Abstract: A connector device comprises a connector and a mating connector connectable with each other. The mating connector comprises a mating primary terminal and a mating secondary terminal. The connector comprises a primary terminal, a secondary terminal, an operation member and a push-back mechanism. The operation member changes its state from an initial state to a second state via a second state. When the state of the operation member is changed to the first state, the primary terminal is connected to the mating primary terminal. When the state of the operation member is changed to the second state, the secondary terminal is connected to the mating secondary terminal. When the state of the operation member is changed to the first state, the push-back mechanism applies a push-back force to the operation member to change the state of the operation member back toward the initial state.

Abstract: The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.
