Title: Constant voltage circuit
Inventor: MATSUZAKI YUICHI
IPC: H03F3/45
Filed: 1994-08-22
Abstract: PURPOSE:To prevent the absolute value of the output voltage of a constant voltage circuit from dropping in absolute value even when the circuit is used while an integrated circuit is exposed to light by adding an optical detecting means in the constant voltage circuit. CONSTITUTION:When a constant voltage circuit is exposed to light, the light leak currents and bias currents of optical detection diodes reach values of nearly the same order, the optical detection diode 13 draws the potential at a point B toward VDD and the optical detection diode 14 draws the potential at a point C toward VDD. Through this operation, the potential at the point C becomes closer to VDD than at the time when not exposed to light and the potential at the point D is approximated to VSS, so that the absolute value of a voltage developed between VDD and the point D becomes equal to or larger when exposed to light than when not exposed to light. This circuit, therefore, operates as well as when no light shines.

Title: Extracting device for image feature
Inventor: KOIKE YOSHIMASA
IPC: G06T7/00
Filed: 1994-08-22
Abstract: PURPOSE: To quickly extract an image feature to be used for discriminating an object out of an input image in which a ghost resembling the object but having shape beyond a range is contained in addition to an objective partial image having the shape within the specified range. CONSTITUTION: In a pointer array 4, pointers corresponding one to one to each picture element of the input image are arranged. A sphere operating means 3 selects the pointer arranged in a line at equal intervals from the pointer array 4, and rewrites a sphere information table 5 by the selected pointer, and writes the coordinate of initial arrangement in this line, and investigates whether the pointer of the pointer array 4 is a free pointer or not gradually in order from an upper left part to a lower right part, and in the case that it is not the free pointer, it determines the movement/stoppage of a sphere by referring to the distribution of a picture element value in the circumference of the corresponding coordinate of an image storage means 2 and the direction of a gravity field.  If the pointer of a moving destination is not free, it writes the pointer of a former position in the column of the pointer of the line the pointer of the moving destination shows, and makes the pointer of the former position the free pointer.

Filed: 1984-09-21
Abstract: PURPOSE:To certainly discriminate defectives of lead frame having completed cleaning by converting existence or not existence of burrs or deffusions of lead portion to a digital value and then comparing it with the reference values. CONSTITUTION:Position A is determined corresponding to pulse N1, position B to pulse N2 and position C t pulse N3, desired picture of A-C is scanned within an image sensor 6 and it is converted from analog to digital value and it is stored in a RAM memory element 10. On the other hand, waveforms at the reference positions A-C (of good products from which burrs are eliminated are converted to digital from analog and such value is once stored in the ROM memory element 12. The stored value is compared with that of said RAM10. If there are burrs or damage D in the position C, the point of 0 obviously increases by one in the output D from the image sensor 6. As explained above, when difference of numerals is within a constant value, it is defined as 0 and it is larger than such value, it is defined as 1. When a number of 1's is larger than a constant value, it means that the burrs are not sufficiently eliminated. In such a case, a package is removed from the line automatically by sending a signal to the CPU.
