    • A data sharing method for use in a computer system provided with a first computer, a second computer and a data storage subsystem for connection with the first and second computers is disclosed. The data storage subsystem has a plurality of memory units and a control unit for controlling the plurality of memory units. The control unit forms a paired state of a first memory unit storing data for use by the first computer and a second memory unit, the paired state being so controlled as to match the contents of the first memory unit and those of the second memory unit. When data used by the first computer are to be used by the second computer, the control unit releases the paired state between the first memory unit and the second memory unit to stop updating of the first memory unit to be reflected in the second memory unit. After that, the control unit re-maps a third memory unit used by the second computer and the second memory unit with each other, and so performs control that the access by the second computer to the third memory unit be made to the second memory unit.

    • A three-axis acceleration sensor having a simple construction is provided for improving shock resistance without lowering sensor sensitivity. An acceleration sensor for detecting acceleration in three orthogonal directions comprises an electrode substrate pair including electrode substrates (4) opposed to each other, and each having fixed electrodes (4c, 4b, 4a) corresponding to three axes, respectively, a diaphragm (2) acting as a movable electrode, and an umbrella-like weight (3) mounted centrally of the diaphragm (2). Acceleration is detected based on variations in capacitance between the fixed electrodes (4c, 4b, 4a) and diaphragm (2). Each electrode substrate (4) has an electret layer (1) formed to cover surfaces of the fixed electrodes (4c, 4b, 4a). At least one of the electrode substrates defines, centrally thereof, a through hole (7). A shaft portion of the umbrella-like weight (3) extends through the through hole (7) from outside, and is connected to the diaphragm (2).

    • A trouble determining apparatus for a chopper type DC boosting circuit capable of determining whether or not a switching device is in trouble securely and quickly and when the switching circuit is in trouble, preventing other circuit from being in a trouble. Upon determining a short-circuit trouble of a transistor Q, a boosting circuit control unit 22 is turned OFF a power relay RL and then determines whether or not a voltage VP1 of a connecting point P1 rises over a first set voltage VS1 by the time when a first predetermined time t1 elapses since an ignition switch IG is turned ON with the transistor Q set to OFF. Upon determining an open trouble of the transistor Q, the boosting circuit control unit 22 determines whether or not the voltage VP1 of the connecting point P1 falls below a second set voltage by the time when a second predetermined time t2 elapses since the transistor Q is turned ON with the power relay RL set to OFF and whether or not the voltage VP1 falls from a state before the transistor Q is turned ON by more than a third set voltage.
