Wireless communication system and wireless slave and master units used therein

In a wireless communication system, slave units such as operation switches and the like are configured such that the higher the priority level of an information signal to be transmitted from each slave unit is, the shorter a period t1 of a carrier sense to be performed before the transmission is set. Therefore, when the slave units attempt to transmit information signals of different priority levels by using the same time slot, one of the slave units whose information signal to be transmitted is of the highest priority level is given the shortest carrier sense period t1 before the transmission of the information signal, and therefore, can transmit the information signal at the earliest timing. Accordingly, by causing the slave unit which becomes able to transmit the information signal at the earliest timing to transmit the information signal, the information signal of the highest priority level can be transmitted at the earliest timing, while the other units are caused to sense, by carrier sense, the transmission, and put off transmission of their own information signals.

Multi-track magnetron exhibiting more uniform deposition and reduced rotational asymmetry

A multi-track magnetron having a convolute shape and asymmetric about the target center about which it rotates. A plasma track is formed as a closed loop between opposed inner and outer magnetic poles, preferably as two or three radially arranged and spirally shaped counter-propagating tracks with respect to the target center and preferably passing over the rotation axis. The pole shape may be optimized to produce a cumulative track length distribution conforming to the function L=arn. After several iterations of computerized optimization, the pole shape may be tested for sputtering uniformity with different distributions of magnets in the fabricated pole pieces. If the uniformity remains unsatisfactory, the design iteration is repeated with a different n value, different number of tracks, or different pole widths. The optimization reduces azimuthal sidewall asymmetry and improves radial deposition uniformity.
