Title: Information transmission to traveling body and position detector
Inventor: KIOGAWA TAKAO
IPC: B65G43/00
Filed: 1979-02-28
Abstract: PURPOSE: To secure economy and high reliability and also to improve maintenance efficiency by making it possible for a traveling body side to detect the position of its own by making use of a transmitted signal while transmitting information such as a command from a ground station to the traveling vehicle, etc.  
     CONSTITUTION: On a ground station side, input information Di is sent out to information-signal (frequency) setting circuit 10 by way of information transmission control and fault detection circuit CC11 and information transmission control line 12 and then led to parallel three-line induction lines 1W3 via transformer 9 and 8, and the output of signal detection circuit 7 is inputted via signal detection line 13 to CC11 which makes a decision on a fault by checking whether it agrees with D 1  or not and also decides on a fault position. On a traveling body side, a continuous- phase signal (shown by the solid-line arrow) having no relation to the intersection between induction lines 1 and 3 is outputted by cross loop coil 15 while the traveling body is running, and non-cross loop coil 16 outputs a signal with a phase difference of (π) radian in adjacent sections AWD; and both the outputs are applied to phase detection circuit 18 to detect the position of the traveling body.

Filed: 1987-02-06
Abstract: PURPOSE:To perform accurate inspection all the time, by electrically removing the total and analogous difference between a reference luminance curve and an individual luminance curve based on the gloss state of the plated part of an individual IC lead frame. CONSTITUTION:The total and analogous difference is yielded between a reference luminance curve S and an individual luminance curve P0 based on the gloss state of the plated part of an an individual IC lead frame.

In the totally agreed state, complicated irregularity signals 3 on the curve S and the curve P1 are compared. Thus the plated states are inspected. Therefore, the frame, which does not have defective plated state intrinsically but looks defective due to the gloss state of the plated part, is excluded from the object for the comparison and inspection. Thus the accurate inspection is carried out all the time.
