摘要： A photopolymerization initiator comprising an iodonium salt compound; and a photocurable composition containing the compound. The composition is a photocurable cationic composition which cures in a short time upon irradiation with actinic energy rays. They are based on the following findings: (1) a colorless lowly toxic iodonium salt compound can be easily synthesized in high yield when a specific substrate is used as a starting material; (2) a photocurable composition curing in a short time to give a cured article having excellent material properties is obtained by using the iodonium salt compound in combination with a sensitizer; and (3) a highly sensitive photocurable composition which upon irradiation with actinic energy rays cures in a short time to give a cured article having excellent material properties is obtained by using a compound having a group functioning as a cationic photopolymerization initiator, a sensitizing group accelerating the phtoinitiated cationic reaction, and a cationically polymerizable group in the same molecule.

摘要： An improved DRAM includes an internal circuit to be initialized upon start of supply of a supply voltage. The DRAM includes a dummy clock signal generator, and applies a dummy clock signal to a clock signal generator through a switching circuit until a predetermined time period elapses after the start of supply of the supply voltage by a timer circuit. A signal /RAS is controlled in a special manner, is not required for initializing an internal circuit such as a refresh counter. Therefore, a load required in the external circuit for initialing the DRAM is reduced.

摘要翻译： 改进的DRAM包括在开始供应电源电压时被初始化的内部电路。 DRAM包括虚拟时钟信号发生器，并且通过开关电路将虚拟时钟信号施加到时钟信号发生器，直到定时器电路在电源电压供应开始之后经过预定时间段。 以特殊方式控制信号/ RAS，不需要初始化诸如刷新计数器的内部电路。 因此，用于初始化DRAM的外部电路所需的负载减小。
