摘要:
A porous membrane with pores that includes a polymerization product of a polyazole-based material, an electrolyte membrane including the porous membrane with a proton-conductive polymer provided in pores of the porous membrane, methods of manufacturing the porous membrane and the electrolyte membrane, and a fuel cell employing at least one of the porous membrane and the electrolyte membrane.
摘要:
A photoreceptor belt control apparatus for a printer designed to correct lateral traveling of a photoreceptor belt traveling by being supported by rollers rotatably installed on a belt frame (100), and/or to control tension for the photoreceptor belt. The apparatus includes an auxiliary frame comprising a pair of auxiliary frame members (51, 55) slidably and pivotally installed on the belt frame (100), a steering roller (61) whose ends are rotatably installed respectively on the auxiliary frame, the steering roller (61) rotating in contact with the photoreceptor belt, a shaft (65) whose ends are rotatably installed on the belt frame (100), a cam unit (70) installed on at least one end of the shaft (65) for controlling the inclination of the steering roller (61) by pivoting each of the auxiliary frame members (51, 55) according to the rotation position of the shaft (65), and a tension control unit (80) for controlling tension to be applied to the photoreceptor belt by sliding the pair of auxiliary frame members (51, 55).
摘要:
A photoreceptor belt steering apparatus for a printer comprises a guide roller (131) for guiding the circulation of a photoreceptor belt (100); and one or more steering rollers (140) arranged on a common shaft (120) next to the guide roller (131) at a predetermined tilt angle with respect to the outer circumferential direction of the shaft. The steering rollers correct a lateral slip of the photoreceptor belt by changing their inclination direction according to a pivot angle of the shaft. A driving unit installed between a frame (110) and the shaft (120), controls the degree of pivot of the shaft (120), thereby controlling the tilt angle of the steering rollers (140).
