  • This study was conducted as a basic study for the selection of tags suitable for logistics management in the palletized unit-load unit and the development of various technologies to activate the palletized unit-load shipment of agricultural products through local APCs. Three types of passive RFID tags of UHF 900 MHz and one type of active RFID tag of 2.4 GHz band designed and manufactured through this study were used to analyze the receiving strength according to the tag's attachment location and distance of the palletized unit-load of agricultural products. In the passive RFID tag, there was a large difference in receiving strength by the tag's attachment location and a large amount of data loss depending on the distance within 30 m, whereas, in the active RFID tag, it was superior to the passive tags in terms of both receiving strength and data loss. Therefore, active tags are desirable from the perspective of multiple identification of warehouses with large spaces in relation to the application of RFID tags for palletized unit-loads of agricultural products, but the development of low-power technologies such as software wakeup power management as well as hardware to minimize battery power consumption is necessary.

  • Film printing companies have many problems during a printing process. Most of all, even an insect or dirt stick to the transparent film may cause severe errors until the end of printing job, which means big economic damage to the company. To prevent some insect-dots or dirt-dots, we have to Inspect the total area of film. However, it is very difficult to inspect the film in real-time due to the high-speed of printing that usually more than 150 m/min. A hardware based approach, for example DSP-based approach can be the one of solution candidates, but the total cost and the complexity increases the very high-level. In this paper, we suggest a software based approach, using MMX technology, to inspect the film in real-time. By Many real-plant experiments, we can see the suggest approach is applicable for the inspection of food packaging film in real-time.

  • This paper presents design and analysis of ultrasonic vibrator featuring the piezoelectric actuator. After describing a geometric configuration of the proposed vibrator, an analytical model of the ultrasonic vibrator is formulated by adopting liquid film pattern theory and wave theory. The dynamic analysis and geometric optimization are then undertaken using a software ANSYS. The optimization is performed by taking the amplitude of the tip displacement as an objective function. The fluid flow characteristics of the proposed vibrator are analyzed by taking three different fluids: water, silicon oil and ethylene-glycol. This is achieved using a software FLUENT.

  • Generally, electronic packaging designer uses HSPICE SOFTWARE TOOL to validate electric characteristics of traces layout before layout traces in PCB in hundreds Mb/s high speed digital circuits. We are in need of a plated through hole (PTH) model and a connector model to use HSPICE SOFTWARE TOOL. Those models have not been perfectly defined for HSPICE simulation. In this paper, we define a PTH model and a connector model for HSPICE simulation and discuss application range for these models. Th emodels are analytic models very applicable for HSPICE simulation and are used to analyze electric characteristic of the PTH and the connector in thetraces layout in high speed digital circuit.

  • We have developed three evaluation checklists of educational softwares for users such as, learners, teachers and parents, not for the software develops or designers. This study has especially focused on CD-ROM titles and softwares on the internet. The followings were selected as the essential attributes that the educational softwares of high quality should possess : ease of use, technical support and interest of learning for learners, educational value and smartness for teachers, packaging integrity, investment value and childproof for parents. The evaluation checklists were developed on the basis of evaluation criteria which were concretion of the essential attributes. The validity of the evaluation checklists was supported by a theoretical study for the development of ckecklists and the actual development process. The interrater reliability and the retest reliability were confirmed by statistical methods. Thus, the developed checklists can be a useful tool to evaluate educational softwares. This study will contribute to improvement of the software quality and help users in selecting educational softwares.

  • The packaging plastic manufacturing(blown film) industry has long developed in China, but most of them are small/medium-sized enterprises, and it is very rare to have appropriate operation plans suitable for their own business. The packaging plastic manufacturing industry(blown film) follows a typical Make-To-Order method, and the sequence of processing orders is very important. Waste of materials incurred by frequent conversions of production cannot be avoided, and generally, related costs incurred during conversion production are also different. Therefore, this study developed a job sequence determination model for improving operating profits using @RISK simulation software, compared and analyzed 3 actionable clustering treatment methods proposed by technical managers and field experts under the actual situation of the factory.

  • Until recently, ind ustrial designers designed the product packaging of Eletronic Media, and userInterface designers focused primarily on software design, But as computer related technology continues to evolve, this distinction has become ambiguous, As a natural consequence of these trends, industrial designers are getting more involved in user-interface design to develop interactive objects, Moreover, In the future, the whole Information of a product whIch means product packaging, marketing, training matenals, support as weIl as hardware and software will be regarded as a product, and user's entIre expenences including the material elements of product will be taken for the factors of user interface to expand the category of user interface design. The importance of interface design and its applications within industrial design has been stressed in the recent years, However researches on practical process in interface design developments have been rarely established. This paper aims to develop the interaction design process for the useful user-interface design by theoretical study and actual analysis of user-interface design.

  • In this paper, we will introduce a new corner detector for the wafer die position recognition. The die position recognition procedure is necessary for WSCSP(Wafer Scale Chip Scale Packaging) technology, decide the accuracy of post-procedure. We present a hierarchical gray level corner detection method for the recognition of the die position from a wafer image. The new corner detector divides the corner region into many homocentric circles, and calculates the comer response and the angle of direction about each circle to get an accurate toner point. The new corner detector has a hierarchical structure so it can detect comer point more quickly than general gray level corner detector.

  • Liquid filling machines are frequently used in packaging fields; however, there exists a problem in precisely measuring the quantity of the liquid. In the case where the liquid filling machine is not properly metered, there may be issues, such as the fluid exceeding the capacity or chemicals being exposed outside. In this paper, we propose a smart injection nozzle device that can solve the issues stated above. The proposed smart injection nozzle can raise the nozzle according to the water level to remove bubbles and inject the accurate amount of fluid. In addition, the efficiency of the logistics process is enhanced by the smart QR code. Through experiments using the developed smart injection nozzle device, we have noticed that the accuracy of injection capacity, nozzle position, reaction time and building data exceeded the target value. Therefore, it expected that this machine will give more production and save a lot of manpower for packaging industry.
