Title: Magnetic head material
Inventor: SASAKI MASAYOSHI
IPC: G11B5/60
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic head material capable of preventing head creaks or sucking of head by incorporating a specified proportion of magnesium oxide into a ceramic material which forms the contact part (slider) with a magnetic medium. SOLUTION: Silicon oxide (SiO2 ) and magnesium oxide (MgO) are added to a ceramic material, which forms a slider 12 of a magnetic head. Especially, by incorporating MgO to be 3% or higher of the component proportion, the surface 12A after mirror polishing can be controlled to desired average roughness and maximum roughness. The reason is that the added MgO forms recesses 23 of about 10 nm depth on the surface 12A, and the recesses 23 have a larger area compared to shallow flaws 21. The recesses are dispersed with low density compared to deep flaws. Therefore, raggedness with low density is formed on the surface of the slider 12, which prevents scratches on the surface of an FD or decrease in the magnetic efficiency of the magnetic head.

Title: Semiconductor surface protective resin composition
Inventor: SANO YASUSHI
IPC: H01L23/31
Filed: 1989-06-09
Abstract: PURPOSE:To obtain an organic passivation film excellent in reproducibility with no residual stress even if it is large in thickness by a method wherein resin composition is composed of high impurity ball-like silica microparticles whose grain diameters range from 0.01 to 10mum and resin. CONSTITUTION:The grain diameters of high impurity ball-like silica microparticles contained in resin composition used for a passivation film are made to range from 0.01 to 10mum. When ball-like silica particles are smaller than 0.01mum in grain diameter, they are inferior in dispersion when mixed into resin, so that the resin composition are hardly controlled to be excellent in reproducibility of viscosity and thixotropy. When they exceed 10mum in grain diameter, the resin composition can not be formed into a film as thick as adapted for a spin coating method, so that they must not exceed 10mum in grain diameter so as to enable the formed film to meet a required performance in resolution. The thixotropic property concerned is that it is related to the cross-sectional shape and the resolution of a formed film, and when the resin compound is large in thixotropic property, the end of the formed film hardly runs, so that a film uniform in thickness can be obtained when the resin compound is large in thixotropy.
