Title: Production of combustible gas detecting element
Inventor: KUSANAGI SHIGEKAZU
IPC: G01N27/12
Filed: 1978-08-31
Abstract: PURPOSE: To improve the strength of detecting element, while requiring not sintering treatment at a high temperature, and to reduce the breakage of the element and the slackness of an electrode thereby to reduce the dispersion in the performance of the element by forming the element with a porous binder layer on its whole surface.  
     CONSTITUTION: The material powders, which are prepared by pulverizing a metal oxide such as SnO 2 , ZnO or γ-Fe 2 O 3 , are molded into a shape, in which a platinum electorde 1 has its upper portion embedded, and then sntered at a temperature of 600 to 1200°C thereby to prepare a gas sensitive element 2. To the dispersion, in which binder layer forming particles such as SiO 2  or AlO 3  are dispersed in  water, there is added a binder agent such as coloidal silica or alumina zol for binding binder layer forming particles. The gas sensitive element 2 is then dipped in  the dispersion thus prepared and is dried. The element 2 is then baked at a temperature of 300 to 800°C, which is lower than the sintering temperature, thereby to  prepare a binder layer 3. Thus, it is possible to produce a combustible gas detecting element A which is prepared by coating the gas sensitive element 2 with the  porous layer 3.

Abstract: PROBLEM TO BE SOLVED: To quickly attain automatic restoration of a system through the use of a preliminary transmission system even when one of transmission channels is interrupted by providing an abnormality discriminating unit which discriminates the interruption of a transmission signal or level abnormality for each channel. SOLUTION: When the interruption of an RF signal is detected by a certain abnormality decision unit 5, and an on-signal is outputted, the on-signal is inputted to an input channel discrimination port and an output channel discrimination port, and the input channel and output channel of a TV signal processor 1 in which abnormality is generated are determined from the channel number of the input channel discrimination port to which the on-signal is inputted and the output channel number. Based on this channel information, a CPU circuit 6 outputs a control signal to a TV tuner circuit 3 and a universal modulation circuit 4, allows the TV tuner circuit 3 to receive the signal of the interrupted channel, and allows the universal modulation circuit 4 to convert the output into the transmission signal of the interrupted channel.  Thus, broadcasting can be continued upon occurrence of an abnormality in a system under operation.

Below the central region F1, the line of intersection that the plane normal to the main meridian M-M' and the lens refracting surface assume is the nonlinear curve of which the value of the radius of curvature decreases as it goes further from the point of intersection with the main meridian. Even if there are large aberrations for the side parts F2, F3, there is less effect thereof and therefore the curves differing from that of the F1 are employed for these parts to decrease the aberrations of the near vision part N and the intermediate part P. A distinct vision area is the shaded range in the figure.
