Inventor: YOSHIDA SHIGEYUKI
IPC: H01Q1/36
Filed: 1990-09-20
Abstract: An antenna apparatus to be used in a wireless equipment in which an element part of an external antenna is made of work hardening alloy and even if a large external force is applied to the element part, a removal of this external force causes the antenna to be recovered to its original state.  A bending or breaking of the element part are prevented to reduce a deterioration of electrical characteristics of the external antenna.  The element part can be bent and stored in a box of the wireless equipment, thereby the box of the wireless equipment can be reduced in size.

Title: Method of producing a substrate plate for a liquid crystal cell with black matrix areas
Inventor: BROSIG STEFAN
IPC: G03F7/40
Filed: 1990-11-26
Abstract: ABSTRACT                Method of producing a substrate plate for a liquid crystal cell with black matrix areas A method of producing a substrate plate for a liquid crystal cell with black matrix areas in which blackened polymer material is already deposited before the structured areas of photosensitive resist overlying the structured electrode areas are removed. Rather, these structured areas of photosensitive resist are removed only after the blackened polymer material has been hardened.            This processing sequence has the advantage that no special align-ment processes are needed in order to arrange the black matrix areas accurately between the electrode areas. This alignment is obtained autonomously by virtue of the fact that the electrode areas, even after they have been structured with the help of the photosensitive resist areas, are still covered by these selfsame photosensitive resist areas, thereby ensuring in an ideal manner that only the areas between the electrode areas will be filled with black matrix material and this in such a way as to make them butt directly against the electrode areas, so that the maximum possible surface will be covered by black matrix material.

IPC: H04L12/56
Filed: 1990-12-11
Abstract: The invention relates to a system and method for controlling the acces rate of stations in a data packet switching network. The improvement concerns the measures that the system comprising a number of transmitting/receiving stations interconnected by radio communication channels through which data packets can be transferred fror one station to another according to a routing scheme, each station comprising: - means to receive and transmit data packets; - first calculating means for calculating a first parameter which is indicative for its output flow being the number of packets successfully transmitted per time unit; - second calculating means for calculating a second parameter which is indicative for its input flow increase tendency, being a measure based on the output flows of the neighbouring stations the set station can relay which second parameter increases when these output flows decrease; - third calculating means for calculating a third parameter which is indicative for its load; - transmitting means for transmitting said first, second and third parameters to all neighbouring stations in reach of said station; - access rate altering means to alter its access rate; - comparison means; said system functioning during operation of the network in such a manner that in each station said first parameter is calculated by said first calculating means and is transmitted by said transmitting means at regular time intervals to all neighbouring stations in reach of the respective station, in each station thereafter said second and third parameters are calculated by said second and third calculating means respectively, whereafter the transmitting means in each station transmit said second and third parameters to its neighbouring stations in which said comparison means after reception of said second and third parameters determine which station in their neighbourhood has the largest input flow increas tendency and enable said altering means to update on the basis of the third parameter their access rate to bring the load of the station with largest input flow increase tendency closer to the nominal channel load.

Abstract: FILM CASSETTE WITH LOCK-OUT MEANS FOR PREVENTING LOAD OF EXPOSED FILM   ABSTRACT OF THE DISCLOSURE A film cassette comprises a film spool supported inside a lighttight cassette shell for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is only partly exposed, and a film exposure status indictor supported for rotation relative to the shell from an unexposed position to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed.  The status indicator includes integral lock-out means capable of being detected for the purpose of preventing insertion of the film cassette into various cameras intended to be used with the film cassette.  A cap for covering the lock-out means to prevent the lock-out means from being detected includes respective window-like means for revealing the lock-out means when the status indicator is in its partly exposed and fully exposed positions.  Thus, the film cassette can be used with a relatively simple camera intended to receive the film cassette only with fresh unexposed film and a more complex camera intended to receive the film cassette with unexposed or partly exposed film.

Filed: 1990-01-19
Abstract: 2045590 9007868 PCTABS00001 The invention relates to a machine for spreading, turning and raking together hay, straw and similar materials. The machine according to the invention has rotors (65, 84) which are rotatable around substantially vertical axles and are provided with rake arms (67) which extend radially and substantially horizontally from the rotation axles (58) of the rotors (65, 84). A number of parallel rods (68) are connected to the outermost ends of the rake arms (67) which rods constitute a rake. The rotors (65, 84) have a guide device (79, 85) so the rake arms (67) may be turned a previously determined angle around their longitudinal axis so that the rods (68) may interact with or go free of straw crops laid out in a field area. The guide devices (79, 85) are adapted to be turned around the axles (58) of the rotors (65, 84), and the guide device of one rotor (84) may be turned into the opposite direction of work so that it is possible to guide the laying down of the material into single swathes (105), double swathes (102, 104) or into a middle track (106). The machine has a threepoint suspension and is telescopingly adjustable with regard to the working width; and the angle between the direction of travel of the machine and a line between the rotational axles (58) of the rotors (65, 84) is adjustable to obtain the said exactness of the deposition of the crops.

Abstract: ABSTRACT     It is advantageous to prepare oligomers of polybenzazole polymers by reaction of AA-PBZ monomer with an excess of BB-PBZ monomer.  The resulting oligomer dopes may be stored at a temperature at which they remain pumpable until such time as the dope can be advanced to higher molecular weight by adding additional AA-PBZ monomer.  The molecular weight of the polymer may be adjusted by controlling the amount of chain extender and/or chain terminator added to oligomer mixtures as they are advanced to final molecular weight.   38,087A-F
