Abstract: A color image forming apparatus for printing color images for a plurality of recording mediums having one or more photoreceptors for forming toner images of different color toners. The toner images are superimposed onto the intermediate transfer drum having a length of circumference such that a plurality of color images for the plurality of recording mediums can be held on this intermediate transfer drum. The superimposition of colors is done by consecutively repeating the primary transfer of each toner developed on the photoreceptor to the intermediate transfer drum. The toner images are formed on the photoreceptor and transferred to the intermediate transfer drum consecutively if the color images to be printed are solely of a specific monochrome color.

Abstract: A circuit simulating the function of a diode in the sense that it conducts current in one direction and blocks current in the opposite direction, but which has a low forward voltage drop. A voltage comparator and a three terminal switch are connected so that the intrinsic reverse diode associated with the switch is harnessed to conduct current in the direction in which it is desired to conduct current and to block current in the direction in which it is desired to block current. A voltage comparator controls the control terminal of the three terminal switch to turn on the switch to conduct current and to interrupt current. Alternate embodiments of voltage comparators are disclosed. The voltage comparator may include charging and discharging transistors so that the switch turns on and off at a high speed. The invention further includes a method of conducting current in one direction and blocking current in a second direction which reduces power losses.

Abstract: Antenna elements 20 are arranged at intervals “d” greater than &lgr;/2, e.g., 5&lgr;. A signal received by an antenna element 20 is sent by way of an antenna multiplexer 21 to a receiver 23, where the signal is demodulated. The thus-demodulated signal is sent to a phase-and-power detection section 25, where a phase and power of the signal are detected. On the basis of the result of such detection, a control section 26 calculates the phase and power of a transmission signal. On the basis of the result of the calculation, a transmission signal generation circuit 27 transmits a transmission signal to each of the antenna elements 20 by way of the antenna multiplexer 21.

Abstract: The present invention relates to a spill resistant keyboard including at least one conduit to permit a spilled liquid to drain through the keyboard without damaging the keyboard's electronics. The conduit is positioned along a sloped surface located along a front edge of a recessed area of the keyboard to promote the drainage of the spilled liquid through the conduit. The keyboard also includes water protection walls positioned around certain elongated keys prevent the spilled liquid from entering the body of the keyboard.

Abstract: A method and a computer for execution of the method. As part of executing a stream of instructions, a series of memory loads is issued from a computer CPU to a bus, some directed to well-behaved memory and some directed to non-well-behaved devices in I/O space. Computer addresses are stored of instructions of the stream that issued memory loads to the non-well-behaved memory, the storage form of the recording allowing determination of whether the memory load was to well-behaved memory or not-well-behaved memory without resolution of any memory address stored in the recording.

Abstract: A semiconductor memory cell device exhibiting superior cell reliability comprising a dual layer floating gate wherein the thin upper layer of the floating gate overlaps the edges of surrounding field insulating regions and has rounded edges to minimize leakage concerns. The tunnel dielectric separating the dual layer floating gate from the substrate comprises a layer of uniform thickness which is grown prior to the formation of the field insulating regions. The Fowler-Nordheim tunneling mechanism is used for programming and erasing the inventive cells in a programming process flow which comprises flash programming all cells on a word line, sensing current on a selected cell, and selectively erasing the charge on the cell by applying a higher voltage on the intersecting bit line than is applied to the word line, until the sensed current is as desired.

Abstract: A delta-sigma D/A converter has a quantizer, a thermometer code converter portion, and an odd/even bit-interchanging portion. The quantizer produces a first digital signal. The thermometer code converter portion and odd/even bit-interchanging portion divide the output level of the first digital signal such that it is represented by the sum of the output levels of second and third digital signals. Each of the second and third digital signals has an output level obtained by dividing the output level of the first digital signal by a factor of 2 or an integer close to it. During the former half of each sampling interval, first and second adders produce, respectively, a level signal corresponding to the second digital signal and an inverted level signal corresponding to an inversion of the third digital signal.
