摘要： A lens barrel constructed of a cam slot, a lens cylinder, a memory means, a detecting means, a motor driving means and a control means. The cam slot has a discontinuous area formed in a portion corresponding to a parting line of a molding die used for molding. The lens cylinder ass a cam follower engaging with this cam slot. The memory means stores information indicating where the discontinuous area exists in the cam slot. The detecting means detects where the cam follower is positioned in the cam slot. The motor driving means makes the lens cylinder progress and retreat in the optical-axis direction by relatively driving the cam slot and the lens cylinder. The control means controls the motor driving means to drive the lens cylinder up to a position deviating from the discontinuous area when the cam follower is in the discontinuous area by comparing memory information of the memory mens with detection information of the detecting means.

摘要： A lens barrel constructed of a cam slot, a lens cylinder, a memory, a detector, a motor drive and a controller. The cam slot has a discontinuous area formed in a portion corresponding to a parting line of a molding die used for molding. The lens cylinder has a cam follower slidably engaging the cam slot. The memory stores information indicating where the discontinuous area exists in the cam slot. The detector detects where the cam follower is positioned in the cam slot. The motor drive makes the lens cylinder progress and retreat in the optical-axis direction by driving one of the cam slot and the lens cylinder relative to the other. The controller controls the motor drive to drive the lens cylinder up to a position deviating from the discontinuous area when the cam follower is in the discontinuous area by comparing memory information of the memory with detection information of the detector.

摘要： A bucket, for use on a swing-type rotor in a centrifugal separator, shaped to receive specimen holders of several different configurations. The bucket has a pair of diametrically opposite side walls having central portions displaced radially outwardly as first and second arcuate wall portions extending around a central axis of the bucket and another pair of diametrically opposite side walls having upper portions displaced radially outwardly as inverted U-shaped bearings for allowing the bucket to be suspended on the rotor. The other side walls are spaced from each other by a distance equal to or greater than the diameter of the arcuate wall portions.
