摘要： PROBLEM TO BE SOLVED: To provide a system/a method which enable a certificate to be issued online with the help of a printer, provided that it meets a specified function, without the use of a specific sheet or a specific printing device and also the validity of a certificate to be simply verified by a verifier. SOLUTION: In this method for issuing a certificate, a pasteboard issuance/manager system comprises a means to manage the identification number of a pasteboard and a means to write the coded identification number to pasteboard data. In addition, a certificate issuer system comprises a means to add an electronic signature of a certificate issuer to individual piece of data to be overwritten to the pasteboard data; a means to replace the coded individual pieces of data with coded information which can be read by an information processing device; a means to insert the identification number of the pasteboard in the form of an electronic watermark, in case image data are added to the individual pieces of data; and a means to arrange the above processed coded information, image data and individual pieces of data on the pasteboard data in such a way that these data and information are not superposed over each other. Also, the method for verifying a certificate is provided. COPYRIGHT: (C)2005,JPO&NCIPI

摘要：エネルギー回復インダクタ（Ｌ１）を有するマトリクスディスプレイ駆動回路において、スイッチ回路（Ｓ３、Ｄ３、Ｓ６、Ｄ９）をこのインダクタ（Ｌ１）に並列接続して、ループ内のインダクタ電流（ＩＬ１）を最小限に保って、インダクタ（Ｌ１）の両端の電圧（ＶＬ１）を最低限に保つ。結果的に、インダクタに蓄積されるエネルギーをより少なくして、インダクタ（Ｌ１）と寄生容量Ｃｊとの寄生共振によって生じるＥＭＩを大幅に低減することができる。

摘要： PURPOSE:To eliminate the increase in processing time as a system by an increase in the contents of the processing items of a CPU by simultaneously executing the reading out control from an encipherment processing circuit and the writing control to an external circuit. CONSTITUTION:The latch output data 110 of an output data selection circuit 15 and an output data latching circuit 14 are automatically outputted successively from the higher order when the prescribed count-up is executed by a clock 105 to output an output data selection circuit control signal 112 after an output data selection control counter 16 is enabled. A writing signal control circuit 17 outputs an external circuit writing signal 115 for writing the output data into an external circuit in accordance with the clock 105 when the output data selection control counter circuit 16 outputs a writing signal control circuit enable signal 114 to enable the circuit 17. The need for the CPU is eliminated for the output control of the data and the writing control to the external circuit in this way and, therefore, the excess of the processing time arising when the CPU executes the control is eliminated in this way.
