A portable wireless device realizing high-speed transmission in downlink communication in a used state that a foldable portable wireless device is held in a hand of the user and ensuring a high antenna radiation efficiency. In the portable wireless device, platy conductors (1, 3, 4) are arranged in the longitudinal direction on the back of a display section (35) of an upper case (5). The signal of a transmission circuit (25) is distributed by a power distributor (18). One signal is fed to a platy conductor (1) through a phase shifter (17) and the other is fed to the platy conductor (3) or the platy conductor (4) from a high-frequency switch (19) through a transmission / reception duplexer (20) or a transmission / reception duplexer (21). The high-frequency switch (19) selectively feeds power to either the platy conductor (3) or the platy conductor (4) according to the signal from a gravity sensor (26). The received signal is extracted by the transmission / reception duplexers (20, 21), amplified by a receiving circuit (22) and a receiving circuit (23), and multiplied by a predetermined weight coefficient by a demodulating section (24) and combined.

An improved transmitter apparatus, a receiver apparatus and a base station implemented with the transmitter and receiver apparatuses are described. These apparatuses and the base station serves to establish communication by making use of an orthogonal frequency division demultiplexing demodulation and an inverse spectrum spreading demodulation in combination. The communication coverage thereof can be expaned by making use of an orthogonal frequency division demultiplexing demodulation and an inverse spectrum spreading demodulation in combination.

The main body further comprises: a circular recess containing a central platform; a plurality of first fastening portions spaced along the inner edge of the circular recess; and a channel formed with a positioning block and two symmetrical guide tracks disposed on respective banks thereof. The fixing piece is provided with a rail on each of two sides thereof corresponding to the guide tracks, and with a retaining portion arranged on one side of the fixing piece. The plug contains a circular base corresponding to the circular recess for the plug to rotate in the circular recess of the main body, in which a positioning receptacle at a position corresponding to the positioning cylinder is centrally formed in the circular base; a plurality of second fastening portions is arranged surrounding the circumferential edge of the circular base corresponding to the first fastening portions for buckling the plug with the main body; and a gap is defined in the circumference of the circular base of the plug and correspondent to the retaining portion of the fixing piece such that the plug can be fixed in the circular recess.

A fault diagnosis method of diagnosing a fault related to a PV PCS 150, configured to perform an interconnected operation in which a PV 100 is interconnected to a grid 10: supplies power from independent operation output of the PV PCS 150 to a storage PCS 250 by an independent operation that does not interconnect the PV 100 to the grid 10 after the grid interconnection apparatus stops the interconnected operation by detecting abnormality; measures an output power state of the PV 100 and / or the PV PCS 150 when power is supplied to the storage PCS 250; and determines that the fault occurs and performs an error process for notification to a user when the measured output power state does not satisfy a predetermined condition.

Parameters are set in accordance with a running condition of a vehicle and an environmental condition based on a wiper operation signal of the vehicle. The parameters are used to calculate a stable vehicle interior surface temperature Tna of a window glass. The stable vehicle interior surface temperature Tna and a vehicle interior surface temperature Tn1 calculated at previous sampling are used to calculate a vehicle interior surface temperature Tn in a transient state considering response delay time τ of temperature change. A control temperature, at which no dew is formed on the window glass, is determined in accordance with the obtained vehicle interior surface temperature Tn to perform air conditioning control.
