Title: Method and apparatus for preventing pin fraud on coin telephones that use battery reversal pulses to meter charges
Inventor: AKHTERUZZAMAN
IPC: H04M17/02
Filed: 1996-09-03
Granted: 2000-02-01
Abstract: Pin fraud of battery reversal pulse metered sophisticated coin telephones is detected and prevented by the method and apparatus of the invention.

The column scrolling method is faster than scrolling by rows when the number of rows in the window is small and/or the number of rows to scroll is high. Program instructions for implementing the scrolling are preferably stored in a basic input-output system (BIOS) read-only memory (ROM) chip to provide a built-in, backward compatible low resolution display capability, e.g. a color graphics adapter (CGA) text display, for a newer computer or other data processing device.

Title: Method of inspecting the mask pattern by use of vernier with separate exposure alignment
Inventor: CHEN JIA-SHIANG
IPC: G03F9/00
Filed: 1998-10-27
Granted: 2000-05-21
Abstract: The invention relates a method of inspecting the mask pattern that uses vernier and separate exposure alignment. The mask pattern is first divided into two parts, which are left part, right part or front part, rear part, to do the exposure. On the first part of the mask pattern, the first vernier scale is formed on the first side of the first edge and the first overlapped area is formed on the second edge. The relative position of the second edge to the first part of mask pattern is the same as that of the first side to the first edge, but is opposite to that of the first part of mask pattern to the whole mask pattern. On the second part of mask pattern, the second vernier scale is formed on the second side of the first edge stated above. The second overlapped area is formed on the third edge. The relative position of the third edge to the second part of mask pattern is the same as that of the second side to the first edge, but is opposite to that of the second part of mask pattern to the whole mask pattern. The first part of mask pattern stated above is then used to do the first exposure on a wafer. By using the second mask pattern stated above and making the second overlapped area overlap with the first overlapped area on the first part of mask pattern, the second exposure is then proceeded on the wafer stated above. Finally, the alignment accuracy of pattern exposure is determined by comparing the first and the second vernier scale position on the double exposure wafer.
