Abstract: The invention comprises a compact, reliable, and handy electrical connector for connecting two flat cables to a circuit board, by connecting the electrical circuits on the front side of the circuit board to one flat cable and the electrical circuits on the rear side of the circuit board to another flat cable.

Abstract: An electrical connector on which a first circuit board is mounted has a series of contact elements therein each with an end portion that projects from the connector, the end portion being soldered to a second circuit board. The connector has a slit parallel to each of the peripheral edges thereof. The slit is separated by bridge portions to form a plurality of openings. The locking means is provided with a protruded edge that engages with the surface of the first circuit board and hook portions each of which can be inserted into a corresponding opening and slid therein for preventing separation of the first circuit board and the connector.

Abstract: A method for the removal of mercury contained in a sulfur dioxide-containing gas which comprises contacting the sulfur dioxide-containing gas with an aqueous thiourea solution which optionally contains an acid at an acid concentration higher than one normal to selectively absorb mercury in a vapor state.
