Abstract: Provided an optical system having a multiple curvature lens and a method for manufacturing the same. The optical system includes an image-forming lens group, an image sensor, and an image processing unit. The image-forming lens group has one or more multiple curvature lenses each having a multiple curvature surface provided on at least one refractive surface on one side of the multiple curvature lens. The multiple curvature surface includes two or more curved surfaces of different curvatures formed in a concentric circle. The image-forming lens group also has one or more single curvature lenses arranged before or after the multiple curvature lens and having a refractive surface. The refractive surface includes a continuous curved surface of a single curvature radius formed on both sides of the single curvature lens. The image sensor senses an image formed by the image-forming lens group, and the image processing unit recovers the image sensed by the image sensor.

Abstract: Provided are an optical system for processing an image using a PSF and an image processing method thereof. The optical system includes one or more lenses, an image sensor, and an image processor. The image sensor senses an image formed by the lenses, and the image processor recovers the image sensed by the image sensor using a PSF. A BFL defined as a distance between a refractive surface of one of the lenses that is closest to an image-side and the image sensor, is controlled such that ?PSF defined by Equation below has a value less than 100%. ? ? ? ? PSF ? ( % ) = PSF ? - PSF macro ( PSF ? + PSF macro ) / 2 × 100 An image is recovered using a PSF, so that an excellent image can be obtained over a wide object distance range.

Abstract: Distributed valve simulated moving beds are described in which junctions located between successive columns interrupt the flow of process fluid between columns, and either transmit the process fluid through a zone bypass to a succeeding column within the same zone or, if the junction is located between zones, direct the process fluid to an input/output line that is dedicated to the particular zone that immediately follows the junction. At each step of the SMB's operation, the distribution of flows in each junction is modulated to accomplish movement of ports consistent with the SMB's design. The described system can be employed to accomplish moving ports chromatography. Further described are simulated moving beds that contain one or more decoupled on-line regeneration zones. The regeneration zone is decoupled from the separation zones in the sense that it observes a step time (a “regeneration interval”) that is different than the step time observed by the separation zones of the SMB.

Abstract: A desktop support for LCD mainly consists of a fixture module and an inclined support module. The fixture module is composed of two axles directly molded from the back of LCD and two sleeves on top of the base. The inclined support module consists of a rotary frame on the bottom back of LCD and a set of adjustable fixture at base bottom, against which the frame rod sits by gravity. Through this, the two axles of the fixture module are placed in the sleeves. Thus, LCD sits vertically against one side of the base by gravity and rotation. The frame rod can match the adjustable fixture to adjust the LCD angle. The axle, the frame and the adjustable fixture form a triangle support. After angle adjustment, LCD can still stand up firmly.

Abstract: A computer mainframe and display arrangement is constructed to include a mainframe for personal computer, the mainframe having a locating slot in one recessed side panel thereof, and a display fastened pivotally with the mainframe, the display having a locating block fixedly provided at a back sidewall thereof, a coupling plate fastened pivotally with the locating block and forced into engagement with the locating slot of the mainframe to pivotally secure the display to the mainframe, and a foldaway stand pivoted to the locating block and adapted to support the display on the mainframe in a tilted position.

Abstract: A computer and wheeled carrier combination structure includes a wheeled carrier, the wheeled carrier having a wheel holder frame supported in between a base and a top cover plate thereof and a plurality of wheels respectively pivoted to protruded ends of the wheel holder frame outside the base for moving the wheeled carrier on the floor, a retractable upright vertically fastened to the wheeled carrier, a display module and an operation platform angularly adjustably pivoted to the upright at different elevations, the operation platform having a top keyboard hole holding a keyboard in flush with the top side of the operation platform.

Abstract: A CD-ROM rack includes a rack body adapted to support computer readable disk drivers/players on the inside at different elevations, the rack body having transverse sliding tracks at two opposite side panels thereof, a plurality of retaining spring plates respectively riveted to the side panels of the rack body and adapted for locking loaded computer readable disk drivers/players, and a plurality of elongated holding down plates respectively inserted into the transverse sliding tracks to hold down the retaining spring plates in the locking position.

Abstract: A fan and hood arrangement includes a mounting shell fastened to the inside of a computer mainframe shell to hold a fan, and a hood pivoted to the mounting shell by a slip joint and fixed thereto by a lock screw, the fan having a mounting flange engaged into a gap between a partition board and stop blocks in the mounting shell, the mounting shell having inside spring plates, each spring plate having a retaining rod forced into engagement with a respective locating hole in the mounting flange of the fan.

Abstract: A process for the management of by-product tetranitromethane (TNM) which avoids the hazards of the prior art isolation or extraction procedures. A selected in-plant liquid or vapor stream, or a reactor off-gas stream from nitration or nitric acid oxidation plant, which contains TNM, is heated to effectively pyrolyze the TNM without undue losses of nitric acid values.

Abstract: A process and apparatus is provided for the continuous manufacture of a water-in-oil explosive emulsion precursor. Separate streams of the water phase component and the oil phase component are introduced into an in-line motionless mixer. A chosen portion of the output from the mixer is recirculated and returned to the motionless mixer for further emulsification. The process allows for the production of a very high phase ratio water-to-oil emulsion (up to 95% water phase) without phase inversion after long storage. The precursor is simply converted to a sensitive explosive by means of known density lowering techniques.
