Patent EP-0456034-A2 (EP)
Inventor: ROSEN HAROLD A
IPC: H01Q3/00
Filed: 1991-04-23
Abstract: A bicone microwave antenna having an orthomode tee (14) as an input/output terminal, an internal dielectric polarizer (16), a circular waveguide with eight longitudinal radiating slots (20), two 30 degree conical reflectors (52,54), an external meanderline polarizer, and a partial circular waveguide short. An RF signal from the input/output terminal is converted into a rotating TE₁₁ mode by the internal dielectric polarizer. The radiating slots in combination with the conical reflectors radiate the RF signal as a horizontally polarized field in a doughnut-shaped pattern. The meanderline polarizer converts the horizontally polarized field into a circularly polarized field. The partial circular waveguide short leaks a predetermined amount of radiation out the end of the waveguide to fill the center hole of the doughnut-shaped radiation pattern, thus producing a hemispherical RF beam having an elevation angle from 110 to -110 degrees. The use of impedance-matching circular rings in the waveguide further enhances the ability of the antenna to operate in three frequency bands.

Abstract: A plane of a treatment liquid holder (113; 214; 312; 413; 516) having a number of through holes (110; 213; 309; 314) faces a treatment surface of a substrate (112; 217; 314; 412; 511). A treatment liquid (115; 216; 320; 415; 523) is held between the treatment surface and the liquid holder (113; 214; 312; 413; 516) by utilizing a surface tension of the treatment liquid (115; 216; 320; 415; 523). Since the treatment liquid (115; 216; 320; 415; 523) is applied only to the treatment surface, an extremely small amount of treatment liquid (115; 216; 320; 415; 523) suffices for the treatment. In addition, since a fresh treatment liquid can be used in every treatment, cross-contamination is suppressed and the treatment can be performed with safety at a low cost.

Abstract: The device reacts to a short-circuit of an electrical load within a large number of electrical loads which are already being driven by an uninterruptible power supply, in such a manner that a current monitoring device (12), which is arranged in the primary circuit (51) of a transformer (5), causes, via a relay (6), a voltage reduction in the secondary circuit (52) of the transformer (5), which voltage reduction produces a current that is increased by a multiple in the secondary circuit. The current that is increased by a multiple opens that isolating device (81, 91, 101, 111) which belongs to the load group (8, 9, 10, 11). This load group is disconnected from the uninterruptible power supply so that the uninterruptible power supply unit (2, 3, 4) is protected against a short-circuit and the uninterruptible power supply is maintained for the other loads. <IMAGE>

Abstract: A novel conjugate vaccine comprising partially hydrolyzed, highly purified, capsular polysaccharide (Ps) from  Streptococcus   pneumoniae  bacteria (pneumococci, Pn) linked to an immunogenic carrier protein, is produced by a new process. The conjugate is useful in the prevention of pneumococcal infections. Vaccines comprising a mixture of from one to ten different pneumococcal polysaccharide-immunogenic protein (Pn-Ps-PRO) conjugates induce broadly protective recipient immune responses against the cognate pathogens from which the polysaccharide components are derived. Young children and infants younger than 2 years old, normally unable to mount a protective immune response to the Pn-Ps alone, exhibit protective immune responses upon vaccination with these Pn-Ps-PRO conjugates.

Abstract: A liquid crystal display operable in normally white mode comprises a liquid crystal display panel (26). A scan line driver (24) addresses scan lines of the panel (26). A data line driver (22) applies a range of different voltages to data lines of the panel (26) to produce different gray scale levels in a gray scale picture. The data line driver (22) comprises a reference voltage circuit (28) for offsetting the range of applied voltages in such a manner that the transmittance of the panel (26) decreases substantially linearly from the lower extreme of the range to the upper extreme. By shifting the lowest applied voltage in the Voltage-Transmittance curve in the direction of monotonously decreasing area of the V-T curve, brightness or gradation is prevented from being inverted. Thus, the liquid crystal display simultaneously provides both good contrast ratios and good gradation at large viewing angles.

Abstract: A paper feed operation is performed by a width less than one pixel (1/2) in addition to an integer multiple number of pixels (n/2) with respect to a basic number of pixels inherent to an ink jet recording apparatus having a multi nozzle head having n nozzles. When a plurality of times of pixel recording operations are performed for a single pixel region, ink dots land at a distance less than one pixel (1/2) at the pixel density. Thus, a variation in ink surface density on a recording sheet in an overlapping print operation is reduced, thereby efficiently increasing the image density, and preventing blurring by promoting absorption and evaporation of an ink to and from a paper sheet.

Abstract: A packet switched communication system employing ANR and/or multicast tree routing is improved by using a Copy ID field in the network header of the packet. The Copy ID field defines a control function and allows packet processing to be distributed among the several processors of each node. The selection of the processor (or processors) to receive the packet may be accomplished by making use of the routing field of the network header to qualify the control function specified in the Copy ID field. The control message is processed as defined for the control function by the processor receiving the packet. In multicast tree routing the control function is performed at all nodes in the multicast tree. In ANR routing, a prefacing "selective copy" bit is included in each label in the routing field of the network header; each node employed in the packet transmission path uses one label. The selective copy bit in each label triggers or not (according to its setting) the copy function in that node. The network control function specified in the Copy ID field may be performed in a given node when the copy function is triggered for that node.

Abstract: An excess voltage applied to a piezoelectric element is detected and controlled to improve durability and reliability of the piezoelectric element. 
     A fuel injection control device for an internal combustion engine in which a power source voltage is boosted by a dc-dc converter (1) and the so-boosted output voltage is supplied via a first choke coil (Lc) and a first thyristor (SCR1) to a piezoelectric element (PZT) for charging the piezoelectric element (PZT) for being subsequently discharged via a second thyristor (SCR2) and a second choke coil (Ld). The fuel injection control device includes a positive voltage detection unit (10) for detecting the positive voltage at a junction between the first choke coil (Lc) and the first thyristor (SCR1) and a positive voltage control unit (20) controlled by an output signal of the positive voltage detection unit (110) and adapted for shorting both ends of the first choke coil (Lc). The current through the first thyristor (SCR1) is cut off to prevent the excess voltage from being applied to the piezoelectric element (PZT).
