Title: Apparatus and method for three-state database for automatic optical inspection system
Inventor: SUKOTSUTO FUIRITSUPU SUNIITOKA
IPC: G06T7/00
Filed: 1991-04-10
Abstract: PURPOSE: To detect a flaw by forming a database having black, white and gray parts corresponding to a region where the characteristic point of a printing circuit board(PCB) must appear, a region where must not appear and a region where may appear or not. CONSTITUTION: A database of a signal showing the image of the characteristic point of a PCB is formed. This image is composed of a pixel row and has either one of the first state (black) and second state (white) arranged on a series of scanning lines by the block state pixel corresponding to the characteristic point of the PCB. A first means receives the signals corresponding to present and previous scanning lines and a second means discriminates a run boundary and a third means judges a run state. A fourth means judges a run state before coincidence and a fifth means changes a common difference number state of the preliminarily selected pixel in the vicinity of the boundary to a third state (gray).

Title: Feed water solenoid valve
Inventor: SAKAI YUTAKA
IPC: F16K31/06
Filed: 1979-06-20
Abstract: PURPOSE: To provide a feed water solenoid valve which can be operated correctly in a wide water-pressure range, by forming a common water inlet chamber and a common water outlet chamber in the valve body of a pilot operated feed water solenoid valve and a direct operated feed water solenoid valve.  
     CONSTITUTION: In case that a direct operated feed water solenoid valve is designed such that its maximum operating water pressure is, for instance, 0.4kg/cm 2  and a water pressure lower than that is acted, plungers 7 of the direct operated solenoid valve and a pilot operated feed water solenoid valve are moved upward against the force of coil spring 14 when electromagnetic coils 15 of these two valves are excited. Here, diaphragm 5 of the pilot operated solenoid valve is not detached from its valve seat 4 because of low water pressure, but valve body 5' of the direct operated solenoid valve is moved upward from valve seat 4 together with its plunger 7, so that water inlet chamber 2 and water outlet chamber 3 are communicated with each other. On the other hand, in case that a water pressure higher than 1kg/cm 2  is applied, the pilot operated solenoid valve is opened but the direct operated solenoid valve is not opened since its pluner 7 can not raise valve body 5' because of high water pressure.
