  • Publication number: 20220057693
    Abstract: This application provides a compact camera module, which includes a first actuator, an optical lens component, a ray adjustment component, and an image sensor. The ray adjustment component and the image sensor are sequentially disposed along a direction of a principal optical axis of the optical lens component. The optical lens component is configured to receive rays from a photographed object. The ray adjustment component is configured to fold an optical path of the rays propagated from the optical lens component. The first actuator is configured to drive the ray adjustment component to move, so that the rays whose optical path is folded are focused on the image sensor.

  • Patent number: 9074886
    Abstract: A line-width measurement device and a measurement method using the same are disclosed. The line-width measurement device has a platform, an image capturing device and a color-mixing light source device. The image capturing device captures an image of a pattern under measurement in a measurement area of the platform. The color-mixing light source device correspondingly provides illumination to the measurement area. The color-mixing light source device has a plurality of monochromatic light sources and adjusts the brightness scale of each monochromatic light source according to the matching rate of the pattern under measurement and a standard pattern to provide suitable color-mixed lights for illumination. Therefore, the present invention can provide a better measurement environment to further enhance accuracy of line-width measurement.

  • Patent number: 7078194
    Abstract: Mutant glycosidase enzymes are formed in which the normal nucleophilic amino acid within the active site has been changed to a nonnucleophilic amino acid. These enzymes cannot hydrolyze disaccharide products, but which can still form them. Using this enzyme, oligosaccharides are synthesized by preparing a mixture of an &agr;glycosyl fluoride and a glycoside acceptor molecule; enzymatically coupling the &agr.glycosyl fluoride to the glycoside acceptor molecule to form a glycosyl glycoside product using the mutant glycosidase enzyme; and recovering the glycosyl glycoside product. Particular enzymes include a mutant form of Agrobacterium &bgr.Glucosidase in which the normal glutamic acid residue at position 358 is replaced with an alanine residue.
