摘要:
Using an endoscope system, a surgeon A holds an endoscope with a TV camera (hereinafter, an endoscope) and a therapeutic appliance such as forceps and carries out a surgical procedure while viewing a first monitor. A surgeon B holds a therapeutic appliance such as forceps and carries out the surgical procedure while viewing a second monitor. A video signal sent from the TV camera of the endoscope is fed to and processed by an image processing apparatus, and displayed on each of the first and second monitors. The image processing apparatus transfers the video signal sent from the endoscope to each of an image inverting circuit and a selector switch. The image inverting circuit inverts an image (laterally (to produce a mirror image), vertically, or vertically and laterally (180°)), and supplies a processed video signal to the selector switch. The selector switch selects a video signal to be supplied to each of the first and second monitors, which are display units, in response to a control signal sent from a selector. The contents of processing to be performed by the image inverting circuit and the video signal to be selected by the selector are designated using setting switches on an operation panel.
摘要:
In a data receiver, pulse edges are sequentially detected from the pulse string. If a pulse which has a width equal to two cycles of the reference clock signals is detected, bit data ‘1’ is restored. If two consecutive pulses each of which has a width equal to one cycle are detected, bit data ‘0’ is restored. If a pulse width between two consecutive pulse edges is not equal to one cycle or two cycles, it is presumed that a pulse edge of an erroneous pulse is detected. If the pulse width between the pulse edge, which is presumed to correspond to the erroneous pulse, and the next pulse edge is equal to or shorter than a predetermined threshold Th, the pulse edge and the next pulse edge is invalidated.

摘要:
Observation assisting forceps wherein a shaft member is retractably inserted through a hollow sheath, a plurality of linear members given a characteristic of expanding on the tip sides are provided at the front end of this shaft member and spherical parts are provided at the tips of the respective linear members so that the linear members may be projected on the tip sides out of the sheath tip to move aside any organ or the like obstructing the observation with an endoscope.
