Title: Key interface circuit
Inventor: SAEKI TAKASHI
IPC: G06F3/02
Filed: 1979-06-04
Abstract: PURPOSE: To make use of a key interface circuit for a push-button dial telephone set effectively while eliminating the need for clocks, by providing switching methods between bases of PNP and NPN transistors whose emitters and collectors are connected to two current supply parts and output parts.  
     CONSTITUTION: Between base terminals H 1  and H 2  of PNP transistor TRs11 and 12, and base termianls L 1  and L 2  of NPNTRs13 and 14, switch parts are interposed. When the switch between terminals H 1  and L 1  turns ON, a current flows from electric power terminal Vcc through resistance 15 by way of TR11, the switch, TR12, and earth terminal E to turn ON TRs11 and 12 and then TR18, and output terminals H10, H11 and L11 are all held at "L" correspondingly. Namely, the holding of terminal L11 at "L" makes it possible to find which lateral line offers information, and the holding of terminal H11 at "L" discriminates which lateral line (among longitudinal lines corresponding to terminal L11) offers the information. Further, an output obtained from common output terminal H10 is used for eletric power feed and control over an oscillating circuit for dial signal generation of a telephone set. Additionally, any clock pulses are not used unlike conventional one.

Title: Karaoke device
Inventor: MATSUMOTO SHUICHI
IPC: G10L17/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To make automatically switchable a conversion mode according to the kinds of music and the sex of a singer when voice conversion between the voices of man and woman is performed by comparing the judging result of a voice analyzing means with the sex of the vocal of the music and specifying the direction of the voice conversion according to the comparison result. SOLUTION: When a user instructs for a voice conversion mode in a KARAOKE performance, the input voice of a male single is analyzed by a voice analysis part 321 and its interval is compared with 1st and 2nd threshold values PH and PL. Here, when the input voice is a low-tone voice typical of a male, its interval is lower than the 2nd threshold value PL, so it is decided that the singer is a male. A parameter part 323 compares the sex decision results of both a sex decision part 322 and the voice analysis part 321 and from this comparison result, it is recognized that the man is singing the music of a female vocal. Consequently, the sex conversion mode from the man to the woman is specified to a voice change part 324.

Filed: 1986-03-31
Abstract: PURPOSE:To prevent a motor from heating and to save power consumption by providing an arrival detection means which detects that a moving body reaches a command position and outputs an arrival signal and a power supply stop means which inputs the arrival signal and stops a drive signal from being outputted to a motor. CONSTITUTION:When a measurement input voltage from an input signal terminal 1 is balanced with a divided voltage from a potentiometer 13 (a state t1), a deviation alpha calculated in a differential amplifier 3 comes to zero. Due to the zero deviation, an absolute value amplifier circuit 5 will not output a signal to a V/F conversion circuit 7. After a time tw passes since the zero deviation alpha, that is, the balanced state, a one-shot timer 17 never outputs an enable signal, whereby a drive circuit 9 stops the current to exciting coils phi1-phi4, and the heating of a pulse motor 11 can be prevented.
