Patent EP-0375434-A2 (EP)
Inventor: CURRY DOUGLAS N
IPC: H04N1/23
Filed: 1989-12-21
Abstract: The bit clock for a digital printer having a flying spot scanner is generated by an arithmetic frequency synthesizer (24) which has its operating point updated, at predetermined spatial locations during each scan cycle, by scanner-specific, bit clock frequency correction values which are serially applied to the frequency synthesizer for spatially linearizing the frequency of the bit clock while the scanner is scanning successive segments or partitions of its scan field. The correction values are "scanner-specific" because they are computed to adjust the temporal frequency of the bit clock as required to compensate for measured variations in the average linear speed at whch the scanner scans the successive segments of its scan field, including variations caused by optical aberrations of the scan optics.

Abstract: A fine-grained microstructure processor (FMP) (10) for solving assignment and correlation problems utilizes a pair of arrays (22, 24) of cells (26) to represent the position of two sets of two-dimensional data points. The arrays (22, 24) are divided by a predefined shape (16) having a plurality of regions. The FMP (10) counts the number of data points in each region and then finds the difference between the resulting sums from corresponding regions in the two arrays (22, 24). The differences for each region are added together by an accumulator (34) to determine a correlation factor. The data in the second array (24) is then shifted until a different data point occupies a particular position with respect to the predefined shape (16) and a new correlation factor is found. The FMP (10) finds a correlation factor for each data point in the second array (24) and the lowest correlation factor represents the best match between a data point in the first array (22) at a particular position with respect to the predefined shape (16), and the point in the second array (24) yielding the best match. The FMP (18) may then shift the data in the first array (22) and repeat the above process to match each data point in the first array (22) with a data point in the second array (24).

Abstract: A feeding device according to the invention, comprising: 
a cassette (26, 27) capable of being mounted in and removed from the main body of a copying machine to which the feeding device is adapted; 
a pivotal paper holding plate (34) which is disposed within the cassette and capable of being raised; 
a lift member (40) for raising the pivotal paper holding plate (34), disposed under the pivotal paper holding plate (34) so as to pivot on a vertical plane; 
a rotary lift-up member (60) for allowing the lift member (40) to pivot thereon, the lift member (40) being secured to the rotary lift-up member (60); 
a driving device (42) for transmitting a driving force to the rotary lift-up member (60); and 
a coupling device (44, 45) interposed in the driving device (42), for effecting and suspending the transmission of the driving force for rotating the rotary lift-up member (60), wherein when the cassette (26, 27) is taken out from the main body, the lift member (40) pivots downward due to its own weight, thereby releasing the pivotal paper holding plate (34) from its raised condition. With such an arrangement, even if the cassette (26, 27) is taken out from the main body when the pivotal paper holding plate (34) is in its raised condition, the paper feeding end of the pivotal paper holding plate (34) can be prevented from touching with the paper feed mechanism disposed within the main body, thereby avoiding damage to the contacted parts.

Abstract: A first instruction bit string following a memory position indicated as a start point by a read pointer (5) is previously read out from a plurality of memory cells (a 11 ~a mn ) to a plurality of bit lines (BL), a second instruction bit string already transferred to an instruction decoder (9) is temporarily stored in a latch circuit (7) by an instruction length notification signal output from said instruction decoder (9), and a select circuit (6) selects a next instruction bit string sequentially continuing from a next instruction, between the first and second instruction bit strings without requiring other bit lines (BL) or word lines (WL). Therefore, a high speed instruction processing in the pipeline processing can be realized without increasing the number of transistors and wirings constituting memory cells in an instruction buffer memory (IB), and thus a large scale integration, a small size, and a low cost can be realized.

Patent EP-0460414-A2 (EP)

IPC: C12Q1/04
Filed: 1991-05-06
Abstract: Novel autonomously replicating biological particles resembling bacteria and having most surprising properties were discovered from cell culture sera and other biological samples alleged to be sterile according to the current testing methods. These slowly growing agents named  Nanobacteria  are smaller than any known cell-walled bacteria. They pass through sterile filters, even with pore sizes smaller than their diameter. They cannot be cultured on any standard microbiological media. With the isolation and detection methods provided here they are commonly detectable in animal or human serum. This patent holds for methods of their culture, detection, purification, and elimination and described the necessary reagents for that. 
     Autonomously replicating particles can be cultured in RPMI 1640, or in DMEM, or in other cell culture media. Optimal growth can be obtained by supplementing the culture medium with 10-20% sterile fetal bovine serum. Addition of small amounts of D,L or L selenomethionine together with nucleotide precursors may improve growth. Culture is started by addition of the test sample to the medium in a cell culture vial which is thereafter incubated under standard mammalian cell culture conditions for at least 15 days. Biological samples are preferably sterile-filtered before culture through 0.22 micron filters. The growth of  Nanobacteria , if present, can be seen using microscopy at high magnification. The organisms can be made more visible by DNA staining and immunostaining done either separately or simultaneously to a fixed preparation.  Nanobacteria  can be cultured without mammalian cells, but co-culture together with an adherent cell line like 3T6 is useful because 3T6 cells can take  Nanobacteria  inside the cells. This aids the staining of the preparations. Intracellular agents are not lost during fixation and staining. 
       Nanobacterial  antigens can be prepared by specific culture, harvest, purification and solubilization methods. Immunization of rabbits with the solubilized antigen (treatment with proteinase K and with 1 N HCI) produces highly specific antibodies to  Nanobacteria . Gamma-irradiation of culture serum at 2.5-4.0 megarads, preferably in addition with treatment using solid-phase bound antibodies enables preparation of Nanobacteria-free serum. Use of this serum creates sterile culture medium for the culture and detection of Nanobacteria. Double staining combining Hoechst No. 33258 stain and immunofluorescence specifically distinguishes  Nanobacteria  from other cell culture contaminants.
