Patent NO-116730-B (NO)
Inventor: WACHHOLTZ F
IPC: C08L67/08
Filed: 1965-08-05
Abstract: A fatty acid ester resin containing free carboxyl groups is obtained by reacting at most 65% of the carboxyl groups of a poly-carboxylic acid or intramolecular anhydride thereof with a hydroxy-containing fatty acid ester of an aromatic compound having a plurality of hydroxyl functions, either as hydroxy groups or as epoxy groups, and no polyester group.  Preferred hydroxy-containing fatty acid esters are partial fatty acid esters of styrene-allyl alcohol copolymers, and partial fatty acid esters of epoxy resins, e.g. partial fatty acid esters of polyglycidyl-polyhydroxy - ethers of polyhydric phenols. The polyhydric phenol may be bisphenol A which may be reacted with epichlorohydrin to form the epoxy resin.  In the examples, linseed oil fatty acid and coconut oil fatty acid are the fatty acids employed and the polycarboxylic acids or anhydrides employed are phthalic, maleic and trimellitic anhydrides and itaconic and succinic acids.  A binding agent, dilutable with water, may be prepared by neutralizing at least 60% of the free carboxyl groups of the fatty acid ester resin, for instance with aqueous solutions of sodium hydroxide, ammonia, 2-amino-1 butanol, tri-ethylamine, triethanol amine or morpholine. To increase the solubility a lyotropically active agent, e.g. butanol, pentanol or butoxyethanol, may be added.  The binding compositions may be used as such or mixed with other known binder compositions.

Title: Gene expression system autoregulated by medium biotin
Inventor: SHIUAN DA-WEI
IPC: C12N15/66
Filed: 1995-12-21
Granted: 2001-05-01
Abstract: Transcription in E. Coli biotin operon is regulated by the repressor (birA gene product) and the corepressor (biotinyl 5'-adenylate). The present invention utilizes the operator-repressor interaction of biotin to design an autoregulated gene expression system in which the host is a bio operon deletion mutant of E. coli, R901 (ΔbioA-D). The gene expression system can thus be turned on by the deprivation of medium biotin during cell growth. The expression vectors were constructed by assembling the DNA fragment containing the regulatory region of E. coli biotin operon, the universal ribosomal-binding region and the strong transcription terminator rrnBT1T2. The promoter region was modified by site directed mutagenesis to create promoters of varied strength. The feasibility of this system was examined using various marker genes including E. coli birA gene, T7 RNA polymerase gene and the yellowfin porgy growth hormone gene.

Abstract: A charged particle beam exposure method, wherein a charged particle beam is shaped based on pattern data and the shaped charged particle beam is irradiated to a desired location on a sample, the method comprises the steps of: introducing ozone gas into a chamber through which the charged particle beam is passed, shaped and deflected so as to be irradiated to the desired location; and maintaining the ozone gas concentration in the chamber so that the concentration downstream along the beam is higher than the concentration upstream along the beam. A charge-up drift due to a contamination material from a resist on a wafer can be avoided by the ozone self cleaning. The ozone oxidation does not occur at the upstream chamber where lower ozone concentration but lower contamination.
