摘要： Firstly, in order to check the noise level of a device, DC erasure is applied to a magnetic recording medium and the magnetic recording medium is read. Then, a test signal including a first order component and a third order harmonic frequency is written into the magnetic recording medium. The written test signal is read and Fourier transform is applied to the read signal to obtain the respective amplitude of the first order and third order harmonic components. Then, it is determined whether the amplitude of the third order harmonic component is sufficiently large compared with the obtained noise level. If the amplitude is sufficiently large, the flying height of the head is estimated using both the first order and third order harmonic components. If the amplitude is not sufficiently large, the flying height of the head is estimated using only the first order component.

摘要： This invention relates to a process for preparing high-purity aromatic oligomers by effectively separating an organic layer containing aromatic oligomers or the reaction products of a polycyclic aromatic compound with formaldehyde from an aqueous layer containing an acid catalyst in a simplified manner, hitherto regarded difficult to accomplish, and obtaining high-purity aromatic oligomers from the organic layer containing a reduced amount of impurities. In separating the aqueous layer containing the acid catalyst and the organic layer containing the oligomers from the reaction mixture formed by the condensation of a polycyclic aromatic compound and formaldehyde, the emulsion phase is broken by adding a nonionic or cationic surfactant in an effective amount and an alkali in an amount sufficient to neutralize 1–70% of the acid in the acid catalyst, the organic and aqueous layers are separated and the aromatic oligomers are recovered from the organic layer.

摘要： A method of electroplating using a photoresist layer on a conductive seed layer. The photoresist layer defines a column-shaped space. Ridges are formed on the wall surfaces of the photoresist layer surrounding the column-shaped space. The ridges extend from the conductive seed layer to the opening of the column-shaped space. The electrolytic solution drives bubbles out of the column-shaped space, so that the column-shaped space is filled with the electrolytic solution without any cavities. In addition, if hydrogen bubbles are generated in the column-shaped space, the electrolytic solution serves to drive the hydrogen bubbles out of the column-shaped space along the corners of the column-shaped space.

摘要： A magnetic disk storage apparatus comprising a rotary actuator which prevents head positioning error resulting from vibration and impact. Since head positioning error is generated when the enclosure makes rotating movement due to translational vibration input due to vibration, a vibration proof mechanism consisting of a plurality of vibration proof supporting members are provided between the enclosure and frame. The plural vibration proof supporting members are disposed so that the linear moment around the gravity center of the enclosure is balanced against translational external force applied to the enclosure.
