  • Patent number: 6156258
    Abstract: An injection blow molding system includes an injection molding station 22, a first delivery section 24, a cooling station 26, a heating station 30, a second delivery section 32 and a plurality of blow molding stations 34. The injection molding station 22 is designed to simultaneously injection mold M rows of N preforms 36 arranged in a second direction B perpendicular to a first direction A in which the preforms 36 are carried. The first delivery section 24 is designed to remove the M rows of preforms 36 injection molded by the injection molding station 22 through a removing mechanism 102 in their upright state while decreasing the pitch in the rows. The preforms 36 are inverted with the column pitch being changed by an inverting mechanism 104 before they are delivered to the cooling station in their inverted state. The cooling and heating stations 26, 30 are designed to cool and heat one row of N preforms 36 while parallel carrying them along a first carrying chain 200.

  • Patent number: 5751898
    Abstract: Speech recognition is achieved using a normalized cumulative distance. A normalized Dynamic Programming (DP) value is calculated by dividing a cumulative path distance by an optimal integral path length. The path length is calculated iteratively by adding 2 if the warping path is diagonal or by adding 3 if the warping path is horizontal or vertical. Distance may be calculated by measuring a difference between input power and average power. The power difference is weighted by a coefficient (.lambda.) between 0 and 1. A Mahalanobis distance is then weighted by (1-.lambda.) and added to the weighted power difference.

  • Patent number: 5621849
    Abstract: A voice recognizing method apparatus in which an input voice is recognized by obtaining a similar pattern by comparing the input voice and voice standard patterns. Voice standard patterns are stored into a memory. A voice is inputted. Voice duration lengths and distances are calculated by performing matching processes between the input voice and the standard patterns. The distance is corrected in accordance with the voice duration length so that the voice duration length having the best matching result is used as a reference, or such that the distance is small as the voice duration length is long. A recognition result is determined in accordance with the corrected distance. The matching is executed by a word spotting method. The input voice to be matched and the voice standard patterns are expressed by voice characteristic parameters.

  • Patent number: 5208863
    Abstract: A method for encoding syllables of a language, particularly the Japanese language, and for facilitating the extraction of sound codes from the input syllables, for voice recognition or voice synthesis includes the step of providing a syllable classifying table, in which each syllable is represented by an upper byte code indicating the consonant part of the syllable and a lower byte code indicating the non-consonant part of the syllable. The consonants constitute a first category of data classified by phonetic features, while the non-consonants constitute a second category of data classified by phonetic features, so that the extraction of consonant or non-consonant sounds can be made by a search in only the first or the second categories.

  • Patent number: 5019907
    Abstract: Horizontal synchronizing signals included in a video signal are inputted to a PLL circuit. A counter as a divider in the PLL circuit outputs signals which are synchronized with the horizontal synchronizing signals. A gate pulse generator counts the output pulses of counter and produces a control signal for controlling a phase comparator as one of elements of the PLL circuit. The operation of phase comparator is stopped in vertical intervals in accordance with the control signal so that the phase comparator is not affected by signals which are included in the video signal and are not synchronized with the horizontal synchronizing signals. Thus, the PLL circuit produces pulses which are synchronized with the horizontal synchronizing signals in a wide frequency range.
