摘要:
A stack package of the present invention is made by stacking at least two area array type chip scale packages. Each chip scale package of an adjacent pair of chip scale packages is attached to the other in a manner that the ball land pads of the upper stacked chip scale package face in the opposite direction to those of the lower stacked chip scale package, and the circuit patterns of the upper stacked chip scale package are electrically connected to the those of the lower stacked chip scale package by, for example, connecting boards. Therefore, it is possible to stack not only fan-out type chip scale packages, but to also efficiently stack ordinary area array type chip scale packages.

A liquid crystal display having a plurality of gate lines and a plurality of data lines extending in row and column directions, respectively, are formed on a panel. A switching device connected to the gate line and the data line and a pixel electrode connected thereto are provided in each of pixel areas partitioned by the gate lines and data lines. A data driving circuit and a data driving circuit are also provided on the panel, and apply voltages to the gate lines. A signal wire connected to the data driving circuit and including a plurality of color signal lines is provided on the panel and connects the data driving circuit to a signal controller of a printed circuit board. A pair of the plurality of color signal lines with differential relationship transmit color signals to the data driving circuit. A distance between the pair of the plurality of color signal lines is smaller than a width of each of the pair of the plurality of color signal lines and a distance between a pair of plurality of color signal lines without differential relationship. This relationship of the distances between the signal lines and the width thereof reduces the EMI noise.

A computer system capable of providing a visual display of a display power management signaling (DPMS) mode for user selection of different power save modes of operation. The DPMS mode is used to convert a power supply mode to a power save mode in a computer peripheral such as a monitor. The computer system includes a micro-computer installed in the monitor for determining whether the frequency of sync signals are within predetermined bands to set the power save mode, a switching element installed in the computer for controlling the power supply of a predetermined voltage under control of the micro-computer, and a luminance element installed at a predetermined location of a keyboard and powered by the operation of the switching element for providing a visual display of the DPMS mode for user selection of different power save modes of operation.

An apparatus for measuring the linewidth of a laser is disclosed in which the linewidth of a laser is measured in a wide range from a narrow linewidth to a wide linewidth by utilizing frequency-shifted rays based on a stimulated Brillouin scattering within an optical fiber in an easy and efficient manner. The apparatus according to the present invention includes: an optical signal generating and splitting means for generating optical signals under test, and for splitting them into two sets of signals; a frequency shifting means for amplifying the optical frequency of the optical source of the optical signal generating and splitting means, and then, irradiating the amplified signals into an optical fiber so as to shift the frequency based on a stimulated Brillouin phenomenon; a leading means for minimizing a loss of the frequency shifted rays outputted in a direction opposite to that of original laser beams of the frequency shifting means so as to leading them in a certain direction; and a spectrum analyzing means for receiving the original rays from the optical signal generating and splitting means and for receiving the frequency-shifted rays from the leading means so as to stimulate beatings and to analyze the beaten spectra. The apparatus is applied to measuring the linewidth and channel interval of a laser used in wavelength division multiplexing optical communications.

摘要:
An electrophotographic process cartridge develops an electrostatic latent image with two layers or less of polymeric toner. The electrophotographic process cartridge includes a charging roller for uniformly distributing a layer of electrical charge on an outer surface of a photosensitive drum, a developing roller for transferring particles of polymeric toner each having a substantially spherical shape onto the outer surface of the photosensitive drum, and a control roller for engaging an outer surface of the developing roller to enable formation of two layers or less of polymeric toner particles on the outer surface of the developing roller. The particles of polymeric toner are transferred from the outer surface of the developing roller to the outer surface of the photosensitive drum for a printing operation, and remaining toner particles are transferred from the outer surface of the photosensitive drum back to the outer surface of the developing roller after the printing operation by a bias voltage applied to the developing roller.
