An apparatus that adaptively allocates transmission power for beam-forming combined with orthogonal space time block codes in a distributed wireless communication system, the apparatus including: sub-arrays for beam-forming, which are geographically distributed and each of which includes a plurality of distributed antennas placed in random groups. A releasing knob, operated for returning the control lever from the operating position B to the releasing position A, is disposed on a side face of a grip of the control lever, the side face corresponding to an opened face of the recess, so that the gap g between an inner wall of the recess and a head of the grip can be narrowed without being interfered with by the releasing knob. The mask layer and the quartz layer are dry etched through a photoresist layer that has been applied over the chromium layer and patterned according to an alternating PSM design. A display section is provided on the case for transmitting the light, radiated from the light source, to be visually checked on the external side. For detection of fungal DNA, at least one segment of the fungal DNA to be detected is amplified, then the amplification products are detected. The device has a motor that drives a motor linkage, which includes a push rod that has one end that engages and moves a dental cleaning head about a center pin to cause an oscillation motion of the head.
