    Abstract: A transfer chamber is provided between MOCVD reaction chamber and load lock chamber, connected to each chamber through an opening for each, for preventing the reaction chamber from the invasion of foreign gases, which may oxydize metals of MOCVD. The load lock chamber can be evacuated or filled with an inert gas, and has a door to the outside for bringing semiconductor wafers in or out. The transfer chamber is provided with a gas inlet and a gas outlet, through each of them an inert gas is always fed and drained for circulation, and also provided with a transfer mechanism therein for transferring wafers between the load lock chamber and the reaction chamber. Wafers are placed on a susceptor connected to the lid, which is driven by the transfer mechanism. A liner tube for protecting the inner surface of the reaction chamber from undesirable contamination caused by MOCVD reaction may be provided detachably attached to the lid to enclose the wafer. Each opening may be provided with shutter means for sealing each opening while the opening is not sealed by the lid. Oxygen or water vapor undesirably introduced are washed away by the flow of inert gas in the transfer chamber on the way to the reaction chamber.

    Abstract: An improved lens focusing position adjusting mechanism in which the focusing position is adjusted by changing the relative coupling position, in a circumferential direction, of a focusing ring and a drive ring fitted in the focusing lens and moved together with the focusing lens to drive a lens system. A circumferential groove is formed in the engaging surface of the drive ring or focusing ring, an adjustment belt is inserted in the groove, and the adjusting belt is positioned with respect to the focusing ring and tightened to the outer wall of the drive ring to combine the drive ring and the focusing ring into a single unit.
