An internal operation of RF IC is adjusted so that the level of an RF transmitter signal is substantially stopped from rising, or made to descend in course of ramp-up of the RF transmitter signal. This adjustment is enabled by ramp-up adjustment data Last 4 symbols contained in preamble data precedent to real transmission data transmitted after completion of ramp-up. The ramp-up adjustment data and real transmission data are supplied from a baseband LSI. The RF transmitter signal contains phase and amplitude modulation components according to the EDGE system. RF IC includes phase and amplitude modulation control loops PM LP and AM LP. Ramp-up of RF power amplifiers PA1 and PA2 is performed by controlling the gain of the first variable amplifier MVGA included in the AM LP according to ramp information. Thus, unwanted radiation's level is reduced during ramp-up of the RF transmitter signal of the RF power amplifiers.

A market-demand-forecasting-value calculation section acquires order entry actual achievement data from an order-entry-actual-achievement-data storing unit of an order receiving system, and calculates a market demand forecasting value using the order entry actual achievement data. A correction safety inventory quantity calculation section calculates an error rate, which becomes negative when an ordering required-quantity becomes large, based on a number of ordered parts and a past ordering required-quantity. Subsequently, the correction safety inventory quantity calculation section calculates a correction safety inventory quantity using the error rate and the market demand forecasting value and a money-amount-zone index value. Further, the correction safety inventory quantity calculation section calculates a determined safety inventory quantity which is a value obtained by adding the correction safety inventory quantity and a reference safety inventory quantity calculated based on the market demand forecasting value.
摘要:
A semiconductor integrated circuit having a built-in PLL circuit which has two charge pump circuits for charging and discharging capacitive elements of a loop filter in response to signals generated by a phase comparator circuit. One of the two charge pump circuits has current sources which generate current values smaller than those generated by current sources of the other charge pump circuit. The loop filter has a first capacitive element connected to a charge/discharge node, and a second capacitive element connected to the charge/discharge node through a resistive element. The first capacitive element is charged and discharged by the one charge pump circuit, while the second capacitive element is charged and discharged by the other charge pump circuit. A charging current source of the one charge pump circuit operates simultaneously with a discharging current source of the other charge pump circuit, i.e., the charge pump circuits operate in opposite phase.

A sheet identifying device and method for identifying the kind of sheet or checking whether a sheet is a genuine or counterfeit one correctly without influence of the state of the sheet. Data on the image of a sheet is acquired, and the image data is binarized according to a watermark region extraction threshold. Image data on the watermark region is extracted according to the sheet image data. The watermark region image data is binarized according to a watermark pattern extraction threshold. The center of gravity of the watermark region is calculated on the basis of the watermark region image data. The watermark region image data is divided into divisions using the center of gravity of the watermark region as the origin. From the watermark region image data, image data on a predetermined specific region is extracted. Values of distinctive features such as the center of gravity and area of the watermark pattern included in the specific region image data are extracted. According to the value of distinctive feature, the kind of the sheet is identified and the sheet is authenticated.
