An apparatus is provided for synthesizing a film on a substrate in a reactor that defines an outer reaction space. By using the load planning system to simulate shipments according to a variety of package routing plans, a user of the load planning system may identify shipping routes along which certain shipments may by-pass the sorting process of regional shipping hubs. Under the control of the electronic apparatus, a control unit controls an apparatus having functions of recording and playing the broadcast programs. The circuit may compare signals outputted by each heater-thermocouple and then may produce a resultant value based on the comparison. The electric vehicle charging assembly monitors the rotational position of the cord reel to prevent unauthorized use, and to record or relay information related to the improper use or malfunction of the electric vehicle charging assembly. Thus, the longitudinal bar of the main frame is rested on the stop block, thereby preventing the main frame from being entirely rested on the ground due to an excessive rotation, and preventing the user’s back from being injured due to excessive bending so as to protect the user’s safety.
