Title: Carrier recovery in dab receivers
Inventor: KATSUMOTO HIROSHI
IPC: H04J11/00
Filed: 1998-05-12
Granted: 2003-01-07
Abstract: A receiver is provided which can perform normal reception even under strict environments such as multi-path environments. A frequency offset detector (7) detects a frequency offset amount in accordance with a phase reference symbol.  The detected frequency offset value is integrated by an integrator (17). The integrated value is compared by a comparator (18) with a predetermined threshold value range. If the integrated value output from the integrator is in the threshold value range, a frequency offset value amount detected by another frequency offset detector (8) in accordance with a phase difference of a delay-detection output is selected by a switch circuit (10). If the integrated value is not in the threshold value range, the frequency offset value detected by the frequency offset detector (7) is selected by the switch circuit (10). In accordance with each selected frequency offset value, automatic frequency control of the receiver is performed.

Abstract: A toy for launching ring airfoils comprises a member (58), a ring airfoil support (60) mounted on the member, and a propelling element (62) for moving the support along the member from a first to a second position. The ring airfoil moves with the ring airfoil support as the ring airfoil support moves as the support decelerates at the second position, the ring airfoil is launched forward. The member may include a helical channel (68) which receives a pin (78) attached to the support to impart spin to the support and ring airfoil. The toy may include a protective housing (32), a return element (34) to move the support to a launch-ready position, and a trigger (106) to release the support for forward movement. Components of the toy are designed so that the characteristics of the ring airfoil are within certain safety limitations.

Abstract: This invention relates to a process for producing a lactose-free milk which does not confer a sweet taste to the milk normally resulting from the hydrolysis of lactose into monosaccharides. The process comprises the step of reducing the lactose content of the milk to about 3 % prior to hydrolysis with lactase. When the milk is skimmed milk, the protein content may be increased to about 3.8-4.0 % or greater, which further improves the organoleptic properties of the milk. Milk so processed and dairy products derived therefrom are also disclosed and claimed.

Abstract: To transmit an actual sound (noise) when the noise level becomes higher than a regulation standard.      In each noise detecting unit 1, the level of noise is measured through a microphone 5 and a noise meter 6 and input into a radio set 7. At the same time, an actual sound as the noise is input through a microphone 8 and a microphone amplifier 9 into a PHS 10. In a noise monitoring unit 2, a PC 14 communicates with the radio set 7 in each noise detecting unit 1 through a radio set 13 to input the noise level measured by each noise detecting unit 1. The PC 14 determines whether or not the noise level is higher than a regulation standard. If the noise level is higher than the regulation standard, the PC 14 requests a PHS 15 to call the PHS 10 in the specified noise detecting unit 1 to establish the communication between the PHS 15 and the PHS 10. At this time, a maintenance worker 4 can hear the actual sound from the PHS 15. Further, the actual sound is recorded by an MD recorder 16.

Abstract: An acoustic jet disposed within an aerodynamic surface (9), such as a wing or a blade, has a resilient wall (16) supporting a mass (17). Vibrations of the blade cause oscillatory pressure waves within the acoustic jet, the nozzle (20) of which directs fluid particles having high momentum flux essentially tangentially into the boundary layer of the suction surface (22) of the blade, the resonant cavity of the synthetic jet being replenished with particles having low momentum flux drawn from the flow in a direction normal to the surface, thereby to provide a net time averaged flow of fluid particles of increasing momentum flux into the boundary layer to defer or prevent the onset of boundary layer separation. Single and double chambers drive nozzles separated streamwise or spanwise on airfoils (blades, wings) and fuselages. Applications include helicopters, airplanes, air moving machines and wind energy electric power generators.

On commence par déterminer un premier niveau de puissance de sortie associé à la transmission simultanée d'un premier ensemble d'un ou de plusieurs courants de trafic entre la station de base et les stations mobiles sur la liaison aval. On compare ensuite ce premier niveau de puissance de sortie au plafond de puissance maxi. Cette comparaison permet d'identifier dans la liaison aval au moins une trame de temps de capacité suffisante pour la transmission d'au moins un courant de trafic supplémentaire. On transmet ensuite simultanément le premier ensemble de courants de trafic et une partie d'au moins un courant de trafic supplémentaire pendant au moins une trame de temps sur la liaison aval.
