IPC: G09G3/288
Filed: 1991-02-27
Abstract: ABSTRACT OF THE DISCLOSURE          In a display device of pictures, etc., an adequate brightness of pictures to be displayed is realized by varying the luminous times of the luminous elements constituting a display panel. The luminous elements receive multiple-bit codes representing levels of brightness from signals to be displayed.  Time corre-sponding to a field of television signals is divided into a plurality of sub-field of television signals is divided into a plurality of sub-fields corresponding to the bits of a multiple-bit code.  The plurality of sub-fields have lengths of time proportional to weights of the corresponding bits.  The luminous elements show different levels of brightness in sub-fields correspond-ing to bits, having values of "1" or "0", of a multiple-bit code.  For each luminous element, the time interval from a light emission start time in a sub-field where the first light emission occurs in a time corresponding to a field till a light emission start time in a sub-field where the last light emission occurs in a time corresponding to a field is made shorter than the critical fusion period of the perception characteristic of human eyes.

Title: Optical integrated circuit
Inventor: OKADA KENICHI
IPC: G02B6/122
Filed: 1991-04-18
Abstract: First and second optical waveguides are provided which extend at one end to one side of an electrooptic plate and are interconnected at the other ends, and the connection point is connected to one end of a third optical waveguide.  Light from the third optical waveguide is branched to the first and second optical waveguides, whereas light beams from the first and second optical waveguides are supplied together to the third optical waveguide.  The angle of the first optical waveguide to the above-mentioned one side of the electrooptic plate is deviated from 90°.  The end face of the first optical waveguide at that side forms a reflecting surface and is connected to one end of a fourth optical waveguide.  The other end of the fourth optical waveguide extends to another side of the electrooptic plate.  By forming end faces of the second and fourth optical waveguides at different sides of the electrooptic plate, optical active elements can be fixed directly to such end faces, even if the electrooptic plate is small.

Inventor: BROWN ROBERT L
IPC: B29C33/30
Filed: 1991-07-12
Abstract: A method and apparatus for a nonsynchronous system for continuously molding articles from a material cured by the control of temperature and pressure.  The apparatus includes a multi-section self-clamping mold, a controller system,  a material injector,  a transfer system, a curing apparatus for curing the articles, and a mold separator-assembler.  The method comprises pre-treating and then assembling the mold in a clamped condition.  Under the control of the controller system, the  mold  is  then  injected  with  material  from  the injector, and moved by the transfer system through the curing apparatus to cure the material within the mold. Once cured, the controller system moves the mold to the mold separator-assembler via the transfer system.  The mold is then disassembled into sections,  the molded article is removed, and the sections are pre-treated and reassembled, for the next injection operation.

Title: Method for developing thick beds of minerals
Inventor: TRIPOLKO ALEXANDR S
IPC: E21C41/16
Filed: 1991-07-15
Abstract: A method for developing thick beds of minerals accomplished by large-section rooms, comprising preparation of the room for winning which consists in executing a conveyer working below the soil of the room tothe entire length thereof, driving transport and fan drifts and raises, inclined working to fit the design contour of the room. The winning is effected in horizontal layers in a descending order by forward and reverse movements of the cutter-loader, each said layer is developed by stopes throughout the entire length of the room overlapping the cutter-loader movements. The first stope in each layer is developed in the range of raises, and subsequent - in the direction from the first stope toward the eges of the room.  Extraction of subsequent layers starts from the soil of the preceding layer by deepening the cutter-loader to a layer underneath to the height of its actuator. In the end part of the room within the limits of one stope there is formed an inclined descent to a layer below which is then suppressed while developing this layer opened by this descent.  The inclined working is opened in each layer by developing extreme movement.  The mineral is upplied to the raises and passed to the conveyer working.

IPC: G06F15/16
Filed: 1991-08-12
Abstract: - i -ABSTRACT    A programmable controller has a rack that electrically connects a number of I/O modules to a processor module.  The processor module includes a external device communication interface section and a general purpose processor section electrically coupled together by a set of common buses.  Both of these module sections include a microprocessor and memory connected by an internal set of buses which are isolatable from the set of common buses.  The isolation capability permits the different sections to perform their operations simultaneously.  A shared system memory and an rack interface are coupled to the common buses for the exchange of data with the I/O modules.  A unique ladder logic processor also is connected directly to the common buses.  The ladder logic processor includes a hardwired Boolean bit logic processor and a custom microcoded processor to execute instructions of a ladder type control program.  Program instructions which are too complex for execution by the ladder logic processor are executed by the general purpose processor section.

Filed: 1992-04-06
Abstract: This invention is directed to a screening method for the selection of mutations which confer acetohydroxyacid synthase (AHAS) inhibiting herbicide resistance to wheat. After mutagenesis of wheat seeds, the seeds are soaked in an AHAS inhibiting herbicide containing solution containing a particular class of AHAS inhibiting herbicide. After planting, the soil containing the seeds is sprayed with an AHAS inhibiting herbicide of the same class as that used in the seed soak step prior to the emergence of the seedlings from the soil. Those wheat seedlings which emerge and are normal in appearance demonstrate resistance to the class of AHAS inhibiting herbicides used in the seed soak and spraying steps. This invention is also directed to the wheat selections and seeds identified by the screening method.
