Title: Magnetic resonance imaging device
Inventor: YONEDA SUKEHITO
IPC: G01R33/385
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of residual magnetization generated at a magnetic pole piece upon an image by arranging a ferromagnetic substance on the void side of a means for generating a gradient magnetic field. SOLUTION: A ferromagnetic substance 7 such as soft iron is arranged on the void side of a gradient magnetic field coil 1. When the gradient magnetic field is impressed, the residual magnetization opposite to the residual magnetization generated at a magnetic pole piece 2 is generated since the ferromagnetic substance 7 is positioned, facing the magnetic pole element 2 with the gradient magnetic field coil 1 in-between. Then, the residual magnetization generated at the ferromagnetic substance 7, which is provided on the void side of the gradient magnetic field coil 1, and made opposite to that of the magnetic pole piece 2 is used for canceling the residual magnetization of the magnetic pole piece.  Since the magnetic pole piece 2 is apart when it is observed from a uniform magnetic field space but the ferromagnetic substance 7 provided on the void side of the gradient magnetic field coil 1 is near rather than it, the residual magnetization generated at the ferromagnetic substance 7 provided on the void side of the gradient magnetic field coil 1 is smaller than the residual magnetization generated at the magnetic pole piece 2 so that the residual magnetization can be canceled.

Title: Vapor cleaning method and its device
Inventor: KUROKAWA HIDEAKI
IPC: B08B3/08
Filed: 1990-09-13
Abstract: PURPOSE:To generate a large quantity of condensate so as to elevate the cleaning effect by the condensate by cooling the object to be cleaned during the cleaning in vapor. CONSTITUTION:The mixed vapor, which contains 3-20% isopropyl alcohol and is blown against the surface of a substrate 102, condensates by being cooled the substrate 102. Since the IPA in the mixed vapor has the OH group being the hydrophilic group, the condensate in the mixed vapor, even with the substrate having hydrophobic property similar such as a semiconductor wafer, adheres to the surface, and it follows that the condensate washes away the impurities on the surface of the substrate. In this example, since the substrate 102 is cooled directly with a cooling medium, the quantity of the condensate condensing on the surface of the substrate increases, and favorable cleaning becomes possible. Then, switching valves 112 and 113 are changed over to clean the rear side of the substrate in mixed similarly. At this time, the substrate 102 is cooled by bringing the cooling medium into direct contact with the surface side of the substrate. Lastly, by letting overheated vapor, or the like 115 flow to both rooms, both sides of the substrate are dried.
