Abstract: A method of, apparatus for and computer-readable medium for obtaining a program for a distributed memory-type parallel computer by dividing data for a program written for a serial processing computer. The method comprises changing a declaration of an array to be subjected to indirect or irregular division which is designated by the mapping array in the program into a declaration of an allocation array; inserting statements to declare the allocation array for converting subscripts and to calculate the size of the divided array during processing, and inserting a statement to preserve or to release an area for divided arrays corresponding to the calculated length of arrays to be divided and subscript conversion arrays during processing.

Abstract: An on-vehicle audio system reproducing bodily-sensible sounds is devised to rapidly eliminate masking of bodily-acoustic audio sounds caused by vibrations of a running vehicle and generate bodily-sensible sounds without giving an inharmonious feeling to the listener. The system has a low pass filter for extracting only low frequency band components of an input signal, an amplifier for amplifying the output of the low pass filter and delivering the amplified signal, a vibration unit disposed in a seat of the vehicle for converting the amplified signal to mechanical vibrations. To eliminate the masking, the system is provided with a vibration sensor for generating a vibration signal of a magnitude in accordance with vibrations of the vehicle, and a level adjusting unit for adjusting the level of the input signal in accordance with an average level of the vibration signal.

Abstract: An antenna apparatus including a small loop antenna element fabricated by printed circuit method, a variable capacitor for matching the antenna element to broadcasting frequency and an amplifier for the received signal. The variable capacitor and the amplifier are mounted on a printed circuit board containing the loop antenna element and the variable capacitor is rotatably mounted on the board centrally of the loop antenna element. A second loop antenna element may be mounted either concentrically on the said side of the printed circuit board or on the other side of the board. A second variable capacitor cooperates with the second antenna element and a single manual element controls both capacitors.

Abstract: An electrostatic type electroacoustic transducer includes a stationary electrode having a rear electrode, a pair of electret films formed one at each side of the rear electrode, and a plurality of through holes. A pair of movable electrodes are each disposed, through a respective spacer, on the electret film bearing stationary electrode in a manner to confront the electret film. Acoustic signal voltage is supplied between the movable electrodes.
