Title: Method for detecting bending of lead wire in flat-pack type ic
Inventor: ASAI KOUICHI
IPC: G01N21/956
Filed: 1985-09-27
Abstract: PURPOSE:To enable a bending state of lead wires to be easily judged, by emitting light from a flat-pack type IC side to a semitransparent plate side and comparing information, which is obtained by picking up shadows of the lead wires generated on the semitransparent plate from its back, with reference information, which corresponds to a normal flat-pack type IC with no bending state of lead wires. CONSTITUTION:IC 28 is positioned at an prescribed position of a semitransparent plate 16 by a holding head 30 and is pressured with force prescribed in advance, and then light is emitted from a lighting fixture 18. Because only free terminal parts of the lead conductors 82 make a close contact with the semitransparent plate 16 by pressure, the shadows are divided into unclear shadows and dense and clear ones. The shades of the IC 28 generated on the semitransparent plate 16 are picked up by a TV camera 22. When the output signals of this TV camera 22 are binary-coded so that the signals corresponding to densely shaded parts are made O and those corresponding to thinly shaded and shadowless parts are made 1, a series of binary-coded signals, in which images of the free terminal parts in the lead conductors 82 of IC 28 are shown, can be obtained. Information related with the inspection object IC 28, obtained in this way, is compared with reference information which is supplied from a reference information set-up device 70 through a bending-judged device 68.

Title: Filter switching method
Inventor: TASHIRO NAOTO
IPC: B01D46/44
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To prevent the effect of the fluctuation of exhaust pressure upon film forming at the time of filter switching by closing a valve of a branched pipe in the course of discharging and opening a valve of another one branched pipe when detecting that the pressure of the back side of a filter incorporated in the exhaust branched pipe exceeds a limit and when film forming in a film forming device is stopped. SOLUTION: When the film forming in a normal pressure CVD device is finished, a switchable signal 14 is given to a switching valve driving device 13 from an exhaust gas discharging device 1. When the filter 2 is clogged with film forming to reach a switching set value, a signal of a life A in a display circuit 12 is transferred to the switching valve driving device 13, but the switchable signal 147 is not transferred during the film forming. When the film forming in the normal pressure CVD device is stopped, a switching executing signal 15 is transferred to the exhaust gas discharging device 1 by the switchable signal 14, and then, a switch valve 4 is closed and a switch valve 5 is opened to switch a discharge line to a filter 3 side.  When the fluctuation of the exhaust pressure is eliminated, a next material to be film-formed is transported to the normal pressure CVD device to start the film forming.
