  • Patent number: 12105275
    Abstract: A light source device includes a semiconductor light source that radiates light at a light quantity according to an applied current, a circuit that determines a current instruction value based on control information, first and second drive units, each of the units that is connected to the semiconductor light source and the circuit, and is capable of outputting, to the semiconductor light source, a current having magnitude corresponding to the current instruction value. The control information is set based on brightness of an image captured by an imaging element. When one of the first and second drive units is switched to the other, the circuit causes the other to start the current output after an elapse of a predetermined stop time period having a length at a predetermined ratio or less to a frame rate on the imaging element since a stop of the current output from the one.

    Abstract: A second polymer is prepared through derivatization of a first polymer. Kendrick Mass Defect (KMD) analysis is applied on a mass spectrum of the second polymer, to thereby produce a plot. Meanwhile, a plurality of mass candidates for a non-primary-chain segment are calculated based on a mass spectrum of the first polymer. The KMD analysis is applied on the plurality of mass candidates, to thereby produce reference images. A mass of the non-primary-chain segment is identified through matching of two KMD analysis results.
