    • A multi way speaker system comprises an amplifier, frequency dividing network including a plurality of filters, a plurality of speakers respectively responsive to the output signals of the filters, and a summing circuit responsive to the output signals of the filters for producing a composite signal to be fed back to the input of the amplifier to establish a negative feedback loop. Because of the feedback loop undesirable influences by various elements included in the filters are diminished and thus the speakers reproduce audio frequencies with high fidelity. At least one equalizer may be employed in the feedback loop, while auxiliary filters may be used in such a manner that the output terminals of the auxiliary filters are connected to only the summing circuit so that the output signals of the auxiliary filters are added to an output signal of at least one filter of the frequency dividing network. In order to supply the network with the output signal of the amplifier and to feed the composite signal back to the amplifier a three-wire coaxial cable may be used. The three-wire coaxial cable is used in such a manner that the composite signal flows through a conductor which is shielded by another conductor carrying the output signal of the amplifier. A switch and a resistor network may be used in the feedback loop for avoiding undesirable oscillation and output level variation.
    • 多路扬声器系统包括放大器,包括多个滤波器的分频网络,分别响应于滤波器的输出信号的多个扬声器,以及响应于滤波器的输出信号的求和电路,用于产生复合信号 反馈到放大器的输入以建立负反馈回路。 由于反馈回路,包括在滤波器中的各种元件的不期望的影响减小,因此扬声器以高保真度再现音频。 在反馈回路中可以采用至少一个均衡器,而辅助滤波器可以以这样的方式使用:辅助滤波器的输出端仅与求和电路连接,使得辅助滤波器的输出信号被加到 分频网络的至少一个滤波器的输出信号。 为了向网络提供放大器的输出信号,并将复合信号反馈给放大器,可以使用三线同轴电缆。 三线同轴电缆的使用方式是复合信号流过导体,导体由承载放大器输出信号的另一个导体屏蔽。 可以在反馈回路中使用开关和电阻网络,以避免不期望的振荡和输出电平变化。

    • A simple manufacturing method for an organic electroluminescent panel in which organic electroluminescent elements are arranged and sealed by a sealing adhesive. The electroluminescent panel has excellent sealing properties and excellent durability as a result of the organic electroluminescent elements being adhered to one another by a heat-curable adhesive. The manufacturing method is for an organic electroluminescent panel in which at least a first electrode, an organic functional layer containing a light-emitting layer, an organic electroluminescent element having a second electrode, and a sealing substrate are bonded together on a substrate by the heat-curable adhesive. The method includes forming a heat-curable adhesive layer on the sealing substrate, subjecting the heat-curable adhesive layer formed on the sealing substrate to pre-heating treatment, bonding the pre-heated heat-curable adhesive layer to the organic electroluminescent element, and subjecting the heat-curable adhesive layer to heat curing, in the given order.

    • Disclosed are a coating method of forming a coating with a stable thickness from a coating solution with a low viscosity employing a slit-type die coater and an organic electroluminescence element prepared employing the coating method. The coating method employing a slit-type die coater comprises the steps of allowing a lip tip of the slit-type die coater to bring close to the substrate to form a coating solution bead between the lip tip and the substrate, and coating on the substrate a coating solution ejected from a slit outlet at the lip tip while relatively moving the slit-type die coater and the substrate, thereby forming at least two coating layers in the stripe shape, featured in that the lip tip has at least one groove in the coating region in the coating width direction, and a pressure at the slit outlet of the coating solution of the bead is negative or zero.
