Title: Electronic musical instrument
Inventor: OBARA YOSHITO
IPC: G10H7/00
Filed: 1987-10-29
Abstract: PURPOSE: To simply change tone quality at the time of reproducing a sound by applying plural kinds of signal working for emphasizing or suppressing a required frequency band to a single digital musical sound signal, storing the worked results in plural waveform memories, and at the time of reproducing, individually controlling the output level of each waveform. CONSTITUTION: Two kinds of inputs for obtaining a required I/O characteristic in a signal working processing part 10 are applied to a 1st input part 109. A frequency band to be emphasized or suppressed is numerically inputted as an input format to obtain the required I/O characteristic. A digital musical sound signal outputted from an A/D conversion part 101 is processed by two kinds of signal working processing in a signal working processing part 10 and the processed results are respectively stored in 1st and 2nd waveform memories 11, 12. When the output of a musical sound is instructed to a 2nd input part 110, the 2nd input part 110 outputs a musical sound information signal related to the tone level and touch of the specified output musical sound to an output control part 108.  Consequently a musical sound having tone quality different from that of an inputted musical sound is outputted by simple control.

Title: Power unit
Inventor: MATSUDA SHINZABURO
IPC: G05F1/455
Filed: 1987-10-29
Abstract: PURPOSE:To prevent a capacitor from being excessively charged and to remove the overshoot of a DC output voltage by reducing an AC voltage control reference at the time of turning off a control rectifier element to be turned on and off, and delaying the ignition phase of an AC thyristor switch. CONSTITUTION:When a DC side control rectifier element (GTO) 7 is turned off, an analog switch 20 is turned on and a voltage reference signal 12 goes a value V1-DELTAV obtained by adding the output voltage -DELTAV of a correcting voltage reference 18 to the output voltage v1 of a voltage reference generator 17. Thereby, the value of the signal 51 is reduced less than an AC output voltage signal 52, the ignition phase of the AC control thyristor switch 3 is delayed and the AC output voltage goes the V1-DELTAV. Thereby, excess current to the capacitor in a smoothing circuit 6 can be suppressed. When the GTO 7 is turned on, the switch 20 is turned off, the signal 51 is turned to the V1 again and the DC output voltage can be smoothly controlled without being overshot.

Title: Very high density recording system utilizing charged particle beam
Inventor: AIDA TOSHIYUKI
IPC: G11B9/10
Filed: 1986-11-19
Abstract: PURPOSE:To perform recording and reproduction with the same charged particle beam generating source, by drawing an ion beam while setting the potential of a traget to negative in polarity by using a liquid metal as a light emitting source for a charging beam, and drawing an electron beam setting the potential of the target at positive polarity. CONSTITUTION:A recording dot 5 is formed by projecting an Sn or Pb ion beam 3 on a track width 4 where a prescribed groove process is applied corresponding to digital information outputted from an information signal processor 2. The ion beam 3 is converged by an ion current, for example, at 0.1mumphi, and it is possible to perform dot write of 0.1mumphi on an Si plate 6 on which the track groove process of 0.2mum is applied. Next, at the time of reading, the charged particle beam generating source 1 is switched to the negative polarity, and the target to the positive polarity based on an input signal. In such way, it is possible to draw the electron beam of a required current value. Since no tailor cone shape of the liquid metal is changed even when receiving ion impulse, because generating source of electron is made of the liquid metal, current noise is reduced, and the service life of device can be extended.

Title: Electrophotographic printer
Inventor: NAGURA MAKOTO
IPC: G03G21/10
Filed: 1989-10-20
Abstract: PURPOSE:To automatically detect a toner recovery tank as being full and to eliminate the need of frequently discarding and replacing the toner recovery tank before it becomes fully by providing a means detecting the recovered toner being full on a toner supply quantity detector. CONSTITUTION:A toner supply requesting signal is outputted from a supplying toner tank contents detector 10 when a toner quantity in a toner supply tank 1 runs short, and the time for supplying toner can be known by the toner supply requesting signal from the supplying toner tank contents detector 10. On the other hand, since a toner quantity to be recovered is univocally determined from a supplied toner quantity, a toner quantity in the toner recovery tank 8 can be also known by the toner supply requesting signal from the supplying toner tank contents detector 10. Thus, without using the means exclusively used for detecting the recovered toner as being full, the toner recovery tank can be automatically detected as being full, and moreover, the toner tank does not need to be frequently discarded nor replaced before it becomes full.
