  • Patent number: 4513435
    Abstract: A system for recognizing a continuously spoken word sequence with reference to preselected reference words with the problem of coarticulation removed, comprises a pattern memory for memorizing demi-word pair reference patterns consisting of a former and a latter reference pattern segment for each reference word and a word pair reference pattern segment for each permutation with repetition of two words selected from the preselected reference words. A recognition unit is operable as a finite-state automaton on concatenating the demi-word pair reference patterns so that no contradiction occurs at each interface of the reference patterns in every concatenation. It is possible to use the automaton in restricting the number of reference patterns in each concatenation either to an odd or an even positive integer.

  • Patent number: 4454482
    Abstract: The apparatus comprises a source capable of producing an atomic (molecular) beam and at least one electromagnetic resonator of the open type through which the atoms (molecules) pass. Optical pumping means excite the atoms (molecules) of the beam into a selected energy level before the beam passes through the resonator. An electromagnetic field generator is connected to the resonator for generating inside said resonator a spatial distribution of electromagnetic field at a frequency corresponding to the difference between the energies associated to said first level or energetic state and a second level or energetic state of the atoms (molecules) in the beam. Detection means provide an electric signal indicative of the number of atoms (molecules) which inside the resonator undergo a transition to the above mentioned second level or energetic state.

  • Patent number: 4404570
    Abstract: A laser recorder device in which many levels of half-tone densities are accurately produced with smooth transitions between areas of different densities. An input signal is sampled with a sampling pulse in response to which digital output values of a predetermined function of the input signal are produced. Pulses are applied to a semiconductor laser beam source with the number and frequency of the pulses during a preset application time being determined in accordance with the magnitude of the input signal.

  • Patent number: 4377607
    Abstract: In a process for producing vacuum deposition films which comprises providing a vacuum deposition film composed of an alloy or an intermetallic compound of two or more components having different vapor pressures at a specified temperature on a base, the improvement which comprises charging the component having the lower vapor pressure at said temperature to an evaporation source in a vacuum evaporation chamber in such an amount that the evaporation amount thereof per unit time does not substantially vary, and carrying out vacuum evaporation while continuously feeding a component having a higher vapor pressure at said temperature into said evaporation source in an amount corresponding to the evaporation amount thereof per unit time.

  • Patent number: 4369682
    Abstract: A rotary die cutter comprises a rotary soft anvil coacting with a rotary hard anvil mounting one or more cutting rules, or forms. Each cutting rule has within the area defined by the rule a metal or metal-containing pusher adapted to be moved radially outwardly of the rule at a predetermined location by a magnetic source to eject from the rule any cut waste board contained therein.
