Title: Image forming device
Inventor: YAMAGUCHI YUKUO
IPC: G03G15/00
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the paper wrinkles of a sheet material by shifting the position in a height direction with respect to a nip part, of a guiding member, so as to make the size of the loop of the sheet material formed before the nip part changeable at the arbitrary position of the sheet material. SOLUTION: An approach guide 20 is turned counterclockwise by the repulsion of a tension spring 32 caught in a hole 20b and stops turning at the position where a projection 20d and a fixing plate 35 are abutted. At this time, an approach guide top end part 20a becomes a low position state as the position where the sheet material enters into the nip part, from the position near the extension direction of the nip part N. When a solenoid 33 engaged with the oblong hole 20e of the guide 20 is turned on and a plunger is drawn, the guide 20 is turned and stops turning at the position where a projection 20c and a fixing plate 34 are abutted. At this time, the approach guide top end part 20a becomes a high position state as the position where the sheet material enters into the nip part, from the position away from the extension direction of the nip part N.

Title: Vertical contour correcting device
Inventor: MURAKAMI AKIHIDE
IPC: H04N9/68
Filed: 1992-01-31
Abstract: PURPOSE:To obtain a sharp picture by reducing dot disturbance without deteriorating the vertical resolution of a luminance signal. CONSTITUTION:A contour component resulting from a subtraction processing between an input signal and a signal after being delayed by 11 horizontal scanning periods passes through a filter 6 in the vertical contour correction device in which one delay element 1 is employed to add simultaneously overshoot and preshoot to the vertical contour for one horizontal period. Then the output of the filter 6 is inputted to a coring level control voltage detection circuit 8. When a chroma component is not sufficiently eliminated in the output of the filter 6, the mixing of the chroma component to the luminance signal is prevented and dot disturbance is reduced.

Abstract: PURPOSE:To decrease the fluctuation of the mixing ratio of solvents even with a small mixer of a device for feeding the solvents to the mixer by plural units of reciprocating pump by providing constant-pressure valves between the mixer and the respective reciprocating pumps. CONSTITUTION:The solvents 3, 4 are respectively fed by the reciprocating pumps 1, 2 to the mixer 5. The solvent mixture is fed passed through a sample injector 8 and a column 6 and is detected 7. The constant-pressure valve 9, 10 are provided between the pumps 1, 2 and the mixer 5. The rotating speeds of the reciprocating pumps 1, 2 are so controlled as to periodically generate pulsation in synchronization with the reciprocating movements of plungers but to generate the specified pressure. Feedback is so controlled as to be applied only to the pump and not to be applied to the pump 2 on the other side by the action of the constant-pressure valve 9 when the liquid feed on, for example, the one pump 1 side is interrupted. The specified mixing ratio of the solvent is thus maintained. Since the constant-pressure valves are provided between the pumps and the mixer, the fluctuation of the mixing ratio is decreased and a smooth gradient curve is obtd.
