The sensing electrode and the shield grid electrode are connected to the evaluating circuit and the shield grid electrode is subjected to an alternating voltage.
This is achieved by embedding the multipoint emission cathode in a free-floating shield grid.
The detector detects the information of the second pattern by detecting the X-rays from the shield grid.
Holes on the speaker mesh (1) gradually increase in size from the inside going outwards.
Preferably, the mouth guard (4) is detachable.
The sound mesh (1) is circular.
Because the speaker mesh (1) is provided thereon with the reinforced bars (2), the strength of the speaker mesh (1) is increased, preventing same from being damaged easily, particularly the middle portion.
The speaker mesh (1) and the upper housing are connected; the speaker mesh (1) is provided thereon with reinforced bars (2).
A conveying apparatus (5) is arranged at the lower end of the barrier mesh (4).
The present invention obviates the speaker mesh, and provides sound holes directly on the sound box upper housing, thus allowing not only for increased assembly speed, but also for conserved materials and for reduced costs.
The guard ring may include first, second, and third regions.
The outdoor unit has an outdoor fan, an air blowout opening, and the fan guard (30).
The present invention discloses a leaf snatcher consisting of a protective grille, a blade activated by a motor.
The tilt adjuster (10) is preferably assembled with a speaker cover (18).
A reticulate cover is provided at an end of the cylinder-like body, and a front cap is provided on the other end.
The spacer is integrally welded with the protective grid in a single arranging and welding operation.
A dielectric layer (6) extends over the electrodes (4) over which there is a screening electrode (7) with an aperture (8) for each of the electrodes (4).
A guard ring may surround the functional circuitry to isolate the circuitry from the noise sources.
The speaker mesh (1) and the sound box upper housing are connected.
A barrier mesh (4) is arranged at the lower end of the inner side of the machine frame (1).
The invention relates to a side guard mesh comprising at least one wire mesh (2) comprising longitudinal bars (3) and transverse bars (4), and an outer frame (7) bounding the wire mesh (2).
