Title: Method and apparatus for correcting printhead, printhead corrected by this apparatus, and printing apparatus using this printhead
Inventor: HAYASAKI KIMIYUKI
IPC: B41J2/175
Filed: 1996-02-19
Abstract: An apparatus and method for correcting printing characteristics of a full-line printhead, and producing a high-printing quality printhead at high manufacturing yield, a corrected printhead by this apparatus, and a printer employing this printhead. According to this method, an image is printed on a printing medium by using double pulses obtained based on fluctuation of resistance of each printing unit of a printhead, and a reference OD value is determined from an OD value histogram of the printed image. A preheating pulse width is selected, based on OD values of n printed images obtained by changing the preheating pulse width n times and the reference OD value, such that an OD value on each printing element is equal or close to the reference OD value. For example, assuming that the reference value is 0.43, a preheating pulse width on printing element No. 3 is 0.875 µ sec.

IPC: C08F2/46
Filed: 1994-12-06
Abstract: This invention provides an improved coating composition for glass substrates that comprises a tetrasubstituted compound. The introduction of a tetrasubstituted compound in a coating composition for a glass substrate, and in particular an optical fiber, acts to delay the rate of deterioration of the glass or optical fiber due to moisture, and improves adhesion between the glass substrate and the coating composition. The introduction of a tetrasubstituted compound into a polymeric coating composition also improves the interlayer adhesion when more than one coating is applied to a glass substrate. This invention further relates to an outer primary coating composition or matrix material that comprises an acid functional ethylenically unsaturated monomer. This invention also provides an improved coated glass substrate having a decreased rate of deterioration due to moisture, improved adhesion between the glass substrate and the coating composition and between the various coatings, wherein the coating composition comprises a tetrasubstituted compound.

Title: High performance modem using pilote symbols for equalization and frame synchronization
Inventor: MARCHETTO ROBERT F
IPC: H04L27/34
Filed: 1995-03-17
Abstract: A modulator (fig. 2) that modulates and encodes data using data symbols (52), interspersed with pilot symbols (56), for transmission to another modem, and a demodulator (fig. 3) that decodes data symobls or a signal received from another modem. In the demodulator, a received signal is sampled at four times the symbol rate (104). The sampled signal is converted to quadrature signals and low-pass filtered to produce a complex baseband signal (120). Data symbols in the complex baseband signal are sampled (145) in synchronization with the start of each symbol based on the pilot symbols that are interspersed in the signal. By processing the pilot symbols, full modem synchronization is maintained down to a very low signal-to-noise ratio, through noise bursts, or even when the data symbols representing data are replaced by predefined sequences of data symbols that convey the dots and dashes of Morse code identifying the station transmitting the modulated signal. The continued presence of pilot symbols interspersed with the sequences of data symbols conveying Morse code prevents loss of synchronization between the transmitting station and the receiving station. the pilot symbols are also used to update equalizer tap coefficients in an equalizer (142) of the demodulator, thereby minimizing errors in the output data caused by channel fading, noise, and other effects. In addition, the sequence of pilot symbols is used to delimit data frames, so that bit synchronization and frame synchronization in the data are not required.

Title: Saturable bragg reflector structure and process for fabricating the same
Inventor: KNOX WAYNE HARVEY
IPC: H01S3/02
Filed: 1997-03-25
Abstract: Low optical loss and simplified fabrication are achieved by a nonlinear reflector which incorporates one or more semiconductor quantum wells within an n half-wavelengths strain relief layer (where n is an odd integer greater than zero) that is formed on a standard semiconductor quarter wave stack reflector. Growth of the half-wavelength layer is controlled so that dislocations are formed in sufficient concentration at the interface region to act effectively as non-radiative recombination sources. After saturation, these recombination sources remove carrier, in the quantum well before the next round trip of the optical pulse arrives in the laser cavity. The nonlinear reflector is suitable for laser modelocking at the high wavelengths associated with many currently contemplated telecommunications applications and provides, at such wavelengths, an intensity dependent response that permits it to be used for saturable absorption directly in a main oscillating cavity of a laser. Saturation intensity of the nonlinear reflector and thereby related laser modelocking properties can be controlled by disposing the quantum well(s) at a particular position within the strain relief layer.

Abstract: In order to prevent or minimize blocking artifacts from appearing in an image due to independent processing of each overlapped block of an image by one of many different filters, true pixel correction values are calculated, then added to each pixel of the image so that the transition between adjacent blocks of pixels will be smooth. This corrective method coined "stitching" is applied in either the spatial or the frequency domain to each block of filtered pixels in the image and generally includes the steps of: (i) choosing measurement points within a given block, so that the measurement points reside in areas overlapped by adjacent blocks and are situated in between pixels which have been saved (the saved region) and pixels which have been discarded during filtering; (ii) determining measurement point values at each measurement point by pixel measurement or approximation from neighboring pixels, as necessary; (iii) calculating measurement point correction values which will be non-zero when the measurement points are situated between pixels; (iv) calculating true pixel correction values for pixels situated in the saved region by interpolating between the measurement point correction values; and (v) modifying pixel values within the saved region in accordance with the true pixel correction values, respectively.
