Abstract: PURPOSE:To diminish the influence of malfunctions from a gas detecting device by providing a differentiating means, reliability detecting means, time calculating means, and operating time deciding means so as to improve the S/N, eliminate the malfunction of the device caused by the disturbance, etc., of air flows, improve the gas detecting speed of the device, and make the operating time of an air-conditioning device to be able to comform with the degree of air contamination. CONSTITUTION:A noise filter 14 prevents the malfunction of an air cleaner 10 by evaluating the degree of reliability of sensor signals and a comparator circuit 18 detects smoking from the output of a smoothing circuit 16. An second order differential filter 20 prevents the operation of the cleaner 10 when no smoking is made by detecting the noise of the cleaner 10 and differentiating the output of the circuit 16. When the conditions are met, a smoking detection circuit 22 actuates the cleaner 10 and a timer 24 fixes the operating time of the cleaner 10 and counts the time elapsed. A chattering preventing circuit 28 manages the operation of the cleaner 10 so that the cleaner 10 can be operated during the operating time decided by the timer 24 or another operating time decided by a stopping slice generation circuit 26, whichever shorter.

Abstract: PURPOSE:To obtain a shaped-beam antenna containing a primary radiator having a large degree of freedom with a simple constitution by consituting a main reflector with the envelope surface of a line group formed in accordance with the section form of a shaped beam to be synthesized. CONSTITUTION:A main reflector is formed by a part of five types of parabolas 3-7. These parabolas use the phase center point P of a primary radiator 13 as a common focal point and axes Z3-Z7 having different directions with angles theta3-theta7 on the basis of a reference axis Z of the reflector 2. With an antenna of such a consitution, the radio waves of a spherical wave source radiated within a cut plane from the radiator 13 are reflected by parabolas 3-7 and then radiated within the same plane as the radio waves traveling toward each axis. The radiation characteristics within the cut plane are shown by a solid line 40 as mainly a synthetic wave. Thus it is possible to synthesize the desirable radiation characteristics by adjusting the number of parabolas forming cut lines, the size of each parabola, the focal distance and the axis direction respectively.
