    摘要: A semiconductor integrated circuit device for communication is provided with a PLL circuit or the like formed therein, the PLL circuit which is capable of realizing the compensation of fluctuation due to temperature change, the inhibition of increase in the chip area and the ensurement of the performance margin, and which controls a VCO having multiple oscillation frequency bands. In the case where automatic calibration is performed by switching a switch to a side of a DC voltage source in the PLL circuit using a VCO having multiple oscillation bands, a tuning voltage (Vtune) of an RFVCO is fixed to a voltage value of a DC voltage source. However, since a temperature characteristic of canceling a VCO oscillation frequency is given to the DC voltage source, it is possible to minimize the influence on the band selection when a calibration table comes to no optimum one.

    摘要: In a communication semiconductor integrated circuit device, an oscillator (VCO 10) of a PLL circuit can operate in a plurality of frequency bands. With a control voltage (Vc) of the oscillator fixed to a predetermined value (VDC), an oscillation frequency of the oscillator is measured for each band to be stored in a storage (18). When the PLL operates, a setting value to specify a band is compared with the measured frequency values stored in the storage. As a result of the comparison, a band to be actually used by the oscillator is determined.

    摘要: The invention relates to a transport cart (10) for loading an aircraft galley, comprising a base element (12) and a plurality of wheels (14) attached to the base element (12). Two frame elements (20, 24) are connected to the base element (12) and disposed at a distance from each other. A first guide device (28, 28′, 28″) is set up for engaging a complementary second guide device formed on a box that is receivable in the aircraft galley to be loaded and for transporting on the transport cart (10). The first guide device (28, 28′, 28″) is further set up for securing the box against displacement on the transport cart (10) in a direction perpendicular to a longitudinal axis (L) of the transport cart (10) when engaged with the complementary second guide device formed on the box. The transport cart (10) finally comprises a locking mechanism (40, 40′) which is set up for securing the box against displacement on the transport cart in a direction parallel to the longitudinal axis (L) of the transport cart (10).
