    • The invention provides a process for producing a chroman compound represented by formula (1), characterized in that the process includes allowing a phenol, an unsaturated compound, and a formaldehyde to react in the absence of catalyst and in the presence of water in an amount by mole 1 to 10 times that of the phenol.According to the present invention, a high-purity chroman compound can be produced in the absence of catalyst and under mild conditions. In addition, the invention provides an industrial means for producing the compound, without using a large amount of an acid or a base serving as a reaction promoter or a catalyst, which would otherwise cause side reactions, apparatus corrosion, etc.

    • A protection circuit with suppressed erroneous operation due to power source fluctuation has a first resistor and a capacitor connected in series between a power source line and a ground line, an inverter with an input connected between the first resistor and the capacitor, and a MOS transistor with a gate electrode that receives an output of the inverter and with a drain electrode and source electrode connected to the power source line and the ground line. When a high voltage fluctuation occurs in the power source line, a level change at a connection point between the first resistor and the capacitor is delayed according to a time constant. By the delay, the MOS transistor that receives an output of the inverter is temporarily turned on and discharges a high voltage to the ground line.
    • 由于电源波动导致的具有抑制的错误操作的保护电路具有串联连接在电源线和地线之间的第一电阻器和电容器,连接在第一电阻器和电容器之间的输入的反相器和MOS晶体管 其中栅电极接收反相器的输出,并且漏电极和源电极连接到电源线和接地线。 当电源线发生高电压波动时,第一电阻和电容器之间的连接点处的电平变化根据时间常数被延迟。 通过延迟,接收逆变器的输出的MOS晶体管暂时导通,并将高电压放电到地线。

    • Techniques suitable for recovering energy from a high-temperature gas of an ordinary pressure are provided. A turbomachine has a turbine 16 and compressors 20 and 24. A combustor 12 is disposed at a stage above the turbine 16. A power generating system generates power by passing a working fluid for the turbomachine through the combustor 12, the turbine 16 and the compressors 20 and 24 in that order. An atmospheric pressure combustion turbine system includes: a regenerative heat exchanger 14 capable of cooling a high-temperature working gas discharged from the turbine 16 by making the high-temperature working gas exchange heat with a mixed gas produced by mixing an exhaust gas and air and moistened with hot water; coolers 22 and 26 connected to the entrance of the compressors 20 and 24, respectively, to cool the working gas by making the working gas exchange heat with water; and a humidifier 30 for producing a mixed gas by heating air by mixing part of the exhaust gas discharged from the compressor in the air and humidifying the heated air with the hot water produced by heating water by the heat of the working gas through heat exchange. The mixed gas produced by the humidifier is supplied to the regenerative heat exchanger 14, the regenerative heat exchanger 14 produces a high-temperature, humid, mixed gas by making the mixed gas exchange heat with the high-temperature working gas discharged through the exit of the turbine 16 to heat the mixed gas, and the heated, high-temperature, humid, mixed gas is supplied to the combustor 12.
