摘要:
A photocurable and thermosetting resin composition comprises (A) a high purity synthetic silica powder having a uranium content of not more than 1.0 ppb, (B) a photosensitive prepolymer containing a carboxylic group and at least two ethylenically unsaturated groups in its molecule and having an acid value of solid content of 50 to 150 mg KOH/g, (C) a photosensitive (meth)acrylate compound, (D) a photopolymerization initiator, (E) an epoxy resin, and (F) a curing catalyst. A cured film which emits alpha rays at a fully low dose is obtained by forming a film of the composition on a substrate, subjecting the film to exposure to light and development, and finally curing the coating film by irradiation with active energy rays and/or thermal curing.
摘要:
A data recording and reproducing apparatus for recording and reproducing data on azimuth tracks of a magnetic tape in which the data may be audio data or computer data in any of several different computer data formats includes a controller that controls the recording and reproducing signal processing so as to be responsive to the four different kinds of data formats such that main data and subdata may be separated from the audio data and subcodes and error correction codes generated and appended to the data stream as required.
摘要:
An apparatus and method for recording digital data employing a DAT (digital audio tape recorder) adapted to record the data from a computer or the like in accordance with the DAT format, wherein a unit is formed of predetermined plural frames and a signal indicative of each frame number within a unit and a signal indicative of the last frame of the unit are recorded with each frame, whereby the length of the unit can be arbitrarily changed and accordingly signal processing is facilitated easily.
摘要:
An apparatus and method for recording and/or reproducing digital data employing a DAT (digital audio tape recorder) adapted to record and/or reproduce data from a computer or the like in accordance with the DAT format. Main data is recorded in a main area of a track while error detecting data for the main data recorded in the main area of the track is recorded in a sub-area of the track to thereby easily detect an error in the main data.
摘要:
Initial touch data or after touch data is obtained by operating a play input unit, such as keys or strings. A musical tone whose timbre or volume changes by the touch data is obtained. A tone generator has a plurality of sound source lines. Desired waveform data is selected by the touch data for each line. Only one type of the selected waveform data that is segmented at a touch split point is outputted for each line. The musical tone may be detuned by finely staggering the reference frequency, for each line. An envelope waveform may be applied to the musical tone for each line.
摘要:
An electronic musical instrument can execute a musical performance with two timbres mixed together by operating a single key, for example. Of the two timbres, a master timbre is set in normal mode and is stored in a first memory, while a slave timbre is selected in tone mix mode and is stored in a second memory. Each timbre can be altered as desired. To alter the master timbre, timbre switches are operated after the mode is temporarily changed to normal mode. To alter the slave timbre, the timbre switches are operated in tone mix mode. When the tone mix mode is set, this electronic musical instrument can permit a player to easily alter tone parameters such as the volume, pitch and attack delay time of each timbre.

An apparatus and method for recording and/or reproducing digital data employing a DAT (digitial audio tape recorder) adapted to record and/or reproduce data from a computer or the like in accordance with the DAT format. Main data is recorded in a main area of a track while error detecting data for the main data recorded in the main area of the track is recorded in a sub-area of the track to thereby easily detect an error in the main data.
