Title: Control method of printer controller
Inventor: OGUSURI YUJI
IPC: B41J29/38
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To complete printing as user's requests even if trouble occurs by placing a recovery printing notification means in operation when there are undischarged sheets of paper in case of a fault occurring to an output device during the printing and the output device becomes ready for the printing after the trouble is removed. SOLUTION: The printer controller 1 checks whether or not there are sheets of paper as a candidate for recovery printing among pages having had image data transferred to an output device 5 by an output controller 4 and the pages left in print data storage devices 3. After the output device 5 having the trouble removed becomes ready for the printing again, the printer controller 2 stops the printing until a recovery printing notification means 9 gives notice of a state wherein the recovery printing is possible to the outside. Once recovery printing execution is selected, the data are sent from the print data storage devices 3 to the controller 4 and the output controller 4 outputs the expanded image data to the output device 5, so that the recovery printing is carried out.

Title: Carrying device and paper feeder
Inventor: TANIYAMA RYOJI
IPC: B65H9/14
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent carrying failure and a jam of a paper sheet by controlling a rotating speed of a carrying means according to a variation in a carrying load. SOLUTION: A paper feeding roller 9 is installed on one end of a differential mechanism, and a torque limiter 21 is installed in the other end part. When a load of a paper feeding roller 9 reduces more than a preset load by the torque limiter 21, a rotating speed of the paper feeding roller 9 increases as shown by an expression [a rotating speed 1 ÷ a load (a torque limiter) + a rotating speed 2 ÷ a load (a paper feeding roller) = 2 × an input rotating speed], and a paper sheet uniformly contacts with a regist roller, and reaches a preset deflection quantity of the paper sheet, and when a load of the paper feeding roller 9 increases, a rotating speed of the paper feeding roller 9 reduces or stops.  The rotating speed is changed to two times from 0 to a load change by presetting a load of the torque limiter 21 as shown by the expression, and a deflection quantity of the paper sheet is kept constant. Therefore, carrying failure, a paper jam and a stain by a slip can be prevented.

Filed: 1985-11-08
Abstract: PURPOSE:To improve the efficiency of a switching circuit by mounting a saturable reactor in order to feed back load fluctuation on the secondary side to a drive transistor. CONSTITUTION:A switching power circuit is constituted by connecting a converter transformer 8 to a switching Tr 9 for a horizontal drive circuit 11 consisting of a drive transformer 7, a drive transistor (hereinafter called Tr) 10, etc., and rectifies 3 a secondary-side output from the transformer 8 and supplies load with the output. In this case, a saturable reactor 15 is connected in series with the drive Tr 10, and a secondary winding for the reactor 15 is connected between the load and a ground. Consequently, when load is reduced, load currents are also minimized, and the inductance of the primary side of the saturable reactor 15 is increased. Accordingly, the currents of the drive Tr 10 are decreased, and the drive of the switching Tr 9 is lowered. When load is increased, the switching power circuit reversely operates.
