Title: Electroconductive treatment agent for paper
Inventor: TAKAHASHI FUMIHARU
IPC: D21H19/24
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain the subject agent for making paper highly electroconductive by including, as the active ingredient, polyvinylimidazoline as a high-molecular- weight electrolyte. SOLUTION: The agent is composed of polyvinylimidazoline, which is normally obtained by reacting a nitrile-containing polymer, e.g. a meth(acrylonitrile) polymer, with a 1,2-diamine, e.g. ethylenediamine. A crosslinked polyvinylimidazoline may be used. When the treatment agent is not sufficient in sustainability, it is recommended to increase its viscosity by a crosslinking agent, e.g. carboxylic acid (e.g. acetic acid). The treatment agent is obtained by, e.g. diluting polyvinylimidazoline with water or an organic solvent compatible with water. It is preferable to spread the agent over paper at 0.05 to 10 g/m2.

Title: Checking method for punch hole of magnetic card
Inventor: MUKODA NAOKI
IPC: G11B21/20
Filed: 1991-12-09
Abstract: PURPOSE:To detect the presence or absence of a punch hole even though the punch hole is filled with a punched piece by recording previously a magnetic code at the track position where the punch hole is formed. CONSTITUTION:The magnetic codes 6 are previously and equidistantly recorded at the track position where a punch hole 2 is formed on a magnetic card 1. The card 1 put into an equipment is reproduced by a magnetic head 5 and the hole 2 is checked. That is, no code 6 is detected at the position of the hole 2 and therefore the presence of the hole 2 is confirmed. Furthermore the probability of coincidence is small between the direction of the code 6 of a punched piece 7 and the direction of the original code 6 even if the piece 7 is put into the hole 2 and fixed there. Meanwhile a gap 8 is produced between the hole 2 and the piece 7 and causes the disturbance of the detection signal. Thus the presence of the hole can be decided.
