IPC: G11B11/10
Filed: 1990-11-29
Abstract: PURPOSE:To keep a definite distance between a magnetic field impression means and a magneto-optical disk by a method wherein a spacer is brought into contact with the magneto-optical disk, they are turned at the same speed of revolution and a holding means which holds the magnetic field impression means is always brought into sliding with the spacer.

Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for taking out a product from the mold of a molding machine in a short time required to take out the product and effectively holding the product. SOLUTION: After a resin is solidified in a cavity, the product 1 is taken out from the mold in the following sequence. First, a moving side die plate 21 is driven to retract a moving side mold 20. When the mold 20 is arrived at an intermediate position at this side of the retracting limit, ejector pins 31, 15 are forwarded synchronously with the mold 20 while subsequently retracting the mold 20. Thus, the product 1 is separated from the mold 20. Since the forwarding speed of the pin 31 is synchronized with the retracting speed of the mold 20, the product 1 is retained at the same position on the base of the machine. In this state, a conveyor 50 is moved down to the front surface of the product, and the product is received at the conveyor 50 side. Then, the pins 31, 25 are retracted, raised on the conveyor 50, and the product is recovered.
