Abstract: A recording head including at least one electrode (2, 3), and a substrate structure (1) for supporting each electrode. Each electrode and the substrate are held in contact with a recording medium or a planar intermediate member interposed between the recording medium and the recording head, so that an electric current is applied to the recording medium or the intermediate member. The substrate has a distal end portion (6) extending from a proximal portion for contact with the recording medium and the intermediate member. The distal end portion has a thickness (d) smaller than that of the proximal portion, as viewed in a direction perpendicular to a direction of extension of the end portion. The distal end portion is made of a material whose wear resistance is lower than that of the electrode.

Abstract: The invention is directed to a substantial improvement that allows to further reduce the information transmitted in the variable length encoding of numerical data blocks with encoding of single values and string lengths of consecutive values ("run length"). 
     Advantageously it is not transmitted a particular more recurrent value, when it appears as last element in a string of this parti­cular value preceded by a "run length" and followed by another "run length" or by a data block end ("data delimiter", DD). 
     When the above mentioned string of this particular value, being in the same above mentioned condition, has a unitery length, this last sole value is not transmitted; in the more general case in which N values of these consecutive values are preceded by a "run length" and followed by another "run length" or by a data block end, N-1 values are transmitted.

IPC: H04Q11/04

Abstract: This invention relates to apparatus and a method for controlling a Digital Access and Crossconnect System (DACS) from a connected toll switching system. All control messages from operations support systems (OSS) for making crossconnect changes in the DACS are first routed to the toll switch. The toll switch extracts information needed to update its database and sends a control message to the DACS. In addition, the toll switch responds to changes in traffic patterns, perhaps due to the loss of a transmission facility, to generate a crossconnect change message to the DACS to rearrange facilities for more optimum performance. 
Advantageously, the OSSs for DACS control and switch control is combined and the toll network is made more responsive to traffic pattern changes and to losses of transmission facilities.

Abstract: The operating point is stabilized at the MAX or the MIN of its optical frequency discriminating characteristic. Under the stabilized operating point, the detected difference between the average of the light intensity and a set value is fed back to a data modulator (11) so that the average value converges on a set value when a predetermined optical frequency deviation is produced. The operating point is also stabilized at the MED of said characteristic. Under the stabilized operating point, a low-frequency signal component is extracted from an electric signal output by means of synchronous detection. The operating point is stabilized at the MAX or the MIN of said characteristic. Under the stabilized operating point, a low-frequency signal component is twice in frequency by means of synchronous detection. In the fourth and fifth aspects, means such as synchronous detection is not required for the stabilization control of an operating point.
