Title: Antenna apparatus for azimuth measuring apparatus
Inventor: YASUDA TAKESHI
IPC: G01S3/04
Filed: 1980-10-20
Abstract: PURPOSE: To obtain a phase modulated wave corresponding to the coming direction of a radio wave by synthetizing the output of several antennas arranged on one circumference through amplitude modulation with a low frequency signal at a phase angle corresponding to the position of the antennas.  
     CONSTITUTION: Four vertical dipole antennas AnWAe are arranged at an equispace on one circumference. The outputs of these antennas are applied to modulators MnWMe to effect a amplitude modulation with low frequency signals of TnWTe. The signals of TnWTe shall be deviated by 90° corresponding to the direction of the antennas. When the value of 2l is smaller enough than the wavelength λ, a carrier component T o  obtained from the synthetizing of the output of modulators MnWMe is the result of a phase modulation by a low frequency signal with a phase deviation of a certain value. So, the output is demodulated to determine a difference in the phase between the reference low frequency and the demodulation signal. This indicates the coming direction of the radio wave. In this method, any frequency received can be measured simply even when it varies in a wide range.

Title: Light receiving device and image pick-up apparatus
Inventor: AKAGAWA KEIICHI
IPC: H01L31/10
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To enable keeping an SN ratio and a dynamic range at high levels by controlling a power supply with a drive control means and automatically controlling a drive power of cooling means with an automatic control means. SOLUTION: Since the drive control means 14 intermittently supplies a power having so small a value that a deviation of temperature characteristics of a temperature sensor 13 may be allowed, a power is smaller and thereby a noise level is also reduced, compared with the case where a power at the extent is constantly supplied. The automatic control means 5 has an operating temperature as a control quantity, wherein the operational temperature is given by temperature characteristics for an electric resistance of the temperature sensor 13 during a period when a power is supplied, and automatically controls a drive power of the cooling means 12 using the operational temperature at which a photoelectric conversion means 11 conducts photoelectric conversion as a target. The cooling means 12 cools the photoelectric conversion means 11 according to the drive power therefor.  Therefore, the operational temperature of the photoelectric conversion means 11 is kept at a value at which photoelectric conversion can be performed and reduction in S/N ratio caused by a noise is suppressed.

Filed: 1981-09-16
Abstract: PURPOSE:To prevent frequency characteristics from being deteriorated even during dubbing by regarding the frequency multiplex signal, consisting of a  luminance signal and a signal to be frequency-modulated by a color channel signal, as a recording signal in the signal form of the signal to be modulated. CONSTITUTION:A luminance signal Y outputted from a generator 1 for a color TV video signal is supplied to an adder 28. A color difference signal generated by the generator, i.e. a signal (R-Y) is supplied to an adder 13 as one input, and a signal (B-Y) is applied to the adder 13 as the other input through a polarity inverter 12. The output signal of the adder 13 consists of deformed signals of the signals (R-Y) and (B-Y) multiplexed while a band is shared and is regarded as one color channel signal to be supplied as a signal wave to a frequency modulator 14. The modulator 14 outputs a frequency-modulated signal as the other input to the adder 28. Therefore, the adder 28 outputs a recording signal generated by multiplexing the luminance signal Y and the signal frequency-modulated by the color channel signal.

Filed: 1993-06-17
Abstract: PURPOSE:To improve measuring certainty keeping ambient environmental conditions constant even in the measurement of a plurality of subjects by providing a movable carrier plate of the subjects to convey the subjects sequentially to a measuring position. CONSTITUTION:A movable carrier plate 8 for subjects keeps a plurality of subjects 13 and 14 to convey the subject 13 (or 14) sequentially to a measuring position at an opening of a cavity resonator 4.

Thereafter, while environmental conditions in the measuring chamber are kept, the subject 13 (or 14) is moved to be removed from the measuring position while the subsequent subject 14 (or 13) is moved to the measuring position to measure. This enables measuring of high frequency characteristics of the plurality of subjects 13 and 14 continuously while the ambient environmental conditions are kept constant.

Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To make it possible for an observer to surely observe a whole display area of a reflection type liquid crystal display device by arranging a light source at a position where an angle formed between a specularly reflected direction of a beam of light made incident on a reflection type liquid crystal display from a light source of an illuminator and a viewing direction of the observer to a display screen becomes a specific value or smaller. SOLUTION: An emission spectrum of a light source 4 is designed so as to agree with a wavelength area of light required for a display on a display screen 5. Therefore, if the light source 4 is arranged at such a height as a direction in which a beam of light made incident on a reflection type liquid crystal display device 2 from a light source is specularly reflected forms an angle of 50 deg. or smaller with a direction of an observer's visual angle, the light scattered by the reflection electrode reaches the observer, and he can observe the display screen 5. Thus, if a piece of light source 4 is arranged above the center of the long side of the display screen 5, it is unnecessary to arrange the light source 4 at a high position, therefore, this arrangement makes it possible to design an illuminator 1 compactly.

Title: Instantaneous reactive and effective power compensating device
Inventor: NANBAE AKIRA
IPC: H02J3/01
Filed: 1985-07-05
Abstract: PURPOSE:To suppress the voltage fluctuation of a DC capacitor owing to a sudden change of load and to avoid application of overvoltage to a switching element, by providing a means to make the DC capacitor voltage follow the fixed target value. CONSTITUTION:A voltage controller 8 compares the voltage command value with the detected value Vcd of voltage of the DC capacitor and produces a correction signal PAV. An overvoltage detecting circuit 6 produces an output signal ST when the value Vcd exceeds a prescribed level. An analog switch 5 controlled by the signal ST turns on and off the real power compensating signal sent from an HPF 2. Thus it is possible to make the DC capacitor voltage follow the fixed voltage command value. Furthermore a switch 2 cuts the real power compensating signal even thought the load has a sudden change. As a result, the fluctuation of the DC capacitor voltage is suppressed. This prevents such a case where the overvoltage is impressed to the switching element forming a 3-phase PWM converter.
