Abstract: An electrolytic polishing treatment method for a nickel-based alloy workpiece made by lamination manufacturing comprises the following steps. Step (A) comprises performing a sandblasting treatment on the nickel-based alloy workpiece, followed by ultrasonic oscillation of the sandblasted nickel-based alloy workpiece in an oxalic acid solution. Step (B) comprises placing the nickel-based alloy workpiece in an electrolyte solution containing methanol, sulfuric acid, and perchloric acid and performing electrolytic polishing on the nickel-based alloy workpiece at a constant voltage after step (A). The processes of oxalic acid activation and electrolytic polishing are used to avoid the problems of residual stress and processing directionality caused by conventional mechanical processing and make the surface properties of the entire workpiece uniform.

Abstract: A method of sidelink communications by a plurality of user equipment (UE) without the control of a base station in a wireless communication system is disclosed. In one embodiment, the UE being a scheduler end is configured to allocate the resources for initial/repeated transmissions and ACK/NACK messages, and also transmit information regarding the allocated resources to both the UEs being a transmitter end and a receiver end. In one embodiment, retransmission is performed when none of the scheduler and transmitter ends has received the ACK message sent by the receiver end, so as to minimize redundant retransmission in consideration of transmission reliability. In one embodiment, retransmission is performed when at least one of the scheduler and transmitters end has received the NACK message sent by the receiver end before the retransmission timer has reached to zero, so as to minimize transmission latency.

Abstract: A continuous wave radar system comprises a substrate, a transmitter disposed on the substrate, a receiver disposed on the substrate, and an isolating device comprising a plurality of metal plates parallelly disposed on the substrate between the transmitter and the receiver for isolating leakage signal transmitted from the transmitter to the receiver. The metal plates are grounded with the transmitter and the receiver via electrical connection between the metal plates and the substrate. The metal plates are so arranged that an eddy current induced in each of the metal plates is directed away by grounding when the leakage signal passes through the metal plates.
