IPC: G06F21/31
Filed: 1991-12-24
Abstract: PURPOSE:To provide a method for restoring a lost password and a method for confirming an inputted password without impairing safety nor easiness. CONSTITUTION:A password restoration center 4 which restores the password is provided and a user ciphers his or her password by using the open key of the password restoration center 4 and then stores it. If the password is lost, the user indicates the ciphered and stored password and requests the password restoration center 4 to restore the password. The password restoration center 4 after certifying the user 1 deciphers the ciphered password by using a secret key and informs the user 1 of the result. Then the ciphered password is stored on a portable medium and identification information, etc., the user 1 is ciphered at the same time. The ciphered password is used to confirm whether or not the inputted password is correct.

Abstract: PROBLEM TO BE SOLVED: To perform current limitation control stably and quickly to the change of an operation current value, in full range of operation range, by performing the gain compensation using the primary formula of limited frequency, for the quantity of change of the limited frequency to a motor for a compressor. SOLUTION: A limited frequency computing unit 11 computes stageless limited frequency F1td-f(k) by the sampling value I(k), the command frequency Fset(k) (=Fset), and the tolerable current value Iset(k) (=Iset) from a current measuring instrument 10, and the limited frequency being the last control operation result from a limited frequency storage 12. A gain compensator and processor 18 performs gain compensation by the quantity dFdef-f(k) of the change of limited frequency and the limited frequency F1td(k) stored in the limited frequency storage 12. This computes the quantity dFdef-g(k) of the change of the compensation frequency limitation. Hereby, gain varies with operation frequency can be obtained, and proper current limitation control can be performed.

Abstract: PROBLEM TO BE SOLVED: To reduce routing of wiring connection of a semiconductor component and to decrease an erroneous operation by modularizing a circuit for serially connecting first and second diodes and second switching element. SOLUTION: A chip of switching elements Q, Q, of diodes D, D and MOSFET surrounded by a broken line is molded with the same resin, a terminal is output, i.e., modularized.
