    摘要： Photoresist compositions, which can attain high-accuracy etching without causing separation and flexible printed wiring boards prepared with the photoresist compositions are disclosed. In order to etch a polyimide precursor layer on a conductive circuit, a photoresist composition comprising a photopolymerizable organic material (A), a water-soluble resin (B) and an amino-group-containing resin (C) is applied on the surface of the polyimide precursor layer to form a photoresist layer. Then, the photoresist layer is patterned by a photolithographic process. The polyimide precursor layer is etched and the pattern of the photoresist layer is transferred to the polyimide precursor layer. The amino-group-containing resin (C) in the photoresist layer is combined with an acid anhydride in the polyimide precursor layer to attain good adhesion and high-accuracy etching without causing separation of the photoresist layer. Alternatively, a film can be formed from the photoresist composition and then be applied on the surface of the polyimide precursor layer to form a photoresist layer.

    摘要： A secondary heat exchanger B for recovering latent heat from combustion gas includes water tubes 5 each of which is so inclined that a first end 50a is positioned lower than a second end 50b. Therefore, in draining water from each of the water tubes 5, water can be caused to flow smoothly into a water-inflow and hot-water-outflow header 6A connected to the first ends 50a. The secondary heat exchanger B includes a casing 7 which includes an upper wall 70a and a bottom wall 70b which are so inclined that the inner surfaces thereof extend generally in parallel with the water tubes 5, and the upper and the lower gaps 79a and 79b have constant widths s2 and s3. Therefore, the amount of heat recovery from the combustion gas passing through the gaps 79a and 79b can be increased.

    摘要： At a transmitting end, first and second dipole antennas are crossed each other by right angles and are arranged in a plane perpendicular to a propagating direction of radio wave. In first and second balanced modulators, a carrier signal is modulated with respective modulation signals having a phase difference of 90.degree. to produce balanced-modulated signals, which are then supplied to the first and second dipole antennas, respectively. Then a plane of polarization of a composite vector of radio waves transmitted by the dipole antennas is rotated at a frequency of the modulation signals, said frequency being higher than a fading frequency. The modulation signals are controlled by a state of a digital signal to be transmitted. At a receiving end, the digital signal is reproduced by receiving the transmitted radio wave by a conventional single side band receiver.
