Abstract: An inverter device includes a motor, a power supply that supplies the motor with electric current, an inverter that, during regenerative operation of the motor, performs switching between a first state in which regenerative current generated in the motor is returned to the motor again and a second state in which the regenerative current is supplied to the power supply, a first detector that detects a first condition electrically acting on the inverter, a second detector that detects a second condition electrically acting on the power supply, and a determiner that performs a first determination to perform switching between the first state and the second state, based on a detection result by the first detector or the second detector.

Abstract: [Problem] A problem addressed by the present invention is to provide a novel fluorescent probe having excellent tissue permeability that is capable of detecting the peptidase activity expressed at a high level in cancer cells and the like as a response of long-wavelength red fluorescence.

Abstract: A process for producing a metallized plastic film comprising the steps of applying a masking oil supplied from an oil supply source to the surface of a rubber roll drivingly in rotation and having formed on its surface projections or indentations in conformity with the margin pattern to be formed, applying the masking oil on the surface of the rubber roll to the surface of a plastic film in a pattern substantially similar to the margin pattern, and forming a vacuum-evaporated metal film on the oil bearing surface of the plastic film. Margins can be formed in a desired pattern efficiently by this process.
