Patent JP-H10303642-A (JP)
Title: Oscillator
Inventor: OKUMURA MASAO
IPC: H03B5/12
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of higher harmonic components by providing a 1st amplifier whose output signal varies up to a nonlinear area for an input signal and a 2nd amplifier whose output signal varies in a linear area, mixing the output signals of the 1st and 2nd amplifiers, and selecting the frequencies of the mixed output signals. SOLUTION: The gain of the 1st differential amplifier 10 is set larger than the gain of the 2nd differential amplifier 11 and the level of the output signal of the 1st differential amplifier 10 is set, for example, one tenth as high as that of the 2nd differential amplifier 11. Further, the gain of the 2nd differential amplifier is a little smaller than 1 and its deficiency is compensated by the 1st differential amplifier 10. The output signals of the 1st differential amplifier 10 and 2nd differential amplifiers are added by using a load resistance as a common load and inputted to a BPF 2 which selects a frequency. Consequently, the influence of a component having distortion in terms of level becomes small to greatly reduce the distortion quantity.

Filed: 1995-05-08
Abstract: PURPOSE: To obtain a light-position detection apparatus in which quantity of signal light is corrected and whose accuracy is high by consisting a division function of a simple circuit. CONSTITUTION: Terminals on respective one sides of photodiodes PD01 to PD10 are connected to connection points at a resistor row in which a plurality of resistors R101 to R110 have been connected in series, and a reverse bias voltage is applied to the photodiodes PD01 to PD10 . When light is made incident on the photodiodes PD01 to PD10 , a current at a current value corresponding to the intensity of the light flows in a route corresponding to positions of the photodiodes. A signal which corresponds to the current value is divided into many stages by another resistor row, and potentials at the respective divided stages and signals which are dependent on positions and current values of the photodiodes on which the light is incident are compared by comparators COMP01 to COMP10 regarding their magnitude, and a digital amount which represents the light incident position is output.  In addition, the digital amount is converted into an analog value by a resistor R22 which is connected to output terminals of the comparators COMP01 to COMP10 and by a constant voltage source 51.

Abstract: PROBLEM TO BE SOLVED: To easily and highly accurately color-reproduce an optional color without the need of much preparation man-hour. SOLUTION: For the respective colors of RGB, after plural signal values are set, color patches are displayed (110-114), the colors of the respective color patches are measured and the tristimulus values (Xml , Yml , Zml ) of the colors of the respective color patches are obtained (116).

IPC: H04N7/18
Filed: 1992-04-28
Abstract: PURPOSE:To correct the gradations of X-ray image data, obtained by reading an X-ray photograph, in consideration of characteristics of an X-ray film. CONSTITUTION:The maximum density Dmax and minimum density Dmin of a main subject are detected from the image data obtained by reading the X-ray photograph. Then the density Dmax and density Dmin are converted into relative X-ray dosages Emax and Emin by using the characteristic curve D=f1(E) of the X-ray film. Optimum density values Dcmax and Dcmin, on the other hand, are converted into relative X-ray doses Ecmax and Ecmin by the characteristic curve D=f1(E). Here a conversion function D=f1(E) for the relative X-ray doses is set by using the values of the relative X-ray doses. Then the conversion function f2(E) is regenerated into a dimensional conversion function F(D)=f1(f2(f1<-1>(D)) for the density data by using the characteristic curve D=f1(E) and this is used as a gradation conversion function of the X-ray image data.
