Abstract: PROBLEM TO BE SOLVED: To prevent falling down of a road mark device by connecting one side fringe of two substrates with lower fringes of two display plates connected in such a manner that an upper fringe can be folded down outward, respectively, in such a manner that they can be folded down and connecting the other side fringes of the substrates in such a manner that they can be folded down inward. SOLUTION: Among display plates 10, 11 which are made of flat sheet and of which plan shape is trapezoid, for example, the display plate 10 is directed toward a car which passes, and substrates 12, 13 are brought into contact with a road surface to arrange a road mark device on a road. When the display plate 10 receives wind pressure due to the car which passes and is pushed up and the substrate 12 attempts to bend centered on a face hinge 19 an end fringe of the substrate 12 hits against an end fringe of the substrate 13 to prevent its bending and falling down of the road mark device. Moreover, after the road mark device is used, the substrates 12, 13 are pushed in inward and the display plates 10, 11 are pushed from both sides.  The display plates 10, 11 are folded down in the shape of reverse V character with a face hinge 16 as vertex and the substrates 12, 13 are folded down in the shape of reverse V character with the face hinge 19 as the center.

Title: Dynamic focus circuit
Inventor: TANAKA TAKAMASA
IPC: H04N3/26
Filed: 1992-06-05
Abstract: PURPOSE:To decrease the focus tracking error brought about by high-voltage fluctuation by applying focus voltage which follows up the high-voltage fluctuation by superimposing a correction signal. CONSTITUTION:If a high voltage changes by the rapid fluctuation of the high- voltage load in an anode electrode 4 of a cathode-ray tube 3, the ripple component in proportion with the high-voltage fluctuation amount is detected by the bleeder resistance of FBT1, which is amplified by a correction circuit 6 and supplied to a focus voltage supply adjustment circuit through a capacitor C2, then superimposed to the focus voltage and applied to a focus electrode 5. Thus, the phase delay of the focus voltage tracking is compensated according to the high-voltage fluctuation and the tracking error can be reduced.

Title: System for localization of instrument in selected tracking capacity
Inventor: DUMOULIN CHARLES L
IPC: G01R33/36
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a tracking system capable of more accurately tracking an invasive device within the body of a subject in the presence of an eddy current inducing structure. SOLUTION: A tracking system applies to a transmitting coil 130 a current corrected to compensate the influence of an eddy current. The current is a linear combination of the current needed to generate the desired magnetic field in an area of concern and an error item represented by a mathematical model of a series of exponential functions experimentally determined during system calibration and having a predetermined amplitude and time constant. The error item of the current cancels out a magnetic field generated by the eddy current within a tracking region to approximate an actual electromagnetic field to the desired ideal electromagnetic field.  By decreasing the eddy current in an eddy current inducing structure, the fidelity of the electromagnetic field is further enhanced, which is achieved by composing a shielding coil placed between the transmitting coil and the eddy current inducing structure.

Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To eliminate distortions occurring unequally in upper and lower parts of a picture frame due to a deflection yoke even after the position of the deflection yoke has been set up.

Title: Silver alloy filler metal for brazing
Inventor: KASHIWAGI KOZO
IPC: C22C5/06
Filed: 1987-06-12
Abstract: PURPOSE:To reduce roughness and ruggedness after brazing and to inhibit tarnish and corrosion by residual cleaning soln., by specifying the compsn. of an Ag alloy filler metal for brazing. CONSTITUTION:This Ag alloy filler metal for brazing has a compsn. consisting of, by weight, 20-55% Cu, 3-15% In, 0.001-1.5% P, 0.001-1.0% Si and the balance Ag. The reason that P and Si are contained in the Ag alloy filler metal is that P and Si reduce the surface tension of the filler metal during brazing, suppress the surface roughening of the filler metal and inhibit the occurrence of ruggedness. The P and Si contents are limited because <0.001% P or Si can not inhibit the surface roughening of the filler metal and the occurrence of ruggedness and >1.5% P or >1.0% Si enhances the flowability of the filler metal. By the enhanced flowability, the filler metal flows to a part of a base metal not to be brazed and deteriorates the corrosion resistance and fine appearance. In addition, >1.5% P or >1.0% Si forms a P-Si compd. on the brazing interface and imparts unfavorable influence on brazing strength.
