Abstract: A training machine for enabling the exerciser to exercise under a load appropriate for the individual exercise capability and physical function of the exerciser. The exerciser (E) enters a desired velocity-load characteristic into a load characteristic input device (7), and the velocity-load characteristic is stored in the load characteristic memory device (8). A load instruction value is determined according to the velocity-load characteristic and to the velocity inputted from a velocity calculation means (6) into the load characteristic memory device (8) and transmitted to a control means (1). The control means (1) rotates a servomotor (2) with a torque instruction value corresponding to the load instruction value. A movement mechanism (3) converts the rotation into linear movement to move a movable unit (4). With this, the exerciser can carry out training of reciprocal movement.
Abstract: In calculation 3 phase AC output current Iu, Iv,Iw of an inverter based on the input DC current Idc of the inverter, it is difficult to detect the DC current Idc when the line-to-line voltage pulse width is narrow, thereby the DC current Idc pulse width becomes narrower.
The frequency Fc of the carrier wave C is lowered in a phase whose line-to-line voltage is high, thereby the DC current Idc pulse width is set wider. As a result, the current detection is enabled.
Abstract: An alarm notifying device comprising apparatus for inputting an alarm signal of a facility to be monitored, apparatus for connecting to a mail server for delivering an electronic mail by way of a communication line, a memory for storing a guidance text corresponding to the contents of an alarm, and a CPU having the function of transmitting an electronic mail about the alarm. In the alarm notifying device, the CPU has the function of adding the contents of an alarm and a guidance text corresponding to the alarm contents to an electronic mail.
