Title: Polishing method using magnetic fluid
Inventor: KATO YASUSHI
IPC: B24B37/00
Filed: 1987-02-09
Abstract: PURPOSE:To improve the extent of efficiency, by dipping a float in a magnetic fluid containing abrasive grains, giving buoyance to this float in making an external magnetic field act on the magnetic fluid, while pressing these abrasive grains between a float acting surface and a workpiece to this workpiece by dint of the buoyancy, and giving relative motion to an interval between the workpiece and the magnetic fluid. CONSTITUTION:A workpiece 3 is attached to the underside of a disc 6 as a driving jig free of rotation, and it is dipped in the vicinity of a level of a magnetic fluid 2 containing abrasive grains in a vessel 1. Here, a float 5 is dipped in the magnetic fluid 2, and if an external magnetic field is made to act on by a magnet 4 from the lower part of the magnetic fluid 2, buoyancy acts on these abrasive grains, floating them upward, and thereby an abrasive grain layer of high density is formed in the upper part of the magnetic fluid 2. Simultaneously with this, the buoyancy is given to the float 5 as well, and the float 5 is floated upward, strongly pressing these abrasive grains existing in the upper part to a surface of the workpiece 3. Under this state, when the driving disc 6 is rotated with a vertical shaft 61 as the center, the under side being contacted with these abrasive grains is polished. In this case, the polishing rate is improved by action of the float 5.

Title: Resin-sealing device for semiconductor element
Inventor: TANAKA MINORU
IPC: B29L31/34
Filed: 1985-02-13
Abstract: PURPOSE:To enable to perform a resin sealing with very good precision by a method wherein the matching surfaces of the top force and the bottom force are formed curvedly in a protruded form to the side to push in advance in such a way that the matching surfaces become flat in a state that the top force and the bottom force are being clamped. CONSTITUTION:The surfaces of a top force 14 and a bottom force 15 are formed curvedly to the lower direction, that is, curvedly in a protruded form to the side to push in such a way that the matching surfaces of the top and bottom forces 14 and 15 become flat in a state that the top and bottom forces 14 and 15 are being clamped. That is, the surfaces are formed in such a way as to be made to bend as much as the amount to bend at the time of the clamping in the reverse direction in advance. The amount to be made to bend in advance is found out from the pressing force, the stiffness of each structure such as the platens and the stiffness of the top and bottom forces. By such a constitution, the matching surfaces of the top and bottom forces, whereon a resin sealing is performed, become flat even when the clamping is performed and the moving platen 13 and upper platens 10 bend, and if a resin sealing is performed in this state, a dimensional error and so forth due to strain is never generated like the case in conventional methods and a resin sealing of very good precision can be performed.

Title: Method for controlling fan of drying device and device for drying photosensitive material
Inventor: YAMAMOTO TAKERO
IPC: G03D15/02
Filed: 1993-02-16
Abstract: PURPOSE:To prevent drying unevenness at the initial time of starting a device. CONSTITUTION:With the power source switch on, both a drying fan and a heater are on by the step 150 and a drying air is supplied to a drying chamber to rise the temp. of the drying chamber to the temp. capable of processing a film and when the step 152 judges that the film processing starts, the drying air is continuously supplied to the drying chamber (step 154). Next, the step 156 judges that the tip part of the film reaches the drying chamber, the intermittent operation of the drying fan starts. On-off of drying fan at the time of the intermittent operation is executed for a short time so that the drying fan does not reach the rated operation and the film at the initial time of starting the processing is dried by using smaller quantity of drying air than that of the rated operation. As a result, the film at the initial time of starting the processing is prevented from becoming over drying state caused by receiving the heat from a transfer roller or a guide and the noise from the drying fan at the intermittent operation is also suppressed.
