Abstract: A probe includes an insertion portion insertable into a body organ, a projecting portion being exposed to an outside of a body after the insertion portion is inserted into the body organ, a device mounting area onto which an external-device coupler is removably mountable, and sensing electrodes provided on the insertion portion and the device mounting area. When the insertion portion is inserted into the body organ, the sensing electrodes detect a biosignal and become conductive with coupling electrodes of the external-device coupler mounted onto the device mounting area. The probe is an electromyograph probe that detects a biosignal measurable by an electromyograph. The insertion portion and the projecting portion of the probe may be integrated or separate from each other. Both of the insertion portion and the projecting portion or only the insertion portion may be disposable.

Abstract: A circuit for providing an overcurrent protection for a power element, such as an IGBT, MOSFET or bipolar transistor, which is inserted between the power supply and a load, the protection circuit comprising a control circuit that provides an input to a gate amplifier at the power element gate. The gate amplifier comprises a photodiode that is connected between the amplifier power supply and the power element gate. The photodiode provides a clamp of the gate voltage in the event of an overcurrent and communicates optically with a phototransistor to provide a detection signal that can modify the control circuit operation. Specifically, the detection circuit can modify the input to the control circuit or control the output of the control circuit so that the energization of the power element is stopped or limited. The control can be through Darlington-connected transistors at the output of the phototransistor.

Abstract: An inverter unit for driving a motor with multi-phased currents, each of the phases being derived from a.c. input voltages that are applied to respective input terminals, rectified and smoothed by capacitors before being applied to parallel-connected switching elements to develop each of the phased a.c. outputs. The capacitors may be connected in series and/or in parallel together with the switching elements. In order to reduce the effect of the distributed inductance contributed by the conductors used to connect the capacitances and switches, and thus the need for large snubber capacitances to compensate for the distributed inductances, the connectors are given a geometry and an orientation that causes the inductances to be minimized. Specifically, the conductors are of a bus-plate form, having a large area for improving heat dissipation, and an orientation so that the magnitude and direction of currents flowing through the bus-plates tend to minimize the effect of the distributed inductances.
