Title: Method of determining the coating thickness on the substrate
Inventor: HERTLING ROLF
IPC: G01B11/06
Filed: 1999-11-08
Granted: 2000-12-11
Abstract: This invention is about a kind of method for determining at least one coating thickness on the substrate, in which a simple and reliable measuring structure and more reliable measured results are generated. In the method, the relationships between zero order reflection and/or transmission value of light intensity and the wavelength are measured. In addition, the iteration model related to the parameters of each coating layer is used to calculate the reflection and/or transmission value of light intensity. The measured values are made to coincide with the calculated values by varying the coating layer parameters. Additionally, there is geometrical structure on the substrate and the geometrical sizes of the structure also become the extra parameters of the iteration model. According to the method of this invention, the geometrical sizes of the structure on the substrate can also be determined like the depth, the width, and the repetition interval of grooves in a blank for geometrical storage media, such as CDs.

Title: Angled printer cartridge
Inventor: BOLASH JOHN PHILIP
IPC: B41J2/515
Filed: 2000-01-25
Granted: 2002-02-21
Abstract: The specification describes a printer containing an angled printer cartridge and a method for printing using the cartridge. The printer is an ink jet printer which includes a print media movement device for moving a print media having through the printer along a print media path and a printer cartridge attached to the printer at an angle between 0 DEG and 90 DEG relative to an axis perpendicular to an axis along the direction of the media path through the printer. The printer cartridge has a length sufficient to print substantially the entire width of the printed width across the print media and contains a plurality of printheads along at least a portion of the length thereof, each printhead having one or more nozzle arrays. During a printing operation, only a portion of the printheads along the length of the cartridge are activated thus, reducing power consumption during printing. Angling the printer cartridge also has the advantage of increasing the print quality without increasing the density of nozzles in the nozzle array of the printhead.

Title: CATV tuner
Inventor: MATSUURA SYUUJI
IPC: H04N7/16
Filed: 2000-04-12
Granted: 2002-04-21
Abstract: A tuner has a receiving unit receiving a signal input from a CATV station to an HPF (1). In the receiving unit, the signal is attenuated by a PIN attenuator circuit (33) with the gain based on the signal level, thereafter the signal is amplified over a broad frequency range by a buffer amplifier (35), the high frequency component is amplified by a high frequency amplifier (32), and converted to a desired intermediate frequency signal by a frequency converting circuit including an oscillating circuit (7, 8, 13) and a mixing circuit (6, 28). Thereafter, the signal is IF-amplified by an IF amplifier (19) and output through a terminal (12). As the signal input to the amplifier (32, 35) succeeding the PIN attenuator circuit (33) is prevented from attaining a high level, signal distortion at the time of amplification can be improved, and supply current to the amplifier can be reduced.

Title: Hearing aid digital filter
Inventor: SJURSEN WALTER P
IPC: H04R25/00
Filed: 2000-05-30
Granted: 2002-03-11
Abstract: A digital hearing aid uses a digital filter using coefficient multipliers and with digital signal processing algorithms, which can be implemented with a minimum amount of dedicated circuitry, which may be contained in an integrated circuit. Power consumption in the digital hearing aid is kept to a minimum by the use of a single, general purpose multiplier by eliminating a multiplexed multiplier, and by eliminating a plurality of general purpose multipliers. Preferably, filter coefficients which are limited to powers of 2 are used in the digital filter, whereby coefficient multipliers function as shifters. Shifting-hardware is simpler and more economical compared to a multiplier. Multiplication by powers of 2 is implemented by circuit connections in the hearing aid circuitry, without requiring any power expenditure from the battery. The digital filter may be a non-recursive finite impulse response (FIR) digital filter, or, an infinite impulse response (IIR) digital filter.

Title: Process for expanded pellet production
Inventor: BHASKAR AJAY RAJESHWAR
IPC: A23L1/164
Filed: 2000-11-16
Granted: 2001-10-11
Abstract: In the process of producing masa based expandable pellets, preconditioner steam and water addition, as well as extruder water and RPM, can be manipulated to precisely control the cook level, gelatinization, and moisture level of the meal during processing, and level of defects despite minor variation in the characteristics of the masa flour. Specifically, the preconditioner added steam-to-water ratio can be manipulated to effect cook, hydration, and partial gelatinization of the meal. In the extruder, lower extruder rotational speeds increase the residence time and increases cook. With the increase in residence time the volume of bed pack in the extruder increases. This can be reversed by adding water directly into the extruder, thereby decreasing the viscosity of the meal in the extruder. Product bulk density is changed by increasing and decreasing cook of the meal.
