ABSTRACT The sterilization chamber is designed to sterilize the body using a filler formulation that is not harmful to the skin surface. Formulation, namely the composition of filler fluids (type, dose and amount) using substances that are safe for the body accordingly, certainly provides benefits. The use of the sterilization booth uses the correct and safe filling fluid. The sterilization chamber uses a mist nozzle sprayer (with the appropriate discharge) to spray the filling liquid so that the user is safe. This sterilization booth is named "White Box". This "White Box" research aims to design (functional and structural) and test (function test and performance test) on a system and mechanism for condensing the condensation of a humidifier that can fill the sterilization room optimally. The design method of the "White Box" sterilization booth uses a qualitative method with the following phases: (1) The preparation stage, namely the functional design and the structural design of the "White Box"; (2) The implementation stage is analyzing the use of tools and materials and making sterilization booths; (3) Post-implementation stage, namely testing the sterilization chamber, including the function test and performance test of the sterilization chamber. The design activity of the "White Box" sterilization booth was carried out by testing various variations of the prototype, including variations in the dimensions of the distribution pipe, the shape of the distribution pipe, and variations of the piping system. The validation process includes: (1) The diameter of the pipe against humidifier dew bursts; (2) The shape of the piping against humidifier dew spray; and (3) the length of the pipe passage to the humidifier dew spray.

We proposed a portable and ultra-small axial flow hydraulic turbine that can generate electric power comparatively easily using the low head of open channels such as existing pipe conduits or small rivers. In addition, we proposed a simple design method for axial flow runners in combination with the conventional one-dimensional design method and the design method of axial flow velocity uniformization, with the support of three-dimensional flow analysis. Applying our design method to the runner of an ultra-small axial flow hydraulic turbine, the performance and internal flow of the designed runner were investigated using CFD analysis and experiment (performance test and PIV measurement). As a result, the runners designed with our design method were significantly improved in turbine efficiency compared to the original runner. Specifically, in the experiment, a new design of the runner achieved a turbine efficiency of 0.768. This reason was that the axial component of absolute velocity of the new design of the runner was relatively uniform at the runner outlet in comparison with that of the original runner, and as a result, the negative rotational flow was improved. Thus, the validity of our design method has been verified.

The Development Trend

The networked collaborative design has been the development trend of modern product design, the application of which has been constrained by the data access conflicts. This paper introduced the networked collaborative design method of product based on the Vault, and network collaborative function of Inventor by using the project management. Under the assistance of the Vault, we had solved the key technology of access conflict of networked collaborative design, and realized the remote design between the members of efficient coordination. In this way, we had optimized the design ideas, shortened the product development cycles and improved productivity.

Technical specification of the spinner at the Pilot Plant of FTIP Unpad was needed to be reviewed through technical analysis and performance test. Experimental Design method of the research was carried out by on the spot observations, measurements, and recalculating machine main components. Results obtained from technical analysis showed that the machine required a driven power of 216 W, one single belt, a minimum shaft diameter of 16 mm, as well as a pin diameter at the main roller and at the pulley of 5,46 mm and 6 mm, respectively. It had a deflection torsion of 0,0460 a critical shaft speed of 1338 RPM, a bearing life of 3.227.817,96 hours, a frame deflection of 0,24 mm, and a frame welding load of 503,74 N. Sofar, the machine has fulfilled its technical feasibility. While the results of performance tests showed that the best taste sensation of the crackers was termed at an engine speed of 650 rpm at an actual capacity of 3.6 kg/h and at a power of 120 W, a specific spin energy of 120 kJ/kg, a spin yield of 97.38 %, an engine efficiency of 65.60 %, an engine performance index of 0.95 at a level of noissiness of 86.86 dBA. The data has fulfilled the performance requirement, but due to its vibration frequency of 21.44 mm/s – which was dangerous, improvements related to it had to be done.
