Patent number: 8034217Abstract: A liquid condensation system heats a liquid raw material under a decompressed circumstance and evaporates a volatile component from a liquid surface to condense the liquid raw material. Therefore, the liquid condensation system includes: liquid condensers, each of which condenses the liquid raw material; a vacuum pump that is in communication with the liquid condensers; and a warm water circulation system as a heating source that heats the liquid raw material in the liquid condensers. The volatile component evaporated in the liquid condensers is led to the outside of the liquid condensers through vapor lines. The condensed liquid that is not evaporated in the liquid condensers is led to the outside of the liquid condensers through condensed-liquid lines. Condensed-liquid-line adjusting valves are interposed on the condensed-liquid lines, and heaters are attached to the condensed-liquid lines. A control unit controls the heaters and the condensed-liquid-line adjusting valves.Type: GrantFiled: February 7, 2008Date of Patent: October 11, 2011Assignee: Hitachi Plant Technologies, Ltd.Inventors: Yuzuru Ito, Yoshishige Endo, Hidekazu Tsudome, Fumiaki Numajiri

Publication number: 20110076200Abstract: It is made possible to scale up the throughput of a chemical plant using microreactors. The chemical plant has a liquid sending line communicating with a raw material tank at a bifurcation of raw material and a means for detecting the flow of raw material and a control valve for adjusting the flow located in the line. In each branch line to each of the multiple microreactors connected in parallel, there are provided a means for monitoring the flow rate of raw material and a means for adjusting this flow rate. A control apparatus monitors the flow rate in each liquid sending line and adjusts the quantity of liquid sent from each control valve and each pump to avoid the influence of an air bubble or deposit in each line.Type: ApplicationFiled: August 16, 2010Publication date: March 31, 2011Inventors: Hajime KATO, Kimio SAITO, Yuzuru ITO, Yoshishige ENDO, Syuuichi MORI

Patent number: 6828810Abstract: A semiconductor device testing apparatus is realized, which allows contactors to be positioned throughout the wafer surface highly accurately for uniform contact, testing a large-sized wafer, and cost reduction. A plurality of divided contactor blocks is formed with a positioning groove. The groove is used to position the plurality of contactor blocks with a positioning frame. Because the contactor blocks are divided into plurals, it is less likely that a partial surface distortion affects other portions to impair surface flatness as compared with the case where a plurality of non-divided contactors is formed integrally, and the plurality of contactor blocks can be brought into contact with a wafer to be tested uniformly. Additionally, even though abnormality is generated in a part of the contactor blocks, only the part of the contactor blocks is replaced. Therefore, replacement costs can be reduced as compared with the case where a plurality of non-divided contactors is formed integrally.Type: GrantFiled: July 30, 2002Date of Patent: December 7, 2004Assignee: Renesas Technology Corp.Inventors: Masatoshi Kanamaru, Yoshishige Endo, Takanori Aono, Ryuji Kohno, Hiroya Shimizu, Naoto Ban, Hideyuki Aoki
