Abstract: PROBLEM TO BE SOLVED: To obtain an extremely thin wall of roll by manufacturing a metallic hollow roll with an electrically welded tube welded a thin wall of metallic-sheet stock into a cylindrical shape. SOLUTION: A strip stock 2' being the thin wall of metallic plate stock is bent into a circular shape with plural forming rolls 4 while advancing the stock. End edges in the width direction of the stock 2' butted by bending are welded each other with a high frequency wave welding machine 5. Weld beads are removed with a bead removing device 6. The roll is cut into a prescribed dimension with a cutting device 7 to obtain the electrically welded tube 2.

The electrically welded tube 2 is drawn, further thined in wall and reduced in diameter to obtain the hollow roll. Heat transmission property and light weight property are improved because of the extreme thinness.  When the roll is used as a stationary roll, the starting time is reduced and the stand-by temp. is lowered, whereby an energy saving measures is expected.

Title: Microwave oven
Inventor: BO GUNNARU YOERUSON
IPC: F24C7/02
Filed: 1989-01-31
Abstract: PURPOSE: To enhance output control by measuring, during operating period, the switched-on time of a microwave source from the moment when an amount which varies at the start of generation of microwave power is detected. CONSTITUTION: An operating period is started when a control signal issued by a controller 5 closes a power switch 3. This occurs when the time is elapsed to a moment t1 in the diagram. A relatively small current flows through a current sensor 4 up to a time point t2 at which time a magnetron 1 starts, significantly increasing the current, which becomes stable at a high level thereafter. The effect of this change on average power during the operating period is eliminated by measuring the switched-on time of the magnetron 1 not from the point t1 but from the starting point t2 of the magnetron 1 which was sensed during each operating period. Then the switch 3 is turned off according to the time measured from the point t2 .
