Abstract: ABSTRACT                        LAMINATED PRE-IMPREGNATED CARBON         FIBER STRUCTURES        A laminate is constructed of two layers of oriented carbon fibers impregnated with a matrix resin.  One layer has a weight per surface of at least 50 g/m2 and the other layer has a weight per surface of from 5 to 50 g/m2 the second layer preferably also being very thin for example from 0.005 to 0.1 mm.  The fibers in the two layers are at an angle of substantially 90° to each other preferably between 80 and 90°.  In its preferred form the laminate is formed into a tube with the thin layer as the internal layer of the laminate and the fibers of the external layer being substantially parallel to the axis of the tube.  The tube provides greater strength and resistance to deformation and is particularly useful in fishing rods.

Abstract: TERMINAL GENERATION OF DYNAMICALLY REDEFINABLE CHARACTER SETS            Abstract of the Disclosure A graphic display terminal is arranged to receive drawing instructions containing the description of a display character.  The terminal, under control independent of the source, translates each received drawing instruction into a picture description bit pattern conforming to the characteristics of the terminal, display device.  The interpreted bits are then stored in a graphic repertory for subsequent retrieval under control of code received from the source.  In this manner dynamically redefinable character sets may be created and used without regard to a particular terminal implementation.

Abstract: METHOD AND APPARATUS FOR DATA TRANSMISSION USING CHIRPED FREQUENCY-SHIFT-KEYING MODULATION               Abstract of the Disclosure A method for transmission of digital data utilizes a carrier frequency offset in a first frequency direction for a first binary condition, and offset in a second frequency direction for the remaining binary condition, at the start of a bit time interval.  The carrier frequency is swept in a preselected frequency direction during each bit time interval, to produce a chirped frequency-shift-keyed waveform in the frequency domain, for trans-mission of each bit of binary data.  Frequency-shift-keyed demodulation is utilized at a receiving end, with the receiver synchronized to the transmitter bit time interval, to recover the transmitted digital data. Apparatus for data transmission using this chirped frequency-shift-keyed modulation waveform is disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE A process for controlling an industrial robot in which most data for controlling the robot can be supplied using a preset process without moving the robot and only data for regions in which very precise control is required need be prepared by actually moving the robot.  A programming unit is provided separate from but connectable to a robot control unit.  The programming unit is used to compile and transfer completed programs to the robot control unit for controlling the movements of the robot.  To program the robot control unit, the programming unit and robot control unit are connected as an on-line system.  Then, data descri-bing a desired path of movement is inputted to the programm-ing unit as a series of coordinates in Cartesian form.  In regions where very precise control is required, the coordi-nates describing the desired path of movement are corrected using small corrective motions of the robot.  The inputted data and the corrected coordinates are displayed.

Abstract: Abstract of the Disclosure A special instruction processor, such as a floating point accelerator processor, that processes a special class of instructions.  Each instruction identifies the number of operands to be processed as well as the number of data words required to be transferred for each operand.  The central processing unit retrieves and decodes each instruction, and transfers the special instructions to the special instruction processor.  Both processors decode the special instructions to determine the numbers of operands and data words to be transferred.  The central processing unit retrieves the data words from memory and transmits them to the special instruction processor.  The special instruction processor processes the instruction and signals the central processor when finished.  The central processor then causes the special instruction processor to transmit the processed data back to the central instruction processor.

Abstract: METHOD AND APPARATUS FOR DISK DRIVE ALIGNMENT                   Abstract A method and apparatus for checking perfor-mance and alignment of a disk drive designed for use with a floppy disk having a motor driven linear positioning mechanism for locating the read/write transducer over the diskette circular tracks.  A digitally prerecorded diagnostic diskette has a series of precisely located special diagnostic tracks provid-ing reference data for various alignment and response characteristics both mechanical and electronic.  A first group of tracks have sector ID blocks followed by progressively offset data blocks interspersed therein, with the range of the offset greater than the width of the track for which the disk drive is designed; which guarantees a read failure upon reading any track. These tracks are distributed radially across the sur-face of the diskette at positions corresponding to each rotational phase position of the transducer stepper motor.  A pair of indexed timing tracks having a fixed number of byte transitions permits testing of both the alignment of the index transducer and skew of the linear positioning device.  A pair of special timing tracks affords reference data for head compliance measurement.  A plurality of alternate offset tracks located centrally of the recording band provides refer-ence data for measuring the eccentricity of the drive spindle.
