Patent JP-S60144708-A (JP)
Title: Frp optical fiber core
Inventor: KAGEYAMA GAKUSHI
IPC: C08F283/01
Filed: 1984-01-09
Abstract: PURPOSE:To enable prevention of embrittleness of a buffer layer and holding of creep resistance by limiting the consitituting ratio of unsatd. polyester or opoxy acrylate and a specific amt. of acrylate and/or methacrylate as well as a crosslinkable material consisting of a hydrocarbon monomer for an FRP coating layer. CONSTITUTION:An FRP coating layer is constituted of the matrix consisting of 90-30wt% unsatd. polyester or epoxy acrylate, 100-30pts.wt. acrylate and/or methacrylate and 10-70wt% crosslinkable material consisting of 0-70wt% hydrocarbon monomer. The constituting ratio of the unsatd. polyester or epoxy acrylate and the crosslinkable compd. are 90-30wt% and 10-70wt%, more preferably 80-50wt% and 20-50wt%, respectively. If the unsatd. polyester or epoxy acrylate is >=90wt%, the viscosity of the resin increases, the workability in the stage of forming FRP is poor and the performance such as heat resistance decreases considerably and therefore such ratio is undersirable.

Title: A method for the selective cleavage of fusion proteins
Inventor: VERTESY LASZLO
IPC: C07K14/62
Filed: 1989-11-02
Abstract: Polypeptides or proteins such as, for example, insulins or de-B<3><0>-insulins - especially human insulin or de-B<3><0>-human insulin - are prepared by enzymatic cleavage, using a trypsin-like endopeptidase, of specific fusion proteins which can be obtained by genetic manipulation and which contain the residue of a peptide-like alpha -amylase inhibitor in the molecule.

Abstract: MULTIMODE HORN ANTENNA            Abstract of the Disclosure A horn antenna is described including a funnel-shaped coupler with a port at the narrow end of the coupler adapted to excite a symmetrical waveguide mode in the coupler and a plurality of side wall input ports adapted to excite at least two difference waveguide modes.  The port at the narrow end of the coupler is coupled by a first step to a smaller diameter cylindrical section capable of propagating the dominant symmetrical mode.          A larger diameter cylindrical section is coupled to the larger end of the coupler by a second step.  A ring divides the larger diameter cylindrical section into two parts.  The first and second steps and the dimensioning and placement of the ring are arranged so that the two difference mode radiation patterns have essentially the same combined beam width or pattern envelope as the symmetrical mode radiation pattern.
