Patent JP-H0451295-A (JP)
Title: Timbre controller
Inventor: HATANAKA MASAHIKO
IPC: G10H7/08
Filed: 1990-06-19
Abstract: PURPOSE:To obtain an output waveform signal which includes a higher harmonic spectrum by outputting a waveform signal which is inputted to a filter part in order, converting the amplitude of a feedback signal by a waveform conversion part in a feedback loop, and controlling the feedback quantity by a feedback quantity control part. CONSTITUTION:When the input waveform signal alpha of a musical sound, etc., is inputted to a filter part 11 first, an adder 12 adds the input waveform signal alpha which is inputted in order to a feedback signal (d) and sends the result out to a delay part 13 in order. Then the delay part 13 delays the addition result which is inputted in order by a time longer than one sample clock and then outputs the result as an output waveform signal beta in order. The waveform signal which is outputted from the delay part 13, on the other hand, is sent out as a feedback signal (e) to the feedback quantity control part 14 as well. The feedback quantity control part 14 multiplies the feedback signal (e) which is inputted in order and a feedback quantity indication signal which is outputted from a feedback quantity indication part 41 by a multiplier 42 and sends the result as a feedback signal (c) to the waveform conversion part 83 in order. The feedback signal (d) is added by the adder 12 to the input waveform signal alpha which is inputted in order and the result is sent out to the delay part 13 again.

Abstract: PURPOSE:To provide a semiconductor device which has excellent high frequency characteristics by covering an insulating film with a polycrystalline or amorphous silicon film, then emitting a laser to convert it to a single crystal, and providing a p-n junction. CONSTITUTION:After an n<+> type layer 25 is formed on a surface region of a p-type silicon substrate 11, an n-type single crystal silicon layer 14 is formed by laser anneal epitaxy, with an SiO2 film 26 as a mask as impurity is diffused in the layer 14 to form a p-type diffused layer 27 to become a base. Then, an emitter 29 of a low resistance n<+> type region, a low resistance n<+> type layer 30 for leading a collector electrode and electrodes 31-34 of aluminum are formed by ordinary bipolar steps. Since the p-type single crystal silicon layer formed by emitting a laser of an element thus formed in this manner is led as the leading electrode of the base 27 on an SiO2 film 12, a parasitic capacity between the base and the collector is reduced to provide excellent high frequency characteristics and to decrease the size of the element.
