Abstract: PROBLEM TO BE SOLVED: To provide an ac power amplifier that attains high efficiency over a wide range of input amplitude in an LINC system amplifier. SOLUTION: The ac power amplifier includes a branching filter circuit 90 that divides an input signal input from an input terminal 1 into two constant amplitude ac signals and changes them so that a phase difference of the ac signals may correspond to the amplitude of the input signal, and two saturation amplifiers 10 and 20 with FETs 12 and 22 that operate in the saturated regions, which amplify the two constant amplitude ac signals respectively. The amplified signals amplified by the respective saturation amplifiers are synthesized at a synthesis point, and they are output from an output terminal 2. The drains of the FETs 12 and 22 and the synthesis point 39 are connected by means of transmission lines 32 and 33 that gives a delay equivalent to about one-fourth wavelength to the basic wave of the ac signal to be amplified, and a capacitor 34 that reflects harmonic waves and causes a reflection phase of harmonic wave seen at the load side from the synthesis point 39 to be an opposite phase is provided at the synthesis point 39.

Abstract: PROBLEM TO BE SOLVED: To calibrate a scale factor of a vibration velocity sensor by generating vibration motion having large amplitude and using the vibration motion.
SOLUTION: The vibration velocity sensor S to be calibrated is placed on a rotary table 14 coupled to a rotary drive source built in a rotary unit 12 so that an input shaft of the vibration velocity sensor S matches with the rotation direction of the rotary table 14. The rotary table 14 is rotated and vibrated at a certain rotation frequency so that the vibrating vibration velocity is input to the vibration velocity sensor S. The output signal from the vibration velocity sensor S is obtained, and the scale factor of the vibration velocity sensor S is calculated from the obtained output signal.

Abstract: PROBLEM TO BE SOLVED: To provide an electric wave range finder for temperature compensation with a simple configuration. SOLUTION: A transmission leakage signal which leaks into a reception circuit 3 instead of advancing from a transmission circuit 1 to an antenna 4 while the transmission circuit 1 is connected to the reception circuit 3 is affected by temperature change, resulting in change of position and intensity of the transmission leakage signal. A reception signal is affected by temperature change. A reference value for position or intensity of the transmission leakage signal is stored in a memory 9 in advance, which is compared with the position or intensity of actually measured transmission leakage signal. Compensation is performed based on the comparing result.

Abstract: PROBLEM TO BE SOLVED: To perform photographing without being affected by external light from a second observation area, using an imaging apparatus which includes an observed area to dispose an object to be observed therein and a first observation area to dispose therein a camera for imaging the object to be observed, the object being visible from the second observation area that is an area separated from the first and second observation areas. SOLUTION: Between the observed area 12 and the first observation area 14, a first polarizer 30 is disposed for transmitting only a first linearly polarized component polarized in a predetermined first direction and between a second observation area 16 and the observed area 12, a second polarizer 32 is disposed for transmitting only a second linearly polarized component in a direction approximately orthogonal to the first direction. When light from a second light source 28 passes through the second polarizer 32, only the second linearly polarized component is passed and reflected on an object 20 to be observed. Thereafter, the second linearly polarized component can not be passed through the first polarizer 30, so that the light from the second light source 28 reaches a camera 22 while being attenuated. Thus, on a screen imaged by the camera 22, the influence of light from the second light source 28 is reduced. COPYRIGHT: (C)2010,JPO&INPIT
