Title: Exhaust gas circulation device at incinerator
Inventor: IMAIZUMI SUSUMU
IPC: F23G5/00
Filed: 1985-02-06
Abstract: PURPOSE:To enable to circulate a part of exhaust gas into an incinerator by installing a circulation duct for exhaust gas which is branched off from a by- path duct and is connected to hoppers under burning fire grate, hoppers under after-burning fire grate, a cooling air inlet of the incinerator and an upper part of a main ash chute. CONSTITUTION:During operation, reduction of NOx concentration in fuel exhaust gas is achieved by turning down a damper 17 in a primary duct 19 and reducing wind volume from a forced draft blower 16. On the other hand, oxygen in fresh air from a blower 49 controlling incinerator temp. increases the oxygen concentration in the exhaust gas and as a result, NOx concentration increases. By closing a damper 47 in a by-path duct 46 and opening damper 48 at the same time, a part of exhaust gas with low O2 concentration which flows in a secondary exhaust gas duct 42 from an electric precipitator 41 is enabled to flow reversely in the by-path duct 46 before going into a stack 45 and then is enabled to flow in an exhaust gas circulation duct 52. The exhaust gas is supplied and circulated to hoppers 12, 13, 14 corresponding to a burning fire grate 5 and an after-burning fire grate 6 via exhaust supply ducts 55, 56, 57 and burns waste after being mixed with a fresh air.

Title: Separating circuit for luminance/color signals
Inventor: NAKANE SHUHEI
IPC: H04N9/64
Filed: 1994-02-21
Abstract: PURPOSE:To separate the luminance signal from the color signal by subjecting the input video signal to Y/C division, outputting the sum of the signals Y and C or the signal C according to whether an uncorrelation circuit detects the uncorrelation or not, and adding the input signal to the negative signal C through a phase adjustment circuit. CONSTITUTION:A video signal in the PAL system is inputted through an input terminal Vin to a band-pass circuit 11 and a phase adjustment circuit 7. The output signal of the circuit 11 is outputted by separating it into a luminance signal Y and a color signal C. An uncorrelation detection circuit 13 takes in the signals C and Y by a divider 6 and performs the pulse processing of the absolute value detected by absolute value detection circuits 20 and 23 by pulse processing circuits 21 and 24. Detection circuits 22 and 25 detect the uncorrelation part of the signals C and Y, adds 26 them to generate a switching signal CTRL which is outputted to a switch 15. When the circuit 13 detects the uncorrelation, the switch 15 is closed to output the color signal from the terminal COUT by adding the signals Y and C by the use of the adder 16. When the circuit 13 detects no uncorrelation, the signal C alone is outputted. On the other hand, the signal C of the negative code is added by the use of an adder 17 to the output of the circuit 7 and the luminance signal is outputted from a terminal YOUT.

Furthermore, interface peeling resistance in soldering can perfectly be prevented without influencing highly on the lowering of the dielectric constant by suitably adding Zn to the alloy. In this way, the alloy is suitable for working a lead frame into copper alloy.

Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To expand a beam scannable range by providing a control means or the like which respectively switches the phase-shift quantity of 1st and 2nd phase shifters to specific angular ranges and controls left or right handed circularly polarized wave to be radiated from a radiation element. SOLUTION: A control circuit gives a 1st control signal s41 to a phase-shift circuit 12a constituting a 1st phase shifter 12, a 2nd control signal s42 is similarly given to a phase shift circuit 13 constituting a 2nd phase shifter, and the states of the circuits 12a and 13 are respectively controlled by the signals s41 and s42. When the operation of the two circuits 12a and 13 is controlled in this way, the radiation of a radiation element 11 can respectively be switched to 0 deg. left handed circularly polarized wave, 180 deg. left handed circularly polarized wave, 0 deg. right handed circularly polarized wave, 180 deg. right handed circularly polarized wave. Then, even though three phase shifters are needed in the conventional practice, only two phase shifters are needed so that the unit can be made small-sized and a beam scannable range can be expanded due to this miniaturization.
