Title: Synchronization establishment system
Inventor: FUJINO SHOJI
IPC: H04Q11/04
Filed: 1992-01-29
Abstract: PURPOSE:To reduce the existence of a switching transition process for the number of protection stages necessary for synchronization pulling-in and synchronization protection within negligible range in the case of having an individual synchronization pattern between modules and switching the module concerning a synchronization establishment system. CONSTITUTION:The synchronization establishment of a module 1 of a master side is notified from the module 1 of the master side to a module 2 of a slave side. In the module 2 side of the slave side, the synchronization operation of its own module is shifted into a waiting mode with the synchronization establishment notification from the module 1 of the master side and even the abnormality of the synchronization pattern over the number of the protection stages is detected, it is not judged to be step out and a pulled-in phase is held. When the module 2 receives a notification that the module 1 of the master side generates step out from the module 1 of the master side and then detects the normality of the synchronization pattern of the several stages immediately before, the processing operation of the module 2 on the side on the slave is restarted by judging the module 2 to be synchronized.

Title: Inspection of surface treatment of printed wiring board
Inventor: SONODA YOSHIAKI
IPC: H05K3/00
Filed: 1985-01-29
Abstract: PURPOSE:To speed up the inspection of the treatment of a printed wiring board by irradiating light to the surface of the printed wiring board which is subjected to a surface-roughening treatment, measuring the angle at which the reflected light changes sharply, comparing the angle with the above-mentioned angle of a standard sample and discriminating the surface condition. CONSTITUTION:A light source 4 is disposed right above the surface 3 of the circuit pattern of the printed wiring board subjected to the surface-roughening treatment. The light is irradiated from the light source 4 to the surface 3 of the circuit pattern of the printed wiring board 1 and the quantity of the reflected light, i.e., the degree of the brightness on the surface is observed by a scope 5 while the angle with the surface 3 of the circuit pattern is changed. The point where the brightness changes considerably is found and the angle alpha of the scope in this stage is read by an angle reader 6. On the other hand, the angle alpha is measured with the standard sample of the known surface treatment depth by the similar method and the relation between the surface treatment depth and the reflection angle is preliminarily determined. The surface treatment depth corresponding to the above-mentioned angle alpha is read from a graph and the defectiveness and non-defectiveness of the sample are discriminated. The inspection of the treatment of the printed wiring board is thus speeded up.
