Title: Magnetic disk device
Inventor: NAKAYAMA MASAAKI
IPC: G11B21/21
Filed: 1990-03-30
Abstract: PURPOSE:To prevent the flawing of a medium due to the contacting between a magnetic head and a magnetic disk plate and to a head crush caused by another magnetic head owing to the generation of a large amount of dust by floating the magnetic head above the prescribed height when the head crush generates.

Title: Chain type slit cutting machine
Inventor: IKEDA KAZUYUKI
IPC: B27B17/00
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To allow cuttings from being scarcely clogged by forming an interval between a forward passage and a reverse passage from a front end of a guide bard to a base end, thereby suppressing a cutting resistance to a small value in the case of cutting a bag-like slit at a timber. SOLUTION: A chain saw 2 is urged, for example, to a butt end of a post 34 by a front end of a guide bar 3. Thus, only a front end of a slit cutting machine 1 handles cutting it in a depth direction to form a closed bag-like slit 35 from a butt end of the post 34 in a lengthwise direction. At this time, since an interval between the saw 2 of a forward side directed from a base end toward the front end and the saw 2 of a return passage side directed from the front end toward the base end is wide at the front end side and narrow at the base end side, a gap between a sidewall of the slit and the saw 2 becomes wider, the nearer it is disposed at an inlet side of the slit 35 as the slit cutting is proceeded.  Therefore, the saw 2 is scarcely interfered with the already cut slit frame, excess cutting or increase in driving resistance is eliminated, and hence cutting chips are easily discharged.
