    摘要： A computer system and method provide a CAD tool by which application specific optical integrated circuits may be easily and quickly designed. The computer system has a graphical user interface which provides the designer with an empty canvas upon which the user may place selected icons of any one of a plurality of optical devices. The designer can select from any one of a number of interconnects to place an icon of the selected interconnect between two of the optical devices. The characteristics of each optical device or interconnect may be varied from default settings to a desired group of settings. To verify the operation of a designed circuit, the user simply clicks each icon along an optical path and the computer system provides a spectral analysis of optical power versus wavelength for the defied optical path. The user can also design optical chips by selecting and placing end ports into an optical circuit and can then clump or group the entire optical circuit into a single icon representing the chip. The computer system also provides the designer with the ability to group optical chips together to form wafers. The optical circuits, as well as the chips and wafers, may be designed in any one of several manufacturing standards.

    摘要： Process for the preparation of chlorite salts by the controlled reaction of chlorine dioxide with a reducing agent under reduced pressure to form chlorous acid. The chlorous acid is reacted with an aqueous solution of base to form the desired chlorite salt. The process is rapid, economical and is conducted in a generator which is significantly smaller than equipment currently used for production of chlorite salts.

    摘要： Process for the preparation of saturated aqueous solution of chlorite salts by the controlled reaction of chlorine dioxide with a reducing agent under reduced pressure to form chlorous acid. The chlorous acid is reacted with an aqueous solution of base to form an aqueous solution chlorite salt and the aqueous solution is recycled through the process. The process is rapid, economical and is conducted in a generator which is significantly smaller than equipment currently used for production of chlorite salts.

    摘要： A ballast circuit system provides for efficient starting and operation of high voltage discharge lamps using a common 120 volt AC power source. As a result of this improved ballast circuit system, the necessary high voltage is generated from a normal 120 volt AC in such a way that there is low power loss. The system efficiency allows for use of plastic fixtures and small size packaging of the discharge lamp.
