Title: Mos type semiconductor device and its manufacture
Inventor: SAKAI ISAYOSHI
IPC: H01L29/78
Filed: 1992-11-27
Abstract: PURPOSE:To prevent the decrease of manufacturing yield, when the width of a side wall is decreased in order to improve the quality of a MOS transistor having a silicide layer in a source drain diffusion layer. CONSTITUTION:After a gate electrode 104 is formed on a P-type semiconductor substrate 101, and an N<-> diffusion layer 105 is formed, a two-layered structure wherein the inside is an oxide film 106 and the outside is a nitride film 107 is formed, and an N<+> diffusion layer 108 is formed. A titanium layer 109 is formed, and a titanium silicide layer 110 is formed by heat treatment. Since a nitride film exists on the outside part of the side wall, the film thickness of the side wall is not decreased in the elimination process of a natural oxide film using buffered hydrofluoric acid, preceeding to silicidation. Thereby the film thickness of a side wall can be reduced, while the short-circuit between the gate and the source/drain is prevented.

Title: Magnetic disk device
Inventor: SATO YOSHIHIRO
IPC: G11B5/72
Filed: 1992-12-22
Abstract: PURPOSE:To improve the corrosion resistance of a thin film magnetic recording medium by forming a Co-based magnetic film on a nonmagnetic substrate and an insulating film on the magnetic film and further forming a carbon film. CONSTITUTION:A magnetic film 3 is formed on a nonmagnetic substrate 4 and a Cr film which becomes a stable passivated coating film is sputtered in an oxygen atmosphere and formed as a Cr oxide film 1 on the magnetic film 3. A carbon film 2 is further formed on the Cr oxide film 1 by sputtering or other method to produce a thin film magnetic recording medium. The thickness of the Cr oxide film 1 is preferably <=10nm. Since the surface of the magnetic recording medium does not electrochemically connect to the magnetic film 3, a corrosive cell is not formed and an accident such as a data error is not caused. Since the corrosion of the magnetic film 3 is suppressed, the locking of data can be prevented and the reliability of the medium can be enhanced.

IPC: F16F15/30
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a smooth rotational change, by using a magnet to a fly wheel for suppressing the rotational variation of an engine, etc. SOLUTION: Though the axis center of a fly wheel 1 is coincident with a rotation shaft 2, the fly wheel 1 itself retains a slight gap 3 to the rotation shaft 2, to be arranged so as to influence a rotation by magnetic force of a magnet to the rotation shaft 2.
