摘要： PROBLEM TO BE SOLVED: To obtain a more uniformed magnetic field intensity distribution compared with a conventional manner in a convergence yoke which generates a bipolar magnetic field to deflect an electron beam in a horizontal or vertical direction. SOLUTION: The convergence yoke is constituted by winding horizontal coils 2 and vertical coils 3 around a ring core 1. The winding wire density distributions of the coils are defined with winding wire angles θ from a horizontal coil reference axis 20 and a vertical coil reference axis 30 as a variable number and are each proportional to cos 2 θ in the horizontal and vertical coil 2 and 3.

摘要： PROBLEM TO BE SOLVED: To provide a holder which can fix object to the specified position simply through a strong magnetical attraction and can simply take out the object through disengagement of the magnetic attraction force. SOLUTION: A holder includes a magnetic force generating yoke part 22 in plane form of such an arrangement that magnets 28a-28e and magnetic bodies 32a-32f are adjoiningly installed alternately. A slide plate 34 is equipped with a first 40 and a second sliding yoke 48 and installed on the yoke part 22 slidably. The first sliding yoke 40 is formed so that magnetic bodies 44a-44f and non-magnetic bodies 46a-46e are adjoiningly installed alternately, while the second sliding yoke 48 is formed from magnetic body in plane form. Over the yoke part 22, a fixing plate 54 is installed with the slide plate 34 interposed, and is furnished with a stationary yoke 60 in a position mating with the yoke part 22. The slide plate 34 is slid so that the first 40 and second sliding yokes 48 are selectively positioned on the yoke part 22 opposingly.

摘要： PURPOSE:To lessen the hysteresis loss of a magnet for magnetic bearing by a method wherein the magnet for magnetic bearing is constituted of a multiple annular magnet formed by combining a plurality of annular magnets into a concentric circle form, the outer box of the multiple annular magnet and upper covers, which are formed by forming integrally more than two concentric circle-shaped materials having different magnetic permeabilities by soldering and fixing and are used in combination as magnetic diffusion members. CONSTITUTION:Concentric grooves 7 are bored in a high-magnetic permeability material 4 of a constant thickness, annular members 5 consisting of a non-magnetic material are inserted in these grooves 7 and after being bonded to the grooves by copper soldering, the members 5 are shaped into an upper cover form. Here, the soldered thin plate parts of the members 5 are finished thin and precisely while a grinding resistance is adjusted by using together a cutting tool, discharge processing and the like for shaping of the soldering thin plate parts. Then, the upper covers are made to make a soft landing on a separately formed insertion fixing finished magnetic circuit with a magnetic case using an insertion jig or the like, the upper covers are mounted on the magnetic case and are screwed by a terminal 3c. Thereby, a magnet for magnetic bearing, which is small in hysteresis loss and is mounted with a magnetic flux diffusion member which can withstand high-speed rotation, can be manufactured.

摘要： PURPOSE: To keep freshness over a long time and hence ensure healthy foods by constructing a present apparatus with magnetic energy generation means provided at a portion adjacent to foods drink water stored in a refrigerator or provided between an external box and an internal box of a refrigeration chamber. CONSTITUTION: Magnetic energy generation means employs a permanent magnet or an electric magnet optionally or in combination. When there is employed a permanent magnet as the magnetic energy generation means, a permanent magnet 4 is molded in an outer case 3. The reason the permanent magnet 4 is molded in the outer case 3 is that the permanent magnet 4 has very large oxidization so that it should be previously prevented. When the permanent magnet 4 is molded in the outer case 31, the divided permanent magnets are arranged such that they are disposed longitudinally and laterally with polarities being arranged alternately. When the permanent magnets are located at a lower portion of an ice container, production efficiency of hexagonal water is made maximum. When they are arranged around foods, a line of magnetic force is applied into the foods to suppress evaporation of the water.
