摘要： PROBLEM TO BE SOLVED: To make the most of the portable wireless apparatus by making transmission behavior automatically stop to operate as a receive-only terminal within a transmission restricted area of the portable wireless apparatus.
SOLUTION: A position detection section 60 obtains present position information by received GPS signals via an receiving antenna 50 and a position deciding section 73 of a control section 70 decides whether the present position is located within the transmission restricted area by using the present position information. When the present position of own apparatus is located within the transmission restricted area, the control section 70 makes, based on the measurement result of a position, the output of a wireless transmission section 30 stop by a transmission output control section 71, and electric power to the wireless transmission section 30 is shut off by an electric power supply control section 72 so that the wireless transmission section 30 is controlled to be shifted into a non-operation state. Thereby, the wireless transmission section 30 stops operation so that the portable wireless apparatus 1 is converted into the receive-only terminal in which only a wireless receiving section 40 and non-communication functions operate.

摘要： PROBLEM TO BE SOLVED: To provide a portable radio unit that can secure excellent telephone conversation quality in various use states and can be miniaturized in the portable radio unit having a slide structure. SOLUTION: The portable radio unit has a circuit substrate which is provided with an antenna element inside a first casing and has a ground pattern inside a second casing, and a feeding member for feeding power to the antenna element inside the first casing from the circuit substrate. When the first/second casings are slidingly developed, the ground pattern and the antenna element of the circuit substrate are operated as a dipole antenna. When the first/second casings are overlapped, the antenna element is operated as an inverted-L antenna. Consequently, it is possible to achieve a built-in antenna capable of securing high antenna gains in the various use states. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an instrument and system for measuring antenna by which the antenna characteristic of an antenna to be measured can be measured with high accuracy in an actually used state with a simple constitution. SOLUTION: The antenna measuring instrument outputs a first frequency signal from a transmitter 1 and transmits the signal from a first antenna 3. Portable radio equipment 2 receives the first frequency signal through an antenna 4 to be measured, detects the receiving level of the signal by means of a radio section 5, and transmits the information on the receiving level from the antenna 4 after converting the information into a second frequency signal. The instrument receives the second frequency signal through a second antenna 8, and detects the receiving level of the signal by means of a receiver 9. At this time, the portable radio equipment 2 is rotationally driven by means of a turntable 7. A controller 10 obtains the information on the radiation directivity of the antenna 4 by obtaining the information on the receiving level of the first frequency signal at the antenna 4 to be measured from the information on rotational angle of the turntable 7, and the information on the receiving level of the second frequency signal obtained by means of the receiver 9.

摘要： PROBLEM TO BE SOLVED: To provide a selection level-measuring system capable of preventing the mixing of CPU noise in a low-noise amplifier and highly accurate and highly sensitive measurement. SOLUTION: A preamplifier part 1 constituted by embedding a low-noise amplifier 6 in an electromagnetically shielded case is arranged outside a case 4 in which a section level measuring module 2 and a CPU 3 are embedded. By this constitution, it is possible to prevent CPU noise from mixing in the low-noise amplifier 6 and to perform highly accurate and highly sensitive measurement. In addition, by embedding the preamplifier part 1 in the separate case connected to the outside of the case 4, mode conversion between highly sensitive measurement mode and normal level measurement mode becomes easy.
