The invention relates to small molecules which function as inhibitors of anti-apoptotic Bcl-2 family member proteins. At least part of the dispensing subassembly is preformed on the container and the remaining part of the dispenser subassembly is connectable therewith. The rotation phase angle measuring device also has a rotation phase angle calculator for calculating a phase angle of the voltage rotation vector in one pitch period including the above timing on the basis of the voltage amplitude value and the chord length value calculated by the above calculations. The first conductive film has an edge which is operative for emitting an electron beam.
