摘要： Provided is an impedance matching device for matching an impedance between a high-frequency power source and a load. The impedance matching device pertaining to the present invention is provided with: a matching circuit having variable capacitors, a capacitance of which is adjusted by an ON/OFF operation of a plurality of switches; a switch control unit for performing control for causing states of the switches of the variable capacitors to coincide with a target state in order to adjust the capacitance of the variable capacitors; and a switch state evaluation unit for evaluating whether a switch is in a state requiring suppression of a temperature increase. The switch control unit is configured so that when the switch state evaluation unit evaluates that a switch of the variable capacitors is in a state requiring suppression of a temperature increase, control is performed for suspending changing of a switch state of the switch for a set period and suppressing a temperature increase in the switch.

摘要： An electrical circuit comprising at least two negative capacitance insulators connected in series, one of the two negative capacitance insulators is biased to generate a negative capacitance. One of the negative capacitance insulators may include an air-gap which is part of a nanoelectromechnical system (NEMS) device and the second negative capacitance insulator includes a ferroelectric material. Both of the negative capacitance insulators may be located between the channel and gate of a field effect transistor. The NEMS device may include a movable electrode, a dielectric and a fixed electrode and arranged so that the movable electrode is attached to at least two points and spaced apart from the dielectric and fixed electrode, and the ferroelectric capacitor is electrically connected to either of the electrodes.

摘要： Energy storage devices are disclosed that store both electrical and mechanical energies, making the total energy stored larger than either an electrical or mechanical means alone. The energy storage device is charged by the application of a voltage, which charges a capacitor to store electrical energy while simultaneously exerting a force on the mechanical system that deforms the mechanical system, resulting in mechanical energy storage. When the charged device is discharged, both the electrical and mechanical energy are extracted in electrical form. Its unique features include, but are not limited to, the potential for long lifetime, improved safety, better portability, a wide operating temperature range, and environment friendliness. Arrays of energy storage devices can be assembled in various configurations to build high capacity energy storage units.

摘要： A variable capacitor, including: two movable plates, two poles, and one rotary shaft. The two movable plates are conductor belts, and the conductor belts are sheathed in insulators. The two poles are conductors, and each is capable of rotating around an axis thereof. First ends of the two movable plates are connected via the insulators and fixed on the rotary shaft, and second ends of the two movable plates are connected to the two poles, respectively. A conductor member of the two movable plates directly contacts the two poles. The lengths of the two movable plates are identical, and are greater than the distance from one pole to the rotary shaft.
