Patent EP-0630101-A2 (EP)
Inventor: POWELL JACK
IPC: H03F1/32
Filed: 1990-11-12
Abstract: In order to improve the distortion performance of a feed forward corrected amplifier an amplifier arrangement includes a distortion generator 312, intermediate the input 15 and the main amplifier 1. The arrangement is such that the input signal passes to the distortion generator 312 via a coupler 307. The signal passes via a delay network 310 which compensates for the delay of distortion network 312 and is tapped by a coupler 308 to be combined by a coupler 313 with the distorted signal from the distortion generator 312. In this way the output of the distortion generator is subtracted from a sample of the input signal so that only the distortion remains to pass via phase and amplitude correction networks respectively 314 and 315 to be amplified by a gain element 316 before being coupled back into the main signal path by a coupler 309. 
     The correction is active over a portion of the amplifier characteristic only,being the compression region of the amplifier Hence the amplifier compression point may be raised. Raising the compression point increases the overall power handling capability of the amplifier by increasing the level at which the overall arrangement will saturate to cause distortion.

Title: Imaging apparatus equipped with automatic recirculating document handler, and sheet-circulating feeder
Inventor: MATSUMOTO MANABU
IPC: G03G15/23
Filed: 1994-12-14
Abstract: Documents (D) stacked in a document tray (3) are fed from the lowermost sheet by a feeding belt (5) and then by a feeding belt (10) to a light exposure station (9) via feeding rollers (6, 8), and after light exposure are recirculated onto the uppermost sheet of the document tray (3) by a inverted feeding roller (13) via an ejection roller (11). When the documents (D) are double-sided, they are invertedly fed in the direction of a feeding path (19) by the feeding roller (8), fed to the light exposure station (9), and each side of the documents (D) presented for light exposure. Here, when trouble occurs in the copying unit, the document in the feeding path is returned to the document tray (3) while recirculative feeding of the documents remaining in the document tray (3) is performed for automatic restoration of the documents to their originally stacked state when returned to the tray. Therefore, only the minimum necessary number of documents are fed through the inverted feeding path (19). Thus, restoration of the initial stacked state of the documents may be carried out automatically for shortening of the time required therefor.

Filed: 1994-02-18
Abstract: A video decoder with a control unit (CC), a frame store (P) and a loop filter (F) for decoding coded video frames (q) block by block is described. The block-by-block decoding usually leads to artefacts during the reproduction of the decoded video frames on a monitor (M), which can be largely suppressed by filters following the decoder. An also extensive suppression of the artefacts with little circuit complexity is characterised by means  by which the control unit (CC) is enabled, in the decoding gaps,   - to read out predetermined pixel data of a decoded video frame from the frame buffer (P) and to supply these pixels to the loop filter (F) for filtering - to select the predetermined pixel data in such a manner that the filtering is carried out via the block edges of the blocks provided during the decoding.   The intended measures are compatible with a decoder according to Recommendation H.261. <IMAGE>

Abstract: A method, and associated apparatus, of measuring the mass M of a body located on a supporting platform to minimize the dynamical error during the settling time resulting when a measurement of mass is made within a predetermined time. The method includes subjecting the platform to a vibratory motion, measuring the change in period of vibration of the platform when the body is located on the platform to produce the direct measurement of mass M₁ of the body, measuring the weight of the body on the platform to produce the indirect measurement of mass M₂ of the body, and computing from these measurements the precise mass M of the body by combining the measurement M₁ and M₂ and assigning relative coefficients of proportionality to the measurement M₁ and M₂ such that a higher coefficient of proportionality is assigned to measurement M₁ at the beginning of the mass measurement time and a higher coefficient of proportionality is assigned to measurement M₂ at the end of the mass measurement time.

Abstract: Polyurethane-urea elastomers are made using as a chain extender 2-methyl-1,3-propanediol-bis-p-aminobenzoate which is the reduction product from hydrogenating 2-methyl-1,3-propanediol-bis-p-nitrobenzoate. The latter composition is preferably made by esterifying p-nitrobenzoic acid and 2-methyl-1,3-propanediol using a stoichiometric excess of the diol initially, adequate to render the reaction mixture processible, and after converting to a nonvolatile form sufficient diol to form diester with substantially all of the acid, removing free diol by distillation while continuing the esterification of unreacted acid and transesterification of monoester formed to diester. This process, which can be applied broadly to esterification of other nitroaromatic acids with other aliphatic diols, produces high yields of diester without needing extraneous solvent for processibility and with only water as a by-product. The 2-methyl-1,3-propanediol-bis-p-aminobenzoate exhibits reactivity and processing characteristics which make it a suitable drop-in replacement for MoCA in polyurethane-urea elastomer manufacture.

Abstract: A liquid crystal display apparatus and liquid crystal projection display apparatus, which employ a hologram color filter, and which are designed so that the illuminating light utilization efficiency is improved to a considerable extent, and that a color image can be faithfully displayed with excellent color reproducibility without uneven color or other similar problem. A color liquid crystal display apparatus (11) has a hologram (5), which diffractively disperses incident light so as to emanate light rays in different wavelength regions at a predetermined spatial period, as a color filter, and a liquid crystal display device (6). The display apparatus (11) is illuminated by white parallel back light (3) from an illuminator (14). A displayed image which is modulated in the color liquid crystal display apparatus (11) is passed through a field lens, which is disposed in the vicinity of the display apparatus (11), and formed as an enlarged image on a screen (19) for display through a projection lens (18). A short-wavelength cut-off filter whose transmittance for a wavelength not longer than 430 nm is not higher than 5% is disposed at a position in an optical path extending from a lamp (15) to the screen (19), thereby preventing crosstalk of colors which might otherwise occur when light which should be incident on a pixel assigned to display blue undesirably enters a pixel which is adjacent to the pixel for blue, and thus making it possible to display a faithful color image.

Abstract: In thermal inkjet printing, an energy source (20) supplies energy pulses to resistors (40) in a printhead. The number of energized resistors (40) changes from pulse to pulse as the printing proceeds. The changing number causes undesirable variations in the energy supplied to individual resistors (40), even when a regulated source is used, because of residual impedances in the source and wiring. The invention compensates for such energy variations, using information about the number of resistors (40) to be energized during a pulse. By referring to a predetermined relation between the number of resistors (40) energized and the power in each, the invention reduces or eliminates energy variations by an appropriate adjustment of the pulse with a pulse width modulator (26).
