摘要:
A deflection yoke for a cathode ray tube improves assembly and productivity and enables effective control of magnetic field corrections during device processing. The deflection yoke includes a horizontal deflection coil located next to the outer circumference of a funnel to generate a horizontal magnetic field, and a vertical deflection coil installed at the outer circumference of the funnel to generate a vertical deflection magnetic field. The vertical deflection coil is insulated from the horizontal deflection coil. A ferrite core is located close to the vertical deflection coil to reduce the loss in the magnetic force generated from the horizontal and vertical deflection coils, and to enhance their magnetic efficiency. A correction unit is spaced apart from the horizontal deflection coil by a predetermined distance to correct a geometric distortion of the vertical and the horizontal deflection magnetic fields that is generated due to the vertical and horizontal deflection coils.

Techniques for controlling nucleic acid structures include determining, for each junction type, values for parameters indicating ground-state geometry and both translational and rotational stiffness coefficients. Topological design data indicates a number of bases in each helix connected to corresponding junctions. Initial positions of each base are determined by connecting helices to junctions using the ground-state geometry and arbitrary coordinates not confined to lattice coordinates. Misalignment vectors each indicate a difference in coordinates and orientations between initial positions of a pair of bases that are not adjacent in the initial positions but are adjacent or coincident in the design data. Forces and moments at the junctions to reduce misalignment magnitudes are determined based on the translational and rotational stiffness coefficients at each junction. Position and orientation in 3D coordinates of each base are determined by reducing or eliminating the misalignment magnitudes and balancing forces and moments across the nanostructure.

Techniques for controlling properties of nucleic acid nanostructures include receiving data that indicates a sequence of nucleotides on at least a first strand of a nucleic acid. Values are determined for at least one physical property for each portion of the at least first strand. Based at least in part on a numerical model and the physical properties for each portion, a value is determined of at least one derived property of a nanostructure that comprises the at least first strand of nucleic acid. In some embodiments, information gained from the numerical model is used iteratively in order to optimize or improve one or more of the properties of the target DNA origami structure.

摘要:
A cathode ray tube for reducing a deflection power without any BSN problem is disclosed. The cathode ray tube has a panel, a funnel having a deflection yoke on an outer periphery thereof, and a neck connected to the cone of the funnel. A phosphor screen is arranged on an inner surface of the panel. The funnel includes a body connected to the panel, and a cone connected to the body. The cone has a deflection power reducing shape which is formed to have a range of length 0.25×L from an end of the cone at the neck where L is an entire length of the cone measured along an axis of symmetry of the cathode ray tube.
