Title: Connecting and forming method for thermoplastic high molecular molded product
Inventor: NISHIKAWA KENJIROU
IPC: B29C53/00
Filed: 1979-03-13
Abstract: PURPOSE: To improve productivity and to improve a connecting strength, a forming finish, etc., by induction-heating a mold by means of an inductor.  
     CONSTITUTION: A thermoplastic high molecular molded product 4 inserted between a mold 1 formed monolithically with a water cooling jacket 2 and a smoothed inductor 3 is pressed thereat, and with it an alternating field is emanated at the inductor 3. The mold 1 is induction-heated, whereby the molded product 4 is connected or formed in correspondence with the shape of the mold 1. For example, in the case of two pieces of the molded products being connected together, the inductor 3 ceases to be excited at the stage where the molded products 4 are welded together by induction-heating, the mold 1 being cooled by flowing water into the water cooling jacket. The molded product 4 so processed ceases to be pressed at the stage where a fusion melting of the molded product 4 is hardened.

IPC: B01D61/12
Filed: 1984-02-20
Abstract: PURPOSE:To separate and concentrate effectively an alcohol from an aqueous solution of the alcohol to the permeated water side at a relatively low energy cost, by feeding the aqueous solution of the alcohol containing a soluble organic substance other than the alcohol to a reverse osmosis membrane of relatively low desalination ratio under pressure. CONSTITUTION:An alcohol is separated and concentrated from an aqueous solution thereof 2. In the process, a soluble organic substance 3, e.g. raffinose or lactose, other than the alcohol is present in the above-mentioned aqueous solution 2, which is fed to a reverse osmosis membrane 5 of <=90%, preferably 10- 80% desalination ratio under preferably <=20kg/cm<2> pressure to separate and concentrate the alcohol 6 on the permeated water side. The alcohol can be concentrated under a lower pressure by this method than by the well-known method, and this method is advantageous to energy cost. The unpermeated water side 7 is circulated, and a concentrated solution of the alcohol 6 is obtained on the permeated water side. Thus, the recovery ratio of the alcohol is high, and an aqueous solution of a lower alcohol in a low concentration at which the distillation method cannot be applied can be concentrated to a concentration at which the distillation method is applicable at a low cost.

Filed: 1986-02-14
Abstract: PURPOSE:To improve the efficiency of a lead frame by a method wherein the longitudinal and lateral measurements of the lead frame are reduced as going nearer to the four corner parts of an element mounting part, each lead is deviatively arranged toward the tip direction of the lead, the tolerance limit of the angle of disposition in tension of the fine metal wire against the leads is made wider in the vicinity of the corner parts, and the mountable range of an element chips is increased. CONSTITUTION:The four sides of an element mounting part 1 are not formed rectilinearly, and the distance of each side from the horizontal center line LT and the vertical center line LY, passing the center point C of the element mounting part 1, is made in such a manner that it becomes smaller by stage as going nearler to the corner parts of the element mounting part 1. Also, corresponding to the above condition, each lead 2 is constituted in such a manner that it is deviated by a very small measurement toward the direction of the tip of the lead as going nearer to the corner parts of the element mounting part 1. Accordingly, when a fine metal wire 5a is going to be connected to the lead 2a, the maximum angle of disposition in tension of theta1 required to secure the prescribed margine (t) between said fine metal wire 5a and the adjoining lead 2b is to be made larger than the angle of disposition in tension heretofore in use. As a result, the range for connection of the fine metal wire 5 can be increased even when a small element chip is mounted.
