Abstract: A computer network comprises first and second computers, each having a recovery facility for recovering a two-phase commit procedure and a recovery log. The log comprises a log name log which stores the names of other logs involved in a commit scope and a sync point log which stores sync point phase information. The log names are exchanged prior to a request for sync point. If a failure occurs during sync point, each recovery facility in the commit scope again exchanges log names to verify that there was not a log failure since the prior exchange. Absent a log failure, the logs are used to recover from the sync point failure. Communication facilities are interposed between the first and second computers and include log name exchange tables which record the previous exchanges of log names between the first and second computers. If a protected conversation is initialized from the first computer to the second computer and log names were not previously exchanged, then the communication facilities intercept the conversation and hold it until log names are exchanged.

Abstract: According to this invention, a waveform data input section (100) inputs sequential discrete waveform data to be observed. A level restricting section (3, 7) determines whether a level of the other data in a predetermined data period including a predetermined number of data continuous to one data of the discrete waveform input data is existed or not within a predeter mined restriction value using a level of the one data as a reference level, directly outputs the data when the level of the data is existed within the predetermined restriction value, and restricts the level of the data within the predetermined restriction value to output the data when the level of the data is not existed within the predetermined restriction value. A averaging section (8) averages the predetermined number of data output by the level restricting section (3, 7). A control section (104) sequentially shifts a sequence of the one data having the reference level in a determining operation of the level restricting section (3, 7), thereby causing to output smoothed data for the waveform data to be observed from an averaging section (8). A display section (102) displays, under the control of the control section (104), the smooth data output from the averaging section (8).

Abstract: An insulated lead frame is disclosed. The preferred embodiment contains a lead over chip lead frame (25) having an aluminum oxide insulator (30) on portions of the power supply busses (28) where no electrical connections will be made. The aluminum oxide (30) may be easily deposited by an arc deposition process such as by plasma deposition. A mask prohibits the aluminum oxide from coating the places on the power supply busses where electrical connection, such as by wire bond, will be made. Wire bonds crossing over the power supply busses (28) as they connect bond pads (23) to the lead fingers (27) of the lead frame (25) are therefore less likely to short to the insulated power supply busses (28). A semiconductor packaged device having an aluminum oxide coating to the underside of the chip support pad is also disclosed. The aluminum oxide coating promotes adhesion between the chip support pad and the encapsulant, that is typically plastic, thereby preventing the chance of delamination and package cracking.

Abstract: The invention relates to a plug socket element (11) having a retaining body (12) and a number of contacts (13) which are located side-by-side, into which plug socket element (11) both a plug (20), which corresponds in shape and number to the contacts, and a narrow plug (21), with a smaller number of contacts and a smaller dimension in the row direction of the contacts (13), can be inserted. In order to prevent lateral play between the narrow plug (21) and the inner walls of the plug socket element (11), spring guide means (14; 14') are integrally formed on the retaining body (12) and/or the contact insert (18) on both sides of the push-in part of the narrow plug (21). These guide means (14; 14') are constructed from elastic material in such a manner that they form a lateral guide for relatively narrow plugs (21) but in contrast are pressed down, for example via a lifting incline (15), during the insertion of broad plugs (20). The guide means (14; 14') according to the invention thus ensure reliable contact-making between narrow plugs and broad socket elements in the event of movement of the plug in the inserted state. <IMAGE>

Abstract: An incinerator system includes a main chamber (32), double reburn tunnels (41, 42), an excitor (134) within a reburn tunnel, a grate (234) near the incinerator's inlet (231) to permit the drying and initial combustion of refuse, and an ash scoop (278). The grate (234) placed at the main combustion chamber's entrance and above the incinerator's floor (33) permits the retention of newly introduced refuse for a brief period of time. During this time, the refuse may dry, loose its volatile hydrocarbons, and then drop through to the main chamber's floor and undergo its usual combustion. For very high Btu waste, the grate permits the initial, very hot burning to occur away from the incinerator floor to prevent slagging. A fluid may pass through the grate to keep it from overheating. In particular, air may enter the main incinerator chamber through nozzles (355) placed on the grate to both cool the grate and support combustion.
