摘要:
A tuner apparatus 10 causes a user to designate a musical instrument that is to be tuned and a reference pitch that is a standard upon tuning, by a process at a setting portion 110. A pitch detecting portion 130 detects a pitch of a performed note inputted via a microphone 20 and input portion 120. A target note specifying portion 140 defines a note name, which is positioned nearest to the performed note in a predetermined temperament (e.g., 12-note equal temperament), as a target note based upon the detected pitch of the performed note and the inputted reference pitch. Then, a calculating portion 150 calculates a difference between the pitch of the performed note and the pitch of the target note, and a display control portion 160 causes the display device 30 to display the calculated difference. Further, the display control portion 160 converts the target note into a note name written in a score relating to the musical instrument to be tuned by using a transposition parameter relating to the musical instrument to be tuned that is stored in the storage portion 100 and set by the setting portion 110, and causes the display device 30 to display a staff in which a note corresponding to the note name written in a score is written.
摘要:
In an instrument performance learning apparatus, a storage section stores model performance waveform data representing a time series of individual performance sounds of a model performance. An input section inputs real performance waveform data representing a time series of individual performance sounds of a real performance. A pitch graph display control section detects each pitch of each individual performance sound from the stored model performance waveform data and from the inputted real performance waveform data, and displays a pitch graph representing transitions of the detected pitches. An amplitude envelope graph display control section detects each amplitude level of each individual performance sound from the model performance waveform data and from the real performance waveform data, and displays an amplitude envelope graph representing transitions of the detected amplitude levels, such that the amplitude envelope graph has a time axis common to that of the pitch graph while the amplitude envelope graph is located in an area of the display device which does not overlap with another area of the display device where the pitch graph is located.

摘要:
An electronic musical instrument includes a tuning device, a keyboard, a tone generator, a microphone, a measurement unit, and a display attached to the backside of the housing. The tone generator generates a plurality of reference tones in response to the operation of the keyboard, while the microphone receives a plurality of musical tones, which are generated by at least one musical instrument subjected to tuning. Different tone colors can be applied to the reference tones. The measurement unit measures a plurality of pitch differences between the reference tones and the musical tones subjected to tuning, so that the display displays the pitch differences in comparison with each other.

An indoor air-conditioning unit 10 which can effectively deactivate allergens includes an intake grill 11 for drawing in indoor air. Indoor heat exchangers 13, 14, and 15 exchange heat between air drawn in from the intake grill 11 and a refrigerant to thereby cool or heat the air. A diffuser 16 returns the air which has been heat-exchanged with the indoor heat exchangers 13, 14, 15, back into the room. A cross-flow fan 17 blows air which has been drawn in from the inlet and heat exchanged from the diffuser 16 into the room. An allergen deactivation filter 18 is arranged in an internal space 5 through which the air flows and supports an allergen deactivation enzyme. An enzyme activation device maintains the internal space S in an atmosphere for activating the allergen deactivation enzyme.

A method for exposing an exposure pattern on an object by a charged particle beam, including the steps of: shaping a charged particle beam into a plurality of charged particle beam elements in response to first bitmap data indicative of an exposure pattern, such that the plurality of charged particle beam elements are selectively turned off in response to the first bitmap data; focusing the charged particle beam elements upon a surface of an object; and scanning the surface of the object by the charged particle beam elements; the step of shaping including the steps of: expanding pattern data of said exposure pattern into second bitmap data having a resolution of n times (n.gtoreq.2) as large as, and m times (m.gtoreq.1) as large as, a corresponding resolution of the first bitmap data, respectively in X- and Y-directions; dividing the second bitmap data into cells each having a size of 2n bits in the X-direction and 2m bits in said Y-direction; and creating the first bitmap data from the second bitmap data by selecting four data bits from each of the cells, such that a selection of the data bits is made in each of the cells with a regularity in the X- and Y-directions and such that the number of rows in the X-direction and the number of columns in the Y-direction are both equal to 3 or more.

To improve in the throughput of an exposure system, the setting time during a step change in the output of an amplifier is reduced by switching resistance between the amplifier and deflector, a glitch waveform generated during a step change in the output of a D/A converter at the preceding stage of the amplifier, is anticipated and is canceled out with a correction waveform, after the output of the D/A converter has settled, this output is sample held and the step change is interpolated at a smoothing circuit, the deflection area is increased by positioning a electrostatic deflector offset around the optical axis relative to another electrostatic deflector, the response speed of the main deflection is improved by adding auxiliary deflection coils of one or two turn, and the alignment time is reduced by combining the coordinate conversion in the wafer area and in the chip area. In order to correct the astigmatism of the electromagnetic lens, two stages of coils are provided and an electric current corresponding to the quantity of deflection is supplied to the coils.
