A spiral contactor for establishing an electric connection with a semiconductor device or an electronic part including a solder ball includes a spiral probe having a spiral shape, as viewed from the top. The spiral probe is embedded in an insulating substrate in a manner that permits resilient deformation thereof in accordance with a shape of the solder ball. An edge of the spiral probe is pressed to engage the solder ball, and slides along a periphery of the solder ball, thereby cutting an oxide membrane thereon. The spiral contactor may be manufactured by combination of the photolithography technique and the plating process, and used for a semiconductor inspecting apparatus and an electronic part.

An ink fountain apparatus in an ink supply system for use with a printing press. The apparatus comprises an ink reservoir provided with an ink fountain, an ink steering/collecting section formed in a zone of the ink reservoir and in which a screw adapted to stir, transfer and collect ink is rotatively mounted therein, an ink delivery section for delivering ink into the ink reservoir, and a pump installed between the ink steering/collecting section and the ink delivery section. A suction port of the pump is directly connected to an ink collecting zone of the ink steering/collecting section where ink is collected through the action of the screw.

Ink fountain apparatus

The present invention relates to an ink supplying device adapted for a rotary press used for printing news papers. More particularly, the present invention relates to an ink supplying device comprising an inking cylinder, an ink feeding means for feeding ink to the inking cylinder, and an ink temperature control means for controlling the temperature of the ink to be fed to the inking cylinder within the optimum range. The temperature control means comprises a medium circulating unit including a medium chamber, a medium temperature detecting unit, a heater and a cooler; a heat exchanger; a pipe system for circulating between the medium circulating unit and the heat exchanger; and an ink temperature detecting unit. The heat exchanger is preferably selected from plate type heat exchangers. This system allows that the ink temperature is quickly adjusted to the optimum range for printing work and further always maintained within the optimum range during its printing work.
