摘要： A processor for processing photosensitive material having a first processing tank containing a first processing fluid containing at least one component of a first concentration and a second processing tank containing processing fluid having the same component to that of the first processing fluid, however, the concentration of the component being different than the first concentration. A weir is provided for causing fluid to flow from the first tank to the second tank resulting from the hydrostatic pressure of the first fluid in the first tank. The weir has a configuration such that concentration difference between processing fluid in said tanks does not change significantly over a predetermined period of time.

摘要： A medical assembly includes a multi-wire lead having a plurality of coiling loops. The multi-wire lead has a gap region and a non-gap region. The gap region has adjacent coiling loops of the multi-wire lead with gaps therebetween so as to form different impedance in the gap region than impedance in the non-gap region. The non-gap region has adjacent coiling loops of the multi-wire lead with no gaps therebetween. The gaps may provide inter-loop capacitance. The multi-wire lead may have a plurality of gap regions, each gap region having a non-gap region therebetween.
