20080280098 | Stretch Film - A stretch film comprising a base film made of a stretchable plastic film material, a multiplicity of holes in the base film arranged in several columns along a main direction, at least one reinforcement strip made of a stretchable plastic film material. The reinforcement strip is arranged and fixed on the base film in an area between two adjacent columns of holes. The thickness of the base film is greater than or equal to the thickness of the reinforcement strip and the width (w) of the reinforcement strip is as great as possible, but is such that the reinforcement strip does not contact or overlap the holes in the adjacent columns of holes. The reinforcement strip may be fixed to the base film so as to be inseparable and indistinguishable from the base film. | 11-13-2008 |
20090047468 | Packaging Film - A packaging film comprising a main film made of a stretchable polymer film material and having a multiplicity of holes on the main film includes is four conditions. A first condition means that a ratio of aeration percentage over final weight is greater than or equal to 14 meters per gram. The aeration percentage is calculated for a predetermined length of the packaging film as the total area covered by the holes over the total area of the packaging film including the area of the holes, when the packaging film is stretched to an elongation equal to the elongation at the Natural Draw Ratio point (NDR point). The final weight is the weight of the packaging film per film meter measured in grams per meter, when the packaging film is stretched at an elongation equal to the elongation at the NDR point. The second condition is that the width of the packaging film is reducible by less than 15% between a condition before any stretching of the packaging film and a condition when the packaging film is stretched at an elongation equal to the elongation at the NDR point. The third condition is that a ratio of an absolute value of the difference of a holding force of the packaging film minus a predetermined target holding force divided by the target holding force is less than or equal to 5%. The holding force of the packing film is determined as the tensile force at the NDR point. The force condition is that a ratio of an elongation at break of the packaging film measured along a transverse direction transverse to the main direction over the elongation at the NDR point is greater than or equal to 50%. | 02-19-2009 |

20120278957 | Scanning probe microscope with compact scanner - A scanner for a scanning probe microscope (SPM) including a head has a scanner body that houses an actuator, and a sensor that detects scanner movement. The scanner body is removable from the head by hand and without the use of tools and has a total volume of less than about five (5) square inches. Provisions are made for insuring that movement of a probe device coupled to the scanner is restricted to be substantially only in the intended direction. A fundamental resonance frequency for the scanner can be greater than 10 kHz. | 11-01-2012 |

20090032706 | Fast-Scanning SPM and Method of Operating Same - A method and apparatus are provided that have the capability of rapidly scanning a large sample of arbitrary characteristics under force control feedback so has to obtain a high resolution image. The method includes generating relative scanning movement between a probe of the SPM and a sample to scan the probe through a scan range of at least 4 microns at a rate of at least 30 lines/sec and controlling probe-sample interaction with a force control slew rate of at least 1 mm/sec. A preferred SPM capable of achieving these results has a force controller having a force control bandwidth of at least closed loop bandwidth of at least 10 kHz. | 02-05-2009 |
20130168929 | SEMICONDUCTOR WAFER ISOLATED TRANSFER CHUCK - A semiconductor wafer processing tool has a support structure for a coarse motion positioning system. A measurement head having a rigid super structure is supported from the support structure by vibration isolators and a top plate is mounted to the super structure. A vacuum transfer chuck is releasably carried by the coarse motion positioning system and releasably adherable to the top plate by application of vacuum. The vacuum transfer chuck supports a semiconductor wafer. | 07-04-2013 |
