Title: Vertical mill and its gap adjusting method
Inventor: MIZUNO YOSHIYUKI
IPC: B02C15/04
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To make the minimum gap between a crushing table 2 and a roller 3 adjustable without stopping a mill. SOLUTION: An object to be milled is milled between a crushing table 2 and a roller 3 and downward swing of the roller 3 is carried out by a hydraulic cylinder 7 and the minimum gap between the crushing table 2 and the roller 3 is regulated by a stopper 20. The stopper is energized by a spring 24 and constantly brought into contact with a projecting piece 12 interlockingly with the swing of the roller 3. Even if the roller 3 downwardly swings owing to that the layer thickness of the object is abruptly thinned, following that, the stopper moves and owing to the buffering function of the spring 24, no noise and no vibration are generated. Adjustment of the minimum gap is carried out by adjusting the downwardly swinging position of the roller 3 by the hydraulic cylinder 7.  If there exists an object to be milled between the crushing table 2 and the roller 3, it becomes hard to carry out the adjustment and, therefore, only the supply of a raw material is stopped. In any case, the minimum gap can be adjusted without stopping the operation of a vertical mill.

Title: Erasing method for recording information of optical disk
Inventor: KAWAKAMI HARUO
IPC: G11B7/30
Filed: 1987-01-09
Abstract: PURPOSE:To prolong the storage life of recording information on an optical disk and to erase the information by using a comparatively low output by providing a preheat means in addition to an erasure laser. CONSTITUTION:A laser beam 20 from an erasure semiconductor laser 11 is collected as a spot 22 onto an optical disk 21 via an objective lens 15. On the other hand, the laser beam 24 from the semiconductor laser 16 for preheating is collected as a spot 25 on the disk 21 via the objective lens 15. The relation of position of both the spots 22, 25 is decided so that the spot 25 is subjected to preheating just before the laser beam 20 reaches the spot 22. Thus, the vicinity of the erasure spot 22 is subjected to preheating. Then even with a medium material having a small crystallizing speed used, since the position to be erased is subjected to temperature rise already, the erasure is applied in a short period even with a semiconductor laser having a comparatively low output and the storage life of the recorded information is extended.
