Title: Method of purifying nitrogen oxides in exhaust gas
Inventor: IIZUKA HIDEHIRO
IPC: B01J23/42
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To steadily and efficiently purify exhaust gas discharged in lean- burning combustion by using a catalyst in which Ti and Pt are deposited as active components on a porous carrier consisting of an inorganic oxide compound other than titania. SOLUTION: The nitrogen oxides in the exhaust gas discharged under a lean-burning combustion condition can be efficient reduced into nitrogen by using hydrocarbons and carbon monoxide as reduction agents. Also the hydrocarbons and carbon monoxide can be oxidized with the oxygen in the exhaust gas. Thus, the hydrocarbons and carbon monoxide can be treated. When the catalyst 3 contains Ti, Pt and Rd in the inorganic carrier, Rd, the catalyst has remarkably high catalyst activity under a stoichiometric operational condition. By mounting the catalyst 3 on an exhaust gas flow path 2 in the back stream of an internal-combustion engine 1, the nitrogen oxides can be considerably suppressed from being exhausted to the outside of the vehicle.

Title: Video signal discriminating device
Inventor: IKEDA NORINOBU
IPC: H04N9/80
Filed: 1991-04-30
Abstract: PURPOSE:To reduce erroneous discrimination to reproduce the picture of high quality by counting the frequency in repeat of a carrier wave in a prescribed blanking period and discriminating some carrier frequency based on the counted result. CONSTITUTION:The vertical blanking period is 20H period in the case of NTSC; and since the frequency variance of an FM luminance signal in this vertical blanking perios is small, discrimination error is reduced if the high band system and the standard system are discriminated in this period. That is, a magnitude comparator 7 receives a binarized signal only in the vertical blanking period by the operation of a gate circuit 8 and counts the frequency in going to high level 'H'. Since the frequency in 'H' of the reproduced RF signal recorded by the high band system is higher, recording in the high band system is discriminated when the counted value is larger than a preliminarily determined threshold. The demodulation gain of a demodulator 5 is switched based on the discrimination result of the magnitude comparator 7.
