Title: Television receiver
Inventor: IKEDA YASUNARI
IPC: H04N5/44
Filed: 1983-03-11
Abstract: PURPOSE:To eliminate flickering and to decrease disturbance of dual image by utilizing a video signal of the preceding field (a signal delayed by (n) and (n+1) horizontal period) so as to obtain a luminance signal of the non-interlace system where the luminance responses of an odd and an even number fields are equal. CONSTITUTION:In figure, thin lines indicate white level and thick lines show black level. Signals of a scanning line of the odd and the even number fields of video signals Sia and Sib obtained from level adjusting devices 17 and 19 are shown in Figs. B and C. In these figures, dual lines indicate intermediate level. Thus, the signal of the scanning line of the odd and the even number fields of a video signal Siab of the non-interlace system from a changeover switch 12 of a converter 18 is identical to each other as shown in Fig. D. The scanning is performed respectively as shown in scanning lines 1, 2- and 2', 3'- in the odd and the even number fields. Since the change in the luminance response of the odd and even number fields of the video signal Siab is the same in this way, flickering due to line flicker is not caused. Since the signals Sia and Sib averaging the video signal Si on the preceding and present scanning lines are used, dual image disturbance is decreased.

IPC: B41J17/02
Filed: 1994-03-11
Abstract: PURPOSE:To properly feed printing paper even at the time of low temp. while keeping a printer itself small-sized. CONSTITUTION:A CPU 44 controls the feed speed of printing paper on the basis of temp. data TH due to a temp. sensor 40 detecting the temp. in a thermal transfer color printer. For example, when the temp. data TH is lower than a predetermined value, the feed speed of the printing paper is reduced to half.

Title: Sheet curl correcting device
Inventor: TANEDA KENGO
IPC: B65H23/34
Filed: 1983-03-14
Abstract: PURPOSE:To allow a sheet cntainer to receive curled sheets after transcription with high efficiency by permitting each sheet to travel between a feed belt and a correction shaft, applying a specific pressure partially to the sheet according to the shape of each proceduced curl, and thereby correcting the curl. CONSTITUTION:A transcript sheet P exhausted from a fixation roller 21 depresses a pin plunger 28, so that a control circuit 27 commences clocking. The sheet traveling thereafter together with a feed belt 25 passes through this feed belt 25 and a correction shaft 29, wherein the clock is within a preset time to provide less friction force likely to be applied to the sheet P, so that no significant correction is made to the sheet P. When the portion of sheet which requires a curl correction comes up to the part between the feed belt 25 and correction shaft 29, i.e. if the clocking by said control circuit 27 exceeds the preset time, so the control circuit 27 energizes immediately a solenoid 35 for a certain specific period of time to cause detection of a pin 36 with a stopper 38, and now the correction shaft 29 will stop to enlarge the friction force applied to the sheet P. Thus the curl of the sheet is corrected to ensure efficient reception of sheets by a tray 33.
