Title: Plane moving type coordinate input device
Inventor: YONEMITSU SHINOBU
IPC: G06F3/038
Filed: 1987-12-22
Abstract: PURPOSE:To obtain good operability regardless of the size of movement quantity information by switching the functional relation between a physical movement quantity and movement information to be sent. CONSTITUTION:When a coordinates input device is moved, the physical movement quantity is detected by a longitudinal movement quantity measuring part 1 and a lateral movement quantity measuring part 2.

Title: Nonconsumable nozzle type electroslag welding method
Inventor: YAMASHITA KOZO
IPC: B23K25/00
Filed: 1993-12-22
Abstract: PURPOSE:To lessen generation length of lack of fusion generated in a welding start part by using a power source having a DC constant voltage characteristic and specifying slag depth, welding wire diameter and wet extension to specific sizes. CONSTITUTION:Welding is executed by specifying depth 11 of a slag bath to 10 to 30mm, the diameter of a welding wire 8 to <2mm and the wet extension to 0 to 2mm. A flux is melted to form the slab bath 12 by an arc from a wire 8 when welding is started. The wire 8 is as small in diameter as <2mm and the welding power source having the DC constant voltage characteristic is used and, therefore, the arc startability is extremely smooth. The part where a part at the front end of the wire 8 dives into the slag bath 12, i.e., the wet extension, is substantially eliminated and the depth 11 of the slag bath is maintained as extremely shallow as 10 to 30mm. Since the depth 11 of the slag bath corresponds to the length of the weld defect, the length of the weld defect is shorter than by the conventional methods.

Filed: 1987-12-23
Abstract: PURPOSE:To avoid the process conflicts in the title system by registering an interruption process request into a message queue and then taking said process request out of the message queue via another task in case a conflict may possibly occur between the interruption process and another process. CONSTITUTION:An interruption process 21 is started with occurrence of an interruption in an interruption process 2 and a process 22 having no possibility of interruption is carried out. A process having possibility of a conflict if exists is registered into a message queue 4 as a process request 23 and an interruption process 24 is finished. While in a normal process, a process 11 having possibility of a conflict is carried out and a due message if registered into the queue 4 is taken out for execution of a request. This operation is continued until no message is available any more. In such a way, it is possible to carry out successively those processes having possibility of mutual conflicts and to avoid the delay of the interruption processes.
