Abstract: In an information processing device for use in indicating an operation number of floating point operation elements, such as either vector elements of each vector instruction or scalar instructions, the floating point operation elements are successively counted by an adder (31) and a register (32) to produce operation number signals representative of results of the counting. The operation number signals are periodically read out of the register (32) as preceding and following operation number signals at preceding and following ones of periodical signals sent as a time signal from a digital timer, respectively, and are held in registers (36, 37). A substracter (41) substracts the preceding operation number from the following operation number to calculate a difference signal between the preceding and the following operation numbers and to provide the operation number per unit time. The difference signal is visually displayed on a display unit (42) in real time. Alternatively, each of the preceding and the following operation number signals may be memorized in a scalar register (48) together with the time signal.

Abstract: A wideband amplifier is configured to allow sophisticated low voltage signal processing in a ,low-­cost, high frequency integrated circuit driver. The integrated circuit driver prodides output currents to drive high voltage discrete power transistors in such a way as to achieve maximum frequency response from the low-cost discrete transistors. The discrete power transistors in turn provide an output voltage suitable for driving, for example, a CRT display. The trans­conductance amplifiers, video processing circuitry, current multipliers, and summers are formed in an integrated circuit device utilizing readily available processing and circuit design techniques, and a relatively small number of discrete low power components, including pull-up (Q3) and pull-down (Q4) transistors which are chosen to have a fairly high frequency of unity current gain (F t ), yet which are readily available at a very low cost. In order to utilize such low cost pull-up (Q3) pull-down (Q4) transistors, these transistors are driven either in cascode or in a unity gain current mirror configuration from separate pull-up and pull-down currents, in order to avoid the deleterious effects the input base capacitance of the transistor has on its frequency response.

Abstract: Multiple light detection channels (19-1 to 19-4, 21-1 to 21-4) are introduced into a flying spot optical triangulation ranging system to increase the speed of acquiring range values. A laser beam (L) is rapidly swept across a surface (11) by a beam deflector (16). Each fiber optic channel can receive light only from a different point (24-1 to 24-4) along a line at the intersection of the swept beam with the surface. The receiver channels are duplicated and separate detectors (21-1 to 21-4) generate signal pulses at times that are a function of range to the surface. These are processed in parallel to calculated N range values per beam sweep, where N is the number of channels.

Abstract: A wideband optical transmission system (11) for the subscriber region is provided with a bidirectionally operable optical waveguide (12) in which, in a wavelength range which is significantly lower than its limit wavelength, only the basic mode LP01 and the next highest mode LP11 can be propagated, and further with two optical transmitters (16, 18) and with two receivers (17, 19) whose operating wavelength lies within the above-mentioned wavelength range in which the optical waveguide (12) is to be operated, where the optical transmitters (16, 18) and the optical receivers (17, 19) are coupled to the optical waveguide so that two optical signals are transmitted bidirectionally with different modes LP01, LP11. In order to achieve a simpler, lower- cost design in a wideband optical transmission system (11) of this type, it is envisaged that one optical transmitter (16) couples signals in the LP01 mode into the optical waveguide (12) and the signals of this LP01 mode are decoupled through radiation to one optical receiver (19) and that the other optical transmitter (18) and the other optical receiver (17) in each case face a coupling or decoupling device (23, 22) disposed in the path of the waveguide (12) carrying signals in the LP01 mode, which device serves to couple signals in the LP11 mode from the other optical transmitter (18) into the optical waveguide (12) or decouple them from the optical waveguide (12) to the other optical receiver (17). <IMAGE>

Abstract: An automatic transmission hydraulic controller having a multiplicity of hydraulic servos for respectively controlling a multiplicity of frictional engagement elements. A hydraulic pressure to be supplied to the hydraulic servos is applied to accumulator chambers of a multiplicity of accumulators (21-24). A line pressure to be supplied to the hydraulic servos is produced by a primary regulator valve (3) and an engine output pressure control valve (5) is controlled by an electrical signal from a control section (8) to produce a hydraulic pressure corresponding to the engine output. Each of at least two particular ones of the multiplicity of accumulators has a back pressure chamber (71-74) formed at the rear of a piston. The pressure receiving area of this back pressure chamber and that of the corresponding accumulator chamber (91-94) are substantially equal to each other. Only one of the frictional engagement elements operated by the hydraulic servos communicating with the particular accumulators is changed over from a released state to an engaged state while the other frictional engagement elements are not changed over from a released state to an engaged state, when the transmission is shifted to a predetermined speed. There is no substantial influence of a change in the line pressure upon the operating state of the other frictional engagement elements.
