Title: Production of powdered solder
Inventor: MITSUI TOMOKUNI
IPC: B23K35/40
Filed: 1990-03-27
Abstract: PURPOSE:To easily produce powdered solder capable of applying the reflow method by adjusting the atmosphere on the cooled bottom so that the oxygen content of the powdered solder takes a specified ppm. CONSTITUTION:A container 1 rotated by a rotation shaft 2 at a high speed and the cooled liquid 5 in the container is formed by rotational centrifugal force in the form of a wall surface. The molten solder is injected from a nozzle 3 to this place. The continuous flow of the molten solder is broken up into particles when or before it comes in contact with the cooled liquid surface. The particles are cooled and solidified in coolant 5 to produce powdered solder. Then, the atmosphere on the cooled bottom surface is adjusted so that the oxygen content per g of the powdered solder takes 150ppm. Liquid containing halogen compound having a boiling point 100 deg.C is used as cooling liquid. In this way, the oxygen content per unit weight of the powdered solder can be inhibited under a prescribed amount.

Title: Centrifugal concentrator
Inventor: TOKUNAGA KIYOHIKO
IPC: B04B1/02
Filed: 1980-06-13
Abstract: PURPOSE: To facilitate the continuous operation of material-feed and concentrated matter-recovery, in the disposal of sewage or the like, by providing a concentrating rotary cylinder with a passage for feeding suspension to be disposed and a passage for discharging an effluent collected at the side of a rotary shaft.  
     CONSTITUTION: A rotary cylinder 1 is provided with a partition wall 3 which divides a treating space S inside the cylinder 1 into a concentrating space S 1  and a concentrated matter-discharging space S 2 . The partition wall 3 is provided with a  passage R which carries the concentrated matter from the space S 1  into the space  S 2 . The open end of a passage R 3  for recovery of the concentrated matter in the  space S 1  is constructed in a manner such that its position can be freely changed  along the radial direction of the rotary cylinder 1. Consequently, an effluent and the  concentrated matter can be recovered continuously, even when the suspension is  continuously fed. Besides, the recovery amount of the concentrated matter can be  controlled because the position of the open end of the passage R 3  can be changed along the radial direction of the cylinder 1. As a result, the concentrated matter can be recovered while maintaining its concentration at a desired level, even when the concentration of solid content in the suspension is varied.

Title: Cooling device
Inventor: KASHIWABARA IKUTA
IPC: F25D17/02
Filed: 1988-04-04
Abstract: PURPOSE:To economically cool thin sheet material, and maintain good operating conditions for a long period of time by connecting a normal temperature water pipe to at least one of chilling rolls that are located upstream in the conveying direction, and connecting a chilled water pipe to the other chilling rolls. CONSTITUTION:Two or more chilling rolls 2A, 2B, 2C and 2D are arranged parallel on the way of conveying a zonal printed matter to cool the zonal printed matter. The chilling roll 2A, located upstream in the conveying direction, is connected to a normal temperature water pipe 3, and the chilling rolls 2B, 2C and 2D, located downstream, are connected to a chilled water pipe 4. Chilled water is supplied only to the chilling roll 2B, 2C and 2D, and normal temperature water to the chilling roll 2A. The calorie to be cooled by the chilling roll 2A to which normal water is supplied is about a half of the total calorie to be cooled by the whole chilling rolls so that the cooling load for chilling water decreases to half by using normal temperature water. Therefore, cooling of the zonal printed matter 1 can be economically performed because the creation of heat resistance zone inside the chilling rolls is prevented and good operating conditions are maintained for a long period of time.
