A method and apparatus, and variations of each, for inspecting a wafer defining at least one die thereon is disclosed. The present invention first obtains the electronic image equivalent of two die, and then determines the x and y offset between those electronic images. Prior to inspection for defects, those two electronic images are aligned by adjusting the x and y positions of one electronic image of one die with respect to the electronic image of the other die. Once that is accomplished, the those electronic images are compared to detect any defects that may exist on one of the die.

The present invention describes a internally geared display bicycle wheel covers that rotate upon a gear cluster in relation to the rotation of the bicycle wheel. The invention consists of twin disk assemblies mounted to both sides of a conventional bicycle wheel and inturn to the front and rear of a bicycle frame. The disk assemblies are manufactured of lightweight inexpensive material that is formed to the convex shape of the outer surface of a bicycle wheel and includes an internal gear mechanism made of a high density, self lubricating plastic. Gear ratios may be changed to achieve a desired rotation of the outer display disk or geared as such to hold the disk in an upright position at all times whether the bicycle is in motion or in repose.

A dark field inspection system that minimizes the speckle noise due to sample surface roughness can include a plurality of beam shaping paths for generating a composite, focused illumination line on a wafer. Each beam shaping path can illuminate the wafer at an oblique angle. The plurality of beam shaping paths can form a ring illumination. This ring illumination can reduce the speckle effect, thereby improving SNR. An objective lens can capture scattered light from the wafer and an imaging sensor can receive an output of the objective lens. Because the wafer illumination occurs at oblique angles, the objective lens can have a high NA, thereby improving optical resolution of the imaging sensor, and the resulting signal level.

A finger grip for a flangeless container, the finger grip having a skirt removably attachable to an open end portion of the container and a lip that extends radially outwardly from the skirt. The flangeless container is fillable by capping the container using a cap element to attach the finger grip to the container; installing the container in a container support assembly including a tray having a plurality of wells; filling the container; inserting a piston into the container; and removing the finger grip. Each well has a depth less than a predetermined length of the container, a lower portion of each well having a first cross-sectional shape similar to but greater than the cross-sectional shape of the flangeless container, an upper portion of each well having a second cross-sectional shape similar to but greater than the first cross-sectional shape.

The present invention relates to a medical container useful upon transportation of plural syringe barrels. The medical container includes at least a container main body and a holding member arranged inside the container main body. The holding member is provided at least with a plurality of cylindrical holding portions for holding syringe barrels. The container main body has at least a peripheral rim arranged on and along an outer periphery of an opening and a shoulder-shaped portion arranged on an inner wall of the container to arrange the holding member. The shoulder-shaped portion has at least three ribs for supporting the holding member, and has a structure that enables to arrange via the ribs the holding member in a horizontal position relative to a bottom wall of the container main body. According to the present invention, there is provided a medical container of a construction that can be promptly brought into a sterilized state by various methods, can be readily brought into a state capable of maintaining the sterilized state, and during transportation, can fixedly secure, without rattling, syringe barrels held upright by holders.

A semiconductor wafer inspection system and method is provided which uses a multiple element arrangement, such as an offset fly lens array. The preferred embodiment uses a laser to transmit light energy toward a beam expander, which expands the light energy to create an illumination field. An offset fly lens array converts light energy from the illumination field into an offset pattern of illumination spots. A lensing arrangement, including a first lens, a transmitter/reflector, an objective, and a Mag tube imparts light energy onto the specimen and passes the light energy toward a pinhole mask. The pinhole mask is mechanically aligned with the offset fly lens array. Light energy passing through each pinhole in the pinhole mask is directed toward a relay lens, which guides light energy onto a sensor. The offset fly lens array corresponds to the pinhole mask. The offset pattern of the offset fly lens array is chosen such that spots produced can be recombined into a continuous image, and the system utilizes a time delay and integration charge coupled device for rapid sensing along with an autofocus system that measures and cancels topological features of the specimen.

A vacuum packaging system for transporting a plurality of medical containers includes a plurality of medical containers each having a head side and a base side and a tray that receives and supports the medical containers. The tray includes opposing first and second sidewalls, opposing front and rear walls and a bottom floor. The walls extend generally vertically from the floor of the tray. At least one platform generally extends parallel to the floor of the tray. An air impervious flexible film defines an internal cavity. The air impervious flexible film completely surrounds the tray and the medical containers and the internal cavity is evacuated to and maintained at a predetermined vacuum level below atmospheric pressure. One of the head side and the base side of each medical container contacts a top surface of at least one platform when the medical containers are positioned in the tray.
