摘要:
A catalyst filling method in a micro channel and a reformer manufactured by the method. The catalyst is filled in the micro channel using water, and unidirectional pressure is applied to the catalyst in the micro channel to fill the micro channel with high density. The catalyst in the micro channel is dried. The method according to the present invention allows uniformly filling the catalyst particles in the micro channel of the reformer with high density, increasing the reactive surface area of the catalyst particles with the fuel, thereby allowing highly efficient reforming effect.

A system and method for processing postal work using Radio Frequency Identification (RFID) apparatus. With RFID applied to the postal work, the system includes a structure for managing postal devices used in postal registration center and postal delivery center such as embedded controllers for controlling monitors, audio alarms, alarm lamps and PDAs. The system also includes middleware for managing RFID readers and message repeater adopting Java Messaging Service (JMS) . This allows exchanging data received from the RFID reader by JMS transfer method, ensuring stable asynchronous exchange of information and effective monitoring of data transferred in an entire process of postal work. This also decreases the load of the middleware in a work environment where a large amount of data is received in a short period of time such as postal work process.
摘要:
The present invention relates to a photosensitive composition comprising a triazine-based photoactive compound containing oxime ester. The photosensitive composition according to the present invention has good sensitivity, retention rate, mechanical strength, heat resistance, chemical resistance and developing durability since it contains, as photopolymerization initiator, a compound having an oxime ester group and a triazine group in one molecule and thus effectively absorbs UV radiation. Therefore, the photosensitive composition according to the present invention is advantageous not only in curing of materials for color filters, resin black matrixes, column spacers, overcoats and passivation films of liquid crystal displays, but also in high temperature process characteristics.
摘要:
A multiple RFID reader system for controlling operations of multiple RFID readers is provided. To minimize radio interference between multiple RFID readers, when a new RFID reader connects to the system, the system calculates probabilities of radio interference between the new RFID reader and already connected RFID readers and creates a radio interference logical operation list using the calculated radio interference probabilities. When it has been requested that the new RFID reader be activated, the system compares the created radio interference logical operation list with a list of currently running RFID readers and decides whether or not to activate the new RFID reader based on the comparison.

Provided are an apparatus for preparing vinyl chloride including: a pyrolysis reactor in which 1,2-dichloroethane and inert solid particles are mixed to generate vinyl chloride and hydrochloric acid; a first separator receiving the vinyl chloride, hydrochloric acid, and inert solid particles from the pyrolysis reactor and separating the vinyl chloride and hydrochloric acid from the inert solid particles; and a regeneration reactor receiving the separated inert solid particles from the first separator and regenerating the inert solid particles by burning the inert solid particles in a high temperature to remove coke deposited on the inert solid particles, wherein the restoration reactor is connected to the pyrolysis reactor to resupply the restored inert solid particles to the pyrolysis reactor, and a method of preparing vinyl chloride using the same. According to the apparatus and the method, the conversion rate can be improved, the productivity can be improved by effectively preventing interruption due to coke deposition, and the thermal efficiency can be enhanced by reusing thermal energy of sold particles heat treated at a high temperature in the regeneration reactor in the pyrolysis.
