Title: Pressure casting method
Inventor: ISOBE TOSHIO
IPC: B22D18/02
Filed: 1980-02-12
Abstract: PURPOSE: To prevent the abrasion of a sprue part of delivering molten metal into cavity and perform pressure casting smoothly by narrowing said sprue part, flowing a coolant therethrough, and pressing the molten metal in the cavity after confirming the closing of the sprue part by solidification.  
     CONSTITUTION: Molten metal is injected by a gaseous pressure from a melting tank 10 into the cavity 13 formed by a cope 4 and a middle die member 3. When the gaseous pressure reaches the set pressure of a regulator 17, a coolant is injected from a valve 24 into a cross gate part 9, whereby cooling is started. First, the molten metal solidifies from the lower part of a sprue 19 assuming a conical shape, thereby closing the sprue 19. The completion of the solidification is detected from the temp. measured with the thermocouple 30 disposed in the middle die member 3. Thence, pressure is exerted by a pressing punch 6. After the completion of the solidification, the pressing force of the cylinder 8 is released and the cope 4 is pulled up by the operation of the main cylinder 7. The product is bound to the cope 4 and is removed from the middle die member 3. Again the pressing punch 6 is pushed out to extract the product.

Title: Incoming call transfer system for packet exchange network
Inventor: SHIMADA TSUGUHIRO
IPC: H04L45/24
Filed: 1993-02-02
Abstract: PURPOSE:To attain the operation of a backup line with flexibility and high extension performance by dynamically storing information making the backup line correspondent to a subscriber line. CONSTITUTION:A terminal equipment PT1 detecting a fault in a subscriber line L1 accesses link connection to use a backup line L5. A packet exchange node PS1 detects it. The node PS1 detects an address of the terminal equipment PT1 and rewrites a destination DTE address into that for the line L5 to send an incoming call request when a line management table relating to the subscriber line L1 indicates disable use of the terminal equipment PT and a DTE address of the line L5 is registered in a backup line address. The node PS1 receiving the request detects the rewritten address and transfers the incoming call to the terminal equipment PT1 through the line L5 when the content of the line management table relating to the line L5 indicates the availability of the line L5. Thus, the line L5 is used when a fault takes place in the subscriber line.
