A device to facilitate post-operative sternal closure by twisting the opposite end regions of the suture wire together comprises spaced guides in the form of limbs (1 and 2) with passageways (3 and 4) through which the proximal wire ends (12) and (13) may be fed and a cross-piece (7) transversely positioned with respect to said guides whereby, in use, the wire end regions may be bent across and supported by the cross-piece. The cross-piece includes a discontinuity (8) with a spacing adapted to be less than the thickness of wire. As the tension in the wire increases during the course of the twisting motion a point will be reached when the wire end regions forcefully deform the cross-piece (7) enabling the wires to pass through the discontinuity. Thus an indication is given when a maximum tension is reached.

An RF switching circuit according to the present invention includes: a plurality of input / output terminals for inputting and outputting an RF signal; and a switch for opening and closing an electrical connection between the input / output terminals. The switch is constituted by a multi-gate field effect transistor including a plurality of gates located between source and drain spaced from each other on a semiconductor layer. A bias voltage is applied to an inter-gate region of the semiconductor layer between the gates. The bias voltage is equal to or lower than 90% of a high-level voltage, which is a voltage for turning the multi-gate field effect transistor ON, in a state where the multi-gate field effect transistor is ON, and is equal to or higher than 80% of the high-level voltage and equal to or lower than the high-level voltage in a state where the multi-gate field effect transistor is OFF.

The present invention provides an ink-jet ink including a coloring material, water, and a water-retentive, water-soluble organic compound, wherein the water-soluble organic compound includes only a water-soluble organic compound showing a difference of 36% or less between the water retention ability at a temperature of 23° C. and a humidity of 45% and the water retention ability at a temperature of 30° C. and a humidity of 80%; and the content of the water-soluble organic compound is 15 mass % or more with respect to the total amount of the ink-jet ink.

A connector is to be attached to a coaxial cable. The connector includes a connector housing having a cylindrical shape to be coupled to the outer conductor. An insulator member has a central opening therein and is rotatably received within the connector housing to define a rotational joint therewith. A center contact has a shaft portion securely received within the central opening of the insulator member and an open end portion extending rearwardly from the shaft portion to securely receive the inner conductor therein.
