Abstract: PURPOSE: To obtain a lubricating oil product having high pour point and low viscosity index by the ordinary dewaxing technique, by isomerizing the wax to a specific conversion level in the presence of a catalyst, then rectifying the same, and dewaxing the same by a solvent.  
     CONSTITUTION: The wax is isomerized to a conversion level satisfying that a ratio of unconverted wax/uncoverted wax + dewaxed oil) is less than about 40% (preferably about 20 to 30%), on an isomerization catalyst (for example, the VI, VIII group metal or the like supported by alumina fluoride), in an isomerization device. Then the whole product from the isomerization zone, is rectified to the lubricating oil which boils within a range of lubricating oil boiling point, and the fraction is dewaxed by the solvent, to obtain the lubricating oil base stock or blending stock of not more than -21°C of pour point and not less than 130 of viscosity index. The isomerization process is performed under the conditions that the temperature is about 270 to 400°C, the pressure is 35.15 to 210.9kg/cm 2 , the gas velocity is 1000-10000SCF/b, and the space velocity is 0.1 to 10v/v/hr.

Title: Modification of solder deposition composition
Inventor: IRIE HISAO
IPC: H05K3/24
Filed: 1992-11-04
Abstract: PURPOSE:To form a solder layer of uniform thickness on a pad of a printed board by modifying a solder deposition composition that is composed mainly of organic plumbate and tin powder and then by causing a lead film to be deposited on the surface of the tin powder by solid-solid diffusion. CONSTITUTION:When a solder deposition composition, chief of which are organic plumbate and tin powder, is heated at 100-180 deg.C for 0.5-20 minutes, the organic plumbate dissociates and generates lead ions and then the ion exchange reaction is caused between the lead ions and metal tin and as a result, meal lead is deposited. The metal lead diffuses into the tin powder and then a tin-lead allay is formed on the surface of the tin powder. The allay does not melt and all the reactions progress in solid state. Therefore, there is no reduction in the diffusion speed that could be caused by the fact that the solid-liquid diffusion partially occurs and the tin powder in the composition is coated with metal lead since there is not such thing occurring that metal grains melt and are combined into one. By this method, a solder layer of uniform thinkness can be formed on a pad.
