    • The present invention provides technology that uniformly heats and melts a plurality of solder material arranged in a plurality of locations on a board, and uniformly solders a plurality of parts to the board that are arranged in a plurality of locations on the board. A soldering apparatus includes an induction coil having a length in the longitudinal direction that is longer than the length of the board. An inner space having a size sufficient to arrange the board therein is maintained inside the induction coil. The board supporting the parts and the solder material will be positioned in the approximate center of the inner space of the induction coil. An alternating current will flow through the induction coil in this state. An alternating magnetic field will be generated in the inner space of the induction coil. Magnetic fluxes will substantially uniformly pass through the inner space of the induction coil along the longitudinal direction of the induction coil. In this way, the plurality of solder material arranged on a plurality of locations on the board may be uniformly heated and melted. The plurality of parts arranged on a plurality of locations on the board may be uniformly soldered to the board because the plurality of solder material may be uniformly heated and melted due to magnetic fluxes that uniformly passing through the board.
    • 本发明提供了均匀地加热和熔化布置在板上的多个位置的多个焊料的技术,并且将多个部件均匀地焊接到布置在板上的多个位置中的板。 一种焊接装置,其特征在于,具有长度方向的长度大于所述基板的长度的感应线圈。 在感应线圈内保持具有足以将板布置在其中的尺寸的内部空间。 支撑部件和焊料的板将位于感应线圈的内部空间的大致中心。 在这种状态下,交流电将流过感应线圈。 在感应线圈的内部空间中将产生交变磁场。 磁通量将基本均匀地沿着感应线圈的纵向方向通过感应线圈的内部空间。 以这种方式,布置在板上的多个位置上的多个焊料材料可以被均匀地加热和熔化。 由于多个焊料材料由于均匀地通过板的磁通而被均匀地加热和熔化,所以布置在板上的多个位置上的多个部件可以均匀地焊接到板上。

    • A drill rod has a fitting portion protruding toward the distal end of the drill rod. The drill rod fitting portion further encompasses a parallel male thread portion in which a minimum distance from a first axial line in a cross-section perpendicular to the first axial line is constant; and a male thread ending portion is continuous with a proximal end of the parallel male thread portion. The minimum distance of the ending portion increases as a proximal end is approached. Furthermore, the fitting portion is formed such that the minimum distance does not decrease as the proximal end is approached from a distal end thereof. Additionally, the proximal end of the male thread ending portion is positioned where a distance from the first axial line gradually increases as the proximal end of the male thread ending portion is approached from the parallel male thread.
    • 钻杆具有朝向钻杆的远端突出的配合部分。 钻杆配合部分还包括平行的阳螺纹部分,其中垂直于第一轴线的横截面中的第一轴线的最小距离是恒定的; 并且阳螺纹结束部分与平行阳螺纹部分的近端连续。 当接近近端时,终端部分的最小距离增加。 此外,装配部分形成为使得最小距离不会随着近端从其远端接近而减小。 此外,当阳螺纹结束部分的近端从平行的外螺纹接近时,阳螺纹端部的近端位于与第一轴线的距离逐渐增加的位置。
