IPC: G11B19/247
Filed: 1994-11-18
Abstract: PURPOSE: To quicken the restorative operation to a reproducing operation state when out-of-focus occurs by free-run running a spindle motor and performing focus control operation in a free-run running state. CONSTITUTION: A disk player is constituted so as to make the state that no rotational drive operation of the spindle motor 2 by a motor control circuit 11 is performed when the out-of-focus occurs, and make the state that the spindle motor 2 is rotated freely, that is, the running state called as the free-run. In such a case, since the focus control operation is performed in the free-run running state, and the rotational control operation of the spindle motor is performed when focus is set, the restorative operation to the reproducing operation state is performed rapidly compared with the method restoring the spindle motor to the reproducing operation state after stopping it temporarily when the out-of-focus occurs.

Title: Method for multi-layer weld with using laser sensor
Inventor: TERAWAKI BUNICHI
IPC: B23K9/127
Filed: 1994-10-28
Abstract: PURPOSE: To provide the welding method capable of precisely and easily executing multi-layer weld. CONSTITUTION: A weld pass of a first layer is taught. Weld passes after a second pass are set by a shift quantity for the taught pass of first layer. In welding the first layer, the deviation between taught pass and actual one resulting from the insufficient precision of positioning and assembling of a work is detected at every prescribed cycle so as to store a correcting quantity. In welding the second layer and thereafter, the shift quantity for each layer and correcting quantity for each point are added so as to obtain weld pass for each layer and welding is executed. Because welding is executed while position deviation is corrected after the second layer, precise multi-later weld is executed. Further because weld pass is not required to be taught but shift quantity only is set after the second layer, thus, multi-layer weld is easily executed.
