Abstract: A fundamental limit to the sensitivity of optical interferometry is thermal noise that drives fluctuations in the positions of the surfaces of the interferometer's mirrors, and thereby in the phase of the intracavity field. A scheme for substantially reducing this thermally driven phase noise is provided in which the strain-induced phase shift from a mirror's optical coating cancels that due to the concomitant motion of the substrate's surface. As such, although the position of the physical surface may fluctuate, the optical phase upon reflection can be largely insensitive to this motion.

Abstract: A display pack for a consumer product is made of two sheets of corrugated cardboard and a clear plastic container with a flat insertion portion sandwiched between the cardboard sheets. The two cardboard sheets are adhered together in a peripheral area of the package by a heat-sensitive adhesive, and the corrugations of the cardboard sheets are crushed and flattened in the peripheral area. To seal the package, the peripheral area of the two cardboard sheets is subject to sufficient pressure to crush the corrugations inside the cardboard sheets and flatten them in that area. Heat is applied to the outer side of the cardboard sheets in the peripheral area and conducted to the adhesive material between the two sheets to activate the adhesive material. A sealer machine with a heated sealing press or parallel sets of heated rollers may be used to carry out the sealing process.

Abstract: A wafer grinding machine and a wafer grinding method are disclosed. A barrier (60) is arranged around a holding unit (29) to hold at least a wafer (40) with a film (11) attached on the front surface (41) thereof and with the back surface (42) thereof directed upward. The upper surface (61) of the barrier unit is ground to the position between the back surface of the wafer held by the holding unit and the boundary between the wafer and the film. Then, the wafer is ground while being held with the back surface thereof up by the holding unit. As a result, the film is prevented from coming off from the wafer at the time of grinding the back surface of the wafer. Further, when the wafer is ground, a fluid may be supplied into the gap between the barrier unit and the outer peripheral portion of the wafer held by the holding unit.
