An endoscope is connected optically removably to a TV camera through an adapter. A plurality of fixing pins is arranged on both sides of an insertion axis of an insertion part of the endoscope. A fixing unit to fix the endoscope removably is provided at the front end of an arm unit of an endoscope holder which supports the endoscope movably. The fixing unit has a claw and a movable claw, and grips the fixing pins of the endoscope releasably between the claw and the movable claw.
摘要:
A magnetic polishing method capable of easily and satisfactorily polishing the inner peripheral end face of a circular hole (1) at the center part of a disk substrate (2) even if the diameter of the circular hole is reduced. By this method, a large quantity of disk substrates with stable quality can be supplied, thermal asperity trouble and head crush can be prevented from occurring on a magnetic disk, and the density of the information recording surface of the magnetic disk can be increased. In the method for polishing the inner peripheral end face of the circular hole (1) at the center part of the disk substrate (2), a magnetic field is formed on the inner peripheral side of the circular hole (1), abrasive materials (4) including magnetic particles and abrasive grains are held by the magnetic field in the circular hole, and the magnetic field is moved to the inner peripheral end face of the circular hole (1) to move the abrasive materials (4) to the inner peripheral end face of the circular hole (1) for polishing the inner peripheral end face of the circular hole (1).
摘要:
A surgical microscope apparatus incorporating a frame portion placed on a floor, a microscope body for stereoscopically observing a portion to be operated, an arm portion supported by the frame portion and arranged to suspend the microscope body, and an endoscope for observing a blind spot for a stereoscopic observation field of view. The frame portion has a light source unit for generating light for illuminating a portion observed with the endoscope and a camera control unit for processing an observed image of an observed portion obtained by the endoscope. A light guide fiber extending from the light source unit to the microscope body and capable of supplying light to the endoscope, and a camera cable for transmitting the image observed with the endoscope to the camera control unit extend in the arm portion. The microscope body is provided with an end of the light guide fiber for connecting the endoscope and a camera head connected to the camera cable.
