    • An apparatus includes: an affine transformer that subjects input complex IF signals I(t) and Q(t) to affine transformation according to affine transformation coefficients, and outputs compensated signals a(t) and b(t); a quadrature modulator that applies quadrature modulation on a local oscillation signal according to the compensated signals, and outputs a modulated signal (RF transmission signal); a quadrature wave detector that removes a carrier component from the modulated signal and outputs complex feedback signals I′(t) and Q′(t); and a control portion that extracts linear distortions remaining in the complex feedback signals I′(t) and Q′(t) as plural distortion coefficients (DC offsets of the I-phase and the Q-phase, an IQ gain ratio, and a deviation in orthogonality), and updates the current affine transformation coefficients in accordance with updating equations including the distortion coefficients to set updated affine transformation coefficients again in the affine transformation portion.

    • A dental attachment is disclosed which provides an improved connection force and fitting between an implant and a keeper. A keeper has a main body with a attracted face, a screw part that is located at the back face, a conical tapered shaft, and a projecting ring part. The projecting ring part has an inclining inner face and an acute angle pointed end. An implant has a screw hole part, a conical tapered hole part which has about the same inclining angle of the tapered axle part, and an inclining end face. When the keeper and the implant are connected, the tapered shaft and the tapered hole part are fitted closely and at the same time, the inner face of the acute angle pointed end and the inclining end part are in contact and at least the acute angle pointed end of the projecting ring part is elastically transformed toward the diameter.

    • A liquid fuel combustion apparatus for evaporating and vaporizing kerosene, gas oil or like liquid fuel by heating, admixing air with the vaporized fuel in a specified ratio and burning the resulting gaseous mixture in a combustion unit. The vaporizer for the liquid fuel comprises a liquid fuel drawing-up member (15) made of a heat-resistant porous body (8) or heat-resistant inorganic fiber fabric (9) for drawing up the liquid fuel, and a heat generating member (6) including coating layers (22, 23) of heat-resistant metal, heat-resistant alloy or heat-resistant metallic oxide for giving heat to the drawing-up member. To prevent formation of tar-like substances, a catalyst is preferably deposited on the surface of the drawing-up member and/or on the surface of the heat generating member. Further preferably, the outer periphery of the heat generating member (6) is in contact with the drawing-up member (5). The apparatus assures stable combustion over a prolonged period of time and is useful as a heater, kitchen range or the like.
