Title: Detecting method for gas using superparticulate gas sensor
Inventor: ABE ATSUSHI
IPC: G01N27/12
Filed: 1980-12-05
Abstract: PURPOSE:To eliminate ununiformity of the sensitivity of the super-particulate gas sensor by detecting gas from the ratio of the resistance value in the absence of the gas to be detected to the resistance value in the presence of the gas to be detected. CONSTITUTION:The superparticulate gas sensor is constituted by providing an SiO2 film 7 on the surface of a p type silicon substrate 1, by providing electrodes 4', 4'' and 4''' on the surface of the film and by forming a superparticulate gas sensing film 5 on the top of the electrodes. As the thickness of this gas sensing film 5 is increased, an electric resistance value RO in the air where no gas to be detected is present is reduced. On the other hand, when the ratio of  the above value to an electric resistance value RG in the presence of the gas to  be detected is taken, the value thereof is fixed irrespective of inequality of RO.

Title: Pressure detector of internal combustion engine
Inventor: OOTSUKA YOSHINORI
IPC: G01L23/10
Filed: 1982-10-02
Abstract: PURPOSE:To obtain a good reproducibility of a pressure wave form and a complete seal under high pressure and to prevent a deterioration of the piezoelectric element by welding a diaphragm to a combustion chamber of an internal combustion engine or a housing of an implement attached thereto. CONSTITUTION:A combustion pressure in a cylinder is transmitted through pressure conduits 81c, 81d from a pocket part 84 of plug and arrives at the diaphragm 1 of a pressure detector A. The combustion pressure acts directly to the piezoelectric elements 21, 22 through the diaphragm 1, and a differential wave form of the pressure wave form appears at an electrode 32 for output. At that time, since the diaphragm 1 is fixed firmly by welding to a plug housing 81, the seal under high temp. and pressure becomes complete, and the deterioration of the piezoelectric element due to the incomplete sealing is eliminated. Since the combustion pressure acts directly to the diaphragm 1, the reproducibility of the pressure wave form is good. Since a preload is set to the elements 21, 22 by utilizing a spring property of the diaphragm 1, the structure is compact.
