IPC: G11B5/72
Filed: 1986-03-13
Abstract: PURPOSE:To obtain substantial wear resistance and corrosion resistance and to eliminate the need for a lubricating layer by providing a silica layer and molybdenum disulfide layer on a magnetic layer formed on a substrate. CONSTITUTION:A protective film is constituted of the silica layer 3 having good mechanical characteristics and the molybdenum disulfide layer 4 having good lubricity. The wear by a magnetic head is, therefore, decreased and a CSS (contact start stop) characteristic is improved. Since the silica layer 3 of the lower layer has the good adhesiveness of the magnetic layer 2 and wettability therewith, the corrosion resistance is largely improved and the corrosion, etc., of the magnetic layer 2 are surely prevented. The silica layer 3 and the molybdenum disulfide layer 4 are continuously formed within the same chamber by sputtering. The adhesiveness of the silica layer 3 and the molybdenum disulfide layer 4 is thereby improved and the protective function as the protective film is improved.

Title: Detecting device of extraordinary noise of gear
Inventor: FUKADA KOUICHI
IPC: G01M13/02
Filed: 1983-03-29
Abstract: PURPOSE:To monitor the breakage of a tooth surface without fail and with high reliability by a method wherein extraordinary noise generated intermittently due to the breakage of a tooth or the like is extracted through a band-pass filter, and only a specific frequency is converted into a pulse waveform and counted. CONSTITUTION:When any breakage of a tooth surface occurs in a gear unit 1 to be tested, detected noise, which is detected by a microphone 4, shows an extraordinary peak value characteristic intermittently as a fluctuation in sound pressure. From a signal of the extraordinary peak value characteristic, a fundamental wave frequency fO of the noise caused by an engagement of a gear to be monitored is extracted by a subsequent band-pass filter 32, and then is transmitted to a rectifier 33 for detecting a sound pressure level, in which a DC output voltage proportional to the sound pressure level is obtained. Next, a signal of the DC output voltage is passed through a differentiator 34, and thereby only a portion equivalent to the sound pressure level of extraordinary noise generated intermittently is taken out. Then, an output signal of the differentiator 34 is subjected to pulse conversion by a wave-shaping unit 35, and a pulse thus obtained is inputted to a pulse counter 36, in which the number of output pulses is counted. Thereby the state of occurrence of the intermittent extraordinary noise is known quantitatively and determined for monitoring the breakage of the tooth surface.
