Abstract: The invention provides a novel process for the manufacture of [2,3-trans]-tetrahydro-5-hydroxy-3-hydroxymethyl-2-phenylfurans of the formula IIa, useful as intermediates in the production of novel (4-phenyl-1,3-dioxan-cis-5-yl)alkenoic acids of the formula I in which Ra and Rb are independently hydrogen, alkenyl, alkyl, halogenoalkyl, pentafluorophenyl, aryl or aryl-(1-4C)alkyl; or Ra and Rb together are polymethylene; Rc is hydroxy or (1-6C)alkanesulphonamido, A is vinylene, n is 1, Y is polymethylene, and benzene ring B bears various optional substituents. The compounds of formula I are obtained by the reaction of an aldehyde of formula II with an ylid to give an erythro-diol of formula III which is then cyclised to the required dioxane derivative of formula I. The aldehydes of formula II are obtained from the corresponding lactols of formula IIa, which are themselves obtained with the correct trans-stereochemistry by the inventive process using two selective reductions of a trans-phenylparaconic acid of formula V. The compounds of formula I are useful as therapeutic agents.

Abstract: Two articles (11, 12) are joined together with the aid of a gasket (3) comprising a laminar conductive polymer heating element (31). The gasket is placed between the articles and is heated by passing current through the heating element. Preferably, the articles are composed of a polymeric material and become fused to the heating element, or directly to each other through holes in the gasket. In a preferred embodiment, the gasket (3) has a wedge-shaped cross-section.

Abstract: 본 발명은 다중 특성을 갖는 중합체를 기초로한 분산된 토너입자를 함유하는 전자 사진상 현상용 액체 토너에 관한 것이다. 
     이들 토너입자는 실온 이하의 Tg 를 갖는 열가소성 수지상 코어를 포함하고 있으며, 이 코어는 4.5 미만의 pKa 를 갖는 유기산 함유 잔기가 공유적으로 결합되어 있는 양친매성 공중합체 입체 안정화제에 화학적으로 결합되어 있으며, 이러한 유기산은 pKa 값이 4.5 이상인 유기산으로 부터 유도된 금속 비누 화합물에 화학적으로 결합되어 있다. 
     상기 방법으로 제조된 토너 입자는 높은 전하/질량(mass)의 유리한 특성 및 양호한 전하 및 분산 안정성을 갖고 있다.

Title: Isolation forming method of semiconductor

Abstract: A buffer oxide layer is formed on a  semiconductor  substrate of a first conductive type  and  polysilicon  and  nitride  layers sequentially formed on the buffer oxide layer. Then, part  of  the nitride layer formed on a predetermined element insulating  region is selectively removed, and  a  polysilicon  layer  of  which  the thickness is similar to that  of  the  nitride  layer,  is  formed between the inner  side  walls  of  the  remaining  nitride  layer portions. The polysilicon layer is oxidised and then the remaining nitride layer and polysilicon layer are removed, to  thereby  form an insulating oxide layer without affecting the substrate.  Bird's beak phenomenon and stress on substrate are reduced in  insulating region.
