摘要： A lens controls the chromatic aberration of an objective lens for practical use in an optical disk system. The lens has first and second aspherical surfaces each providing a positive refractive power for focusing a light through a transparent plate and satisfies a condition: ##EQU1## where f.sub.L =focal length of the lens, d.sub.c =thickness of the transparent plate, n.sub.c =refractive index of the transparent plate, .lambda.=center wavelength of the light, NA=numerical apperture of the lens, .nu..sub.L =local dispersion of the lens, and .nu..sub.c =local dispersion of the transparent plate. The local dispersion of each element is expressed by: ##EQU2## where n.sub.80 is refractive index at a center wavelength .lambda. nm, n.sub..lambda. +5 a refractive index at .lambda.+5 nm, and n.sub..lambda. -5 a refractive index at .lambda.-5 nm.

摘要： In order to accurately control the operation of the engine while still achieving near optimal swirl rate control, the swirl is controlled by a valve which is separate from the engine throttle valve and which is basically controlled in response to the pressure prevailing across the same. Various operating parameters such as the instant air-fuel ratio of the charge being combusted in the combustion chambers are utilized to modify prerecorded values to those which will induce the best setting for the valve.

摘要： A filter is disposed in the exhaust passage of an internal combustion engine in order to trap particles suspended in exhaust gas. A burner serves to burn off the particles deposited on the filter. Either the pressure in the exhaust passage at a point upstream of the filter or the pressure difference in the exhaust passage across the filter is selectively sensed. In place of sensing the pressure difference, the pressure in the exhaust passage at a point downstream of the filter may be sensed. The ratio between the upstream pressure and the pressure difference, or the ratio between the upstream pressure and downstream pressure is determined an as indication of the degree of clogging of the filter. The burner is operated on the basis of this ratio.

摘要： A projection television apparatus which has three monochromatic cathode-ray tubes, two type of dichroic mirrors, and a lens. Red, green and blue images from the three tubes are combined into the color image by the two types of dichroic mirrors and the resulting image is enlarged and projected on the screen by one lens. The two types of dichroic mirrors are crossed at a right angle in the shape of an "X". Each type of dichroic mirror is split in two through the line of intersection and the two parts of the respective dichroic mirrors of each type have different transmission characteristics, so that color shading is improved.

摘要： An engine system comprises an internal combustion engine and an exhaust gas treatment system, such as a three-way catalytic converter or an oxidation catalytic converter. The engine has an additional intake means, in addition to a main intake means for admitting by induction an air fuel mixture to a combustion chamber, for admitting under pressure above atmospheric pressure air to the combustion chambers during a period initiating during the exhaust stroke and terminating during the intake stroke for the purpose of expelling residual gas from the combustion chamber to bring about a stable combustion.
