Title: Method for controlling travel of self-traveling working vehicle
Inventor: SOGAWA TAKAYUKI
IPC: G06T7/00
Filed: 1994-02-09
Abstract: PURPOSE:To improve the controlling of the travel of a self-traveling working vehicle by binary-coding a picture image and subsequently computing an accurate boundary- approximating straight line from the binary-coded picture image, when the boundary is detected from the imaged picture image for controlling the travel of the self- traveling working vehicle along the boundary between a worked target region and a non-worked target region. CONSTITUTION:A slice level for binary-coding a picture image is set to an average value near to the maximum value of changed brightness quantities in the picture image region, e.g. to the about 50% of the average value of 10 data in the higher rank, and picture elements exceeding the slice level are extracted from a differential value picture image. A straight line approximating a working boundary is computed by the Hough transformation of the binary picture image. Thereby, the fluctuation of the slice level due to the changes of the ratio of a worked target region to a non- worked target region, which are imaged on the picture such as a case wherein a slice level is computed on the average value of the whole picture, can be prevented, and the picture image can surely be binary-coded. The affection of noises can be reduced more than a case in which a straight line is computed by a method of least square, etc.

Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a field-effect transistor, which prevents generation of stresses in the semiconductor film, by preparing porous regions selectively on a silicon substrate on its surface layer region, by forming compound semiconductor films on a silicon substrate, by removing the semiconductor films on the porous regions, by forming the field-effect transistor using the remaining part of the semiconductor films, and by impregnating a metal into the porous regions.

Then, compound semiconductor films 8, 9 and 10 are grown heteroepitaxially. Subsequently, the porous silicon regions are replaced with a metal such as Cu, so that only the porous Si regions 6 on the substrate 1 are replaced with the metal, keeping it as porous, while the silicon bridge is left unchanged. Since the compound semiconductor films are grown after the porous regions are formed in the surface layer region of the silicon substrate and the transistor is formed by using the compound semiconductor films on regions other than the porous regions, the stresses caused by the difference in lattice constant between the silicon substrate and the GaAs layers grown on the silicon substrate can be relaxed.
