A portable wireless communication apparatus is provided with antenna elements; a mobile phone signal processing circuit; a DTV tuner for receiving DTV low-band frequency signals and DTV high-band frequency signals; impedance matching circuits for the mobile phone signal processing circuit; and impedance matching circuits for the DTV tuner for receiving the DTV low-band frequency signals and DTV high-band frequency signals. A switch is changed to select either the DTV low-band frequency signals or the DTV high-band frequency signals, and output the selected signals to the DTV tuner. A tuner controller controls the switch to select the DTV high-band frequency signals by using the antenna element for transmission from the mobile phone signal processing circuit.

According to the present invention, even though the paint is filled or discharged repetitively to or from the paint bag (5), so that bursting of a coating bag (5) or lack of coating material during coating are not caused by accumulation of error between the filling amount and the using amount.That is, before a predetermined amount of the coating material is supplied to the coating material bag (5), the remaining coating material in the coating material bag (5) is extruded to empty it, since the coating material bag (5) is squashed by the pressure of fluid which was supplied to the hydraulic fluid chamber (6) outside of the bag.

A data processing device which selects either emission of electrons from a nonvolatile memory cell or injection of electrons into it for each bit. A memory array includes a plurality of nonvolatile memory cells each having a pair of a first MOS transistor and a second MOS transistor where the first transistor has a charge retention layer and a memory gate and is used for data storage and the second transistor has a control gate and selectively connects the first transistor to a bit line. When negative voltage is applied to a memory gate, electrons held by a charge retention layer are emitted through hot carriers generated in a nonvolatile memory cell channel region for erasing; and when positive voltage is applied to the memory gate, electrons are injected into the charge retention layer through hot carriers generated in the nonvolatile memory cell channel region for writing and controls the generation and suppression of hot carriers by means of bit line voltage on each bit line.

摘要:
Two LED arrays are connected in parallel, and the both ends of the parallel connection are connected to an alternating-current power supply AC. In each of the LED arrays, a capacitor and three LED blocks (the total of four components) are connected in series. In each of the LED blocks, two LEDs are connected in opposite directions. Connection points between components included in one of the two LED arrays are individually connected to connection points between components included in the other one of the two LED arrays via varistors. Even in the event that a disconnection failure occurs at any one of the LEDs, a path of a current via one of the varistors is formed for another one of the LEDs which is connected in series to the LED at which the disconnection failure has occurred. This can prevent the other LEDs from being turned off. Even in the event that a short-circuit failure occurs at any one of the varistors, the normal lighting operations of the LEDs can be maintained unless the LEDs have defects.

The read speed of an on-chip nonvolatile memory enabling electric rewrite is increased. The nonvolatile memory has a hierarchal bit line structure having first bit lines specific to each of a plurality of memory arrays, a second bit line shared between the plurality of memory arrays, a first selector circuit selecting the first bit line for each of the memory arrays to connect the selected first bit line to the second bit line, and a sense amp arranged between the output of the first selector circuit and the second bit line. The hierarchal bit line structure having the divided memory arrays can reduce the input load capacity of the sense amp.
