Title: Eliminating circuit for dc offset voltage
Inventor: SASAKI KANEHITO
IPC: H03M1/10
Filed: 1986-05-30
Abstract: PURPOSE:To simplify the constitution of a eliminating circuit for DC offset voltage and also to eliminate the DC offset signal out of the analog input signal with no effect of the frequency of the analog input signal, by using an A/D converting circuit, an averaging circuit and a D/A converting circuit. CONSTITUTION:The analog input signal containing the DC offset signal is applied to an input terminal of a subtraction circuit 12 for subtraction and then converted into digital signal by an A/D converting circuit 13. This digital signal is averaged for a prescribed period by an averaging means 15 to obtain the digital signal equipment to the DC offset signal. Then the digital signal is converted into the analog signal by a D/A converting circuit 16 and applied to the other input terminal of the circuit 12 for subtraction. Then the analog signal which contains no DC offset signal is obtained from the analog input signal. AS a result, the arithmetic processing result is obtained with high accuracy.

Title: Color image processor
Inventor: TAKIGUCHI HIDEO
IPC: G06T5/00
Filed: 1986-05-30
Abstract: PURPOSE:To use efficiently the capacity of a color correcting processing table by executing the fine color correcting processing to the picture element having low saturation with the large number of the picture elements, and executing the coarse color correcting processing to an image having a high saturation with the small number of the picture elements. CONSTITUTION:At the front step of a color converting table 2, an address converting table 1 is equipped. When a color image signal is a luminance signal Y, and color difference signals R-Y and B-Y, luminance Y is not necessary for saturation, and therefore, the luminance Y is not inputted to the address converting table 1. The address converting table 1, is constituted of, for example, a ROM, etc., and a color difference signal comes to be the address input of the ROM. For the ROM, the data are stored in which dense quantization is executed to the part with the low saturation beforehand and coarse quantization is executed to the part with the high saturation, the function is quantization and comes to be the conversion of the address space. The output from the address converting table 1 is the converted address and color image signals R-Y' and B-Y' in which the value is changed.

Title: Electron gun for electron beam welding
Inventor: KITA HISANAO
IPC: B23K15/00
Filed: 1979-09-28
Abstract: PURPOSE: To prevent the occurrence of micro-arcing and arcing phenomena and form the defect-free weld zone by disposing plates each having a beam passage hole on the way of the beam passage of an electron gun for electron beam welding machines.  
     CONSTITUTION: The works 11 in a vacuum chamber 1 are melted by an electron beam 12 by an electron gun 8, and are thereby welded. In this case, the metal vapor produced by melting of the metals 11 to be welded and the gas contained in the metals 11 to be welded are released. These metal vapor and gas decrease the degree of vacuum in the electron gun 8, thereby causing the micro-arcing phenomenon by which the beam output is rapidly changed and the arcing phenomenon by which the beam is cut off, and thus producing defects such as dents 15, dropping 16 of molten metal, voids 17, etc. In order to prevent these defects, three plates 19 are disposed in the beam passage position of the front face of the metals 11 to be welded. The metal vapor and gas are captured between these plates 19, whereby the above- mentioned phenomena owing to the decrease in the degree of vacuum in the electron gun 8 is prevented from occuring and the weld bead surfaces are made into a defectfree state.
