摘要:
A linear motion guide unit is disclosed in which an end cap of a slider has a tube therein to feed even minor amounts of lubricant into a circulating circuit for rollers with no lubricant leakage, making sure of positive lubrication irrespective of working orientations or postures of the linear motion guide unit. A flexible tube made of fluorocarbon polymers is installed in the end cap to run from a lubricant inlet to a turnaround passage, thereby providing a lubricant-supply passage. A distal end of the tube fits into a three-way member made open to the turnaround passage on a spacer part, which is nested inside the end cap.

摘要:
A wafer transferring method for transferring wafers between a cassette and a boat having grooves to hold the wafers, comprises the steps of providing an identification mechanism for positional alignment on the boat in advance, detecting the identification mechanism, and aligning the boat to a predetermined position based on a detection result and transferring the wafers from the cassette to the boat. A wafer transferring apparatus comprises a loading device for extracting wafers from a cassette and transferring the wafers onto a boat, a detection device for detecting an identification section provided on the boat in order to identify a wafer transferring position on the boat, and a control device for acquiring the wafer transferring position on the boat based on a detection result attained from the detection device and controlling a mutual position between the boat and the cassette to come to a predetermined position.
