Title: Information recording medium and its recording and reproducing method
Inventor: KUROIWA MASAO
IPC: G11B5/02
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an information recording medium which allows the setting of intrinsic information on information recording media so as to vary the information from each other between the respective media and has excellent characteristics, such as workability to the information recording media, degree of freedom in setting of forming points and reading and reproduction characteristics of the intrinsic information and its recording and reproducing method. SOLUTION: Magnetic information patterns 3 are formed on at least part on a base material 11 as magnetically recordable magnetic codes consisting of a magnetic recording material having high coercive force with which writing by a magnetic head at ordinary temp. is substantially impossible and having low Curie point at which writing by the magnetic head by heating is substantially possible. Magnetic bars (magnetic code) 3a are arranged at the same and equal intervals at the time of production. As a result, the cost is reduced and the production efficiency is enhanced. Reading by using magnetic developers, etc., is non-discriminatable in a magnetization direction and is difficult. The execution of ternarized information recording with one magnetic bar (magnetic code) is made possible by using the non-magnetized magnetic bars (magnetic codes).  The recording density of the medium is thus increased.

Abstract: PURPOSE:To improve volume efficiency and obtain a chiral enol in a small amount of an expensive amine to be used by reacting a prochiral cyclic ketone having a symmetry plane with an optically active amine or a lithiated substance thereof in the presence of a lithiating agent. CONSTITUTION:A prochiral cyclic ketone having a symmetry plane, preferably 5-7C cyclic ketone is reacted with an optically active amine expressed by formula I [R<1> is alkyl, aralkyl, alkoxyalkyl or aryl; R<2> is H, alkyl or aryl; R<3> is H, alkyl, dialkylamino or formula II (X is alkylene optionally linked through N); at least one carbon atom marked with * and ** is asymmetric carbon atom] or lithiated substance thereof in the presence of a lithiating agent, e.g. alkyllithium. Since the lithiating agent provides repeated generation of the lithiated substance in the reaction system to efficiently advance the reaction, the presence of the amine in an amount of 0.1-0.5 equivalent based on the cyclic ketone and the lithiating agent in an amount of 1.5 equivalents based on the cyclic ketone is preferred.

Filed: 1993-02-26
Abstract: PURPOSE:To automatically measure the bit error rates of a ratio transceiver device and a radio MODEM by calculating the worst value phase in the least pull-in phase frequency. CONSTITUTION:A distributer 7 is provided together with a 2nd demodulator 12, a phase detector 8, and a computer device 9. The output received from a receiver 4 is divided into two pieces by the distributor 7, and the reproduced carrier signals 31 and 32 acquired from a 1st demodulator 11 and the demodulator 12 are supplied to the detector 8. Thus a relative modulation phase difference is detected based on an optional pull-in phase of the demodulator 12. Based on this detected phase difference, the value of a variable attenuator contained in a noise adding circuit 5 is changed at a fixed rate by the computer device 9. Thus the worst phase value is controlled by the overall phase evaluation, and a bit error rate is automatically measured. In such a constitution, the time required for measurement of the bit error rate can be reduced and furthermore the human errors in the statistic processing can be eliminated.
