The present invention discloses a pump-type autoclave system and a providing method for steam and pressure thereof, wherein the pump-type autoclave system comprises an autoclave, a steam providing device and a compressor, said steam providing device comprises a water storage container and a heating device used for heating said water storage container, said water storage container, the compressor and the autoclave are connected through a pipeline to form a closed loop, an inlet of the compressor is connected with a steam output port of the water storage container, an outlet of the compressor is connected to a steam input port of the autoclave, and a condensate water drain outlet of the autoclave is connected to the water storage container. The present invention uses the compressor to depressurize an intermediate-low temperature water source to obtain steam, and the steam is pumped into the autoclave and condensed to release heat to obtain corresponding temperature and pressure. Since the present invention fully utilizes a great amount of low-cost intermediate-low temperature heat sources obtained from natural, industrial or living waste heat to provide needed high temperature, steam and pressure to the autoclave system, the energy is saved.

A semiconductor device has a substrate and conductive layer over the substrate. A resistive element is formed between first and second portions of the conductive layer. A plurality of semiconductor die each with first and second bumps is mounted to the substrate with the first and second bumps electrically connected to the first and second portions of the conductive layer. A test current is routed in sequence through the first portion of the conductive layer, through the first and second bumps, and through the second portion of the conductive layer until continuity failure of the second bump. The test current originates from a single power supply. The test current continues to flow through the resistive element after the continuity failure of the second bump. The continuity failure can be detected by sensing an increase in voltage across the second bump.

A method for vertically grounding and leading down form a center of a composite pole tower includes the following steps: extending a ground down-leading wire from a center of a ground wire cross arm which is made of metal and is positioned on top of the pole tower, wherein the ground down-leading wire is vertically leaded down to the earth form the center of the composite pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is extended from the center of the composite material and is directly connected to the metal pipe. The method utilizes the advantage of the insulating intensity of the wall of the composite pole tower and enhances the insulating intensity of the transmission line on impact of lightning. The ground down-leading wires are prevented from short-circuiting with the tower body of the composite pole tower, so that advantage of the insulating property of the composite material of the pole towers is realized. Since the ground down-leading wire is penetrated through center of the pole tower, so that the ground down-leading wires are not exposed and are prevented from destroying by external force. And also the method is easy and simple for application.
