    • Technology that enables writing in a PDP to be conducted effectively, even when a time period of the writing is shortened. In a PDP driven by a method in which a write discharge is selectively generated in a plurality of cells by applying a scan pulse sequentially to a plurality of first electrodes and a data pulse selectively to a plurality of third electrodes in a write period, the technology provides for a write auxiliary discharge to be generated at least in a cell selected for writing or in a vicinity of the selected cell when the scan pulse is applied in the write period, the write auxiliary discharge being smaller in magnitude than the write discharge. The write auxiliary discharge results in the generation of priming particles in or in a vicinity of the selected cell, and these priming particles facilitate the generation of a write discharge in the selected cell. Consequently, the occurrence of defective writing is reduced and effective writing can be conducted, even when a width of the scan pulse is shortened.
    • 即使缩短写入时间,也能够有效地进行PDP的写入的技术。 在通过在写入周期中通过向多个第一电极依次施加扫描脉冲和选择性地向多个第三电极进行数据脉冲而在多个单元中选择性地生成写入放电的PDP驱动的PDP中, 当在写入周期中施加扫描脉冲时,至少在选择用于写入的单元格中或在所选单元附近产生写入辅助放电,写入辅助放电的幅度比写入放电小。 写入辅助放电导致在所选择的单元中或附近产生引发颗粒,并且这些引发颗粒有助于在所选择的单元中产生写入放电。 因此,即使缩短扫描脉冲的宽度,也可以减少写入不良的发生,并且可以进行有效的写入。

    • The present invention provides a process for producing 5-iodo-2-methylbenzoic acid through iodination of 2-methylbenzoic acid, the process including, as essential steps, a reaction step of iodinating 2-methylbenzoic acid in the presence of a microporous compound, iodine, an oxidizing agent, and acetic anhydride, and a purification step including sublimation, distillation, crystallization, or a combination of two or more of these. According to the present invention, 5-iodo-2-methylbenzoic acid, which is useful for producing functional chemicals such as drugs, can be produced at high purity and high yield in a simple manner. Since the production process includes a simple reaction step and a simple separation/purification step, the load of purification is mitigated. In addition, the microporous compound such as a zeolite catalyst which has been separated and recovered from the reaction mixture can be repeatedly employed after performing of a simple treatment. Thus, the production process ensures a long service life of catalysts and high efficiency.

    • A wavelength conversion apparatus includes: multiplexer that multiplexes pumped light and signal light; wavelength conversion element that wavelength-converts linearly polarized light components in x direction with respect to the pumped light and the signal light, and generates output light polarized in x direction; and light circulator that allows the light of the multiplexer to be output to the wavelength conversion element and allow the light from the wavelength conversion element to be output to the port; reflecting mirror; and Faraday rotator that makes a polarization direction difference of 90 degrees between light traveling from the wavelength conversion element to the reflecting mirror and light reflected at the reflecting mirror so as to return to the wavelength conversion element. Intensity IL of the output light does not depend on the incident polarization angle &phgr; of the signal light &lgr;s and is constant.
