Title: Piezoelectric element scan circuit for scan tunnel microscope
Inventor: UCHIUMI HIROSHI
IPC: H01J37/28
Filed: 1988-11-22
Abstract: PURPOSE:To eliminate sudden inversion in the scan direction by generating a signal of a form to make an inversion action between a forward scan and a back scan smooth as a scan signal for driving piezoelectric elements. CONSTITUTION:The titled device is composed to generate a signal of a form to make an inversion action between a forward scan and a back scan smooth as a scan signal for driving piezoelectric elements 8-10. That is, an X-scan signal of a sine wave is generated at an X-scan circuit 2, and an X-drive element 8 is driven by this scan signal, so an inversion action from a forward scan to a back scan, or from a back scan to a forward scan, becomes smooth. A sudden inversion in the scan direction can thus be eliminated, and a sudden stress is not applied to a scan actuator, thereby production of creeps such local cracks can be prevented.

Title: Error correcting circuit and electronic equipment
Inventor: TANAKA TARO
IPC: H03M13/11
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To enable fast error correction while securing high correcting capability by omitting the decoding of external codes PO when it is decided that no error is left in internal codes PI in all rows of a block and there is no row omission. SOLUTION: The PI pointer stored in a pointer RAM is checked. If there is even one PI pointer indicating 1, a PO decoder performs PO decoding as to all the columns of an ECC block. When the PI pointers of all the rows of the ECC block are 0, the PO decoder performs PO decoding as to, for example, one column of the ECC block. When an error is detected in the PO decoding of this one column, it is considered that there is a row omission, so the PO decoder performs PO decoding as to other columns of the ECC block. When no error is detected, it is considered that there is no row omission, so PO decoding for other columns is omitted.

IPC: H04W88/18
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To maintain synchronization establishment by resetting the position in a first synchronous word detection window of a second synchronous word detection window at prescribed conditions. SOLUTION: A CPU 3 decides whether or not a calculated bit error rate matches the reset condition of a second synchronous word detection window generating part 8 stored in a memory 16. The result is written in a second synchronous word detection window generation part reset register of a synchronous register 7 as reset data. The CPU 3 calculates the bit error rate in an N frame, at any time from the number of errors of a synchronous word SW. When conditions which exceed synchronous word bit error rate X% is satisfied, reset of the second synchronous word detection window generation part 8 is performed through an AP2 generation part reset register of the synchronous part register 7.  At this time, a generation position of the second synchronous detection window AP2 is changed with a synchronous word detection pulse(d) position in a second synchronous word detection window AP 2 as a reference.
