    • An optical information memory medium comprising a substrate, an improved underlying layer formed on the substrate surface, and a recording layer formed on the underlying layer and mainly consisting of an organic pigment is disclosed. In this optical information memory medium, the underlying layer is formed by causing a compound containing a hydroxyl or carboxyl group selected from the group consisting of a radical polymerizable monomer containing a hydroxyl or carboxyl group, a copolymer obtained from a monomer containing a hydroxyl or carboxyl group, and a polymer compound containing a hydroxyl or carboxyl group to react with a hydrolyzed condensate which is derived from an alkoxide or an aryloxide of a metal selected from the group consisting of Al, Ti, Zr, In, Zn, Mg, Ni, and Cu or from a chelate compound mainly consisting of the metal. An underlying layer formed of a hydrolyzed condensate which is derived from the alkoxide or the aryloxide of a metal selected from the group consisting of Al, Ti, Zr, In, Zn, Mg, Ni, and Cu is also disclosed.

    • When SAW filter is used as a receiving filter of an antenna duplexer filter in a cellular radio equipment, since a transmitting signal of an out-band frequency has a large power for the SAW filter, the large power can leak into the SAW filter to generate inter-modulation disturbances in the SAW filter. Since the inter-modulation disturbances are generated when the transmission power density of the surface acoustic wave is made too large, input converters are divided, and the divided converters are disposed in the direction perpendicular to the propagation direction of the surface acoustic wave to lower the transmission power density. Since the divided converters are connected in series, reduction in the impedence together with increase of the aperture length can be compensated.
    • 当在蜂窝无线电设备中使用SAW滤波器作为天线双工器滤波器的接收滤波器时,由于带外频率的发射信号对SAW滤波器具有较大的功率,因此大功率可能泄漏到SAW滤波器中以产生 SAW滤波器中的互调扰动。 由于当声表面波的发射功率密度变得太大时产生互调扰乱,所以输入转换器被分割,并且分离的转换器被设置在与声表面波的传播方向垂直的方向上,以降低 传输功率密度。 由于分频转换器串联连接,可以补偿阻抗的减小以及孔径长度的增加。

    • A slide and pin type carburetor using a plate-shaped slide valve in which the lower end surface of a flat plate portion is placed on the same plane as that of a column-shaped portion, the flow rate of air is controlled in the periphery of the column-shaped portion within the region in which the column-shaped portion exists and in front of the flat plate portion within the region in which no column-shaped portion exists, and a cutaway is formed, ranging from the surface located on the upstream side of the lower end of the flat plate portion to the bottom surface of the column-shaped portion, toward the downstream side, in order to make it possible to set properly the level of a negative pressure to be produced without raising abnormally the negative pressure produced in the vicinity of the exit of a main fuel nozzle and to increase the flow velocity of air, without producing any turbulence, in the vicinity of the exit of the main fuel nozzle so that the atomization of the fuel is favorably performed. The cutaway has an inclined surface descending from the upstream side toward the downstream side to shape a part of a conical surface directed to a fuel metering needle mounted on the bottom surface of the column-shaped portion.
