Title: Detection of catalyst having inferior activity
Inventor: ITSUPONMATSU MASAMICHI
IPC: G01N23/227
Filed: 1982-12-24
Abstract: PURPOSE:To detect easily a catalyst having inferior activity by analyzing the noble metal catalyst deposited on a carrier of alumina, titanium dioxide, zirconia, etc. by a photoelectric spectrochemical method. CONSTITUTION:Light of X-rays, etc. is applied on a catalyst specimen formed by depositing noble metal such as ruthenium, platinum, rhodium, palladium, nickel or the like on a carrier of alumina, titanium dioxide, silica-alumina, zirconia, etc. and the energy distribution of the electron released from the specimen by a photoelectric effect is measured. Whether the activity of the catalyst is inferior or not is determined by identifying the presence of catalyst activity if the peak of the active metal in the X-ray photoelectron spectra is in the same position as the position of 0 valency or is shifted to an oxidation side and by rejecting the catalyst activity when said peak is shifted to a reduction side. The inferior activity occurring in the strong mutual effect of the catalyst-carrier is extremely easily detected according to such detecting method.

Title: Method and device for zero-point temperature compensation of flow meter
Inventor: OTSUKA MASAYOSHI
IPC: G01L9/00
Filed: 1986-10-02
Abstract: PURPOSE:To perform zero-point temperature compensation only by a diffusion type semiconductor pressure sensor by changing the combination of four diffusion gauge resistances and constituting the 2nd bridge circuit which varies in output only with the temperature of fluid, and subtracting the output of the 2nd bridge circuit from the output of the 1st bridge circuit. CONSTITUTION:In the 1st bridge circuit on a silicon substrate, R1 and R4 are resistances varying in resistance value with the speed of the fluid and R2 and R3 are resistances varying in resistance value with the speed of the fluid. Here, when the temperature of the fluid is constant, an output Vout corresponding to the flow of the fluid is DELTAR/R.VB. Then, the wiring of the resistances R3 and R4 is changed to constitute the 2nd bridge circuit and then the output Vout becomes 0. Namely, the output Vout of the 2nd bridge circuit becomes irrelevant to pressure and varies only with the temperature of the fluid. Here, when the difference between a pressure-side bridge unbalance signal and a blind side bridge unbalance signal becomes constant, the output level does not varies regardless of variation in temperature and the zero-point temperature compensation is performed.
