Abstract:
An optical assembly with having a dust seal incorporated therein is disclosed. The optical assembly has a first portion and a second portion separated by a space wherein at least one optical component is located in the space. The dust seal may be a section of polyolefin tubing or heat shrink tubing that encompasses the space. The dust seal is placed adjacent a section of the first portion and a section of the second portion. Heat is then applied to the dust seal, which causes it to shrink and, thus, conform to the first portion and the second portion. The conforming dust seal seals the optical assembly and prevents contaminants from interfering with the optical components located in the space.
Abstract:
A four-direction adjustable optical module including a carriage and a CCD module is disclosed. The carriage includes a coupling window for coupling with the CCD module. Each of the two sides of the CCD module includes a screw hole and an elastic device. The elastic device slightly protrudes from the surface of the coupling window. While the CCD module and the coupling window are coupled, screws are employed to screw through the CCD module and into the screw holes of the coupling windows. Therefore, the elastic devices deform by the stress from the CCD module. By adjusting the tightness of the screws, the orientation of the CCD module rotating on the Z axis can be calibrated. Thus, the adjustable optical module of the invention can be calibrated at least in four directions.
Abstract:
A scanner head cartridge is constituted by a lower case which houses optical parts required for reading and electrical parts required for image processing, and an upper case which can engage with the lower case to cover the open surface of the lower case, and a positioning guide means used upon inserting the cartridge into the carriage is formed on the surface of the upper case, that is opposite to the lower case. A scanner head cartridge is held on a carriage that moves an ink head cartridge of an ink-jet printer for performing recording on a recording medium, in place of the ink head cartridge, and can be commonly used using a common base unit even in carriages which mount different ink head cartridges and have different shapes. In addition, the scanner head cartridge allows easy adjustment of the optical system.
Abstract:
A specimen block storage module containing a plurality of shaped cavities into which each of a plurality of specimen blocks “snap”, i.e., are mechanically held in place by structural projections or detents formed on the cavity walls, thus eliminating the possibility of inadvertent dislodgement. Each cavity is indexed, e.g., by letter and number, providing for the rapid, accurate identification of every individual block. Each of the modules has on its undersurface a pressure sensitive adhesive which permits the module to be attached to any appropriate surface; e.g., the inside bottom of a fitted box, or in any combination desired onto a specially-designed, suitably-sized and preferably covered panel that fits into a protective binder (e.g., a standard three-ring binder) for holding a plurality of the panels in the desired order. Many such panels can be stored in a single binder, separated by indexed dividers on which data can be recorded, and, as a consequence of the “snap-in” feature, the binders can be stored in an upright position without the blocks becoming dislodged.
Abstract:
A SMIF box cover hold down latch and box door latch actuating mechanism installed in the port door of a SMIF system has two box door latch actuating pins extending from a central pivot shaft of the actuating mechanism to mate with corresponding holes in the cam component of the box door latch mechanism. In a preferred embodiment the central pivot shaft moves about a central pivot axis between first and second predetermined angular positions. Movement to the first angular position imparts linear movement of trucks attached to first and second rod members and causes push pins to retract from their corresponding box cover hold down latches to secure the box cover to the port plate and imparts angular movement to the two actuating pins and causes them to operate the box door latch mechanism to release the box door from the box cover. Movement to the second angular position imparts linear movement to trucks attached to first and second rod members and causes push pins to extend toward and contact their corresponding box cover hold down latches to release the box cover from the port plate and imparts angular movement to the two actuating pins and causes them to operate the box door latch mechanism to secure the box door to the box cover. Multiple wafer registration detector subassemblies ensure that semiconductor wafers stored in a cassette holder contained within the SMIF box are properly registered before an elevator assembly moves the cassette holder beneath a SMIF system processing station canopy.

The system includes electrodes connecting the sensor to an output device.
Abstract:
In order to locate a package (110) which houses active elements including an opto-electric type transducer (100), in a position which assures that the opto-electric sensor and other active elements will be located in proper operative positions when the package is installed in predetermined piece of apparatus, the package casing (102) is provided with location features (112) at least some of which are deformable. During optimization, the package is moved with respect to a target until such time as the sensor is detected as producing an optimal output. Selected location features are then deformed to form location faces (112a) which have a predetermined spatial relationship with the active elements and which ensure that the active elements will be supported in an optimally operative position when the package is operatively disposed in a device such as an optical scanner or the like.
Abstract:
A system and method for focusing infrared detectors operable at cryogenic temperatures. The invention includes a sensor (10) for detecting electromagnetic energy comprising a first detector (14) operable over a first temperature range and a predetermined number of auxiliary detectors (12) operable over a second temperature range, wherein the auxiliary detectors (12) are adjacent to and in the same optical plane as the first detector (14). In the illustrative embodiment, the energy is infrared or visible light, the first temperature range is a range of cryogenic temperatures, and the second temperature range is a range of ambient temperatures. The first detector (14) is a focal plane array and the auxiliary detectors (12) are uncooled detector arrays. In the preferred embodiment, the focal plane array (14) and the uncooled detectors (12) are disposed on a common substrate. In accordance with the teachings of the present invention, the novel sensor (10) can be used to focus an optical system at cryogenic temperatures. The inventive method includes illuminating energy onto the sensor (10) through the optical system at ambient temperatures and then adjusting the position of the sensor (10) until maximum illumination is received by the auxiliary detectors (12). This determines the location of the focal plane of the system at ambient temperatures. The location of the focal plane at cryogenic temperatures can then be calculated using the location of the focal plane at ambient and a model of the thermal characteristics of the system.
