    • The object of the invention is to provide a wiring board having the uniform quality at a high yield which is produced by hot-pressing and laminating on a wiring board base material a thermotropic liquid crystal polymer which is excellent as a wiring board covering material.The present invention provides a method of making a wiring board comprising: hot-pressing and laminating a thermotropic liquid crystal polymer film on a wiring board base material on the surface of which at least one layer containing a electro-conductive circuit is exposed, characterized by that a viscoelastic characteristic of the thermotropic liquid crystal polymer film is measured at a low frequency within a laminating temperature region and the hot-pressing is carried out at a temperature selected so that the viscoelastic characteristic falls within a predetermined range.
    • 本发明的目的在于提供一种以高收率产生均匀质量的布线板,其通过在布线板基材上进行热压和层压制备作为布线板覆盖材料而优异的热致变液晶聚合物。 本发明提供一种制造布线板的方法,包括:将热致变液晶聚合物膜热压并层压在其表面上露出至少一层含有导电电路的布线板基材上,其特征在于, 在层压温度区域内以低频率测量热致液晶聚合物膜的粘弹性特征,并且在选择的温度下进行热压使得粘弹性特性落在预定范围内。

    • A shield tunneling machine having incorporated therein an earth removing apparatus which comprises a tubular casing having an earth inlet at one end and a closable earth outlet at the other end, and an earth transport conveyor rotatably provided within the casing and comprising a helically twisted strip. Unlike conventional earth removing apparatus which has a screw conveyor comprising a rotary shaft and a screw blade around the shaft, the apparatus can transport and discharge earth containing large solid fragments and therefore performs the desired function even when small in diameter, i.e. in shield diameter.
