Title: Image pickup device
Inventor: SHIIBA ITARU
IPC: H04N9/07
Filed: 1982-06-04
Abstract: PURPOSE:To improve the luminance signals of a single-tube or single-plate image pickup device by increasing the minimum transmittivity of a filter from 20% to 90%. CONSTITUTION:The transmittivity characteristics of conventional color filters of blue, green, and red are shown by 1, 2, and 3 and those of this invention are shown by 4, 5, and 6. The blue filter 4, for example, has 40% minimum transmittivity and a slanting-line part 7 shows an increment of the luminance signal. However, the luminance signal to light with equal energy increases up to about 80% over the entire 400-700nm wavelength range as compared with the conventional blue filter 1. Since light with an 8 luminosity factor is effective to an image pickup device, the luminance signal of about 30% increases. Similarly, green filter and red filter luminance signals also increase by about 30%, so the total increment of the luminance signals is about 90%. Its upper limit depends upon the S/N ratio of chroma required by a camera. The lower limit is a limit where effect is recognized; and the former is limited to 90% and the latter is limitted to 20%.

Filed: 1990-04-11
Abstract: PURPOSE:To achieve a measurement at a low cost with a sample apparatus by obtaining a decrease rate of an output range of a downstream side air/fuel ratio sensor with respect to an output range of an upstream side air/fuel ratio sensor to measure an average purifying rate of a catalyst. CONSTITUTION:A decrease rate of an output range of a downstream side sensor 5 is determined under various purifying rates beforehand with respect to an output range of an upstream side sensor 4 to be for a calibration curve. The purifying rates are determined by sampling exhaust gases at two points to measure amounts of components (HC. CO and NOx) with analyzers. As a result, a better linear relationship between an output decrease rate and an average purifying rate is obtained almost in the entire range of the purifying rate. Thus, a purifying rate of a catalyst can be found out by clarifying the decrease rate. Especially, in all ranges of purifying the decrease rate. Especially, in all ranges of purifying, a purifying rate of the catalyst can be learned accurately. Moreover, a specified value of an output range decrease rate is defined as degrading timing.
