Aspects of this invention include a downhole assembly having a non-contact, capacitive coupling including first and second transceivers deployed in corresponding first and second downhole tool members. The capacitive coupling is disposed to transfer electrical signals between the first and second transceivers. In one exemplary embodiment, the capacitive coupling is configured to transfer data and power between a substantially non-rotating tool member and a rotating tool member, for example, the shaft and blade housing in a steering tool. Exemplary embodiments of this invention provide a non-contact, high-speed data communication channel between first and second members of a downhole assembly. Moreover, exemplary embodiments of the invention also provide for simultaneous non-contact transmission of electrical power between the first and second tool members.

The invention relates to an epitaxial wafer tray for an MOCVD (Metal Organic Chemical Vapor Deposition) reaction cavity and a support and rotation connecting device matched with same. When the tray is mechanically loaded and unloaded, and a rotating shaft projecting outward from the center of the bottom of the tray is inserted into a counter bore on the top of a drive shaft perpendicular to the rotating shaft. Respectively arranged contact surfaces parallel to the surface of the tray or contact surfaces on the corresponding side face are used for supporting the tray, and the friction transmission between the contact surfaces is used for driving the tray to rotate when the drive shaft rotates. The friction transmission is changed into contact transmission by arranging an axial locating slot and a locating key, the rotation of the tray is ensured to be consistent with that of the drive shaft, and the security of the tray under middle-high speed long-term rotation is improved. The projecting tray rotating shaft is easy to process the surfaces contacted by friction, the entire thickness of the tray is not increased under the condition of ensuring the mechanical strength of the corresponding part on the tray, and the heat capacity of the tray is reduced. Thus, the time required by heating and cooling the tray is shortened, and the production efficiency is improved, which is beneficial to quick temperature adjustment and control required by epitaxial reactions.
