Abstract: PURPOSE:To analyze existence of abnormality in an EGR device without generating shock caused by decrease in engine rotational speed. CONSTITUTION:An EGR valve 6 and a torque variation means, for example idling rotational speed control(ISC) valve 4 are opened to specified openings, and the engine rotational speed Ne is compared with its specified value and then trouble is diagnosed when it becomes stable.

Title: Original inclination detector
Inventor: OSUMI JUNICHI
IPC: G06T1/00
Filed: 1988-12-12
Abstract: PURPOSE:To rapidly detect the inclination of an original by a simple constitution by finding out the minimum value of white runs in an image at a prescribed interval and finding out the end part of the image from the dots to detect the inclination of the original image. CONSTITUTION:White runs in each scanning line are measured by a white run measuring part 11, the origin is divided in each prescribed scanning lines by an image end part point extracting part 12 and the position of the scanning line having the minimum white run and its white run are found out to fix an image end part point. An image end part line extracting part 14 extracts a straight line capable of most effectively connecting the end part points of the image as an image end part line and an original inclination calculating part 15 calculates an angle theta between a vertical line and the image end part line. Since the minimum value of white runs in the image is found out at the prescribed interval and the end part of the image is found out from the dots to detect the inclination theta of the original image, complex processing requiring much time is not required as compared to an ordinary method and the original inclination is rapidly detected by the simple constitution.

Title: Vibration-isolation construction using stacked talc sliding layer and vibration-mitigating laminated rubber
Inventor: ITO YASUO
IPC: E04H9/02
Filed: 1994-11-10
Abstract: PURPOSE: To improve vibration resistance by stacking a stainless steel plate, vibration-damping laminated rubber, and talc layer in such a manner that the rubber and talc layer are interposed between the stainless steel plates. CONSTITUTION: Since a stainless steel plate 1 is laid on a foundation 4 and a talc powder layer 2 is placed on the plate 1, very high sliding property is provided, whereby even if lateral waves of earthquake come, sliding property is repeatedly provided so that vibration energy can be consumed and vibration to be transmitted to a building 5 can be reduced. Next, the building 5 can be held in a relatively stable state due to its own weight and force of inertia against the vibration of an earthquake. Further since a vibration-damping laminated rubber layer 3 has non-vibratory property against violent shaking of vertical waves of earthquake and has also flexibility, vibration of earthquake is damped and transmitted to the building.  Consequently, heavy pressure of the building and severe friction produced by vibration of earthquake can be born so that excellent vibration-damping function can be produced.
