Abstract: An air-driven rotating window assembly (10) mountable to one side of a viewing window (16). The rotating window (12) assembly faces toward the working or weather exposed area and slings off, by centrifugal force, any debris that contacts the rotating window (12) so as to maintain clear visibility through a portion of the viewing window over which the rotating window extends. The rotating window assembly (12) includes a support base (14) and a rotating window rotatably mounted to the support base. The rotating window has an annular frame (17) with propulsion passages (19) therein that receive a flow of pressurized gas substantially tangentially to the frame. The propulsion passages redirect the gas to generate a propulsive force on the frame to spin the rotating window relative to the support base. The gas exits the annular frame (17) through a restricted gap between the support base and the rotating window so as to form an air barrier that prevents debris from passing through the gap. <IMAGE>

Abstract: Method and apparatus for coating catalytic converter substrates with an exact amount of a precious metal. In the course of operation of the apparatus, a hollow substrate to be treated having opposed open ends is transferred from a starting location such that one end is lowered into a dip pan into which has been introduced a predetermined amount of slurry material containing the precious metal. With the one end immersed in the slurry, a vacuum placed on the other end of the substrate draws up the entire charge of slurry from the dip pan to coat the lower portion of the substrate. Thereafter, the substrate is raised from the dip pan. The vacuum continues to operate to cause the coating to be evenly distributed on all the interior surfaces of the substrate. Then the substrate is rotated and again lowered so that the other end is immersed in another predetermined charge of the slurry and the process is repeated. Thereupon, the substrate is again raised from the dip pan. Again, the vacuum continues to operate for a predetermined period of time to assure even distribution of the coating. Then the substrate is again rotated to its original orientation, and returned to its starting location.

Abstract: A programmable, microprocessor-based controller is responsive to a displacement command signal and first and second transport signals corresponding to the distance that glass sheets (9) are conveyed on main and auxiliary conveyors (16, 17) respectively, to provide a speed control signal to a separate, variable speed drive (31). The variable speed drive drives the auxiliary conveyor independently of the driven main conveyor (16). The variable speed drive (21) is controlled by the controller to: (1) reduce the rate of glass sheet conveyance; (2) reposition the leading and trailing glass sheets if necessary, along the direction of conveyance; and (3) insure that as each glass sheet is transferred between the main conveyor (16) and the auxiliary conveyor (17), the auxiliary conveyor (17) is driven at the same speed as the main conveyor (16).

Abstract: PURPOSE:To simplify an encoding and decoding device and improve the encoding efficiency by encoding signal switching information and calculating spectrum component spural times in a same section whena waveform signal is decomposed into spectrum components and then quantized and encoded. CONSTITUTION:A signal waveform in C is separated into signal waveforms 1 and 2 shown in D. The waveform signal of the signal waveform of 1 in D becomes 0 in 1st-4th small sections and the waveform signal of the signal waveform of 2 in D becomes 0 in 5th-8th small section in C. Those waveform signals have the spectra converted and the encoded signals of both spectrum signals are recorded on the recording medium together with the signal switching information. Further, a waveform signal with the reverse converted waveform signal of the spectrum of the waveform signal of 2 in D taken in the 1st-4th small sections in C and with the reverse converted waveform signal of the spectrum of the waveform signal of 1 in D taken in the 5th-8th small sections in C is composed. Then the signal waveform of 2 in D is a low-level signal, which is quantized to lower a noise level with the small number of bits.

Abstract: A method for operating a synchronized array of fixed block (FBA) formatted Direct Access Storage Devices (DASDs) to store and update variable-length (CKD) formatted records. This method is suitable for use with DASDs that obtain high recording density by using read and write head technology requiring "micro-jogging" to adjust for differing read and write head alignment or banded disk architecture having a higher block count in the outer tracks than in the inner tracks. Magneto-resistive heads may require micro-jogging to realign the write head for recording after reading the physical track location. The invention employs a DASD staggered array architecture having logical tracks consisting of diagonal-major sequences of consecutive blocks arranged in a predetermined wrap-around manner such as a topological cylinder or torus. The minimum necessary number of DASDs (N) in the staggered array is limited by the fixed block size (B), the interblock gap size (G), the average DASD data transfer rate (D), and the micro-jog delay time (T). A (N+1)th DASD may be added to record the parity of each diagonal-major sequence for improved fault-tolerance.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of lack of driving torque without decreasing driving torque outputted to a driving shaft, when the power required to a prime mover is quickly increased. SOLUTION: A control unit 190 calculates and sets torque tg of a motor MG1 as a target torque tgtag by which the number of revolution ng of the motor MG1 is made equal to a target number of revolution ngtag. The control unit 190 derives the maximum limit torque value tglim which the target torque tgtag of the motor MG1 can reach. The control unit 190 judges tgtag > tglim, and sets again the target torque tgtag as the maximum limit torque value tglim, when the target torque tgtag is larger. The control unit 190 so controls the torque tg of the motor MG1 that it becomes equal to the target torque tgtag.

Abstract: An imaging device comprises a semiconductor substrate including an array of pixel cells. Each pixel cell comprising an individually addressable pixel circuit for accumulating charge resulting from radiation incident on a pixel detector. The pixel circuit and the pixel detector can either be implemented on a single substrate, or on two substrates bonded together. The charge storage device can be a transistor, for example one of a pair of FET transistors connected as a cascade amplification stage. An imaging plane can be made up of one imaging device or a plurality of imaging devices tiled to form a mosaic. The imaging devices may be configured as a slot for certain applications, the slit or slot being scanned over the imaging plane. Control electronics can include addressing logic for addressing individual pixel circuits for reading accumulated charge from the pixel circuits. Imaging optimization can be achieved by determining maximum and minimum charge values for pixels for display, assigning extreme grey scale or color values to the maximum and minimum charge values and allocating grey scale or color values to an individual pixel according to a sliding scale between the extreme values. Scattered radiation can be detected and discarded by comparing the detected pixel value to a threshold value related to a minimum detected charge value expected for directly incident radiation and discarding detected pixel values less than said threshold value.
