摘要： PROBLEM TO BE SOLVED: To use a specific set of diode rectifiers with the same specifications and to reduce harmonics effectively by setting the number of slots per the single pole single phase at the secondary side of a coil winding type induction electric rotating machine to an even number, leading coil winding at positions that are in the same pole and in phase and deviate by specific angles each other in terms of an electrical angle, and connecting a rectifier to each coil winding. SOLUTION: A primary side (stator) 3 of a coil winding type induction electric rotating machine 1 that is mechanically connected to a load or a motor 2 is connected to a system 9, secondary coil winding 5 and 6 with a phase difference of 30 deg. in terms of an electrical angle is led from a secondary side (rotor) 4 by such feeding means as a slip ring, and a variable resistor 10 is connected via diode rectifiers 7 and 8 that are connected in parallel. The number of slots of one pole one phase at a secondary side has been set to four. However, when three-phase balanced coil winding is to be formed at the secondary side, two sets of three-phase three-wire type balanced coil winding 2 with the same voltage and a phase difference of 30 deg. in terms of an electrical angle can be obtained if the number of one pole one phase slots is even since the electrical angle of one pole one phase is 60 deg. when forming three-phase balanced coil winding at the secondary side.

摘要： PROBLEM TO BE SOLVED: To provide a lining method of an inner face of existing piping capable of preventing deterioration of workability caused by increased tube thickness for enhancing pressure resistance, and also preventing deterioration of pressure resistance caused by decreased tube thickness, which are common problems of conventional lining methods for repairing existing piping from inner faces by using lining tubes as coating materials inside pipes.
SOLUTION: A cylindrical net 2 and an uncured lining material 3 are used as a lining material of the inner face of the existing piping 1. The cylindrical net 2 is inserted from an opening of one end of the piping 1, and the uncured lining material 3 is poured inside the opening of one end of the cylindrical net 2 inserted in the piping 1. The lining tube 42 is inserted from the opening of one end of the cylindrical net 2 so that the uncured lining material 3 is pressed forward so as to fill into meshes of the cylindrical net 2 on the entire circumferential area. The pressure inside the lining tube 42 is maintained until the uncured lining material 3 is hardened. After the lining material 3 is hardened, the lining tube 42 is drawn out from the piping 1 so that a cured lining layer B with the cylindrical net is formed on an inner circumferential face of the piping 1.

摘要翻译：要解决的问题：为了提供现有管道的内表面的衬里方法，其能够防止由于增加的管厚增加而导致的加工性的劣化，以提高耐压性，并且还防止由管厚度减小引起的耐压性的劣化，是通过使用衬管作为管道内的涂层材料来修复内表面的现有管道的常规衬里方法的常见问题。
解决方案：使用圆柱形网2和未固化的衬里材料3作为现有管道1的内表面的衬里材料。圆柱形网2从管道1的一端的开口插入，并且将未固化的衬里材料3注入到插入管道1中的圆筒形网2的一端的开口内。衬套管42从圆柱形网2的一端的开口插入，使得未固化衬里材料3向前压以便在整个圆周区域上填充圆柱形网2的网格。保持内衬管42内的压力，直到未固化的内衬材料3硬化。在衬里材料3硬化之后，衬管42从管道1中被拉出，使得在管道1的内周面上形成具有圆柱形网的固化衬里层B.（C） 2006年，JPO＆NCIPI
