Title: On-vehicle image processor
Inventor: YABE SANAE
IPC: G01B11/00
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent wrong information from being outputted in the case of abnormality by detecting abnormality of an image processing circuit, according to binarized data on a test pattern passed through the image processing circuit. SOLUTION: When a switching means 21 selects a switching input terminal 21b, in response to a switching signal E from a CPU 3A, the image processing circuit 13 performs an edge process for a test pattern image and performs a binarizing process for the edge-extracted image to find a binary image of the test pattern T. A circuit abnormality detecting means 16 in the CPU 3A detects the projection value (number of edge pixels) of the found binary image. The projection value is found from the total sum of pixel values of the binary image. The found projection value is compared with a previously set criterion (specific number of pixels), and it is decided that the image processing circuit 13 is abnormal, if the projection value is different from the criterion, exceeding a permissible range.

Abstract: PURPOSE:To converge a room temperature into a set in a short time temperature when an external disturbance (such as a variation in room temperature caused by opening or closing of a door) occurs. CONSTITUTION:An indoor controlling micro-computer 4 calculates a difference (a deviation) between a set temperature set by a remote controller 1 and an indoor air temperature detected by a room temperature thermistor 2, calculates a variation gradient of the indoor air temperature and determines an operating frequency of a compressor 7 in reference to these data.

Title: Production of low-grade electrical steel plate
Inventor: ASAI TOORU
IPC: B21B3/00
Filed: 1981-08-29
Abstract: PURPOSE:To obtain a low-grade electrical steel plate which is easy to grow crystal grains in stress relief annealing and has an excellent blanking property by regulating C, Si, Mn, P, S, Al and passing through the plate at specific temp. and tensile force after hot and cold rolling. CONSTITUTION:After the steel of <=0.10% C, <=0.3% Si, <0.30% Mn, <0.08% P, <=0.05% S, <=0.005% Al is hot rolled, the steel plate heated at temp. above 400 deg.C and below temp. of recrystallization in a continuous annealing furnace and is subjected to recovery annealing under >=0.35kg/mm.<2> tension. Here, Mn, and P can be economized because the hardness of steel is regulated mainly by the recovery annealing. If Al more than the limits is in corporated, it hampers the growth of crystal grains in stress relief annealing. The temp. for the recovery annealing below the lower limit has no recovery effect, makes softening of the steel strip insufficient and does not contribute to the improvement in its flatness. In excess of the upper limit, the hardness of the steel strip decreases considerably from optimum blaking hardness. If the tension during the annealing is lower than the lower limit, the function of improving the flatness of the steel strip is low.
