Title: Antenna for vehicle
Inventor: TAKIZAWA MAREO
IPC: H01Q1/36
Filed: 1988-06-24
Abstract: PURPOSE:To provide an antenna even along the curved surface of a bending part of a vehicle body by arranging plural bar-shaped cores in the lengthwise direction and winding a coil around them throughout in the lengthwise direction so that they can be bent. CONSTITUTION:Plural bar-shaped cores 11, 12-1n like ferrite cores are arranged in the lengthwise direction and a coil 2 is wound around them throughout in the lengthwise direction to constitute an antenna A. A cable 4 is led out from the coil 2 of the antenna A and is connected to a receiver. Cores are connected by the coil 2 and the outside peripheral surface is coated with an insulator 3. A flexible synthetic resin may be used as the insulator 3, and a thermally contractible tube or a thin formed material can be used. Since the antenna A constituted in this manner has bar-shaped cores 11, 12-1n merely connected to one another by the coil 2, bar-shaped cores have a slight flexibility and form a bend as the whole or partially.

Title: Production of oligopeptide
Inventor: YAMANE KUNIO
IPC: C12N1/21
Filed: 1984-07-27
Abstract: PURPOSE:To enable the secretion and production of an oligopeptide from a bacterial cell, using a vector prepared by introducing a DNA coding the objective oligopeptide to a plasmid containing a leader gene and an alpha-amylase structural gene. CONSTITUTION:A DNA coding the objective oligopeptide (e.g. angiotensin I, bradykinin, insulin, etc.) is linked to an alpha-amylase gene containing a leader gene and an alpha-amylase structural gene, to effect the secretion of the fused protein consisting of alpha-amylase and the oligopeptide from the bacterial cell. In the conventional process, the produced oligopeptide is retained in the bacterial cell and accordingly it is necessary to disintegrate the bacterial cell resulting in the difficult purification. In contrast to the above, the oligopeptide is secreted from the bacterial cell in the present process, and the separation and purification of the objective compound can be carried out easily.
