Title: Inter-slice interpolating method of slice image
Inventor: KAKISHIMA HIROYUKI
IPC: G06T15/08
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain an image that does not make an artifact by performing threshold processing of an interpolation image with inherent threshold and eliminating the shape difference of upper and lower slice images. SOLUTION: An appropriate threshold to binarize an image is decided in order to extract a remarked area from the input images 1 and 2 of slice numbers i and i+1 before carrying out interpolation processing. The ratio of the sum total of pixel value that is threshold or more to the sum total of full pixel values is separately calculated about the upper and lower slice images 1 and 2. A predictive value is calculated about the ratio of sum total of pixel value that is inherent threshold or more to the sum total of full pixel values in an interpolation image 3 by performing linear interpolation of the ratio of the pixel value with the interval ratio between slices. The inherent threshold of the image 3 is decided based on the predictive value of the ratio of the pixel value.  In this way, appropriate value that corresponds to the distance ratio of slice intervals is decided by deciding the inherent value of the image 3.

Title: Spectrophotometer
Inventor: MURAKOSHI TAKEO
IPC: G01N21/27
Filed: 1990-04-06
Abstract: PURPOSE:To prevent the overlapping of the reflected light from a window and the reflected light from a sample from occurring and to measure reflectivity accurately by inclining the input/output windows of a tightly closed container containing the sample with respect to the incident direction of the sample light. CONSTITUTION:Sample light Bs is inputted into an incident window 12 of a cryostat 15 through a plane mirror 10 and a spherical mirror 11. The light which is reflected from a sample 13 and the mirrors 16' and 17' is inputted into a lens 18, and the amount of the light is measured. When the light Bs is inputted into the window 12 at a small angle, the light reflected from the window 12 and the light reflected from the sample are overlapped, and the error when a material having a low reflectivity is measured becomes large. Therefore, the window 12 of the cryostat 15 is inclined so that the reflected light from the window is not overlapped with the reflected light from the sample 13. In this way, the effect of the reflection of the measured light from the incident window is eliminated, and the accurate reflectivity can be measured.

Title: Exhaust gas cleaner for internal combustion engine
Inventor: MIURA MOTOHISA
IPC: F02D37/00
Filed: 1978-07-25
Abstract: PURPOSE: To prevent the build up of deposites or the like in the path by feeding recirculated exhaust gas and air to be fed to the suction system at deceleration through a common path.  
     CONSTITUTION: In the normal operation, an EGR valve 10 communicates recirculating paths to allow the exhaust to be recirculated to a suction pipe. With the decelerating operation, the rise in the suction negative pressure yields a difference in pressure between two chambers 302 and 303 of a deceleration control valve 30. While the difference exceeds a given level, a diaphragm 301 and a valve body 307 moves up against a spring 305 to open the opening 16a. Consequently, air is inducted to the suction pipe 3 through the opening 16a, a filter 308, an opening 16a and a path 6b to reduce CO and HC at the deceleration. As the primary air passes through a path 6b, it blows away deposites and condensed water of the exhaust gas accumulated on a shaft 14 of the EGR valve 10 and in the path 6b. In this manner, they are introduced to the suction pipe 3.
