Title: Conductive ball mounting method
Inventor: SAKAI TADAHIKO
IPC: B23P19/00
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To carry and mount conductive balls on a work by vacuum-sucking and picking up all of them with suction holes of a mounting head. SOLUTION: A mounting head 22 is positioned above a vessel 2 of a solder ball feeder and actuated to move up and down in a first stage to vacuum suck and pick up solder balls 1 with many suction holes 25 formed into the lower face of the head 22. The head 22 fails in the ball pick up in this first operation to result in some suction holes 25 empty of the ball 1, and is again actuated to move up and down in a second pickup motion. Thus, the pickup motions are repeated several times to vacuum-suck and pick up the balls 1 to fill all the holes 25 and carry them to a work.

IPC: C12P7/64
Filed: 1985-02-16
Abstract: PURPOSE:Fat and oil is hydrolyzed using an aqueous lipase solution which previously contains glycerol to enable continuous hydrolysis of fat and oil in a practical scale without deterioration of the lipase solution. CONSTITUTION:In the hydrolysis tank 1, an oil melting lower than 40 deg.C such as olive oil, from tank 2 and an aqueous lipase solution of more than 50 units/ ml, containing previously at least 15wt% of glycerol, from tank 3 are brought into contact through a porous membrane 4 by allowing them to flow in the reverse directions at 10-40 deg.C. The fatty acid formed is recovered in tank 5 and the glycerol formed in the lipase solution is recovered through filter 6 and glycerol concentrator 7 into tank 8. Thus, while glycerol is recovered, more than half of the lipase solution is recycled and water is fed from tank 9 to adjust the amount of glycerol in the lipase solution so that it becomes totally lower than 25wt% for hydrolysis.

Abstract: PURPOSE:To prevent the cutting of a wiring due to steps by a method wherein oxygen ions or nitrogen ions are implanted to form insulating regions in a thin film and a FET operating region is separated individually in a state that there is no step. CONSTITUTION:A poly silicon thin film 11 is formed on an insulative substrate 10 and a mask 12 is formed to a region to become a FET operating region in the film 11. In a state that the mask 12 is formed, an ion implantation of oxygen ions or nitrogen ions is totally performed as shown by arrows 13 and the regions other than the FET operating region of the film 11 are converted into an insulator and are used as insulating regions 11a. Thereby, steps are never generated on the film 11 at all and the FET operating region 11b separated individually by the regions 11a is formed. Moreover, each electrode, a wiring and an insulating film are formed on the region 11b to form a FET. Thereby, at the time of an electrode wiring treatment and the like, the generation of steps is eliminated and the cutting due to steps of the wiring can be prevented.
