In this paper, we have attempted to analyze current situation and the problem of domestic and overseas harbor container delivery & cargo work automation centered around major harbors and to suggest effective way to deal with the issue in order to improve the productivity of container cargo work per crane, the major index of productivity of high value-added shipbuilding industry. In particular, we have suggested the way to realize effective automation system that can improve the efficiency of harbor container delivery & cargo work through the development of high-tech measuring automation technology using microwave radar and applied design that have broken away from traditional automation system and traditional problems such as dependence on manual work and the problem of laser method in which workers cannot identify laser beam under sunlight and workers’ eyesight can be weakened by being exposed to laser beam.

Micro-factory has many advantages but few examples of the commercialization. Because productivity and yield are less considered in micro-factory research. The micro-factory must also ensure productivity and yield in order to be commercialized. In this study commercialization of assembly micro-factory for phone camera lens module is a main goal.

Linear vibrator is one of the core parts for a smartphone. In this study, we suggest micro-factory design for manufacturing linear vibrator. The micro-factory is designed to be consisted of four main assembly machines which are including cover assembly, weight assembly, plate assembly and total assembly. Cycle time of the factory is expected to be about 8 sec.

An alignment error is occurred certainly when parts are assembled. In general, this alignment error is corrected using measuring system and position control. In this case, an assembly machine has a high stiffness that makes a size of machine huge. The purpose of this research is invention of the module that can adjust one part to the order part automatically. The module that has a function of self adjustment only takes a stiffness in assemble direction and can be moved freely in the other direction so this function makes a self adjustment. The self adjustment module reduces the tact time and also diminishes the inferior goods and makes a size of machine small. A self-adjustment module is applied to an assembly machine that assemble a lens module for phone camera.

According to the ubiquitous times that is new important topic, the miniature is demanded in the industry at large. The high accuracy and accumulation make the assembly equipment and the production equipment huge from the size of view. The huge equipment brings about the expensive price of the equipment, a low flexibleness and a low productivity. It makes the manufacturing equipment huge that the accuracy only depends on the mechanism stiffness. The position of two assembled parts is transformed with the global coordinate system whose datum is machine coordinate system. The purpose of this research is invention of the module that can adjust one part to the order part automatically. The module that has a function of self adjustment only takes a stiffness in assemble direction and can be moved freely in the other direction so this function makes a self adjustment. The self adjustment module reduces the tact time and also diminishes the inferior goods and makes reconfigurable machine in μ-part assembly.

Cellular phone camera lens is produced by plastic injection molding process. Plastic injection mold has the gate through that lens mold is filled by molten plastic. Mold gate destroys the lens symmetry so lens has other special quality according to the orientation. Multi picker that can control the pitch has been introduced for productivity elevation. But the multi picker can not control the rotation. In this paper multi picker for lens module assembly is designed to control lens orientation and the pitch simultaneously.

This paper introduces the case study on development of airbag safety sensor by supporting convenience for driver. Passenger Disable Switch(PDS) is desigend and evaluated by simulation process and operating test. And also, many related sensors were supported for performance test of PDS. The reliability of PDS was analyzed for safe operation and application in a moto vehicle.
