Abstract: An electrophotographic device of the type including a flexible belt charge retentive member (10), driven along an endless path through a series of processing stations that create a latent image on the charge retentive surface, develop the image with toner, and bring a sheet of paper or other transfer member into intimate contact with the charge retentive surface at a transfer station (D) for electrostatic transfer of toner from the charge retentive surface to the sheet. For the enhancement of toner release from a surface at any of the processing stations, a resonator (152) suitable for generating vibratory energy is arranged in line contact with the back side of the charge retentive surface (10), to uniformly apply vibratory energy to the charge retentive member. The resonator comprises a horn (156), a continuous support member (154), and a continuous vibration producing member (150) that drives the horn at a resonant frequency to apply vibratory energy to the belt. The horn includes a platform or base portion (156), a horn portion (158) extending therefrom, and having a contacting tip (159). The horn is segmented, through the contacting tip to the platform portion, into a plurality of elements which each act more or less individually. In alternative embodiments, the vibration producing member that drives the horn, and/or the support member may also be segmented in a corresponding manner.

Abstract: The pixels of an image signal are converted into digital signals each corresponding to a density value. A maximum value and a minimum value, respectively, of the image signal densities of a particular pixel and one or more pixels around the particular pixel are detected, and the particular pixel is converted into a binary value using a threshold which is a median value between the maximum and minimum values detected. Respective characteristic quantities of a plurality of independent patterns which are separate from each other in a standard image are extracted. A relative coordinate system (X',Y'), based on respective position of center of gravity of two independent patterns 82, 83 which can be defined by different characteristic quantities is defined and, respective positions of centers of gravity of and respective characteristic quantities of the plurality of independent patterns in the relative coordinate system are registered. The independent patterns in an input image 81 are correlated with the independent patterns in a reference image (Fig. 7), and characteristic quantities of the corresponding patterns are compared to detect defects of the mark, if any.

Abstract: A receiver for receiving a stereophonic signal with upper and lower sidebands carrying a modulating signal includes independent sideband circuitry for providing upper and lower sideband signals. Selector circuitry responds to the level of audible noise in each of the upper and lower sideband signals for selecting that one of the sideband signals having a lower level of audible noise relative to the other. An ISB highpass filter filters the latter sideband signal to provide a highpass filtered sideband signal. Stereo detector circuitry provides left and right stereophonic audio signals. At least one audio lowpass filter filters the left and right stereophonic signals to provide corresponding lowpass filtered left and right stereophonic audio signals. At least one signal combiner combines the highpass filtered sideband signal with each of the lowpass filtered left and right stereophonic audio signals to provide corresponding composite left and right audio signals.

The semiconductor memory device further includes an additional function control circuit (229) for realizing a burst mode and a sleep mode. A data transfer path from DRAM to the SRAM and a data transfer path from the SRAM to the DRAM are separately provided in the bi-directional transfer gate circuit. Data writing paths (GIL) and (LIL) and data reading paths (LOL) and (GOL) are separately provided in the DRAM array. By the above described structure, operation of the buffer circuit is stopped in the sleep mode, reducing power consumption. Since data writing path and data reading path are separately provided in the DRAM array, addresses to the DRAM array can be applied in non-multiplexed manner, so that data can be transferred at high speed from the DRAM array to the SRAM array, enabling high speed operation even at a cache miss.

Abstract: The present invention is an isolation structure for use with FET or bipolar devices incorporating a silicon-germanium layer (20) in which the semiconductor devices are isolated by trench (15) structures. A trench is etched through a pad layer (40), a single crystal silicon layer (60), a silicon-germanium layer (20), and finally, into the silicon substrate. The silicon-germanium layer is interposed between the single crystal silicon layer and the silicon substrate and the pad layer covers the single crystal silicon layer. The trench sidewall (17) exposes the silicon-germanium layer. A single crystal silicon layer is formed as a trench liner. This silicon trench liner is then oxidized to passivate the trench isolation. The trench can then be filled with a dielectric without the devices being affected by parasitic leakage caused by the silicon-germanium layer exposed by the trench isolation.
