The objective of this fashion thesis was to study womens clothing design in party wear style inspired by Thai Lacquer Art (Lai Rod Nam) in Ayutthaya era. The outstanding points of Ayutthaya era’s Lacquer Art: appearance and pattern of lacquer decorating Tripitaka cabinet were applied in connection to Khon costumes to create and design womens clothing in elegant and tasteful party wear style. The instruments included Ayutthaya era’s Lacquer Art analysis form consisting of layout and pattern placement and color use Khon costumes analysis form consisting of costumes layout focusing on physical nature and overall work analysis. The results of this study showed as follows. The author applied Thai Lacquer Art pattern decorating Tripitaka cabinet in Ayutthaya era including Kanok Pleaw Kanok Ruang Khao Pun Pruksa and pattern in animal figures to redesign and reorganize the work. Digital printing technique was use to press the pattern on the fabric to be applied to Khon costumes structure. This study focused on the design and development of clothing that is modern while remains the identity of Thai Lacquer Art.

The damaged propeller shafts caused by the fatigue failure will be repaired by shield metal arc welding process. The service life dependeds on fatigue endurance limit of welding surface. This study was aimed to compare the fatigue resistance of two types of hard facing electrodes using the same arc welding repair process. The investigation of fatigue stress at 517 MPa in failure criteria showed that the propeller shafts repair by Flux core arc welding Process using electrode grade E110T5-K4H4 provided the approximate same service life as that using electrode grade X111-T5-K4 but lowered the repair costs up to thirty-five bath per kilogram electrode. As a result the total maintenance cost decrease 68250 baht per year.

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.

The objective of this research is to reduce waste in the production ceramics of Dadear Ceramics Factory in Lampang Province. The 7 quality control tools (7 QC Tools) were implemented including Check sheet Graph Pareto diagram and Fishbone diagram were used in analyze problem and solve the problems. It was found that most of the wastes come from burning ceramics process. The kilns and wheelbarrow has been used for a long time furthermore the equipment and parts were damaged from lack of maintenance. The non-standard of product arrangement method into the furnace were the cause of waste. Thus the researcher were improve wheelbarrow into the kilns and design a fixture to help worker to product arrangement. The results of the research which geathering data from quality inspection department. Then comparing data before the improvement (between September to December 2013) and after the improvement (between November 2014 to February 2015) the wastes are reduced from 8.97% to 0.29%. The result of improving is very efficiency because it can reduce the wastes to 8.68%.
