IPC: C07C67/00
Filed: 1981-07-30
Abstract: PURPOSE:To obtain the titled compound, by precipitating bisphenol A from a reaction mixture of acetone and phenol, adsorbing the separated filtrate on a specific adsorbent, washing the adsorbent with a specified cleaner periodically, recycling it to the reaction system. CONSTITUTION:Acetone is reacted with phenol in the presence of a catalyst of strongly acidic cation exchange resin, to give a reaction mixture, which is cooled, so that bisphenol (BPA for short) is precipitated as crystal of an addition product of BPA with phenol, filtered and separated. The separated mother liquor is brought into contact with an adsorbent of silica-alunina so that a coloring component is adsorbed and removed. The adsorbent having adsorbed the coloring component is periodically washed by passing a silica-alumina mixture through it, the coloring component is desorbed, and the adsorbent is recycled to the reaction system. EFFECT:The coloring component in the filtrate is removed efficiently, and the  adsorbent is regenerated well. USE:A raw material for polycarbonate resin, epoxy resin, etc.

Title: Manufacture of constituent of micro-machine
Inventor: SKAPA HELMUT
IPC: B81C3/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To improve the reliability on constitution and operating performance of a micro-machine, by maintaining an insulating layer in a second extent in such a state that the layer is protected by a conductor layer at the formation of a moving element in a first extent. SOLUTION: In a second extent III, a contacting element 20 which is electrically connected to a conductor path 3 through a contact plug 60 is separately formed. When the element 20 is formed, the metallized pad 7 of the element 20 is used as a mask at the time of performing plasma etching on second trenches 9' which surround the contacting element 20 for a bonding pad 20 in the second extent III. Since any photo-process becomes scarcely possible at this point of time due to the very fine structure of a micro-machine, this is fit for the purpose. Therefore, an etching process is performed without using any photo-mask and, in addition, the extent of a sensor core can be protected from the etchant when the pad 7 is formed in a thick cap or encapsulated.
