摘要: A brushless motor control apparatus includes a mask processing unit to which digital induced voltage signal is input, a energizing current timing generation processing unit, a pulse width detection unit, and an advance angle correction unit for performing advance angle correction. The pulse width detection unit measures pulse width of spike voltage, and the advance angle correction unit calculates the correction to the advance angle according to the length of this pulse width. The energizing current timing generation processing unit takes half the value obtained after subtracting the correction value from the edge interval of the position detection signal generated in the mask processing unit as the advance angle.

摘要: A panel with an anti-reflective multi-layered film thereon comprises a glass substrate, an electricity collector for leading static electricity which is formed by baking an electric conductive frit paste on the glass substrate, and has a rough surface, an anti-reflective multi-layered film formed on the glass substrate so as to cover at least a portion of the electricity collector and wherein the film includes an inner electric conductive layer to provide antistatic effect, wherein the thickness of the anti-reflective multi-layered film is less than the maximum height of the surface roughness of the electricity collector, and a lead terminal for earth provided on the outermost layer of the anti-reflective film and above the electricity collector, whereby static electricity produced on the glass substrate with the anti-reflective multi-layered film is collected at the electricity collector through the electric conductive layer so that the static electricity is led to the outside through the lead terminal for earth via the electricity collector.
