IPC: B65G15/60
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To provide an endless belt driving unit capable of surely preventing meandering of a belt by avoiding the movement of the belt in the direction of when it travels. SOLUTION: In a driving unit in which a pressure roller 4 and another roller are arranged so that an endless belt 2 forms a closed loop under tension, a force that works when the belt 2 tends to move in the thrust direction is restrained by forming the peripheral surface of the pressure roller 4 from a material of a low coefficient of friction, thus preventing the movement of the belt 2 and the resulting meandering of the belt 2. Also, a flange 4c regulating the movement of the belt 2 is provided, and a restraint roller 6 pressing against the edge of the belt 2 and the flange 4c is provided to avoid deformation of the belt 2.

Title: Magnetic disk substrate and manufacture thereof
Inventor: SATO MOTOHARU
IPC: H01F10/28
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To improve floating of a magnetic head by providing a magnetic disk substrate having a NiCuP film on the surface thereof, in which the NiCuP based film is crystallized and in which the crystallized film surface is polished. SOLUTION: A NiCuP film formed on the surface of a magnetic disk substrate is crystallized in advance and the surface of the NiCuP film is polished to a surface roughness Ra of not more than 100Å, before film formation of a medium. This crystallization and polishing are carried out by performing heat treatment at 350 deg.C or higher after the NiCuP plating film is formed on the substrate, and then polishing the surface thereof. Thus, by heat-treating the substrate to crystallize the NiCuP film on the surface thereof and then polishing the crystallized NiCuP film at the stage of the magnetic disk substrate before film formation of a recording medium, no further crystallization occurs in the NiCuP film and the smoothness of the surface is not deteriorated, even when the substrate is subsequently treated at a high temperature.

Filed: 1981-07-27
Abstract: PURPOSE: To accomplish a suitable cooking by enabling an input control for a magnetron by improving a cover of a container for a material to be heated and enhancing the sensitivity of the humidity sensor.  
     CONSTITUTION: In this heater, the container 16 for enclosing the material 3 to be cooked is fitted with the cover 17, and a small hole 18 for collectively discharging the steam generated from the material 3 is provided at a part of the cover 17. As a result, when the vapor pressure inside the cover 17 is elevated far beyond the ambient pressure due to the steam generated from the material 3, the steam is vigorously discharged through the small hole 18. In this case, since the container 16 and the cover 17 are rotating, the humidity detected by the humidity sensor 15 is highest when the position of the hole 18 approaches an exhaust duct 14 most closely A, and it is lowest when the position of the hole 18 is farthest B from the duct 14 since the steam is dispersed in the interior of a heating chamber 2. By such a characteristic, the difference between the humidity and the minimum value thereof can be easily detected, thereby enabling the input for the magnetron 8 to be controlled easily.
