The objective of paper is to design and develop solar hybrid for common usage heat energy between sunshine and heater The technology improvement of integrated solar dryer cabinet aims to prove that the solar energy for thermal purpose is most useful alternative device for energy conservation which helps environment and pollution protection. It can also be an effective equipment for industrial drying process of herbal plants and products in term of dehydration humidity reduction and fungus termination. The use of solar dryer cabinet can serve the high demand in the market of Thai herbal products which some of which are also used as detoxification. Solar Hybrid Energy Oven choose between infrared heater and DC heater. The outer structure of solar drying cabinet is made of aluminum sheet of 60 cm. wide 60 cm. long and 80 cm. high. The inner box is coated with black paint. The experimental process and data collection of solar radiation was carried out for 15 days. The humidity value measurement was conducted during a 5-hour drying process with data collection at every 20 minutes. The herbal plants used in the experiment are lemongrass pandanus citrus hystrix leaf red paprika and gotu kola. The data collection hours are from 10.00 am to 15.00 pm and the finding shoes that the highest temperature in the cabinet reaches 99 degree Celsius. The fastest dehydrated and dried process is pandanus whose initial humidity value is 589.6 % dry basis and humidity mean after drying process is 3.4 % dry basis. Lemongrass contains the second highest initial humidity value which is 566.6 % and humidity mean after drying process is 3.3 % dry basis. This indication confirms that the technology of solar energy combined with infrared heater cal most effectively generate the heat in the cabinet to serve the drying process.

This research is to study the cutting tools product in reverse engineering for turning milling and drilling included Tool holder Arbor and Insert tool. It is sampled the imported cutting tools from three areas worldwide composed with Sweden United State of America and Japan. The study emphasis in Arbor 136 mm. (6 tooth) Arbor 63 mm. (4 tooth) the changeable Insert tool typeTool bolder 20 mm. and Tool holder for turning. The result is found that Tool holder materials has the mixture of 0.387-0.437 %C hardness is 39.36-53 HRC which was full hardening. The price of Arbor (6 tooth) surveyed from four brands maximum is 22350 Baht and 2.41 times of price differentiation. The price of Arbor (4 tooth) surveyed from two brands maximum is 19000 Baht and 0.1-0.5 times of price differentiation. The price of Tool holder surveyed from three brands maximum is 14300 Baht and 0.15-0.55 times of price differentiation. And the price of Tool Holder for turning surveyed from four brands maximum is 1900 Baht and 0.5-1 times of price differentiation. The provider set up Tool holder and Insert tools will not be compatible together for marketing strategy. There are not much key player providers so there is no strong competition. The provider forces to distribute a set of 10 Insert tools and the most of Tool holder is Hardening and quenching not less than 39 HRC. The metal removal might be necessary use high technology and precision CNC Milling Machine. Therefore the study will lead to design and produce the prototype of cutting tools complete set which is compatible with Insert tools in all processes for turning milling and drilling. This cutting tools complete set differentiates from others because it helps to reduce costs reduce times and work comfortable. The development of compatible cutting tools complete set is the approach to reduce costs and times of work decrease maintenance costs and it will be the foundation to development of multi-function cutting tools complete set in place of the imported cutting tools.

Thailand is a well known country where jewelry is produced to export. The process of jewelry production needs many special skills and efficient machines. Moreover the preparation of plaster is also important in producing jewelry. This requires various stages and takes more time to do. However these problems can be eliminated by knowledge in engineering. Therefore this study aimed to develop the vacuum mixer for mixing Investment for jewelry production. The vacuum mixer consists of 12 Hp 220 volts ac electric motor with the gear which has 1:40 dimension. The whole body of the vacuum mixer is made of stainless steel. The pot for mixing the Investment is 21 em. wide and 31.5 em. high. The tub at the base for placing the pot is 29 em. wide and 21 em. high. This base is equipped with a 20 m3 per hour vacuum ventilator and a vibrating motor. This vacuum mixer is operated by the electric motor which transmits power into gear. Then the gears drive the belt to make the blade stiring the Investment and water in the pot until they are well mixed together. Then the mixture is forced to the tub at the base by the valve while the air is sucked up and the mixture of the Investment is cured until all bubbles are disappeared from the mixture. After experimenting the result revealed that the use of the vacuum mixer can reduce the steps in preparing the plaster from 8 steps to 4 steps. It can also save 52% of time allotted.

Blends of R22/R152a/R124 have been proposed to replace R12 in refrigeration systems.In this research work a technique to simply evaluate thermodynamic properties of refrigerant mixtures has been developed from Raoults Law.the method has been approached to evaluate the properties of the refrigerant blends avalable in the market such as MP39( R22/R152/R124 53/13/34)MP52 (R22/R152a/R124 33/15/52)and MP66 (R22/R152/R124 61/11/28) .The results agree well with those given by the manufacture within 5 % error The method has also been used to evaluate the properties of the ( R32/R125/R134a 23/25/52)refrigerant agree wall with those given from the manufacture with in 3 % error The thermodynamic property dlagrams of these refrigerant blends are also proposed.

The Products Development of Crafting Herbal Soap Carved for OTOP Of Tambon Prakhonchai Amphur Prakhonchai Burirum Province” aims to study the development of the Herbal Soap Carved products which made from a household waste soap by applying to indigenous..knowledge.
