A mobile communication terminal including a detecting unit configured to detect positional information corresponding to a location of a speaker of the mobile terminal relative to a user’s ear canal, and a controlling unit configured to move the speaker relative to the user’s ear canal based on the positional information detected by the detecting unit. A method of carrying the infant car seat by one carrier. The intermediate cable is connected to the brake cable to set the brakes when the operator cable is wound up by energization of the motor in one direction, with a load sensor turning off the motor when a predetermined tension load is reached. The method also includes determining transition costs based on the co-occurrence values for term pairs, each transition cost indicative of a cost of transitioning from a first term in a first query to a second term in a second query consecutive to the first query. Each first pair, when executed at a replicate database, acts to delete data at a first location identified by each identified insert operation prior to inserting data of the new insert operation at the first location. Thus, the size of the integrated circuit portion can be close to the desired size of the antenna, so that the integrated circuit portion and the antenna are easily connected and the semiconductor device can surely transmit and receive a signal to and from the communication device.
