摘要:
An optical aberration is intentionally introduced into the optical system which produces the scanning beam of an optical code scanner, in order to produce a scanning beam which has plural focal points or waists at different distances from the scanner. The operating range of the scanner can thereby be increased by taking advantage of different beam waist locations when the optical code is at different distances from the scanner. In accordance with an embodiment of the invention, coma is intentionally introduced to an optical system providing a light beam for an optical code scanner. This provides a scanning beam with plural beam waists at different distances from the scanner. This may be accomplished by orienting the light source and focusing optical system so that their optical axes intersect or by introducing an optical member, such as a prism, between the original light source and the focusing optical system.

摘要:
A compact barcode reader is provided in which the imaging lens and a linear sensor are in a straight line path with the barcode (no bend in path). By using a wide angle lens with a short back focus, it is possible to reduce the distance between the barcode and linear sensor to a fraction of what it was in the prior art. In addition, the maximum image height and the downward projection of the sensor are reduced to a fraction of what they were in the prior art. As a result, despite the straight line optical path, compact barcode reader becomes so small that it does not interfere with the operation of the beverage maker.

摘要:
The present invention is for efficiently managing large numbers of apparatuses using multiple management protocols. A management information acquisition part 1A uses multiple different management protocols P1 and P2 to acquire management information for each of the management protocols from each apparatus 3. Anode configuration information management part 1B identifies apparatus configuration information acquired from the same apparatus of the respective apparatuses 3 by comparing the apparatus configuration information, and collectively manages these multiple pieces of apparatus configuration information as a single piece of apparatus configuration information. A component information management part 1C identifies multiple pieces of component information related to the same component, and manages these identified multiple pieces of component information after associating these pieces information with each other.
摘要:
A changeable apparatus for scanning a symbol is disclosed wherein by selectively changing the position of a bending mirror (101), different scan patterns are produced. In a preferred embodiment, the different positions of the bending mirror (101) result in a scanning beam (107, 108) being directed off of different polygon scanning mirrors (104, 105) to create the different scanning patterns.

摘要:
A silicon annealed wafer having a sufficient thick layer free from COP defects on the surface, and a sufficient uniform BMD density in the inside can be produced by annealing either a base material wafer having nitrogen at a concentration of less than 1×1014 atoms/cm3, COP defects having a size of 0.1 μm or less in the highest frequency of occurrence and no COP defects having a size of 0.2 μm or more, oxygen precipitates at a density of 1×104 counts/cm2 or more, and BMDs (oxygen precipitates), where the ratio of the maximum to the minimum of the BMD density in the radial direction of the wafer is 3 or less, or a base material wafer grown at specific average temperature gradients within specific temperature ranges and specific cooling times for a single crystal at a nitrogen concentration of less than 1×1014 atoms/cm3, employing the Czochralski method. Moreover, a silicon epitaxial wafer having very small defects and a uniform BMD distribution in the inside can be formed by growing an epitaxial layer on the surface of either the first type base material wafer or the second type base material wafer. Both the silicon annealed wafer and the silicon epitaxial wafer greatly reduce the rate of producing defective devices, thereby enabling the device productivity to be enhanced.

A handheld imaging device includes a CCD array or similar detector which is tilted with respect to the incoming light. The tilt permits a narrower handheld device to be manufactured, as the housing need not be as wide as the CCD or similar array.
