Patent EP-0590600-A2 (EP)
Inventor: GRANGER EDWARD M C O EASTMAN K
IPC: H04N1/405
Filed: 1993-09-28
Abstract: A technique, including apparatus and accompanying methods, for use in a tile oriented digital screener for suppressing screener induced image artifacts through use of "blue noise" based selection among a number of different halftone dot fonts. Specifically, in producing a screened halftone dot pattern for any density value, a two-dimensional seamless matrix of blue noise correlated uniformly distributed integer values is used to select one of a number of different halftone dot fonts that will be produced for any halftone density value. The amount of blue noise in the matrix is specifically tailored, both in amplitude and frequency response, to substantially suppress all low frequency image artifacts and place resulting screening errors at sufficiently high spatial frequencies so as to render these errors essentially invisible to a human observer. Across identical density values, these fonts illustratively contain symmetric edge variations, and substantially constant dot area and dot center locations. Through use of this technique, any noticeable increase in image granularity is also advantageously avoided.

Abstract: The invention relates to a breathable, plastic film, useful as a wall covering material. A low boiling additive, such as water, is added to a plastisol before extrusion. During extrusion and curing of the plastisol into a film or coating, the low boiling additive is volatilized and the resulting evolved gas perforates the forming film. In this manner a permeable plastic film, such as vinyl, is produced.

Abstract: An apparatus and method for processing the input digital signal is disclosed. An input digital audio signal at an input terminal 11 is supplied via a one-block delay unit 17 to a difference unit 20, an output of which is processed by an annexed noise-shaping circuit 21 and restored by a near-instantaneous compressor 26, a near-instantaneous expander 27 and an accumulator 28 so as to be fed back to the difference unit 20 to find a difference between a signal of a directly preceding sample and a signal of the current sample. The annexed noise shaping circuit 21 modifies the spectrum of the quantization noise by taking aural characteristics, such as equal-loudness characteristics or masking characteristics, into account for diminishing the level of the quantization noise as perceived by the ear. The noise level as perceived may be reduced in a manner desirable for the sound quality without changing the existing format.

Abstract: A radio selective calling receiver including an exchangeable first battery and a second battery which can be charged by the first battery. A CPU stops operating at a stop voltage. A RAM stores a user data. A stop detector detects operational stop of the CPU. A power supply changer changes one of the first and second batteries into the other and selectively supplies one of electric energies of the batteries to the CPU, RAM and stop detector. The minimum operable voltages of the RAM and the stop detector are lower than the stop voltage. The first battery supplies its electric energy to the CPU, RAM and stop detector until the supply voltage of the first battery lowers to the stop voltage. The power supply changer changes the first battery into the second battery when the operational stop of the CPU is detected, so that the second battery supplies its electric energy to the CPU, RAM and stop detector until the first battery thus lowered in supply voltage is exchanged by a new one. The capacity of the first battery can be effectively used without any malfunction of the receiver and no troublesome reinput action is required for the user.

Abstract: An image-quality stabilizer provided in a copying machine executes a feedback control on a charger (2) output based on an adhering toner amount detected by a patch sensor (9) in a pre-rotation of the photoreceptor drum directly before each copying operation is started. A time interval between feedback controls is counted by a timer (15), and CPU (14) sets a time interval in accordance with an amount of change in adhering toner amount obtained based on the detected adhering toner amount is set in the timer (15). According to the described arrangement, since the feedback control is executed at a timing set in accordance with the amount of change in adhering toner, variations in image quality such as an increase in image density caused by overcompensation and an excessive feedback control can be prevented, thereby ensuring stable image quality by efficiently compensating the image density without increasing an amount of toner consumption.

Abstract: A processing time is reduced without using expensive hardware. A head reads images of originals which are contained in an i-th original photo film Fi all at one time as it moves in a subscanning direction and as an original drum rotates in a main scanning direction. At this stage, a switch connects the head to a first band memory and a switch connects a second band memory to an image processing circuit. During the reading of the images, image signals are stored in memory sectors of the first band memory original by original while image signals regarding an (i-1)-th original photo film (F(i-1)) are serially read, processed and stored in a magnetic disk original by original. When the head read images of an original photo film (F(i+1)) all at one time, the switches are switched each other so that writing in the second band memory and reading from the first band memory are performed simultaneously.

Two out of phase (by π/2) sine wave signals are derived (by 101,102) from the input sine wave (on 105), and these two out of phase signals are squared (in 115,117) and summed (in 119) to derive or estimate the desired square of the sine waveform signal at a fast response time while substantially excluding ripple of the estimated out of phase sine waves. An estimating circuit, described herein, comprises two integrator circuits (101,102) series connected into a substantially closed loop. The output of the second integrator (102) circuit is fed back to the input of the first integrator circuit (101). The output of each individual integrator circuit is a voltage sine wave separated in phase from the output of the other integrator by π/2 and in synchronism with the input substantially sine wave voltage V AC . The output of each of the integrator circuits is squared in an associated squaring circuit (115,117).

Abstract: The present invention includes plural plasma etching vessels and a wafer queuing station arrayed with a wafer transfer arm in a controlled environment. Wafers are movable within the controlled environment one at a time selectably between the several plasma vessels and the wafer queuing station without atmospheric or other exposure to that possible contamination of the moved wafers is prevented. The system is selectively operative in either single-step or multiple-step processing modes, and in either of the modes, the several plasma etching vessels are operable to provide a desirably high system throughput. In the preferred embodiment, the several plasma vessels and the queuing station are arrayed about a closed pentagonal locus with the wafer transfer arm disposed within the closed locus. The wafer transfer arm is movable in R and TT between the several plasma etching vessels and the wafer queuing station, and selectably actuable vacuum locks are provided between each of the plasma etching vessels and the R and TT movable wafer transfer arm to both maintain an intended atmospheric condition and to allow wafer transport therethrough. The plasma vessels each include first and second water-cooled electrodes that are movable relatively to each other so as to provide a selectable gap dimension therebetween. One of the electrodes includes a selectively movable pedestal portion slidably mounted thereto that is cooperative with the R and TT movable wafer transfer arm to load and unload wafers respectively into and out of the associated plasma vessel. The wafer transfer arm is operative to pick-up the wafers by back-side and peripheral wafer contact only, which therewith prevents possible front-side contact-induced contamination of the wafer surfaces. A sensor on the transfer arm is operative to provide a signal indication of proper wafer seating. 
     Wafer processing in each vessel is regulated by a state controller for processing a plurality of wafers from a single cassette, contained within the vacuum environment of the plural plasma etching vessels and wafer queuing station, to provide an orderly and efficient throughput of wafers for diverse or similar processing in the plural vessels. In this manner a wafer can be processed as soon as a vessel becomes available.
