摘要： An apparatus for preparing an ultra-thin specimen with a polishing wheel is developed. The apparatus includes a base, a holding unit mounted on the base and having a movable part for supporting the specimen, and an adjusting assembly attached to the base for adjusting an orientation of the specimen relative to a top surface of the polishing wheel by providing a fine movement during polishing. The movable part of the holding unit is advantageously moved away from the adjusting assembly to enlarge the latitudinal cross-section of the apparatus so as to increase the precision of the orientation.

摘要： An automated optical inspection system for the runout tolerance of circular saw blades comprises a rotating device, a first and a second optical inspection module, and a computing device. The rotating device is used to rotate a circular saw blade. The circular saw blade includes multiple teeth, and each tooth has a side and a back. The first/second optical inspection module is used to capture a side/back image of the tooth. The computing device activates the rotating device to rotate the circular saw blade, and activates the first and the second optical inspection module to capture the side image and the back image of each tooth upon rotation of the circular saw blade. The computing device performs a radial-position-calculating procedure according to the side images, to obtain an amount of radial runout, and performs an axial-position-calculating procedure according to the back images, to obtain an amount of axial runout.

摘要： A fabrication method for a transmission electron microscope (TEM) slide is described. A die having device structures formed thereon is provided. A thermal adhesive fills the surface of device structures formed on the die. The thermal adhesive is covered by a glass piece. A polishing step is performed to a non-device side of the die to form a thin sheet from the die. The glass piece is removed to expose the thermal adhesive. A sacrificial layer is then formed above the exposed thermal adhesive on the thin sheet. A slicing step is performed to form a TEM slide from the thin sheet.

The water penetration layer is a thin piece of non-woven fabric and is superimposed on the water absorption layer. The water absorption layer is made of a hydrophilic thin plate and is superimposed between the water penetration layer and the water-proof layer. The water-proof layer is made of a water-proof film material and is superimposed between the water absorption layer and the self-adhesive layer. The self-adhesive layer is made of a self-adhesive material and is superimposed below the water-proof layer.
