The old machine that is used to mix the fiber is an oval tank. Inside the tank is divided lengthwise into half and its paddle is flat and long like a file and it is installed on one side of the tank only so the flow of the fiber in the tank is not so good. There must be a person using a paddle to stir the fiber to flow inside the tank. Apart from that there was an issue that the fiber often sticks to the paddle because it is flat. The new machine is designed to have 8 circular saw blades sized Ø 10 inch to mix the leaf fiber so that it does not stick to the paddle. Apart from that the paddle is installed on both side of the tank increasing from the old machine that has only on one side in order to solve the problem about the flow of the fiber. One more issue is about bringing the fibber out from the tank. When the valve is opened the fiber cannot flow out easily because the bottom of the tank is flat. The researcher therefore design the tank to be adjustable so that it is easier to pour the fiber out from the tank. According to the experiment the boiled pineapple leaf blender can blend the boiled pineapple leaf with 30 kilograms water. The suitable speed of the blade is 500 times per minute and each blending process takes approximately 5 minutes. The time using for leaf blending also based on the paper usage e.g. for the smooth surface paper its production can follow the normal process but for the paper with rough texture the time using for fiber blending will be less.

Normally bast fibres were removed from pineapple web by wrapping the boiled pineapple leaf with nylon web and stamp on it. If using this method it will take 24 hours to stamp on 40 kilograms of boiled leaf in order to obtain clean pineapple web that is suitable for producing paper. Apart from that when pressing the fiber we need to get rid of the water as much as we can because the fiber will be weight before using to produce paper. If the water pressed out each time is not equal there may be an error about paper thickness. Moreover stamping on boiled leaf may be dangerous because the chemical substance used when boiling the leaf may burn the feet and cause wound. Currently there is a Pressing machine to separate water from pineapple fiber Rachadasak Supengcum 2010 to fix the problems mentioned above. However there is a weak point because the pressing tube is small so it can press only 1 kilogram of leaf per one time. Therefore the new machine is designed to have a pressing tube sized 30 centimeters wide and 30 centimeters long. The pressing period is 30 centimeters and the pressure for pressing is 70 bars. It takes 1 minute 15 second for one squeeze which contains 6 kilograms of pineapple leaf. It can decrease the time for pressing from the old machine by 6 times. In addition the machine is designed to have the open-close channel to bring the pressed fiber out from the machine more easily. According to the experiment to remove the bast fibres from pineapple web the most appropriate amount for each pressing is 6 kilograms. The pressing process takes 1 minute 15 second. The remaining pineapple web after the pressing is 3 kilograms

The aims of this study are (1) the adapting of women’s wear in holding inventory to a new product (2) the study of the satisfactions of women who are 25-35 years old in Bangkok about the adapted women’s wear in holding inventory. The tools for study are the questionnaires and the prototypes to accidental survey 302 women who are 25-35 years old in Bangkok and being the members from buying products of Boutique Newcity Public Co. Ltd. The fist of methods sketching of the adapted holding inventories (shirts skirts and pants) with Ruffles Godets and Transfer Printing to selection by the 5 specialists. Then adapting the top 5 selected styles. Finally surveying and analysis of the samples with percentage mean and standard deviation. The result of the study shows that most women from the sampling are single and have education in Bachelor Degree. Their occupations are in private sector with salary range between 10000 –20000 bath. Their favourite shopping place of women’s wear is department stores and buying of top 3 are pants dress and blouse. The first reason for them to buy the products is the interesting design. The overview of adapted products shows skirts are the first favourite with mean value of 3.13. Shirts are the second favourite with mean value of 3.09 and pants are the last favourite with mean value of 3.07. The conclusion of the developed women’s wear are favoured medium level.

This paper is proposed a compressor of spilt type air conditioning modification for using with variable speed drive to control room temperature. This technique is implemented by modified reciprocating compressor of 220 V single phase air conditioner 12500 BTU to 3 phase 220 volt in order to connect with inverter variable speed drive which has input 220 V single phase and output 3 phase 220V. The result of experimental is found that modified compressor can be operated in normal condition at maximum speed. The suction pressure is 65 psig discharge pressure is 250 psig and mean of motor current is 6.48 Ampere. The proposed modified compressor can be applied with conventional split type air conditioning by change the starting method from direct start online into soft start with variable speed drive

This research is about analyzing the design of floating houses including area function structure and construction materials. Floating houses design are energy saving and security. The materials must be strong and durable. Moreover the materials must be resistant to moisture because floating houses are situated over the water which causes the high levels of moisture and rust. And the risk of corrosion. The researcher recognizes that this is important. research concludes as the followings :- 1. From the designs of floating house the shape of floating house is a triangular. The structure has 3 main parts connected as space frame making the structure to be very strong. 2. The function of used area inside the floating house has been considered about ventilation in the most effective way. There are an opened windows and doors for good air flow. 3. Regarding to the use of construction materials there are comparisons between 3 types of materials in order to choose the best type which is very durable for this floating house. 4. Structure Using steel structure that enhances strength durable easy to use and demolition.
