IPC: H02M3/156
Filed: 1986-01-20
Abstract: An apparatus for generating a constant dc output voltage from a dc input voltage having a varying magnitude comprising an inductor for storing an electrical charge and a semiconductor switch for controlling the application of the input voltage to the inductor. The apparatus further comprises an error amplifier which compares the output voltage to a reference voltage and generates an error signal voltage proportional to the difference between the two voltages. An analog voltage divider generates a control voltage proportional to the ratio of the error signal voltage to the input voltage. The control voltage is applied to a pulse width converter which controls the duty cycle of the semiconductor switch responsive to changes in the input voltage such that the output voltage remains constant.

Abstract: The cap is mounted so as to be swivellable about an axis extending approximately parallel to the direction of travel of the tank wagon. There is at least one closure arm provided which is mounted so as to be swivellable, secures the cap in its closed position and is likewise swivellable about an axis extending approximately parallel to the direction of travel. In this case, at least one first cam part is provided which during a relative movement in relation to the tank wagon swivels the closure arm counter to the effect of a spring element applied to it into a position, in which it is out of engagement with the cap. The latter is raised slightly by a spring element applied to it in the opening direction so that, during the further travelling movement of the tank wagon, a second cam part grips below the cap and swivels it upwards into its open position. Further cam elements may also be provided which bring the cap back into its closed position so that the closure arm can again assume a position, in which a radial projection mounted on it grips over the top of the cap and secures it in its closed position. <IMAGE>

Abstract: In a virtual memory data processing system, the use of a pageable External Page Table data structure for recording current status and disk address information for each virtual page in the system and a non-pageable or pinned table of tables, provides improved system performance when a large number of virtual pages are to be operated on in the same manner. As disclosed, each page of External Page Table entries can record a predetermined number of entries (512), depending on the byte capacity of each virtual page (2,048) and the size of each entry (4 bytes). One page of 512 entries corresponds to 1 megabyte of virtual storage (512 × 2,048) and also appears as one entry in a pinned External Page Table. The pinned External Page Table is referred to as the "XPT of the XPT," and has the same format as the pageable XPT. A 256 megabyte segment of virtual memory is representable in the XPT of the XPT by 256, 4 byte entries, or one-half of a page. 
     Where all virtual pages represented by a page of XPT entries are to be processed in the same way (i.e., created, destroyed), one operation on one entry in the XPT of the XPT is made, rather than 512 operations on the 512 entries of the XPT.

Abstract: An improvement is disclosed to the conventional single node operating system to provide a distributed file manage­ment system (DFS) with a plurality of nodes (A,B) and a plurality of files (5). The DFS uses the UNIX operating system tree structure employing inodes (data structure containing administrative information for each file (151,152) to manage the local files and surrogate inodes (s_inode) to manage access to files existing on another node. In addition, the DFS uses a lock table to manage the lock status of files. The method which implements the DFS locking of records and files involves the following steps. If the file is a local file, then the UNIX operating system standard file is used. However, if a remote file is to be locked, the UNIX operating system LOCLF and FCNTL system calls are intercepted and a remote process call (RPC) DFS_LOCK_CONTROL is executed. The server node (A) receives the remote process call and carries out the lock request. The request could entail locking a single record, a set records or the whole file. The server then acknowledges receipt of the RPC by sending a signal while the client surrogate inode is waiting for a reply from the DFS_LOCK_CONTROL RPC. The client confirms the reception of the lock and sends an acknowledgement to the remote server. The server updates the lock table after receiving the ackowledgement, then DFS_LOCK_CONTROL'S acknowledgement, then DFS_LOCK_CONTROL updates the lock table.

Abstract: A relational database is created and queried through the use of an outliner-style text editor which permits automatic generation of data entry forms for the creation of records. Data entry and editing are simplified and errors are minimized because changes in the outline are automatically reflected in the data entry forms and thus the automatically updated records. Data retrieval is driven through the manipulation of the outline to allow simple and complex queries without utilizing a database programming language. A specialized global field is utilized in which identical field names may be repetitively inserted into several databases. In the data entry mode, a global value can be set and that value is automatically inserted into each database record containing that global field as they are created so that relations are made automatically within the various databases. In the data retrieval mode, the global field can be used to control the display of the outline to truncate the outline to only those categories and fields containing data for a specific global field value, thereby to display only relevant outline portions. A field mapper allows the operator to immediately see the changes in the outline and direct old fields to new names or positions and indicate new fields which are to be inserted into the existing records, all prior to execution of the changed outline in terms of data entry. The query mode features a continually displayed outline in an Outline Window. Criteria are specified in a Criteria Window in which one or more fields are assigned specific search values. Records matching the criteria are displayed in a Response Window. For an outline-wide word occurrence search, areas of the outline which include an occurrence of the word are highlighted. I
