摘要： PROBLEM TO BE SOLVED: To deliver required information associated with a surrounding environment to a user depending on his/her position and direction.
SOLUTION: A position detection section 21 detects a position of the mobile wireless guide apparatus 20 and a direction detection section 22 detects the direction of the mobile wireless guide apparatus 20. An information selection output section 28 selects and outputs guide object information (e.g. 'an attraction A (B) is held in front (at the back, to the left or to the right') received by an information reception section 24 on the basis of the position and the direction of the guide apparatus 20 and the attribute of the object (e.g. position of the attraction A (B)). For example, the information selection output section 28 selects the information 'the attraction A(B) is held to the left (right)'. Then the mobile wireless guide apparatus 20 can deliver required information depending on the position and direction of a user of the mobile wireless guide apparatus 20.

摘要： PROBLEM TO BE SOLVED: To provide a wireless terminal that can attain downsizing and weight reduction and reduce the SAR(Specific Absorption Rate) which is a power of an electromagnetic wave emitted from a wireless terminal per unit time/unit mass absorbed by a particular part of a human body. SOLUTION: A conductive member 20 is placed around a circumference of an LCD element 12 in a way of surrounding the LCD element 12 and one end of the conductive member 20 is short-circuited to ground. The conductive member 20 distributes SAR peaks to reduce the SAR peaks. Or the conductive member 20 increases the impedance around a feeding point to reduce the SAR. Since the conductive member 20 is placed in a way of surrounding the LCD element 12, no hindrance to the LCD element 12 mounting is caused.

摘要： PROBLEM TO BE SOLVED: To provide a wireless communication device that attains ease of arrangement of a conductive member and reduces a local average SAR(Specific Absorption Rate). SOLUTION: Resonance is caused to the conductive member 20 in the case of communication. Since a lower end 20a of the conductive member 20 is open and an upper end 20b is connected to ground, that is, earthed, the impedance of the lower end 20a is close to ∞(infinitive impedance) and the impedance of the upper end 20b approaches zero. Since the upper end 20b of the conductive member 20 is connected to a part near an antenna feeding section 18, a current supplied form the antenna feeding section 18 flows through the conductive member 20. Then the current supplied from the conductive member 20 less flows to a part around a speaker 12 to reduce radiation of an electromagnetic wave around the speaker 12. Since the conductive member 20 is fitted to a rear side 14b of a shield case 14, the space to locate the conductive member 20 is easily ensured.

At pushing in of a second antenna, a fourth power feeding member 62 is electrically connected to a second power feeding member 59 to electrically connect the antenna 57 and a rod antenna 60 to form a composite antenna. At drawing out the second antenna, a third power feeding member 61 is electrically connected to a first power feeding member 58 to form a composite antenna. A balun 38 prevents leaked current from flowing from the composite antenna.

摘要： PROBLEM TO BE SOLVED: To provide the portable radio equipment where radio wave disturbance due to a head of the user is less to suppress deterioration in speech quality and no hindrance is caused on carrying. SOLUTION: A speaker 23 is projected from a case 22 and the projection is released. Thus, in the case of the portable radio equipment while the speaker 23 is close to an ear of the user when the user makes a speech, a distance between a whip antenna 24 and a head of the user 15 is wider by at least a projected length of the speaker 23. Moreover, when the user releases the projection of the speaker 23 while the user makes no speech, the increase in the entire thickness is avoided.
