Title: Rolling operation
Inventor: CHIBA ICHIROKU
IPC: B21C47/00
Filed: 1978-03-07
Abstract: PURPOSE: Metal belt is wound on a sleeve-mounted companding mandrel up to a required number of turns, then rewound on a mandrel without sleeve, thereby eliminating reel marks from the metal belt and damage from the mandrel.  
     CONSTITUTION: The leading edge of metal belt 6 is wound on the sleeve 25 of the wind-rewinder 4, then rolling is performed. When the tail edge of the metal belt left the rewinder 5, the operation is stopped, and the tail end of the metal belt 6 is inserted for winding into the grip of the sleeve 25 to start reversing the roll 2, 2 to perform rolling. When the last pass is at the odd number, the leading edge of the belt 6 is separated from the sleeve 25 of the wind-rewinder 4 at the outlet. Then the sleeve 25 is taken out from the mandrel shaft 11, and the leading edge of the belt is directly wound on the companding mandrel of the wind-rewinder 4. The product which is wound on the companding mandrel of the wind-rewinder 4 by last rolling is transferred by the coil car 9.

Filed: 1983-02-18
Abstract: PURPOSE:To prevent the ignition timing from being frequently switched even if an engine parameter is changed, by providing a hysteresis transition between the knock control area where knock control is performed and the area where the knock control is not performed. CONSTITUTION:If a knock, being generated from engine vibration or the like, is recognized, a control process enters a step 101. It is decided whether or not a knock control execution flag fKZON is already set. If the decision result is NO, the process proceeds to a step 102, and if an engine speed NE is not higher than the first decision value A, the knock control execution flag is set. While if the result in the step 101 is YES, proceeding to a step 104, it is decided whether or not the engine speed NE exceeds the second decision value C larger than the first decision value A. If the result is YES, the knock control execution flag if reset. In this way, even if an engine parameter is changed, the ignition timing is never frequently switched.
