Title: Image processing type traffic flow measuring instrument
Inventor: NISHIYAMA KAZUTO
IPC: G01V8/10
Filed: 1990-03-15
Abstract: PURPOSE:To eliminate the influence caused by a shadow and to improve the discrimination of the kind of a car and the car number measuring accuracy by constituting the measuring instrument so that when a distance on a road surface of feature points of a car head and a side part of a vehicle is not varied from two-dimensional screen data subjected to image pickup from the upper part at a prescribed angle, it is detected as a part of the shadow. CONSTITUTION:An image pickup image is digitized from the upper part by a fixed camera 1, subjected to ternary conversion processing and a car head candidate is detected. When extracted two-dimensional data satisfies a reference value, a car head detecting part 24 decides it to be a vehicle, and a shadow discriminating part 25 tracks a timewise moving distance of the vehicle of every measuring period. The discriminating part 25 checks a variation of a distance between feature points of a car head part and a car side and in the case the distances on the road surface are equal irrespective of the lapse of time, its feature point is detected as a part of a vehicle shadow. A vehicle measuring part 2 sets this vehicle shadow as a noise, eliminates the part of the shadow from data of an image storage part 22 and recognizes only a car body. These traffic measured data are sent out to a central equipment from an output part 27. Accordingly, from an image measuring part 2, exact vehicle discriminated data and passing car number measured data which are not influenced by the shadow are obtained.

Title: Take-up device for optical fiber cable
Inventor: TOMITA YUICHI
IPC: B65H54/02
Filed: 1987-03-19
Abstract: PURPOSE:To eliminate the torsion of a cable without using a connector and rotary drum by constitutionally protrude the cable upward from below a hollow shaft through respective sets of large and small diameter sheaves and taking out the cable downward from the rear bottom wound around an inner tube. CONSTITUTION:In the case of taking up a cable 20 for example, the counterclockwise rotation of an arm 4 rotates clockwise a large diameter feed sheaves 5, 8 about their own axes while revolving counterclockwise them. A cable 20 is fed from below the central portion of device through the interior of a hollow rotary shaft 19 and a guide section 21 along a feed sheaves 5, 8 to be wound around the outside of an inner tube 2. Gaps between the feed sheaves and between the feed sheave 8 and a small diameter sleeve in close contact therewith is slightly smaller than the diameter of cable 20 and the cable 20 is fed by a frictional force produced there and a frictional 1 force produced in portions of the sheaves 5, 8 along the cable to be wound around the outside of the inner tube 2. This is reversed in the case of feeding out the cable. Thus, torsion can reduced since the cable is twisted once per one revolution of large diameter feed sheaves 5, 8.
