Granted: 1988-11-14
Abstract: The device comprises a bill discrimination section for discriminating whether an inserted bill is true or not, an escrow section capable of retaining a bill accepted by the bill discrimination section.  The stocker section includes a bill conveyor passage connecting the sections and receives a bill present in the bill conveying passage in a predetermined accumulating location by moving the bill in a direction so that the bill crosses the bill conveying passage.  The inserted bill is led to a linear passage in the stocker section through the bill discrimination section. By performing a control operation so as to either carry the bill present in this linear passage to the escrow section or move the bill in a direction in which it crosses the passage, the bill is received in either the escrew section or an accumulating location in the stocker section.

Title: Semiconductor isolation method
Inventor: LEE SANG-RAE
IPC: H01L21/76
Filed: 1990-09-10
Granted: 1993-11-08
Abstract: The  isolation  method  of   a   semiconductor   device   is characterized by (a) depositing a heat-oxidizing film (2)  on  the silicon substrate (1), (b) selectively etching the film (2) by the use of a photoresist mask, (c) etching the  exposed  part  of  the substrate to form a trench (4), (d) implanting  an  ion  into  the side wall and the bottom surface of the trench, (e)  depositing  a liquid phase oxidizing film (4) on the trench,  and  (f)  removing the mask  and  the  film  (2).  The  method  improves  a  matching characteristic of an integrated circuit (IC).
