    • A molding die unit has a shell and a die. The die is located inside the shell. A die hole is formed in the die. The die has first and second portions. The first and second portions include their respective surfaces defining the die hole and facing each other. A first through hole is formed in the shell and penetrates so as to open in an outside surface and in an inside surface of the shell. A second through hole continuing to the first through hole is formed at a position corresponding to the first through hole and in the first portion. The second through hole includes a first region and a second region. The first region opens in a surface of the first portion facing the inside surface of the shell and has a first sectional area. The second region opens in the surface defining the die hole and has a second sectional area smaller than the first sectional area.
    • 成型模具单元具有壳体和模具。 模具位于壳体内。 在模具中形成模孔。 模具具有第一和第二部分。 第一和第二部分包括它们各自的表面,其界定模具孔并面对彼此。 第一通孔形成在壳体中并穿透以在壳体的外表面和内表面中打开。 在与第一通孔相对应的位置和第一部分中形成有连续到第一通孔的第二通孔。 第二通孔包括第一区域和第二区域。 第一区域在面向壳体的内表面的第一部分的表面中开口并且具有第一截面积。 第二区域在限定模孔的表面中开口,并且具有小于第一截面积的第二截面面积。

    • A plurality of resonators 50 are formed in a dielectric porcelain block 42, wherein each of the resonators 50 is formed by coating an interior surface of a through section with an interior conductor 54, thus constituting a dielectric filter 41. On a side surface 44 of the dielectric block 42 perpendicular to an open end face 43 having the through sections formed therein, there are formed protrusions 45 having a height L lower than that of the through sections. Terminal electrodes 60a and 60b are defined with the protrusions 45 taken as a boundary between the terminal electrodes 60a and 60b, and isolated from an exterior conductor 62.
    • 多个谐振器50形成在介电瓷块42中,其中每个谐振器50通过用内部导体54涂覆贯通部分的内表面而形成,从而构成介质滤波器41.在侧面44上 与形成有贯通部的开放端面43垂直的介质块42形成有比通过部的高度L低的突出部45。 端子电极60a和60b被限定为突起45作为端子电极60a和60b之间的边界,并且与外部导体62隔离。
