Abstract: The invention presents means for applying negative feedback more powerfully and stably than before over a frequency range as wide as possible, in the constitution for detecting a reproduced sound of a speaker used in various acoustic appliances by a microphone, and applying a negative feedback to an input signal of the speaker by the detected signal, and correcting the reproduced signal by improving the reproduction frequency characteristic and other characteristic of the speaker. 
     A fundamental constitution of an acoustic reproducing apparatus of the invention comprises a subtractor having an input terminal, a power amplifier for amplifying the output signal of this subtractor, a speaker for reproducing the output signal of the power amplifier, a microphone for detecting the acoustic output signal radiated from the speaker, a microphone amplifier for amplifying the acoustic output signal detected by the microphone, and an adder/subtractor for adding or subtracting the output signal of the microphone amplifier and the input signal of the power amplifier, wherein the output signal of the adder/subtractor is connected to the subtractor to compose a negative feedback circuit. 
     Or, in an acoustic reproducing circuit using a speaker box incorporating a passive radiator, a microphone is disposed in the front side of the magnetic circuit of the speaker for reproducing the output signal of the power amplifier or speaker rear enclosed acoustic space, or in the enclosed acoustic space with the passive radiator of the speaker front side, and the output signal of the microphone is added or subtracted with the input signal of the power amplifier in the adder/subtractor in the fundamental constitution above, and the signal is subtracted from the input signal in the subtractor, thereby composing a negative feedback circuit.

Abstract: An antenna system comprises a main antenna (11) for use of transmission and reception and a dedicated sub-antenna for use of reception. The antenna beam of the antenna system is scanned in the direction of a beam width to be compressed. Both received signals of the main antenna and the sub-antenna are fed to a signal processing circuit (14) and a multiplying circuit (14), and converted to power signals and then multiplied by each other. In this processing, only if the cosine value corresponding to the phase difference between the received power signals of the main antenna and the sub-antenna is positive, is the multiplication between the received power signals carried out and the result further multiplied by the cosine value. The obtained signal is then output as a final output signal.

Abstract: Method and apparatus for selectively controlling interrupt latency in a data processing system (10). In one embodiment, the present invention uses an interrupt control register bit field (50) to determine whether or not execution of an instruction may be interrupted by an interrupt request before execution of the instruction has completed. In some embodiments of the present invention, a first set of instruction may be interrupted mid-execution, while a second set of instructions always complete execution. Which instructions belong to the first set of instructions may be user programmable (e.g. by register bit field 52) or may be fixed. It is advantageous in some data processing systems (10) to define the instructions having the longest execution times as being part of the first set of instructions in order to reduce interrupt latency.

Abstract: A control system of a vehicle automatic transmission. An engine load and a vehicle speed are detected and based on them, a vehicle acceleration to be obtained from the detected engine load and vehicle speed is determined in accordance with the preestablished characteristics. An actual vehicle acceleration is at the same time calculated in response to the detected vehicle speed. The difference therebetween is then calculated and the calculated value is added to a difference calculated earlier to obtain an average therebetween. Five gear shift scheduling maps, for example one for moderate hill climbing, one for level-road running, one for steep hill descent, are preestablished and in response to the average obtained, one of the maps is selected. A gear shifting is controlled based on the selected map. In a specific condition such as the engine load changes abruptly, braking is in progress and so on, the map selection is suspended and the control is carried out using the map selected earlier.
