A power management unit （PMU） chip supplying dual panel supply voltage, which has a low electro-magnetic interference （EMI） characteristic and is favorable for miniaturization, is designed. A two-phase charge pump circuit using external pumping capacitor increases its pumping current and works out the charge-loss problem by using bulk-potential biasing circuit. A low-power start-up circuit is also proposed to reduce the power consumption of the band-gap reference voltage generator. And the ring oscillator used in the ELVSS power circuit is designed with logic devices by supplying the logic power supply to reduce the layout area. the PMU chip is designed with MagnaChip＇s 0.25 μ high-voltage process. the driving currents of ELVDD and ELVSS are more than 50 mA when a SPICE simulation is done.

Background: Preoperative diagnosis of peritoneal metastases (PM) is difficult in patients with gastric cancer (GC). Aims: to assess the accuracy of endoscopic ultrasonography (EUS) in diagnosing ascites and its predictability for the presence of PM in GC patients. Subjects: Consecutive patients with newly diagnosed GC from 1998 to 2004 were studied. Methods: All patients underwent EUS, ultrasound (US), and computed tomography (Ct) scan for preoperative staging and the presence of ascites. the results were compared with operative findings. the diagnosis of PM was confirmed by histopathology or peritoneal fluid cytology. Results: A total of 301 patients were recruited and in 250 patients the presence of ascites (n = 93) and PM (n = 71) were confirmed. EUS was more sensitive (87.1%) than combined US and Ct scan examinations (16.1%) and operative findings (laparoscopy or laparotomy) (40.9%) in diagnosing ascites. Sensitivity, specificity, positive and negative predictive values, and accuracy for predicting the presence of PM were 73%, 84%, 64%, 89%, and 81%by EUS; 18%, 99%, 87%, 75%, and 76%by combining US and a scan; and 77%, 94%, 83%, 91%, and 89%by operative findings, respectively. In multivariate logistic regression analysis, EUS detected ascites was the only significant independent predictor for the presence of PM (p tio 4.7 (95%confidence interval 2.0-11.2)). Conclusion: EUS is a sensitive method for diagnosing ascites which is an important predictive factor for the presence of PM in GC patients.

Design of a robust production facility layout with minimum handling cost （MHC） presents an appropriate approach to tackle facility layout problems in a dynamic volatile environment, in which product demands randomly change in each planning period. the objective of the design is to find the robust facility layout with minimum total material handling cost over the entire multiperiod planning horizon. this paper proposes a new mathematical model for designing robust machine layout in the stochastic dynamic environment of manufacturing systems using quadratic assignment problem （QAP） formulation. In this investigation, product demands are assumed to be normally distributed random variables with known expected value, variance, and covariance that randomly change from period to period. the proposed model was verified and validated using randomly generated numerical data and benchmark examples. the effect of dependent product demands and varying interest rate on the total cost function of the proposed model has also been investigated. Sensitivity analysis on the proposed model has been performed. Dynamic programming and simulated annealing optimization algorithms were used in solving the modeled example problems.

During the first welding process in manufacturing a precise seam container, the steel material must first undergo a full annealing treatment. Multilayer welding operations are conducted and then applied with refining treatment to obtain the goal by hardening. the influence of thermal refining on mechanical properties of annealed SAE 4130 by multilayer GtAW （gas tungsten arc welding） was discussed. the AW （annealing＋welding） and AWSt （annealing＋welding＋solution＋tempering） occurred with a minimum hardness value at GGHAZ （grain growth heat affected zone） due to coarse grain growth~ the hardness occurred with sudden drops between the multilayer welding, but was still larger than the minimum value at HAZ （heat affected zone）. the welded joint efficiency of the AWSt was 89.9%, with the elongation reduced to 77.2% of ASt （annealing＋solution＋tempering）. the cross section of the tensile samples both appeared with a uniform dimple-shaped structure, and however the necking for ASt was greater than that for AWSt. the impact value for AWSt was 166.5% of ASt. Moreover, from microstructure observations, it was found that AWSt had a greater tendency to ductile failure than ASt. these results can be inferred., the process of steady pressure and the initial position of the precision tube breakage HAZ. However, when stress occurs instantly, HAZ can absorb more energy, therefore the initial damage does not occur.

应用放射性磷矿粉（昆阳矿）和放射性过磷酸钙在浅色草甸土（石灰性冲积物母质）、黄褐土（弱酸性下蜀黄土母质）、及红壤（第四纪红色粘土母质）进行了盆栽试验,试验是在肥料与土壤均匀混合的条件下进行的。X-射线衍射鉴定及放射化学分析证明,磷矿粉经过反应堆处理后,其晶体构造未变,在施用时磷矿粉放射强度的衰变规律与P32相符合。试验结果说明,在含磷比较充足的浅色草甸土上,单独施用磷矿粉虽然并不使小米产量增加,也不提高小米植株中的含磷百分数,但是作物中所含的磷素,仍然有35%是从磷矿粉中摄取而来。当磷矿粉与过磷酸钙混合施用时（每盆加磷矿粉5.64克和过磷酸钙0.90克）,在红壤中,黄豆和荞麦的磷有80%以上来自磷矿粉,而来自过磷酸钙和土壤者只分别占4～7%和15%左右。在酸性黄褐土（小粉土）上施用磷矿粉和过磷酸钙混合肥料时,也起增产作用,小米中的磷有12%来自过磷酸钙,34%来自磷矿粉,54%来自土壤。在含磷酸钙363ppm的浅色草甸土中,小米所摄取的磷素只有18%来自磷矿粉,而来自过磷酸钙和土壤的各约占40%。这时磷肥没有使作物增产。当土壤与磷肥均匀混和时,在浅色草甸土和黄褐土中小米各个生长时期对土壤、磷矿粉和过磷酸钙的磷素吸收率,保持相当稳定的比例。但是在红壤中,黄豆和荞麦在生长后期所摄取的磷素,几乎全部来自磷矿粉,虽然在早期只占25—50%。用放射性磷矿粉与有机肥相混合,进行了小麦的砂培试验。一组经过培育腐解以后施用,另一组临时混和施用。结果证明有机肥的腐解过程并不能对磷矿粉的活度起增进作用。培育腐解后的混合肥料或临时混和的,既不使小麦产量较单施有机肥者有所增加,也不使植株的含磷百分数有所提高。
