    摘要: A panel-shaped gas-discharging type display device includes an anode and a cathode having a special shape to enhance discharging in an airtight chamber formed by two substrates. A gas containing an ultraviolet emission gas such as Xe and Kr and a fluophor for emitting a light are put together into the airtight chamber. Because of the shape of the cathode, more discharging occurs than with conventional devices. More ultraviolet emission from the discharging excites the fluophor to create a visible radiation. Therefore, the brightness of the device increases. Since the cathode is coated with an emitter material incapable of absorbing the ultraviolet emission gas, discharging is not obstructed by reduction of the ultraviolet emission gas, and the color of the visible radiation is stably maintained.

    摘要: The present invention provides a micro stepping motor for more accurately stepping and positioning a magnetic head in a magnetic disc system. The stepping motor has a permanent magnet type rotor and a stator encircling the rotor, the rotor having a plurality of pole teeth formed therein with a fine pitch and the stator also having a plurality of pole teeth formed therein with a fine pitch and disposed opposed to the pole teeth in the rotor, the stator pole teeth being divided into at least one pair of pole tooth groups which are out of phase relative to each other by an electrical angle of 180 degrees. A single common stator coil is provided to the pair of stator pole tooth groups. Thus, the stepping pitch of the rotor is determined by the pitch in the pole tooth groups, whereby the rotor can steppingly be driven with higher density even by the reduced number of stator coils. In addition, plural pairs of pole tooth groups can be formed such that at least two pairs of pole tooth groups and the corresponding two stator coils will be provided to determine the stepping angle of the rotor optionally under the multi-excitation.

The pulse width of the second alternating current pulses is selected to be smaller than that of the normal driving pulses.
