Title: Formation of bump electrode of semiconductor device
Inventor: MATSUMURA KAZUHIKO
IPC: H01L21/321
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To enable easy formation of a bump electrode only on an aluminum electrode requiring the bump electrode in a semiconductor device and also to enable suppression of deterioration of a plating solution. SOLUTION: A native oxide film 2 on a surface of an aluminum electrode 1 is removed. Thereafter, in order to prevent re-formation of a native oxide film, a semiconductor device 3 is immersed into an alkaline solution containing Ni, a laser beam 9 is emitted on the aluminum electrode 1 requiring a bump electrode to locally heat only the vicinity of the electrode and to form an Ni particle film 5. The device is washed with pure water, immersed into an electroless nickel plating solution, the laser beam 9 is emitted on the aluminum electrode 1 requiring a bump electrode, and then an Ni film 6 is formed by an electroless nickel plating process. The device is washed with pure water.  Thereafter the device is immersed into an electroless Au-plating solution, the laser beam 9 is emitted on the Al electrode 1 requiring the bump electrode, and then an Au film 7 is formed by the electroless plating process. Local heating by irradiation with the laser beam 9 enables a plating reaction to advance only on the Al electrode 1 requiring the bump electrode, whereby the bump electrode can be formed and also deterioration of the plating solution can be suppressed.

Title: Method for packing bean curd
Inventor: EBARA YASUYUKI
IPC: A23L11/00
Filed: 1984-03-22
Abstract: PURPOSE:To improve the preservability of bean curd, by keeping a formed bean curd at a relatively high temperature, putting the bean curd in a vessel, pouring sterilized water into the gap between the vessel and the bean curd, and sealing the top opening of the vessel with an air-tight seal. CONSTITUTION:The surface of the bean curd 1 coagulated, formed and cut to a proper size is cooled to about 60 deg.C. The bean curd is put into the vessel 2, sterilized cold or hot water is poured into the gap between the vessel 2 and the bean curd 1, and the top of the vessel 2 is sealed with the air-tight seal 4. The bean curd can be packaged in an almost aseptic state, since the bean curd is put into the vessel keeping a relatively hot state, and sterilized cold or hot water is filled in the vessel. Accordingly, there occurs no rapid putrefaction of bean curd with sundry germs, and the bean curd can be stored for a long period, i.e. for 2-3 weeks.

Title: Magnetic disk device
Inventor: FUJII MASATAKA
IPC: G11B21/21
Filed: 1991-03-20
Abstract: PURPOSE:To decrease the influence of floating dust existing in the device by changing the driving rotating speed of a recording medium at the time exclusive of recording and reproducing to obtain the floating space larger than the floating space at the time of recording and reproducing. CONSTITUTION:The rotating speed of the device is set at a point A at the time of executing recording and reproducing with this device. The rotating speed of the device is set at a point B simultaneously with ending of the recording and reproducing and the device is made to stand by until the next access instruction arrives. The floating quantity hB during standing by increases in comparison with the floating quantity hA at the time of recording and reproducing and the probability that the floating dust, etc., existing in the device are caught into the space between a head and a disk is decreased and the reliability of sliding is improved. The generation of the heat is further prevented by using a slider for combination use as positive pressure/negative pressure types if the generation of the heat in the device is of a problem when the rotating speed B during standing by is set higher than the rotating speed A at the time of recording and reproducing.

Title: Wire production
Inventor: MIKI SHIYOUICHI
IPC: B21B1/16
Filed: 1978-05-15
Abstract: PURPOSE: Wire material is continuously and economically provided by material treatment in heating, forming, rolling processes of wire production, effectively eliminating waste time and the difficulty of heavy wire production.  
     CONSTITUTION: For example, a 300mm diameter metal material 1 is heated to a specified temperature in heating furnace 2, extruded by extrusion-press into a 50mm diameter round bar, and subjected to 12 passes of rolling 4 to produce a 9mm diameter wire. The preceeding press-extrusion in this process eliminates the need of skin peeling, and welding-free process enables heavy-weight coil production. The existing press line is effectively utilized for continuous production without the need of new line. Thus, the production cost is reduced to about half of press- extrusion, or 70 to 80% of rolling process, providing highly economical production system.

Title: Manufacture of high tensile galvanized steel plate of excellent plating adhesiveness and good processability
Inventor: KANEKO KUNISHIGE
IPC: C21D8/02
Filed: 1978-05-15
Abstract: PURPOSE:To obtain high tensile galvanized steel plate which is excellent in plating adhesiveness, processability, and elongation and also is of small yield ratio by the procedure in which a steel containing specific amounts of C, Mn, and Cr as basic components is hot rolled at more than the A3 transformation point, washed with an acid, heated under specific conditions on a continuous galvanizing line, and then cooled. CONSTITUTION:A steel containing <=0.2% C, 0.5 to 2.5% Mn, and 0.05 to 1% Cr  as basic components is hot rolled at the A3 transformation point and then coiled at more than 650 deg.C. Then, it is washed with an acid, then heat treated, after being cold rolled as needed, at a temperature more than 700 deg.C but less than the A3 transformation point, and lastly cooled at an average cooling rate of 1 to 5 deg.C/sec until 300 deg.C. This method increases the processability and plating adhesiveness of the s teel product by adopting a high temperature coiling method after hot rolling, as well as renders it able to form a composite structure after cooling and thus renders its ductility higher due to the lumping of cementite in steel and also the concentration of C, Mn, and Cr into austenite formed after heating.
