Title: Deciding device for quality
Inventor: FUJII TEIZOU
IPC: G01N21/89
Filed: 1982-02-24
Abstract: PURPOSE:To determine and self-decide the degree of a quality, by a method wherein a fluorescent lamp image, projected on a work, is detected by a camera, and the width of the image and the turbulence width of the edge of the image are automatically analyzed and decided by a picture processor. CONSTITUTION:An image 13 of a fluorescent lamp 6 projected on a work 9 is detected by a television camera 7, and is binary-coded into 2 colors of white and black by a picture processor 10. The processed image 14 is analyzed to detect a width W of the image 14 and a turbulence width D of the edge of the image 14. In case the work 9 is not lustrous, the image 13 is dim, and the width W of the image 14 narrows. In case there is a low undulation on the surface of the work 9 or the work 9 is lustrous but has a defect on the surface thereof, the width W widens owing to a scattering phenomenon. The influence by luster can not be separated from the influence by a defect merely by decision based on the width W. Then, if there is no flaw on the surface of the work 9, the edge part of the image 14 is straight, and thereby the width D is detected by a turbulence deciding mechanism 12 to conduct a decision, and it is decided that the less the width D is, the better the surface is.

Title: Actual steering angle controller for vehicle
Inventor: KAWABE TAKETOSHI
IPC: B62D7/14
Filed: 1987-02-10
Abstract: PURPOSE:To improve a response characteristic as well as to secure the extent of running stability, by installing a means which finds a rear-wheel actual steering desired value out of both desired and estimated values of a kinetic variable, and when the occurrence of a inverse response is expected, regulating a variation in rear-wheel actual steering angles. CONSTITUTION:On the basis of a deviation between the kinetic variable desired value M0' and the kinetic variable estimated value found by operational means 103 and 104, an operational means 105 finds a rear-wheel actual steering angle desired value. When this deviation is larger than the specified value, codes of both values M0' and M0'' are different and the occurrence of an inverse response is expected, a command value regulating device 106 outputs a rear- wheel actual steering angle command value, regulating the steering of rear wheels by a rear-wheel steering device 107. Therefore, even if a gain in the kinetic variable of lateral acceleration is heightened, the occurrence of the inverse response is preventable. Accordingly, the desired kinetic performance is securable upon securing the running stability of a vehicle while improving the extent of response capacity in the lateral acceleration.
