摘要:
A recognition apparatus interprets a musical score to produce musical performance data. An image reader is operated for providing score image data representative of the musical score. A memory device is composed of a plurality of memory units, each memory unit being arranged to store a predetermined volume of score image data. The provided score image data is sequentially written into the plurality of the memory units volume by volume. A processor successively retrieves each volume of the written score image data from the memory units and processes the same to interpret the musical score so as to produce the musical performance data. The processor is allowed to write another volume of the score image data into a vacant one of the memory units in parallel to processing the score image data.

A MIDI-code generating device utilizing a musical instrument for producing a plurality of musical tones which comprise a fundamental tone and a harmonic tone corresponding to the fundamental tone, the fundamental and harmonic tones being discrete frequencies and having different envelope wave-forms, includes a microphone for converting a produced musical tone from the musical instrument into an electrical audio signal, an A/D converter for converting the electrical audio signal into digital signal of wave-form data, a group of band-pass filters for extracting wave-form data having frequency component respectively corresponding to each of the fundamental tones, from wave-form data outputted by the A/D converter, an envelope detection circuit for detecting envelope data of wave-form data extracted by the group of band-pass filters, a memory for storing reference envelope data of the fundamental tone corresponding to the envelope wave-form of each fundamental tone of the musical tones produced by the musical instrument, a fundamental tone decision circuit for comparing envelope data detected by the envelope detection circuit with fundamental tone envelope data stored in the memory, and for deciding on a produced fundamental tone when the musical tone is produced by the musical instrument, and a coding circuit for generating a MIDI-code according to a result of a decision of the fundamental tone decision circuit and the detected envelope data.
摘要:
A suitcase assembly consisting of at least two suitcase components each of which having a generally rectangular configuration. Projections and/or recesses are provided on each of the suitcase components for detachably connecting the suitcase components in vertically overlapping relationship and also in side-by-side relationship. The projections and/or recesses for connecting the suitcase components have opposing flat surface portions and opposing unclaimed surface portions.

The weft yarn is selectively gripped and released by movable and stationary disc members in response to the weaving operation of the loom. The gripping force applied to the weft yarn by the members is such controlled that under beating of the reed, the magnitude of the force is decreased by a predetermined value thereby inducing a slippage of the weft yarn in the members.

The side surfaces of a trunk and curved portions of the weft yarn guide are so configured as to be convexly curved at the intersection of same with the confronting surfaces defining the gap between the trunk and curved portions, inboard of the widest portions of the trunk and curved portions so that the warp yarns can slidingly pass over the surface of the weft yarn guide without being made nappy or shaggy by contacting with sharp edges.
摘要:
An apparatus for selectively inserting into the shed of a weaving loom a plurality of weft yarns having different natures, particularly colors, comprising cam means including at least one cam which is formed with lobe and bottom portions alternately arranged about the axis of rotation of the cam and which is driven to turn about the axis through a predetermined angle under the control of weft selector signal supply means such as a pattern card arrangement, wherein cam retaining means is provided to hold the cam in one of the angular positions operative to have each of the weft shooting members held in a position ready to insert the pick of weft yarn into the shed, the retaining means being disengaged from the cam when the cam is being rotated from one of the angular positions thereof into another.
摘要:
A music analysis apparatus has a feature extractor and an analysis processor. The feature extractor generates a time series of feature values from a sequence of notes which is designated as an object of analysis. The analysis processor computes an evaluation index value which indicates a probability that the designated sequence of notes is present in each of a plurality of reference music pieces by applying a probabilistic model to the time series of the feature values generated from the designated sequence of notes. The probabilistic model is generated by machine learning of the plurality of reference music pieces using time series of feature values obtained from the reference music pieces.
摘要:
A pretreatment method for saccharification of plant fiber materials includes: immersing the plant fiber material in a solution that contains an organic solvent, in which a cluster acid is dissolved, prior to saccharifying cellulose contained in the plant fiber material; and distilling off the organic solvent from the immersed plant fiber material to obtain a pretreated mixture that contains the cluster acid and the pretreated plant fiber material.
摘要:
The invention relates to a method for hydrolyzing a plant fiber material to produce and separate a saccharide including glucose. The method includes a hydrolysis process of using a cluster acid catalyst in a pseudo-molten state to hydrolyze cellulose contained in the plant fiber material, and produce glucose. The cluster acid catalyst is subjected to a clustering enhancing treatment by which clustering of the cluster acid catalyst in a crystalline state is enhanced.
