    Abstract: An active noise control system is capable of canceling out noise in the passenger compartment of a vehicle based on low-frequency road noise. The active noise control system has a feed-forward control unit for being supplied with reference signals highly correlated to noise from a noise source and generating a noise cancellation signal which is out of phase to noise in the passenger compartment of the vehicle, and a canceling sound generating unit disposed in the passenger compartment for generating a noise canceling sound in response to the noise cancellation signal from said feed-forward control unit. The active noise control system also has microphones for generating reference signals which are positioned respectively near the base of the front seat, near the center of a roof, and within a trunk compartment, i.e., respectively at vibrational antinodes of a primary or secondary acoustic normal mode of the passenger compartment in the longitudinal direction thereof. Output signals from the microphones are supplied as the reference signals.

    Abstract: A measurement method is provided, which enables to obtain a two-dimensional image with better quantitative-ability by suppressing the influence of the charge-up, when the two-dimensional secondary ion image is obtained for a biological material fixed on a substrate having a high resistivity by utilizing a TOF-SIMS method in a certain wide area. A two-dimensional image having considerably high positioning resolution-ability can be obtained by the procedure in which the pulsed primary ion beam is irradiated at a spot, and the pulse-wise spot-applications of the primary ion beam and the simultaneous detection of the secondary ion generated from the irradiated primary ion beam proceed along with a discontinuous scanning pattern, and eventually the results of these secondary ion measurements are reconstructed into a two-dimensional image in line with the aforementioned discontinuous scanning pattern.

    Abstract: The absorber for use in absorption chillers of the present invention comprises a plurality of cooling water pipes 2 extending horizontally in the interior of the absorber chamber. A plurality of flat heat transfer plates 1 are spaced apart from one another and arranged horizontally in a vertical position, and the plurality of cooling water pipes 2 extend through these heat transfer plates 1 perpendicular thereto. The pitch Pd of the plates 1 is 3 to 15 mm. Each heat transfer plate 1 is integrally formed on its upper end face with an absorbent receptacle 10 V-shaped in cross section and extending longitudinally of the upper end face. The bottom portion of the receptacle 10 is formed with two rows of absorbent holes 11 positioned upwardly of respective surfaces of the plate 1. The holes 11 of each row are spaced apart from one another longitudinally of the plate 1 and each have an outlet adjoining the surface of the plate 1. This enables an absorber to have a higher absorbing capacity than conventional absorbers.

    Abstract: In a noise suppressor, a noise signal detected by a first detector is inputted to an adaptive filter and a FIR filter. An output signal of the adaptive filter is reproduced by a speaker. The signal reproduced by the speaker and a noise signal from a noise source are detected by a second detector. The signal detected by the second detector is band-limited by a filter circuit and sent to a LMS computing circuit. The LMS computing circuit updates a coefficient of the adaptive filter so as to minimize an output signal of the filter circuit in response to an output signal of the FIR filter and an output signal of the filter circuit.
