A converter for converting serial data streams into parallel data is presented. The device includes a handle and retention structure receivable in an aligning position in the apertures when the slider is in or is moved to its terminal position and engageable with the slider and the stop member to hold the slider in its terminal position so that the user does not have to manually do so during insertion of the lug into the apertures to join the stringers. The configuring is started by a serving GPRS support node that receives an attachment message from a terminal in combination with a subscriber identification that are not known to the serving GPRS support node. A relatively simple signal processing algorithm is used to produce highly effective results with minimal signal distortion. A hook fixing part of the housing mounting member is coupled to the top cowl hook and is formed by the way of drawing in the pressing process. Thus, it allows optimization of in-apparatus the temperature in the apparatus control on error occurrence and temperature control of each inside portion of the apparatus on sheet jam occurrence so as to solve various problems relating to in the apparatus temperature status on the error occurrence.
