摘要： Embodiments of the present invention help to compute controlling quantity to make the spacing between a floating head slider and a recording medium optimum without damaging the floating head slider and the recording medium by detecting the floating head slider's contact with the recording medium with high sensitivity. According to one embodiment, when the floating head slider is floating over the magnetic disk, a controller takes samples of a notable characteristic value (amplitude) from signals reproduced by a reproducing head, retains the variation of the sample amplitude as a reference signal, takes samples of amplitude from signals reproduced by the reproducing head while reducing the spacing between the floating head slider and the magnetic disk gradually, produces a signal which is the sample signal from which the reference signal is subtracted, detects the floating head slider's contact with the magnetic disk when the fluctuation of the signal so produced exceeds a reference value and, on the basis of a fly-height-control mechanism's controlling quantity at the time of the contact, computes the controlling quantity for making the spacing between the floating head slider and the magnetic disk optimum.

摘要： This invention relates to a denitrifying composition which is a material to be used for decomposing nitrates nitrogen in effluent by sulfur-oxidizing bacteria that consume sulfur and carbonate as nutrients and is characterized by containing particles of calcium carbonate dispersed in sulfur. Preferably, the composition contains 10 parts by weight of sulfur coexisting with 10-15 parts by weight of calcium carbonate and 1-3 parts by weight of a microporous substance. This denitrifying composition can be prepared by heating powder of calcium carbonate and sulfur thereby melting the sulfur, dispersing the powder of calcium carbonate in liquid sulfur and solidifying the dispersion by rapid cooling. The composition simultaneously contains nutrients and alkali source and hence enables denitrification to proceed stably without addition of other components.
摘要翻译：本发明涉及一种反硝化组合物，其是用于通过硫氧化细菌将硫酸和碳酸盐作为营养物质分解出来的硝酸盐氮的材料，其特征在于含有分散在硫中的碳酸钙颗粒。优选地，组合物含有10重量份与10-15重量份碳酸钙共存的硫和1-3重量份微孔物质。该反硝化组合物可以通过加热碳酸钙和硫的粉末来制备，从而熔化硫，将碳酸钙粉末分散在液体硫中并通过快速冷却固化分散体。组合物同时含有营养物和碱源，因此使得脱氮能够稳定地进行而不添加其它组分。

摘要： Embodiments of the present invention provide a process that monitors a magnetic playback signal while gradually increasing an electricity supply amount for a heater to thereby determine contact between a magnetic head slider and a magnetic disk medium. According to one embodiment, after components for configuring a magnetic recording/playback portion are assembled into a housing, magnetic information is played back on a specific track of a magnetic disk medium by using a playback element while gradually increasing an electricity supply amount for a heater of a magnetic head slider. An amplitude of a playback signal is measured at a plurality of portions along a circumferential direction of the track. Contact between the magnetic head slider and the magnetic disk medium is detected in accordance with an increase in variation in the measured amplitude. Then, a value obtained by subtracting an predetermined value of an electricity amount from an electricity amount in the event of detection of the contact is stored (set) as an appropriate electricity amount for the magnetic head slider into a storage portion.
