Abstract: The present invention relates to a flexible printed circuits, and more specifically, to a impedance controlled flexible printed circuits with differential mode transmission lines. Structural constrains such as small round hole is suitable for micro coaxial cables, but it normally is not suitable for the flexible printed circuits. This invention is to convert flexible printed circuits from a planar structure to multi-planar structure, so it can fit in other than the flat rectangular such as a small round hole or small square hole. Moreover, this structure is suitable for torsion torque. The pairs of the differential mode had better keep in the same layer to have the virtual ground for controlling impedance. It can be implemented with this invention in the flexible printed circuits. But it does not work for micro coaxial cables.

The second oxide layer is anisotropically etched back to leave oxide spacers within the partial contact opening wherein the partial contact opening not covered by the oxide spacers has a second width smaller than the first width. A contact opening is etched through the portion of the partial contact opening in the first oxide layer not covered by the oxide spacers to the semiconductor substrate whereby the photoresist mask protects the first oxide layer from damage during etching and wherein the contact opening has the second width. Thereafter, the photoresist mask is removed. A metal layer is deposited within the contact opening to complete the contact in the fabrication of an integrated circuit device.

Granted: 2002-11-01
Abstract: Herein disclosed is an ultrasonic probe comprising a housing, a driven shaft rotatably supported by the housing, a transducer supported by the driven shaft to be swingable on one side of the driven shaft and operative to transduce an electric signal to and from an ultrasound, a drive shaft rotatably supported by the housing spaced apart from and in parallel relationship with the driven shaft in the predetermined direction; a drive motor supported on the housing and drivably connected to the drive shaft; and a drive belt passed on the driven shaft and the drive shaft to transmit the rotation from the drive motor to the transducer. The transducer has the ultrasound emitted therefrom and reflected thereto through the housing in a predetermined direction. The ultrasonic probe thus constructed makes it possible to reduce the rotation radius of the transducer independently of the size of the electric motor by spacing the rotation axes of the drive motor and the transducer in order to provide an ultrasonic probe smaller in size. The rotation of the drive motor transferred into the rotational motion of the transducer without causing a backlash prevents the accuracy of the ultrasonic probe from deteriorating.
