摘要： A squirrel-cage rotor and a production method thereof, the rotor having conductors with sufficient strength. In the invention, conductor particles are sprayed onto a core and/or conductive bars in a solid-state. As a result, in the coating material, the enlargement of the crystal grain of the conductors is significantly restricted, whereby conductive end rings are connected to the core and/or the conductive bars. Since conductor particles do not melt, a gap formed by thermal contraction when the conductor melts between different kinds of members is prevented from being formed. Therefore, the deterioration of the conductor may be limited, and the conductor may have sufficient strength. The reliability of the rotor is improved.

摘要： A novel prefabricated tile panel consisting of a rectangular or square substrate board having side-long rectangular convex and concave portions arranged regularly by turns around the sides of the rectangular or square shape and a multiplicity of tiles arranged regularly and bonded onto the substrate board is provided. The concave portion and convex portion are of specified dimensions, respectively. The convex portions are protruded and the concave portions are set back from the tiles arranged and bonded in a rectangular or square shape. Thus, the prefabricated tile panels can be assembled without trouble by inserting the convex portions of one panel in the concave portions of other panel or panels for installation of the tile panels. The prefabricated tile panel can be produced efficiently by using a frame which has matrices for tiles arranged at a tile-joint interval in a rectangular or square form and is equipped with guide members around the frame for accepting the substrate board in a predetermined position.

摘要： A gasket having a concentrically waved metal sheet, i.e., a core member, which has a sheet of sealing-property layered and bonded on each of its opposite surfaces. The gasket has an enhanced adaptability of the sheet material and enables the thinner sheet to be used and at the same time makes it possible to ensure a stable sealing-property for a long period of time with a low to a high fastening-load applied. The metal sheet has valley portions, which were conventionally vacant gaps, and are filled with powdered sealing member to be embedded from the beginning. Therefore, the sheet at the valley portions of the metal sheet that conventionally could not be compressed with a low fastening-load applied can be compressed and even with the low fastening-load applied can secure a fastening surface-pressure over the entire surface. Further, since it is possible to suppress the deformation of the sheet in quantity, which was conventionally large, a sheet made of not only the high-fluidity material but also the low-fluidity material can be used as well as the thinner sheet.
摘要翻译：具有同心波状的金属片，即芯构件的垫圈，其具有层压并粘合在其每个相对表面上的密封性能片。垫片具有增强的片材的适应性，并且能够使用较薄的片材，并且同时可以在施加低至高的紧固负荷的情况下长时间确保稳定的密封性。金属片具有通常为空隙的谷部，并且填充有从一开始就嵌入的粉末密封构件。因此，通常不能用施加的紧固负荷而不能压缩的金属板的谷部处的片材可以被压缩，并且即使施加的紧固负载也能够确保整个表面上的紧固表面压力。此外，由于可以抑制通常较大的片材的变形，所以可以使用由不仅高流动性材料制成的片材，而且还可以使用低流动性材料的片材以及更薄的片材。

摘要： An induction motor capable of obtaining a high power characteristic in a wide range without producing induced voltage. A winding for each phase is composed of a plurality of winding components having the same number of turns. When high torque is needed with low speed rotation, a Y-connection in which winding components for each phase are connected in series is formed as shown in FIG. 2a. For medium low speed rotation, a &Dgr;-connection in which winding components for each phase are connected in series is formed as shown in FIG. 2b. For medium high speed rotation, a Y-connection in which winding components for each phase are connected in parallel is formed as shown in FIG. 2c. For high speed rotation, a &agr;-connection in which winding components for each phase are connected in parallel is formed as shown in FIG. 2d. Using the entire winding for each phase, the number of turns is decreased stage by stage to switch from low speed rotation to high speed rotation. Since there is no unused part of windings, there is no problem of induced voltage. A fall in power at the time of switching the winding formation can be restrained, so that a high power characteristic can be obtained in a wide range.

摘要： Windings of each phase in a three-phase AC motor are independent of one another. A motor control unit gives, to windings of each phase (U, V and W-phase), currents (IU, IV, IW) obtained by adding, to a fundamental sine wave current, a current having a frequency which is three times as high as that of the fundamental sine wave current. That is, IU=I·sin ωt+Ia·sin 3ωt: IV=I·sin (ωt+⅔π)+Ia·sin 3ωt: IW=I·sin (ωt+{fraction (4/3)}π)+Ia·sin 3ωt Also, amplitude Ia of a current having a frequency which is three times as high as that of the fundamental sine wave current is set to a predetermined value smaller than amplitude I of the fundamental sine wave current.

摘要： A method and apparatus for controlling an induction motor having at least high speed windings and reduced speed windings divides the reduced speed windings into first and second portions. The first and second portions of the reduced speed windings are electrically connected in series and a voltage is applied to the first and second portions of the reduced speed windings when it is desired to operate the induction motor at a reduced speed. The first and second portions of the reduced speed windings are electrically disconnected and a voltage is applied to the high speed windings when it is desired to operate the induction motor at a high speed. The induction motor has three sets of windings extending from a middle region, each set of windings having an inner winding toward the middle region and an outer winding away from the middle region. According to one aspect, a first changeover circuit is electrically connected to each set of windings, between the inner and outer windings for applying a voltage to the outer windings when it is desired to operate the induction motor at a high speed. A second changeover circuit is electrically connected to each set of windings, toward the middle region from the inner windings for applying a voltage to the inner and outer windings when it is desired to operate the induction motor at a reduced speed. It is thus possible to change from a Y configured winding connection to a .DELTA. configured winding connection.

摘要： A gasket having a concentrically waved metal sheet, i.e., a core member, which has a PTFE sheet or an inorganic sheet of sealing-property layered and bonded on each of its opposite surfaces. The gasket makes it possible to ensure a stable sealing-property for a long period of time with a low to a high fastening-load applied. The metal sheet has valley portions, which were conventionally vacant gaps, and are filled with powdered sealing member to be embedded from the beginning. Therefore, the PTFE sheet or the inorganic sheet at the valley portions of the metal sheet that conventionally could not be compressed with a low fastening-load applied is compressed and even with the low fastening-load applied can secure a fastening surface-pressure over the entire surface. Further, since it is possible to suppress the deformation of the sheet in quantity, which was conventionally large, the PTFE sheet or the inorganic sheet each of low-fluidity are arranged so as not to be broken with a high fastening-load applied and the thinner PTFE sheet or the thinner inorganic sheet can be used.
