Title: Method and equipment to detect different kind of substance in fiber test sample
Inventor: KURUTO ETSUPURI
IPC: G01V8/12
Filed: 1994-07-28
Abstract: PURPOSE: To detect a foreign substance by projecting an image of a sample onto the light (dark) background for the foreign substance to be detected, darker (lighter) than the test sample, without specially performing the matching of the background to the sample. CONSTITUTION: A string F as a test sample, is illuminated by the front and rear illuminating means 5, 6, and the image of the string F is projected on a line sensor 3 by an objective 2. A transmitted light illuminating means 7 uniformly illuminates the frosted glass 4 forming the background to the image of the string F, and the string F is scanned in front of the optical background. Thereby the foreign substance darker than the string F can be sensed by a sensor 3. To detect the foreign substance ligher than the string F, the illumination 7 is switched off. Only the signal component generated from a core part of the string F can be evaluated by the sensor 3. Thereby the influence of the change of the diameter of the string F, upon the sensor signal, can be removed.  A signal processing stage generates a foreign substance signal, when the signal from the sensor 3 is more (lower) than the threshold value for the light (dark) foreign substance.

When a vehicle speed reaches a high speed region, the turbine shaft 6 and the driven shaft 12 are directly connected together by a high-speed clutch 44 and a high-speed gear train 41. During reverse running, the driving force is transmitted through gears 21, 25 and 26 with a fixed gear ratio, but torque transmission by a V-belt type continuously variable mechanism 10 is not carried out. Thus, as the power transmission by the V-belt 19 is stopped during maximum speed running and reverse running, a life of the belt may be greatly improved.

Abstract: PURPOSE:To obtain large reproduction output by disposing a Co evaporation source and Cr evaporation source in the direction approximately orthogonal with the traveling direction of a nonmagnetic base at the time of forming a perpendicularly magnetized Co-Cr film. CONSTITUTION:The Co evaporation source 6 and the Cr evaporation source 7 are disposed in the direction approximately orthogonal with the traveling direction of the nonmagnetic base 1 at the time of forming the perpendicularly magnetized Co-Cr film on the long-sized nonmagnetic base 1 by a two-sources vapor deposition method while running the nonmagnetic base 1. The perpendicularly magnetized Co-Cr film to be formed is made of the compsn. which is consistent in the thickness direction of the magnetized film. The magnetic film having no change in the compsn. is thus formed. Since there is no change in the compsn. over the entire part of the magnetic film, the saturation magnetization Ms and coercive force Hc in the perpendicular direction can be uniformized in the thickness direction of the perpendicularly magnetized film. The large reproduction output is thereby obtd. as the entire part of the perpendicular magnetic film contributes to effectively to the reproduction output.
