摘要： A control apparatus for an internal combustion engine can detect knocking of the engine even when an extraction frequency band is switched in accordance with an operating state of the engine. The apparatus includes a knock sensor for detecting vibrations generated in the engine and outputting a vibration detection signal, a rotation sensor for detecting the engine operating state, a SCF circuit for extracting a signal of a specific frequency band from the vibration detection signal and outputting an extracted vibration signal, a filter frequency switching section for switching an extraction frequency band of the filter section in accordance with the engine operating state, and a knocking detection section for detecting knocking of the engine based on the extracted vibration signal. The filter frequency switching section inhibits switching of the extraction frequency band until a switching inhibition period elapses after the switching of the extraction frequency band.

摘要： A magnetic recording medium having high bonding capability between the surface lubricant and the diamond-like carbon (DLC) protective layer in the surface of the magnetic recording medium is disclosed. The lubricant is a fluorine-containing lubricant for magnetic recording media represented by the following formula (1), (2) or (3), wherein the substituents R1, R2, R3, R4, R5 and R6 in the terminal part of the lubricant each independently represent an organic group, and at least one of the substituents R1 and R2, at least one of the substituents R3 and R4, and at least one of the substituents R5 and R6 each have an isocyanate group: Also disclosed is a magnetic recording medium using the lubricant.
摘要翻译：公开了一种在磁记录介质表面的表面润滑剂和类金刚石碳（DLC）保护层之间具有高结合能力的磁记录介质。润滑剂是由下式（1），（2）或（3）表示的用于磁记录介质的含氟润滑剂，其中润滑剂末端部分中的取代基R1，R2，R3，R4，R5和R6 各自独立地表示有机基团，并且取代基R 1和R 2中的至少一个，取代基R 3和R 4中的至少一个以及至少一个取代基R 5和R 6各自具有异氰酸酯基团。还公开了磁记录介质使用润滑剂。
