Title: Semiconductor memory device
Inventor: OSHIMA TOSHIO
IPC: G06F21/62
Filed: 1987-03-16
Abstract: PURPOSE:To prevent wrong destruction of data and security leak in a semiconductor memory independently of a microprocessor by providing a comparing means which compares the password of the memory with that of a latch to set or inhibit a prescribed mode in the semiconductor memory. CONSTITUTION:When the input password coincides with the set password, a read control signal is outputted from a comparing circuit 8 to an output line 15 and a semiconductor 4 is to the readable state. This read control signal is supplied to a control circuit 3 also and it is judged that data read is permitted. The control circuit 3 sends an address signal to the semiconductor memory 4 through an address bus 11 and reads desired data from the semiconductor memory 4 through a data bus 10. If the input password does not coincide with the set password, the comparing circuit 8 does not output the read control signal because a flag of 'read inhibition' is stored in a password memory 7. Thus, the security of stored data is kept and destruction of stored data or the like is prevented.

Title: Long-life insurance system
Inventor: NAKAMATSU YOSHIRO
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To return the amount of decrease in the payment of insurance by an insurance company due to the extension of a subscriber's life according to the new health law based on rebuilding body to the insurance company and a long-lived subscriber. SOLUTION: An insurance system consists of a long-life benefit payment table at 160, 110 years old or the like, an explanation document for rebuilding a body, the table of the start date, due date, and premium of life insurance, and calculated scheduled death insurance sum, an actual death insurance sum, and a sum table that is obtained by subtracting the actual sum from the calculated sum. A curve shows that a life has been extended to 144 years old at a point F since rebuilding body for practicing specific training has been started, for example, at 40 years old at a point B when a subscriber joins, at 20 years old at a point A, an insurance of 70-80 years old where the due date is at a pint C.  As a result, an expenditure insurance total amount goes below a scheduled death insurance total, thus paying a long-life benefit at 100 years old in a point D and at 110 years old in a point E, for example, after a due date of approximately 90 years old from the difference that is obtained by subtracting the expenditure insurance total from the scheduled death insurance total being obtained from the rebuilding body.
