    摘要： An MR/FIR light detector is disclosed herein that has extraordinarily high degree of sensitivity and a high speed of response. The detector includes an MR/FIR light introducing section (1) for guiding an incident MR/FIR light (2), a semiconductor substrate (14) formed with a single-electron transistor (14) for controlling electric current passing through a semiconductor quantum dot (12) formed therein, and a BOTAI antenna (6, 6a, 6b, 6c) for concentrating the MW/FIR light (2) into a small special zone of sub-micron size occupied by the semiconductor quantum dot (12) in the single-electron transistor (14). The quantum dot (12) forming a two-dimensional electron system absorbs the electromagnetic wave concentrated efficiently, and retains an excitation state created therein for 10 nanoseconds or more, thus permitting electrons of as many as one millions in number or more to be transferred with respect to a single photon absorbed.

    摘要： A power accumulating unit of a power supply system includes a first switch section configured to achieve a first voltage output state in which an output voltage is substantially equal to a first motor driving voltage and a second switch section configured to achieve a second voltage output state in which the output voltage is substantially equal to a second motor driving voltage that is higher than the first motor driving voltage. A voltage switching control part is configured to perform a voltage switching control to switch between the first motor driving voltage and the second motor driving voltage by alternately operating the first and second switch sections to repeatedly switch between the first voltage output state and the second voltage output state.

    摘要： An infrared light condensing apparatus that focuses an infrared light of several tens microns in wavelength at a microfine area of submicron or less and also a near-field from a microfine area of submicron or less, and permits a scanning image to be obtained. It includes a solid immersion lens including a medium of high index of refraction for coupling an incident light or an outgoing light to an antenna, a measured specimen disposed on a base plane of the solid immersion lens, an antenna disposed away from the base plane at a distance ¼ of an effective wavelength of the light for causing the light to geometrically resonate therewith, a rod-like conductive probe having a sharply point end projecting from the antenna, and a position control means such as a triaxial XYZ mechanical stage for controlling the position of the probe with the intermediary of a cantilever.

    摘要： An infrared light detector with an infrared light sensitivity thereof further improved. According to the infrared light detector, an isolated region of a first electronic layer is switched between a “disconnected status” and a “connected status”. Under the connected status, saturation of an electrostatic charge quantity of the isolated region in the disconnected status is eliminated, and consequently, saturation of a variation amount of an electrical conductivity of a second electronic layer is eliminated. Therefore, the infrared light sensitivity is further improved by time integration of the variation amount of the electrical conductivity of the second electronic layer.

    摘要： In a micro-bridge structure in which a temperature detecting portion 14 (diaphragm) including a bolometer thin film 7 is supported by a supporting portion 13 in a state floated from a circuit substrate 2, a reflective film 3 reflecting a THz wave is formed on the circuit substrate 2, an absorbing film 11 absorbing the THz wave is formed on the temperature detecting portion 14, and an optical resonance structure is formed by the reflective film 3 and the temperature detecting portion 14. And a gap between the reflective film 3 and the temperature detecting portion 14 is set approximately ¼ of a wavelength of an infrared ray on the basis of the wavelength of the infrared ray (in a range of approximately 1.5 to 2.5 μm, for example), and a sheet resistance of the temperature detecting portion 14 is set in a range in which an absorptance of the THz wave becomes a predetermined value or above on the basis of the THz wave (in a range of approximately 10 to 100 Ω/sq.). By this arrangement, the absorptance of the THz wave is drastically improved while using the structure and manufacturing technique of a bolometer-type infrared detector.
