A first electronic component having two alignment holes perforated at predetermined positions thereof at a predetermined interval is held with a receiving table, and also a second electronic component having two alignment marks formed at predetermined positions thereon at an interval therebetween in agreement with that between the two alignment holes is held with a position-adjusting mechanism. Upper ring and base members are locked together by peripheral post members, forming an upright rigid framework that operatively supports a woven fabric bulk material receiving sleeve. The high frequency portion is so disposed on, and electrically connected to, the low frequency portion so as to allow the orientation-insensitive ultra-wideband coupling capacitor to work identically when mounted on any external longitudinal surface of the plurality of external surfaces thereof and thereby be readily SMT compatible without regard to special orienting procedures. As long as the digital signal values are less than DRV, the seek process continues. The light emitted by the LED light sources of an LED module is irradiated directly onto the lens and is projected therefrom into the outside space. The chamber is preferably filled with a foam material and is further in communication with ambient air to enable mixing with expired air within the chamber.
