IPC: G01N29/00
Filed: 1988-10-11
Abstract: PURPOSE:To measure the thicknesses of all films of ink and to improve printing quantity by irradiating a liquid film stuck on a body with laser light, and generating an ultrasonic wave in the body and detecting it. CONSTITUTION:The oily ink film A sticking on the outer periphery of an ink coating roller 8 is irradiated with the laser light 21 for excitation which is generated by a laser 20 for excitation. At this time, the ink film A vaporizes instantaneously and the ultrasonic wave 23 which is proportional to the thickness of the ink film A is generated by the roller 8. This wave reaches and end surface 24 of the roller 8, which is displaced finely. This fine displacement is detected with laser light 26 for measurement from a laser 25 for measurement. Then the thickness of the ink film A is measured from the result. The displacement of the end surface 24 need not be detected except for black ink which reflects a little laser light 21, and the thicknesses of films of ink including the black ink are measured by this detection.

Title: Pipe assembly cable for feeding optical fiber
Inventor: KOBAYASHI ICHIRO
IPC: G02B6/46
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a pipe assembly cable for feeding optical fibers which does not crush a pipe at the time of passing snatch blocks during installation. SOLUTION: A required number of pieces of pipes 2 for feeding optical fibers are stranded to form a pipe assemblage 5. This pipe assemblage 5 is wound around the outer periphery of a supplying wire 3 to form the pipe assembly cable for feeding the optical fibers. Since the pipe assemblage 5 is formed by bundling many pieces of the pipes 4, the assemblage has a better cushion property than in the case of one piece and since the dispersion and relaxation of pressing force are made possible by the relief arising from the movement (collapse of the array) of the pipes 4, the collapse of the pipes 4 does not arise any more.
