Title: Input and output port
Inventor: SATOU IKUO
IPC: G06F13/40
Filed: 1982-09-29
Abstract: PURPOSE:To execute effectively maintenance by interrupting quickly connection with a bus line at the time of abnormality of a power source, by a photoelectric coupler connected to a power source line, in an input/output port connected to the power source line. CONSTITUTION:When a power source VDD is normal, LEDs 36, 38 and 40 emit light, phototransistors TR32, 30 and 34 become a conductive state, and data can be sent and received between a bus line 12 and an I/O port 14. On the contrary, if a fuse 20 is fused due to a short circuit of the power source VDD, etc., the LEDs 36, 38 and 40 do not emit light, therefore, the TRs 32, 30 and 34 become a nonconductive state. As a result, tri-state buffers 16, 18 are cut off electrically from the bus line. As a result, the I/O port can be replaced in a state that the power source line is in electic conduction.

Title: Detecting method for feature point position and straight line direction on boundary line
Inventor: NAKAYAMA NORIAKI
IPC: G06T7/60
Filed: 1990-06-29
Abstract: PURPOSE:To inspect the uniformity of a pattern in respect of the picture of a metallographic structure cross section, etc., by detecting the position of a feature point and the directional relation of each straight line at the time when two areas different in their brightness are adjacent to each other as considering each straight line extending in two different direction from the feature point to be a boundary by picture processing. CONSTITUTION:A window W is generated in a fixed picture including the feature point P in a field of view so that one of the straight lines penetrates it in parallel with its one side, and at every place at the time when this generated window is moved in parallel with one of the straight line, a projection upon a first side perpendicular to the moving direction of the window is taken. Then, the coordinate of the changing point of the maximum value or the minimum value of this projection in relation to the first side of the window is determined for every place, and the position of the feature point is detected based on two pieces, at least, of this coordinate. Besides, the projection upon the second side of the window perpendicular to the first side is taken for every place, and the directional relation of each straight line is detected based on the increasing or decreasing tendency of this projection value. Thus, this method can be utilized for the automatic inspection of the uniformity of the pattern in respect of the picture of textiles or the metallographic structure cross section, etc.
