A first adding circuit sums an input image signal of a target pixel and a value that is derived by multiplying respective display errors of three pixels, which are before the target pixel by one line, by weighting factors. A gradation candidate converter converts the gradation of the summed image signal to a plurality of available gradation candidates that are convertible when an error of the immediate left pixel is added. A delaying circuit delays the summed image signal. A second adding circuit sums the delayed image signal and a value that is derived by multiplying the error generated in the immediate left pixel by a weighting factor. A gradation selector selects a gradation closest to the gradation of the image signal to which the error is added from a plurality of gradation candidates, and outputs it as an image signal of the target pixel. A differencing circuit determines a display error of the target pixel.

In a multi-function input/output device, an optical reading unit optically reads an optically readable code from a device control setting medium on which device control setting information, including use authentication information and unit-control-setting information for a document input control setting unit, a document-data-processing control setting unit, and a document-data-output control setting unit, is recorded. The device control setting information including the use authentication information is recognized from the code read by the optical reading unit. A user authentication unit authenticates the user by using a use authentication code of the use authentication information. A setting processing unit sets the unit-control-setting information based on a recognition result of the device control setting information and the use authentication information.

According to one embodiment, a lamp unit comprises a light source lamp, a casing and a dividing member. Configured to hold the light source lamp, the casing comprises a first opening as an inlet port where cooling air is fed from the outside to the light source lamp. The dividing member is provided in the vicinity of the second opening of the casing and is configured to divide the flow of the cooling air into the second opening into at least two paths.

At a terminal where communication can take place via a network, ADF in which property information on data is stored is received, and based upon the communication systems (ordinary/SSL) which were used for receiving this ADF and the communication system which is used for receiving JAR in which the entity of the above mentioned data is stored, whether a communication pattern is allowable determined. JAR is received if the communication pattern is allowable, and JAR is not received if the communication pattern is not allowable for security reasons. In other words, data is obtained only when the communication pattern is allowable.

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.

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.

An IP server sends e-mail to a mobile device MS. This e-mail includes an application specifier that specifies startup of a Java application stored in mobile device MS. On the other hand, the ADF for the Java application stored in mobile device MS includes trusted source data containing a plurality of e-mail addresses that indicate trusted origins. Mobile device MS compares the e-mail transmission origin address with the trusted source data. Mobile device MS, only in the case where the transmission origin address of the received e-mail is included in the trusted source data, starts up a Java application based on an application specifier included in said e-mail.
