Title: Method and system for inspection of electroconductive film using eddy current and process and system for production of optical fibres using method and system
Inventor: KOHMURA YUKIO
IPC: G01N27/72
Filed: 1991-05-28
Abstract: METHOD AND APPARATUS FOR INSPECTION OF ELECTROCONDUCTIVE FILM USING EDDY CURRENT AND PROCESS AND APPARATUS FOR PRODUCTION OF OPTICAL FIBERS USING METHOD AND APPARATUS              ABSTRACT OF THE DISCLOSURE      A method and system for accurately inspecting an electroconductive film using an eddy current and a process and apparatus for production of an optical fiber which measures on-line the electrical resistance, which shows the state of formation of the electroconductive hermetic coating  of the optical fiber by the electroconductive film inspection method and reflects back the measurement results to the hermetic coating forming conditions are disclosed. Optical fiber is made up of a core, cladding, amorphous carbon film or other electroconductive hermetic coating formed on the outer surface of the cladding, and a protective coating. The electrical resistance of the hermetic coating generates an eddy current at the coating, the eddy current generated is detected, and the phase angle of the complex impedance is detected to enable calculation. In particular, to accurately detect the phase angle, the high frequency current for generating the eddy current is changes by a low frequency of about 1/100th of the high frequency to change the average intensity and obtain at least two points of measurement defining the above phase angle. The electrical resistance of the hermetic coating is calculated from this phase angle. The electrical resistance shows the state of formation of the hermetic coating. The measurement value of the electrical resistance of the hermetic coating is used for setting the hermetic coating production conditions. The electroconductive film inspection method of the present invention may also be used for quality control etc. of thin films.

Patent CA-2050144-A1 (CA)
Inventor: FLONC NICHOLAS P
IPC: B29B15/08
Filed: 1991-08-28
Abstract: A method for forming stabilized preforms for complex composite articles is disclosed using a solid meltable uncatalyzed thermosetting resin as the stabi-lizing agent.  The resin is applied to each layer of the preform and heated to melt the resin and bond the layers together.  After cooling, the resin resolidifies but does not set and thereby holds the layers in the desired preform shape.  The layers can be first formed into a flat sheet as a raw material from which shaped preforms can be made by cutting the sheet into sections which are placed over a mandrel and reheating to thereby remelt the solid resin to allow the preform to conform to the shape of the mandrel.  Utilizing this process allows complex composite parts to be easily preformed and assembled prior to placement in a mold for resin injec-tion molding, without inhibiting part strength as the resin is compatible with the injection resin and is co-catalyzed by the catalyst contained in the injection resin.

Abstract: In a  sliding roof  for  automobiles,  comprising  a  non-slidable, front wind deflector, pivotal at its front edge in a roof opening, and a rear sliding lid, slidably guided in the roof opening, the roof opening is filled by the mutually adjoining surfaces of wind deflector and sliding lid when the roof is closed.  For creating a ventilation gap of high effectiveness between the rear edge of the wind deflector  and  the  front  edge  of  the  sliding  lid  in conjunction  with  an  aerodynamically  favourable  small pivoting out angle of the wind deflector, it is provided that the sliding lid, starting from its closed position, is pivotally journalled about a pivot axis provided in the vicinity of its rear edge, in the sense of lowering its front edge.  For the opening displacement, the sliding lid is also lowered at its rear edge, with the result that, with low overall depth of the roof construction, the lid is displaceable approximately in a parallel orientation to the roof surface beneath a rear roof surface.            A threaded cable drive assembly can be used to provide the actuating movements both of the wind deflector and of the sliding lid.
