摘要:
There is provided a secondary battery tester for testing a state of a secondary battery based on an impedance characteristic of the secondary battery. The tester includes: an impedance acquiring section configured to acquire an impedance value of the secondary battery; and a determining section configured to determine a state of a solid electrolyte interface (SEI) layer of the secondary battery based on the impedance value acquired by the impedance acquiring section.

A semiconductor storage device includes a plurality of integrated memory cells. Each cell includes a first inverter having a first driver transistor and a first load transistor which are formed on a semiconductor substrate in order to form a first storage node, a second inverter having a second driver transistor and a second load transistor which are formed on the semiconductor substrate in order to form a second storage node, a first transfer transistor connected between the first storage node and a bit line to serve as a transistor connecting the memory cell to the bit line, and a second transfer transistor connected between the second storage node and a complementary-bit line to serve as a transistor connecting the memory cell to the complementary-bit line.
摘要:
A modulation ratio enhancement circuit increases the modulation ratio of a current signal which is ASK-modulated with signal data. A branch unit, an average value detection unit, a comparator and a buffer constitute a demodulation unit so that the signal data is demodulated from a current signal of which the modulation ratio is increased by the modulation ratio enhancement circuit.
摘要:
A shunt regulator performs a control so as to stabilize a voltage obtained by rectifying the radio frequency signal output from an antenna unit at a prescribed voltage value. A signal extraction unit extracts the information signal from a bypass current sent by the shunt regulator for the control when the voltage fluctuates.
