摘要:
A Radio Resource Control (RRC) message transmission method and apparatus for a wireless communication system operating in TTI and acknowledge mode is configured to reduce interruption time by minimizing retransmission times of RRC message. The message transmission method for a wireless communication system includes generating, at a transmitter, a message; transmitting the message two or more times consecutively from the transmitter to a receiver; analyzing, at a receiver, the message transmitted by the transmitter; transmitting an acknowledge message or a negative-acknowledge from the receiver to the transmitter depending on the analysis result; and terminating, at the transmitter, a retransmission process of the message upon receipt of the acknowledgement message.

摘要:
A nano-size lead-free piezoceramic powder and a method of mechanochemically synthesizing the same are provided. The nano-size lead-free piezoceramic powder can have a basic component of (KxNa1-x)NbO3, where x ranges from 0 to 1. A weight ratio of a milling ball to a raw powder can be set, and then the milling ball and the raw powder can be provided into a milling container at the set ratio. Nano-size lead-free piezoceramic powder can be mechanochemically synthesized using a high-energy ball mill device.

摘要:
An injection mold (1) may include: an outer block (100) that is mounted and fixed to an injection molding machine and divided into an upper mold (110) and a lower mold (120), an inner block (200) composed of an upper block (230) and a lower block (220) that are replaceably mounted on the upper mold (110) and the lower mold (120), respectively; a metal core (300) mounted in the inner block (200) and has a cavity (310) for forming a molded product (10) with a molded portion having a size of tens to hundreds of micrometers; an ejector (400) coupled to the inner block (200) and removes the molded product (10) in the cavity (310) by moving straight; a driving unit (500) disposed inside the lower mold (120) is moved up/down by hydraulic pressure or pneumatic pressure supplied from the outside, and drives the ejector (400).
