Title: Device and method for generating musical sound
Inventor: SUZUKI TAKASHI
IPC: G10H1/06
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To decide an independent tone color without depending on a pitch by changing an occurrence speed of a generated impulse response signal itself according to a tone color decision factor different from a pitch decision factor independently of a repeated period. SOLUTION: Respective impulse response signals of an impulse signal storage part 51 are read out from an impulse signal read-out part 53 by the low-order read-out address data R1, R2. The now-order read-out address data R1, R2 are incremented at a speed according to musical sound factor information except pitch information. Then, a read-out speed isn't decided by the pitch information. The impulse response signals are read out repeatedly, and the repeated period is changed according to the pitch information, and the repeated period and the read-out speed are decided independently of each other. Further, when the musical sound factor information is changed at every musical sound or while uttering, the high-order read-out address data are switched, and the read out impulse response signal is switched also.

Abstract: PURPOSE: To reproduce a sound field close to that of a natural sound by reproduction of rich low frequency sound and ultralow frequency sound by providing a main sound reproducing device for reproducing sound waves, a sub sound device for causing interference phenomenon and side walls for causing the interference more effectively. CONSTITUTION: A main sound reproducing device 1 may be of a cone type or a flat type and a sub sound reproducing device 2 reproduces a sound wave for interference and may be of a cone type or a flat type similarly to the case with the device 1. Then side walls 3 are provided to prevent diffusion of spatial sound wave causing interference. Then a sound blank state i formed at the rear of the main sound reproducing device 1 by the interference effect by the sound wave generated by the sub sound reproducing device 2 to remarkably reduce a driving force load. As a result, a surplus driving force is concentrated to the front side thereby increasing the amplitude of the sound wave. Thus, a sound field close to that of a natural sound is reproduced by reproducing rich low frequency sound and ultralow frequency sound.

Title: Image forming device
Inventor: WATABE NOBUYUKI
IPC: B41J2/13
Filed: 1986-11-29
Abstract: PURPOSE:To protect a head from troubles in an ejection ON signal generating circuit or a transmission system, a malfunction of a nozzle or the like, by providing a waveform shaping circuit at a stage immediately preceding a recording head. CONSTITUTION:Signals except an ENABLE signal are inputted directly from a buffer 103 to a BJ head 105, whereas the ENABLE signal is inputted to the head 105 after being accurately shaped to have a predetermined pulse duration (e.g., 10musec) by a waveform shaping circuit 104. The ENABLE signal is a signal for determining the period of time for which heaters are actually turned ON. Therefore, the ENABLE signal is turned ON while both output signals from shift registers 106a-106d and output signals from latches 107a-107d are ON, for a period of time for energization of the heaters, whereby heater drivers 109a-109d are turned ON, and the heaters are energized, thereby ejecting an ink. If the ON time TON of the ENABLE signal is maintained at an accurate value, breakage of the heaters or failure in ejection would be caused.

IPC: H01L41/09
Filed: 1990-10-26
Abstract: PURPOSE:To actively control vibration through nonlubricated simple structure by giving vibration to a spring to support a bearing, severally sticking piezo-elec tric ceramics plates to both the sides of the spring to form electrodes on the surfaces of the above plate, and connecting the electrodes to a resistance to form a circuit for converting the vibration into electricity. CONSTITUTION:A plate spring 3 is given vibration through a bearing 2 to support a rotary shaft 1, and piezo-electric ceramics plates 5 are severally stuck to both the faces of a square section-shaped rib 4 composing the spring 3. An electrode is formed on the surface of the plate 5, and as the one side of the plate 5 elongates, its opposite side contracts to make piezo electric effect generate positive and negative voltages in the electrodes on the plate 5 according to the elongation and contraction of the plate 5. Potential difference therefore occurs between the two electrodes to flow electric current through a resistance 6 connected between the electrodes to generate heat in the resistance 6. Thus vibrational energy is converted into electrical energy and then thermal energy to generate damping effect for producing a nonlubricated damper bearing.
