The present invention relates to a gas separation membrane comprising as a main component a polyacetal, wherein the polyacetal contains 1. When the manual feed tray is opened, the use is assumed to be about to use the image forming device, and thus energy conservation becomes possible because the specific power is turned on only at this time. The needle bar is mounted for reciprocation and for lateral movement relative to the direction of reciprocation by a drive system including a first directional drive component having a foot secured to a respective push rod of the tufting machine and a second directional drive component connected to the shift mechanism. The compositions of the invention are substantially free of metal oxides and sulfur, and do not require harsh oxidative treatments. At the first end, the aperture has a first inner diameter that is slightly greater than the outer diameter of the shaft at the distal end, the aperture tapers to a second inner diameter which is approximately the diameter of the shaft. According to the present invention, the storage means, or condom card, comprises two separable half portions each containing a storage compartment for storing at least one condom therein.
