Abstract: A scanning optical head for a catheter is locally controlled by a motor at an insertion end of the catheter uses a hollow motor through which a longitudinal optical path of the catheter passes. This permits the motor to be positioned between a control base of the catheter and avoids rotating the whole fiber, and therefore makes the beam scanning stable and accurate. In addition, because there is no coupling component, it also eliminates the light reflection between additional surfaces as well as varying fiber birefringence, which becomes a cause of noise when imaging the deep structure.

Abstract: In a liquid crystal display panel, a liquid crystal layer is sandwiched between a TFT substrate and a color filter substrate. An ITO film is formed on a front surface of the color filter substrate. By supplying an electric current to the ITO film at the time of staring an operation of the liquid crystal display panel, a temperature of the liquid crystal layer is elevated to a level which allows the liquid crystal layer to perform a normal operation within a short time. By forming a plating electrode on two sides of the color filter substrate, it is possible to uniformly supply an electric current to the ITO film thus enabling uniform heating of the color filter substrate.

The release mechanism may include a cam mounted bail that rotates a U-shaped flange through a two stage travel path to urge the bail forward in a slide path on the transceiver module.
