Filed: 1990-09-06
Abstract: PURPOSE:To realize the best suppression and quick attenuation control over a click noise by varying and controlling a damping rate according to the sound volume level or envelope waveform signal level of a musical sound signal. CONSTITUTION:This musical sound controller is equipped with a means 25 which detects the level of an envelope waveform signal for amplitude level/ musical sound control over the musical sound signal, a damping rate determining means which determines the quick attenuation rate in damping control corresponding to the detected level, and a damping control means 10 which attenuates the sound volume envelope waveform signal speedily at the determined rate when the sound volume of the musical sound is decreased. Then the quick attenuation rate (damping rate) is made lower and lower as the amplitude level of the musical sound signal is higher and higher, and made higher and higher as the amplitude level is lower and lower to make the inclination of the quick attenuation gentle when the amplitude level of the musical sound signal is large, thereby suppressing the click noise. When the amplitude level is small, on the other hand, the original click noise is inconspicuous and the quick attenuation is completed early.

Filed: 1983-12-13
Abstract: PURPOSE:To increase the speed of printing output by a method in which when one letter code constituting a combined letter is inputted in a printer to print combined letters, the movement of a carriage from printing positions is prohibited. CONSTITUTION:In CPU, when printing data containing letter codes are inputted, the data re once stored in data buffer region RAM2 inside RAM6 and then read out one by one. It is judged whether the printing data so read out are exclusive letter codes for combination if the combination letter code is not setting/releasing code for the combination letter setting region RA3, and if they are exclusive letter code for combination, moving pitch O is set up in the carriage drive circuit. If they are not exclusive letter code for combination, the combination letter setting region RA3 is retlieved, and if it is set code, the moving pitch O is set up. The speeds of printing can thus be increased without the needs to set the carriage back to its original printing position.

The grating pitch P at a sepn. angle thetag= sin<-1>(nlambda/P) is selected at about 100mum. The spot spacing on the disk is d'=ftanthetag and the track pitch of the specified spacing is maintained at all times if the disposition of the diffraction grating is properly changed. The registration of the plural beams with high accuracy is each and the decrease in the transmittance at the time of obtaining the beams is low. The optical disk is thus produced by simultaneously forming the plural tracks.
