Title: Code conversion system of digital video signal
Inventor: EGUCHI TAKEO
IPC: H04N9/804
Filed: 1983-04-11
Abstract: PURPOSE:To obtain the code signal of less DC component by dividing a main area which is obtained by projecting Y, R-Y, and B-Y code spaces to Y, R-Y and Y, B-Y coordinate systems when Y, R, and B are denoted as the digital luminance and red and blue signals respectively, to a subarea on a basis of an intermediate value based on the Y axes and assigning code signals, where absolute values of the code word disparity sum are low, to the subareas nearer to the centers of main areas. CONSTITUTION:The main areas Tm(R-Y) and Tm(B-Y) and Tm(B-Y) obtained by projecting Y, R-Y, and B-Y code spaces to coordinate systems where Y, R-Y and Y, B-Y coordinate systems are expressed digitally are divided to subareas (a)-(d) and a'-d' on a basis of intermediate values l0(R-Y) and l0(B-Y) based on the Y axes, and the code signals where the absolute values of the code word disparity sum (CDS) are low are assigned to the subareas in order from subareas (b), b', (c), and c' nearest to the centers of the main areas. CDSs of both axes are divided by the unit of one in a range of -8-+ or -0-+8. Since a color difference signal is taken into consideration in accordance with the level of the luminance signal Y to vary an 8-8 map adaptively, the CDS of the color difference signal enters in a range of -2-+2, and the code signal of less DC or low-band component is obtained.

Title: Power supply for power amplifier of travelling wave tube
Inventor: IWANAMI YOSHITOMO
IPC: H01J23/34
Filed: 1994-03-31
Abstract: PURPOSE:To restrain the abnormal rise of output voltage at the time of a startup by causing an anode electrode power supply to generate anode voltage via the addition of DC voltage generated therein to collector voltage. CONSTITUTION:A power supply 4 for a travelling wave tube power amplifier is formed out of an anode electrode power supply 1, a helix electrode power supply 2 and a collector electrode power supply 3. The anode electrode power supply 1 adds DC voltage generated therein to collector voltage 103, thereby generating anode voltage 101. In this case, the anode voltage 101 is higher than cathode potential 100. Thus, a certain amount of electron beams flows in a travelling wave tube 5, even if the power supply 1 does not start up. The excessive rise of the output voltage (anode voltage 101, helix voltage 102 and collector voltage 103) of the power supply 4 can, therefore, be restrained.

IPC: B22D11/049
Filed: 1986-03-24
Abstract: PURPOSE:To improve the productivity of casting billet by pushing out cooling water brought into contact with the casting billet surface through gas flow toward the casting billet drawing direction. CONSTITUTION:A cooling cylinder 5 having cooling water injecting hole 6 and gas injecting hole 7 at an outlet side thereof is arranged to a hollow mold 1 with built-in exothermic body 2.
