Title: Collating method for password number of identification card system and card collating device
Inventor: ISHIKAWA AKITAKE
IPC: G06Q40/02
Filed: 1985-10-21
Abstract: PURPOSE:To decrease remarkably a chance by which a password number is stolen, by generating a coincidence signal, if a character string of the inputted, password number coincides with one of available character strings peculiar to a card user, such as a telephone number, a data of his birth, registered in advance, when the inputted passwords are not coincident with each other. CONSTITUTION:When the data of birth of a card holder is October 8, 1950, the character string which is stored in an available character string area becomes 19501008. In this case, for instance, a person who does not know a correct password number (1908) knows the data of birth of the card holder, estimates the password number from its numerical value and inputs in incorrect number 5010. In this case, the password does not coincide, an operation for collating the available character string is executed, and a character string 5010 coincides, therefore, a coincidence signal is generated. If an incorrect password number is estimated from the telephone number, its comparison is executed in the same way, and after all, coincidence signal is generated.

Title: Production of pectic acid
Inventor: HATANAKA CHITOSE
IPC: C08B37/06
Filed: 1986-10-02
Abstract: PURPOSE:To produce industrially pectic acid by selectively converting methoxycarbonyl groups of the side chains of pectin into carboxyl groups without causing degradation of the chemical structure of its main chain, by saponifying pectin under specified reaction conditions and treating the saponificate with an acid. CONSTITUTION:Powered or slurried pectin is saponified at a about -2-10 deg.C in the presence of about 0.8-1.6mol, per mol of uronic acid residues of pectin, of an alkali (preferably, NaOH or KOH) in a lower alcohol such as an about 40-90wt% aqueous alcohol solution (preferably, a lower alcohol such as methanol), and the obtained saponificate is treated with an acid (e.g., hydrochloric acid or sulfuric acid). According to the above process, pectic acid can be produced as a result of the selective conversion of methoxycarbonyl groups of the side chains of pectin into carboxyl groups without causing undesirable side reactions such as cleavage of the main chain of a pectin molecule. Further, this process can provide a highly pure product because impurities adsorbed by the pectin powder can be easily removed during said treatment and is industrially advantageous because masstreatment is easy.
