The medicine cabinet allowed them to take the first-aided and non-hazardous drugs by themselves. The electronic system for door monitoring was assembled at the cabinet door. Users would be able to identify the drugs’ name from a voice recorder when they opened the cabinet door. The encoding circuit in the electronic monitoring system acted as the signal receiver from a micro switch when the door was opened. The decoding circuit was designed to act as signal translator from the encoding circuit to activate the voice recording circuit. The medicine cabinet was tested by the blinds in the school for the blind in Chiengmai. It was found that the integration of the encoding and decoding circuit of medicine cabinet worked effectively.

The device would absorb the latent heat from the air, and transmute to increase humidity to air steam. It consisted of 250 Watt ventilators and 35 Watt water pump. Flow rate was 2000 liter per hour and the surface area to increase humidity was 1.25 square meters. The studied parameter comprised of air temperature and relative humidity. The experiment conditions were the atmosphere temperature between 25-35 oC, humidity between 30-40 R.H., and the air flow rate was 3-4 m/s. The experiment results yielded the outlet air temperature between 23-28 oC, and humidity between 41-58 R.H. The efficiency of humidifying was 14-25 percent in range. The water consumption approximately 16 liter per day was also recorded.

Since the research project had been carried out from 2003 and 2004, it was observed that there was no 3-phase electric power for the small ceramic factory. So, the cost of electricity consumption was very high. This study searched for other methods to produce heat for ceramic kiln. The development of LPG vaporizer was developed in order to accelerate the status change of LPG from liquid to vapor. Accordingly, electricity consumption was reduced and ceramic production cost was also decreased for SMEs. The developed vaporizer produced 30 kilograms per hour of vapor. The optimum temperature for heat exchanged of boiler was 60-80 oC. It’s suitable for 3-5 cubic meter kiln size. The results from operation test were in acceptable level. Keywords Development tools accelerate the volatile gas LPG.

It is to solve the problem that people can sit anytime or anywhere they need. The shape of the chair is like a folded chair in general, but it has some pockets to keep things with. The maximum weight when design was 120kg. But after building, the weight was only 1.5kg. Sitting is a good way to relax; reduce tension, tiredness or exhaust. Whenever people have to get into agitate place, congested crowded as in a city, a market, department store or in a festival season, where is hardly to find a place to sit. The researchers have got an idea to build private chair that easy to carry with them anywhere they go. There are 2 types to use the carry bag chair: Êíҹѡ§Ò¹¡Í§·Ø¹Ê¹ºÑ ʹع¡ÒÃÇ¨Ô ÂÑ ªØ´â¤Ã§¡Òà “¾²Ñ ¹Ò¤ÇÒÁÊÒÁÒö¡ÒÃÇÔ¨ÑÂã¹Ãкº¡ÒÃÈÖ¡ÉҢͧÁËÒÇ·Ô ÂÒÅÂÑ ÃÒªÀѯáÅÐÍÒªÇÕ È¡Ö ÉÒ”

Type 2, when people want to sit, the bag can be changed by unlock it, 0and then stretch it out. It becomes a chair where people can sit. The expert engineers and the skilled tailors have tried to use the bag chair and have a performance assessment with the analyzed questionnaire of IOC. It was found that the carry bag chair is qualified and used effectively. šœµÎ £µ¡š¸É 1 Á„µo °Ê„¸ ¦³Ážµl ­µ¥­³¡µ¥ ‡ªµ¤Ážœ} ¤µÂ¨³‡ªµ¤­µÎ ‡´…°Šž{®µ …°Á…˜Äœ„µ¦ª·‹´¥ „µ¦œ´ÉŠÁž}œ„µ¦¡´„Ÿn°œš¸É—¸šÉ¸­»—ª·›¸®œ¹ÉŠ ŽÉ¹Š‹³nª¥ „µ¦­¦oµŠÁ¡Éº°ž¦³Á¤·œ‡»–£µ¡ Á„oµ°Ê¸„¦³ÁžlµÂ Ÿn°œ‡¨µ¥‡ªµ¤˜¹ŠÁ‡¦¸¥— ‡ªµ¤Á®œºÉ°¥Á¤Éº°¥¨oµ ¨³ ¦¦Ášµ‡ªµ¤°n°œÁ¡¨¸¥˜nµŠ ŗoÁž}œ°¥nµŠ—¸¥·ÉŠ ˜nĜ ­µ¥­³¡µ¥ Ÿoª¼ ‹· ¥´ ŗo‹µÎ „´—…°Á…˜„µ¦«¹„¬µ—Š´ œÊ¸ ­£µ¡„µ¦–rž{‹‹»´œ Ĝ­´Š‡¤ šÉ¸ªn»œªµ¥ °°´— 3.1 Á„oµ°¸Ê„¦³ÁžlµÂ­µ¥­³¡µ¥ ¤¸„µ¦ÄoŠµœ 2 „¦–¸ Á¸¥—Á­¸¥— ‹°Â‹ Ánœ ĜÁ¤º°ŠÄ®nÇ ¥nµœ»¤œ ˜¨µ— ®oµŠ­¦¦¡­·œ‡oµ Áš«„µ¨Šµœ˜nµŠÇ „µ¦šÉ¸‹³®µšÉ¸œÉ´Š ‡°º ¡´„Ÿn°œ¥µ¤Á¤ºÉ°¥¨oµœ´Êœ µŠ‡¦´ÊŠÂš‹³®µÅ¤n¤¸Á¨¥ „¦–¸š¸É 1 …–³š¸É°¥n¼Äœ£µª³ž„˜· Á„oµ°¸Ê„¦³ÁžlµÂ —´ŠœÊœ´ …µo ¡Á‹oµ Ÿo¼ž¦³—·¬“r ‹¹ŠÁ„·—Âœª‡·—š¸É‹³Ä®oš»„‡œ ¤¸ Á„oµ°Ê¸ž¦³‹Îµ˜´ªÂ¨³­µ¤µ¦™¡„¡µÅžÄœš¸É˜nµŠÇ ŗo ­µ¥­³¡µ¥‹³°¥n¼Äœ¦¼ž…°Š„¦³ÁžlµšÉ¸ÄoÄ­nÁ°„­µ¦Â¨³ ­³—ª„ ×¥‹³Å¤nšÎµÄ®oŸo¼¤¸Á‹oµ…°ŠÁ„oµ°¸ÊÁ„·—‡ªµ¤¨Îµµ„ ­´¤£µ¦³˜nµŠÇ ¡¦o°¤­³¡µ¥¡„¡µÅžÅ—oÁ®¤º°œ„¦³Ážlµ ¨³Áž}œ£µ¦³Äœ„µ¦¡„¡µÁ„oµ°Ê¸œ´ÊœÇ ‹¹ŠÅ—o°°„ ­µ¥­³¡µ¥šªÉ´ Ş Á„oµ°¸ÄÊ œ¦ž¼ Ä®¤…n œÊ¹ ¤µ „¦–¸šÉ¸ 2 Á¤ºÉ°˜o°Š„µ¦œ´ÉŠ „È­µ¤µ¦™Áž¨¸É¥œ¦¼žÂ 1.1 …Ê´œ˜°œ„µ¦Äo Á„oµ°Ê¸„¦³ÁžlµÂ­µ¥­³¡µ¥ „¦³ÁžlµÁž}œÁ„oµ°Ê¸œÉ´ŠÅ—o£µ¥Äœ¦³¥³Áª¨µš¸É¦ª—Á¦ÈªÂ¨³ —Š´ œ¸Ê ­³—ª„ Ť¤n …¸ o°¥»nŠ¥µ„Äœ„µ¦ž¦³„° Á¡¸¥ŠÂ‡nž¨—¨p°„ ¨oª—¹Š„¦³Ážlµ—oµœœÄ®oÂ¥„°°„ „¦³Ážlµ„È‹³ 1.1.1 …–³šÉ¸°¥n¼Äœ£µª³ž„˜· Á„oµ°¸Ê„¦³ÁžlµÂ „¨µ¥Áž}œÁ„µo °Ê¸Å—oÁnœ„œ´ ­µ¥­³¡µ¥‹³°¥¼nĜ¦¼ž…°Š„¦³Ážlµš¸ÉčoÄ­nÁ°„­µ¦Â¨³ ­´¤£µ¦³˜nµŠÇ ¡¦o°¤­³¡µ¥¡„¡µÅžÅ—oÁ®¤º°œ„¦³Ážlµ 3.2ž¦³µ„¦…°Š„µ¦ª·‹´¥ Ä®oŸo¼ÁÉ¸¥ªµŸ¼o¤¸ ­µ¥­³¡µ¥šª´É Ş ž¦³­„µ¦–r­µ…µª·µnµŠ„¨Ã¦ŠŠµœÅ¤nœo°¥„ªnµ 5 že ‹Îµœªœ 2 ‡œ Ÿo¼¤¸ž¦³­„µ¦–r—oµœ­µ…µª·µnµŠ¥œ˜r 1.1.2 Á¤ºÉ°˜o°Š„µ¦œ´ÉŠ „È­µ¤µ¦™Áž¨É¸¥œ¦¼žÂ „¦³ÁžlµÁž}œÁ„oµ°¸ÊœÉ´ŠÅ—o£µ¥Äœ¦³¥³Áª¨µš¸É¦ª—Á¦ÈªÂ¨³ ÊÒí ¹¡Ñ §Ò¹¤³Ð¡ÃÃÁ¡ÒÃÍÒªÇÕ ÈÖ¡ÉÒ ­³—ª„ Ťn¤¸…o°¥»nŠ¥µ„Äœ„µ¦ž¦³„° Á¡¸¥ŠÂ‡nž¨— ¨p°„¨oª—¹Š„¦³Ážlµ—oµœœÄ®oÂ¥„°°„ „¦³Ážlµ„È‹³ ÊíÒ¹¡Ñ ÇÔ¨ÂÑ áÅоѲ¹Ò¡ÒÃÍÒªÕÇÈ¡Ö ÉÒ „¨µ¥Áž}œÁ„µo °Ê¸Å—oÁœn „´œ ª´˜™»ž¦³­Š‡r…°Š„µ¦ª‹· ¥´ 1.

According to the research, it was found that the small material for growing plants used a small amount glue to hold it together was suitable for growing young plants. It was not suitable for the size 5 by 6 inches to grow plants until harvesting. The different materials used, have different shapes maintain. The most suitable material was coconut fluff. There was not any cost for the material used in production because they used the waste material. But the cost of labors was high or low according to the time used in production. The suggestions were to compare using materials to find the shape maintain at least 45 days that is the time for growing vegetable. And study to find the way to make it maintain shape without using any containers in order to reduce cost and reduce process. Then study if there are enough nutrients for 45 days, and to build a local pressing machine for the community. ÊÒí ¹¡Ñ §Ò¹¤³Ð¡ÃÃÁ¡ÒÃÍÒªÇÕ È¡Ö ÉÒ ÊíÒ¹¡Ñ ÇÔ¨ÂÑ áÅоѲ¹Ò¡ÒÃÍÒªÕÇÈÖ¡ÉÒ

As the Palm Oil Extracting Machine for Household was fabricated by the Department of Mechanic (Auto Machine), it could work efficiently. Accordingly, it was necessary to make a palm fruit stripper to support the extracting machine. It was also such a good way to increase the value of farmers’ products. Moreover, it provided opportunity to students to create a new body of knowledge and transfer technology to the community. The research found that the machine could work well in two steps. The first step was to clean the ripen palm fruit collected from the plantation. The second step was to separate the palm fruit from the bunch. The experiment showed that the palm stripper could strip 411.7 kilograms per hour palm fruit. The unripe palm fruit and its stalk could be made compose. The results from research would be benefit to the community.

It was used to remove the piston of 2-stroke motorcycle engine that stuck in cylinder due to lack of lubricant or auto lube. The working operation based on screw principle which allowed vertical or horizontal movement of any object while rotating the screw. When the screw rotated, torque would be applied to the screw and the magnitude overcame the friction force between the surface of the piston ring and its cylinder wall. Accordingly, the developed tool was a simple machine for removing the stuck piston from its cylinder. The results from research showed that the designed piston remover could be performed faster than the traditional methods of removing the piston. The experiment of 5 replications revealed that it required 4.67 minutes in average comparing to 6.88 minutes obtained from the traditional method in removing the stuck piston. It was concluded that developed tool yielded better operation and lower cost of service and maintenance.

Groundnuts and all parts of its plant are very useful. Groundnuts preservation is a way for value added production and a big number of agriculturists are interested to do this. The roasted groundnuts grinder was developed by using grinding drive motor size 37 by 38 by 32cm with 15.7kg weight. The principle working consists of a set of 2 pulley grind which made of brass rotate in the counter forward direction which was driven by motor ¼ HP, 200 volt. With a set of power transmission belt, it can grind roasted groundnuts 119 kg per hour. It can grind 97.6% roasted groundnuts with power consumption 0.29 units an hour. Finally it was found that roasted groundnuts can be cooked well with good small and there isn’t rancid smell in it.
