Abstract: Disclosed is a method for dispersal of fog, the method comprising the steps of aligning a plurality of sets of electrodes of an applying means in a dischar ge means along one continuous plane (B), each of the sets of the electrodes being supported  by a single pole and being arranged in an upwardly-oriented direction above the pole, th e electrodes of each set being aligned in parallel and being disposed at the same height,  applying the same voltage to the plurality of sets of electrodes to direct electric force  lines upward above the applying means. The method further comprises generating charged particles based on corona discharge from the applying means, and allowing the charged particles to absorb water in the air, resulting in the binding and condensation of the  absorbed water, whereby the fog is dispersed.

Granted: 2006-02-14
Abstract: First and second gears are interposed, respectively, between first and second endless power transmission belts each for driving a camshaft of a cylinder head of each of V-shaped cylinder banks and a crankshaft 7. A pair of balancer shafts are provided at symmetrical positions with respect to a separating plane acting as a center therebetween where an upper block and a lower block of a cylinder block are separated from each other from a horizontal plane passing through a center of the crankshaft in such a manner that axes of the pair of balancer shafts become parallel with the crank shaft. The crankshaft and the balancer shaft on the lower block side are connected to each other by means of a third endless power transmission belt . The balancer shafts are connected to each other by means of third gears, so that the pair of balancer shafts are driven to rotate in the opposite directions. Accordingly, the first and second endless power transmission belts and the third endless power transmission belt are prevented from overlapping each other in an axial direction of the crankshaft. In particular, the respective endless power transmission belts and the respective gears are disposed, respectively, on planes each intersecting at right angles with the axis of the crankshaft, whereby the expansion of the engine in the axial direction of the crankshaft can be prevented.

Granted: 2007-01-09
Abstract: The invention relates to a device and a method for supplying informatics to pilots, especially in poor visibility, about, for instance, the borders of a runway (1). Along the long sides of the runway and at its beginning and end, signal means (2, 5) are arranged, which are translucent to e.g. UV radiation and which comprise a fluorescent material which converts the radiation penetrated by illumination into visible light. In the daytime, the UV radiation originates from sunlight. The converted light will then reinforce the usual light from the signal means, which originates from the sun's illumination thereof with visible light. As a result, in will be much easier to observe the signal means especially against the light. It is further suggested according to the invention that at night the signal means are illuminated by UV searchlights (34, 35). By a great number of signal means being illuminated simultaneously by a small number of searchlights, a great amount of electric equipment and installation work can be avoided. It is suggested that the signal means be made as flat screens in the form of square or rectangular pieces of plastic sheeting expanded between poles.

Abstract: A method is provided for generating comfort noise in a packetized voice communication system having a transmitter and a receiver. The receiver is provided with a buffer for storing voice packets. The buffer is chosen to be of a predetermine size such that, upon halting the transmitter as a result of silence detection, the buffer is filled with actual silence samples from the transmitter. A comparator compares an output TDM sample pointer with a start of silence pointer of the buffer. In the event that the pointers are the same, silence is flagged and a random number generator loads numbers into the TDM sample pointer for outputting a random sequence of the silence packets to the telephone receiver.

Title: Method of generating control data for bending and torsion apparatuses
Inventor: MEGURI HIDEO
IPC: G05B19/19
Filed: 2000-09-25
Granted: 2008-02-19
Abstract: A shape data specifies the shape of an elongated product within an overall coordinate system. Local coordinate systems are defined on respective cross-sections of the elongated product in the overall coordinate system. The local coordinate system is designed to represent a stable die of a bending apparatus. The images of the elongated product protruding forward from the stable die within the respective local coordinate systems serve to specify the position of a movable die of the bending apparatus. The specified position reflects the deformation induced in the elongated product between the stable and movable dies. An ideal movement amount of the movable die can be determined based on the determined positions within the local coordinate systems. The determined movement amount can be utilized to prepare the control data for the bending apparatus. When the prepared control data is supplied to the bending apparatus, an ideal movement of the movable die can be achieved so as to effect bending on the elongated workpiece at a higher accuracy in accordance with the shape data.

Abstract: A seed meter and accelerator comprises a stationary housing, a stationary axially extending dispensing rim, a radially extending flange and a rotating disc. The stationary housing is provided with an axially extending metering rim. The metering rim is provided with a metering gap. The stationary axially extending dispensing rim is located radially outward from the metering rim and is provided with a dispensing gap. The radially extending flange extends between the axially extending metering rim and the axially extending dispensing rim. The rotating disc is provided with an inner portion having circumferentially arranged seed pockets and an outer portion having seed dispensing openings. Each seed pocket corresponds to a seed dispensing opening. Passages extend between the seed pockets and the seed dispensing openings. The seed pockets of the inner portion are located adjacent to and radially inward from the metering rim. The seed dispensing openings are located adjacent to and radially inward from the dispensing rim. A source of air pressure pressurizes the stationary housing driving seeds into the seed pockets. When a seed pocket is registered with the metering gap the air pressure and centrifugal force drive the seed outwardly through the passage to the seed dispensing opening. At the opening the seed is held in place by the air pressure and the centrifugal force of the rotating disc until it reaches the seed dispensing gap. As the seed is released from the seed dispensing gap it proceeds into the seed furrow.

Abstract: The invention relates to methods for enabling handover for Simple IP or Mobile IP in a CDMA2000 network. In one embodiment, the new PDSN (17) establishes contact with the old PDSN (16) to obtain information about its PPP connection with the MN (11). The new PDSN (17) then sets up a tunnel between the PDSNs (16-17) and copies the PPP connection, while the old PDSN (16) dismounts its own PPP connection. The traffic now goes from the MN (11) to the new PDSN (17) that tunnels it to the old PDSN (16) that in turn forwards it through its old connection to the HA (20) or the backbone (22).        In a second embodiment, the new PDSN (17) contacts the old PDSN (16) to obtain information about the connections associated with the MN (11), and uses the information to copy the connections, while keeping contact with the old PDSN (16) to update the same information.        Also provided are systems and PDSNs (16-17) for carrying out the methods according to the inventions.        Suggested publication figure: Figure 3.
