Title: Mobile radio receiver
Inventor: YAMASHITA AKIRA
IPC: H04B1/7077
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To extend the range of synchronization tracking of a mobile radio receiver. SOLUTION: A synchronization acquisition section 11 repeats a synchronization acquisition operation even after a synchronization tracking control section 13 finishes initial acquisition to conduct re-synchronization acquisition. A synchronization position discrimination section 15 outputs a synchronization position signal 151 corresponding to a change in a reception signal 100 to a synchronization tracking section 12. The synchronization tracking section 12 uses the synchronization position signal 151 for an initial value' of a tracking phase to update the tracking phase with respect to a fluctuation in the reception signal 100.  A synchronization spread code 211 for demodulation for fluctuations in the reception signal 100 due to fading or the like, and the synchronization tracking section 12 receiving the synchronization position signal 151 (X) provides an output of a state transition denoting a tracking position signal 241 (X+1) tracking the fluctuation in the reception signal to the synchronization acquisition section 11. The synchronization acquisition section 11 compares the synchronization position obtained at re-synchronization acquisition with a tracking position signal 241 and provides an output of a new synchronization position signal 151. Thus, even temporary interruption of the demodulation operation by re-assignment of a same path is prevented.

Title: Method for testing semiconductor memory device
Inventor: NAWAKI MASARU
IPC: G11C11/401
Filed: 1989-10-03
Abstract: PURPOSE:To detect coincidence or disparateness by receiving stored data signals from memory cells on bit lines and comparing signals on bit lines which are amplified by different differential amplifiers. CONSTITUTION:When sense amplifiers (SAMP) 1 and 4 are in normal operation, bit lines B1 and B4 are high and bit lines B1# and B4# are low corresponding to data H written in memory cells MC11 and MC41 previously. Therefore, the lines B1 and B4, and B1# and B4# are equal in level and a comparator 100 decides the normal operation. Potential differences between the lines B1 and B1#, and B4 and B4# are slight before the amplification, so when malfunction is caused by the asymmetry between the layout patterns LP of the individual SAMPs, the SAMPs 1 and 4 differ in amplification tendency because they are symmetrical LPs, so that the bit lines B1 and B1#, and B4 and B4# differ in high/low potential relation after the amplification. Therefore, the lines B1 and B4, and B1# and B4# become different in level and the malfunction is decided.
