的图案表面21a接触，所以布置在图案表面21a上的引线导体不会断裂。即使磁介质15旋转，也不会被虚设芯片23损坏。（C）版权所有（C）2006，JPO＆NCIPI

摘要： PURPOSE:To improve a magnetic characteristic and to reduce manufacturing cost by forming the laminate surface of a magnetic head, for which plural ferrite core pieces are laminated, to be a cut surface, of which surface roughness is rougher than that of a mirror surface, and mutually adhering the cut surfaces. CONSTITUTION:Ferrite core materials 1 and 2 of an L-shaped cross section and an I-shaped cross section are adhered through a non-magnetic material such as glass and further, a non-magnetic panel 3 for reinforce such as ceramic, etc., is adhered. Then, an welding bar 10 is constituted. This bar 10 is cut with prescribed width T in a lengthwise direction and a head piece 6 is obtained. At such a time, the surfaces of cut surfaces 1a and 2a are set so as to obtain the roughness, thickness accuracy and flatness suitable for various conditions required as the magnetic head. For the piece 6, the several cut surfaces are mutually attached to one floppy and head and a back core is fixed. Then, a core assembly body is manufactured. Thus, the dispersion of adhesive intensity is eliminated and the thickness dimension accuracy is made uniform.
