A motor apparatus is constructed to compensate for a delay in operation of the motor apparatus, so that the efficiency is improved and noise is reduced over a broad motor rpm range by driving the motor at the optimum timing. The motor driving control circuit of the motor apparatus includes a phase adjustment circuit which inputs signals of the U phase, V phase and W phase output by rotational position signal amplifiers, and performs an adjustment for the respective signals so that the phases are arbitrarily advanced by a ratio corresponding to phase adjustment voltages, an automatic gain control circuit which inputs the output signals of this circuit and the gain of which is feedback-controlled according to the driving currents of the armature coils of the motor, an FG circuit which produces a periodic pulse train from the rotational position signals, and a frequency-voltage conversion circuit which performs a conversion to a voltage corresponding to the frequency of the pulse train, and outputs the converted voltage as a phase adjustment voltage.

In the manufacture of a striped phosphor screen for a black matrix type color picture tube, a pattern of stripes of a light-absorbing material is first formed on the faceplate of a glass envelope to define transparent striped windows thereon by a known process and then phosphor materials are applied to the striped windows by the use of a nozzle assembly having at least one nozzle capable of discharging a phosphor material, without owing to the photolighography. The coating apparatus comprises a nozzle assembly including one or more nozzles, drivers for effecting relative movement between the nozzle and the faceplate of the glass envelope in a first direction in the plane of the faceplate and perpendicular to the stripes, in a third direction perpendicular to the faceplate and in a second direction longitudinal of the stripes, sensors for detecting the position of the nozzle, generators for producing a positional error signal and control for controlling the position of the nozzle.
