Title: Electronic musical instrument
Inventor: TERANISHI KOICHI
IPC: G10H1/057
Filed: 1994-07-25
Abstract: PURPOSE:To provide an electronic musical instrument in which a legato performance is automatically simulated by providing an interval measuring means and a level control means. CONSTITUTION:Prescribed time interval data A are beforehand set to discriminate whether a legato performance is to be simulated or not. For a normal performance condition i.e., [key on time interval T > a prescribed value A] envelopes of the sounds of musical instruments and breathing have respective levels and shapes and breathing sounds are outputted only at the time of the start of sounds (key on). When the hitting key interval of a keyboard is played shorter than the value A, the breathing sound envelope becomes smaller. Since the envelope of a musical instrument sound is a same level, the outputted musical sound signals have less conspicuous gaps between sounds and signals of musical sounds, in which sounds are continuous and only high pitch sounds are varied, i.e., legato performance musical sound signals are generated.

Title: Horizontal deflection amplitude modulation circuit
Inventor: KASHIWAGI SHIGERU
IPC: H04N3/23
Filed: 1984-09-14
Abstract: PURPOSE:To attain the accurate modulation of a horizontal deflection amplitude by producing a sawtooth wave current which is flowed to a horizontal deflection coil so that the amplitude of said sawtooth wave current in response to the shape of a reference waveform and therefore compensating a phase delay due to the nonlinearity of a transistor or a circuit element. CONSTITUTION:A harmonic wave detecting circuit 8 delivers a voltage equivalent to the modulated wave parabolic component of the sawtooth wave current which is flowed to a horizontal deflection coil. An operational amplifier 9 serving as a comparator compares a reference voltage obtained from a waveform shaping circuit 7 with a detection voltage obtained from the circuit 8 and applies an output voltage V0 to a horizontal amplitude modulation circuit 5 for horizontal deflection coil current IH. Thus the voltage V0 of the amplifier 9 is set automatically so as to secure the coincidence at all times between a parabolic voltage W1 obtained in proportion to the parabolic modulated wave component of the current IH and the reference parabolic voltage W2 set previously. Thus the circuit 5 modulates the horizontal amplitude.

Namely, the notch part 14 is formed around the application position of conduction adhesive 13. Thus, conduction adhesive 13 flows into the notch part 14 with such constitution and therefore arrival to the metallic ring is inhibited and the size of the container main body is not changed.

Title: Synchronous generator
Inventor: KARERU HOORUDEN
IPC: H02K21/14
Filed: 1988-08-03
Abstract: PURPOSE: To prevent occurrence of a momentary disturbance in an apparatus due to a defect in a control relay by providing a centrifugal voltage regulator for sustaining the voltage of an induced current at a constant level by finely adjusting means for sliding a rotor to the outside of a stator. CONSTITUTION: When the rotational speed of a shaft 4 and a rotor 10 increases, the arm 26 and the weight 27 of a centrifugal voltage regulator 22 open outward around a spindle through action of centrifugal force. Consequently, the pressure being applied by the cam end part 28 of the arm 26 against a thrust plate 14 is increased thus increasing the pressure against a compression spring 13. Since the rotor 10 slides to the outside of a stator 5 as the compression spring 13 is compressed, the distance between the rotor 10 and the stator 5 increases and the voltage of an induced current lowers. More specifically, the centrifugal voltage regulator 22 ensures to sustain the voltage of induced current at a constant level for different speeds and current consumption of the shaft 4 and the rotor 10.
