The purposes of this study were to study amount modified starch substitution by rice canned mackerel in tomato sauce seasoned with black pepper ratio at 15:85 20:80 and 25:75 percentage. The results showed that the best formulation of product was rice flour (percentage) 20:80 because sauce in can were red orange pH of sauce was = 6. The result of the study showed that the physical and chemical attributes of product canned mackerel in tomato sauce seasoned with black pepper compared with control. Found that canned mackerel in tomato sauce seasoned with black pepper of dark orange more than control. pH = 6.05 – 6.15 were similar moisture protein fat and carbohydrate content but the differences in ash content. The consumer acceptability indicated of target consumer accepted the product consumer need to buy this product 79% like moderately this product 72% and suitable price about 15 bath/can. The product of storage 6 mouths and not detects mesophilic aerobic bacteria and thermophilic aerobic bacteria.

This project report proposes a design and construction of model of protection equipment for three-phase transmission line by voltage relay for protect. By protection equipment can protect the transmission line from over voltage and under voltage on the transmission line The objective of design and construction model of protection equipment for three-phase transmission line. The objective for construction model of protection equipment for three-phase transmission line. For understand power system protection principles. And understand using to protection equipment for three-phase transmission line correct. From experimentation model of protection equipment could protect over voltage and under voltage on the transmission line

This thesis is duplicated of the controlled of the AC. Three Phase Generator with case study and analyze of the characteristic of generator in various operating conditions. By the model works of the actual use in establishment generator this is using generator for backup electricity from main feeder. We have the functional testing of start or stop for check store the characteristics in different conditions at that time. Load distributing of generator for check store parameters. The parallelization of generator into the system in case of emergency while the failure of the mains system. The degradation of generator off the system when main is back to normal or the emergency stops of generator in case of accident during the operation.

Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as an alternative choice of testing. Regarding to the problems as addressed above this project was aimed to design and test crash boxes which come in various structures; simple type corrugated type and honeycomb type of crash box. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. Numeric simulation and static test methodology of front collision were applied for these tests in reference to USA NCAP standard for automobile collision test. Testing all types of crash boxes indicated that the corrugated type was able to absorb energy at 2.8% and 5.9% higher than honeycomb type and rectangular type respectively. This is capable to pickup stress and strain continually and effecting to more energy absorb than another type. Additionally this corrugated structure is feasible and suitable for crash box design in automotive manufacturing.

Nowadays the automotive industry in Thailand has been widely growing. Brake pad is one of the automotive products that play a vital role in automotive industry because it is the most critical seeurity part. Consequently testing products for quality are extremely requested. However the precise equipment and function tests which show the real effects are not available enough and cost a lot. Therefore they cannot response to the deman in the automotive industry development. In this study the frictional test jigs for friction measurement JIS K7125 [5] and the clutch facings for automobiles JIS D4311 [6]. A study of the frictional test emphasizes on the static friction (μs) and kinetic friction (μk) in different condition. There are 3 specimens of brake pad supposted by the industry company. These specimens were tested and the results from the pin-ondisk and those from the friction testing were compared. The results revealed the correspondence of the two-sided results but the pin-on-disk’s friction coefficient is more than the friction testing’s friction coefficient by 19.56%. Moreover the coefficient of friction varies according to the temperature Besides the static friction (μs) is likely more than kinetic friction (μk) and tends to differ considerably under high pressure condition.
