摘要:
With a capacitor C inserted in an interstage portion of multiple stages of amplifier circuits, a high pass filter is generated by the capacitor C and an input impedance |Z| of an amplifier circuit in the next stage. Accordingly, frequency components lower than a cutoff frequency fc are cut off, and therefore are not transferred to the subsequent stage. However, radio frequency components higher than or equal to a fundamental wave component determined by an envelope of a radio frequency signal intermittently transmitted can be transferred. Consequently, transfer of DC offset potentials can be cut off, and noise, such as flicker noise, having great power in a DC or near-DC zone can be effectively cut off. Thereby, the S/N ratio, detection sensitivity, and detection accuracy can be improved.

摘要:
A fan motor driving circuit controls an energized state of a fan motor by performing on and off control of a switching circuit connected to a coil of the fan motor of a driving object. A variable reference voltage circuit generates a voltage whose voltage level changes with time by charging or discharging a capacitor at the start of starting up the fan motor. A drive signal combining unit generates drive signals on the basis of the voltage when at least starting up, and performs on and off control of the switching circuit by the drive signals. An initialization circuit initializes the capacitor before starting up with a transition from off to on of a power supply voltage to be supplied to the fan motor driving circuit as a turning point.

Cleaning compositions composed of specific amounts of carbonic acid and/or carbonate, hydrogen peroxide, aluminum fluoride and water are highly effective for cleaning electronic devices of resist, resist residues, titanium dioxide, aluminum oxide and silicon dioxide. The compositions contain no hydroxylamine and are thus free of its hazards.

Soyasapogenol B is biosynthesized via two steps of hydroxylation reaction of its precursor β-amyrin. However, the gene of the hydroxylase concerned in this reaction has not been revealed. Therefore, it was impossible to apply a genetic engineering technique on the hydroxylase. The present inventors reveals that a sequence which corresponds to a soybean-derived cytochrome P-450 gene CYP93E1 encodes an enzyme protein that carries out hydroxylation of the 24-position of an oleanane type triterpene, and also provides a method for applying said gene making use of a genetic engineering technique.

摘要:
A receiver configured to receive a plurality of signals k (k=1, 2, . . . , M) allocated in a first frequency band. The receiver includes a frequency conversion section for reallocating the signals k in a second frequency band for sampling by a single AD converter at a sampling frequency fs such that digital data of the sampled signals k are obtained in a third frequency band extending from zero Hz to a frequency represented by fs/2; and a signal extraction section for extracting a target base band signal k from the digital data obtained by the AD conversion section. The frequency conversion section performs the reallocation in such a manner that at least a frequency represented by Jfs/2 (J is an integer) is located between the frequencies of at least two of the signals k and that the sampled signals do not overlap.
