Abstract: An improvement support system including an input unit, a display, an arithmetic processing unit and a storage unit, the storage unit stores analytical data containing analytical information corresponding to “phenomenon” or “influence” and “cause” or “measures” for each of failure modes, and malfunction generation historical data in which malfunction information formed based on the contents of malfunction and related to the failure mode of the analytical information is sequentially accumulated every time the malfunction is detected after the system is started. The arithmetic processing unit has a function of retrieving the analytical data using the malfunction information as a key and detecting the failure mode correlated with the malfunction. Thus, the number of malfunctions related to the analytical information regarding each failure mode is counted and the total number of malfunctions related to the failure mode is displayed with the contents of the failure mode in the display.

Abstract: To provide a three-dimensional monitoring apparatus capable of detecting with high accuracy an incoming of an object into a predetermined three-dimensional space by using pattern light as a detecting carrier. A three-dimensional monitoring apparatus comprising (1) an irradiating device for irradiating predetermined pattern light to three-dimensional space S to be monitored, (2) an imaging device for imaging a projection pattern projected by irradiating of the pattern light on an incoming object M and on a screen 5 in the space S to capture image data and (3) a measuring device to measure a position of the object M based on the comparison between a monitoring image captured by the imaging device when there is the object M in the space S and a reference image captured by the imaging device when there is no object M in the space S.

Abstract: A detection unit 1 for detecting an electric field or a magnetic field is placed above a circuit board 4 to be detected. A control device 3 allows the detection unit 4 to carry out detection processes while moving the detection unit 1 in a predetermined direction with an electric current being applied to the circuit board 4 so that an electric field distribution or a magnetic field distribution on the circuit board 4 is detected. Moreover, the control device 3 compares the results of the detection with reference data that has been preliminarily registered, and if there is any portion between the two pieces of data that is not coincident with each other, it is determined that the corresponding circuit board 4 is a defective circuit board. Thus, it is possible to detect any defective portion on the printed circuit board with high precision in a non-contact state to the circuit board.

Abstract: In a light curtain generating device comprising a pair of pillar assemblies for supporting arrays of light emitting and receiving units which are placed opposite to each other so as to form a light curtain for detecting an object between the pillar assemblies, the light emitting and receiving unit arrays each consist of a group of single-beam optical modules so that the length of the arrays of light emitting and receiving units and the pitches of the individual light emitting and receiving units can be selected at will. Therefore, the light curtain generating device can readily adapt itself to each particular application at low cost and in a highly precise manner.
