Title: Recorder
Inventor: TAKAHASHI YUUJI
IPC: B65H9/14
Filed: 1982-02-25
Abstract: PURPOSE:To transfer to another place a recording sheet which is in the condition of skewing or jamming, by a method wherein the skew quantity of a recording sheet fed from a storing part for the sheet is detected, and control of the feed of the recording sheet is varied in accordance with the skew quantity. CONSTITUTION:When one of sheets 31 of paper stacked on a paper-supplying stage 30 is delivered into a feeding passage by a paper-supplying roller 32, skewing generated at the time of the paper-supplying opeation is corrected by a pair of resist rollers 33, and the leading end of the sheet 31 of paper is adjusted. While the sheet 31 passed between the resist rollers 33 passes through a feeding guide 34 (constituting a part of the feeding passage) before coming into contact with a photo-sensitive drum 14, a skew-detecting sensor 47 discrimiates whether or not a skew is present. The presence or absence of jamming is detected by a photo-sensor 35 placed between the drum 14 and a feeding belt 39. The recroding paper in the condition of skewing or jamming is discharged onto the second output tray 46 by controlling a paper discharge change-over solenoid.

Abstract: PURPOSE:To set the flash amt. after forging a forged part in a constant amt. always irrespective of the increase and decrease of the die wear amt. of a forging die by controlling so as to vary the weight of the billet to be forged of the following time based on the measuring information of the die wear amt. of the forging die after forging a metal billet. CONSTITUTION:The weight of a crank shaft W3 after trimming is weighed 12 in case of forging a crank shaft as for the engine part of the vehicle of an automobile, etc., for instance. The flash amt. after forging a shaft W3 is set in a constant amt. irrespective of the increase and decrease of the die wear amt. of a forging die by controlling the cutting dimension (weight) of the metal billet W2 to be forged of the following time based on this measured value. The cost is thus reduced by constraining the increase of said flash amt. even in case of the number of forgings being less, for instance. The die service life can be extended by constraining the resistance increase of the flash land of the forging die against the billet W2. Moreover, the heating energy necessary for the warm forging of the billet W2 in case of a warm forging for instance can be reduced.
