Title: Sound synthesizing method and apparatus
Inventor: SUDA NORIO
IPC: G10L25/00
Filed: 1988-04-14
Abstract: A sound synthesizing method and apparatus for producing synthesized sounds having a property similar to the property of natural sounds emitted from a natural acoustic tube having a variable cross-sectional area. The natural acoustic tube is replaced by a series connection of a plurality of acoustic tubes each having a variable cross-sectional area. The acoustic tube series connection is replaced by an equivalent electric circuit connected between a power source circuit and a sound radiation circuit. The equivalent electric circuit includes a parallel connection of first and second electric circuits equivalent for adjacent first and second acoustic tubes of the acoustic tube series connection. The first electric circuit includes input and output side sections each including a propagated current source and a surge impedance element having a surge impedance inversely proportional to the cross-sectional area of the first acoustic tube. The second electric circuit includes input and output side sections each including a propagated current source and a surge impedance element having a surge impedance inversely proportional to the cross-sectional area of the second acoustic tube. A value for the current flowing in the radiation circuit is calculated to produce a synthesized sound component corresponding to the calculated value. Thereafter, similar calculations are repeated at uniform time intervals to produce a synthesized sound.

IPC: H04B1/68
Filed: 1985-05-30
Abstract: In transparent tone-in band (TTIB) systems the transmitter and receiver may include complementary circuits, such as modems, which require reference signals in order to operate. This problem can be solved by using those circuits in the transmitter (a mixer 63, and oscillators 33 and 36), which determine the width of the notch in the TTIB spectrum, to derive the reference signal. Thus the output signal of the mixer 63 is passed to a multiplier 64 and used as the reference signal for a transmit modem 62. In the receiver the required reference signal is derived from circuits whose output can be used to derive a signal dependent on notch width; for example the oscillators 38 and 43 and the mixer 66. Thus the output signal of the mixer 66 is passed by way of a phase shift circuit 67 to a multiplier 68 and used as the reference signal for the modem 65.

Abstract: Hitherto, roof and wall constructions with aluminium plates have been realised by mounting the latter on steel holders. In the event of a fire, the steel holder shields the aluminium panel from the heat. The load-bearing capacity of the roof or wall construction in the event of a fire is to be improved and the occurrence of high temperatures prevented. For this purpose, the load-bearing sections (5, 6) of the panel are produced from a more temperature-stable material than the space- filling sections (7). For example, the load-bearing sections are composed of steel, high-grade steel or a high temperature-resistant aluminium alloy and the space-filling parts are composed of high-grade aluminium or another conventional aluminium alloy. The panels can be employed for roof constructions preferably using trapezoidal load-bearing profiles. <IMAGE>

Abstract: In the construction of the sensor as a frame transfer sensor (FT) a control circuit therefor may not only be utilized for the information transfer and the electronic shutter, but also for a third purpose, namely for a reduction of the smear before integration. Starting from the control circuit for an information frame transfer (φ A , TG, φ B ), a parallel information shift (φ B , TG) and a serial information shift (φ C ) at the sensor and the electronic shutter (ESPS, BUF, MF, φ A ) at a pick-up member (PP) of the sensor (FT), the smear reduction is obtained by the use of a pulse generator (JC, FF, AN,I) at the electronic shutter, which generator is adapted to supply a series of reset pulses (ESPS) with a minimum number. A minimum number of two line-­frequency pulses occurring in line blanking periods has been given as an example.

Abstract: The floating gates of floating-gate transistors of a non-volatile memory are self-aligned by producing, on a silicon substrate (1), a gate oxide layer (2) overlaid successively with a polysilicon layer (3) which is subsequently lightly oxidised (13), and itself overlaid with a silicon nitride layer (4). Silicon nitride lands (5) are defined corresponding to the sites of the floating gates of the transistors. After definition and reactive plasma etching, a second finer nitride layer (14) is deposited. This second layer is then removed by full field plasma etching. It is shown that spacers (17, 18) are thereby left which protect the sides (15, 16) of the lands. A thick insulating oxide (6) is then grown between the lands. It is shown that the width edges of the conduction channels of the transistors are thereby simply aligned with the bird-beak ends of the thick oxide regions. <IMAGE>

Abstract: Radiolentille (10) ayant quatre ouvertures (12, 14, 16, et 18) de réseau piloté en phase positionnées de manière à assurer une couverture hémisphérique. Un agencement de compensateurs de phase (52) dont chacun est interconnecté avec quatre éléments (54, 56, 58 et 60) radiants, un sur chacune des quatre ouvertures. Un cornet d'alimentation (30) est utilisé pour alimenter la lentille, et des commutateurs (48, 50) dans la lentille sont utilisés pour commuter l'énergie reçue du cornet d'alimentation vers les compensateurs de phase, et après compensation de phase, vers une ouverture sélectionnée afin de rayonner. Les commutateurs jouent également un rôle en commutant l'énergie reçue d'une ouverture compensateur de phase et ensuite au cornet d'alimentation. Dans un autre mode de réalisation, le montage de composants transmetteurs et récepteurs, tel qu'un amplificateur (70) de haute puissance et un amplificateur à faible bruit (72), avec une combinaison de commutateurs inverseurs bipolaires et bidirectionnels dans la lentille est divulgué et débouche sur un réseeau d'antenne de type à semi-conducteur transmetteur-récepteur. Dans un mode de réalisation, les commutateurs permettent à la lentille de rayonner à partir de trois des ouvertures, pour un angle de balayage de 270 degrés à partir d'un seul cornet d'alimentation. L'adjonction par face d'autres cornets d'alimentation produit des faisceaux radiant multiples à partir d'une face.

Abstract: Circuit de commande de régime de moteur détectant la force électromotrice (FEM) de retour moyenne comme une mesure de régime du moteur. La FEM de retour charge un circuit (cf) condensateur lequel accumule la charge et développe une tension indicative de la vitesse du moteur. On peut utiliser un circuit d'échantillonnage et de maintien (134) pour échantillonner la FEM de retour lorsque le moteur (110) est mis hors circuit pendant chaque cycle. Cette tension est comparée à une tension de référence indicative du régime désiré du moteur. Un signal d'erreur est produit par comparaison du régime désiré avec le régime réel, et ce signal d'erreur est utilisé pour produire une série d'impulsions de périodes de fonctionnement variable, laquelle déclenche la mise en circuit et hors circuit du transistor (12) de commande de puissance, afin de commander le régime du moteur. Un circuit survolteur (48, 36; 164) à porte logique ou à porte SCR agit de manière synchronisée avec le train d'impulsions de déclenchement, pour activer le transistor (12) de puissance jusqu'à saturation élevée. Ceci diminue la résistance du transistor de puissance (12), provoquant moins de dissipation d'énergie à titre de chaleur perdue. Le circuit de commande de régime du moteur produit une famille de courbes de régime de couple, maintenant ainsi un régime constant jusqu'à ce qu'un point de flexion soit atteint, après quoi le régime chute en fonction inverse du couple. Un circuit (146) de commande de couple contrôle le courant du moteur, et maintient ce courant à un niveau sélectionné par l'utilisateur, afin de régler ainsi un couple de sortie désiré.

Abstract: An apparatus of the type defined above is provided with a refrigerating device for the refrigeration of the cream. A pump disposed within the refrigerated compartment of the apparatus is operable in a controlled manner to simultan­eously aspirate liquid cream from a respective container and air from the interior of the compartment, and to supply the thus formed mixture to a mixer device which supplies the finished whipped cream to a selectively openable dispenser of the apparatus. The mixing operation resulting in the finished whipped cream may be explained by the continuous subdivision, expansion and agitation of the mixture, resulting in the gaseous phase, namely, air, of the mixture supplied to the mixer device being dispersed in the liquid phase, namely, cream, with a considerable increase of the volume of the latter. The stability of this mixture, which is dispensed as whipped cream, is due to the formation of a protective pellicle of the protein contained in the liquid phase about each bubble of the gaseous phase dispersed therein. An apparatus of the type described above is generally known and will be understood by those skilled in the art without any further detailed description. Accord­ing to the invention, an apparatus of this type is provided with oscillating agitator means projecting into the liquid cream to act as a level sensor and operable to homogenize the temperature and the composition of the cream to thereby ensure its preservation and improve the quality of the dispensed product.
