Title: Controller for motor
Inventor: TADA SHIGEHIRO
IPC: H02P7/292
Filed: 1989-11-17
Abstract: PURPOSE:To prevent a transient overcurrent by applying phase control input of a thyristor power converter from another function generator during control insensitive zone period until a current control is established at the time of starting a motor to control to predict a motor current. CONSTITUTION:A set value of a function generator 6 normally becomes a rated current value of a motor, and the output of a phase control AMP 4 becomes a value capable of generating an output voltage necessary to supply a rate current at the time of stop of the motor. The output of the generator 6 supplies a starting current of a rated value or lower to the motor input to a power AMP 3 through a switching contact 5a, and an input from a current control AMP 2 during no control period until a current detector detects a current feedback C-FB is interrupted by a switching contact 5b. Thus, the motor can be started stably by a current near a rated value without transient overcurrent.

Title: Object detector
Inventor: NAKANO MASAHIRO
IPC: G01V8/12
Filed: 1992-11-09
Abstract: PURPOSE:To accurately detect an object even when infrared rays generated by some causes act as an external disturbance in an onjeat detector using the infrared rays. CONSTITUTION:After a switch SW has been turned on, a microcomputer 22 does not make a light-emitting element 6a emit light for a definite time, and it learns the generation pattern of light detected by a photodetector 6b at this time. The light which has been detected by the photodetector 6b when the lightemitting element 6a does not emit light is not reflected light reflected when radiated light from the light-emitting element 6a hits an object (a human being), and it is external disturbance light generated by any cause. Then, the microcomputer 22 makes the light-emitting element 6a emit light so as to coincide with the learnt generation pattern of external disturbance light. As a result, the external disturbance light does not coincide with the light emitted by the light-emitting element 6a. Then, the microcomputer 22 judges that the object exists when the photodetector 6b has received the reflected light with reference to the light emitted by the light-emitting element 6a.

Title: Ciphering method, deciphering method, and authentication method
Inventor: NAKAUCHI SHUNSAKU
IPC: G09C1/00
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To simply cipher and decipher, moreover, make it difficult to decipher by selecting a specific number from binary numbers having the same number of bits as the number of digits or characters for adopting the number as a secret key, and ciphering by combining a transposition method by this number with XOR (exclusive-OR) technique. SOLUTION: When data to be ciphered have been put in a specific order into positions where 1 (or 0) of bit of a binary number as a secret key is standing and all the positions with 1 (or 0) are filled with the data, positions with 0 (or 1) are filled with the remaining data in a specific order. And, the sum of the cipher text ciphered by the data or transposition and a secret key, or exclusive-OR are combined in multi-stages. Namely, the transposition is repeated plural times by using the same secret key to make the cipher complex, and an XOR of the transposed number and key code is adopted to increase the cipher in the strength further. Thus, a number ciphered by transpositions is ciphered more and is increased in the cipher strength.
