Title: Recording disk substrate and production thereof
Inventor: MORISANE TOSHITOMO
IPC: C03C15/00
Filed: 1989-02-16
Abstract: PURPOSE:To readily obtain the title substrate holding a high-density recording medium by crystallization treatment of a specific crystal glass-contg. substrate followed by abrasion and by treatment with an etchant with etching rate for crystal layer differing from that for amorphous one. CONSTITUTION:A substrate containing SiO2-Li2O-Al2O3 based crystallized glass is put to crystallization treatment followed by abrasion and then treatment with an etchant with etching rate for crystal layer differing from that for amorphous one, thus obtaining the objective recording disk substrate. For said crystallized glass, its surface has been abrasion-treated and its fine structure is such that fine, homogeneous crystal grains are regularly, uniformly and two- dimensionally distributed in the amorphous layer. As the surface of the present substrate has the fine structure, an air turbulence is produced on the surface by the rotation of the disk substrate, acting as a buoyant resistance against a magnetic head. Thereby the magnetic head will keep at a aluminum distance from the substrate surface without causing any magnetic head crush.

Abstract: PURPOSE:To set the neutral point potential of a load to 0 by adding power control outputs of 3-phases, and subtracting the signal divided by 3 from the added value by the current control output of each phase as a 3-phase voltage command value. CONSTITUTION:A DC power source 1 is supplied as 3-phase AC powers of variable frequency and variable voltage through an inverter 2 for PWM (pulse width modulation) controlling to an AC motor 3. The currents iu-iw of the phases are respectively detected by current detectors 4V-4W, deviations to the current command values of the phases are calculated by a calculator 5, and the voltage command value of the inverter 2 is output. In this case, an adder 11, a coefficient unit 12 and a subtractor 13 are added. Thus, the outputs of amplifiers 6 are added, divided by 3 by the unit 12, and subtracted. Thus, if a negative DC component is contained, for example, in the detected current iu of the phase U, the output of the current control of phase U tends to shift by DELTAvu to the positive side, but the sum of the voltage command values of 3 phases is always set to 0, and controlled so that the neutral point potential of the motor 3 becomes always 0.
