Regarding to production yield rate data during Y’2013, the yield rate was between 99.04% to 99.28% that were achieved the company target.
These information shows that the non-conforming part detection and inspection process could not detected non-conforming parts lead to inadequate improvement due to lack of feedback data and cause high sorting cost and return parts charging cost.
Field study and data collection FPCA manufacturing process was separated to front process which produced bare FPC in sheet level.

Taking into account the changes of torque transmitting characteristics with temperature increasing, the clutch control strategy should be changed to avoid the quality reduction of gear shifting and the thermal damage of clutch.
It is a free two-way wireless communications technology working in the 2.4 GHz band with low complexity, low power, low data rate and low-cost.
Meanwhile, DS1621 transfers the data of cold junction temperature to MCU through I2C bus.
After that, these data are packed as the Fig. 8 shows and be sent out through Zigbee wireless every 10ms.

It can be seen that all the strength and elongation data of the three quenching media could meet the requirements above.
However, the data of the charpy V-notch toughness for air cooling Q&T specimen were low and scattered.
Table 2 Mechanical behavior of the SA508-3 steel after Q&T (tested at room temperature) Quenching medium Yield Strength[MPa] Tensile Strength[MPa] Total Elongation[%] Reduction of area[%] Toughness[J] Water 510 655 26.5 74 190 Oil 455 615 25.0 69 130 Air 425 580 27.0 68 38,89,104 Conclusion 1.
Based on the data of mechanical properties, it’s found that the desired final microstructure of SA508-3 steel is tempered martensite, and it could be obtained by the tempering of water-quenched and oil-quenched specimen.

The feasibility of environment-friendly technology can be evaluated through fusion research of energy-environment for CO2 gas reduction.
Fig. 3 displays the TG data of Al2O3/PMMA composite, showing that the weight loss of the two samples is due to the decomposition of PMMA.
Fig. 2 SEM photograph of Al2O3 platelets Fig. 3 TG data of Al2O3/PMMA composite Al2O3/PMMA composites were in prepared two steps.
TG data suggested that Al2O3/PMMA composites are composed of 75%~85% Al2O3 ceramic platelets, which is similar to biogenic composite such as abalone shell.

The
system is an applied software, which is the integration of product information management,
recycling process management and recycling product data management, and its purpose is to help
recycling enterprises overcome the deficiency of information and management experience in the
course of recycling, improve the recycling efficiency of the waste appliances and set a guideline for
the operation and management of recycling enterprises.
Further more, by the recycling products data management and the Analysis module Statistic management of recycling products Process management MIS of recycling product The interface of users Database Basic information Use information Recycling process information Design information Decision module … Disassembly sequences Cost assessment Recycling process Input Interaction Output Fig.3 The framework of the recycling management information system Advances in Materials Manufacturing Science and Technology 686 analysis of recycling products, the decision module can set a guideline for the operation and management of recycling enterprises.
Also, to support this enterprise activity, national policies such as provision of grants or tax reduction are very important.

Ergonomic risk factors were identified by means of qualitative and quantitative data from general survey, participative assessments, and direct observations.
There was a reduction in WMSDs comprising backache and legs ache, and other OHS such as tiredness and dizziness, as a result of ergonomic risk factors being removed.

Experimental data indicate that a
decrease of about 58 per cent in kerf taper angle can be obtained under a given condition.
This permits an analytic reduction of certain integrals that express the distance traveled along a PH curve at constant or variable feedrate during one sampling interval of the CNC system.
As shown in Fig 2, the inner and outer kerf taper angle respectively are 3.32° and 2.93° at R=20mm, a decrease of about 58 per cen relative to 3.10° of straight-line (R=∞) compared with 3.65° and 2.72° by ordinary interpolator.The experimental data still indicate that the kerf taper angles on the two kerf walls in AWJ contouring are not equal in value.

Our experimental data clearly show that in the early stage, the deformation is
not homogeneous within the sample, indicating that significant softening occurred.
Thus interphase boundaries play a critical role in the grain size reduction mechanism.
