IPC: H02P25/06
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To compensate a control deviation part caused by a thrust fluctuation, etc., by a method wherein the control is performed while values which are obtained by referring to a reference table successively are added to the control deviation. SOLUTION: A reference table Km is stored in a memory 3 and is successively referred to by a table referring means 2. When a motor is driven, the table is referred to in accordance with position information (p) obtained by a position detector 10 and a correction factor (k) at that position is obtained. That is, the position information (p) is converted into a value which is integer times of the pitch δ of the table and the value is used as an offset from the leading end of the reference table in the memory to obtain the correction factor (k) at the present position. A control deviation is calculated by a control arithmetic means 4 and the obtained correction factor (k) is added to the calculation result. Then, a result after a compensation calculation such as PID is inputted to a D/A converter 7 as a control input to drive the motor.

Filed: 1990-11-30
Abstract: PURPOSE:To accomplishing a multiple beam simultaneous formation method suitable for scannings such as linear scanning and sector scanning by arranging a first delay section and a plurality of second delays sections to vary a delay time given by the second delay sections in a phasing processing of one received signal. CONSTITUTION:A first phasing of a received signal is performed with a first delay section 2. By the phasing, a virtual ultrasonic beam bm1 is formed at an optional location. Then, the received signal subjected to the phasing with the first delay section (b) is given a delay with the second delay section (a) and the second delay section (b). In a fine angle sector method, a new delay is applied with the two second delay sections so that the virtual ultrasonic beam bm1 set with the first delay section is distributed horizontally at a fine angle theta to form actual ultrasonic wave beams bm2 and bm3. As the delay time to be given with the second delay sections (a) and (b) is variable in a phasing processing with respect to one received signal, the value of theta can be varied within one received signal. This enables the realizing of both of a multiple beam simultaneous formation method suitable for linear scannings and that suitable for sector scannings with a handy hardware construction.

Title: Mobile communication authentication method
Inventor: OHASHI MASAYOSHI
IPC: H04L9/06
Filed: 1994-12-05
Abstract: PURPOSE:To provide a mobile communication authentication method which can attain the roaming among the systems that have different random number transmission bit lengths in plural communication networks. CONSTITUTION:The correctness of a mobile device defined based on the same algorithm as that set between a home network and the mobile device is shown between a roaming destination network and the mobile device so that the mobile device has an access to the roaming destination network to perform the communication as long as plural mobile communication networks that are originally prepared exist. In such an authentication sequence, the random number transmission bit length of the roaming destination network is smaller than that of the home network. Under such conditions, the random number transmission bit length is increased up to the bit length of the home network by means of a magnification function. Thus at least the random number and the arithmetic result set before the bit length of the roaming network is increased are acquired by the magnification function. Thus the communication is certified among plural mobile communication networks of different authentication random numbers and different arithmetic results.
