Title: Pole provided with damping device with reaction preventing mechanism
Inventor: ICHIHARA TERUJI
IPC: E01F9/631
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To damp impact onto a road sign pole in all directions by filling spherical bodies capable of absorbing the reactional force of a spring and also capable of easily moving in a clearance inside a rubber elastic body cover. SOLUTION: In a ring universal joint located inside a spring 3 passed through a mounting clamp 1 on a fixed side and a clamp 2 on a pole side, a reactional force against a spring 3 is produced by the tightening of it with a nut 14 and a pole is held vertically or horizontally. When the pole is impacted, it is inclined to the direction of a position opposite to the impact position. When the impact is removed, it is returned immediately to the vertical or horizontal position by the reactional force of the spring 3. However, because multiple spherical bodies 5 capable of absorbing the reactional force properly are filled in a clearance inside a sealed rubber elastic body cover 6, the pole is operated smoothly while the reactional force of the spring 3 is sealed and suppressed so as to hold itself vertically or horizontally.

Title: Nucleic acid treatment agent composed of oligothiophene derivative
Inventor: PAUL KOOBANKU
IPC: C07D409/14
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To obtain a nucleic-acid treatment agent which is easily synthesized, which acts on a nucleic acid such as DNA or the like so as to be bonded and which can detect its bonded result simply by a method, wherein the nucleic-acid treatment agent is composed of an oligothiophene derivative expressed by a specific formula. SOLUTION: An oligothiophene derivative, which constitutes a nucleic-acid treatment agent and which is expressed by a specific formula, is dissolved in hydrochloric acid, it is then dissolved easily in a buffer whose pH is close to neutral, and it acts on a nucleic acid such as DNA or the like so as to be bonded. That is to say, when the oligothiophene derivative is treated with the hydrocloric acid, its protecting group (THP: tetrahydropyran) is desorbed so as to be changed into protons. It is supposed that the derivative generates N-methylammonium methyloligothiophene, and it is interpreted that the derivative is bonded to the nucleic acid such as DNA or the like via a positively charged ammonium substituent.  In the manner, when the nucleic- acid treatment agent is used, ammonium-substituted oligothiophene (polythiophene) functions as a marker to detect the part in which it is bonded to the nucleic acid and also as a marker to detect its bonding.
