Abstract: An apparatus and method is disclosed for preventing accidental overradiation of a patient in surgical procedures involving both fluoroscopy and endoscopy. Video outputs from a fluoroscope and an endoscope are connected to a switching device. The physician uses the switching device to select from between the endoscope video output and the fluoroscope video output for viewing on a video monitor. When the endoscope video output is selected for viewing, the switching device automatically deactivates the X-ray generator of the fluoroscope. When the switching device is actuated to select the fluoroscope video signal for viewing on the monitor, the switching device automatically reactivates the X-ray generator. In this manner, overradiation of the patient during periods when the fluoroscope is not being used is avoided. In one aspect, the switching device comprises means operable to convert at least one of the endoscope video signal or the fluoroscope video signal from one video format to another video format compatible with the video monitor.

Abstract: ABSTRACT     A label comprising a polyethylene film in which the degree of crosslinking inwardly decreases across the thickness of the film and on one side of which printing is performed, and an adhesive layer further formed thereon.  The label is good in clarity, is possible to perform back surface printing, can provide an integral feeling and a high-class feeling as if curved-surface printing is performed on a cylindrical container itself, is sufficient in rigidity and strength and therefore is possible to be thinly formed, is resistant to water wetting and contamination, is unnecessary to be stripped in recovering and recycling a polyethylene bottle when the label is stuck thereon, can be stuck on the bottle concurrently with blow molding of the bottle printed, and is therefore suitable for use as a label for in-molding.   Degassing is carried out by forming an uneven surface on the adhesive surface, whereby the blister phenomenon can be avoided when the label is stuck on the surface of a bottle concurrently with blow molding of the bottle.  When a primer layer intervenes between printing ink and the adhesive layer, the label excellent in the adhesive strength between the printing ink and the adhesive layer can be obtained.
