    摘要: A high strength steel pipe for an airbag system has a steel composition comprising C: 0.05-0.20%, Si: 0.1-1.0%, P: at most 0.025%, S: at most 0.010%, Cr: 0.05-1.0%, Al: at most 0.10%, at least one of Ti and Mn satisfying (1) Ti≦0.02% and (2) 0.4%≦Mn+40Ti≦1.2%, and a remainder of Fe. The composition may further include one or more of (i) at least one of Mo: 0.05-0.50%, Ni: 0.05-1.5%, V: 0.01-0.2%, and B: 0.0003-0.005%, (ii) at least one of Cu: 0.05-0.5% and Nb: 0.003-0.1%, and (iii) at least one of Ca: 0.0003-0.01%, Mg: 0.0003-0.01%, and REM: 0.0003-0.01%. The steel pipe can be manufactured by forming a pipe from the above-described steel composition to obtain prescribed dimensions, heating to at least the Ac1 transformation point and quenching, and then tempering at the Ac1 transformation point or below.

    摘要: A lubricant applicator includes a solid mold lubricant, a lubricant application roller, and a flicker member. The lubricant application roller scrapes and applies the lubricant to an image bearing member. The flicker member removes a powder substance adhered to the surface of the lubricant application roller and is disposed upstream of the solid mold lubricant in a direction of rotation of the lubricant application roller. The lubricant application roller, the flicker member, and the solid mold lubricant define a sealed space therebetween. A lubricant applicator includes the solid mold lubricant, the lubricant application roller, the flicker member, and an adherence prevention member that prevents the substance removed by the flicker member from adhering again to the lubricant application roller. A lubricant applicator includes the solid mold lubricant, the lubricant application roller, and a lubricant receiver that receives the scraped lubricant from the lubricant application roller.
