Title: Method for removing particulate deposited on burnishing head
Inventor: MORI KYOICHI
IPC: G11B5/84
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To effectively remove aggregated particulates of a lubricant deposited on a vanishing head while projections are burnished. SOLUTION: During a burnishing head 3 moves forward, the circumferential speed of a magnetic disk 1 to the head 3 is made constant and projections t are burnished with a fixed floating height Δh. During the head 3 moves backward, the disk is rotated at a fixed angular speed. Thereby, the circumferential speed to the head 3 is increased proportionally to the radius of the disk 1 and the floating height Δh is gradually increased so that aggregated particulates F deposited on the head during moving forward is removed by being distributed again on the surface of the disk 1. Therefore, the burnishing head 3 can be reused.

Title: Protective apparatus for recording head
Inventor: MEN SHINICHI
IPC: G06K15/00
Filed: 1986-09-19
Abstract: PURPOSE:To prevent a recording head from being driven by a heat pulse having a predetermined width or wider by driving a logic voltage monitor, a head drive inhibitor and a head driver by a backup voltage. CONSTITUTION:Switching transistor circuits Tr1, Tr2 turn ON, OFF a head voltage VH to drive a recording head 9 through a drive circuit 13. A backup circuit 28-4 outputs a backup voltage VDDH to a logic voltage monitor 29-1, a head drive inhibitor 29-2 and a head driver 13 to drive them. When a head voltage VH is turned OFF, it proves the voltage VDDH until a capacitor is completely discharged, it drives the inhibitor 29-2 thereby stopping the application of a heat voltage to the head 9, and proves a heat inhibition by the monitor 29-1. Thus, even if a heat pulse width is erroneously applied in a predetermined width or wider, it can prevent an excess power from being applied to the head to protect it against a damage.

Title: Inverter modulation system
Inventor: KOO HIDEO
IPC: H02M7/48
Filed: 1982-12-15
Abstract: PURPOSE:To maintain the output waveform of a pulse output power laterally symmetrical and to enable to obtain the minimum ON/OFF time by adding a rectangular wave signal so that a comparison signal sliced by a modulation signal to the triangular wave signal of a carrier may not be shortened to the prescribed minimum width or lower. CONSTITUTION:A carrier signal generator 35 is provided to generate a composite waveform signal so that the rectangular wave pulse waveform signal is superposed not on mere triangular signal but on the upper minimum width part to a triangular wave signal. When the comparison of the carrier of the composite waveform signal with the modulation signal is performed by a comparator 22, it is limited so that the pulse width of the resultant gate signal may not become smaller than the minimum ON/OFF period. Further, no displacement occurs in the pulse waveform of the gate signal, but since the OFF period of the interphase output signal waveform can be accurately set in advance, the output signal waveform can obtain 3-pulse output signal waveforms which are completely lateral symmetrical.
