This research aims to study the development of the Para rubber press machine with wrought pattern for continued 2-year project. Used natural Para rubber mixed in ta-Kuong by normally practical Para rubber farmers to evaluate the rubber press machine. It has developed the 11 roller the 3 plain duo sets of normal press rollers and the 2 duo sets of wrought rubber press rollers with the induction motor at 1430 rpm. The rotating transmission based on belts and chains. The evaluated results produced the dried Para rubber sheets thickness at 3.75 mm. on average as standard market need. From a robber sheet with enough patted on with a worker to carry the ta-Kuong to a top tray and a rubber press man to put the Para rubber piece to a machine on average the completed 185 wrought rubber sheets per hour in shorter time.

The purposes of this research were to study semi-automatic versatile carpet weaving data of central region villagers studies problems and requirement in the semi automatic versatile carpet weaving to be effective fulfill requirements for the most weavers and led the data were to study analyze to create prototype of a semi automatic versatile carpet weaving to develop household textile products in culture that led to the ASEAN Economic Community and lead the knowledge to transfer technology by workshops. This research was the development of experimental research by fieldwork survey from 25 Nam Tao Temple sampling of semi automatic versatile carpet weaver groups in top central at Tambon Wat Nam Tao of Maharat district in Ayutthaya province and choose the specific type with the weaving group and semi automatic versatile carpet weaving from 25 Nong Ngu Hau weaver groups at Tambon Bang Pra Khru of Nakhon Luang district in Ayutthaya province. Total weaver groups who used this carpet weaving jacquard were 50 persons. Results indicated that testing for the satisfaction efficient of villagers were satisfied to the semi automatic versatile carpet weaving jacquard in period that can woven more quickly. Including setting the reel head to stand on the warp by the head reel of carpet loom and the carpet roll can make carpet in 90 centimeters width and applied to household textiles such as carpet rugs wall rugs and decorative carpet. The semi automatic versatile carpet weaving jacquard can weave 4 hooks. They were made the minute patterns exquisitely and various woven. They have added the convenience of a device to lock the both sides of warp reel head and the jacquard structure were increased strength with a square box steel and the Z. It can also adjust the space of the seat movement when weaving according to individual aptitude. It can be moved easily and reduced the lack of warp yarn. It was set easier in new warp yarn by the hooking after setting the warp yarn jacquard was finished. It was convenient to roll the finished carpet weaving by using lever handle to simultaneously rotate on both sides of gear axis. Using a foot pedal lever to raise the hooks raise the sway hooks to lift up follow to the weaving rhythm. It was production costs close to the price of the similar carpet the effective yield rapidly and worth. It was suitable for the beginner weavers or a new person who had basic woven would be weaving rapidly and the carpet weaving quality was good. Due to its rotating axis and lock system were made of cogs that helped to lock the beater or comb teeth for solidness and strength to handle and help facing fabric regularly. Summary this research was is related to the methodology technique and carpet weaving process. The essential was to reel the warp yarn and set the hooks that was minuteness in the deeply technical promotes the concept to develop the semi automatic carpet weaving with electrical system and motor to help labor saving able to reduce and solve period problems too much. So the semi automatic versatile carpet weaving design will be the basic of knowledge direct that can lead to the development of devices patterns and cultural household textile products leading to the ASEAN Economic Community in the next occasion.

The objectives of this research are to propose a proper model for detecting defective machines in auto parts factories to apply the proposed model to the defective product data and to investigate the factors influencing on the machine producing defective products. A Bayesian hidden Markov model (HMM) is adopted. The results show that if the number of defective products increases the machine will be in the hidden bad state. The probability of changing from a hidden bad state to a hidden good state is higher than the probability of changing from a hidden good state to a hidden good state. The highest probability that the machine will be in a good state is at the work process 4 followed by 1 3 and 2 respectively. The highest probability that the machine will be in hidden good state is at the Worker no. 10 followed 9 3 12 7 2 1 6 11 4 8 and 5 respectively and The highest probability that the machine will be in the hidden good state is at the product type 1 followed by 2 and 3 respectively.

The purpose of this research was to construct the rotating bending fatigue testing machine for metal material to find out the built-in machine performance and compare it with machines that meet international standards. The machine built into a compact machine using weight knob for a heavy load in testing. It can test the force range 50-300 Newton (N) the motor is a 1 HP transmitter with a speed of 2800 rpm. Start by pressing the Start button to release the weight that sends power to the workpiece and attend a sensor counting is available to detect the lack of testing material. For the efficiency performance of the machine uses 10 piece steel shafts diameter of 8 mm according to the standard of the material fatigue tester by independent end bend rotation. For testing to compare with the test international standard machine also uses 10 piece steel shafts using force 150 N. For the analysis to test statistical hypotheses with the Minitab computer program at the significance level of 0.05 it was found that the values obtained from be made the rotating bending fatigue testing machine for metal material there is no difference with standard machines from statistically significant. All values are within the set limits. In conclusion the machine was created to be as effective as the international standard machine.

This research was developed from the old version of the banana slicing machine for slices a banana in sheet-form longitudinal axis only by designed constructed and tested a new version of the banana slicing machine for slices a banana in sheet-form longitudinal and horizontal axis in flat-shape and curly-shape and adjustable sheet-thickness at between 1-2 mm. The new version of the machine would consist of a pressure plate over the feeding channel. The feeding channel could support for 5 fruits of a banana in the longitudinal laying and support for 10 fruits in the horizontal laying. The blade was installed on a drum and the tray was inserted under the drum for finished products. Electric gear-motor was used to drive the drum. The overall dimensions of the machine ware 0.56m (width) 0.64m (Length) 1.38m (High). The experimental was sliced by the machine at 1.5 mm thick in flat-shape and curly-shape can be summarized; the average rate of slide was 167 kg/hr. The average tolerances of sliced was ±0.02 mm the average deviations percentage of sliced was ±1.05 and the average power consumption of the machine was 0.23 kWh. The machines were used by targeted communities with production costs of about 4.78 million baht/year will lead a net profit to 5.97 million baht/year and the payback period of about 0.82 years.
