Title: Catalytic combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23C99/00
Filed: 1987-03-16
Abstract: PURPOSE:To obtain safe and efficient catalytic combustion, burnt perfectly without any slip of fuel, highly efficient in the heat emission of radiation and never generating backfire phenomenon, by a method wherein a distributing pipe, dispersing and supplying the fuel between an air supplying unit and a catalyst layer, is arranged at the nearest place of the catalyst layer. CONSTITUTION:An air supplying tube 4 is arranged at the most upstream side, then, a fuel distributing pipe 2 and a catalyst layer 5 are arranged sequentially at the downstream side of the air supplying tube 4 while the distributing pipe 2 is positioned in the proximity of the catalyst layer 5. When ignition is effected by an ignitor 7, catalytic combustion is started around the upstream side of the catalyst layer 5 to heat the catalyst layer 5, whereby heat is emitted by radiation through a glass window 8. On the other hand, the relative ratio of fuel to air between the distributing tube 2 and the catalyst layer 5 has become a combustible concentration. However, no structure for fixing flame is provided and a space between the distributing pipe 2 and the catalyst layer 5 is very small; therefore, flame will never be formed and stable catalytic combustion is continued without any possibility of backfire. Further, there is no structure which reflects or absorbs heat between the upstream side main combustion surface of the catalyst layer 5 and the glass window 8 except the distributing pipe 2, thereby emitting heat efficiently by radiation. There is no slip of fuel in combustion exhaust gas, therefore, perfect combustion is effected in the catalyst layer 5.

Title: Stereo and monaural change-over device
Inventor: SHIMADA GIICHI
IPC: H04B1/16
Filed: 1980-05-08
Abstract: PURPOSE:To improve the rise during a change-over between the stereo and monaural modes, by using a means having a prescribed time constant when a change- over is carried out from the stereo mode to the monaural mode and vice versa. CONSTITUTION:For a stereo demodulator of PLL system, the output of a phase comparator 68 is supplied to a differential amplifier 118 via a low pass filter 70. When a forcible change-over signal from stereo to monaural mode is supplied to a stereo-monaural change-over circuit 86, a bias is applied to a terminal 146. Thus a switch 100 is turned on to instantaneously turn a voltage control oscillator 60 into an inactive state. At the same time, the stereo switch circuit is also turned off to prevent the occurrence of a pop noise. The bias is released when the monaural mode is changed to the stereo mode, and accordingly, the oscillator works instantaneously. However, the amplifier 118 is turned on after a lapse of the delay time of the filter 70.
