Abstract: A power supply modulator for an RF power amplifier comprises a combination of a linear amplifier 22 supplying high frequency envelope signals and a switching amplifier 24 supplying low frequency and DC envelope signals. The feedback for the linear amplifier 22 is from the output side of the sense resistor Rsense. The linear amplifier 22 does not need to amplify the LF components of the envelope signal. Efficiency is increased and the output current rating of the linear amplifier can be reduced. The inductor L2 prevents high frequency signals from the amplifier A1 flowing into the switching amplifier 24. The variable resistor R4 sets the average level of the switching amplifier output current.

Abstract: Disclosed is a conductive filler which can be fusion-bonded under lower temperature conditions (with the peak temperature of not less than 181° C.) than the reflow heat treatment conditions for an Sn-37Pb eutectic solder. This conductive filler is applicable to heat-resistant uses similar to those of the Sn-37Pb eutectic solder. The conductive filler is a mixture of first metal particles composed of an alloy having a chemical composition including 25-40% by mass of Ag, 2-8% by mass of Bi, 5-15% by mass of Cu, 2-8% by mass of In and 29-66% by mass of Sn, and second metal particles composed of an alloy having a chemical composition including 5-20% by mass of Ag, 10-20% by mass of Bi, 1-15% by mass of Cu and 50-80% by mass of Sn. In the mixture, 20-10,000 parts by mass of the second metal particles are contained per 100 parts by mass of the first metal particles.

Abstract: The amplitude of the input signal Vin for a class E power amplifier 20 with power supply modulation 18 is adjusted by a predistorter 22 in order to achieve either optimum linearity or power added efficiency. Optimum efficiency is achieved by avoiding underdriving or overdriving of the amplifier 20. Optimum linearity is achieved by adjusting the amplitude of Vin to achieve a linear relation between the output signal magnitude and the supply voltage Vds. The predistorter 22 may alternatively or additionally adjust the phase of Vin to correct the amplifier's phase response. The predistorter 22 may use a lookup table or polynomial equation. An amplitude limiter 16 may be arranged before the predistorter.

Abstract: An azimuth measuring device which can obtain offset information corresponding to one in the case where the direction of the azimuth measuring device is arbitrarily changed, without obtaining erroneous offset information when changing the direction of the azimuth measuring device while retaining its attitude with respect to a specific direction, is provided. A data processing section 19 processes data from a triaxial sensor which detects earth magnetism. In the data processing section 19, triaxial output data at the time when the direction of earth magnetism changes in a three dimensional space are repeatedly obtained not smaller than a predetermined number of times; the coordinates of a point where the variation of distances from a group of triaxial output data is minimum in a three dimensional coordinate which triaxial output data are related to respective axial components is estimated by using a statistical method, and is set as a reference point; offset information is calculated based on the coordinates of the reference point, and it is determined whether the group of triaxial output data is distributed in the vicinity of a specific plane; and when it has been determined that the group of triaxial output data is distributed in the vicinity of the specific plane, the coordinates of a reference point are not estimated, or the coordinates of an estimated reference point is deleted.

Abstract: A non-aqueous secondary battery wherein internal short circuits caused by some kinds of manufacturing processes can be prevented by avoiding the falling of active material particles from end faces of sheet electrodes, and the battery capacity of an electrode plate laminate which can be stored in a battery can of the same size as those of the conventional laminates can be increased without increasing the thickness of the active material layer. In order to realize the features mentioned above, at least one of end face of each of positive electrode active material layers (1b) and negative electrode active material layers (2b) is coated with an aggregation layer of insulating material particles (3F) wherein insulating material particles are bonded with binders. The positive electrode active material layer (1b) is formed in such a size that it may not overhang the negative electrode active material layer (2b) which is paired with the positive electrode active material layer (1b) for a cell layer. A separator is constituted of an aggregation layer of insulating material particles (3B) and is secured to either a positive electrode (1) or a negative electrode (2) or to both of them. The separator is so located that it may cover the entire surface of the positive electrode active material layer (1b) which faces at least the negative electrode (2) and it may not overhang the end faces of the positive and the negative current collector (1a, 2b).
