Mechanical Life Control Counter

       Disclosed is a technique for measuring mechanical life by
non-volatile read/write memories mounted on the mechanical
units/assemblies.  The technique is commonly applicable to all
mechanical/electrical portions.

      The technique will be understood by refering to the figure.
Each mechanical unit/assembly has a non-volatile read/write memory
and is connected to control circuits electrically. The
controller/microprocessor on the control circuits is able to access
the non-volatile read/write memory.

      The memory area of non-volatile read/write memory is assigned
to a counter area for counting the mechanical movement. The
controller/ microprocessor counts the mechanical action, and saves
the value into the non-volatile read/write memory. The
controller/microprocessor has the count value of mechanical life and
compares the counter value with saved life value. If the count is
greater than life value, the controller/microprocessor sends a
warning signal/message to the product operator/service
representative.

      In the case shown in the figure, the mechanical product has the
ASM-A and the ASM-B, and each ASM has a non-volatile read/write
memory.  The ASM-A has "NVRAM-A" (Non-Volatile Read/Write Memory-A)
for the "Function-A" and assigns the "Counter-A".   The ASM-B has
"NVRAM- B" (Non-Volatile Read/Write Memory-B) for the "Function-B"
and the "Function-C" assigns the "Counter-B" and the "Counter-C"
because the...
