Title: Image forming device
Inventor: HAYASHIDA HIDETOSHI
IPC: G06T7/40
Filed: 1994-03-31
Abstract: PURPOSE:To improve the picture quality of an image picture without deteriorating the picture quality of a font graphic picture by performing conversion into similar multi-valued data and printing the image picture with gradations only when the image picture is discriminated. CONSTITUTION:Input picture data stored in a storage means 6 are outputted sequentially and a picture discrimination means 7 discriminates a bit map picture to be outputted whether it is a font graphic image or an image picture as to pixels in. Only when the image picture is decided, a picture processing means 8 performs similar binary-tomulti-valued conversion processing and sends the result to a picture recording means 3, so that gradational print processing is performed. The picture discrimination is performed by comparing the number of successive black-and-white components with a specific threshold value. Thus, the font graphic picture is printed in binary mode and the image picture is printed in multi-valued mode, so that the picture quality of the image picture can be improved without lowering the picture quality of the font graphic picture.

Abstract: PURPOSE:To prevent damage of an opening and closing valve, by providing a pressure regulating means which limits pressure in the upstream side in the intake air recirculating direction of the opening and closing valve in an intake air recirculating passage to be not higher than a preset value not damaging the opening and closing valve. CONSTITUTION:At low load operation, an opening and closing valve 15 is closed, and an intake air recirculating valve 9 is opened and closed with a time delay for an intake valve 7. At a compression stroke of an engine E, intake air in a cylinder C is partly recirculated to an intake passage through an intake air recirculating port 3 and an intake air recirculating passage 14. If pressure in the upstream side in the recirculating direction of the valve 15 increases higher than preset pressure, output voltage of a pressure sensor 20 increases higher than output voltage of a preset voltage generator circuit 22. A control signal is output by a comparator circuit 21 and amplified by an amplifier circuit 23 then supplied to an actuator 24. This actuator 24 operates a valve 13 in the closing direction to regulate an intake air amount, as a result, pressure of recirculated intake air is decreased to prevent damage of the valve 15.
