摘要： An optical system for an automatic lens meter for measuring the refractive power of a lens to be examined. The optical system includes a light source for generating a measuring light beam, a convex collimator lens, disposed a predetermined focal distance from the light source, for collimating the measuring light beam, so that the light beam move in parallel, an expanding concave lens, disposed downstream of a lens to be examined, for expanding the measuring light beam with respect to an optic axis, a plural-apertures stop, disposed downstream of the expanding concave lens and formed with a plurality of apertures along the circumference thereof at predetermined angular intervals, for separating the measuring light beam into a plurality of measuring light beams, a prism lens in which a convex lens and a fixed prism assembly are integrally formed, disposed directly downstream of the plural-apertures stop, having the convex lens to focus the plural measuring light beams passed through the plural-apertures stop, and the same number of prisms as the number of the plural apertures to deflect the focused light beams so as to maintain the light beams in the separated beams, and an image forming lens, disposed downstream of the prism lens, for forming aperture images of the measuring light beams, passed through the prism lens, on a two-dimensional sensor array.

摘要： A hierarchical word line driving circuit for a semiconductor memory device can reduce a sub-threshold voltage leakage current because a sub-word line is disabled at a back bias voltage, overcome a layout penalty because an additional NMOS transistor for preventing the sub-word line from floating is not employed, and sufficiently obtain a line pitch passing above the sub-word line. The hierarchical word line driving circuit for the semiconductor memory device includes: a main word line driver including a transmission gate for selectively outputting a main word line signal, a selective latch unit for selectively latching and outputting the main word line signal selectively transmitted by the transmission gate, and a level shift unit for outputting an output from the selective latch unit or a back bias voltage according to a block selection signal and the main word line signal; and a sub-word line driver controlled according to an output from the main word line driver, for driving a sub-word line by using an inputted lower coding signal or a ground voltage.

摘要： A semiconductor memory device employs an adaptive output driver to vary the strength of the output driver with the variation in external voltage and temperature. For this purpose, the semiconductor memory device with the adaptive output driver includes a shift register unit for producing a control signal so as to control the voltage level of the adaptive output driver, a data masking buffer for generating a reference voltage to be compared with the voltage level of the adaptive output driver, an adaptive output driver for varying its strength in response to the control signal provided from the shift register unit, and a comparator for comparing the reference voltage with the voltage level of the adaptive output driver to thereby generate a signal determining whether or not the shift register unit should perform a shift operation.
