Filed: 1992-12-22
Abstract: PURPOSE:To provide the pattern recognizing method and device which compares the pattern segmented from an image to be identified with a reference pattern and can shorten the time needed for collation of a frame pattern and the reference pattern. CONSTITUTION:When a frame pattern 3 is compared with a reference pattern 4, the collating position with the pattern 4 is moved by a space equal to plural picture elements.

Title: Insensitive circuit
Inventor: KAKO YUICHI
IPC: H02H7/18
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To shorten the insensitive time of an insensitive circuit by connecting the circuit to a charging circuit and a comparison input terminal and, when a detect signal returns to a normal state from an abnormal state, making a quick charging current to flow to the comparison input circuit only during the period until the charged voltage of a capacitor becomes a bias voltage. SOLUTION: A quick charging circuit 7 is connected to a charging circuit 4 and a comparison input terminal TP3 and, when a detect signal returns to a normal state from an abnormal state, a bipolar transistor Q1 is turned off by making the level of input signals lower than a detected level Vreg1 and setting the output of the input comparator COMP1 of an abnormality detecting circuit 3 at a low logical level. Under such a condition, the charging of a capacitor C1 is started by making a constant current I1 from a constantcurrent source IO1 flow to the charging circuit 4 side and supplying a charging current I1a to the input terminal TP3. At the same time, the capacitor C1 is quickly charged by making a current I1c amplified by means of the bipolar transistors Q11 and Q13 of the quick charging circuit 7 flow to the input terminal TP3.

Title: Leak inspection apparatus
Inventor: UCHIYAMA YOSHIFUMI
IPC: G01M3/26
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain a leak inspection apparatus in which a change in a zero point is corrected automatically and in which an always correct inspection can be maintained by a method wherein a zero-point change value which is stored in a zero-point-change storage means at a timing decided by an update decision means is updated to a zero-point change value detected at the timing. SOLUTION: A differential pressure value which is generated due to the internal-volume difference between the side of a work capsule 6A and the side of a master capsule 6B in a state that nondefectives are stored in the work capsule 6A and the master capsule 6B is measured in advance as a zero-point change value so as to be stored in a zero-point-change storage means 10F. A stored value is subtracted from a differential pressure value which is generated in the inspection of a work. As a result, it is possible to remove an influence due to the internal-volume difference between the side of the work capsule 6A and the side of the master capsule 6B. In addition, an update decision means 10G which updates the zero-point change value is installed, and the zero-point change value is updated at every timing decided by the means.  Thereby, even when a leak inspection apparatus is operated automatically for many hours, a high-reliability leak inspection can be executed.
