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.

An event obtaining unit 121 obtains an event generated in an event generation unit 110 and outputs the event to the event providing unit 122. When an operation mode is mode A, the event providing unit 122 refers to an event table T1 and provides the event to an application corresponding to the event. If the event is provided to a communication AP 131, the communication AP 131 is launched prior to providing the event. On the other hand, when the operation mode is mode B, the event providing unit 122 provides the event to a Java runtime environment 140. In addition, the event providing unit 122 changes the operation mode when a switching button CB is pressed.

If an e-mail is sent to a user of a communication terminal while the communication terminal is being used for voice communication, informing the user that the e-mail has been sent is controlled. Mobile phone 500 stores an importance level in association with a telephone number and e-mail address. If a mail alert is received while mobile phone 500 is used for voice communication, an importance level of the voice communication partner and an importance level of the sender of the e-mail are read from a nonvolatile memory. The read importance levels are compared by mobile phone 500, and if the importance level of the sender of the e-mail is higher, mobile phone 500 informs the user thereof that it has received the mail alert.

In a terminal device equipped with a function of running an application program, operation of an application program is suspended when an event is detected, the type of the event is predetermined, and event data representing the detected event is stored. Then, the terminal device delivers stored event data to the application program, after the suspended application is resumed.

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.

An infinite Speed ratio continuously variable transmission comprises a power recirculation mode clutch (9) and direct mode clutch (10). At least one of the power recirculation mode clutch (9) and direct mode clutch (10) comprises an electromagnetic two-way clutch. The electromagnetic two-way clutch maintains the engaged state during excitation and can transmit drive force from both the drive side and non-drive side. On the other hand, when there is a change-over from the energized state to the non-energized state, a one-way clutch state is obtained wherein drive force is permitted only in the transmission direction of drive force in the instant of the change-over to non-excitation. When a drive force is input in the reverse direction to the drive force transmitted in the one-way clutch state, the one-way clutch state is disengaged, and the disengaged state of the clutch is maintained until subsequent re-excitation. Therefore, change-over of the clutch at the rotation synchronous point RSP where the power recirculation mode and direct mode are changed over, can be performed rapidly.
