Filed: 1983-07-05
Abstract: PURPOSE:To obtain an image having a high quality by changing a carrying path length between a feeding means and an inserting and holding means, to the direction for absorbing a loop generated between both means, after the tip of a transfer material has been inserted and held, and eliminating an uneven transfer and a color shift caused by the loop. CONSTITUTION:A transfer material supplied by a resist roller 6, and inserted and held by a gripper 5 through a guide plate 7 is carried to a transfer position 4 of a transfer drum 2. A short diameter surface of an eccentric roller 14 is always on the path side of the transfer material, but after the transfer material has been inserted and held, before the gripper 5 reaches a connecting position to an elastic body 12 of a paper holder 10, the roller 14 makes a half rotation, and a path length of the transfer material is lengthened, therefore, a loop which is apt to be generated in the transfer material is absorbed. Accordingly, the loop of the transfer material, which is generated after the transfer has been inserted and held by the gripper is absorbed, a good transfer is executed, and a transfer image having a high quality is obtained.

Filed: 1986-05-27
Abstract: PURPOSE:To make sure of fuel transfer, by installing each pressure regulating valve in a main tank and a subtank, and making the pressure differential required for the fuel transfer so as to be secured between both these tanks all the time, in case of the above-captioned system for an automobile. CONSTITUTION:When internal pressure inside a main tank 10 goes up as receiving the effect of outside temperature or volatility of service fuel, a pressure valve 24 is closed, and another pressure valve 22 is opened to the atmosphere whereby internal pressure in an air chamber 38 of the tank 10 is lowered down to the specified pressure. On the other hand, in the subtank 26, a pressure valve 36 is closed and another pressure valve 34 is also closed because positive pressure inside this subtank 26 is less than the setting valve. And, when an internal pressure differential between the main tank 10 and the subtank 26 is still more insreased, fuel shifts from the subtank 26 to the main tank 10 by dint of this internal pressure differential. With this constitution, fuel transference can be done surely without being affected by outside temperature and volatility of the fuel.
