摘要： A parking meter system consisting of a cylindrical housing having an upper section for a driver assistance display, control buttons, payment means and a time display. The housing is located adjacent a plurality of parking spaces and a single parking meter mechanism is mounted within the housing for controlling parking for each of the plurality of spaces. A separate enforcement display is located on the street side of the housing so that an enforcement officer can observe the compliance status without leaving his vehicle. The housing also supports a coin collection canister in a lower section thereof and access doors are provided for both the upper and lower housing sections for ease of servicing. The contours of the doors preserves the cylindrical housing shape when the doors are closed.

摘要： An electronic parking meter operating system comprising a microprocessor mounted within a meter housing, a semiconductor disc memory having at least 8K memory bytes, and a plurality of programs stored in the disc memory. A meter event such as the deposit of a coin will cause interrogation of an auxiliary program module map to determine if one of the plurality of programs should be used to substitute for or augment a program which is provided in the microprocessor to normally carry out meter functions. If substitution or augmentation is called for, an address table in the memory disc is used to locate the selected program, to load it into the microprocessor, and to execute the program.

摘要： Disclosed is apparatus, exemplarily semiconductor X-ray lithography apparatus, that comprises a novel projection system. In preferred embodiments the projection system is adapted for use with radiation of wavelength below about 30 nm. The system comprises four or more mirrors that form a finite conjugate "optical" system that is telecentric at the short conjugate. The mirrors can be selected such that an essentially flat, diffraction limited image is formed. The image field can be two-dimensional, exemplarily a 10.times.10 mm square, and the resolution over the image field can be higher than 0.25 .mu.m.Exemplarily, the "optical" system comprises, from long to short conjugate, a convex, a concave, a convex, and a concave mirror, with at least two of the mirrors being aspherics. The radius absolute values of the four mirrors are, in the above order and as a fraction of the system focal length, 2.20, 2.59, 2.51, and 2.13 all to within .+-.5%. Equivalently, the radii of the four mirrors are, in the same order, in the ratio of 1.00, 1.18, 1.14, and 0.97, all to within .+-.5%. The axial separations, in the same order and as a fraction of the system focal length, are 1.45, 1.47, 1.10, and 1.21, the last being the separation between the second concave mirror and the image, all within .+-.10%.
