Title: Detecting apparatus of pattern
Inventor: OKA KOJI
IPC: G01B11/24
Filed: 1987-11-16
Abstract: PURPOSE:To ensure the detection of a pattern even when a low-reflectivity part exists on the surface of a conductor or the like forming the pattern, by a method wherein a spatial filter constituted by a minute light-intercepting body is disposed on a re-imaging plane of a reflected light and the detection of the pattern is conducted on the basis of the quantity of a diffused light. CONSTITUTION:A beam from a laser light source 14 is deflected through a polygon 16 to be formed into a scanning light, and this light is passed through a scanning lens 17 and applied to a printed circuit board 13 to be inspected. A reflected light is separated from the same optical path through a beam splitter 19, and it is passed through a re-imaging lens 20 to be re-imaged on a spatial filter 27. The spatial filter 27 has a minute light-intercepting body in the central part, and most of broad reflected light from a substrate element having a light- diffusing property is allowed to pass therethrough. The substrate element can be detected by detecting the passed light from the spatial filter 27 by means of a photodetecting element 22. Even when a conductor element has a part of low reflectivity due to oxidation or discoloration or the like, accordingly, this part has no effect on the detection of a conductor pattern.

Title: Infrared sensor
Inventor: AIZAWA KOICHI
IPC: G01J5/02
Filed: 1992-10-27
Abstract: PURPOSE:To facilitate detection of abnormally reduced pressure in package by providing a thermal infrared detecting part, a heating element, and a temperature difference detecting means, and reducing pressure in the package. CONSTITUTION:Constant current is fed from a power supply section 21 to a heating element 5. Heat generated from the heating element 5 raises temperature of a temperature-sensitive resistor 14 located above thus varying the resistance thereof. Variation of resistance is detected at a resistance detecting section 22 which then produces a signal proportional to the variation of resistance. This is a temperature difference signal corresponding to temperature variation caused by conduction of the heating element 5 and the temperature difference signal is generated using an output signal from an infrared detecting part 2. The temperature signal is fed to a comparator 23 which delivers an output signal to a sense output section 24 if the temperature difference signal exceeds a threshold value corresponding to an allowable extent of pressure reduction. The output section 24 notifies pressure reduction in a package below an allowable level by means of light or sound. Consequently, unoperatable/replacing time of sensor can be known.

Filed: 1990-10-26
Abstract: PURPOSE:To effective decide a malfunction by converting process data of a plant collected in a predetermined period to coordinates based on an arbitrarily set graph range, and displaying conversion data on a graph. CONSTITUTION:A plant monitoring device converts data of a plant collected by a data collector 1 in a predetermined period to a graph range arbitrarily set by a graph range converter 2 by a coordinates converter 3, and displays it on a graph display unit 4. The plant monitoring device 6 has a circuit 31 for opening a window of the graph range, and when it selects an upper end - a lower end by a selector 32, display data by a span of upper and lower ends to display it on a display unit 33, and confirms proximity to the upper or lower end by a confirming unit 34, it displays upper or lower limit malfunction on display units 35, 36. If the upper and lower limits are separated, a malfunction is predicted from the width and a trend by a predicting unit 37. If the upper limit malfunction is continued, it selects the upper limit - the lower limit of a graph range altering window by a selector 38, extracts only the upper limit malfunction to display it. Thus, the malfunction can easily be monitored by intuition.
