Title: Method for manufacturing holey fiber
Inventor: NAKAZAWA MASATAKA
IPC: C03B37/027
Filed: 2002-04-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a holey fiber with increased strength and low OH absorption loss.  <P>SOLUTION: Since chlorine is present in the gas filled into pores 10h formed in a quartz preform 10 for an optical fiber, OH groups diffusing in a core during drawing the quartz preform 10 chemically react with the chlorine and decreases. Or, since gas containing chlorine fills the pores 10h instead of air, growth of fine cracks in the optical fiber due to water can be suppressed. This results in a high-strength holey fiber with low OH absorption loss.  <P>COPYRIGHT: (C)2004,JPO

Title: Endoscope
Inventor: NAKAYAMA REI
IPC: A61B1/00
Filed: 2002-04-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide an endoscope which is internally packaged with two channel tubes, makes the diameter reduction at the distal end of the endoscope possible and can provide a light bending capacity by decreasing the moving distances between the two channel tubes in a bending operation.  <P>SOLUTION: The diameter reduction at the distal end of the endoscope is made possible by arraying channel openings 7a and 7b communicatively connected with the respective channel tubes 14 and 50 in a vertical direction which is the bending direction of a bending section 2 on the distal end face 1a as shown in figure 2 and disposing a lens cover 9 for observation on the right side thereof. The channel tubes 14 and 50 are inserted to be screwed clockwise from the distal end to the bending section 2 and is arranged to line up in an approximately lateral direction within the bending section 2. At this time, the force tending to return the channel tubes 14 and 50 to the counterclockwise direction acts thereon and therefore this force is obstructed by a wire bracket 39 to maintain the posture that the channel tubes 14 and 50 are arranged in the approximate lateral direction. Consequently, the moving distances between the channel tubes 14 and 50 within the bending section 2 are decreased even when the bending section 2 is operated to be bent.  <P>COPYRIGHT: (C)2004,JPO
