摘要： PURPOSE:To promote working efficiency by storing a rear driving coil and a front driving coil in a spacer, and arranging coil units loading a levitation coil on an overlapping section of both coils on concrete panels in series. CONSTITUTION:A rear driving coil 14A is inserted into a rear coil storing groove 22 of a coil spacer 20 and, at the same time, a front driving coil 14B is inserted into front coil storing grooves 24R and 24L so that a half thereof is overlapped with the coil 14A. After that, a levitation coil 16 is loaded to the front section of an overlapping section of the coils 14A and 14B to form a main coil 52. Then, a half of the coil 14B overhanged from the unit 52 is continuously mounted to concrete panels 1 2 on side walls of a track while loading a half of the coil 14B in the storing groove 24L of the preceding unit 52. An end coil unit 54 is mounted to the panels 12. In addition, a coil 16 is mounted between the coils 16 arranged off and on by being attached to the units 52 and 54 arranged in series.

摘要： PROBLEM TO BE SOLVED: To reduce eddy-current loss occurring in a conductor by using a conductor of plural circular cross-section insulating conductors, for larger space factor and simpler coil configuration. SOLUTION: Firstly, a conductor 17 of circular cross-section is covered with an insulating coat 18 to manufacture the conductor 17 where each conductor is insulated. Plural conductors are collected together at straight angle to form a conductor 10. Further, the entire conductor 10 is compressed to reduce a space 19 of the conductor 17. The insulating coating 18 comprises an enamel coat. Thus, the number of conductors is easily increased without reducing a space factor, while stage-transition part is simply configured, so that a ground- coil, with no circulating-current and less eddy-current loss, may be configured with ease.

摘要： PURPOSE:To prevent lubricant from leaking, a machine from being deteriorated due to the mixture of foreign matters, and a roller bearing from being damaged, by arranging ring-shaped elastic rubber units almost to come in contact with a rotary shaft, between the inner diameter side of lubricant filler chambers confronting the side face of the roller bearing and the rotary shaft. CONSTITUTION:Oil seals 100 are fixed on the inner diameter side of lubricant filler chambers 60 and 70 arranged on bearing covers 40 and 50 placed on the both sides of a roller bearing covers 40 and 50 placed on the both sides of a roller bearing 2. Generally, metal rings 100E are arranged on the outer diameter side. Open air is absorbed into a machine through an air chamber 8 via an air passage 10 through an air chamber 9. The main units 100D of the oil seals 100 are generally made of elastic rubber, and the material is determined subject to the adequate use. On the inner diameter side, namely, on the surface confronting a rotary shaft 1, lips 100A and 100B are arranged on the both sides, and the sections are arranged to come in contact with the rotary shaft 1. Accordingly, lubricant and base oil can be prevented from being leaked by the one side lip, and foreign matters included in open air can be prevented from being infiltrated by the counter side lip.
