Title: Guitar
Inventor: FUROIDO DEII ROOZU
IPC: G10D3/12
Filed: 1989-04-20
Abstract: PURPOSE: To make it possible to immediately retune uncut strings when one of strings of a stringed instrument is cut off by providing a guitar with a height adjusting means for adjusting the height of a fixing member for a guitar body. CONSTITUTION: The height adjusting means 96 for controlling the height of the fixing member 90 for the guitar body is adjusted on a position where a tremolo base plate 24 is in a tuned state. If a string is cut off, the means 96 is arranged under the base plate 24 so as to be returned to the initial tuned neutral state and then the base plate 24 is lifted by operating the means 96 by a hand and uncut strings are retuned up to tuned state positions. Thereby even when one of strings is cut off in performance, uncut strings can be instantaneously retuned.

Filed: 1990-04-19
Abstract: PURPOSE:To remove a pulsating component by the heat exchange due to a resistor and to dispense with a smoothing condenser by making the voltage across both terminals of the Zener diode of a DC voltage stabilizing circuit constant. CONSTITUTION:A stabilizing circuit 4 consists of a resistor 8 and a Zener diode 9 connected in series and the Zener diode 9 is inversely biased by DC voltage ER and the amplitudes of induced voltages ea, eb, ec are appropriately set so that the voltage EO across both terminals of the Zener diode 9 is fixed to a predetermined value equal to Zener voltage even when a backward current I is changed by the pulsation of the DC voltage ER to make the amplitude of the DC voltage ER higher than the Zener voltage of the Zener diode 9. The current I flowing to the resistor 8 to become the backward current of the Zener diode 9 becomes I=(ER-EO)/R but this current 1 is pulsated and the amplitude of the DC voltage ER or the resistance value R of the resistor 8 is set so that the voltage EO across both terminals of the Zener diode 9 becomes constant Zener voltage even with respect to the pulsation of the current I. The current I is removed by the heat exchange due to the resistor 8 and no pulsation appears in the voltage EO across both terminals of the Zener diode 9.
