Title: Anodised surface of an object with luminescence properties and process for producing the surface
Inventor: SCHNEEBERGER FRITZF
IPC: C25D11/18
Filed: 1989-12-14
Abstract: ABSTRACT OF THE DISCLOSURE    The market, in particular consumer goods market, has a demand for decorative surfaces on aluminum or aluminum alloy items having luminescence properties along with high-grade functional protection offered by the metal surface against harmful effects of a chemical or mechanical nature such as, for example, corrosion or wear.

Abstract: Abstract of the Disclosure:         In a mobile telephone device (10) comprising a serial interface (13b) and subjectable to an aging operation with an aging device (20) connected to the serial interface, a central processing unit (12) delivers a clock signal to an aging jig (25) through an interface unit (13) and the serial interface.  In synchronism with said clock signal, the aging jig supplies particular data to the central processing unit through the interface unit and the serial interface.          The central processing unit receives serial data supplied to the serial interface as received data in synchronism with the clock signal.  The serial data is supplied to the serial interface both during progress of the aging operation and while the mobile telephone device is not subjected to the aging operation.  The central processing unit judges whether or not the received data coincides with the particular data.  When the received data coincides with the particular data, the central processing unit carries out the aging operation.

Title: Multipoint communication system with retraining of modems
Inventor: OGAWA TOHRU
IPC: H04L1/24
Filed: 1990-07-19
Abstract: A communication system in which a plurality of multipoint connected satellite stations are connected via a down line and an up line to a master station. Each of the satellite stations monitors presence or  absence of occurrence of an abnormality in the down line, judges whether the abnormality is present or not and, where the abnormality is present, informs the master station of the nature of the abnormality via the up line.  In turn, the master station monitors presence or absence of an alarm indicating abnormality from each of the satellite stations, judges whether the alarm is detected or not and, where the alarm is detected, reads past record information concerning abnormality detection in the satellite station concerned and information on retraining execution time, then judges whether the down line is normal or not and, where the down line is normal, sends a training signal again to the down line to retrain a MODEM corresponding to the satellite station concerned. Accordingly, it is possible to quickly restore demodulation processing by each of the satellite stations to a respective normal status after a recovery of trouble in a down line.
