Abstract: A intake system for a multiple-cylinder engine having a plurality of cylinders has a common intake passage (7) open to the atmosphere at its upstream end, a plurality of discrete intake passages (10a-f) which communicate the respective cylinders with the common intake passage by way of intake ports, and a circular passage (6) which is communicated with the cylinders and is adapted to propagate pressure waves generated by the intake strokes without reflecting the pressure waves. A part (6c) of the circular passage (6) which does not form a part of the intake air path through which intake air is introduced into the cylinders is smaller in cross-section (52) than a part (6a, 6b) of the circular passage (6) which forms a part of the intake air path.

Abstract: Self-blasting switches, with blasting produced by the arc, have a gas storage chamber in which the expanded gas is compressed and out of which it flows back to the extinguishing path when the current is approaching the point where it passes through zero, and hence blasts the arc. In the gas storage chamber, mixing takes place between the hot and the cold insulating gas, resulting in a reduction in the extinguishing characteristics. This disadvantageous mixing of the hot and cold extinguishing gas is avoided by the insertion of an intermediate wall 8 into the gas storage chamber 7 which separates the inflowing hot extinguishing gas from the cold extinguishing gas which is to be compressed and used for the extinguishing process. <IMAGE>

Abstract: A learning pattern is classified into a plurality of patterns by a classifying means (102). The result of the classification, as well as the representative features quantity calculated by a representative feature quantity operating unit (103), are stored in a dictionary storing unit (104) in respective regions. Upon recognition, after feature quantities of unknown input patterns are extracted from a feature quantity extracting unit (101), a a similarity operating unit (105) arithmetically operates the similarity between the input pattern and respective learning patterns for respective regions. The point accumulating means (106) searches a dictionary storing unit (104) and accumulates points corresponding to a rank for respective learning patterns included in class having the upper rank from the highest to a lower similarity for respective regions. The recognition result candidate outputting unit (107) outputs the recognition result candidate in accordance with the order of the higher accumulated point for the learning pattern. Therefore, the present pattern recognition can decrease the memory capacity of the dictionary and the number of the calculations.

Abstract: A frequency modulator is formed in a monolithic integrated circuit as a whole. A direct current signal from a center frequency control circuit and an alternating current signal from a voltage controlled amplifier (VCA) which receives a modulation signal and outputs the alternating current signal are applied to a control input of a voltage controlled oscillator (VCO). A center frequency (Fo) of the VCO is determined by the direct current signal from the center frequency control circuit and a frequency deviation amount (Δ f) of the VCO is determined by the alternating current signal from the VCA, and therefore, a frequency-modulated signal of Fo + Δ f can be outputted from the VCO. The direct current signal from the center frequency control circuit is also applied to a control input of the VCA, and therefore, the center frequency of the VCO as well as an amplitude of the alternating current signal, that is, the frequency deviation amount can be controlled by only the direct current signal.
