Title: Image signal reception limiting device
Inventor: MATSUHASHI HISAHIRO
IPC: H04N5/44
Filed: 1992-04-08
Abstract: PURPOSE:To easily limit image reception without selecting receivers and installing positions by jamming inputted image signals so as to make the image reception difficult. CONSTITUTION:The inputted image signals enter through a buffer amplifier 21 to a signal input part 22. A program to limit the reception is inputted to a receiving means 24 by a remote controller 23, and a signal expressing the relevant program is converted to a control signal by a control means 41. According to this control signal, a jamming signal generating means (carrier generating part) 26 generates a jamming signal for jamming the image signals of the relevant program, and the jamming signal is added to the image signals by a signal adding part 22 and outputted to an image signal receiving means. Therefore, the relevant program generates a beat fault by the addition with the jamming signal and disables the reception. Thus, since this device makes the reception difficult by jamming the image signals inputted by a normal means, the device can be used without selecting receivers and installing positions.

Abstract: PURPOSE:To enable feedback control even within rich air-fuel ratio control area by providing an air-fuel ratio sensor on the lower side of an emission purifying catalyst, and performing air-fuel ratio feedback control through an air-fuel ratio sensor while supplying a predetermined amount of air to the upper side of the emission purifying catalyst. CONSTITUTION:When the amount of supplied fuel is set to rich air-fuel ratio, the air-fuel ratio of the total amount of air flow consisting of the amount of intake air flow and that of the shortage of air flow to the amount of supplied fuel is set to a predetermined one. In that case, CO, HC, etc., generated in exhaust by rich air-fuel ratio combustion when air supplied to an exhaust passage is allowed to pass through an emission purifying catalyst while being mixed with the exhaust are oxidized by O2 contained in the air and therefore the components of the exhaust on the lower side of the catalyst become roughly the same as those of exhaust generated by combustion at the predetermined air-fuel ratio. Therefore the output value of an air-fuel ratio sensor is held at a reverse level by a feedback control means in order for virtual air-fuel ratio determined by exhaust components to approximate the predetermined air-fuel ratio, thus performing feedback control to the set rich air-fuel ratio.
