Title: Color image reading element
Inventor: KAWASHIMA IKUE
IPC: G02B6/00
Filed: 1991-05-07
Abstract: PURPOSE:To obtain waveguide type image reading element with a simple confiquration, high mass-productivity, and high color correspondence by internally providing a color separation filter in photo waveguide optical transmission light path. CONSTITUTION:A waveguide type image reading element provided with a substrate 1, photo wave guide 2, transparent electrode 4, photoelectric converting element 5, and upper electrode 6 is formed by thin film process. In the photo wave guide 2, a groove is engraved, a color separation filter 7a is inserted in the groove to stick them by using adhesive, etc. Color separation filter is provided in the photo wave guide 2 one by one so that color filters which can transmit different colors as red, green, and blue, red, green, and blue lights in this order are inserted in each photo wave guide. Thus, by internally installing color separation filters in the photo wave guide 2, color correspondence image reading element is formed. Further, if the optical waveguide 2 is used as it is without cutting it in the middle, a black-white correspondence image reading element can be obtained. Accordingly, in the thin film process, since it is not necessary to discriminate both color image reading element and monochromatic image reading elements, this method is suitable for mass-production.

Abstract: PURPOSE:To improve the accuracy to estimate the amount of particulates to be collected by estimating the amount of particulates to be collected based on the corrected pressure loss by correcting the pressure loss of the filter by means of the engine speed and the intake air pressure loss. CONSTITUTION:An upstream pressure sensor 7 to detect the exhaust pressure, a temperature sensor 6, a heater 11, a filter 2 and a downstream pressure sensor 17 to detect the downstream pressure of the filter are arranged. A controller 8 is provided, the corrected pressure loss where the pressure loss of the filter 2 is corrected by the engine speed and the intake air pressure loss is obtained, and the particulate collection amount of the filter 2 is presumed based on this corrected pressure loss. When the downstream pressure of the filter 2 is deemed to be approximately constant, or close to the atmospheric pressure, the pressure loss of the filter 2 can be replaced with the upstream pressure of the filter. This constitution allows the accurate particulate collection amount to be estimated.
