Title: Light beam scanning lens
Inventor: NAGATA SHINICHI
IPC: G02B26/10
Filed: 1987-04-27
Abstract: PURPOSE:To straighten a scanning locus even in case of a beam incident from the outside of a deflecting surface by constituting a lens system of a first lens group having a negative focal length and a second lens group having a positive focal length in order from the deflecting means side and specifying the coefficient of the third-order distortional aberration. CONSTITUTION:The lens system consists of the first lens group having a negative focal length and the second lens group having a positive focal length in order from the deflecting means side, and a coefficient V of the third-order distortional aberration is set to one or a value approximating one to provide the lens system with such characteristic that the distance between the projection point of the light beam projected on a surface to be scanned and the optical axis is proportional to the sine of the angle between the light beam and the optical axis at the deflection point. Since the scanning locus is straight even if the light beam is made incident from the outside of the deflecting surface, it is unnecessary to exactly match the deflecting surface of the light beam to the optical axis of lenses, and adjustment is facilitated.

Title: Ink ribbon cassette
Inventor: SHIMOYAMA NOBORU
IPC: B41J33/26
Filed: 1987-04-25
Abstract: PURPOSE:To reduce the strength of a ribbon cassette, to make the travel of a take-up spool smooth, and to reduce the change in a ribbon feed amount due to the change in a ribbon take-up diameter, by a method wherein, a take-up lever is rotatably held to a lower case, and the take-up lever is pressed to be rotated by the force of a tension coil spring wit a small spring constant. CONSTITUTION:The engaging force between a feed gear and a take-up spool 61 is imparted by a tension coil spring 47. Therefore, a take-up lever 44 is always pressed in a direction E, and a ribbon on the spool 61 is taken up in a direction H due to the force of the feed gear. The increase of a ribbon take-up amount around the take-up spool 61 causes the take-up lever 44 to rotate reverse to the direction E. As the coil spring 47, a spring of a small spring constant can be used. Therefore, the strength of a cassette is allowed be lowered, and also the travel of the take-up spool 61 is smoothened. Moreover, the feed gear is pressed into the ribbon by a small amount as a whole with a remarkably low increase ratio. In this manner, the pressing force acting between the take-up spool 61 and the feed gear is nearly uniformized, and the change in a ribbon feed amount is made remarkably smaller than that in a ribbon take-up amount around the spool 61.

Title: Method for controlling continuous rolling
Inventor: SUEHIRO KATSUMI
IPC: B21B37/00
Filed: 1985-05-15
Abstract: PURPOSE:To improve the accuracy of sheet thickness control during the change of sheet thickness and the stability of a rolling operation by executing continuously the sheet thickness control and tension control to preset values at the point of the time when the thickness change point of a sheet material arrives at a prescribed point then changing the rolling down position and roll circumferential speed of a rolling stand. CONSTITUTION:The target sheet thickness value on the outlet side of the Noi stand determined preliminarily for a sheet thickness control device (AGC) of the Noi stand is changed from HAi to HBi at the point of the time when the sheet thickness change point arrives at the Noi stand in, for example, a 4-stand cold tandem rolling mill. The target tension value between the Noi stand and Noi+1 stand predetermined for a tension control device (ATC) between the Noi stand and Noi+1 stand is changed from TA1 to TB1 at the point of the time when the sheet thickness change point arrives at the Noi stand or the prescribed position between the Noi stand and Noi+1 stand. The sheet thickness control and tension control are thus continuously executed even during the sheet thickness change, by which the sheet thickness is changed.
