Title: Enciphering method, and decoding method and device
Inventor: TAMURA HIROYUKI
IPC: H04L9/26
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To provide an enciphering method and decoding method and device having higher secrecy by setting a cipher use mode. SOLUTION: A key data storing part 105 stores a cryptographic key including the cipher use mode. A cipher use mode selection signal generating part 104 reads the cryptographic key from the part 105 and outputs a selection signal selecting the cipher use mode. A cipher use mode controlling part 102 sets the cipher use mode of a cipher/decode algorithm part 101 by the selection signal. An encipher/decode processing part 103 converts plaintext or cryptography from a data inputting and outputting part 106 into the data of cryptography or plaintext according to the above setting and outputs the data. Secrecy can be improved because a cipher operation mode is set in addition to the cryptographic key of encipher/decoding by including the information of the cipher use mode (chain technique) in the cryptographic key.

Title: Drive circuit for ultrasonic motor
Inventor: FURUKOSHI HIROYUKI
IPC: H02N2/00
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To smoothly stop an ultrasonic motor with stability, even if a direct- current voltage supplied from a specified power supply becomes unstable, and to prevent audible noise produced when the ultrasonic motor is stopped. SOLUTION: When an ultrasonic motor is stopped, boosted voltage outputted from a voltage generating circuit 38 is reduced gradually and furthermore the drive frequency of the ultrasonic motor is increased gradually. As a result, the frequencies of alternating-current voltage outputted from a phase-A amplifying circuit 42 and alternating-current voltage outputted from a phase-B amplifying circuit are gradually increased. (The number of revolutions is gradually reduced). Therefore, the amplitude is gradually reduced with stability, even of battery voltage becomes unstable. For this reason, since the ultrasonic motor is stopped gently with stability, audible noise can be prevented from being produced.
