    摘要: A sheet feeder stackable in multiple levels and attachable to an image forming apparatus. The sheet feeder includes a drive source, a drive transmission unit, a first drive coupling unit, a second drive coupling unit, a sheet feed roller, and a grip roller. During operation of multiple sheet feeders stacked in the multiple levels, the drive transmission unit and the first drive coupling unit, both provided to a given sheet feeder of the multiple sheet feeders, are coupled to each other, and the first drive coupling unit of the given sheet feeder is coupled to the grip roller of an adjacent sheet feeder disposed immediately below the given sheet feeder to drive the grip roller of each of the multiple sheet feeders substantially in synchrony.

    摘要: An image forming apparatus includes an image forming unit, first and second rotary shafts, a drive source to rotate at a predetermined low velocity and a predetermined high velocity, a first rotary transmitter connected between the drive force and the first rotary shaft, a second rotary transmitter connected between the drive force and the second rotary shaft, and a drive block member connected between the drive source and the second rotary shaft to block transmission of the drive force to the second rotary shaft when the drive source rotates at the predetermined high velocity. When the drive source rotates at the predetermined low velocity, the drive source drives the second rotary shaft using a difference in torque between an upper limit in high velocity rotation and an upper limit in low velocity rotation greater than the upper limit in high velocity rotation.

    摘要: A solvent useful in coal liquefaction is obtained by separating the heavy liquid resulting from coal liquefaction into a fraction boiling at temperatures of between 200.degree. to 210.degree. C., a fraction boiling at temperatures between 211.degree. to 250.degree. C., and a fraction boiling at not less than 250.degree. C., subjecting the fraction boiling at between 211.degree. C. to 250.degree. C. to two hydrogenation treatments, mixing the hydrogenated product with the fraction boiling at between 200.degree. to 210.degree. C. which optionally has been hydrogenated to form a resultant mixture and mixing a portion of the resultant mixture with the fraction boiling at not less than 250.degree. C. which has been optionally hydrogenated.
