摘要:
A method for transmitting a payload encapsulated in a packet from a transmitter to a receiver by using an Automatic Request process, in which: the receiver checks each packet received from the transmitter to detect some potential corrupted received packets the receiver acknowledges the correct or the corrupted reception of each received packet by emitting one or many acknowledgment messages to the transmitter; the transmitter resends the packets that were indicated as corrupted in the received acknowledgment messages. For at least some packets, the transmitter implements an EC-PartARQ error control mechanism including the steps of: defining a sensitive part and a non-sensitive part in the transmitted packet; checking only the sensitive parts in the packets to detect any potential corrupted received packet, a packet being considered as corrupted if the sensitive part has not been correctly received.

An active matrix substrate with a high aperture ratio is provided, which is capable of preventing electrical short circuits between pixel electrodes and auxiliary capacitive electrodes. Gate lines and auxiliary capacitive electrodes are formed on an insulated substrate. The auxiliary capacitive electrodes have holes formed therethrough. To cover the gate lines and the auxiliary capacitive electrodes, a first interlayer insulating film is formed, on which source lines, a semiconductor layer, and drain electrodes are formed. Then, a second interlayer insulating film is formed to cover all those layers. In the second interlayer insulating film, contact holes are formed to reach the drain electrodes in areas corresponding to the areas of the holes. Pixel electrodes formed on the second interlayer insulating film are connected to the drain electrodes through the contact holes.

To form a thick coating by a discharge surface treatment, a voltage between an electrode and a workpiece during a discharge is detected, and it is determined that a discharge surface treatment state is abnormal if it is detected that the voltage is reduced. With this arrangement, it is possible to accurately detect an unstable phenomenon in the discharge surface treatment, and take appropriate measures before a state of the coating and a state of the electrode are worsened due to the unstable phenomenon. By discriminating a stability of the discharge surface treatment, the coating and the electrode are prevented from being damaged.
