Title: Light beam modulating device
Inventor: KURANISHI HIDEAKI
IPC: H04N1/04
Filed: 1992-10-12
Abstract: PURPOSE:To provide the light beam modulating device which reduces leakage of a light beam from an optical modulator. CONSTITUTION:In an AOM driver 20 which outputs a high frequency signal to drive an AOM 18, mixers 71AB to 71GH are used instead of a switch circuit which is turned on/off in accordance with the picture recordable range. The on/off control circuit which supplies a control signal to mixers 71AB to 71GB controls mixers 71AB to 71GH so that they allow the inputted signal to pass through (turning-on state) or cut off the inputted signal (turning-off state). Thus, the noise outputted at the time of turning-on/off is reduced to about 1/5, and the power of the laser beam emitted from the AOM 18 by this noise at the time of non-recording is so reduced that it can be ignored.

Filed: 1989-10-20
Abstract: PURPOSE:To display a color reproduced picture to meet the hue of a video signal when the video signal has the prescribed hue by changing this prescribed hue in a color demodulated signal. CONSTITUTION:As for the circuit elements of an amplifier 21B and an adder 22B for a color difference signal B-Y as well as the amplifier 21G and the adder 22G for the color difference signal G-Y, voltage sources V3, V4 are set at special values so as to have respective gains (b), (a). Accordingly, when the hue of green color is detected in a hue detection circuit 4, the amplitudes of the color difference signals R-Y, B-Y, G-Y from a color demodulation circuit 1 are corrected according to its detection signal value. Thus, the color difference signal to be supplied to a CRT drive circuit 3 becomes the color difference signal in which the hue of the green color on an axis R-Y/B-Y is changed, and a characteristic in which the hue of flesh color is less and in addition, the color reproducibility of the green color is good can be obtained, and optimum color reproduction becomes possible.

Title: Radio receiver
Inventor: NAKAZAWA SHOGO
IPC: H04B1/10
Filed: 1994-11-08
Abstract: PURPOSE: To effectively suppress an interference wave without attenuating a desired wave signal more than needed even in the state of the existence of the strong interference wave by limiting the signal amplification factor of an amplifier for RF detection small when the desired wave signal is extremely small. CONSTITUTION: The amplification factor of an amplifier 11 for RF detection is varied corresponding to the output level of an IF detector 12 for detecting an intermediate frequency (IF) signal level so that the amplification factor of the amplifier 11 for RF detection can be enlarged when the output of the IF detector 12 is large but can be reduced when the output of the IF detector 12 is small. Therefore, when receiving the weak desired wave signal on the condition of the strong interference wave, the loop gain of AGC including the amplifier 11 for RF detection is lowered, the attenuation degree of an input signal due to an attenuator 2 is reduced, and the level of the desired wave signal is kept almost at the original level. On the other hand, the interference wave is suppressed as much as possible by the selection characteristics of an RF tuner 4.

Abstract: PURPOSE: To measure the pH value of unknown electrolyte solution by subtracting the value obtained by multiplying the signal difference of pH signals of second and first indicators by valence coefficient from the pH value measured at the first indicator by using a specific formula. CONSTITUTION: The value obtained by multiplying the signal difference of pH signals of second indicator 12 (N) and a fluorophotometer F2 formed by a subtracting unit D2 and first indicator 11 by valence coefficient WF is subtracted from the pH signal of solution L measured by using the first indicator 11 (X) and a fluorophotometer F1 by a subtracting unit D3 . That is, the actual pH value is obtained by a formula I [where pH' (N) = crowned pH (N), pH' (X) = crowned pH (X), pH = actual pH]. In this case, the coefficient WF has the valence of formula II [where W = valance], and the generated signal is sent to an indicating unit A2 . Thus, the pH value of unknown electrolyte solution can be measured.
